Siemens Vacuum Recloser 3AD Description

9229 0040 176 0B 13 2009-03-31

2 Description

2.1 Recloser principle and design

Reclosers are used in distribution systems. Like circuit-breakers they are in charge of making and breaking normal and fault currents. They are fully equipped with sensors and the controller being the protection and control device. In case of line fault, they can break and make several times, thus avoiding longer network interruptions due to temporary faults.

3AD vacuum reclosers are outdoor circuit-breakers designed for repeated opening and reclosing in case of fault.

The vacuum recloser consists of two main components: Switch unit (circuit-breaker, see Fig. 4) and control cubicle (see Fig. 5).

The development, design and testing of the vacuum recloser is based on current regulations and standards and state-of-the-art technology. The product conforms to the following standards:

– IEEE C37.60 – IEC 60255-22-4 Class IV – IEC 60255-11 – IEC 60255-22-5 – IEC 60255-21-1 Class I – IEC 60255-22-6 – IEC 60255-21-2 Class I – IEC 60255-25 – IEC 60255-21-3 Class I – IEC 6255-5 – IEC 60255-22-1 Class III – IEC 62271-1 – IEC 60255-22-2 Class IV – IEC 62271-111 – IEC 60255-22-3 Class III

2.2 Switch unit with embedded vacuum interrupter

The switch unit comprises of the poles, the operating mechanism and the housing. The side sections with the support feet, form the basis of the switch unit. In this way, the switch unit can be fixed to the pole mounting frame (see chapter 2.3.3 Auxiliary power supply) or placed on the floor.

2.2.1 Pole

The poles are made from cycloaliphatic epoxy resin, specially designed for outdoor use, in which the vacuum interrupters are located. In addition each pole contains a current transformer and an optional voltage sensor.

The sequence of the poles is C – B - A (sequence left to right). This is marked on the operating mechanism housing by identification indents. (A = 1 dent, B = 2 dents and C = 3 dents) This sequence is equal to the currents IA, IB and IC of the controller.

Fig. 12 Pole with integrated vacuum interrupter

Fig. 13 Pole sequence

2.2.1.1 Current transformer

The Vacuum Recloser 3AD is equipped with one integrated current transformer per pole. The current transformer is of the conventional type and has a ratio of 800 A : 1 A. It is for protection purposes and optimized for operation with the controller (see chapter 2.3 Control cubicle). However, the secondary signal is based on IEC 60044-1 and could also be used by any other controller.

The secondary wires of the current transformer are connected to a varistor for each pole in the switch unit. This prevents the occurrence of high voltages, if the control cable is removed while the switch unit is in operation.

DANGER High voltage – Danger to life and malfunction of the current transformer! The varistors installed in the switch unit must not be removed.

The signal transfer from the current transformers to the controller is by the control cable, i. e. a separate cable is not required.


9229 0040 176 0B 15 2009-03-31

2.2.1.2 Voltage sensor (optional)

The Vacuum Recloser 3AD can be equipped with integrated resistive voltage sensors (ordering option). They have a high level of accuracy and are used both for measurement and protection purposes. The ratio is adapted to operation with the controller (see chapter 2.3 Control cubicle) and provides a 110 V/√3 secondary signal.

No other controller should be used for the voltage measurement, since otherwise the ratio would be changed. An optional separate sensor cable equipped with special screening is used for the signal transfer from the voltage sensors to the controller. This results in a high level of accuracy and protection against disturbances. The sensor cable is connected at the back of the operating mechanism housing, next to the control cable.

The secondary wires of the voltage sensors are connected to a varistor for each pole in the switch unit. This prevents the occurrence of high voltage on the sensor cable, if the sensor cable is removed while the switch unit is in operation. The varistor must not be removed!

DANGER High voltage – Danger to life and malfunction of the voltage sensor! The varistors installed in the switch unit must not be removed.

2.2.2 Operating mechanism

The operating mechanism for the vacuum interrupters is located in a metallic housing. To meet the required fast reclosing cycles a magnetic actuator with capacitors as energy storage drives the switch unit. A gang operated mechanism connects the magnetic actuator with the vacuum interrupters

The operating mechanism is equipped with anti-condensation heating. It is operated together with the heating in the control cubicle and controlled by a thermostat.

A mechanical position indicator is easily visible from the ground and shows the current switch position of the recloser. The coloured display is reflective in the dark when using a torch.

16 9229 0040 176 0B 2009-03-31

2.2.2.1 Lock-out handle

A lock-out handle with ring protrudes from the operating mechanism housing. The ring is coloured bright yellow and is therefore easily seen.

By pulling the lock-out handle, the recloser opens and remains locked in this position. The locking has a dual electrical effect: It locks out both the controller and the electronics. It also mechanically locks the magnetic actuator.

As long as the lock-out handle is fully pulled out, it is not possible to close the switch unit electrically, neither locally nor from the control room. The interlocking is not removed until the lock-out handle has been completely pushed in. After this the switch unit can be closed electrically , either locally or from the control room.

The switching is described in Chapter (see chapter 4 Operation).

2.2.2.2 Operations counter

A mechanical operations counter is installed at the bottom of the switch unit. It records the total number of switching operations, independently of the electrical recording in the controller. The operations counter is used to keep track of the total number of operations of the switch unit in case the controller gets replaced or reset, alongside the electronic resettable counter in the controller.

9229 0040 176 0B 17 2009-03-31

2.2.3 Pole mounting frame

A pole mounting frame is used to install the switch unit on the overhead line pole, which can also optionally take up surge arresters (see Fig. 17 ).

It is recommended that at least one M20 bolt is used as a king bolt to fix the pole mounting frame to the pole. A different size can be used in line with local installation standards.

For installing within substations, a special frame is available for (not shown here).

2.3.1 Discharge switch for the capacitors

The "service switch" on the SUD module / printed circuit board 2 serves to discharge the capacitor. In the "service" position (right position), the capacitor charging operation is turned off and the capacitor discharged via a resistor - this procedure takes roughly one minute.

In this operating mode the red discharge LED next to the switch shows that the voltage at the capacitor is more than 40V (LED on). Work on the capacitor may only be carried out once the LED no longer lights up.

Before commissioning, the switch must be brought into the "Operation" position (left position shown on Fig. 22) – however, the LED does not light up during operation.

Note: During operation, the toggle switch (58) must be in the operating position (pointing left).

For maintenance work, the toggle switch (58) must be in the discharge capacitors position (pointing right).

2.3.2 Controller

The controller is the protection and control device for the recloser. It allows operation on site and parameter updates. Function keys and display elements, as well as an interface for the connection of a laptop, are available to the user. All functions and settings can be accessed and modified directly at the controller.

The relay incorporates two levels of password protection – one for settings, the other for control functions. The Settings Password prevents unauthorized changes to settings from the front fascia or over the data communication channel(s). The Control Password prevents unauthorized operation of controls in the relay Control Menu from the front fascia.

The relay is supplied with the passwords set to NONE, i. e. the password feature is disabled. The password must be entered twice as a security measure against accidental changes. Once a password has been entered then it will be required thereafter to change settings or initiate control commands.

Once the password has been validated, the user is ‘logged on’ and any further changes can be made without re-entering the password. If no more changes are made within 1 hour then the user will automatically be ‘logged off’, re-enabling the password feature.

The Control Cubicle works on an internal 48 V bus, which is secured by rechargeable batteries as an uninterruptible power supply. This internal bus is energized by PCB1 and charges both batteries and capacitors. Charging of the batteries is automatically compensated for temperature.

PCB1 is supplied by auxiliary power provided on site, either through LV supply or individual power transformer (optional). This supply needs to be connected to –X1 (Fig. 50). PCB1 is then protected by miniature circuit breaker F1.

The same supply is used for the heater and the GPO. They are protected by miniature circuit breaker F2.

2.3.4 Rechargeable batteries

Four 12 V batteries are supplied with the recloser. They are to be installed in series on site (see Chapter 3 Installation and Commissioning). The batteries are protected by the miniature circuit breaker F3 behind the swing frame. The batteries ensure minimal stand-by operation for 48 hours at 20 °C.

Note: If F3 is operated it directly cuts the power for the Controller, i. e. the controller will neither operate the Recloser nor protect the network. It restarts automatically by closing F3.

If the batteries are not in use they should be recharged after 6 month.

At tempratures above +50 °C, the estimated life of the batteries is much reduced.

Siemens Vacuum Recloser 3AD Operation

9229 0040 176 0B 37 2009-03-31

4 Operation The extent and content of the provisions for operating the recloser are determined by the fact that the recloser is just one part of a network . The operator of the recloser must adapt his operating instructions to the respective manufacturer's documentation and regulations. This ensures reliable, safe and trouble-free operation of the recloser.

4.1 Safety instructions for operation

In addition to the local safety rules and work practices, special precaution must be taken:

• The accessories required to operate the recloser must be stored in a clean location and must be checked regularly for completeness and good condition.

• All keys must be accessible only to the authorised operating personnel.

• No modifications must be carried out on the recloser. This includes but is not limited to removal of parts, opening the operating mechanism housing, and intervention with the drive system of the recloser.

• The control cable and the optional sensor cable must not be removed during operation. Removing these cables would mean that no further electrical operation would be carried out, and no measurement values or other signals can be sent from the switch unit to the controller.

DANGER Live parts on the switch unit and in the control cubicle - Danger to life.

• Do not work in close proximity to live components without isolating and earthing them. Special rules apply for intended live line working.

• Do not touch live parts

• Ensure that only qualified and authorised personnel, who are familiar with the operating instructions and observe the safety precautions, operate the equipment and carry out the switching operation.

• Opening of the swing frame is intended for maintenance purposes only and allows access to live parts.

• Do not pull of the connectors of control and sensor cable – live parts on the contact section.

4.2 Switching

Switching comprises electrical switching (remote and local operation) and mechanical switching ("lock out").

Switching is carried out automatically by the controller to protect the network, by remote control from the control room, or manually on site.

6.1.7 Installation heights – height correction factor

The insulating capability of insulation in air decreases as the height increases, due to the reduced air density. The stated rated lightning impulse voltage values (see Chapter 6.1.1) are valid according to IEC 62271-1 up to an installation height of 1,000 m above sea level. Above a height of 1,000 m, the insulation level must be corrected in line with Fig. 51:

Fig. 51 Height correction factor Ka

Example

For a required rated power-frequency withstand voltage of 110 kV at a height of 2,500 m, an insulation level of at least 132 kV is required under standard reference atmosphere.
