2.2 Contact lifeThe expected mean contact life of the arc-carrying diverter switch contacts can be estimated according to Fig. 8, depending on the relative load (Iu/Ium). Only approximate data can be provided, since the actual contact life is influenced by a wide range of operational factors (this does not apply to constant-current operation).

The inspection instructions must be followed.

2 Technical data

2.3 Rated withstand voltages of the internal insulationFigure 13 shows the voltage stresses at the tap winding for the three main basic connection types for three-pole on-load tap-changers and single-pole on-load tap-changers. When selecting an on-load tap-changer the maximum load at the tap selector must be verified in order to avoid the associated rated withstand voltages being exceed.

Figure 13 On-load tap-changer M III 350 Y ... M I 1503, specific voltage stresses at the tap winding (rated withstand voltages) (8997560D)

• a0 = between selected and preset diverter switch tapping.

• a1 = between fine tap selector contacts of the winding for one step (closed or open)

• a = between start and end of a fine tap changer winding; for versions with coarse tap changer winding also between start and end of a coarse tap changer winding.

Note for coarse tapping in (-) position of the change-over selector:For loads involving impulse voltage the permitted withstand voltage "a" between the end of a coarse tap changer win-ding connected to fine tap selector contact K and the fine tap selector contact at the end of the fine tap changer win-ding of the same phase must be taken into account.

• b = between the fine tap selector contacts for different phases and between change-over selector contacts for different phases connected to the start / end of a fine tap changer winding or a fine tap selector contact.

• f = between diverter switch lead and ground

Additionally for coarse tapping in ( + ) position of the change-over selector:

• c1 = from a ( - ) change-over selector contact to the lead for the same phase.

• c2 = between ( - ) change-over selector contacts for different phases.

CAUTIONThe maximum rated lightning withstand impulse voltage loads at a0 in the center positi-on must be taken into account!

2.4 On-load tap-changer OILTAP®M III 600 Y ... M I 1503 with coarse tap selector (up to 5 coarse taps)Fine voltage regulation requires a large number of operating positions that may necessitate

a multiple coarse tapping arrangement.

For example, with a 5-stage coarse winding and a fine tap changer winding with 18 tappings,

107 operating positions can be achieved.

The coarse tap selector is attached to both sides of the fine tap selector.

The on-load tap-changers are available for Um = 72.5 ... 300 kV and for 2 ... 5 coarse taps (tap selector size B, C and D).

3 Special types

3.1 Parallel bridges for parallel connection of tap selector planesOnly for on-load tap-changer OILTAP®M I 802 (803), M I 1203/1503 (see section 3, drawing no. 899598)For current division at the terminal contacts of the tap selector associated tap selector planes are connected in parallel, i.e.

• 2 tap selector planes for on-load tap-changer M I 802 (803),

• 3 tap selector planes for on-load tap-changer M I 1203 / 1503.

Parallel bridges at the tap selector terminals are required if the tap winding is wound in two or more strands and each of these strands taps into terminal contacts of the tap selector.

This measure reliably prevents

a) carry-over of compensating currents into the tap selector and diverter switch circuitsb) arc occurring during commutation at moved tap selector contact bridgesc) overvoltages between adjacent tap selector terminals connected in parallel

3.2 On-load tap-changer OILTAP®M I 603 and M I 803 with 3-sector diverter switchOn-load tap-changer models M I 603 and M I 803 @@ are supplied with a 3-sector diverter switch, if required.

This results in a higher step capacity (see Fig. 10) and/or a higher contact life of the arc-carrying diverter switch contacts.

3.3 On-load tap-changer OILTAP®M I 502 and M II 502 for 16 2/3 HzOn-load tap-changer models M I 502 (single-pole on-load tap-changer for single-phase transformers in any configuration) and M II 502 (two-pole on-load tap-changer for single-phase transformers with center-tap connection) are available for application in traction supply transformers with an operating frequency of 16 2/3 Hz. The on-load tap-changers are equipped with a special diverter switch. The tap change operation sequence and the dimensioning of the transition resistors are adapted to an operating frequency of 16 2/3 Hz (technical data are available on request).

3.4 Two-pole on-load tap-changer OILTAP®M II 352/502/602On-load tap-changer M II 352/502/602 is available as a two-pole on-load tap-changer for single-phase center-tap connection with technical specifications corresponding to on-load tap-changer M III 350 Y, M III 500 Y or M III 600 Y (see dimensional dra-wings, section 4).

On-load tap-changer combination for delta connection (example)On-load tap-changer M II 352 can also be used in conjunction with single-pole on-load tap-changer M I 351 as a two-column on-load tap-changer combination (M I 351/M II 352) for voltage regulation of transformer windings with delta connection (cor-respondingly with M I 501/M II 502 and M I 601/M II 602). This combination is referred to as M III K, see Figure 17.

The tap windings must be based on Figure 17.

3.5 On-load tap-changer OILTAP®M III 350 Y...M I 1503 for linear voltage regulation, up to 34 operating positionsThe high number of operating positions is achieved without change-over selectors through doubling of the tap selector contact planes compared with the standard version (leading to extended installation length).

The on-load tap-changers are available for Um = 72.5 ... 300 kV and several tap selector sizes (rated withstand voltages and di-mensional drawings are available on request).
