1...24 kV
GeneralCompact dimensions, direct currentpaths, double-knife constructionand cast resin insulators are commonto all OJON -type disconnectors.The high short circuit strength ofthese disconnectors is a result ofthese features. Contact pressureis achieved by spiral springs whichcompress the knives.
Silver-plating prevents the contactarea of the contact and knives fromageing, and keeps the temperaturerise within the limits set by thestandards. Owing to the double-knifeconstruction, forces needed tooperate the disconnectors remainmoderate even at high rated currents.
The operating levers of the discon-nectors can be mounted on a flat
base. Busbar joints OJON�ZWJ 5and 6 may be used for disconnec-tors rated 2500 A and 4000 A. Theframes and levers of the discon-nectors are painted green, and theshaft terminals are treated withanti-rust varnish. The knives arepainted red, which makes theirposition clearly visible and gives apleasant look to the whole dis-connector.
The contacts of the disconnectorsare made of copper bar for 630 A andof cast copper for 1000...4000 A.Aluminium busbars can be con-nected, using jointing grease,to 630...1600 A, disconnectors,OJON�ZWJ 5 and 6 terminals andearthing switches.

Indoor type Disconnectors
Technical data and ordering information
Standards and operating conditionsThe disconnectors meet the requirements of IEC Publ. 129 (1984) and the Safety Regu-lations of the Finnish Electrical Inspectorate (Sähköturvallisuusmääräykset). In accordancewith the standards, the ambient site temperature for indoor disconnectors, must be�25 oC...+35 oC, and the access of unusually high quantities of dust, smoke, causticgasses and humidity to the site must be prevented.Disconnectors OJON 3�1 A 1000, OJON 3�1/1600, OJON 3�1 A 2500 and OJON 3�1A 4000 have been approved by the Register of Shipping of the U.S.S.R.
MountingNormally the disconnectors are mounted in the upright position with the hinges at thebottom. Other positions are also possible provided that the operating or locking deviceensure that the knives stay in the open or closed position. Wall mounting with the knivesin a horizontal position must, however, be avoided, as the knives may bend downsideways from the bearings.
Ordering information1. Type and quantity.

AccessoriesEarthing knives, operating arms and manualoperating devicesTechnical data and ordering information
Earthing KnivesAs shown in table 3 (page 6) the 630 A OJON_ disconnectors can be suppliedwith either an upper or lower earthing knives. Earthing knives have the sameshort-circuit strength as the corresponding disconnectors.
The main switch and earthing knives are interlocked with a locking deviceso that they cannot be closed simultaneously. The locking device is normallyon the left side of the disconnectors. A locking device prevents the earthingknife from opening and closing under its own weight.
Disconnector controlThe following can be used as an operating mechanism for the disconnectors:� operating rod NWA�ZS 5 (>1 kV) or NWA-ZS 6 (< 1 kV) and hook end
NWA�ZH 6 and arm YASKA 25� manual operating mechanism OJO�ZA 1 or UEKO 2C3� motor-operated control mechanism UEMC 40_. Refer to catalogue
34 UEMC 36_ and 34 UEMC 44_.
Motor Operating device UEMC 40_The type and construction of motor operating device depends on the locationand accessories required. The device can be fitted to the disconnectorshaft or the front of the cubicle. When mounting on the shaft, check that thereis enough space between the disconnector shaft and mounting surface. Whenthe motor operating device is fitted on the front of the cubicle, the drive istransfered using a lever system. Local electrical control (Pushbuttons) of theoperating device is available.Manual operation is also possible by using an operating rod or control handlewhen a motor operating device is fitted.
Operating armThe simplest control mechanism is an operating arm and an operating rod.Opening of the disconnector can be prevented with locking coil OJO�ZLA 6.
Manual operating mechanism, alternative A,OJO-ZA 1The manual operating mechanism OJO�ZA 1 for mounting on the front wallof the cubicle, interlocks the disconnector in the extreme positions with thehelp of a stall lever. A suspended pin ensures retention in these positions. Theend that comes through the front panel of the cubicle is covered with aprotective cover that can be locked with a padlock. The manual operatingmechanism can be supplied both with locking coil OKO�ZLA 3 and auxiliaryswitch OLAN�AL 1. When there is no auxiliary voltage, the interlock (of thelocking coil) can be opened manually. In accordance with the standards, theclosing movement of the disconnector is from down-position to up-position.

Manual operating mechanism, alternative B,UEKO 2C3This manual operating mechanism comprises of a beveled gear on the endof a shaft from the disconnector, a joint fitted with a position indicator onthe front panel and a control tube joining the two parts. Due to the joint,the control tube can be moved through an angle of ±40 degrees from theverticle position. The tube is to be cut to a suiatble length when installing.The indicator locks the disconnector in the extreame positions. The operatingmechanism may also be locking with a locking coil UEKO-ZL 1 and padlock.By turning the angle of the beveled gears the operating direction of thedisconnector can be adjusted to always be the same.

Technical data and ordering information
InterlockingThe use of locking devices in connection with different disconnectors isdetailed in table 3, page 6.
A. Disconnector interlocking when subject to gravity orshort-circuit and other disturbances
When operating arm controlled, the disconnectors are interlocked with lockingdevice OJO�ZE_ or locking coil OKO�ZLA 6. When the disconnector ismounted in a horizontal plane, locking device OJO�ZE_ must always be usedto prevent the knives from closing under their own weight. Manual operatingmechanism OJO�ZA 1 locks the disconnector in the closed and the openposition with no additional equipment.
B. Disconnector interlocking to prevent unintentionaloperation
When operating arm controlled, locking coil OJO�ZLA 6, which is fixed to theframe of the disconnector is used. Manual operating mechanism OJO�ZA 1can be locked with a padlock or locking coil OJO�ZLA 3. Manual operatingmechanism type UEKO 2C3 can be locked with a padlock or locking coilUEKO-ZL 1.
Locking coilsThe auxiliary control voltage of locking coils (OJO�ZLA 3 and 6) is eitherDC or full-wave rectified alternating current. In the absence of voltage, theinterlock can be opened by pulling the armature with the operating rod or byhand. Locking coil OJO-ZLA 3 is used with the operating mechanism whilelocking coil used OJO�ZLA 6 is fixed to the left or right side of the disconnector.Locking coil UEKO-ZL1 is to be fitted to the manual operating mechanismUEKO 2C3 position indicating device on the inside of the cubicle.
