GW13-126/630A outdoor neutral point disconnecting switch

, neutral point plant supply: Appearance electric Co., Ltd. of Xi'an China

The disconnecting switch is a series of with a unipolar and matched manual organization or electronic organization, and enclose and install the required spare part.

The neutral point isolates the switching declaration:

2.1 Summary

The intersection of GW13-126/630A and outdoor the intersection of neutral point and disconnecting switch, it is the intersection of three-phase alternating current and 50Hz, specified voltage class that fit for the open air of 110KV, support it in cases there is no load, divide, shut the neutral point on-line using of the voltage transformer.

The GW13-126 type outdoor high voltage isolating switch offers the neutral point of voltage transformer in cases there is voltage to be non-loaded, connect Herba Euphorbiae Humifusae to the intersection of voltage transformer and neutral dot and line go on, divide into and shut use, thus realize the intersection of voltage transformer and neutral earth or two kind non-grounded freedom switch of run mode. In cases there is voltage not to be loaded, make and divide, shut the using of the neutral point ground path of the voltage transformer.

2.2 Structural and brief introduction of

Disconnecting switch, mainly and the base, pillar electrical insulator, terminal base, left stylus are assembled, the right stylus is assembled etc. and made up partly. It is fixed on a base respectively by bar electrical insulator and 35KV bar insulator of an upright corresponding voltage class, its intersection angle 50& deg; Form one & ldquo; V” Type structure,it is last deg not to last each base; The angular underframe is assembled. This disconnecting switch is divided into a general type and anti-pollution type two kinds.

2.3 Actuating mechanism

This disconnecting switch of reliable performance, simple in construction, complete in specifications. According to the needs of user, can adopt the manual actuating mechanism or electronic actuating mechanism to operate. Manual actuating mechanism, for CS17-G type, for the intersection of CJ12A-G and getting non-maintaining or CJ2, CJ6, CJ16A type electronic actuating mechanism. The CS17-G type manual actuating mechanism can enclose and install the electromagnetic lock of the Model DSW4-Y, in order to realize electrical interlocks, prevent the electric fault-operation. CF12A-G is non-maintaining type and CJ2, CJ6, the CJ16A type electronic actuating mechanism sees its specification separately.

Use and add the condition

3.1 Carry out the standard

This serial disconnecting switches are satisfied GB1985-89 " exchanging the high voltage isolating switch " IEC129( 1984) " exchange the earthing switch of the disconnecting switch " and IEC694( 1980) Every specified requirement that " high-pressure switch apparatus and control equipment share the clause ".

3.2 Environment for use
a. It is less than 1000m that above sea level;
b. The air temperature around: +40 degrees of upgrade, lower limit - 40 degrees;
c. The wind pressure is less than 700Pa;
d. The earthquake intensity does not exceed 8 grades;
e. The thickness of ice coating is not greater than 10mm;
f. The filthy grade of electrical insulator of the pillar: The general type is 0 grades, anti-pollution type is according to the request of user.


1,Improve the rotary table structure of the bearing, make the pedestal realize the waterproof function. And is furnished with the oil charging hole, adjust the screw, the globality of the switch is strong and maintains simpler, convenienter. Fifth, products characteristic GW13-126/630A outdoor neutral point disconnecting switch

2,Adopt the brazing craft between conductor pole and stylus, between conductor pole and contact finger seat, in addition the contact finger, with installing the flexible joint additionally between the contact finger stands, make the major loop resistance ratio of the products adopt the decrease by a wide margin of the screw joint, thus reduce the question of generating heat in operation of stylus. Earth the guide arm and adopt the aluminum alloy with of good performance electric conduction, the stylus part adopts copper castings, junction with base of conductor pole and earthing the contact finger with installing the flexible joint additionally between the contact finger stands, so the enhancement that the conductivity of the ground loop is big.
3,The electric conduction exposes and adopts the silver plated surface treatment technology of red copper partly, silver plate is dealt with, the surface is bright and clean, esthetic, corrosion resistance is strong, lasting and durable.
4,Improve the way of cooperating with hole of the axle: The iron cooperates with copper to change into copper cooperating with copper or stainless steel cooperates with copper, the phenomenon that the ones that have solved and used appearing for a long time outdoors have killed. Expose the standard component and adopt the stainless steel; The hardware adopts hot dip galvanizing to deal with, the corrosion-resistant ability of the switch is stronger.

Sixth, install the outside drawing of the size:

GW13-72.5kV, 126kV type outdoor neutral point disconnecting switch - unite and hold pursuing (mix CS17 or CJ6 electronic organization)

GW13 the intersection of neutral point and gap single pole unite and install pursuing ' Take the lighting arrester) : See and install the outside drawing of the size
