GW13-72.5 voltage transformer neutral point disconnecting switch

1,Operating range and characteristic

GW13 series neutral point disconnecting switch, exchange 50HZ the open air to fit, support it in no-load cases, divide, shut the neutral point on-line using of the voltage transformer. This disconnecting switch is divided into a general type and anti-pollution type two kinds.
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 CJ11M 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. CJ11M is non-maintaining type and CJ2, CJ6, the CJ16A type electronic actuating mechanism sees its specification separately.

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.


3,Structure and operating principle

Serial disconnecting switches are fixed on a base separately by two bar pillar electrical insulators, the intersection angle is 50 degrees. It is mainly made up of the part of the base, bar pillar electrical insulator and conductive part; There are two and is both as 50 degrees of bearing seat holes bases, the passage inclined plane corresponds to arc surface of the pedestal, make up the regulation part. The pedestal adopts the taper roller bearing, it is flexible and light to rotate; The bar pillar electrical insulator is fixed on the rotating plate in the pedestal, the conductive part is fixed on the electrical insulator top of bar pillar, it is the embedded structure of the copper pipe.

Two insulating pillars are fixed on the bearing in both ends of base, with the gear link of the umbrella type separately each time, the umbrella type gear can be moved up and down along the axle, in order to regulate the gear join states of two gears.

Each insulating pillar may competence is rotated, the corner is 90& deg; ,Equipped with the conduction band terminal base, 25& deg the insulating pillar; Red copper pressing plate, left, right stylus contact tube, terminal base and 25& deg of conduction band; Red copper pressing plate cramp contact tube through 4 the intersection of M10 and Hex Bolt (it fastens force moments to be 7-10 N· M, does not allow to exceed 10 N· m),The left, right stylus keeps in touch in the middle of two insulating pillars through the contact tube.

The conductor structure of major loop is the tube soft linkage of copper, the middle stylus is & ldquo; Hand-shake & rdquo; Type structure, its structure adopts the technical contact finger blade washer of the patent to cramp technology, it is a high pressure, self cleaning type, the contact finger contact pressure maitains unchanged for a long time, the contact finger spring has no passing of current, it is safe and reliable to run for a long time.
