110kv neutral point high voltage isolating switch technical requirement

Description of products

The neutral point disconnecting switch of the Model GW8 is a single phase alternating current 50Hz high-pressure switch apparatus, rated current: 630A, 1250A. 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. Also use while supporting the railway automatic block letter thing device. Combine but the use of single stage. Requirement that can meet the heavy users of filthy area of defending the corrupt disconnecting switch among them, and can solve the pollution flashover problem that the disconnecting switch appears in operation effectively.

This product is divided into a general type and antipollution type (W) Two kinds;

The matched actuating mechanism of this product is: CS8-5 type manual operating mechanism or electric motor operating mechanism of the Model CX6; CS17-G type manual operating mechanism or CJ2, CJ5, CJ6, Model CJ12 electric motor operating mechanism.

Environment for use

The height above sea level is less than 1000m ' Can offer the special requirement) ;

The air temperature around: +40 ¡æ lower limit of upgrade - 25 ¡æ;

The wind pressure is less than 700Pa (equivalent to the wind speed 34m/s) ;

The earthquake intensity does not exceed 8 degrees;

Thickness 10mm of ice coating;

The filthy intensity of air: 0 grades (ordinary grade) , II, III (anti-pollution type) .

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 ".


GW8-126110kv neutral point high voltage isolating switch technical requirement principle and structure

Originally disconnecting switch ' The appearance is shown in Fig. 1) By the base, pillar electrical insulator and conductive part make up, is equipped with the fixed contact and links mother's collinear wiring board the insulating pillar, there are bases, moving contact, operate the connecting lever, operation electrical insulator between pillar electrical insulator and insulating pillar, the actuating mechanism links with moving contact through connecting rod, operation electrical insulator, connecting lever of operation.
