Zw32 33kv Outdoor Mv Vacuum Circuit Breaker with Disconnector

Basic Info.
 

Product Description

Vacuum circuit breaker is a special type of electrical circuit breaker that is designed to rapidly open and close. Unlike circuit breakers, which are

designed to "trip" and stay in the open state, it can rapidly transition states from closed, to open and back. These devices aim to stop network faults

from causing long outages, by quickly restoring power. 

ZW32-40.5 series outdoor high-voltage vacuum circuit breakers(here in after referred as ''circuit breakers'')  adopts a unique design of integrated

sealed poleand high-reliability poerating mechanism. The device is mainly used in medium voltage overhead power grid, as a sub-, combined with

load current, overload current and short circuit current.

ZW32-12 Circuit breakers are outdoor distribution switchgear with rated voltage of 12KV and three-phase AC of 50HZ.

Circuit breaker is mainly used for opening and closing Load current, overload current and short-circuit current in power lines have overload and short-

circuit protection functions, meet the requirements of control and measurement, and can also realize remote control and motoring functions, which are

widely used in control and operation in distribution systems of substations and industrial and mining enterpries, and is especially suitable for places

requiring frequent operation.

ZW20-12 series outdoor high-voltage vacuum circuit breakers are outdoor distribution equipment with rated voltage of 12KV and three-phase AC of

50Hz. It adopts vacuum arc exitinguishing and as an insulating medium, SF6 gas is an improved product  of ZW20-12F post vacuum circuit breaker.

The gas sealing, explosion-proof and insulationn structure technology imported from Janpan Toshiba VSP5 is adopted. The sealing performance of

the input and outlet conduit has also been improved, and the overall sealing performance is excellent. The SF6 gas filled inside does not leak and is

not affected by the external environment. Its spring operating mechanism is miniaturized and reliability and stability optimization, using direct chain

main drive and multi-stage tripping system, the action reliability and stability are improved several times compared with the traditional spring

operating mechanism in China. Axis and sleeve of main circuit the contact between them adopts the adduction and extension bracelet structure, and

the contact resistance of the main circuit is small and the temprature rise is low. Therefore, ZW20-12F outdoor post vacuum circuit breaker is a

maintenance free product, which is a post beraker. The best product in road equipment.

ZW32-12F also adds overcurrent protection and mechanism spring energy storage indication, and is equipped with aviation socket for secondary

electrical connection, which is convenient to combine with intelligent controlloer. The electrical and mechanical properties make ZW20-12F outdoor

post vacuum circuit breaker widely used. It is mainly used to switch on and off the load current and short-circuit current of 10KV power system, and is

suitable for transformer. It is used for protection and control in distribution systems of power stations and industrial and mining enterprises, and is

more suitable for places where power grids are frequently operated. This product is matched with the controller and has excellent recloser function,

which can meet the automatic distribution chemical system requirements. 

ZW32 Circuit breakers meet technical standards such as GB1984-2003, DL/T 402-2007 and IEC60056.
