ZW30 (A ) High Voltage Vacuum Circuit Breaker 33 kv Outdoor Type vcb

 

 Product description

 

ZW30-33 type is three-phase ac 50 hz, high voltage switch equipment, mainly used for the 33kV power transmission and transformation system control and protection, can also be used for city and township power grid and the industrial and mining enterprises normal operation and short circuit protection, and can be used as a contact circuit breaker and movable capacitor group, especially suitable for frequent operation.

 

In outdoor ZW30-33 type high-pressure sulfur hexafluoride circuit breaker on the basis of development ZW30A - 33 type of outdoor high voltage vacuum circuit breaker, as the external current transformer, with CT17 type spring operation mechanism. Three pole body is installed on a common chassis, central operating mechanism underneath their chassis, chassis equipped with current transformer bays, outdoor placed on current transformer independently. Circuit breaker three pole mechanical linkage operation, with copper pipe connected with the electrode gas extremely. Arcing chamber located in the porcelain set inside, on the principle of vacuum arcing chamber, vacuum arcing chamber choose well-known manufacturers products.

 

 

 Feature advantages

 1, using vacuum arcing chamber, with SF6 gas as auxiliary insulating medium, with spring operating mechanism, realizes the devoid of oil;

 2, open circuit performance is good, long life, is 20 times;

 3, can open circuit current is 630 a single capacitor group without renewed;

 4, mechanical life is long, can reach 10000 times, reliable action, frequent operation, low noise;

 5, has lost the breaking capacity, can be used for contact circuit breaker;

 6, according to user requirements, can not with CT or most with 12 CT;

 7, products, beautiful shape, anti-corrosion ability is strong, simple structure, no maintenance cycle is long and easy in maintenance.
