Description

VS1-12 Fixed and sealing type high voltage vacuum circuit breaker (hereinafter called breaker) is indoor switch equipment of 12KV, used as protective and control unit in power system of mineral enterprises, suitable for switching on/off different loads and frequent operation, breaking short circuit current for many limes. 

VS I Series the breaker has very few of fixings, easy assembly, reliability and general application, long working life, prevent vacuum interrupter from outside impact and strike, avoid influence from pollution and dew, no flashover between phases, it meets completely with the requirement of creepage distance of grade II pollution zone specified in GB/DL standard. 


Product introduction and application

VS1-12 Fixed and sealing type high voltage vacuum circuit breaker (hereinafter called breaker) is indoor switch equipment of 12KV, used as protective and control unit in power system of mineral enterprises, suitable for switching on/off different loads and frequent operation, breaking short circuit current for many times. The product adopted VS1 + breaker operating mechanism, the primary part utilized the fixed and sealing pole column made by Siemens or similar in China, enclose vacuum interrupter and parts of main conductive circuit into an integral body, consequently the vacuum interrupter can avoid knock, access of dust and dew, working condition increased, and reduce the cost of maintenance. Which it realize operation without maintenance really; operating mechanism adopted module structure, and being verified by type test, it has E2 grade electrical endurance, M2 grade mechanical endurance, special driving mechanism can be used to form breaker handcart.
