VTK4-12 Indoor HV Vacuum Circuit Breaker

Adopting permanent magnet mechanism with excellent features. The mechanism adopts single steady-state magnetic circuit system, omitting the charging, lockout and other mechanical devices of traditional mechanism. Quantity of components is reduced upto 70% and above, which greatly improves the reliability and endurance.

CONTACT

Primary conductive circuit adopts solid insulation structure, via advanced ethoxyline seal. Combine the arc-control chamber, conductive circuit, insulation support and etc into a compositive seal post.And successfully solve the environmental withstand problem for vacuum breaker.Adopting all electronic intelligent control units, and the features are safe and reliable. 50, 000 mechanical endurance, realizes “free of maintenance”, and is applicable for frequent breaking circumstances.There are two types of structure trolley and fixed-type, which could be fitted with KYN28A, XGN2, GG-IA, and other switch cubicles, which could be convenient for oilless reform.
