Product Features |
VT18 series indoor AC high voltage vacuum circuit breaker adopts the front and back arrangement structure, which is fixed on the inner and outer walls of the inflatable compartment. The circuit breaker adopts an open structure and is placed in the SF6 gas room, which is conducive to the heat dissipation of the main circuit and can meet the requirements of insulation coordination. The electrical connection of the main circuit adopts fixed connection and has high reliability. The operating mechanism adopts the spring operating mechanism specially designed for this new type of circuit breaker, which is installed in the circuit breaker frame. Its structural characteristics are more suitable for the front and back layout of the circuit breaker, and become an integral part of the overall structure of the circuit breaker. The design of the mechanism is simple, and the output curve is well matched with the requirements of the arc extinguishing chamber. |
