JCZ5-12 Indoor vacuum contactor 12KV (fixed)

1. JCZ5 vacuum contactor is composed of insulation frame, metal base, transmission arm, electromagnetic system, auxiliary switch and vacuum arc extinguishing chamber. When the electromagnetic coil passes the control voltage, the armature drives the crank arm to turn, so that the main contact in the vacuum interrupter room is connected, and the main contact is broken after the electromagnetic coil is powered off due to the action of the opening spring.
2. The vacuum arc extinguishing chamber is composed of an upper cover, a lower cover, a metal bellows and a ceramic tube. The shell is made of corrugated porcelain tubes made of 95 porcelain insulating materials. It has the characteristics of large creepage distance, high mechanical strength, heat resistance and impact resistance.

3, the electromagnetic system considers the actual suction characteristics and reaction characteristics of good coordination, as well as the contactor to play the advantages of low noise and power saving, the use of DC double coil by starting and maintaining two windings,

4, mechanical lock: when the closing coil is energized, the contactor is closed, the mechanical lock is locked, when the trip coil is energized, the mechanical lock is released, the contactor is released, the trip coil is in a hot state, the voltage is in the range of Ue85%-110% to make the contactor reliable release.
