High voltage vacuum contactor

Vacuum contactor uses vacuum arc extinguishing chamber to frequently connect and cut off the normal working current. It is usually used to connect and disconnect 6kV, 380V(660V, 1140V) AC motors with frequent start and stop of medium and low voltage in a long distance.

Product Details

A high-voltage vacuum contactor is a switching device used in high-voltage circuits, which can safely connect and disconnect circuits in a high-voltage environment.
Working principle:
The core component of the high-voltage vacuum contactor is the vacuum interrupter, and its working principle is to use the vacuum medium to insulate and isolate the current in the high-voltage circuit. When the contactor is closed, the current enters another circuit through the contact point of the contactor to achieve the closure of the circuit. When the contactor is opened, the contact points are separated, and the current in the vacuum isolation area is forced to be interrupted to realize the disconnection of the circuit. Vacuum is widely used in high-voltage vacuum contactors because of its high dielectric strength, low leakage rate, fast power-off and long life.
Key features:
High operating frequency: the opening and closing frequency of the electromagnetic operating mechanism can reach 2000 times/hour.
Long mechanical life: The contactor is designed with high mechanical life, suitable for frequent operation.
Energy-saving design: using small contact pressure and low closing and opening speed, has the advantages of long life, energy saving and environmental protection.
Compact structure: small size, light weight, easy to install and integrate.
High reliability: Vacuum technology provides high reliability and safety.
Application areas:
High-voltage vacuum contactors are widely used in electric power, petrochemical, metallurgy, mining and other fields, and are often used in the control and protection of high-voltage motors.
