Q:Briefly describe the type of contactor

One, permanent magnet actuator to save a lot of energy to maintain the coil power consumption, environmental protection and energy conservation.

Q:Contactor dynamic performance detection technology and comprehensive evaluation method

. In this paper, the dynamic response of the contactor is tested, and the parameters of the contactor mechanical and electrical characteristics are extracted from the contact test waveform

Q:How to choose the contactor

that is, do not have to start the current to select the contactor, it is too loss.

Q:What is the difference between the contactor and the relay?

Electromagnetic relays and contactors, their working principle should be said to be the same

Q:What parts of the contactor

No matter what extent the development of technology, ordinary AC contactor still has its important position.

Q:Electrical performance test technical status related to the connector

contact electrical parameters of the main detection by the voltage, current transformers, data acquisition card and PC to complete.

Q:What is the difference between a safety contactor and a conventional contactor?

the performance is better than ordinary contactor, claiming to be a safety contactor.

Q:The working principle of permanent magnet AC contactor

From the power grid jump and jump, so as to maintain the stability of the production system

Q:What is the difference between a release, a contactor and a circuit breaker?

Detector is a switch circuit breaker or thermal relay inside a body, popular say that some of the monitoring circuit to reach a certain degree of time to trigger the trigger, the purpose is to control the circuit break.

Q:What are the classification of contactors?

DC current compared with the AC current, there is no periodic current value of the zero-crossing point, so the traditional contactor breaking circuit, the contact between the arc is more intense
