Application

AC contactor(hereafter refer to ac contactor)is mainly used in power system with AC 50Hz(or 60Hz), the rated working voltage up to 660V, under the application category of AC-3, when the rated working voltage 380V, the rated operating current to 300A electrical, for the long-distance range making and breaking the electric circuit, and combines the electormagnetism starter with the suitable thermal overload relay or the electronic protector to protect against the possible overload electric circuit during operation(running).

contactor

Q:What are the characteristics of permanent magnet AC contactors: The innovative technology of permanent magnet AC contactor is characterized by the use of permanent magnet drive mechanism to replace the traditional electromagnet drive mechanism

Q:Get the method of the relay time parameter: In the process of contact will produce bounce, and finally to achieve a stable state, during which the microcontroller data collected or 0 or 1. Set the sampling period of the microcontroller 0.01ms, the data collected by the microcontroller address value multiplied by the sampling period, that is, the required action time. [2]

Q:What is the noise-free function of traditional contactors?: so that static and dynamic silicon steel plate pull, when the grid voltage or dynamic silicon steel surface is uneven or dust, foreign objects, etc

Q:What about the release device and the contactor and the circuit breaker?: and undervoltage failure can automatically cut off the circuit, its function is equivalent to the fuse switch And a combination of overheat relays and the like.

Q:What causes the AC contactor to be damaged: . Increase the power capacity, replace the line repair control contact 3. Replace the coil

Q:What is the difference between the auxiliary system 01 and 10 of the AC contactor?: normally open contact is the contactor coil without electricity, Static contact is separate, non-conductive, generally used NC said, normal close

Q:Technical development of AC contactor: one of the basic feasible solution is to replace the AC power transformer transformer, and then through the internal rectifier into a DC power supply, but this complex control and Rare.

Q:The contactor is mainly composed: The other half is the activities of the core, structure and fixed iron core, to drive the main contacts and auxiliary contacts closed off.

Q:Contactor accessories have what roles?: insulation shell and accessories, all kinds of springs, transmission, short circuit, terminal and so on

Q:By the drive system, contact systems, arc and other components of the connector.: usually contactor are equipped with arc extinguishing device, the general use of semi-sealed vertical seam clay hood, and with a strong magnetic blown arc.
