Q:What are the principles of selection of contactors?
When the rated current of the contactor main contact is selected, the rated current of the main contact shall be equal to the rated current of the load
Q:Three-phase AC contactors have several useful clients?
. And note whether the contact point is normally closed or normally open. If there is self-locking control, according to the principle of the line on it.
Q:What about the release device and the contactor and the circuit breaker?
Circuit breaker according to its use is divided into high-voltage circuit breakers and low-voltage circuit breakers, high and low voltage line is more vague, generally more than 3kV called high-voltage electrical appliances.
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:Traditional communication contactor long life and long reliability?
Compared with the traditional contactor, permanent magnet AC contactor in closing, in addition to the same electromagnetic force, but also has the role of permanent magnetic force,
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
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.
Q:What is the role of the contactor
Contactor control capacity, suitable for frequent operation and remote control, automatic control system is one of the important components.
Q:he three-phase AC contactor has several wiring ports
Usually three-phase AC contactor upper and lower ends have three main lines, two sets of auxiliary contact terminals and a set of control coil side,
Q:How to get the relay time parameter
The literature refers to a relay time parameter computer detection method, which uses self-developed acquisition board, which is mainly composed of single-chip and its peripheral circuit
