Q:With long life, long reliability is the advantages of traditional communication contactor
When the opening, the permanent magnet AC contactor in addition to the role of sub-gate spring
Q:What is the use of AC contactors?
Second: First, we should know the principle of AC contactor. He is using external power to the coil, resulting in electromagnetic fields.
Q:Application of Virtual Instrument Technology in Parameter Detection of Switchgear
Compared with the traditional compilation, VB, VC and other text programming language, LabDes software program is very simple to write. In the Lab VIEW environment to install the data acquisition card driver
Q:How to choose the contactor
contactor design has been considered to withstand the impact of starting current, so the choice of contactor do not have to consider the impact of starting the current
Q:How to connect the DC contactor to the circuit?
and some sites are dangerous people can not go to the power cord can not run everywhere, which requires remote control, high current places, dangerous places with contactors We are in a safe place to control
Q:What is the effect of the open contact of the AC contactor and the pushbutton switch?
Loosen the start button, although the button is disconnected from the coil, the coil is still passed through the auxiliary contact Control line connected, still have electric pull.
Q:Whether can the AC contactor cut off the short circuit current?
and the auxiliary normally open contact is disconnected , Thereby cutting off the power supply.
Q:Basic classification of AC contactors
The main contact function is to connect and break the main circuit, control the larger current, and auxiliary contact is in the control loop to meet the requirements of various control methods.
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:About introduction type of contactor
According to the main contact connection loop in the form of: straight Flow contactor, AC contactor
