Q:Whether can the AC contactor cut off the short circuit current?
so that the main contact is disconnected and the auxiliary normally closed contact which is mechanically connected with the main contact is closed
Q:Why should the thermal relay be used with the AC contactor
If the fault occurs at this time, the motor is overloaded, then an excessively large current is applied to the thermal element of the thermal relay FR
Q:Distinguish contactor is good or bad
The coil winding value is about 200 feet. Before measuring the first line should be removed and then measured.
Q:Computer-centric development trend
Using Visual C ++ 6.0 software to develop the acquisition program and man-machine interface, the data processing program can carry on the real-time automatic processing to the data, has reduced the error caused by the manual processing waveform data.
Q:What does the contactor lock mean?
Self-protection is through the stop button to take a power cord connected to the contactor on the open end of the point, open the other end to the contactor coil, s
Q:The computer as a host computer
operating voltage, contact resistance Electrical parameters for testing. In the test of the action time, the relay will be tested normally closed contact high, normally open contact ground
Q:Contactor accessories have what roles?
arc extinguishing device, the general capacity of the larger AC contactor are equipped with arc extinguishing device, in order to quickly cut off the arc, from burning the main contact;
Q:How to get the relay time parameter
However, in this way, when the relay is connected to the DC load, the instantaneous value of the single-chip port voltage may be small or close to zero when the AC voltage is alternating due to the alternating current load.
Q:Current Status of Electrical Performance Testing Technology for Contactors
A self-developed A / D sampling board or DSP as the core of the high-speed data acquisition card, the contact pressure drop, disconnect the contact between the voltage
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
