Q:What is the difference between a contactor and a circuit breaker?
Circuit breaker is a protective effect, can extinguish the arc, there are sub-ability. Contactor is the use of coil to control the circuit on and off, contactor power, the normally open to close, long closed open, so to control.
Q:What is the main component of the contactor?
one of which is fixed with a coil and a working voltage. select. In order to stabilize the magnetic force, the suction surface of the core is short-circuited. The AC contactor relies on a spring return after power failure.
Q:Use Star Triangle to start contactor's order and process method
Coil power, its dynamic contact contact is broken, cut off the time relay coil circuit, so that time relay to stop working.
Q:Various types of contactors are classified
his hybrid contactor uses the traditional DC contactor in the closed conduction state contact contact resistance is small, the conduction pressure drop is small, will be anti-parallel thyristor and control module unit composed of non-contact switch in parallel with the traditional DC Contactor contacts.
Q:Judge the contactor is good or bad
the amount of power to control the end of the line to remove the control, with a multimeter to beat the amount of foot, press the test end of the three main contacts and another group of normally open contacts, should be conductive
Q:What is the use of AC contactors?
If you want to add self-locking, then you also need to output from the terminal to a terminal connected to the control point above.
Q:Distinguish contactor is good or bad
often The closed contact should not turn on. Put down the test end, the main contact and normally open contact should not lead the normally closed contact should be conductive
Q:What is the effect of the contactor coil parallel capacitor?
Since the coil of the contactor is an inductor, the dt is very small due to the fact that the dt is very small at the external contact, so the Lx di / dt is very large and the coil produces a very high reverse electromotive force, which causes the contact of the off- Large arc
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
Q:The main classification of contactors
According to the operating mechanism is divided into: electromagnetic contactor, permanent magnet contactor.
