- Q: Computer-centric development trend
- The device can realize real-time data acquisition of dynamic waveforms such as contact voltage and current for contactor and breaking process.
- Q: About introduction type of contactor
- Three, the permanent magnet actuator removed a series of complex cumbersome lock protection device in the electromagnetic mechanism
- 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 parts of the contactor
- electromagnetic actuator, bracket, auxiliary contacts and shell (or chassis) composition.
- 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: 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: What does the contactor lock mean?
- so after the start of the contactor point closure point, the coil can stop from the button Get the power, so that the formation of a self-preservation circuit.
- Q: How does the contactor interlock?
- The normally closed contacts of the KM2 contactor are connected in series to the coil circuit of the KM1 contactor, but if a contactor is welded
- Q: How many AC contactors are there?
- the main Contact mechanical connection of the auxiliary normally closed contact open, auxiliary normally open contact closed, thus turning on the power
- 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
