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: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:What is the difference between a contactor and a circuit breaker?
There are some undervoltage, overvoltage and other protection functions
Q:Three-phase AC contactor has several terminals that have a role
The power is applied and the contact point is disconnected after power failure
Q:What are the characteristics of permanent magnet AC contactors
only by the weak signal current (0.8-1.5mA). Microelectronic module contains six basic parts: 1. Power supply rectification
Q:On the difference between the contactor and the relay
so that the contactor to work the current is also very large, that is to say its control circuit flows through the current is very large, with ordinary relays difficult to turn off its control circuit
Q:What is the scope of use of AC contactors?
Know the principle, you should figure out the connection of the external power supply, that is, the coil of the two contacts
Q:Contactor mainly by the drive system, contact system, arc and other components.
and auxiliary contact is in the control loop to meet the requirements of various control methods
Q:With long life, long reliability is the advantages of traditional communication contactor
closing speed faster than the traditional AC contactor, the detection, permanent magnet exchange Contactor closing time is generally less than 20ms, while the traditional contactor closing speed is generally about 60ms
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
