Q:What is the main structure of the contactor?
The main contact is generally open contact, and auxiliary contacts often have two pairs of normally open contacts and normally closed contacts, small contactors are often used as intermediate relay with the main circuit.
Q:What is the power contactor
AC contactor contacts, made of silver tungsten alloy, with good conductivity and high temperature ablation.
Q:Distinguish contactor is good or bad
so when the press work, then the contact is broken (Note: in the use of this method should pay attention to safety) KFR-7203LW / D wiring problems.
Q:The Role of Virtual Instrument Technology in the Parameter Detection of Switchgear Cabinet
The principle of detection is that when the relay contact is closed, the input voltage is 5V and the port is "1"
Q:Get the method of the relay time parameter
The single-chip computer is connected with the coil drive circuit to control the energizing and discharging of the excitation coil, collecting the state of the contact when the relay is closed and broken, and calculating its time parameter
Q:Judge the contactor is good or bad
listen: A, listen to whether it has a very loud squeaky sound, if possible may be (1) the power supply voltage is low
Q:The computer as a host computer
in the detection of the coil rated voltage at the same time start the timer to start timing, build contact level detection circuit real-time monitoring Change of contact level
Q:Application of Virtual Instrument Technology in Parameter Detection of Switchgear
The traditional detection method has the advantages of slow speed, large error and inaccurate measurement
Q:Similar terms for contactors and relays
Therefore, as the first floor of a friend said, large capacity of the contactor are generally equipped with an arc cover (because the high current disconnect will produce arc, do not use arc extinguishing, head).
Q:The key structure of the contactor
Vacuum contactor: Vacuum contactor is the contact system using vacuum degaussing chamber contactor.
