Q:Get the method of the relay time parameter
The detection principle is: when the relay coil when the contacts through the action time to be able to close, so the first chip to collect data 0, contacts closed after the acquisition of 1
Q:The main structure of the contactor
The service life of the contactor is very high, the mechanical life is usually several million to ten million times, and the electrical life is generally several hundred thousand to several million times.
Q:What is the noise-free function of traditional contactors?
there will be noise. While the permanent magnet AC contactor is held by the permanent magnet force to maintain, so there will be no noise generated.
Q:Three-phase AC contactor has several terminals that have a role
Output and input are corresponding, it is easy to see. 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:The key structure of the contactor
Semiconductor contactor: The semiconductor contactor is a contactor that performs current operation by changing the conduction state and the open state of the circuit circuit.
Q:What is the main structure of the contactor?
AC contactor contacts, made of silver tungsten alloy, with good conductivity and high temperature ablation
Q:Contactor accessories have what roles?
AC contactor auxiliary contact is used to control the three-phase AC three fire lines; auxiliary contact is used to achieve:
Q:Research on Relay Parameter Detection Technology Based on Single Chip
Similarly, the release time of the relay can be obtained. At the same time the test device can also monitor the contact resistance of the contacts.
Q:How does the contactor works
so that contact recovery, normally open contact open, normally closed contact closed.
Q:Briefly describe the type of contactor
sub-gate power, commonly known as "electromagnetic action, Magnetic hold, electronic control ". In the process of closing and closing the motion, the electromagnetic attraction
