Q:Nvestigation on Detection Technology of Relay Parameters of Single Chip
The Lab VIEW application library loads a number of different test and control modules that allow users to implement a variety of test functions directly under the Lab VIEW application
Q:he three-phase AC contactor has several wiring ports
Control coil is when the coil is energized, the AC contactor pulls in, the main circuit is connected
Q:What types of contactors can be divided into?
but joined the permanent magnet on the core of the attraction, the use of energy storage capacitor charge and discharge to provide closing
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 is the role of the contactor
Can be frequently connected with the high current control (up to 800A) circuit device, so often used in the motor as a control object, can also be used to control the plant
Q:On the difference between the contactor and the relay
At this time, you can choose an original as a contactor to use the electrical appliances as the control circuit with the off, the contactor in this case is the role of the relay.
Q:How is the DC contactor connected to the circuit
First talk about the role of contactor: with a small current switch to control the high current electrical appliances;
Q:Contactor mainly by the drive system, contact system, arc and other components.
drive system: the drive system, including electronic modules, soft iron, permanent magnet, is an important part of permanent magnet contactor, relying on it to drive the contact closure and disconnect
Q:What is the power contactor
AC contactors are widely used as power break and control circuits. (Play the role of frequent switching)
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
