Q:Technical development of AC contactor
Because the AC electromagnetic contactor coil is generally used AC power supply, in the contactor after the excitation, usually there will be a high decibel "slightly" noise, which is the characteristics of electromagnetic contactor
Q:How to measure the contactor is good or bad
Such as one of the work, the other does not work can be roughly determined to contact bad.
Q:A brief introduction to the power contactor
The AC contactor relies on a spring return after power failure. The other half is the activities of the core, the structure and fixed iron core, to drive the main contacts and auxiliary joints of the short
Q:The Development of Electrical Performance Testing Technology for Contactors
Through the analysis of the collected voltage signal, the time domain signal is transformed into the frequency domain signal by the fast Fourier transform. The result of the transformation is placed in the array of the real part and the imaginary part respectively.
Q:What are the classification of contactors?
DC current compared with the AC current, there is no periodic current value of the zero-crossing point, so the traditional contactor breaking circuit, the contact between the arc is more intense
Q:Seeking Star Triangle to start the contactor on and off the order and process
The picture of the triangle - the triangle shows you! And explain the process!
Q:By the drive system, contact systems, arc and other components of the connector.
arc extinguishing system: arc extinguishing device used to ensure that the contact disconnect the circuit
Q:Can the AC contactor cut off the short circuit current?
Because the AC contactor is only a switch-type device, no current detection and feedback device, so in practice, often with the appropriate thermal relay or electronic protection device into an electromagnetic starter, in order to protect the circuit may occur overload or phase failure.
Q:What does the contactor NC ON mean?
contact system, including three main contacts and one to two groups normally open, normally closed auxiliary
Q:Electrical performance test technical status related to the connector
With the continuous improvement of the level of electrical testing, SCM more and more applications to the detection and control of various types of electrical appliances.
