Q:The main structure of the contactor
20A above the contactor with an arc extinguishing cover, the use of the circuit when the electromagnetic force generated by breaking, quickly pull off the arc, the protection of contacts
Q:What are the types of AC contactors?
In order to quickly extinguish the arc when the break, usually contactor are equipped with arc extinguishing device, the general use of semi-sealed vertical seam clay hood, and with a strong magnetic blown arc.
Q:Various types of contactors are classified
connected to the circuit. In the above process, the coil itself has resistance, the continued consumption of electricity
Q:What are the principles of selection of contactors?
When the rated current of the contactor main contact is selected, the rated current of the main contact shall be equal to the rated current of the load
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: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
Q:How to connect the DC contactor to the circuit?
Have you seen the satellite days someone to close the knife? Dangerous high-current gate knife when the arc is wounding
Q:What does the contactor NC ON mean?
AC contactor is mainly composed of four parts: (1) electromagnetic system, including the attracting coil, moving core and static cor
Q:Use Star Triangle to start contactor's order and process method
Coil power, the motor to do triangular connection, and in the pressure operation, to achieve the star - triangular automatic switching buck starting. KM
Q:Dynamic Measurement Technology of Contactors and Comprehensive Evaluation Method
AC contactor dynamic test device to DSP as the core, build a variety of signal sensors, through the RS232 and the host computer for data communication.
