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:Traditional communication contactor long life and long reliability?
especially the voltage, current, magnetic gap increases easily lead to heat and the coil burned, and permanent magnetic contact device is not possible to burn the coil.
Q:What is the effect of the contactor coil parallel capacitor?
causing the surrounding electronic equipment, especially the PLC's electronic control equipment caused by interference, but also reduce the electrical life of the contacts.
Q:What is the main component 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:Similar terms for contactors and relays
The main function of the main circuit is to connect to or disconnect the main circuit. The so-called main circuit is a circuit is working or not by the circuit is connected to the mark.
Q:The Development of Electrical Performance Testing Technology for Contactors
The peak position is the grid frequency, Calculate the grid frequency using the formula
Q:Permanent magnet AC contactor working principle
The permanent magnet, which is fixed in the contactor linkage mechanism, is connected with the variable polarity soft magnet which is solidified on the base of the contactor so as to achieve the purpose of pulling
Q:Use Star Triangle to start contactor's order and process method
Coil power, its dynamic contact contact is broken, cut off the time relay coil circuit, so that time relay to stop working.
Q:Dynamic Measurement Technology of Contactors and Comprehensive Evaluation Method
At the same time, the contactor performance evaluation system has important reference value for the degradation of the contactor performance and the reliability estimation.
Q:Electrical performance test technical status related to the connector
The collected data is Fourier transformed, and the time domain signal is converted into a frequency domain signal to calculate the phase of the voltage and current, and the power factor is obtained
