L0504-Murata muRata common mode inductor 90Ω 150mA The method of identifying the three poles of the thyristor module is very simple. According to the principle of the PN junction, it is only necessary to measure the resistance value between the three poles with a multimeter. Many customers have many problems in identifying the three poles of thyristor modules due to the lack of relevant knowledge in this area. The following details: The forward and reverse resistance between the anode and the...
The thyristor electronic non-contact switch not only has the advantages of zero-crossing, small inrush current and no over-voltage, but also can solve the problem of heat dissipation during work. In practical work, its operating life is almost unlimited, it can be switched frequently, and the timing of switching can be precisely controlled. Therefore, smooth input and removal without transition process can be realized, and the dynamic response time is only 0.01-0.02 s. This is an ideal switch...

0 Preface Single-phase ground faults are the most common faults in power systems. When a single-phase earth fault occurs in a neutral point ungrounded network, it can be operated with a fault for 2 hours. However, if the capacitance to ground in the power grid is large (such as cable lines), a large arc will be formed at the grounding point, posing a threat to the safe operation of the power system. The arc suppression coil can be used to reliably extinguish the arc. The design scheme of the...
Industrial Router Crystal 3.2*2.5mm 3225 26M (26.000MHZ) 12PF 10PPM 20PPM 30PPM Photocoupler A light-controlled thyristor is a thyristor that is triggered by an optical signal or a photoelectric signal. Its symbol is shown in Figure 1. The characteristic of the light-controlled thyristor is that a photodiode is integrated in the gate region, and the trigger signal source is insulated from the main loop. The key point is that the trigger sensitivity is high. The trigger current of the gate of...
I. Introduction The three-phase thyristor bridge type semi-controlled rectifier circuit can control the DC output voltage of the rectifier circuit by changing the control angle of the trigger circuit of the thyristor under the condition that the AC power supply voltage is constant. The circuit is medium-sized. Rectifiers or applications that do not require reversible electric drag systems are more widely used. The traditional three-phase bridge half-controlled rectifier circuit requires three...
An explosion-proof energy-saving thyristor speed regulating device that can be used in mine battery locomotives has been successfully developed and put on the market in Hebei Hengshui Taichang Mine Electronic Equipment Factory. At present, most of China's mining battery locomotive speed control devices use resistor speed controllers. In the process of use, due to high energy consumption, poor safety and explosion performance, etc., it has brought many problems to the use of enterprises. It is...
