1) Fault phenomenon: Frequent burnout of the thyristor original, after replacement, burned out Analysis: Refer to fault E) for additional introductions as follows: a. When the thyristor is turned off in reverse, the instantaneous glitch voltage subjected to the reverse voltage is too high, and the RC absorption is checked. b. The load is reduced excerpt …

The basic working principle of the thyristor intermediate frequency power supply is to rectify the 50 Hz industrial frequency AC current into DC through a three-phase bridge rectifier circuit. Circuit diagra:

The structure of the medium frequency iron coreless induction furnace (see Figure 1) mainly consists of three parts: 1. Induction coil (wound by water-cooled copper tube) 2. Crucible (usually made of refractory materials) 3. Furnace charge (can (for fragments of various metal materials) The basic principle of the medium frequency ironless induction furnace is a excerpt …

Transformer is a device that uses the principle of electromagnetic induction to change AC voltage. Its main components are primary coil, secondary coil and iron core (magnetic core). The main functions are: voltage conversion, current conversion, impedance conversion, isolation, voltage stabilization (magnetic saturation transformer), etc.The transformer combined with our intermediate frequency furnace includes:1. Power transformer, excerpt …

Thyristor is commonly known as silicon controlled thyristor. The difference between a thyristor and a diode is that it can control on and off. A represents the anode, K represents the cathode, and G represents the control electrode.

Induction forging furnaces continue to drive the market in the foundry industry. The design and operation of induction forges continue to improve as smelters look for newer and more cost-effective methods for steel melting. According to the World Steel Association, global production of steel in 2018 stood at 1.81 billion tonnes. The increase in production excerpt …
