Composition of the medium-frequency power supply cabinet for a medium-frequency induction furnace
Medium-frequency power supply cabinet, medium-frequency furnace, thyristor
1. Medium-frequency power supply cabinet
The power supply enclosure is manufactured using a special process, featuring an aesthetically pleasing design, a rational modular structure, high rigidity, excellent dust resistance, and appropriate ventilation and heat dissipation measures. The enclosure color is computer gray. Its unique dual-door structure separates low-voltage control circuits from high-voltage circuits, effectively preventing electromagnetic interference and further enhancing the overall system’s operational reliability.
Comprehensive protection features:
Main circuit short-circuit protection; main circuit phase-loss protection; high-grid-voltage protection; low-grid-voltage protection;
Low cooling water pressure protection; thyristor overvoltage protection; thyristor overcurrent protection;
High-rate-of-rise current protection for inverter thyristors; insufficient commutation time protection for inverter thyristors;
Insufficient reverse blocking voltage time protection for thyristor inverters.
2. Connecting copper busbar
The copper busbars inside the intermediate-frequency power supply are all tinned to ensure reliable connections and prevent oxidation caused by moisture. All corner busbars are neatly connected with smooth, rounded arcs, replacing the previous process in which several busbars were joined using bolts. This unique busbar fabrication process reduces the number of connection points, making the equipment more reliable and aesthetically pleasing.
3. Thyristor
The thyristor is the core component of medium-frequency power supplies and also one of the more expensive components. Party B must select a manufacturer with strong technical capabilities, stringent manufacturing processes, and comprehensive testing methods, and require that manufacturer to: 115 Perform junction temperature testing at ℃ and issue the test results. During component assembly, match and install components according to the tested parameters. Use products from Xiangfan Taiji Power Electronics Factory.
4. Smoothing reactor
The silicon steel laminations used in the smoothing reactor are cold-rolled with high permeability, and the copper tubes are... T2 Extruded copper tubing, wrapped with high-strength mica tape. H Class insulation. To reduce the operating noise of the filter reactor, the silicon steel sheets are subjected to a special clamping process.
