[0001] The utility model relates to the technical field of furnace changer switches, in particular to an electric furnace changer switch. Background Art

[0002] Induction furnaces use the principle of electromagnetic induction to heat and melt metals. This method is an ideal heating process and has been widely used in metal smelting, welding, surface hardening and other processing and heat treatment processes. The configuration mode of induction furnaces in the prior art is "one power and two furnaces", that is, one set of power supply device and two furnace bodies. The two furnace bodies are one for use and one for backup. One is connected to the power supply system for online work, and the other is maintained for backup and works online in a cycle.

[0003] However, the induction furnace in the prior art still has certain deficiencies when controlling furnace change. The prior art generally adopts a manually operated jack to push the furnace change or a hydraulically pushed furnace change. However, during the operation, the efficiency of manual operation may be relatively low, and the work efficiency is slow. The hydraulic pushing operation may easily cause pressure leakage problems, which may cause unstable connections between busbar groups and easy contact sparking. The safety of use needs to be further improved. Utility Model Content
