The invention discloses a switch device capable of fast changing over induction furnace bodies. The switch device comprises a rotating electricity-conducting plate and is characterized by further comprising two first electricity-conducting plates and a second electricity-conducting plate, wherein the first electricity-conducting plates are respectively connected with the corresponding induction furnace bodies, and the second electricity-conducting plate is connected with a variable-frequency power source. The rotating electricity-conducting plate capable of rotating around the second electricity-conducting plate and being communicated with the two first electricity-conducting plates respectively is arranged on the second electricity-conducting plate. A water-cooled tube is arranged inside the rotating electricity-conducting plate, and water-cooled tubes are arranged in the first electricity-conducting tubes. The switch device solves the problems that a ventilation method for cooling is adopted in a high-power power switch in the prior art, the high-power switch is poor in heat dissipation effect, large in heat dissipation system size, noisy, high in manufacturing cost and, and electricity leakage accidents can be caused easily due to poor in insulating property. The switch device capable of fast changing over the induction furnace bodies is provided, wherein the switch device is simple in structure, good in insulating property, strong in heat dissipation effect and operability, high in safe and reliable coefficient, low in manufacturing operation cost and low in floor space.
Description
technical field [0001] The invention relates to a switch used in the electrical field, in particular to a switch device for quickly switching induction furnace bodies. Background technique [0002] At present, all high-power switching power supplies must solve the cooling problem of the heat generated by power devices due to loss during the inverter and rectification process, so as to ensure that the power devices work in an allowable temperature environment. When used in various mechanical equipment, if effective heat dissipation cannot be carried out, the service life of high-power power switches will be seriously affected, and even large mechanical equipment cannot work normally, which will bring great inconvenience to users. At present, most of the cooling of the high-power power switch housing is done by ventilation, including natural air cooling and forced air cooling: [0003] 1) Natural air cooling: transfer the heat of the power device to the copper or aluminum rad...
