Technical field
The utility model relates to a kind of mounting structure of induction furnace water-cooled Electric heating capacitance group, belongs to induction furnace equipment technical field.
Background technology
Induction furnace is a kind of method utilizing electromagnetic induction phenomenon heating of metal, applied to widely Metal Melting, diathermanous, quenching and Surface heat-treatent.Induction furnace natural power factor very low (0.03-0.6), if they are directly accessed power supply, will consume a large amount of reactive power, very uneconomical.So modern induction heating power is often furnished with the compensation condenser group designed for improving circuit power factor.Building-out capacitor in induction furnace belongs to capacitor for electric induction heating system, and generally its rated voltage is not more than 3.6kV, frequency 40-24000Hz.Water flowing is needed to cool.Water pipe is extremely connected with one of shell and capacitor, outer casing electrification during operation.Capacitor banks is arranged in power cabinet.
Traditional mounting structure is that capacitor is arranged on the frame plate of bottom, frame plate adopts insulation offset plate and intermediate frequency power supply cabinet to insulate, Electric heating capacitance insulation against ground only relies on the insulation board on base plate, insulation board is aging all can make Electric heating capacitance over the ground or each other flashover occur with conductive particle that is that be scattered, if insulation breakdown will make major loop ground, have an accident.Adopt air insulation between every block capacitor, personal distance requires more than 20mm.The shortcoming of such assembly structure is: if spacing is not enough, do not reach safe distance, and insulation breakdown flashover electric discharge between shell easily occurs; And spacing strengthens, can make to conflux the corresponding growth of busbar, cabinet strengthens, and investment increases, and power loss is very large again; Simultaneously; even if spacing is enough; because field working conditions causes conduction dust and dust due to electromagnetic principle very easily gathering deposition around capacitor; often can there is conduction flashover fault in onsite application process to occur; equipment itself is damaged; electric discharge, arcing simultaneously all very easily produces personal injury accident, and security risk can not be estimated.
Utility model content
Technical problem to be solved in the utility model is to provide a kind of mounting structure of induction furnace water-cooled Electric heating capacitance group, this mounting structure can reduce spacing, reduce power loss, raise the efficiency, reduce investment, can safety requirements be met again, stop the generation of flashover, ensure device security stable operation.
The technical scheme solved the problems of the technologies described above is:
A kind of mounting structure of induction furnace water-cooled Electric heating capacitance group, it comprises multiple insulation column and the vertical isolated insulation plate of polylith, multiple insulation column is arranged on the bottom insulation plate in power cabinet respectively, capacitor for electric induction heating system is installed in the upper surface of insulation column, installed vertical isolated insulation plate between every two capacitor for electric induction heating system, the lower end of vertical isolated insulation plate is connected with bottom insulation plate.
The mounting structure of above-mentioned induction furnace water-cooled Electric heating capacitance group, the both sides of capacitor for electric induction heating system group have the fixed connecting plate of two horizontal positioned respectively, fixed connecting plate is connected with capacitor for electric induction heating system with nut by connecting bolt, there is draw-in groove the side of fixed connecting plate, vertical isolated insulation plate between draw-in groove with capacitor for electric induction heating system is relative, and the both sides of vertical isolated insulation plate are embedded in draw-in groove.
The mounting structure of above-mentioned induction furnace water-cooled Electric heating capacitance group, the upper end of described vertical partition insulation board higher than capacitor for electric induction heating system wiring porcelain vase terminal, and lower than the busbar that confluxes.
The beneficial effects of the utility model are:
The utility model installs insulation column additional between bottom insulation plate and capacitor for electric induction heating system, each capacitor for electric induction heating system independent suspension is insulated, there is flashover in that has stopped that capacitor for electric induction heating system produces because of the impact of bottom insulation plate aging and electro-conductive dust, prevents the major loop ground that insulation breakdown causes over the ground or each other; Increase vertical isolated insulation plate between capacitor for electric induction heating system, solve capacitor for electric induction heating system side insulation problem, avoid the flashover occurred because spacing between capacitor for electric induction heating system is not enough, make the spacing between capacitor for electric induction heating system to reduce to 5mm.The utility model structure is simple, insulation effect is good, not only can stop the generation of flashover, ensure device security stable operation, avoid the generation of personal safety accident, the spacing between capacitor for electric induction heating system can be reduced again, reduce power loss, raise the efficiency, reduce investment, there is significant economic benefit.
