For achieving the above object, the utility model provides following technical scheme:
A kind of self cool high-voltage alternating metal enclosed switchgear, comprises breaker chamber, main bus bar room, cable vault and control room.The pressure release passage cover plate at circuit breaker top installs top heat-pipe radiator additional, and the heat pipe shape of top heat-pipe radiator is I shape, is welded on pressure relief plate.
As further program of the utility model: install breaker thermal tube radiator at the quiet leading-out terminal of circuit breaker, breaker thermal tube radiator designs for integral type, and its structure is plate fin formula structure.
As the utility model further scheme: install contact arm heat-pipe radiator on the contact arm of circuit breaker additional.
As the utility model further scheme: the metal partion (metp) between breaker chamber and main bus bar room is installed dividing plate heat-pipe radiator.
As the utility model further scheme: longitudinally install contact box mounting plate heat-pipe radiator at contact box mounting plate.
As the utility model further scheme: install fixed contact bus radiator on the bus that fixed contact is drawn.
Compared with prior art, the beneficial effects of the utility model are: the utility model utilizes the heat transfer element of this high thermal conductivity of heat pipe, by evaporation and the transferring heat that condenses of working medium in Totally enclosed vacuum shell, there is high thermal conductivity and good isothermal, the heat transfer area of cold and hot both sides can change arbitrarily, can remotely transferring, temperature controllable.On the integrally-built basis not changing switch cubicle, be only to be transformed by the heat concentrated part at switch cubicle, improve heat conductivility, significantly improve the parameter level of high-pressure vacuum breaker rated current, well solve problem of temperature rise.The utility model utilizes the high heat transfer performance of heat pipe, and the heat transfer that can dynamic/static contact contact in large-current vacuum arc extinguishing chamber be produced rapidly, in air, makes its temperature rise value control in the scope of national Specification.The utility model is changed little to original equipment, cost is lower, and it is convenient to implement, and feasibility is good.
