A kind of high-current switch
Technical field
The utility model relates to a kind of electric power facility, particularly a kind of switch cubicle.
Background technology
Existing middle high-tension switch cabinet, because its structural design compactness, the electric power components and parts are more, the switch cubicle of big electric current particularly, and its temperature rise was very high when it used, for the switch cubicle of 4000A, its temperature rise electric current reaches 4400A, has surpassed the rated current of switch cubicle like this, makes that easily components and parts burn out after long-time the use, cause damage, even cause the accident.
Summary of the invention
The high-current switch that provides a kind of temperature rise lower is provided the utility model purpose.
The utility model comprises cabinet, in described cabinet, be divided into the high pressure basement by dividing plate, bus-bar room, breaker chamber, described high pressure basement, bus-bar room, breaker chamber is arranged to preceding successively by the back, top and high pressure basement on described cabinet, bus-bar room, the corresponding pressure relief plate of breaker chamber is the corrugated plating that has some through holes, described bus-bar room is provided with lower clapboard, be provided with spacing between the bottom surface of described bus-bar room lower clapboard and cabinet, described spacing forms passage and is communicated with the high pressure basement, side lower part is provided with preceding Xiamen before the described cabinet, described preceding Xiamen is provided with the blinds fenestra, be provided with the blinds fenestra at described bus-bar room lower clapboard, in described passage, axial flow blower be set; Described breaker chamber is provided with the breaker chamber lower clapboard, at described breaker chamber lower clapboard the blinds fenestra is set, and below described breaker chamber lower clapboard axial flow blower is set; The madial wall of described bus-bar room is arranged to black.
The utility model is by arranging the blinds fenestra respectively on the preceding Xiamen of cabinet, bus-bar room lower clapboard, breaker chamber underlay screen, and by axial flow blower to the heat radiation of drying of each chamber; The ripple pressure relief plate at top has the effect of wind-guiding, and corrugated plating has also increased radiating rate simultaneously; Bus-bar room madial wall painted black can effectively strengthen the heat loss through radiation ability of switch cubicle; By above-mentioned effective heat radiation setting, the temperature rise of this high-current switch that it effectively reduces.

Embodiment
As Fig. 1, shown in 2, this high-current switch comprises cabinet 1, in cabinet 1, be divided into high pressure basement 2 by dividing plate, bus-bar room 3, breaker chamber 4, high pressure basement 2, bus-bar room 3, breaker chamber 4 is arranged to preceding successively by the back, top and high pressure basement 2 on cabinet 1, bus-bar room 3, breaker chamber 4 corresponding pressure relief plates are the corrugated plating 6 that has some through holes, bus-bar room is provided with lower clapboard 5, be provided with spacing 7 between the bottom surface of bus-bar room lower clapboard 5 and cabinet, spacing 7 forms path 10 and is communicated with high pressure basement 2, side lower part is provided with preceding Xiamen 8 before the cabinet 1, preceding Xiamen 8 is provided with blinds fenestra 9, be provided with blinds fenestra 11 at bus-bar room lower clapboard 5, axial flow blower 12 is set in path 10; Breaker chamber 4 is provided with breaker chamber lower clapboard 13, at breaker chamber lower clapboard 13 blinds fenestra 14 is set, and axial flow blower 15 is set below breaker chamber lower clapboard 13; The madial wall of bus-bar room 3 is arranged to black.
This switch cubicle inner assembly adopts the stainless steel manufacturing as contact box mounting panel 16, current transformer mounting panel 17 etc., adopts stainless steel bolt to install, and has avoided like this causing the rising of cabinet temperature and the consumption of electric energy because of electromagnetic induction eddy current.
