Description
Technical field
This utility model relates to electrical equipment, a kind of low-tension switch cabinet cooling system that can be used for low-tension switch cabinet.
Background technology
Switch cubicle is a kind of electrical equipment, and its Main Function is to carry out generating electricity in power system, transmit electricity, during distribution and electric energy conversion, carry out folding, control and protect electrical equipment.In general, the parts in switch cubicle mainly have the modular units such as chopper, disconnecting switch, on-load switch, operating mechanism, transformer and various protection devices, and these elements are arranged according to difference subregion in switch cubicle of function and effect and install.
But, in the prior art, it is configured in any case and arranges, each modular unit the most all can produce more heat transfer, if and these heats do not guide temperature build in discharge will cause switch cubicle and rise, affect the normal work of each modular unit, aging equipment, reduce service life of equipment.For these reasons, the most traditional switch cubicle is all to arrange louvre on sidewall, utilizes free convection to dispel the heat, but this radiating mode radiating effect is limited, DeGrain；Also the mode having external air-conditioning or aerator carries out active heat removal, but this mode is only applicable to the switch cubicle that volume is bigger, and for the low-tension switch cabinet of small size, its use cost is the highest, serious waste of resources.
Utility model content
This utility model is solved the technical problem that to be to provide a kind of low-tension switch cabinet cooling system, to solve the shortcoming in above-mentioned background technology.
This utility model is solved the technical problem that and is realized by the following technical solutions:
A kind of low-tension switch cabinet cooling system, including switch cabinet body and installing plate, described switch cabinet body is double-decker, and its outer layer is steel structure panel, internal layer is one layer of heat dissipation ceramic plate with some through holes, and leaves the gap of 30mm ~ 50mm between steel structure panel and heat dissipation ceramic plate with holes；And each modular unit being arranged in switch cubicle is separated by installing plate, described installing plate includes insulation board and is molded over two blocks of APC heat sinks of insulation board both sides.
In this utility model, the thickness of described heat dissipation ceramic plate is 8 ~ 12mm, and steel structure panel thickness is more than 8mm.
In this utility model, one layer of epoxy resin layer and layer of metal fabric wire side is also formed outside heat dissipation ceramic plate with holes, metal fabric wire side is encapsulated between epoxy resin layer and heat dissipation ceramic plate with holes, and the through hole on heat dissipation ceramic plate is through metal fabric wire side and epoxy resin layer.
In this utility model, described heat dissipation ceramic plate with holes being evenly equipped with the circular thermal vias that some pore sizes differ, the pore size of these thermal vias is 20 ~ 50mm.
In this utility model, the both sides steel structure panel of described cabinet has convection current air-vent.
In this utility model, also including temperature sensor, temperature sensor is arranged on the corner location in cabinet, and temperature measuring scope is-10 DEG C ~ 80 DEG C, higher than measurement range value then by alarm device early warning.
Beneficial effect: this utility model simple in construction, easy to make, heat radiation and insulating properties are superior, are difficult to corrosion, and be readily transported and dismount, integrated level height, easy-to-connect, interfere little between different function units simultaneously, protective capacities is strong, and can effectively cut operating costs.
Accompanying drawing explanation
Fig. 1 is the schematic diagram of this utility model preferred embodiment.
Fig. 2 is the detailed schematic of part A of the present utility model.
Wherein: 1, switch cabinet body；2, installing plate；3, modular unit installing space；4, steel structure panel；5, epoxy resin layer；6, metal fabric wire side；7, heat dissipation ceramic plate；8, thermal vias；9, convection current air-vent；10, APC heat sink；11, insulation board.
Detailed description of the invention
For the technological means making this utility model realize, creation characteristic, reach purpose and be easy to understand with effect, below in conjunction with being specifically illustrating, this utility model is expanded on further.
See the preferred embodiment of a kind of low-tension switch cabinet cooling system of Fig. 1, Fig. 2, in the present embodiment, including switch cabinet body 1, in switch cabinet body 1, be separated out different modular unit installing spaces 3 by the installing plate 2 of detachable combination.
In the present embodiment, switch cabinet body 1 is double-decker, the steel structure panel that thickness is 8mm 4 including outer layer, and the composite plate of internal layer, the gap of 40mm is left between steel structure panel 4 and composite plate, and composite plate includes being positioned at the heat dissipation ceramic plate 7 that thickness is 8mm of inner side, and on heat dissipation ceramic plate 7, form metal fabric wire side 6 and epoxy resin layer 5 successively.Gluing molding between heat dissipation ceramic plate 7, metal fabric wire side 6 and epoxy resin layer 5, and on its face, it is evenly equipped with the circular thermal vias 8 that some pore sizes differ, and the pore size of these thermal vias 8 is 20 ~ 50mm.Then having convection current air-vent 9 on steel structure panel 4, convection current air-vent 9 acts on jointly with thermal vias 8, can be effectively improved the radiating efficiency of cabinet.
In the present embodiment, installing plate then includes insulation board 11 and is molded over two blocks of APC heat sinks 10 of insulation board 11 both sides.On the other hand installing plate, and can the temperature of effectively average modules unit installing space 3 to be conveniently used for insulation.It addition, the most also include temperature sensor, temperature sensor is arranged on the corner location in cabinet, and temperature measuring scope is-10 DEG C ~ 80 DEG C, higher than measurement range value then by alarm device early warning.
