Installing force device plus high-current switch many, volume weight is big, and the tank bracket with greater need for a kind of high intensity is supported.
Utility model content
This utility model is for solving above-mentioned technical problem for providing the heavy current low-voltage switch cabinet that a kind of temperature raises less, radiating efficiency is high.
For solving above-mentioned technical problem, the technical solution adopted in the utility model is:
A kind of heavy current low-voltage switch cabinet, including cabinet, air inlet fan, air-out fan, temperature sensor and controller, the quantity of described air inlet fan and air-out fan is two or more, described air-out fan is separately positioned on the top of cabinet and the top of cabinet, and described air inlet fan is arranged on the bottom of cabinet; Described temperature sensor is arranged in cabinet, and is connected with controller, and described controller is arranged in cabinet, and controller connects and control air inlet fan and air-out fan, and described cabinet is provided with two or more air vent.
This utility model provides the benefit that: when the load of switch increases time, when heat increase temperature reaches certain value, temperature sensor detects that cabinet internal temperature is too high, start fan running, outside air is sent in cabinet by air inlet fan, air in cabinet is sent in the external world by air-out fan, reaches the exchange of air, makes cabinet temperature decline; When the load of switch is little time, when electric current is less, relies on air vent gravity-flow ventilation, namely can meet design requirement, save again electric power energy.
As a kind of preferred structure of the present utility model, described cabinet includes main bus-bar and the earth lead of equidistant arrangement, and described main bus-bar supports beam by bus frame and bus and is arranged on cabinet, and described earth lead is connected with cabinet, and is arranged on the bottom of cabinet.
As a kind of preferred structure of the present utility model, described bus frame is thickness is that the epoxy plate of 35mm is made, and described bus supports beam to be thickness be the epoxy plate of 10mm and makes.
As a kind of preferred structure of the present utility model, the opposite side of the top of described cabinet, bottom and cabinet is equipped with air vent, and described air vent is all provided with filtering screen and shutter.
As a kind of preferred structure of the present utility model, described air inlet fan and be equipped with filtering screen on air-out fan.

Detailed description of the invention
By describing technology contents of the present utility model, structural feature in detail, being realized purpose and effect, below in conjunction with embodiment and coordinate accompanying drawing to be explained in detail.
Please with reference to Fig. 1, Fig. 2, Fig. 3, Fig. 4 and Fig. 5, known as shown in the figure, this utility model heavy current low-voltage switch cabinet includes cabinet 1, air inlet fan 2, air-out fan 3, temperature sensor 4 and controller 5, cabinet 1 adopts the C of modularization to splice, intensity is high, the width of cabinet, height, deeply can arbitrarily change, the quantity of air inlet fan 2 and air-out fan 3 is two or more, air-out fan 3 is separately positioned on the top of cabinet and the top of cabinet, and air inlet fan 2 is arranged on the bottom of cabinet; Temperature sensor 4 is arranged in cabinet 1, and is connected with controller 5, and controller 5 is arranged in cabinet, and controller 5 connects and control air inlet fan 2 and air-out fan 3, and cabinet 1 is provided with two or more air vent 6. The opposite side of the top of cabinet 1, bottom and cabinet 1 is equipped with air vent 6, and air vent 6 is all provided with filtering screen and shutter. Air inlet fan 2 and air-out fan 3 are equipped with filtering screen. Meet the high-protection level of cabinet 1 and prevent dust, insecticide etc. from entering cabinet 1. When the load of switch increases time, namely electric current increases so heat increases, when temperature reaches certain value, temperature sensor 4 detects that cabinet 1 internal temperature is too high, starting fan running, outside air is sent in cabinet 1 by air inlet fan 2, and the air in cabinet 1 is sent in the external world by air-out fan 3, reduce the purpose of in-cabinet temperature, make cabinet 1 temperature decline; When the load of switch is little time, when namely electric current is less, relies on air vent 6 gravity-flow ventilation offered, namely can meet design requirement, save again electric power energy.
Cabinet 1, by the C type skeleton of high intensity, couples together by strengthening plate; The skeleton of modularization, better the change width of cabinet, height, deep, be better combined. In order to prevent the generation of big electric current cabinet eddy current, cabinet 1 applies non-magnet material, cabinet 1 includes main bus bracket, in length and breadth beam, central post, mounting rail, conductor rail support, and main bus bracket, in length and breadth beam, central post, mounting rail, conductor rail support all adopt non-magnet material corrosion resistant plate to make. Cabinet 1 also includes main bus-bar and the earth lead of equidistant arrangement, and main bus-bar supports beam by bus frame and bus and is arranged on cabinet 1, and earth lead is connected with cabinet 1, and is arranged on the bottom of cabinet. Bus frame is thickness is that the epoxy plate of 35mm is made, and bus supports beam to be thickness be the epoxy plate of 10mm and makes.Bus frame and bus support beam and adopt epoxy plate processing cabinet 1, will not generate heat because producing nest stream, adopt the processing of epoxy plate designed, designed to also improve insulating supporting intensity, thus improving the dynamic stability of cabinet 1.
In use procedure, cabinet 1 adopts the C of modularization to splice as required, the width of cabinet 1, height, deeply can arbitrarily change; Parts in cabinet 1 adopt non-magnet material and epoxy plate to make as required, will not produce eddy current and cause cabinet 1 to generate heat. Being configured with temperature sensor 4 in cabinet 1, temperature sensor 4 is connected with controller 5, is used for controlling the switch of fan, the temperature controlled fan according to cabinet 1 reality. Under the premise not reducing cabinet degree of protection, accomplish good heat radiation, effectively reduce the temperature rise of high-current switch.
The foregoing is only embodiment of the present utility model; not thereby the scope of the claims of the present utility model is limited; every equivalent shapes utilizing this utility model description and accompanying drawing content to make or reconfiguration; or directly or indirectly it is used in other relevant technical fields, all in like manner include in scope of patent protection of the present utility model.
