Abstract
The utility model discloses a low -voltage cabinet with automatically function of dispelling heat includes the cabinet body to and the cabinet door of setting on the cabinet body, cabinet body both sides are provided with the vent, the cabinet is internal be provided with with the filtration that the vent is relative, the filtration includes braced frame and sets up first filter layer and second filter layer in the braced frame, the cabinet body still is provided with the radiating fin into electrical component, the fan is installed to the fin below, the fan is connected with the control by temperature change circuit. When the temperature reaches the temperature detect switch threshold value in the low -voltage cabinet, automatically open the fan operation, dispel the heat to subassembly in the cabinet, play the thermolysis promptly, again can the energy saving, improved fan life, and setting up of filtration makes the low -voltage cabinet have dustproof function.
Description
Technical field
The utility model relates to electric cabinet technical field, particularly relates to a kind of low pressure cabinet with automatic dissipating heat function.
Background technology
Low pressure cabinet, i.e. low-tension switch cabinet, it is applicable to the industries such as power station, oil, chemical industry, metallurgy, weaving, Highrise buildings, as the use of transmission of electricity, distribution and electric energy conversion, the electric component in cabinet has a large amount of electric charges to flow through, and therefore the switching cabinet of prior art all can install heat abstractor, but the fan of the switching cabinet with heat abstractor of prior art opens throughout the year, therefore, waste is serious, and fan is short for work-ing life; In addition, existing low pressure cabinet does not have dust reduction capability, and dust etc. can enter low pressure cabinet by ventilation opening.
Practical novel content
(1) technical problem solved
The purpose of this utility model to be overcome above-mentioned shortcoming exactly, it is intended to provides a kind of low pressure cabinet with automatic dissipating heat function.
(2) technical scheme
For achieving the above object, the low pressure cabinet with automatic dissipating heat function of the present utility model, comprises cabinet, and the cabinet door being arranged on cabinet; Described cabinet both sides are provided with ventilation opening, are provided with the filtration relative with described ventilation opening in described cabinet, and described filtration comprises support frame and the first filtering layer of being arranged in described support frame and the 2nd filtering layer; Described cabinet also arranges the radiator element of promising electric component heat radiation; Being provided with fan below described radiator element, described fan is connected with temperature control circuit.
Further, described temperature control circuit comprises temperature controlled switch, current limliting resistance and power supply.
Further, described power supply, temperature controlled switch, current limliting resistance and fan are electrically connected successively.
Further, described ventilation opening is skewed.
Further, temperature controlled switch is KSD301 temperature controlled switch, and described KSD301 temperature controlled switch is by bimetallic strip as the temperature module, and when temperature reaches threshold value, bimetallic strip closes conducting.
Further, it is provided with active carbon layer and pottery core layer in described first filtering layer and the 2nd filtering layer.
(3) useful effect
Compared with prior art, the technical solution of the utility model has the following advantages: when low pressure in-cabinet temperature reaches temperature controlled switch threshold value, automatically opens fan and runs, cabinet inner assembly is dispelled the heat, namely thermolysis is played, again can save energy, it is to increase fan work-ing life; And it being provided with the filtration of corresponding ventilation opening so that low pressure cabinet has dust reduction capability.

Fig. 2 is the temperature control circuit module map of the low pressure cabinet with automatic dissipating heat function of the utility model embodiment;
Fig. 3 is the structural representation of ventilation opening and filtration in Fig. 1;
In figure: 1 is cabinet; 2 is ventilation opening; 3 is radiator element; 4 is fan; 5 is temperature control circuit; 6 is electric component; 7 is filtration; 8 is support frame; 9 is the first filtering layer; 10 is the 2nd filtering layer.
Embodiment
Below in conjunction with drawings and Examples, embodiment of the present utility model is described in further detail. Following examples are for illustration of the utility model, but are not used for limiting scope of the present utility model.
As shown in Figures 1 to 3, the low pressure cabinet with automatic dissipating heat function of the present utility model, comprises cabinet 1, and the cabinet door being arranged on cabinet 1. Cabinet 1 both sides are provided with ventilation opening 2, and ventilation opening 2 is in skewed, and object is that can prevent water droplet or steam from flowing backwards enters in cabinet 1, affects electric component 6 in cabinet.
The filtration 7 relative with ventilation opening 2 it is provided with in cabinet 1, filtration 7 comprises support frame 8 and the first filtering layer 9 being arranged in support frame 8 and the 2nd filtering layer 10, it is provided with active carbon layer and pottery core layer in this first filtering layer 9 and the 2nd filtering layer 10, make the outside air etc. just to enter cabinet 1 after double medium filtration, it is to increase the dust-proof effect of low pressure cabinet.
Cabinet 1 also arranges the radiator element 3 of promising electric component 6 heat radiation, is provided with fan 4 below radiator element 3, and fan 4 is connected with temperature control circuit 5, and temperature control circuit 5 comprises temperature controlled switch K1, current limliting resistance R1 and power supply.
As shown in Figure 2, power supply, temperature controlled switch K1, current limliting resistance R1 and fan 4 are electrically connected successively. Temperature controlled switch K1 is KSD301 temperature controlled switch, and KSD301 temperature controlled switch is by bimetallic strip as the temperature module, and when temperature reaches threshold value, bimetallic strip closes conducting. The installation position of temperature controlled switch K1 is generally close on radiator element 3, the temperature of radiator element 3 can be sensed so fast, when temperature reaches temperature controlled switch conducting temperature, the electric loop conducting of fan, starting fan, for electric component dispels the heat, below temperature drops back to temperature controlled switch conducting temperature, the electric loop of fan is closed, and fan is out of service, and so forth.
The low pressure cabinet with automatic dissipating heat function of the present utility model possesses the function of automatic heat radiation, has both played thermolysis, again can save energy, it is to increase fan work-ing life, moreover it is possible to dust-proof.
In sum, above-mentioned enforcement mode is not restricted enforcement mode of the present utility model, the modification that the technician of all this areas carries out on the basis of flesh and blood of the present utility model or equivalent deformation, all at technology category of the present utility model.
