Abstract

The utility model discloses a low-voltage comprehensive power distribution box, which comprises a box body, wherein doors are arranged on front side and rear side of the box body; both the front door and the rear door are provided with shutters; a heat dissipation device is arranged in the box body and comprises a temperature sensor, a controller and a fan; the fan is arranged in a sandwich layer on the top of the box body; the temperature sensor is connected with the controller; and a signal output end of the controller is connected with a control circuit of the fan. The power distribution box has a simple structure and a good heat dissipation effect, and temperature in the box body can be effectively reduced.

Description

A kind of low-voltage comprehensive distribution box
Technical field
The utility model relates to electric power system controller switching equipment technical field, particularly relates to a kind of low-voltage comprehensive distribution box.
Background technology
Low-voltage comprehensive distribution box is installed in the bifurcation of step down side exit, power distribution station or circuit, after being used for protection circuit and breaking down, cuts off the electricity supply immediately at short notice, ensures a kind of switchgear of distribution line safe operation.Because low-voltage comprehensive distribution box is in outdoor operation, sealed tight, the direct irradiation that not only is subjected to sunlight produces high temperature, and inner low-voltage electrical apparatus operation also can produce heat, cause the box house temperature too high, particularly midsummer high temperature season, the box house temperature can reach more than 60 ℃, at this moment temperature has substantially exceeded the ambient temperature of these electrical equipment, therefore can take place because of the overheated fault that causes of electric elements in the distribution box.Though the casing both sides of existing low-voltage comprehensive distribution box are provided with ventilating window, be used for heat radiation, radiating effect is very undesirable, still can not solve the too high problem of box house temperature.
Summary of the invention
For addressing the above problem, the purpose of this utility model provides a kind of low-voltage comprehensive distribution box of simple in structure, good heat dissipation effect.
For achieving the above object, the utility model adopts following technical scheme:
A kind of low-voltage comprehensive distribution box, it comprises casing, door is arranged before and after the casing, be equipped with shutter on Qianmen and the back door, heat abstractor is installed in the casing, and described heat abstractor comprises temperature sensor, controller and blower fan, and blower fan is installed in the interlayer of casing top, temperature sensor is connected with controller, and the signal output part of controller is connected with the control circuit of blower fan.
Owing to adopt aforesaid technical scheme, the utlity model has following superiority:
This low-voltage comprehensive distribution box, it is by offering shutter at the forward and backward door of casing, and at casing top installation blower fan, can strengthen the radiating effect of casing, effectively reduce the temperature of box house, to reach the ambient temperature of electric elements operation in the casing, avoid occurring electric elements because of the overheated phenomenon that causes fault, prolong the useful life of electric elements.
Description of drawings
Fig. 1 is the schematic perspective view of the utility model low-voltage comprehensive distribution box;
Fig. 2 is the module diagram of the heat abstractor of the utility model low-voltage comprehensive distribution box;
Among the figure: the 1-casing; The 2-Qianmen; The 3-shutter.
Embodiment
Below by accompanying drawing the utility model is described in further detail.
As shown in Figure 1, 2, this low-voltage comprehensive distribution box, it comprises casing 1, before and after the casing door is arranged, be equipped with shutter 3 on Qianmen 2 and the back door, heat abstractor is installed in the casing, described heat abstractor comprises temperature sensor, controller and blower fan, blower fan is installed in the interlayer of casing top, and temperature sensor is connected with controller, and the signal output part of controller is connected with the control circuit of blower fan.
Temperature sensor detects the temperature in the distribution box body, when the temperature in the casing surpasses preset temperature value, and controller output signal, blower fan is opened, and by force heat is discharged by the shutter on Qianmen and the back door, so that the casing heat radiation.
