Description

A low-voltage integrated distribution box

technical field

The utility model relates to the technical field of electric power system distribution equipment, in particular to a low-voltage integrated distribution box.

Background technique

The low-voltage integrated distribution box is installed at the outlet of the low-voltage side of the transformer in the distribution station area or at the branch of the line. It is used to cut off the power supply in a short time after the protection line fails to ensure the safe operation of the distribution line. . Since the low-voltage integrated distribution box operates outdoors and is too tightly sealed, not only is it exposed to direct sunlight to generate high temperature, but also the internal low-voltage electrical appliances will also generate heat, resulting in excessively high temperature inside the box, especially in high-temperature seasons in midsummer. The temperature will reach above 60°C, and the temperature at this time greatly exceeds the ambient temperature of these electrical appliances, so failures will occur due to overheating of the electrical components in the distribution box. Although, both sides of the box body of the existing low-voltage integrated distribution box are provided with ventilation windows for heat dissipation, the heat dissipation effect is very unsatisfactory, and the problem of excessively high temperature inside the box body still cannot be solved.

Contents of the invention

In order to solve the above problems, the purpose of this utility model is to provide a low-voltage integrated distribution box with simple structure and good heat dissipation effect.

In order to realize the above-mentioned purpose of the invention, the utility model adopts the following technical solutions:

A low-voltage integrated distribution box, which includes a box body with doors at the front and back, shutters are provided on the front door and the back door, and a heat dissipation device is installed in the box body. The heat dissipation device includes a temperature sensor, a controller and a fan. The fan is installed In the interlayer on the top of the box body, the temperature sensor is connected to the controller, and the signal output end of the controller is connected to the control circuit of the fan.

Due to the adoption of the above-mentioned technical scheme, the utility model has the following advantages:

The low-voltage integrated distribution box can enhance the heat dissipation effect of the box and effectively reduce the temperature inside the box by setting louvers on the front and rear doors of the box and installing a fan on the top of the box to achieve the best operation of electrical components in the box. Environmental temperature, avoiding the failure of electrical components due to overheating, and prolonging the service life of electrical components.

Detailed ways

Below by accompanying drawing, the utility model is described in further detail.

As shown in Figures 1 and 2, the low-voltage integrated distribution box includes a box body 1 with doors at the front and back of the box body, shutters 3 are provided on the front door 2 and the rear door, and a heat dissipation device is installed in the box body, and the heat dissipation device includes The temperature sensor, the controller and the fan are installed in the interlayer on the top of the box, the temperature sensor is connected to the controller, and the signal output end of the controller is connected to the control circuit of the fan.

The temperature sensor detects the temperature in the distribution box. When the temperature in the box exceeds the preset temperature value, the controller outputs a signal, and the fan starts to forcibly discharge the heat through the louvers on the front door and the back door to dissipate heat from the box.
