Abstract

The application relates to a high-voltage cable branch box, which relates to the field of power system equipment. It includes a box body, and a ventilation device is installed in the box body. The ventilation device includes a temperature and humidity sensor, and the temperature and humidity sensor is installed in the box body. The temperature and humidity sensor is electrically connected to a controller, the box is connected with a first air inlet pipe and a first air outlet pipe, an air inlet fan is installed in the first air inlet pipe, an air outlet fan is installed in the first air outlet pipe, and the air inlet The motors of the fan and the air outlet fan are electrically connected to the controller. The present application has the effect of reducing the possibility of humid air causing harm to the inside of the high-voltage cable branch box.

Description

technical field [0001] The present application relates to the field of power system equipment, in particular to a high-voltage cable branch box. Background technique [0002] In the 10kV distribution network cable project of the power system, it has become a big problem to replace a large number of branches in the overhead line of the original distribution network with an economical, reliable and easy-to-maintain wiring method, and the appearance of the cable branch box has completely solved the problem. This problem has become the first choice for distribution network cable engineering. Its simple, convenient and flexible connection combination makes it replace the ring main unit in some occasions, and is widely used in commercial centers, industrial parks and urban dense areas. [0003] In the related art, the high-voltage cable branch connection equipment is located in the cable branch box, and most of the high-voltage cable branch boxes are arranged in outdoor places. ...
