A moisture-proof grounding box

Abstract

The invention discloses a grounding box capable of moisture prevention. The grounding box comprises a wrapping box and a cable clamping seat, wherein the cable clamping seat is used for connecting a grounding circuit and is arranged in the box, the box comprises a box body and a box cover, one side of the box cover is hinged with the box body and covers the box body, a drying device is arranged on the inner wall of the box body and comprises a drying box and a drying pipe, the drying box is arranged on the lower side wall of the box body, and the drying pipe is arranged on the right side wall, the upper side wall and the left side wall of the box body in an encircling way. With the arrangement of the drying box and the drying pipe of the drying device, a drying effect on air in the box body of the grounding box can be developed, and a series of problems caused by air humidity in the box body are prevented.

Description

technical field [0001] The present invention relates to a kind of electric equipment, more specifically relates to a kind of moisture-proof grounding box. Background technique [0002] Cable grounding boxes are mostly used in 35kv and above single-core cable grounding systems. Due to poor sealing of cable grounding boxes and poor control of construction links, current cable grounding boxes are often induced by factors such as overcurrent, moisture, and product quality. Faults. In recent years, the faults of the cable grounding box have occurred frequently, which has caused the power grid to be shut down for maintenance, and at the same time brought great economic losses to power supply customers. [0003] The existing moisture-proof methods of the box are all reflected by increasing the isolation and sealing between the box and the outside world. The better the sealing of the box, the stronger its moisture-proof ability. However, in the ground box, it is necessary to leave a...

[0002] Cable grounding boxes are mostly used in 35kv and above single-core cable grounding systems. Due to poor sealing of cable grounding boxes and poor control of construction links, current cable grounding boxes are often induced by factors such as overcurrent, moisture, and product quality. Faults. In recent years, the faults of the cable grounding box have occurred frequently, which has caused the power grid to be shut down for maintenance, and at the same time brought great economic losses to the power supply customers.

[0003] The existing moisture-proof methods of the box are all reflected by increasing the isolation and sealing between the box and the outside world. The better the sealing of the box, the stronger its moisture-proof ability. However, in the ground box, it is necessary to leave a The through hole through which the cable passes, so its airtightness cannot achieve the effect of the existing sealed box, and when the cable grounding box is powered on, the connection copper bars and copper terminals in the grounding box will be damaged due to the current. It will emit a lot of heat, so it is easy to have an accident in a completely sealed environment, so it is very necessary to use a new type of moisture-proof structure to increase the moisture-proof performance of the grounding box
