Abstract

The invention discloses an underground multi-directional branch line protection device for electric power, which comprises an external hollow shell. The invention is used for underground pre-buried electric wires, which can withstand the upper pressure. At the same time, the use of solid desiccant can dry and dehumidify the internal humid air, reduce the influence of humid air on the branch line, and reduce the occurrence of leakage. , and, in actual work, it has a certain buffering and anti-shock ability, which can reduce the loosening effect of external vibration on the wire connection part, and effectively protect the wires. Moreover, the device has a pipe hole-mounted sealing ring sealing mechanism, which can protect The internal dry air will not flow together. In addition, the device has a circular pipe installation type wire bending guide mechanism to prevent the occurrence of internal damage caused by excessive bending of the wire. In addition, the device has a helical spring support type gas limit connection The mechanism reduces the impact on the wire connection part.

Description

technical field [0001] The invention relates to the technical field of electric power installation, in particular to an underground multi-directional branch line protection device for electric power. Background technique [0002] At present, in electric power places, some wires are pre-buried underground for power transmission, and in actual work, the bus needs to be divided into lines, but the existing line protection devices have poor capabilities and relatively large limitations.
