Urban distribution network underground cable joint fault detection equipment and method

Abstract

The invention discloses urban distribution network underground cable joint fault detection equipment comprising a first protection box, a second protection box, a connection rod and a probe rod; a cable fault tester is installed in the first protection box; a cable test signal generator is installed in the second protection box; a probe is fixed at the end part of the connection rod; a handle is fixed at one end of the probe rod in a threaded manner; and a protection mechanism is arranged on the probe rod. The invention also discloses a urban distribution network underground cable joint faultdetection method; through arranging the protection mechanism on the probe rod, the protection of the protection sleeve on the tip of the probe rod is increased, the tip is prevented from abrading thestorage bad and damaging the user mistakenly; dustproof mechanisms are arranged on both the probe rod jack and the probe jack, the joint can be fastened via the protection plate, and thus the joint can be fixed more firmly; the joint jack can be sealed via the matching of the protection plate, the movable post and the spring, so that the dustproof effect is achieved.

Description

technical field [0001] The invention belongs to the technical field of cable joint fault detection, and in particular relates to an underground cable joint fault detection device for an urban distribution network and a detection method for the device. Background technique [0002] The cable fault tester is commonly used for underground cable joint fault detection. It is suitable for measuring the precise location of faults such as broken wires, mixed wires (short circuit), and leakage of low-voltage power cables. It is a powerful tool for shortening fault finding time, improving work efficiency, and reducing the labor intensity of line maintenance personnel. Line inspection and repair personnel can also use it Used in line engineering acceptance and inspection of cable electrical characteristics. [0003] However, there are still some unreasonable factors in the existing urban distribution network underground cable joint fault detection equipment in use. The existing urban ...

AI Technical Summary

Problems solved by technology

[0006] The object of the present invention is to provide a kind of fault detection equipment and method for underground cable joints of urban distribution network, to solve the problem that the probe rod socket and the probe socket proposed in the above-mentioned background technology are not conducive to dust prevention due to lack of protection; Because one end is a pointed part, due to the lack of protection, there are hidden dangers that the pointed part will scratch the storage bag and accidentally injure the user
