Detection device for power line fault monitoring equipment

Abstract

The invention relates to the technical field of fault detection, in particular to a detection device for power line fault monitoring equipment, which comprises a cable, a connecting column is mountedat the bottom of the cable, a cutting ring is mounted on the surface of the connecting column, the axial section of the cutting ring is semicircular, and a connecting block is mounted at the bottom ofthe cutting ring. The connecting block is slidably connected to the interior of the connecting column, a threaded rod is installed in the connecting block, the threaded rod is in threaded connectionwith the connecting block, and the threaded rod is rotatably connected with the connecting column through a bearing. According to the cable cutting device, the cable is annularly cut, wire stripping is facilitated, the device is fixed to the cable, cutting is more convenient, fixing and cutting can be conducted according to cables of different sizes, the application range is wider, good market competitiveness is achieved, and the cable cutting device is worthy of recommendation.

[0002] Power line refers to the line used to transmit electric energy between power plants, substations and power users. It is an important part of the power supply system and is responsible for the task of transmitting and distributing electric energy. Users or electrical equipment are connected, and the conductor loop that transmits and distributes electrical energy from the power supply end (transformation, power distribution station) to the load end (electric energy user or electrical equipment). The power lines are divided into high-voltage lines and low-voltage lines. , High-voltage lines refer to power lines with a voltage of 1kV and above, low-voltage lines refer to power lines below 1kV, and some power lines from 1kV to 10kV or 35kV are called medium-voltage lines, and power lines from 35kV to 110kV or 220kV are called high-voltage lines Lines, and power lines above 220kV or 330kV are called ultra-high voltage lines. Power lines are divided into overhead lines, cable lines and indoor lines according to their structure. The basic requirements of power lines: safe and reliable power supply, convenient operation, flexible operation, Economical and conducive to development, power lines mainly include overhead lines, cable lines and workshop lines, etc., and their structural forms are different. Compared with cable lines, overhead lines have more advantages, such as low cost, less investment, and easy installation. Maintenance and repair are convenient, and it is easy to find and troubleshoot, so overhead lines are widely used in general factories, but overhead lines are directly affected by the atmosphere, vulnerable to lightning strikes and dirty air, and overhead lines occupy a certain amount of ground and space. It hinders traffic and viewing, so it is subject to certain restrictions. Modern factories tend to gradually reduce overhead lines and use cable lines. Compared with overhead lines, cable lines have disadvantages such as high cost, large investment, and inconvenient maintenance. It has the advantages of reliable operation, not easily affected by the outside world, no need to erect electric poles, does not occupy the ground, and does not hinder the view. Especially in places with corrosive gases, flammable and explosive places, it is not suitable to erect overhead lines, and only cables can be laid Lines, in modern factories and cities, cable lines have been more and more widely used, the structure of cable lines is mainly composed of cables, cable heads and end caps, cable brackets and cable clamps, etc.

[0003] However, it is more troublesome to troubleshoot the fault. It is necessary to strip the wire and find the broken place, but the cable is easy to shake, making it difficult to strip the wire.
