Description

A cable terminal connection device

technical field

The utility model relates to a cable terminal connection device.

Background technique

In recent years, with the transformation of the urban network and the construction of new rural electrification, the 1OKV power distribution and transmission grid has all achieved standardization and insulation operations. In order to ensure the safe and stable operation of the distribution low-voltage power grid. These power distribution equipment need to be maintained regularly. The maintenance work includes refueling of transformers, gear shifting, installation of anti-theft locks, replacement of knife switches in JP (distribution transformer integrated power distribution cabinet), replacement of meter transformers, AC contactors, air switch etc. In the actual construction operation, first cut off the power of the branch line, and then disassemble the transformer and JP (distribution transformer integrated distribution cabinet) cabinet, because the traditional distribution network line is exposed steel-cored aluminum stranded wire as the transmission wire of the distribution network , The exposed wire can be connected to the grounding point at any place, and many electrical contacts in the city network distribution station area are exposed, which is relatively convenient to connect to the grounding point. But with the construction requirements of the national smart grid. The distribution network transmission lines require insulated wires, and all electrical contacts of the substation are insulated. It is required that all electrical contacts should be insulated and covered; it is required to install grounding wires and conduct electrical inspections on the high and low voltage sides in the distribution area. If the distribution network is completely insulated and transformed, there will be no place to connect the ground wire, and there will be no place to find an electrical inspection point. Make ground wire hooking become loaded down with trivial details, maintenance is extremely inconvenient. As a result, the work intensity of construction and maintenance personnel is high, the difficulty of construction and maintenance is high, and the working hours are long. In addition, there are usually multiple transformers on the 1OKV line. When multiple transformers fail at the same time, it will cause a large area of power failure and cause serious economic losses.

Utility model content

In view of the above problems, the utility model aims to provide a cable terminal connection device.

A cable terminal wiring device, including a bracket, a fastening nut, a junction box, an umbrella shed, a grounding ring, a wiring ring, an electrical contact insulating sheath, a drainage line card, an insulating mandrel, a lightning rod, a ground stake, a ground wire, and a support One end is installed with a lightning rod, and the other end is installed on the ground pile. There is a ground wire inside the ground pile. The bracket and the junction box are fixed by fastening nuts. The bracket inside the junction box is equipped with an insulating silicone umbrella skirt, and multiple umbrella skirts are parallel to each other. Distribution, the inside of the bracket is provided with insulating mandrels, the junction box is provided with multiple outlet holes, the bracket is provided with electrical contact insulating sheaths, and the electrical contact insulating sheaths are equipped with drainage line clips and wiring rings, and the bottom of the bracket is set Grounding ring, the grounding ring connects the lightning rod and the ground wire through the wire.

The cables are wound on the umbrella skirt in the junction box and pulled out from the outlet hole. In addition, the insulating sheaths of the electrical contacts can be red, green and yellow in order to facilitate phase separation and improve the speed and safety of circuit maintenance.

The utility model comprises a bracket, a junction box, an electric contact insulating sheath, an umbrella skirt and an insulating mandrel, and the electric contact insulating sheath is provided with a drainage line clip, a wiring ring and a grounding ring. And the umbrella skirt and insulating mandrel are designed as an integrated structure.
