0.4 kV uninterrupted power operation rapid plugging device

Abstract

The invention discloses a 0.4 kV uninterrupted power operation quick plugging and unplugging device, which comprises a cable connection terminal and a base connection fitting, wherein a connecting hole connected with a cable is formed in the bottom of the cable connecting end of the cable connecting terminal, a watchband contact finger is arranged on the side wall of the fitting connecting end, aterminal head insulating sheath is arranged on the outer side of the cable connecting terminal, locking clamping grooves are formed in the fitting connecting end and the surface of the side wall of the terminal head insulating sheath on the outer side of the fitting connecting end respectively, the terminal connecting end of the base connecting fitting is provided with a connecting hole matched with the fitting connecting end and the watchband contact finger, the outer side of the base connecting fitting is provided with a base insulating sheath, the side wall of the base insulating sheath isprovided with a self-locking mechanism matched with the locking clamping groove, and the outer side of the self-locking mechanism is provided with an unlocking sliding sleeve capable of sliding frontand back. The insulation degree of overhead line jumper wire equipment can be increased, and it is ensured that 0.4 kv uninterrupted power distribution line construction is safe and reliable.

Description

technical field [0001] The invention relates to a 0.4kV fast plug-in device for non-power-off operation used in the field of electric power engineering. Background technique [0002] With the accelerated development of the urban construction process and the deepening of the insulation engineering transformation of the overhead lines of the urban power grid, people have higher and higher requirements for planned maintenance and emergency repair time, less power outages or even no power outages. Among them, when the scope of operation is mainly in the densely populated area of ​​the city center, the power outage operation will cause very serious inconvenience to urban residents and bring great economic losses to the power grid company. Especially for 0.4kV users, the requirements for power supply reliability are higher. The non-stop operation of 0.4kV power distribution overhead lines has become an important way to ensure the safe and reliable operation of the power grid, redu...

AI Technical Summary

Problems solved by technology

At present, the jumper connection of the overhead lines in the urban power grid adopts a bolt-type connection structure, without insulation measures, and the construction can only be carried out after a power failure. There may be safety hazards in the operation without power failure, which may cause unnecessary personal safety accidents, and the bolt-type structure in There are problems such as inconvenient construction and long time during the operation without power failure
