Description

Bypass cable entry aids for cable terminations

technical field

The utility model relates to a bypass cable access auxiliary device applied to a cable terminal.

Background technique

(1) The current domestic economy is developing rapidly, the construction of first-class distribution network is deepening, the overhead line is in the ground, and the number of ring network cabinets is increasing. Today, ring network cabinets and box transformers are essential and important equipment in the power system distribution network , but if the ring network cabinet or box transformer cabinet or switch fails, it needs to be powered off and repaired, maintained or replaced. (2) Due to its small footprint, high power supply reliability and small maintenance workload, cable lines are becoming more and more popular in distribution networks, but there are also problems such as long maintenance time and difficult fault finding , which greatly increases the time for repairing faults and seriously affects the reliability of power supply. (3) When cables, ring network cabinets and box transformer cabinets fail, for some important loads, long-term power outage maintenance will have negative impacts on economy, politics, culture, life safety and many other aspects. (4) Due to the popular use of cables and the increase in the number of ring network cabinets, more and more cable terminals in the distribution network are applied to equipment such as box transformers and ring network cabinets.

Contents of the invention

The purpose of this utility model is to design a bypass cable access auxiliary device applied to cable terminals, which can quickly and safely complete the work of isolating the faulty switch of the ring network cabinet, and greatly reduce the number of faulty switches in the ring network cabinet due to power failure. The power outage time caused by the switch can quickly restore the power consumption of residential users affected by the fault.

The technical solution adopted by the utility model to solve the technical problem is: the bypass cable access auxiliary device applied to the cable terminal includes two parts, the connector and the bypass cable, the connector is composed of an insulating sleeve and a conductive joint, and the conductive joint is installed In the insulating sleeve, one end of the conductive joint protrudes from the insulating sleeve, the other end of the conductive joint is encapsulated in the insulating sleeve by a plug, and the bypass cable is inserted into the insulating sleeve to connect the conductive joint.

Wherein, a sheath is installed outside the insulating sheath.

The beneficial effects of the utility model are: 1. The structure is simple, the cost is low, the operation is convenient, and the operation is stable, so that it can quickly and safely isolate the fault interval or the faulty cable in the ring network cabinet, and restore the power consumption in time; 2. When the user does not stop power supply In the case of a fault, the power failure maintenance is carried out. The device has good economy, practicability and universality, and significantly improves the work efficiency.
