Universal connection device between emergency power supply vehicle and low-voltage overhead wire and its application

Abstract

The invention discloses a universal type connecting device for an emergency power supply vehicle and a low-voltage overhead line. A connecting device is arranged between the emergency power supply vehicle and the low-voltage overhead line. One end of the connecting device is connected with the emergency power supply vehicle, the other end is connected with the low-voltage overhead line, and circuit connection with an isolation protection function is established between the emergency power supply vehicle and the low-voltage overhead line. The connecting device comprises an insulated cross arm assembly and a switch cabinet. An emergency power supply of the emergency power supply vehicle firstly passes through the switch cabinet and then is connected with the insulated cross arm assembly through a pole climbing cable connected with the switch cabinet, and the pole climbing cable is connected with a circuit of the low-voltage overhead line through the insulated cross arm assembly. The universal type connecting device is applicable to the fields of providing emergency protection, power generation and on-load transformer replacement work for customers along the low-voltage overhead line in a transformer area. The connection is reliable. A power supply effect is stable. The security is good. The universal type connecting device also can match the performance of novel working projects such as replacement of a transformer and a drop fuse under load.

Description

technical field [0001] The invention relates to an auxiliary device for repairing and maintaining electric equipment and related applications thereof, in particular to a general-purpose connecting device for connecting an emergency power supply vehicle with a low-voltage overhead wire and related applications. Background technique [0002] At present, a special vehicle-emergency power supply vehicle is often used in the field of power equipment repair and maintenance in the power system. The emergency power supply vehicle can continue to supply power when the power equipment is repaired and maintained, and prevent regional power outages. , its role is self-evident. [0003] During the normal use of the emergency power supply vehicle in the prior art, the output terminal of the generator set passes through the integrated control terminal and reserves the outlet cable interface of the emergency power supply vehicle. Connect the terminal power supply of the power distribution ...

AI Technical Summary

Problems solved by technology

[0009] If the customer uses a dedicated transformer for power supply and belongs to a single customer, during the power outage period of transformer replacement, the emergency power supply vehicle can still be used to provide emergency power protection in a point-to-point power supply mode. When there are a large number of residential customers, the emergency power supply vehicle will not be able to provide emergency power protection by means of point-to-point power supply. Similarly, when replacing the 10KV drop-out fuse in the pole substation area, it will also cause power outages for customers along the low-voltage line
