Rapid power supply connection device for 10KV overhead power distribution line

Abstract

The invention discloses a rapid power supply connection device for a 10KV overhead power distribution line. The connection device is fixedly installed on a specific electric pole of the 10kV overheadpower distribution line passing power supply guarantee evaluation argumentation; through the 10kV power distribution line installed with the device, rapid access power supply of a medium-voltage mobile emergency power supply vehicle can be realized at any time by only one comprehensive small team or group; a rapid connection plug of a cable of the medium-voltage movable emergency power supply vehicle is matched with a connection assembly of the device; the power distribution line installed with the device can be rapidly connected to adjacent other power distribution lines installed with the device through equipment such as bypass cables, bypass load switches and the like, thereby realizing transfer power supply; and a rapid connection plug of a cable of the bypass equipment is matched withthe connection assembly of the device.

Description

technical field [0001] The invention relates to a fast power supply connection device for a 10KV overhead power distribution line. Background technique [0002] Power supply is currently the most prominent public security demand, and it is imperative to accelerate the development and manufacture of power supply guarantee emergency industrial equipment. [0003] At present, the emergency power supply is directly connected to the overhead line of the 10kV distribution network through a 10kV cable. There are two ways to directly connect the power supply through the 10kV cable: power-off work connection or live work connection. The method of directly connecting to the overhead line of the distribution network through a 10kV cable mainly has the following disadvantages: [0004] 1. When the power supply is connected through a 10kV cable through a power outage operation, it is necessary to interrupt the power supply of the line user at the access point; [0005] 2. When the pow...

AI Technical Summary

Problems solved by technology

[0004] 1. When the power supply is connected through a 10kV cable through a power outage operation, it is necessary to interrupt the power supply of the line user at the access point;

[0005] 2. When the power supply is connected through live work through a 10kV cable, special types of live workers are required to carry out the connection, and the operation safety risk is great;

[0006] 3. When carrying out access work, the layout of cables, vehicles, and bypass equipment on site is complicated, and there are many access workflows;

[0007] 4. When carrying out the connection work, it involves professional cooperation of switching operation, electrical test, live work, generator parallel disconnection, and bypass operation, which involves a lot of manpower and material resources, difficult coordination and low work efficiency;

[0008] 5. From planning access to on-site task completion, the time requirement is more than 2 days, and the work is time-consuming;

[0009] 6. Influenced by factors such as difficulty in access, multi-type professional collaboration, and time-consuming, the operators have low willingness to organize emergency power supply work, high-value equipment assets are trapped, and power supply services are affected at the same time
