Multifunctional quick conversion connecting assembly for power generation car cable

Abstract

The invention belongs to the technical field of electrical connection and relates to a multifunctional rapid conversion connection assembly for a generator car cable. The assembly comprises a copper nose connection device, a low-voltage overhead line rapid connection device and a coupler conversion device; the copper nose connection device comprises a first internal flexible cable, copper noses, a telescopic insulation structure and a first coupler connecting end, wherein the telescopic insulation structure is used for preventing adjacent copper noses from making contact with each other to cause short circuit; the low-voltage overhead line rapid connection device comprises a second internal flexible cable, a current guide wire clamp, an adjusting structure connected with the current guide wire clamp, and a second coupler connecting end; and the coupler conversion device is used for conversion butt joint when male and female couplers for laying cables with couplers are not matched with each other. With the multifunctional quick conversion connecting assembly of the invention adopted, a generator car can be effectively and quickly connected to a user low-voltage power distribution system, and the stability of power supply guaranteeing work is improved.

Description

technical field [0001] The present invention relates to the technical field of electrical connection, and more specifically, relates to a multifunctional quick-change connection assembly for cables of a generator car. Background technique [0002] In recent years, priority has been given to uninterrupted power operations in infrastructure projects, emergency repairs, and daily work. At the same time, with the needs of national construction and development, there are more and more large-scale cultural and political meetings, followed by this important activity Therefore, the generator car plays a very important role as a temporary power source. [0003] The daily work process of ensuring power supply is mainly driven by the generator car to the site to connect to the low-voltage power distribution system of the user to achieve reliable power supply on the low-voltage side of the user. A very critical step is how to connect the generator car to the low-voltage system of the us...

AI Technical Summary

Problems solved by technology

[0004] (1) When the location of the generator car is far away from the connected transformer, it is necessary to lay multiple sections of flexible cables, which may cause a mismatch between the front and rear cables and require re-laying, resulting in the inability of the generator car to be connected quickly, which is time-consuming and labor-intensive;

[0005] (2) When the cable of the generator car is used to connect to the load side, the types of load side connected include: low-voltage cabinet copper bars, and spare switch terminals, etc., and the cables of the generator car use copper lugs as cable terminals. When using, due to The distance between the three-phase terminals of some low-voltage cabinets is very close. Due to the narrow space, there may be a two-phase short circuit after the copper nose terminal is connected, and the copper nose is live and exposed, and there is a risk of personal electric shock. It is also difficult to use insulating tape at this time. Package, poor operability and low safety performance;

[0006] (3) When there is no low-voltage distribution box, low-voltage cabinet or low-voltage distribution box on the low-voltage load side of the low-voltage station area when using a generator car to connect to the low-voltage station area, you can choose to connect to the low-voltage overhead line; when using copper nose When the terminal is connected to the low-voltage overhead line, there may be no obvious access point, the connection is time-consuming and labor-intensive, and there are potential safety hazards;

[0007] Therefore, there are many problems in the current access method of power generation vehicles, which not only wastes a lot of manpower and material resources, but also has potential safety hazards, and cannot meet the high requirements of power supply guarantee work.
