Description

TECHNICAL FIELD

[0001] The utility model discloses electric control equipment field, specifically related to a kind of electric control room incoming line system wiring device. BACKGROUND

[0002] Electric control room is a kind of facility specially used for controlling and protecting electrical equipment, which usually contains switching equipment, measuring instruments, protective electrical appliances and auxiliary equipment. These devices are assembled in closed or semi-closed metal cabinets according to electrical wiring requirements, in order to meet the needs of normal operation of power system, and to ensure safety during maintenance, to avoid harm to the person and surrounding equipment.

[0003] In the process of internal wiring at the outgoing end of the electric control room, the space is usually small and cannot meet the requirement of simultaneously connecting a large number of cables to the same layer busbar, i.e. the electrical requirement of a high load busbar and a large number of cables (usually 6-8) to be connected. In actual work, if simultaneous connection cannot be met, the usual solution is to use separate busbars to connect each other, which has the advantage of saving busbars, but requires bending the cables to connect with the busbars. Although the cables are separated, the bending angle of the cables is too large, which easily causes stress and hardening of the cables, and the concentration of cables easily causes overheating, thereby reducing the service life of the outgoing end system of the electric control room. The contact area between the wire nose and the copper bar is small, which easily causes overload. Moreover, the separated busbar connection method easily causes wear of the cables during actual connection, and the separate connection of the upper and lower layers causes the length of some cables to be inconsistent, which makes it difficult to disconnect and increases the difficulty of statistics. In addition, there is a method of connecting by splitting the combined double parallel busbars, but this connection method has high design requirements for the housing body and is only suitable for housing bodies with large outgoing end space, and is not suitable for housing bodies with small outgoing end area, which has great limitations.
