Totally-enclosed refractory flame-retardant flexible branch bus

Abstract

The invention discloses a totally-enclosed refractory flame-retardant flexible branch bus. The branch bus comprises a main flexible bus and an auxiliary flexible bus, wherein, a conductive band of the auxiliary flexible bus is inserted into the main flexible bus to be fixedly connected with a conductive band of the main bus through a fastening fixture; the fastening fixture and the conductive bands as well as the conductive bands connected together are respectively separated from each other by insulating partition plates; the joint of the auxiliary flexible bus and the main flexible bus is poured with synthetic resin; the conductive bands are in structures formed by laminating metal sheets with high electric conductivity, and the thickness of the metal sheets is 0.1mm-1mm; insulating layers and mica tapes are sequentially wrapped on the conductive bands of the main bus and the auxiliary bus, and glass tapes with high flame resistance and insulating sheaths are also integrally wrapped on the conductive bands sequentially; and the fastening fixture is formed by punching a high-quality steel plate. The totally-enclosed refractory flame-retardant flexible branch bus has the advantagesthat the conductive bands of the two flexible buses are more firmly connected together through the fastening fixture, thus saving conductor metal materials and improving energizing capability.

Description

technical field [0001] The technical field of power transmission and distribution equipment of the present invention, in particular, relates to a fully enclosed fire-resistant and flame-retardant branch flexible busbar. Background technique [0002] The busbar has the function of collecting and distributing electric power, and the busbar is very common in the current power distribution and transmission equipment. Usually in the power station, the electric energy output by the generator, transformer or rectifier is transmitted to each device or power consumer through the busbar. The existing busbar structure is to fix the conductive bars in the busway, and make the busbar shunt connection through direct connection, L-shaped connection, T-shaped connection and other methods. Because the bus bar is cut with conductive bars, the contact area is limited, which affects the transmission of power, wastes metal materials, and the manufacturing process of the shunt connection is comp...

AI Technical Summary

Problems solved by technology

Because the busbar is cut with conductive bars, the contact area is limited, which affects the transmission of power, wastes metal materials, and the manufacturing process of the shunt connection is complicated and inconvenient to install.

Joints are prone to loosening when subjected to vibration

In addition, the biggest defect of the traditional busbar is that it cannot change the shape at will according to the change of the use environment.
