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.

Embodiment Construction
[0013] The technical solutions of the present invention will be described in detail below with reference to the accompanying drawings.
[0014] Refer to the attached figure 1 It is a schematic cross-sectional view of a fully enclosed fire-resistant and flame-retardant branched soft busbar. The branched busbar includes a main soft busbar 1 and an auxiliary soft busbar 2. After removing the insulating layer 5 and mica tape 6 from the conductive tape 3 of the auxiliary soft busbar The fastening clip 4 is connected and fixed with the conductive strip of the main soft bus bar with the insulating layer and the mica tape removed. The fastening clip and the conductive strip and the conductive strips connected to each other are separated by an insulating partition 41. The fastening clip is a It is stamped and formed with high-quality steel plate to ensure the connection of the conductive strip is firm and stable, and then the fastening clip and the connection of the main and auxiliary ...

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 advantages that 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 present invention is in the technical field of power transmission and distribution equipment, in particular to a fully enclosed fire-resistant and flame-retardant branched soft busbar. Background technique [0002] The busbar has the function of collecting and distributing power, and it is very common in the current distribution and transmission equipment. Usually in the power station, the electric energy output by the generator, transformer or rectifier is transmitted to each equipment or electricity user through the busbar. In the existing busbar structure, the conductive bar is fixed in the busbar slot, and the busbar shunt connection is made by means of direct connection, L-type connection, T-type connection, etc. Because the busbar uses a conductive row, the contact area is limited, which affects the transmission of power, wastes metal materials, and the production process of the shunt connection is complicated and the installation is inconve...
