Description

Technical Field

[0001] The utility model relates to the field of busbar transfer bar installation structures, in particular to an installation structure of a box shell for a busbar transfer bar. Background Art

[0002] The busbar transfer row is also called a transfer box or a plug-in box. It is composed of a shell, a circuit breaker, pins and a protector. Its function is to convert the bus duct to the cable, and it is also a device that outputs current from the bus. The power is transmitted from the bus duct through the pins of the transfer box to the circuit breaker in the box, and from the circuit breaker through the protector and the cable to the electrical equipment. At present, when installing the busbar transfer row, the pins of the busbar transfer row need to be inserted into the sockets of the bus duct, that is, the busbar transfer row and the bus duct are fitted together. In order to prevent the pins of the busbar transfer row from coming out of the sockets of the bus duct, an installation structure is needed to fix the two.

[0003] At present, the installation structure of the busbar transfer bar is simple, generally two metal sheet locks are installed at the bottom of the busbar transfer bar shell, and the metal sheet locks are clamped to the shell protrusions of the bus duct with bolts. Although there is a certain fixing effect, due to the weight of the busbar transfer bar shell, this installation structure has poor stability and can easily cause the metal sheet locks to twist and deform due to weight, causing the busbar transfer bar to fall from the bus duct.
