Problems solved by technology

[0003] The currently designed connection device is not only larger and more complex in structure, but also has a complicated connection with the connection unit, which is not conducive to operation. In order to avoid excessive carrying capacity, the main conductor of the connection device needs to be fully considered when setting The current-carrying capacity, so that the entire device cannot be fully utilized in terms of materials, and the weight of the connection device cannot be better reduced

Embodiment 1

[0040] A device for connecting slotted bus bars in cabinets to switch circuit breakers, such as figure 2 As shown, it includes a plurality of insulating modules 1 with installation grooves and conductive plug-in bars 2. The insulating module 1 press-fits the conductive plug-in bars 2 into the installation grooves to form a busbar insertion channel 9. The outer casing 5 used for protection and reinforcement on the insulation formwork, the insulating module 1 sets the conductive plug-in row 2 through the outer casing 5, and the insulating partitions for isolation are arranged between the plug-in channels 9 of each phase. plate 8.

[0041] Specifically, such as image 3 As shown, the insulation module 1 includes a half "worker" for the end and a "worker" shape insulation module for the conductive plug-in row 2, and the upper and lower inner walls of the "worker" are symmetrically arranged for the conductive plug-in row Positioned installation groove, the insulation module 1 pr...

Abstract

The invention discloses a connecting device, in particular a connecting device for a busbar channel and switch circuit breaker in switchgear and belongs to the technical field of distribution switchgear. The device comprises multiple insulation modules provided with mounting grooves and conductive plug strips, wherein the insulation modules press the conductive plug strips in the mounting grooves to form busbar plug channels, the device further comprises outer protective cases which sleeve the insulation modules and are used for protection and reinforcement, the insulation modules sleeve the conductive plug strips through the outer protective cases, and insulation partitions for isolation are arranged among plug channels. With the adoption of the connecting device, the problem that circuits for electrical connection in the switchgear are complex is solved, so that inner connecting units are modular, the connecting device is easy to assemble and free from maintenance due to adoption of the plug manner, the structure in the switchgear is effectively optimized, and the cost is reduced.

Description

technical field [0001] The invention relates to a connection device, in particular to a connection device for a grooved busbar in a cabinet and a switch circuit breaker, and belongs to the technical field of power distribution switch cabinet devices.
