Abstract

The invention relates to a busbar and insulation support protection system of a distribution box, which comprises a switchover busbar module group and a single-row branch busbar module group. The switchover busbar module group comprises a switchover busbar shield base, a switchover busbar shield bottom cover, switchover busbars and outgoing line busbars; the switchover busbar shield base and the switchover busbar shield bottom cover are linked with each other through a clipping hook and clipping groove structure to form a switchover busbar shield; the inner surface of the switchover busbar shield bottom cover is provided with three or four busbar grooves; the switchover busbars are arranged in each busbar groove in sequence; and the two ends of each switchover busbar are both provided with a screw hole used for connecting the switchover busbar with other components. The branch busbar module group comprises a large branch busbar bracket, a shield module, a small branch busbar bracket, a Pc protection plate and branch busbars; the right ends of three or four branch busbars are clamped in a horizontal groove of the small branch busbar bracket; and the left ends of the three or four branch busbars are clipped in a horizontal groove of the large branch busbar bracket. The system has the advantages of compact structure, reasonable layout, good insulation performance and high security.

Description

technical field [0001] The invention relates to a busbar of a distribution box and an insulation support protection system, belonging to the field of power distribution. Background technique [0002] Due to the small internal space of the distribution box, there have always been difficult technical problems in terms of insulation support and safety protection when only busbars are used for layout. At present, the electrical connection design of the distribution box is still based on wires or some copper bars The form of the wire is the main form, and its disadvantages are that the insulation performance is poor, the support effect is not good, and there are great safety hazards in use. Contents of the invention [0003] The purpose of the present invention is to provide a distribution box busbar and an insulation support protection system to improve its safety performance. [0004] The distribution box busbar and insulation support protection system according to the prese...
