Embodiment Construction
[0033] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some, not all, embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.
[0034] see Figure 1-6 , the present invention provides a technical solution:
[0035] A method for overlapping large-current multi-split busbars, comprising the following steps:
[0036] S1. Assemble the fixed plate 1 and the main busbar 2. The fixed plate 1 can be made of insulating material, and a backing plate 3 is arranged between them. The two sides of the backing plate 3 are closely connected with the fixed plate 1 and the main busbar 2 respectively. ...

The invention discloses a large-current multi-spliced busbar lap joint method and device. The method comprises the following steps: S3, branch busbars are placed in grooves of groove drawing cushion blocks respectively; S4, a gasket is placed on the side, away from the groove-drawing cushion block, of the branch busbar, so a protruding part of the gasket is made to be close to the branch busbar, and the branch busbar makes contact with horizontal parts on two sides of the protruding part of the gasket respectively; S5, an end piece is placed on the side, away from the protruding part, of the gasket; S6, crimping screws are arranged in a through groove of a fixed plate, a through groove of a base plate, a through groove of the main busbar, a through hole of the groove-drawing cushion block,a mounting hole of the gasket and a mounting groove of the end piece in a penetrating manner. According to the large-current multi-spliced busbar lap joint method provided by the invention, scribing,size correction and punching are not needed, the built-in groove-drawing cushion block can meet the requirement of simultaneous lap joint of a plurality of branch busbars and main busbar, the temperature rise can be effectively reduced, the requirements of dynamic stability and thermal stability are met, and the large-current multi-spliced busbar lap joint method is very worthy of popularizationand application.
Description
technical field [0001] The invention relates to the technical field of busbar lapping, in particular to a large-current multi-split busbar lapping method and a device thereof. Background technique [0002] Large current circuits are often encountered in high and low voltage complete cabinets, that is, power supply circuits of 2000A to 6300A. For these power supply circuits, two-piece, three-piece, and four-piece copper bars are often used, especially for the lap connection of main busbars and branch busbars. , It is necessary to mark the line, check the size and punch holes, and the process is more troublesome. For this reason, a method of improving the process is proposed. [0003] In the prior art, the application number is "201821778323.3", a non-drilling busbar lapping device, which includes a guide plate and a fixing frame. There are installation holes on the side, and the guide plate is set on the inner side of the fixed frame. The two sides of the guide plate are pro...
