Problems solved by technology
[0002] Existing high-voltage gas-insulated load switches are generally assembled in a welded frame. Due to the high heat in the welding process, the deformation of the frame is difficult to control, and sometimes the deformation of the frame is too large to be able to Install the switch element in place at one time, and have to manually correct the installation position many times, which is time-consuming and labor-intensive, and it is difficult to guarantee production efficiency and product quality

Embodiment Construction
[0018] The present invention will be described in further detail below in conjunction with accompanying drawing embodiment:
[0019] figure 1 , figure 2 and image 3 The shown assembly process method of the load switch includes the following steps:
[0020] A. Pre-installed static cutter head parts: install the static cutter head 1 vertically on the upper insulating beam 2 through the fastening end with a round head nut;
[0021] B. Pre-installed moving knife parts: install the moving knife bus bar 3 vertically on the lower insulating beam 4, and then evenly apply a layer of high temperature resistant conductive paste with a thickness of about 0.1mm on the concave spherical surface of the moving knife bus bar 3 , and then install the convex surface of the moving knife rod 6 on the concave surface of the moving knife bus bar 3;
[0022] C. Pre-install the ground cutter part including the rotating shaft: install the grounding cutter head 7 on the U-shaped groove after passi...

The invention discloses a load switch assembly technology method which includes the following steps of: A, preassembling a static tool bit part, B, preassembling a movable cutter part, C, preassembling a ground cutter part which includes a rotating shaft, D, fastening a switch back board and a switch front board, and beforehand fastening the preassembling static tool bit part, the preassembling movable cutter part and the preassembling ground cutter part with the rotating shaft on the switch back board one by one and then fastening on the switch front board, E, connecting movable cutter rods and the rotating shaft, arranging one end of a connecting rod between the two movable cutter rods and connecting the other end of the connecting rod with the rotating shaft, F, arranging an arc suppression coil, fastening the arc suppression coil on the static tool bit, adjusting the distance between the movable cutter and a static cutter to be 10 millimeters and then adjusting the distance between the movable cutter and an arc tongue of the arc suppression coil to be from 6 millimeters to 8 millimeters, G, arranging an isolation cover and arranging a nylon bar which is provided with the isolation cover in a penetrating mode on the switch back board and the switch front board. Compared with the prior art, the load switch assembly technology method solves the problems that the existing load switch assembly technology method is low in production efficiency and homogeneity of products and the like.
Description
technical field [0001] The invention relates to the technical field of manufacturing power transmission and distribution equipment in a power system, in particular to an assembly process method of a load switch. Background technique [0002] Existing high-voltage gas-insulated load switches are generally assembled in a welded frame. Due to the high heat in the welding process, the deformation of the frame is difficult to control, and sometimes the deformation of the frame is too large to be able to Once the switch element is installed in place, the installation position has to be corrected manually many times, which is time-consuming and labor-intensive, and it is difficult to guarantee production efficiency and product quality. Contents of the invention [0003] The purpose of the present invention is to provide a load switch assembly process method capable of ensuring production efficiency and product quality. [0004] In order to solve the above problems, the techn...
