DETAILED DESCRIPTION
[0028] In order to make the purpose, features and advantages of the utility model more obvious and easy to understand, the technical solutions in the utility model will be described clearly and completely below in combination with the drawings in the specific embodiments. Obviously, the embodiments described below are only part of the embodiments of the utility model, rather than all the embodiments. Based on the embodiments in the patent, all other embodiments obtained by those skilled in the art without creative labor belong to the scope of protection of the patent.
[0029] As shown in the figure, the positioning tool provided in the embodiment is mainly applied to the GIS horizontal quick grounding switch 1. The GIS horizontal quick grounding switch 1 is provided with a quick grounding transmission system device 2, and the quick grounding transmission system device 2 is provided with an outer flange 12. The quick grounding transmission system device 2 is connected with a contact seat assembly 3. Figures 1 to 5
[0030] Among the GIS gas insulated switchgear horizontal quick grounding switch 1, the contact seat assembly is a component composed of a contact seat body and a connecting part. The contact seat body is made of copper alloy with high conductivity, which is fixedly connected with the movable contact. The connecting part is used for electrically connecting the contact seat with the busbar of the GIS, so as to ensure that the current can be smoothly conducted through the grounding switch.
[0031] The positioning tool provided in the embodiment comprises a base 9 and an opening adjustment sleeve 4.
[0032] At the edge of the base 9, at least three through holes are uniformly distributed, and the split-limiting shaft 7 is installed in the through holes. The bottom of the base 9 is designed to be matched with the structure of the outer flange of the quick grounding transmission device 2 of the horizontal quick grounding switch 1, and the base 9 can be stably installed on the horizontal quick grounding switch 1 by inserting the split-limiting shaft 7 through the outer flange, and the base 9 is provided with a split-limiting seat 10, and an inner sleeve is rotatably connected inside the split-limiting seat 10, and a limiting hole 13 is arranged inside the inner sleeve, and the limiting hole 13 penetrates to the bottom of the base 9; and the transmission mechanism of the quick grounding transmission device 2 is inserted into the limiting hole through the outer flange 12.
[0033] The split-adjusting sleeve 4 of the embodiment is connected with the split-adjusting seat 11, and the split-adjusting seat 11 is provided with a positioning shaft 6 matched with the limiting hole of the split-limiting seat 10, so as to realize the accurate split positioning function. The cross section of the positioning shaft 6 is capsule-shaped, and the cross section of the limiting hole is a waist-shaped hole.
[0034] The split-adjusting sleeve 4 and the split-adjusting seat 11 of the embodiment are further provided with a limiting line 5, which is used to further ensure the accuracy and stability of the adjustment. The diameter of the split-adjusting sleeve 4 is greater than the diameter of the split-adjusting seat 11.
[0035] The bottom of the base 9 is further provided with a connecting disc 8, and four through holes are formed at the edge of the connecting disc 8, and the shape of the through holes is highly matched with the shape of the outer flange. This design can tightly connect the base 9 with the outer flange, and enhance the stability and reliability of the whole.
[0036] Based on the above-mentioned positioning tool, the connecting disc 8 at the bottom of the base 9 is aligned with the outer flange of the quick grounding transmission device 2 of the horizontal quick grounding switch 1, and the four through holes at the edge of the connecting disc 8 are completely overlapped with the corresponding hole positions on the outer flange.
[0037] The split-limiting shaft 7 is inserted through the through holes at the edge of the base 9 and the outer flange, so as to ensure that the base 9 is firmly installed on the quick grounding transmission device 2 and the position is accurate.
[0038] For the closing position marking, the operator manually and slowly controls the quick grounding transmission device 2 to perform the closing operation. When the quick grounding transmission device 2 accurately penetrates through the outer flange and enters the limiting hole of the split-limiting seat 10, the operation is immediately stopped. At this time, the position data of the quick grounding transmission device 2 relative to a certain fixed reference point on the outer flange is measured and recorded by using a measuring tool. At the same time, the closing position at this time is marked on the outer flange by using a marking pen.
[0039] For the opening adjustment and position marking, continue to manually operate the quick grounding transmission device 2 to perform the opening operation until the limit position is reached, i.e. the quick grounding transmission device 2 cannot move outward any more. Put the opening adjustment sleeve 4 into the limiting hole of the opening limiting seat 10 to ensure that the opening adjustment sleeve 4 is installed in place. Then, slowly rotate the opening adjustment sleeve 4 in the counterclockwise direction, while observing the limiting line 5 between the opening adjustment sleeve 4 and the opening adjustment seat 11. When the limiting line 5 is accurately aligned, immediately stop rotating the opening adjustment sleeve 4 to ensure the accuracy of the opening adjustment.
[0040] Again manually control the quick grounding transmission device 2 to perform the closing operation until the quick grounding transmission device 2 again accurately passes through the outer flange and penetrates into the limiting hole of the opening limiting seat 10. At this time, again use the measuring tool to measure and record the position data of the quick grounding transmission device 2 relative to the same fixed reference point on the outer flange, and mark the opening position at this time on the outer flange.
