Description

Technical Field

[0001] The utility model relates to the technical field of GIS isolating switches, in particular to a stroke detection device for a GIS isolating switch. Background Art

[0002] 110kV GIS disconnectors typically use a design that combines an operating mechanism with a contact mechanism. However, during actual operation, failures in the operating mechanism or transmission components can cause the disconnector to not open or close properly, or the grounding switch contacts to not disconnect. This can frequently lead to serious electrical accidents, posing a significant threat to the safe and stable operation of the power supply system.

[0003] Since electrical operators cannot accurately monitor the travel position of the disconnector contacts when operating the GIS disconnector, it is difficult to avoid electrical accidents caused by inadequate contact travel. Currently, operators mainly verify the travel of the disconnector by marking lines on the contact shaft. Although this method can determine the travel of the disconnector, the lines may disappear after a period of time due to the influence of the environment on outdoor GIS. This requires operators to mark lines repeatedly, which increases the workload. Sometimes, this method cannot even monitor the travel of the switch contacts. Utility Model Content

DETAILED DESCRIPTION

[0021] The technical solutions in the embodiments of the present invention will be described clearly and completely below with reference to the accompanying drawings in the embodiments of the present invention.

[0022] The utility model provides a technical solution: Figures 1 to 5 As shown, in this embodiment, a GIS disconnector stroke detection device includes a contact shaft 1, and the outer wall of the contact shaft 1 is provided with a first fixed plate 3 and a second fixed plate 4, the first fixed plate 3 and the second fixed plate 4 are connected by a fixing component, and a first connecting plate 5 is embedded in the interior of the second fixed plate 4, and a pointer 6 is fixedly installed at one end of the first connecting plate 5, and an indicating shaft 2 is provided below the pointer 6.

[0023] The travel angle of the contact shaft 1 of the 110KV disconnector is pointer 60°±indicator shaft 2;

[0024] The outer wall of the indicator shaft 2 is provided with scale lines. The scale lines are based on the positions indicated by the contact shaft 1 rotating sixty degrees. The corresponding open and closed positions are marked at a convenient position for observation, and corresponding scales are carved between the open and closed positions.

[0025] The pointer 6 indicates the scale line on the outer wall of the indicator shaft 2. In actual application, the pointer 6 is adjusted to indicate correctly through the opening and closing operations of the disconnector. This device drives the pointer 6 to move when the contact travels, so that the operator can observe the travel position of the GIS disconnector contact very intuitively and effectively, avoiding electrical accidents caused by improper operation of the GIS disconnector.

[0026] like Figures 1 to 5 As shown, the fixing assembly includes a card slot 18 opened inside the first fixing plate 3, a card block 8 is embedded inside the card slot 18, and a second connecting plate 7 is fixedly installed on one end of the card block 8. The second connecting plate 7 is arranged inside the second fixing plate 4.

[0027] The first fixing plate 3 and the second fixing plate 4 are connected by embedding the clamping block 8 into the clamping groove 18, so that the pointer 6 corresponds to the scale indication on the outer wall of the indicating shaft 2, and the pointer 6 is stably installed on the outer wall of the indicating shaft 2. During operation, the pointer 6 is driven to move when the contact stroke moves to determine whether the opening stroke is in place.

[0028] like Figures 1 to 5As shown, a connecting rod 19 is fixedly installed at the bottom end of the second connecting plate 7, and a third connecting plate 9 is slidably provided on the outer wall of the connecting rod 19. The third connecting plate 9 is fixedly installed on one side of the first connecting plate 5, and a spring 10 is provided at the bottom end of the third connecting plate 9.

[0029] When the pointer 6 needs to be removed for maintenance, the first connecting plate 5 is pressed downward. The movement of the first connecting plate 5 drives the movement of the third connecting plate 9. The movement of the third connecting plate 9 drives the movement of the connecting rod 19. The movement of the connecting rod 19 drives the movement of the second connecting plate 7. The movement of the second connecting plate 7 drives the movement of the clamping block 8, so that the clamping block 8 moves downward inside the clamping slot 18. Then, the first fixing plate 3 is separated from the second fixing plate 4, and they are removed to perform maintenance on the pointer 6.

[0030] When installing the pointer 6, the first fixing plate 3 and the second fixing plate 4 are sleeved on the outer wall of the indicating shaft 2, and the clamping block 8 is embedded to one side of the clamping groove 18. The outer wall of the clamping block 8 contacts the side wall of the clamping groove 18 and is forced to move downward. It is reset after being embedded in the inside of the clamping groove 18 by the elastic potential energy of the spring 10, thereby connecting the first fixing plate 3 and the second fixing plate 4.

[0031] like Figures 1 to 4 As shown, a slide rod 11 is fixedly installed on the top of the second connecting plate 7 , and the contact shaft 1 is slidably installed inside the second slide groove 17 . The second slide groove 17 is opened on the inner wall of the second fixed plate 4 .

[0032] By sliding the slide rod 11 in the second slide groove 17, the movement of the slide rod 11 drives the movement of the second connecting plate 7, and the movement of the second connecting plate 7 drives the movement of the clamping block 8, thereby adjusting the distance that the clamping block 8 slides out of the second fixed plate 4. This allows the device to be installed on the outer wall of the indicating shaft 2 with different diameters, thereby improving the adaptability of the device.

[0033] like Figure 2 and Figure 4 As shown, the top end of the slide rod 11 is connected to a connecting shaft 12 , and the bottom end of the connecting shaft 12 is provided with a gasket 13 .

[0034] like Figure 1 and Figure 3 As shown, a maintenance plate 14 is slidably mounted on the outer wall of the indicator shaft 2 .

[0035] The inner wall of the maintenance plate 14 is provided with cleaning cotton. By rotating the maintenance plate 14 to cover the scale line on the outer wall of the indicator shaft 2, the cleaning cotton can be used to maintain and clean it, thereby improving the clarity of the indication.

[0036] like Figure 3 As shown, a first sliding groove 15 is provided inside the maintenance plate 14 , and a slider 16 is slidably connected to the inner wall of the first sliding groove 15 , and the slider 16 is fixedly mounted on the side wall of the indicating shaft 2 .

[0037] The first chute 15 is set to be L-shaped. When the slider 16 slides to the bottom of the first chute 15, the maintenance plate 14 can be moved upward. By moving the maintenance plate 14 up and down, the cleaning effect of the cleaning cotton on the scale line is improved.

[0038] The utility model provides a GIS isolating switch stroke detection device, the specific working principle is as follows:

[0039] During use, the first fixing plate 3 and the second fixing plate 4 are firstly sleeved on the outer wall of the indicating shaft 2, and the clamping block 8 is inserted into one side of the clamping groove 18. The outer wall of the clamping block 8 contacts the side wall of the clamping groove 18 and is forced to move downward. The elastic potential energy of the spring 10 resets the clamping block 8 after it is inserted into the inner part of the clamping groove 18, thereby connecting the first fixing plate 3 and the second fixing plate 4.

[0040] In actual application, the pointer 6 is driven to move when the indicating shaft 2 moves, so that the operator can observe the travel position of the GIS disconnector contact very intuitively and effectively.

[0041] Although the embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations may be made to these embodiments without departing from the principles and spirit of the present invention, and the scope of the present invention is defined by the appended claims and their equivalents.
