Description

Technical Field

[0001] This utility model relates to the field of power equipment technology, specifically to an isolating grounding switch for 220kV combined electrical appliances. Background Technology

[0002] In 220kV power systems, the safe and stable operation of combined electrical appliances is crucial for ensuring the reliability of power supply. As one of the key components of 220kV combined electrical appliances, the isolating grounding switch undertakes important tasks such as isolating power supply and grounding for maintenance. However, in the process of using traditional isolating grounding switches, due to the lack of effective moisture-proof and dehumidification measures inside the motor mechanism box, moisture can easily enter and accumulate inside the mechanism box in some high humidity environments, causing electrical components to become damp. This not only affects the insulation performance of the motor, but may also cause faults such as short circuits, shortening the service life of the motor and other control components. Utility Model Content

[0003] The purpose of this utility model is to provide an isolating grounding switch for 220kV combined electrical appliances, which has the advantage of being able to dry the inside of the mechanism box during long-term use of the isolating grounding switch, thus ensuring the stable operation of the control components.

[0004] To achieve the above objectives, this utility model provides the following technical solution: an isolating grounding switch for a 220kV combined electrical appliance, comprising a mechanism box fixedly installed on the top of the isolating grounding switch body, a box cover placed on the top of the mechanism box, a fixed frame fixedly connected to the right side of the mechanism box, fixed plates fixedly connected to both sides of the outer surface of the fixed frame, insertion holes opened at both ends of the fixed plates, a placement box slidably connected to the inner cavity of the fixed frame, a vent hole opened on the left side of the placement box, a silica gel desiccant pack placed in the inner cavity of the placement box, a fixed cover fixedly connected to the right side of the placement box, the left side of the fixed cover contacting the right side of the fixed frame, four elastic clamping plates fixedly connected to both ends of the left side of the fixed cover, the surfaces of the elastic clamping plates movably intersecting the surfaces of the insertion holes, a clamping block fixedly connected to the left end of the elastic clamping plate, and the right side of the clamping block contacting the left side of the fixed plate.

Detailed Implementation

[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0019] Secondly, the term "an embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The phrase "in one embodiment" appearing in different places in this specification does not necessarily refer to the same embodiment, nor is it a single or selective embodiment that excludes other embodiments.

[0020] The components of this application, including the isolating grounding switch body 1, mechanism box 2, operation indicator 3, box cover 4, buckle 5, fixing frame 6, fixing cover 7, hook 8, first rubber pad 9, placement box 10, silica gel desiccant pack 11, second rubber pad 12, air vent 13, fixing plate 14, insertion hole 15, pressing rod 16, elastic locking plate 17, and locking block 18, are all general standard parts or parts known to those skilled in the art. Their structure and principle can be known to those skilled in the art through technical manuals or conventional experimental methods.

[0021] Example 1:

[0022] Please see Figures 1-5 As shown, this utility model provides an isolating grounding switch for a 220kV combined electrical appliance, including a mechanism box 2 fixedly installed on the top of the isolating grounding switch body 1. A box cover 4 is placed on the top of the mechanism box 2. A fixing frame 6 is fixedly connected to the right side of the mechanism box 2. Fixing plates 14 are fixedly connected to both sides of the outer surface of the fixing frame 6. Insertion holes 15 are opened at both ends of the fixing plates 14. A placement box 10 is slidably connected to the inner cavity of the fixing frame 6. A vent hole 13 is opened on the left side of the placement box 10. A silica gel desiccant pack 11 is placed in the inner cavity of the placement box 10. A fixing cover 7 is fixedly connected to the right side of the placement box 10. The left side of the fixing cover 7 contacts the right side of the fixing frame 6. Elastic clamping plates 17 are fixedly connected to both ends of the left side of the fixing cover 7. There are four elastic clamping plates 17. The surface of the elastic clamping plates 17 moves through the surface of the insertion holes 15. A clamping block 18 is fixedly connected to the left end of the elastic clamping plate 17. The right side of the clamping block 18 contacts the left side of the fixing plate 14.

[0023] In this technical solution, the fixed frame 6, the placement box 10, and the fixed cover 7 are used to hold the silica gel desiccant pack 11. During the long-term operation of the isolating grounding switch body 1, the silica gel desiccant pack 11 can absorb moisture in the internal environment of the mechanism box 2, thereby improving the dryness of the mechanism box 2 and ensuring the long-term stable operation of the electrical components inside the mechanism box 2. When personnel need to replace the silica gel desiccant pack 11 periodically, the personnel press the elastic plate 17 to cause the locking block 18 to detach from the surface of the fixed plate 14. Then, the personnel can pull the fixed cover 7 to the right to cause the elastic plate 17 to detach from the inside of the socket 15. The fixed cover 7 moves and causes the placement box 10 to move until the placement box 10 can be removed from the inside of the fixed frame 6. This makes it convenient for personnel to replace the silica gel desiccant pack 11 placed inside the placement box 10 periodically, greatly facilitating the maintenance work.

[0024] It should be noted that the isolating grounding switch body 1 is an existing technology, and it uses the SSDES01 model available on the market, which is widely used in 220kV combined electrical appliances.

[0025] Example 2:

[0026] Based on Embodiment 1, this utility model is as follows: Figures 1-5 As shown, a first rubber pad 9 is affixed to the bottom of the cover 4, and the bottom of the first rubber pad 9 contacts the top of the mechanism box 2. Hooks 8 are fixedly connected to all four sides of the cover 4. Buckles 5 are fixedly connected to all four sides of the upper part of the outer surface of the mechanism box 2. A second rubber pad 12 is affixed to the right side of the fixing frame 6, and the right side of the second rubber pad 12 contacts the left side of the fixing cover 7. A pressing rod 16 is fixedly connected between the middle ends of the two elastic plates 17, and a pressing protrusion is fixedly connected to the middle end of the pressing rod 16. An operation indicator 3 is fixedly installed on the front surface of the mechanism box 2.

[0027] In this technical solution, the first rubber pad 9 effectively improves the sealing performance between the cover 4 and the mechanism box 2. The hook 8 and buckle 5 facilitate personnel to lock the mechanism box 2 and the cover 4, and also facilitate personnel to open the cover 4 in subsequent operations. The second rubber pad 12 effectively improves the sealing performance between the fixed cover 7 and the fixed frame 6. The pressing rod 16 and pressing protrusion facilitate personnel to press and push the elastic plate 17.

[0028] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit the scope of protection of this utility model. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of this utility model without departing from the essence and scope of the technical solutions of this utility model.
