Description

Technical Field

[0001] The utility model relates to the technical field of gas-insulated switchgear, in particular to a fully sealed and fully insulated gas-insulated switchgear with expandable functions. Background Technique

[0002] The full name of the gas-insulated switchgear is a fully insulated and fully enclosed sulfur hexafluoride ring main unit. The outside is welded with fully insulated and fully enclosed stainless steel materials, and the inside is filled with SF6 gas. The gas-insulated switchgear is a general term that includes all unit cabinets. Commonly used ones include the C unit, that is, the load switch module, which is equivalent to the incoming line of the ring main unit; the F unit, that is, the load switch fuse combination module, which is equivalent to the outgoing line of the ring main unit; the V unit, that is, the vacuum switch module, which is equivalent to the circuit breaker unit; the D unit, that is, the cable connection module without an earthing switch, which is equivalent to the lifting cabinet unit; and other less commonly used ones, such as the M cabinet, that is, the metering module, etc. The connection between different functional units can be completed by means of a bus coupler that meets the 10kv power frequency withstand voltage requirement.

[0003] When expanding the cabinet by means of a bus coupler, the bus coupler is connected to the top expansion sleeve on the top of the fully sealed and fully insulated gas-insulated switchgear with expandable functions. The top expansion sleeve is usually exposed outside for a long time when not connected to the bus coupler. Since dust has a certain conductivity, it is necessary to clean the bus coupler and the top expansion sleeve before connecting the bus coupler to the top expansion sleeve, and usually it is also necessary to apply lubricating oil to the bus coupler and the top expansion sleeve to facilitate the connection. Therefore, cleaning paper and lubricating oil need to be configured when configuring tools, and cleaning and applying lubricating oil usually need to be carried out step by step in sequence, which reduces the connection efficiency between the top expansion sleeve of the gas-insulated switchgear and the bus coupler. Therefore, a fully sealed and fully insulated gas-insulated switchgear with expandable functions is proposed for the above problems. Content of the Utility Model

[0004] The purpose of the utility model is to provide a fully sealed and fully insulated gas-insulated switchgear with expandable functions to solve the problems raised in the above background technique.

[0005] To achieve the above purpose, the utility model provides the following technical solutions:

[0006] A fully sealed and fully insulated gas-filled cabinet with expandable functions, comprising a gas-filled cabinet body, a mounting plate, and a top expansion sleeve arranged on the top of the mounting plate. A cleaning sponge sleeve with a wider bottom and a narrower top is sleeved outside the top expansion sleeve. One side of the cleaning sponge sleeve away from the top expansion sleeve is fixedly connected to a conical sleeve box similar in shape to the cleaning sponge sleeve. An anti-sticking inner liner is arranged inside the conical sleeve box. A plurality of through pipes are fixedly connected to the inside of the anti-sticking inner liner. The top of the conical sleeve box and the anti-sticking inner liner is fixedly connected to a connecting pipe arranged in a rectangle. The top of the connecting pipe is fixedly connected to an oil storage box. A positioning plate is fixedly connected to the inner wall of the connecting pipe. A plurality of through holes with equal aperture sizes are opened inside the positioning plate. A baffle plate that fits the inner wall of the connecting pipe is arranged on the top of the positioning plate. One side of the baffle plate is arc-shaped. A connecting rod that penetrates one side of the connecting pipe is fixedly connected to the arc-shaped side of the baffle plate. A handle is fixedly connected to the end of the connecting rod away from the baffle plate.

[0007] Preferably, one end of the through pipe is in contact with the cleaning sponge sleeve, and the end of the through pipe away from the cleaning sponge sleeve is communicated with the anti-sticking inner liner of the conical sleeve box.

[0008] Preferably, one end of the connecting pipe is communicated with the oil storage box, and the end of the connecting pipe away from the oil storage box is communicated with the anti-sticking inner liner of the conical sleeve box.

[0009] Preferably, an elastic damping sleeve is fixedly connected to one side of the connecting pipe. The elastic damping sleeve is sleeved outside the connecting rod and is in contact with the connecting rod.

[0010] Preferably, an elastic sealing sleeve is fixedly connected to the outside of the connecting pipe. The elastic sealing sleeve is sleeved outside the connecting rod and is in contact with the connecting rod.

[0011] Compared with the prior art, the beneficial effects of the present utility model are:

[0012] In the present utility model, through the structure composed of the cleaning sponge sleeve, conical sleeve box, through pipe, connecting pipe, oil storage box, baffle plate, connecting rod, and handle, when it is necessary to clean the top expansion sleeve, the conical sleeve box drives the cleaning sponge sleeve to rotate relative to the top expansion sleeve, so that the cleaning sponge sleeve can act on the top expansion sleeve to clean it. After the cleaning is completed, the connecting rod is dragged away from the connecting pipe through the handle, so that the lubricating oil can flow from the oil storage box through the connecting pipe to the through holes, then penetrate the through holes and flow into the anti-sticking inner liner of the conical sleeve box, and then can flow from the through pipe to the cleaning sponge sleeve, so that the cleaning sponge sleeve is attached with lubricating oil, and then the conical sleeve box is rotated, so that the conical sleeve box drives the cleaning sponge sleeve to evenly apply the lubricating oil on the top expansion sleeve, thus quickly completing the cleaning and lubricating oil application of the top expansion sleeve.

Specific embodiments

[0020] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without making creative efforts shall fall within the protection scope of the present utility model.

[0021] It should be noted that the terms used herein are only for describing specific embodiments and are not intended to limit the exemplary embodiments according to the present application. As used herein, unless otherwise clearly specified in the context, the singular form is also intended to include the plural form. In addition, it should be understood that when the terms "comprise" and / or "include" are used in this specification, they indicate the presence of features, steps, operations, devices, components, and / or combinations thereof.

[0022] Unless otherwise specifically stated, the relative arrangements, numerical expressions, and numerical values of the components and steps set forth in these embodiments do not limit the scope of the present utility model. At the same time, it should be understood that, for the sake of convenience in description, the dimensions of the various parts shown in the drawings are not drawn in actual proportional relationships. Technologies, methods, and devices known to those of ordinary skill in the relevant art may not be discussed in detail, but where appropriate, such technologies, methods, and devices should be regarded as part of the authorization specification. In all the examples shown and discussed here, any specific value should be construed as merely exemplary and not as a limitation. Therefore, other examples of the exemplary embodiments may have different values. It should be noted that like reference numerals and letters denote like items in the following drawings, and thus, once an item is defined in one drawing, it does not need to be further discussed in subsequent drawings.

[0023] In the description of the present utility model, it should be understood that the orientation or positional relationships indicated by orientation words such as "front, rear, upper, lower, left, right", "lateral, vertical, perpendicular, horizontal", and "top, bottom", etc. are generally based on the orientation or positional relationships shown in the drawings. It is only for the convenience of describing the present utility model and simplifying the description. Without contrary statements, these orientation words do not indicate and imply that the device or element referred to must have a specific orientation or be constructed and operated in a specific orientation. Therefore, it cannot be understood as a limitation on the protection scope of the present utility model; the orientation words "inside, outside" refer to the inside and outside relative to the contour of each component itself.

[0024] For the convenience of description, spatial relative terms such as "above...", "over...", "on the upper surface of...", "upper...", etc. can be used here to describe the spatial positional relationships of one device or feature to other devices or features as shown in the drawings. It should be understood that the spatial relative terms are intended to include different orientations in use or operation in addition to the orientation described in the drawings for the device. For example, if the device in the drawing is inverted, the device described as "above other devices or structures" or "over other devices or structures" will then be positioned "below other devices or structures" or "under other devices or structures". Thus, the exemplary term "above..." can include both the orientations of "above..." and "below...". The device can also be positioned in other different ways (rotated 90 degrees or in other orientations), and corresponding interpretations should be made for the spatial relative descriptions used here.

[0025] In addition, it should be noted that the use of words such as "first", "second", etc. to limit components is only for the convenience of distinguishing the corresponding components. Without otherwise stating, the above words have no special meanings. Therefore, it cannot be understood as a limitation on the protection scope of the present utility model.

[0026] Please refer toFigures 1-6 , the present utility model provides a technical solution:

[0027] A fully sealed and fully insulated gas-filled cabinet with expandable functions, including a gas-filled cabinet body 1, a mounting plate 2, and a top expansion sleeve 3 arranged on the top of the mounting plate 2. A cleaning sponge sleeve 4 with a wider bottom and narrower top is sleeved on the outer side of the top expansion sleeve 3. A conical sleeve box 5 similar in shape to the cleaning sponge sleeve 4 is fixedly connected to the side of the cleaning sponge sleeve 4 away from the top expansion sleeve 3. An anti-sticking inner liner 6 is arranged inside the conical sleeve box 5. A plurality of through pipes 7 are fixedly connected to the inner side of the anti-sticking inner liner 6. A connecting pipe 8 arranged in a rectangle is fixedly connected to the top of the conical sleeve box 5 and the anti-sticking inner liner 6. A storage oil box 9 is fixedly connected to the top of the connecting pipe 8. A positioning plate 10 is fixedly connected to the inner wall of the connecting pipe 8. A plurality of through holes 11 with equal aperture sizes are opened inside the positioning plate 10. A baffle 12 that fits the inner wall of the connecting pipe 8 is arranged on the top of the positioning plate 10. One side of the baffle 12 is arc-shaped. A connecting rod 13 that penetrates one side of the connecting pipe 8 is fixedly connected to the arc-shaped side of the baffle 12. A handle 14 is fixedly connected to the end of the connecting rod 13 away from the baffle 12.

[0028] One end of the through pipe 7 is in contact with the cleaning sponge sleeve 4, and the end of the through pipe 7 away from the cleaning sponge sleeve 4 is communicated with the anti-sticking inner liner 6 of the conical sleeve box 5. This setting enables the lubricating oil to flow from the anti-sticking inner liner 6 to the cleaning sponge sleeve 4 along the through pipe 7; one end of the connecting pipe 8 is communicated with the storage oil box 9, and the end of the connecting pipe 8 away from the storage oil box 9 is communicated with the anti-sticking inner liner 6 of the conical sleeve box 5. This setting enables the lubricating oil to flow from the storage oil box 9 to the anti-sticking inner liner 6; an elastic damping sleeve 15 is fixedly connected to one side of the connecting pipe 8. The elastic damping sleeve 15 is sleeved on the outer side of the connecting rod 13 and is in contact with the connecting rod 13. This setting enables the elastic damping sleeve 15 to generate a certain frictional force on the baffle 12 and the connecting rod 13, thereby reducing the occurrence of accidental sliding of the connecting rod 13 and the baffle 12; an elastic sealing sleeve 16 is fixedly connected to the outer side of the connecting pipe 8. The elastic sealing sleeve 16 is sleeved on the outer side of the connecting rod 13 and is in contact with the connecting rod 13. This setting enables the elastic sealing sleeve 16 to enhance the sealing performance between the connecting rod 13 and the connecting pipe 8.

[0029] Workflow: The conical sleeve box 5 and the cleaning sponge sleeve 4 can block the contact between external dust and the top expansion sleeve 3 to a certain extent. When it is necessary to clean the top expansion sleeve 3, hold and rotate the conical sleeve box 5, so that the conical sleeve box 5 drives the cleaning sponge sleeve 4 to rotate relative to the top expansion sleeve 3, so that the cleaning sponge sleeve 4 can act on the top expansion sleeve 3 to clean it. When the cleaning is completed, drag the connecting rod 13 away from the connecting pipe 8 through the handle 14, so that the connecting rod 13 drives the baffle 12 to move relative to the positioning plate 10. During this process, the arc-shaped side of the baffle 12 will sequentially pass through the elastic damping sleeve 15 and the elastic sealing sleeve 16. The elastic damping sleeve 15 will generate a certain frictional force on the baffle 12 and the connecting rod 13, so as to reduce the occurrence of accidental sliding of the connecting rod 13 and the baffle 12. The elastic sealing sleeve 16 can enhance the sealing performance between the connecting rod 13 and the connecting pipe 8. When the baffle 12 completely disengages from the elastic damping sleeve 15, the shielding of the inner through hole 11 of the positioning plate 10 by the baffle 12 is completely cancelled. The lubricating oil can flow from the oil storage box 9 through the connecting pipe 8 to the through hole 11, then pass through the through hole 11 and flow into the anti-sticking inner liner 6 of the conical sleeve box 5, and then can flow from the through pipe 7 to the cleaning sponge sleeve 4, so that the cleaning sponge sleeve 4 is attached with lubricating oil. Then rotate the conical sleeve box 5 again, so that the conical sleeve box 5 drives the cleaning sponge sleeve 4 to evenly apply the lubricating oil on the top expansion sleeve 3, thus quickly completing the cleaning and lubricating oil application of the top expansion sleeve 3. Then separate the conical sleeve box 5 and the cleaning sponge sleeve 4 from the top expansion sleeve 3, and the completed cleaning bus coupler can be connected. The top expansion sleeve 3 is installed through the mounting plate 2, and the mounting plate 2 is installed on the top of the gas-insulated switchgear body 1 by bolts.

[0030] Although the embodiments of the present invention have been shown and described, those of ordinary skill in the art can understand that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principles and spirit of the present invention. The scope of the present invention is defined by the appended claims and their equivalents.
