Description

Technical Field

[0001] This utility model relates to the technical field of substation operation and maintenance, and in particular to substation disconnect switches that prevent misoperation. Background Technology

[0002] In the operation and maintenance of substations, the disconnector switch box is a crucial component that protects the internal operating mechanisms from environmental influences and ensures stable equipment operation. Currently, most common disconnector switch box doors use a combination of hinges and ordinary locks for fixation, a structure that meets basic opening and closing requirements in daily use.

[0003] However, in actual operation, due to the lack of clear positioning guidance and secondary locking mechanism when the cabinet door closes, vibration or human negligence may cause the door to not close completely, thus posing a potential operational risk due to the intervention of external foreign objects or accidental contact. In addition, traditional lock structures are prone to wear after frequent opening and closing, affecting the reliability of long-term use, and the operation process is relatively cumbersome, which is not conducive to maintenance personnel to quickly and accurately complete inspection and maintenance work. Utility Model Content

[0004] The purpose of this invention is to provide a substation disconnect switch to prevent misoperation, thereby solving the problems mentioned in the background art.

[0005] The technical solution adopted in this utility model is: The anti-misoperation substation disconnect switch includes a substation disconnect switch body, a disconnect switch mechanism box at the bottom of the substation disconnect switch body, a door hinged to the disconnect switch mechanism box, two positioning slots on the side of the disconnect switch mechanism box, two positioning blocks installed on the side of the door, the two positioning blocks respectively fitting into the corresponding positioning slots, four through holes on the side of the disconnect switch mechanism box, a positioning rod horizontally sliding in each through hole, two positioning holes on each of the two positioning blocks, and the ends of the four positioning rods respectively fitting into the corresponding positioning holes.

[0006] Optionally, a pull block is installed on the outer surface of the door, and an anti-slip pad is provided on the pull block.

[0007] Optionally, a U-shaped block is installed on the outer surface of the disconnector mechanism box. The U-shaped block has four horizontal holes. Each positioning rod slides horizontally in the corresponding horizontal hole, and a positioning ring is sleeved at the end of each positioning rod.

[0008] Optionally, the ends of the four positioning rods are connected to vertical blocks in pairs, and a connecting rod connects the two vertical blocks.

[0009] Optionally, springs are connected to the outer surfaces of both vertical blocks, and the ends of the two springs are connected to the outer surfaces of the U-shaped blocks.

[0010] Optionally, a grounding switch mechanism box is also installed at the bottom of the substation disconnector body.

[0011] Optionally, the substation disconnect switch body has a base frame, a base, and a rod-type insulating support. The base is installed on the top of the base frame, and the rod-type insulating support is installed on the top of the base. The disconnect switch mechanism box and the grounding switch mechanism box are both located at the bottom of the base frame.

[0012] Compared with the prior art, the beneficial effects of this utility model are: This utility model solves the problems of insufficient locking reliability and accidental opening due to vibration or incomplete closure of the existing isolating switch mechanism box door by using a primary guide engagement structure between the positioning block and the positioning groove, and a secondary mechanical pin locking structure between the positioning rod and the positioning hole. It ensures that the box door can be firmly mechanically retained after closing, effectively preventing the possibility of external foreign objects or personnel accidentally touching the operating mechanism.

[0013] This utility model solves the problem of cumbersome operation steps and inability to automatically reset the door locking mechanism by setting up a linkage reset mechanism composed of connecting rods, vertical blocks and springs. It integrates the movement of multiple independent positioning rods into a synchronous action, so that the operator can release all locking points with a single pull. After release, the spring immediately drives the locking component to automatically reset and complete the locking, which greatly simplifies the operation process and shortens the maintenance time.

[0017] In the description of this utility model, it should be understood that the terms "center", "longitudinal", "transverse", "length", "width", "thickness", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", "clockwise", "counterclockwise", "axial", "radial", "circumferential", etc., indicating the orientation or positional relationship are based on the orientation or positional relationship shown in the accompanying drawings, or the orientation or positional relationship commonly used when the product of this utility model is in use, or the orientation or positional relationship commonly understood by those skilled in the art. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0018] Given that the existing technology lacks a clear secondary locking mechanism when the enclosure door is closed, the door may not be fully closed due to vibration or human negligence. Therefore, it is necessary to design a substation disconnect switch to prevent misoperation.

[0019] like Figure 1-4 As shown, this utility model embodiment provides a substation disconnect switch to prevent misoperation, including a substation disconnect switch body 1, a disconnect switch mechanism box 2 at the bottom of the substation disconnect switch body 1, and a grounding switch mechanism box 3 at the bottom of the substation disconnect switch body 1. The disconnect switch mechanism box 2 and the grounding switch mechanism box 3 are respectively used to accommodate the operating mechanisms of the disconnect switch and the grounding switch.

[0020] The disconnector switch mechanism box 2 is hinged with a door 4. The side of the disconnector switch mechanism box 2 has two positioning grooves 201. Two positioning blocks 5 are installed on the side of the door 4. The two positioning blocks 5 are respectively engaged in the corresponding positioning grooves 201. When the door 4 is closed, the two positioning blocks 5 can be accurately inserted into the corresponding positioning grooves 201 to complete the initial alignment and pre-fixation of the door. The side of the disconnector switch mechanism box 2 also has four through holes. Each through hole has a horizontally sliding positioning rod 7. The two positioning blocks 5 each have two positioning holes 501. The ends of the four positioning rods 7 are respectively engaged in the corresponding positioning holes 501. The four positioning rods 7 lock the positioning blocks 5 a second time.

[0021] Furthermore, a pull block 401 is installed on the outer surface of the door 4. The pull block 401 is equipped with an anti-slip pad, which makes it easy to operate. The anti-slip pad on the surface of the pull block 401 ensures that the operator feels comfortable and is not prone to slipping when opening and closing the door 4, thus improving the safety and convenience of operation.

[0022] Furthermore, a U-shaped block 6 is installed on the outer surface of the disconnector mechanism box 2. The U-shaped block 6 has four horizontal holes 601. Each positioning rod 7 is horizontally slidably fitted in the corresponding horizontal hole 601. The end of each positioning rod 7 is fitted with a positioning ring 11. The U-shaped block 6 serves as a guide and mounting base for the positioning rod 7, ensuring the stability of the movement of the positioning rod 7. The positioning ring 11 plays a mechanical limiting role, preventing the positioning rod 7 from accidentally coming out of the horizontal hole 601.

[0023] Furthermore, vertical blocks 8 are connected to the ends of the four positioning rods 7 in pairs, and a connecting rod 10 is connected between the two vertical blocks 8. The vertical blocks 8 and the connecting rod 10 connect the four independent positioning rods 7 into a whole, realizing the synchronous linkage of all positioning rods 7. This allows all locking points to be unlocked or locked at the same time with one action, making the operation simple and efficient.

[0024] Furthermore, springs 9 are connected to the outer surfaces of the two vertical blocks 8, and the ends of the two springs 9 are connected to the outer surfaces of the U-shaped blocks 6. The automatic reset mechanism of the springs 9 enables the door 4 to be automatically locked after closing, without the need for additional manual operation of the latch, which greatly improves the convenience of use and the reliability of locking.

[0025] Furthermore, the substation disconnector body 1 has a base frame 101, a base 102, and a rod-type insulating support 103. The base 102 is provided on the top of the base frame 101, and the rod-type insulating support 103 is provided on the top of the base 102. The disconnector mechanism box 2 and the grounding switch mechanism box 3 are both located at the bottom of the base frame 101. The base frame 101, the base 102, and the rod-type insulating support 103 are all part of the main structure of the substation disconnector body 1, and will not be described in detail here.

[0026] Working principle: When opening the door 4, the operator pulls the connecting rod 10 outward (i.e., away from the door 4). The movement of the connecting rod 10 causes the two vertical blocks 8 connected to it to move outward together. The movement of the vertical blocks 8 then causes all four positioning rods 7 to slide horizontally in their respective horizontal holes 601, so that their ends exit from the positioning holes 501 on the positioning block 5, thereby releasing the restriction on the positioning block 5. During this process, the two springs 9 connected between the vertical block 8 and the U-shaped block 6 are stretched and store elastic potential energy. At this time, the lock of the door 4 has been released, and the operator can pull the door 4 open through the pull block 401. The positioning block 5 then comes out of the positioning groove 201.

[0027] When closing the door 4, the operator closes the door 4 by pulling the block 401, so that the two positioning blocks 5 are accurately inserted into the positioning grooves 201 on the side of the isolating switch mechanism box 2. Then, the operator releases the pulling rod 10. At this time, the two stretched springs 9 release their stored elastic potential energy and quickly rebound, pushing the two vertical blocks 8 to reset towards the door 4. The reset movement of the vertical blocks 8 drives the four positioning rods 7 to move horizontally inward, so that their ends are accurately inserted into the positioning holes 501 of the corresponding positioning blocks 5, thus completing the automatic locking of the door 4. The contact between the positioning ring 11 and the inner surface of the U-shaped block 6 limits the extreme insertion position of the positioning rods 7, ensuring reliable locking and preventing over-insertion.

[0028] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
