Description

Technical Field

[0001] This utility model relates to the field of power equipment technology, specifically to a high-voltage disconnector operating mechanism. Background Technology

[0002] The operating mechanism of a high-voltage disconnector switch is a device used to control the opening and closing of the high-voltage disconnector switch, realizing the opening and closing operation. Through different power transmission methods, it provides power for the opening and closing actions of the disconnector switch, ensuring that the disconnector switch can reliably disconnect or connect the circuit. It ensures operational safety: some operating mechanisms are equipped with mechanical or electrical interlocking functions to prevent misoperation and ensure the safety of operators and equipment. It meets different operational needs: the operating speed, force, and other parameters can be adjusted according to the operating requirements of the power grid to adapt to different working environments and operating scenarios. The operation method is to directly operate the handle or transmission rod manually to achieve the opening and closing actions of the disconnector switch. It is generally suitable for occasions with low operating frequency and no need for remote operation, such as some small substations or outdoor temporary power equipment. It features simple structure, low cost, convenient maintenance, no need for external power supply, relatively intuitive operation, and can be directly controlled by operators on-site.

[0003] Currently, the operating mechanism of high-voltage isolating switches exposed to the outside world has its shaft and connector exposed to the outside, making it susceptible to rainwater corrosion. This causes the shaft to rust, resulting in inflexible opening and closing during operation, increasing the maintenance frequency, reducing the overall service life of the mechanism, and making it unsuitable for actual operation.

[0004] In view of the above, this application is hereby submitted. Utility Model Content

[0005] The purpose of this utility model is to provide a high-voltage disconnect switch operating mechanism to solve the problems mentioned in the background art.

[0006] To solve the above-mentioned technical problems, this utility model provides a high-voltage disconnect switch operating mechanism, including a base, an insulating component, a first connector, a second connector, a knife switch component, a rotating shaft, and a protective sleeve;

[0007] Insulating components are installed at intervals on the top surface of the base. A first connector is installed on the top surface of the left insulating component, and a second connector is installed on the top of the right insulating component. A knife switch is installed between the first and second connectors. The knife switch is connected to the rotating shaft through a shaft seat. A protective sleeve is fitted on the outside of the rotating shaft.

[0008] In one embodiment, the protective sleeve consists of an upper sleeve, a lower sleeve, and a protective cavity. When the opposing surfaces of the upper sleeve and the lower sleeve abut against each other, they together form a complete protective sleeve structure. The middle part of the upper sleeve and the lower sleeve forms a protective cavity, and the protective cavity is in a sleeved state with the rotating shaft.

[0009] In one embodiment, auxiliary sleeves are installed on both sides of the upper and lower sleeves, and the auxiliary sleeves are fitted over the mounting bolts of the rotating shaft.

[0010] In one embodiment, the outer side of the secondary sleeve has a mounting groove, in which ball bearings are mounted in a semi-circular array, and the ball bearings contact the inner sidewall of the guillotine.

[0011] In one embodiment, the outer peripheral surface of the protective cavity is wrapped with insulating tape.

[0012] In one embodiment, a switch is installed inside the right end of the knife gate. The switch consists of a mounting plate, a socket, a positioning groove, and an extension tube. The mounting plate has a socket in the front and rear directions, a positioning groove at the top of the socket, and an extension tube installed at the rear end of the socket.

[0013] In one embodiment, both the socket and the extension tube are hexagonal structures.

[0014] Compared with the prior art, the beneficial effects of this utility model are:

[0015] 1. The protective sleeve protects the shaft, preventing direct contact with rainwater and reducing corrosion damage, thus extending the overall lifespan of the device. The upper and lower sleeves work together to protect the shaft while facilitating easy disassembly and maintenance. Maintenance simply requires separating the two sleeves, eliminating the need for excessive connecting parts and simplifying the mechanism. The secondary sleeve further enhances the protection of the shaft and related components, while the insulating tape improves installation convenience.

[0016] 2. By incorporating ball bearings, the smoothness of contact between the knife switch and the overall protective sleeve is improved, avoiding high friction issues. The knife switch is operated manually by inserting a hand tool into the socket and inserting the extension plate into the positioning groove. Attached Figure Description

[0023] like Figures 1-2 As shown, insulating components 2 are installed at intervals on the top surface of the base 1. A first connector 3 is installed on the top surface of the left insulating component 2, and a second connector 4 is installed on the top of the right insulating component 2. A knife switch 5 is installed between the first connector 3 and the second connector 4. The knife switch 5 is connected to the rotating shaft 6 through a shaft seat. A protective sleeve 7 is fitted on the outside of the rotating shaft 6. The protective sleeve 7 protects the rotating shaft 6, prevents rainwater from directly contacting the rotating shaft 6, reduces the corrosion damage caused by rainwater and the rotating shaft 6, and improves the service life of the overall device.

[0024] Preferably, in one embodiment, such as Figure 2 As shown, the protective sleeve 7 consists of an upper sleeve 71, a lower sleeve 72, and a protective cavity 73. When the opposing surfaces of the upper sleeve 71 and the lower sleeve 72 abut against each other, they together form a complete protective sleeve 7 structure. The protective cavity 73 is formed in the middle of the upper sleeve 71 and the lower sleeve 72. The protective cavity 73 is sleeved with the rotating shaft 6. Through the cooperation of the upper sleeve 71 and the lower sleeve 72, the rotating shaft 6 is protected while the protective sleeve 7 is easily disassembled and maintained. During maintenance, the two can be separated without too many connecting parts, making the mechanism simpler.

[0025] Preferably, in one embodiment, such as Figure 2 As shown, auxiliary sleeves 74 are installed on both sides of the upper sleeve 71 and the lower sleeve 72.

[0026] Preferably, in one embodiment, such as Figure 2 As shown, the outer side of the sub-sleeve 74 has an installation groove, and ball bearings 75 are installed in a semi-circular array in the groove. The ball bearings 75 contact the inner side wall of the knife switch 5. The ball bearings 75 improve the smoothness of contact between the knife switch 5 and the overall protective sleeve 7, and avoid the problem of high friction.

[0027] Preferably, in one embodiment, such as Figure 2 As shown, the outer periphery of the protective cavity 73 is wrapped with insulating tape 76, which improves the ease of installation.

[0028] Preferably, in one embodiment, such as Figures 1-3 As shown, a switch 8 is installed inside the right side end of the knife switch 5. The switch 8 consists of a mounting plate 81, a socket 82, a positioning groove 83, and an extension tube 84. The mounting plate 81 has a socket 82 in the front and rear directions. The top of the socket 82 has a positioning groove 83. The rear end of the socket 82 is equipped with an extension tube 84. During operation, a handheld tool is inserted into the socket 82 and the extension plate is inserted into the positioning groove 83 to complete the operation of the knife switch 5.

[0029] Preferably, in one embodiment, the insertion hole 82 and the extension tube 84 are both hexagonal structures, which are intended to avoid the slippage that occurs with traditional round holes and improve operational stability.

[0030] Working principle:

[0031] The protective sleeve 7 protects the rotating shaft 6, preventing rainwater from directly contacting it, reducing corrosion damage, and extending the overall lifespan of the device. The upper sleeve 71 and lower sleeve 72 work together to protect the rotating shaft 6 while facilitating the disassembly and maintenance of the protective sleeve 7. Maintenance simply requires separating the two sleeves, eliminating the need for excessive connecting parts and simplifying the mechanism. The secondary sleeve 74 further enhances the protection of the rotating shaft 6 and its related components. The insulating tape 76 improves installation convenience. The ball bearing 75 improves the smoothness of contact between the knife switch 5 and the overall protective sleeve 7, preventing high friction. The knife switch 5 is operated by inserting a hand tool into the socket 82 and inserting the extension plate into the positioning groove 83.
