Description

Technical Field

[0001] This utility model relates to the field of power equipment testing technology, specifically to a voltage testing device for substations. Background Technology

[0002] In the daily operation and maintenance of power systems, especially substations, voltage testing is a crucial step in ensuring the safety of power operations. Using voltage testing devices to detect whether high-voltage overhead lines, cable lines, and high-voltage electrical equipment are energized can effectively prevent electric shock accidents, thus building a strong defense for the safety of power workers and the stable operation of power equipment.

[0003] However, traditional voltage detectors are mostly of fixed length, making them unsuitable for voltage testing scenarios at varying heights and distances. For example, when testing high-voltage overhead lines, a fixed-length detector may not be able to reach the required height, forcing workers to use auxiliary tools, increasing the complexity of the operation and reducing efficiency. Similarly, insufficient length limits their applicability when testing distant equipment, resulting in poor usability. Secondly, in terms of handling stability, traditional voltage detectors, when extended, can only be handled with one hand or using unstable methods, making them prone to shaking during operation. This can affect the accuracy of the test results, potentially leading to misjudgments and posing safety hazards to electrical work.

[0004] Therefore, a voltage detection device for substations is proposed. Utility Model Content

[0005] The purpose of this utility model is to provide a voltage detection device for substations in order to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model specifically adopts the following technical solution:

[0007] A voltage detection device for substations includes a voltage detector body, a sleeve, a telescopic rod, and a limiting handle. The telescopic rod is fixedly connected to the voltage detector body. The sleeve is provided with a connecting assembly for telescopic movement of the telescopic rod. An insert block is fixedly connected to the surface of the telescopic rod. A fixing hole is formed on the surface of the telescopic rod. A fixing assembly is provided on the surface of the sleeve. A limiting ring is fixedly sleeved on the surface of the sleeve. A mating assembly is provided between the surface of the sleeve and the surface of the limiting handle. A gripping handle is fixedly connected to the surface of the limiting handle. An insulating rubber sleeve is movably sleeved on the surface of the sleeve.

[0008] Furthermore, the connecting assembly includes a telescopic groove, the surface of the sleeve is provided with the telescopic groove, and the telescopic rod is movably inserted into the inner wall of the telescopic groove. The inner wall of the telescopic groove is provided with a slot, and the insert block is movably inserted into the inner wall of the slot.

[0009] Furthermore, the fixing component includes a connector, the surface of the sleeve is fixedly connected to the connector, a fixing rod is movably inserted into the connector and the fixing rod is movably inserted into the sleeve, a connecting ring is fixedly sleeved on the surface of the fixing rod, a spring is fixedly connected to the surface of the connecting ring, and the end of the spring away from the connecting ring is fixedly connected to the connector.

[0026] like Figure 1 , Figure 2 , Figure 3 , Figure 4As shown, a voltage testing device for substations includes a high-voltage detector body 1, a sleeve 2, a telescopic rod 4, and a limiting handle 9. The telescopic rod 4 is fixedly connected to the high-voltage detector body 1. A connecting component 3 for telescopic movement of the telescopic rod 4 is provided on the sleeve 2. A plug 5 is fixedly connected to the surface of the telescopic rod 4. A fixing hole 6 is opened on the surface of the telescopic rod 4. A fixing component 7 is provided on the surface of the sleeve 2. A limiting ring 8 is fixedly sleeved on the surface of the sleeve 2. A docking component 10 is provided between the surface of the sleeve 2 and the surface of the limiting handle 9. A gripping handle 11 is fixedly connected to the surface of the limiting handle 9. An insulating rubber sleeve 13 is movably sleeved on the surface of the sleeve 2. Specifically, the high-voltage detector body 1 of this voltage testing device for substations is used to detect whether high-voltage overhead lines, cable lines, and high-voltage electrical equipment are energized. It is made of electronic integrated circuits, has audible and visual indication functions, stable and reliable performance, and features full circuit self-testing function and strong anti-interference capabilities. The connecting component 3 on the sleeve 2 is provided... The telescopic rod 4 is inserted and connected to the sleeve 2, allowing the telescopic rod 4 to move telescopically on the sleeve 2. The insert block 5 is inserted and connected to the connecting component 3, preventing the telescopic rod 4 from rotating arbitrarily on the sleeve 2. The fixing hole 6 on the telescopic rod 4 is used in conjunction with the fixing component 7. After the telescopic rod 4 is adjusted, its position on the sleeve 2 is fixed. The limiting handle 9 is connected to the sleeve 2 through the docking component 10. The insulating sleeve 13 can be fixedly connected to the sleeve 2 through the limiting ring 8 and the limiting handle 9. When the telescopic rod 4 is not extended, the device can be picked up and used by grabbing the insulating sleeve 13. At the same time, the insulating sleeve 13 is a vulnerable structure. The insulating sleeve 13 is fixedly installed through the limiting handle 9 and the limiting ring 8, making it easy to replace. The gripping handle 11 is designed so that when the telescopic rod 4 is extended, both hands can be gripped simultaneously to more stably pick up the extended voltage testing device.

[0027] like Figure 3 As shown, the connecting component 3 includes a telescopic groove 301. The telescopic groove 301 is formed on the surface of the sleeve 2, and the telescopic rod 4 is movably inserted into the inner wall of the telescopic groove 301. A slot 302 is formed on the inner wall of the telescopic groove 301, and the insert block 5 is movably inserted into the inner wall of the slot 302. Specifically, the connecting component 3 provides basic structural support for the telescopic movement of the telescopic rod 4 on the sleeve 2. The telescopic groove 301 provides space for the telescopic rod 4 to extend and retract, allowing the telescopic rod 4 to be flexibly adjusted within the sleeve 2 according to different voltage testing height and distance requirements, thus adapting to various voltage testing scenarios. The cooperation between the slot 302 and the insert block 5 restricts the rotation of the telescopic rod 4 within the sleeve 2, ensuring that the telescopic rod 4 can only extend and retract along the direction of the telescopic groove 301, avoiding unnecessary rotation of the telescopic rod 4 during extension and retraction, and ensuring the stability of the extension and retraction adjustment.

[0028] like Figure 2 , Figure 3 As shown, the fixing component 7 includes a connector 701. The connector 701 is fixedly connected to the surface of the sleeve 2. A fixing rod 702 is movably inserted into the connector 701, and the fixing rod 702 is movably inserted into the sleeve 2. A connecting ring 703 is fixedly sleeved on the surface of the fixing rod 702. A spring 704 is fixedly connected to the surface of the connecting ring 703, and the end of the spring 704 away from the connecting ring 703 is fixedly connected to the connector 701. Specifically, the fixing component 7 is designed to achieve a stable positioning of the telescopic rod 4 on the sleeve 2, ensuring that the length remains stable after telescopic adjustment. The connector 701 serves as a basic installation structure, providing movable support for the fixing rod 702. The fixing rod 702 can pass through the sleeve 2 and be inserted into the fixing hole 6 of the telescopic rod 4, directly achieving mechanical locking between the telescopic rod 4 and the sleeve 2. The cooperation between the connecting ring 703 and the spring 704 forms an elastic reset structure. When the fixed rod 702 is pulled outward, the connecting ring 703 compresses the spring 704, causing the rod to disengage from the fixed hole 6, making it easier for the telescopic rod 4 to adjust its length. After the rod is released, the spring force of the spring 704 pushes the connecting ring 703 and the fixed rod 702 to automatically reset and re-insert into the fixed hole 6 to complete the locking.

[0029] like Figure 2 , Figure 4 As shown, the docking assembly 10 includes a threaded connecting rod 1001, which is fixedly connected to the bottom end of the sleeve 2. A threaded hole 1002 is provided on the surface of the limiting handle 9. Specifically, the docking assembly 10 enables a detachable connection between the sleeve 2 and the limiting handle 9, and provides a limiting base for the installation of the insulating sleeve 13. The threaded engagement between the threaded connecting rod 1001 and the threaded hole 1002 securely connects the limiting handle 9 to the bottom end of the sleeve 2, forming a reliable connection structure. This threaded connection method not only facilitates installation and disassembly but also ensures a tight connection, preventing the limiting handle 9 from loosening during use. Simultaneously, after the limiting handle 9 is fixed by the threaded connection, the limiting handle 9 and the limiting ring 8 on the surface of the sleeve 2 cooperate with each other, providing axial limiting for the insulating sleeve 13 fitted on the sleeve 2, preventing the insulating sleeve 13 from sliding axially along the sleeve 2 during use. When the insulating sleeve 13 is worn or aged and needs to be replaced, simply unscrew the limit handle 9 to easily remove the old insulating sleeve 13 and replace it with a new one, simplifying the replacement operation of the insulating sleeve 13.

[0030] like Figure 4As shown, the surface of the grip handle 11 is provided with a gripping sponge sleeve 12; specifically, the gripping sponge sleeve 12 is designed to cushion hand pressure with flexible sponge material, reduce fatigue from prolonged gripping, and improve operating comfort; it conforms to the contour of the hand and increases the contact area, enhancing the stability when both hands grip the grip handle 11 and reducing device shaking; and it utilizes its own coefficient of friction and sweat-absorbing properties to prevent hand slippage due to sweat, ensuring operational safety.

[0031] like Figure 2 , Figure 3 As shown, there are multiple fixing holes 6, and the opening size of the fixing holes 6 is adapted to the fixing rod 702. Specifically, the multiple fixing holes 6 allow the telescopic rod 4 to achieve multiple length adjustments to adapt to different voltage testing scenarios. The matching of its opening size with the fixing rod 702 ensures that the two fit tightly together, preventing the telescopic rod 4 from sliding accidentally and ensuring the stability of the device.

[0032] In summary: When using the voltage testing device in this substation, if it is necessary to adjust the length of the voltage testing device to adapt to different voltage testing needs, pull the fixed insertion rod 702 outward. The connecting ring 703 moves and compresses the spring 704, causing the fixed insertion rod 702 to disengage from the fixed hole 6. Then, push or pull the telescopic rod 4 to move within the telescopic groove 301 of the sleeve 2. The insertion block 5 moves synchronously within the slot 302. After adjusting to the appropriate length, release the fixed insertion rod 702. The spring 704 rebounds, causing the connecting ring 703 and the fixed insertion rod 702 to reset. The fixed insertion rod 702 then inserts into the corresponding fixed hole 6, completing the fixation of the telescopic rod 4. During the voltage testing process, when the telescopic rod 4 extends too far, the operator can hold the gripping handle 11 with both hands, utilizing the increased friction from the gripping sponge sleeve 12 to more stably hold and operate the voltage testing device. When the insulating sleeve 13 is damaged, unscrew the limit handle 9, remove the old insulating sleeve 13, put on the new insulating sleeve 13, and then install the limit handle 9 back to its original position through the engagement of the threaded connecting rod 1001 and the threaded hole 1002. The limit ring 8 and the limit handle 9 are used to limit and fix the insulating sleeve 13.

Those skilled in the art should understand that this utility model is not limited to the above embodiments.
