Description

Technical Field

[0001] The utility model relates to the field of high-voltage electrical testing devices, and more specifically to a high-voltage live display electrical testing device. Background Art

[0002] High-voltage testers, with their sound and light indicators, are manufactured using electronic integrated circuits and offer stable and reliable performance. They feature full-circuit self-testing and strong anti-interference capabilities. The GD series high-voltage testers are suitable for testing 220V-500V, 6kV, 10kV, 35kV, 110kV, 220kV, and 500kV AC transmission and distribution lines and equipment. Whether day or night, indoors at substations or on outdoor overhead lines, they provide accurate and reliable service. They are essential safety devices for power systems and electrical departments in industrial and mining enterprises. To enhance convenience and safety, the tester's insulated grip is often configured as an insulated telescopic rod.

[0003] Based on the above, the inventors have found that when using existing high-voltage electroscopes, it is rather cumbersome to adjust the length of the insulating telescopic rod. Since the length adjustment needs to be made in real time according to the height of the voltage device in actual use, the telescopic rod of the existing electroscope needs to be manually pulled out to adjust the length, which greatly reduces the convenience of using the electroscope. Therefore, in view of this, the inventors have studied and improved the existing structure and provided a high-voltage live display electroscope device in order to achieve the purpose of greater practical value.

When the shortening is completed, the pawl is closed so that the pawl engages with the ratchet, so that the length of the insulating telescopic rod is fixed.

Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention.

[0024] Example:

Through this device, it is convenient for the staff to effectively adjust the length of the insulating telescopic rod 3, thereby improving the convenience of using the high-voltage tester body 1.

[0026] See Figure 2 、 3, 4. One end of the conical compression spring 5 is fixedly connected to the top end of the inner wall of the insulating telescopic rod 3, and the other end of the conical compression spring 5 is fixedly connected to the bottom end of the inner wall of the insulating telescopic rod 3. Through the conical compression spring 5 inside the insulating telescopic rod 3, when the insulating telescopic rod 3 is contracted, the conical compression spring 5 can be contracted together with the insulating telescopic rod 3. When the insulating telescopic rod 3 needs to be extended, the conical compression spring 5 can be used to expand and extend the insulating telescopic rod 3; the fixing rope 6 is located in the inner ring of the insulating telescopic rod 3, and one end of the fixing rope 6 extends to the inside of the fixing box 4 through the through groove; one end of the fixing rope 6 is fixedly connected to the outer wall of the winding drum 8, and the fixing rope 6 is wound around the outside of the winding drum 8. When the insulating telescopic rod 3 needs to be shortened, the handle 9 is turned to pull one end of the insulating telescopic rod 3 downward, and the fixing rope 6 is wound around the winding drum 8, thereby avoiding manual pulling of the insulating telescopic rod 3 for length adjustment.

[0027] See Figure 3 、 4 The outer wall of the handle 9 is fixedly mounted with an anti-slip pad 10, and the outer side of the anti-slip pad 10 is fixedly mounted with rubber particles. The anti-slip pad 10 on the handle 9 can effectively increase the friction between the handle 9 and the palm of the staff; the outer wall of the fixed shaft 7 is fixedly mounted with a ratchet 11, and the outer wall of the fixed box 4 is mounted with a pawl 12 through a rotating shaft. One end of the pawl 12 is engaged with the ratchet 11 and is connected to each other. When the handle 9 is shaken to shorten the insulating telescopic rod 3, the pawl 12 is engaged with the ratchet 11, which can limit the winding reel 8 on the fixed shaft 7, thereby fixing the position of one end of the insulating telescopic rod 3 driven by the fixed rope 6.

[0028] During use: first, when the staff needs to extend the insulating telescopic rod 3, the pawl 12 is opened upward, and then the elastic force of the conical compression spring 5 inside the insulating telescopic rod 3 is used to unfold and stretch the insulating telescopic rod 3. At the same time, the fixed rope 6 will be paid out on the winding reel 8. When the insulating telescopic rod 3 reaches the specified length, the staff limits the handle 9 and engages the pawl 12 with the ratchet 11 so that the length of the insulating telescopic rod 3 can be fixed. When the insulating telescopic rod 3 needs to be shortened, the staff turns the handle 9 so that the fixed shaft 7 drives the winding reel 8 to reel the fixed rope 6. At the same time, the fixed rope 6 will pull the insulating telescopic rod 3 downward to shorten. When the shortening is completed, the pawl 12 is closed so that the pawl 12 is engaged with the ratchet 11, and the length adjustment of the insulating telescopic rod 3 can be completed.
