Description

Technical Field

[0001] The invention belongs to the field of insulator zero detection, and particularly relates to a rapid zero detection device for an insulator string and a use method thereof. Background Art

[0002] To ensure the safe operation of transmission lines and the safety of personnel working on live lines, porcelain insulators must be inspected. First, during line outages and maintenance, maintenance personnel must test each insulator individually with a handheld resistance tester. This is not only labor-intensive, but also increases the risk of climbing up the insulator string to perform zero measurements on each insulator. Second, before entering the electric field during live work, maintenance personnel use a handheld insulator operating rod to perform zero measurements using the spark gap method or voltage distribution method. The zero measurement device is mounted on the top of the insulator operating rod. The operator uses themselves as a fulcrum, holding the end of the insulator operating rod and lifting and lowering each insulator to perform zero measurements. This is time-consuming, labor-intensive, and labor-intensive. When measuring insulators on the conductor side, the insulator operating rod cannot be lifted for zero measurement due to its distance, or the maintenance personnel's body and arms lean forward, which can easily short-circuit some insulators, resulting in insufficient safety distance and causing danger.

[0003] Although there are some technologies that use drones to detect zero-value insulators, there are still many scenarios where drones cannot fly for inspection: for example, ultra-high voltage substations have complex internal structures and are no-fly zones for drones, and manual inspection of the portal frame insulator strings in the station is still required; a large number of transmission lines cross jungles and mountainous areas, where signals are sparse and obstacles are numerous, making drones unable to fly autonomously; some lines are in no-fly zones for drone aviation control, and drones cannot take off.

DETAILED DESCRIPTION

[0031] To make the objectives, technical solutions, and advantages of the present invention more clear, the technical solutions of the present invention will be clearly and completely described below in conjunction with the accompanying drawings in the embodiments of the present invention. The embodiments described in this application are only part of the embodiments of the present invention, not all of them. Based on the spirit of the present invention, other embodiments obtained by ordinary technicians in this field without making creative efforts are all within the scope of protection of the present invention.

[0032] like Figure 1As shown, the present invention provides an insulator string rapid zero detection device, comprising:

[0033] Main frame 1, driving structure 2, strip slider 3, detection structure 4 and operating rod 5;

[0034] The driving structure 2 and the strip slider 3 are arranged on the main frame 1, and the detection structure 4 is connected to the driving structure 2, and the detection structure 4 is also connected to the operating rod 5;

[0035] The driving structure 2 is the power execution structure of the zero measuring device; the strip slider 3 slides on the insulator string to support the weight of the zero measuring device; the detection structure 4 is used to detect the single-piece insulator through force transmission.

[0036] Preferably, there are two groups of strip sliders 3, which are symmetrically arranged on both sides of the bottom of the main frame 1, and the strip sliders 3 are used to slide on the insulator string.

[0037] like Figure 2-4 As shown, the driving structure 2 includes a triangular card string wheel 2-1, a connecting rod steering gear 2-2 and a Z-type steering gear 2-3.

[0038] Preferably, one connection end of the triangular card string wheel 2-1 is connected to the connecting rod steering device 2-2, and the other connection end is suspended in the air.

[0039] Preferably, the material of the triangular card string wheel 2-1 is polyethylene, which has high lubricity.

[0040] Preferably, the strip slider 3 on the same side as the triangular card string wheel 2-1 is located on the outside of the triangular card string wheel 2-1.

[0041] Preferably, one end of the connecting rod steering gear 2-2 is connected to the connecting end of the triangular card string wheel 2-1, and the other end is connected to the Z-type steering gear.

[0042] like Figure 5 As shown, the detection structure 4 includes two zero measuring instrument probes 4-1, a resistance rod 4-2 and an auxiliary connecting rod 4-3, wherein one zero measuring instrument probe 4-1 is located at the top of the resistance rod 4-2, and the other zero measuring instrument probe 4-1 is separated from the zero measuring instrument probe 4-1 set at the top by a set distance, and the two zero measuring instrument probes are oriented in the same direction.

[0043] Preferably, the set distance can be adaptively adjusted by the staff according to different models of insulator strings in actual use.

[0044] Preferably, one end of the auxiliary connecting rod 4-3 is connected to the resistance rod 4-2, and the other end is connected to the Z-type diverter 2-3.

[0045] Embodiment 2 of the present invention provides a method for using an insulator string rapid zero detection operation device, comprising:

[0046] When measuring zero, the staff holds the operating lever 5 and drags the zero measuring device, and the triangular clamping string wheel 2-1 of the driving structure 2 is clamped on one side of the insulator string and moves. Using its own gravity, it falls between the insulators and drives the connecting rod diverter 2-2 to rotate. The rotation of the connecting rod diverter 2-2 drives the Z-type diverter 2-3 to rotate, and drives the zero measuring instrument probe 4-1 to fall onto the insulator steel cap.

[0047] like Figure 6 、 7 As shown, when in use, by pushing the operating lever forward, the triangular card string wheel 2-1 slides over the insulator to reach between insulators A-2 and A-3, and the triangular card string wheel 2-1 falls, driving the connecting rod diverter 2-2 and the Z-type diverter 2-3 to be transferred to 4-1 zero measuring instrument probe to fall on the A-1 and A-2 steel caps to form zero measurement;

[0048] When the triangular card string wheel 2-1 slides to the top of the insulator A-2, the triangular card string wheel 2-1 falls, driving the connecting rod diverter 2-2 and the Z-type diverter 2-3 to be transferred to the zero measuring instrument probe 4-1, which falls to the top of the insulator A-1 without forming a zero measurement. The back and forth sliding work forms a zero measurement between the high-voltage end and the low-voltage end.

[0049] The advantage of using drones for insulator zero testing is that it's difficult for workers to reach the base of the tower, such as in deep mountain forests or isolated islands. Drones' high maneuverability allows them to fly close to the insulators for inspection, reducing the risk of workers having to climb mountains or wade through water, while also improving timeliness. However, the disadvantage is that when operating drones for long-distance inspections, the risk of drone crashes can be compromised by poor visibility, electromagnetic interference with wireless communication equipment, and other environmental factors.

[0050] Manually using an insulator zero measuring device for zero measurement has the following advantages in a relatively low environment:

[0051] 1. This detection device is more convenient and faster than the previous manual detection.

[0052] 2. To ensure the safety of personnel, inspection personnel only need to work on the cross arm of the tower and no longer need to go to the high-voltage end for inspection.

[0053] 3. Improved detection efficiency and accuracy.

[0054] The beneficial effect of the present invention is that, compared with the prior art, it solves the problem of high labor intensity and the need for maintenance personnel to climb on the insulator string to perform zero measurement piece by piece in the prior art insulator zero measurement devices, which is extremely dangerous. It also solves the technical problem that the existing technology of using drones for insulator zero measurement is immature and many zero measurement scenarios are in drone-free zones, making drone zero measurement impossible. Through innovations in structure and usage methods, the present invention improves the efficiency of insulator zero measurement and reduces the danger of insulator zero measurement work, thus having extremely high practical value.
