Description

Technical Field

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

[0002] In order to ensure the safe operation of transmission lines and the safety of personnel during live operations, porcelain insulators need to be inspected. First, during the power outage of the line for maintenance, maintenance personnel need to hold a resistance tester to test each insulator one by one. Not only is the labor intensity high, but climbing on the insulator string to measure zero piece by piece increases the danger. Second, before entering the electric field during live operations, maintenance personnel hold the insulating operating rod and use the spark gap method or voltage distribution method to measure zero. The zero measuring device is installed on the top of the insulating operating rod. The operator needs to use himself as a fulcrum, hold the end of the insulating operating rod, and lift and lower each piece to measure zero, which is time-consuming and labor-intensive, and the labor intensity of the operator is high. When measuring the insulator on the conductor side, the insulating operating rod cannot be lifted up for zero measurement due to the long distance, or the maintenance personnel's body and arms lean forward, which can easily lead to short-circuiting of some insulators, resulting in insufficient safety distance and causing danger.

[0003] Although there are some technologies for detecting zero-value insulators by drones, 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 gate-type frame insulator strings in the inspection station is still required; a large number of transmission lines cross jungles and mountainous areas, where signals are sparse and obstacles are numerous, and drones do not have the conditions for autonomous flight; some lines are in no-fly zones for drone aviation control, and drones cannot take off. Summary of the invention

[0004] In order to solve the deficiencies in the prior art, the present invention provides an insulator string rapid zero detection device and a method for using the device.

The triangular clamp string wheel of the driving structure moves on one side of the insulator string, and the bar slider is slid onto the insulator string to drive the detection structure to work. The zero measuring instrument probe of the detection structure falls onto the steel caps on both sides of the single-piece insulator to measure the zero of the insulator.

[0021] Preferably, during use, when the triangular card string wheel slides to above the insulator, the triangular card string wheel falls down and drives the connecting rod steering gear to rotate, the connecting rod steering gear drives the Z-type steering gear to rotate, the Z-type steering gear drives the auxiliary connecting rod and the resistance rod to rotate, and the resistance rod drives the zero measuring instrument probe to rotate and fall above the insulator, and no zero measurement is formed.

[0022] The beneficial effect of the present invention is that, compared with the prior art, it solves the problem that the maintenance personnel in the prior art insulator zero measurement device have high labor intensity and need to climb on the insulator string to measure zero piece by piece, which is extremely dangerous.

DETAILED DESCRIPTION

[0031] In order to make the purpose, technical scheme and advantages of the present invention clearer, the technical scheme of the present invention will be clearly and completely described below in conjunction with the 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 creative work 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, 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 a 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, and the two groups of strip sliders 3 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 connecting end of the triangular card string wheel 2-1 is connected to the connecting rod steering gear 2-2, and the other connecting end is suspended.

[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 outer side 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 of the zero measuring instrument probes 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 arranged at the top by a set distance, and the two zero measuring instrument probes have 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. The triangular clamp 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 rod forward, the triangular card string wheel 2-1 slides over the insulator to reach between the insulators A-2 and A-3, and the triangular card string wheel 2-1 falls down, driving the connecting rod diverter 2-2 and the Z-type diverter 2-3 to be transmitted to 4-1, and the probe of the zero measuring instrument falls on the steel caps of A-1 and A-2 to form zero measurement;

[0048] When the triangle card string wheel 2-1 slides to the top of the insulator A-2, the triangle card string wheel 2-1 falls down, drives the connecting rod diverter 2-2 and the Z-type diverter 2-3 to be transmitted to the zero measuring instrument probe 4-1 to fall 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 to measure the zero of insulators is that it is not easy for workers to walk under the tower, such as in deep mountains, forests, isolated islands and other environments. The drone's rapid maneuverability can be used to fly near the insulator for testing. This reduces the risk of workers climbing mountains and wading through water, and also improves the timeliness of the work. The disadvantage is that when operating drones for long-distance testing, the unclear field of view, the interference of electromagnetic fields on wireless communication equipment, and external factors in the natural environment will also interfere with the safety of drone flight. The risk of "explosion" will also bring risks to power lines.

[0050] Manual use of an insulator zero measuring device for zero measurement has the following advantages in a relative environment:

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

[0052] 2. To ensure the safety of personnel from a safety perspective, 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 that the maintenance personnel in the prior art insulator zero measurement device have high labor intensity and need to climb on the insulator string to measure zero piece by piece, which is extremely dangerous. It also solves the technical problem that the existing technology of using drones to measure zero of insulators is immature, and there are many zero measurement scenes that are drone no-fly zones, so drones cannot be used for zero measurement. The present invention improves the work efficiency of insulator zero measurement and reduces the danger of insulator zero measurement work through innovations in structure and use method, and has extremely high practical value.
