Description

Technical Field

[0001] This application relates to the field of insulating tool technology, and in particular to an insulating performance testing device for insulating tools. Background Technology

[0002] Insulating tools are among the most commonly used protective tools, playing a crucial role in personal safety. They are widely used in industries such as power, petrochemicals, machinery manufacturing, and construction. However, the problem of insulating tools being shipped out with defects is common, leading to numerous personal injuries and deaths among workers. Therefore, it is essential to conduct insulation performance testing on insulating tools before they leave the warehouse.

[0003] However, before leaving the warehouse, the insulation performance of insulating tools must be measured using a 2500V megohmmeter. To ensure testing accuracy, the electrode width and electrode spacing are usually set to fixed values ​​during the insulation performance testing process. The insulation performance testing methods for insulating tools can be divided into overall measurement and segmented measurement. Since the overall measurement requires an effective insulation section of no less than 10,000 megohms, which the megohmmeter's range cannot accurately measure, segmented measurement (requiring an effective insulation section of no less than 100 megohms) is typically used to test the insulation performance of insulating tools. During segmented measurement, the operator needs to wear insulating gloves and hold both electrodes separately, sliding the electrodes along the effective insulation length of the insulating tool while shaking the megohmmeter. It is difficult to ensure that the electrode spacing is exactly the required value during this process, resulting in lower accuracy of the insulation performance test results. Furthermore, the above operation is cumbersome and reduces the efficiency of insulation performance testing. Utility Model Content

[0036] Two electrode plates 200 with a preset width, the two electrode plates 200 are arranged in parallel on the mounting plate body 100 and are spaced apart by a preset distance, and the two electrode plates 200 are both provided with a connecting piece 201 capable of conducting electricity, and the two connecting pieces 201 are respectively connected with the free ends of two terminal 300 of the megohmmeter; wherein the specific values of the preset width and the preset distance can be set according to the specific situation in the actual detection process, and the application does not make specific limitations on the same. In addition, the two terminal 300 of the megohmmeter connected with the connecting piece 201 usually refers to the "L" end and the "E" end of the megohmmeter, and the purpose is to form a measurement loop. Since the preset width and the preset distance are both a certain value, the width of the electrode plate 200 and the distance between the electrodes in the above detection process are both determined, thereby ensuring the accuracy of the detection result of the insulation performance.

[0037] The handle 400 is sleeved on the mounting plate body 100, and is used to drive the two electrode plates 200 on the mounting plate body 100 to move along the insulation tool along with the shaking of the megohmmeter to detect the insulation performance of the insulation tool. Wherein, the handle 400 is arranged to be convenient for the operator to hold by hand, and compared with the prior art which needs the operator to hold one electrode with each hand, the present application only needs the operator to hold the handle 400 with one hand to realize the movement of the electrode plate 200 on the mounting plate body 100 along the insulation tool, and realizes the detection of the insulation performance of the insulation tool.

[0045] In some embodiments, the electrode plate 200 and the connecting piece 201 in the application are both made of copper material.

[0046] In the above embodiment, copper is used due to its good electrical conductivity, thermal conductivity and corrosion resistance, etc., to ensure the long-term effectiveness of the electrode plate 200 and the connecting piece 201 made of copper, and to effectively prevent lightning strikes and generate high potential fault currents, thereby protecting electrical equipment and personnel safety.
