Description

Technical Field

[0001] The invention relates to the technical field of power supply safety, and in particular to an insulation detection device for a power circuit. Background Art

[0002] Insulation testing of power circuits refers to the testing and evaluation of the insulation performance of various equipment and lines in the power system to ensure that electrical equipment will not cause dangers such as short circuits, leakage or electrical fires due to insulation failures during operation. This process is crucial to ensuring the safety, stability and reliability of the power system. Therefore, when the equipment or cables in the power circuit are in long-term operation, it is necessary to arrange for inspection personnel to conduct insulation testing on them regularly.

[0003] At present, when conducting daily insulation testing on power circuit equipment or cables, it is usually done by staff manually holding testing instruments (such as insulation resistance meters, infrared thermal imagers, ground resistance testers, etc.). This testing method still has the following shortcomings in actual operation: 1. When using a handheld testing instrument for testing, the tester needs to hold the testing equipment in one hand, which makes it impossible for the tester to operate the positive and negative test pens with one hand for testing. The tester often needs to put the testing equipment aside before testing. This method can easily cause problems such as electric shock, short circuit or collision damage of the testing equipment; 2. The detection pens of existing detection equipment are all of a length that is convenient for detection personnel to grasp. This means that when testing power circuit equipment, detection personnel need to hold the detection pen in contact with the equipment, and the distance between the staff and the power circuit equipment is short, which poses certain safety hazards; 3. When testing the equipment or cables of the power circuit, the staff often need to bend down or climb according to the testing needs, which brings great inconvenience to the testing work of the testers; 4. When performing insulation testing on cables in power circuits, existing testing pens can only perform contact testing on a single point, which cannot meet the insulation testing needs of cables; Therefore, there is an urgent need for an insulation detection device that can overcome the above-mentioned shortcomings. Summary of the invention

[0004] In order to overcome the shortcomings of the background technology, the present invention discloses an insulation detection device for a power circuit. The present invention, through the cooperation of a support member and an insulating rod, not only does the insulation detection efficiency need not bend down, squat or climb by the detection personnel, which greatly improves the insulation detection safety of the detection personnel.
