Description
TECHNICAL FIELD
[0001] The utility model relates to the technical field of electric power detection, and particularly relates to a partial discharge detector with wire harness storage function. BACKGROUND
[0002] The partial discharge detector is also called partial discharge detector, which is an instrument for detecting partial discharge in electrical equipment. Partial discharge refers to the discharge phenomenon occurring in the local area of the insulation system of electrical equipment due to uneven electric field distribution, internal defects (such as bubbles, impurities) of the insulation material, or weak points of the insulation system. However, it has not yet penetrated between the electrodes. Partial discharge gradually erodes the insulation material, and long-term accumulation may lead to a decrease in insulation performance, eventually causing insulation breakdown and triggering electrical equipment failure. This not only causes equipment damage, but also may cause power failure accidents, affecting the normal operation of the power system. Therefore, it is necessary to regularly detect partial discharge.
[0003] When partial discharge occurs in electrical equipment, part of the energy is radiated in the form of ultraviolet light. Using a detector sensitive to ultraviolet light, the ultraviolet signal generated by partial discharge can be captured. Through these signals, partial discharge can be converted into an image for display.
[0004] However, in practice, it has been noticed that the wire between the processing circuit of the partial discharge detector and the detector is relatively long. When storing, the wire is generally wound outside the instrument. Friction easily occurs at the corner of the wire and the instrument. Long-term friction can cause damage to the insulation layer on the outside. When using the storage roller to store the wire, the connection between the wire and the instrument cannot rotate, which can easily cause the wire to be subjected to circumferential shear force, thereby causing damage to the connection of the wire.
