Oil charging device oil permeating point positioning detector and using method thereof

Abstract

The invention discloses an oil charging device oil permeating point positioning detector and a using method thereof. The oil charging device oil permeating point positioning detector comprises an insulating rod body and an insulating box body arranged at the top end of the insulating rod body. An electric insulating brush head and a camera are connected to a side plate of the insulating box body, and a plurality of automatic sprayers are arranged inside the insulating box body. A motor is arranged inside the insulating rod body, and switch buttons with different gears are arranged at the lower end of the insulating rod body. The using method comprises the steps of preparing mist spray solvent, rinsing greasing, spraying penetrant, washing the penetrant, spraying white photographic developer, photographing and positioning oil permeating points. By means of the structure and the method, an electrically charged device does not need to be turned off, a user only needs to stand on the ground and turns on the switch buttons of the corresponding gears, then, cleaning agents are automatically sprayed, the electric insulating brush head cleans and scrubs, the penetrant and the white photographic developer are automatically sprayed and photographing is carried out on the oil permeating positions, an operator observes blackened and darkened points of the white photographic developer from a video or an image, and the points are the oil permeating points. Operation is easy and convenient, and the oil permeating points are positioned accurately.

Description

[0001] technical field [0002] The invention relates to a detection device used in a power system and a use method thereof, in particular to an oil-filled equipment oil seepage point location detector and a use method thereof. Background technique [0003] Oil-filled equipment such as transformers and transformers is the main equipment in the substation. After a period of operation, due to welding quality problems, poor sealing, and inaccurate oil leakage points, the oil-filled equipment will leak oil. The oil leakage of these equipment will affect the safe operation of electrical equipment, thus arousing great attention of the electric power industry. Because the oil seepage point is very small, how to accurately locate the oil seepage point is a difficult problem. [0004] There are mainly five original methods for finding oil seepage points: ①Eye observation method: Generally, where the wettest place is the oil seepage point, this method has a high misjudgment rate and ...

Problems solved by technology

[0004] There are mainly five original methods for finding oil seepage points: ①Eye observation method: Generally, where the wettest point is the oil seepage point, this method has a high misjudgment rate and is inaccurate

②Powdering method: apply chalk near the oil seepage point, and observe where it gets wet first to determine where the oil seepage point is. This method cannot find live equipment

③Water flushing method: It is suitable for finding the leakage point of the cooler pipe of the radiator of the strong oil circulation transformer; it is not versatile and is not suitable for searching for live equipment

④Touch test method: when checking, use hands or tools to touch from top to bottom, and you can find the leak point; maintenance is inconvenient and time-consuming, and it is also not suitable for searching live equipment

This invention is suitable for severe leakage and oil dripping. When the oil leakage point is small, it is not suitable for the leakage part without oil drop, which is easy to cause omission. In addition, the method is not accurate for oil leakage point search and needs assistance Other methods are used to further determine the oil seepage point
