Description

Technical Field

[0001] The invention relates to a counting device, more specifically to an automatic counting device for leaked oil. Background Art

[0002] In power substations, some oil-filled equipment, such as transformers, voltage transformers, high-voltage reactors, etc., are affected by the manufacturing process of parts, operating environment, installation quality, and years of operation. The flanges and gaskets at the connection of the parts are aging, and the welding points and welds of the steel plates have problems such as quality, which lead to oil leakage in the gaps. If the equipment leaks oil for a long time or leaks a lot of oil, there will be insufficient oil. When the oil level of the running equipment, especially the transformer, drops too much, it may cause the gas protection to malfunction. Secondly, it is easy for water to enter while leaking oil, causing the inside of the equipment to be damp. At the same time, the oil leakage part is very easy to adhere to dust, so that a large area of ​​oil is adhered to the surface, which greatly affects the appearance and brings difficulties to the maintenance work. Moreover, oil leakage wastes resources and pollutes the environment. In the operation and maintenance management of power equipment, according to the provisions of the "Standard Defect Library of Primary Substation Equipment of State Grid Corporation", we need to determine whether the oil leakage at this place belongs to "general defect", "serious defect" or "critical defect" according to the number of oil drops per minute of the equipment, so as to facilitate the maintenance personnel to further judge and deal with it. With existing detection methods, when oil leaks from a pipeline flange, the oil will drip at different locations on the flange, causing some of the dripping oil to be missed, resulting in inaccurate counting. Summary of the invention

[0003] The purpose of the present invention is to provide an automatic counting device for leaking oil, which can combine a guide box with a counter and a guide tube, so that the guide box can hold oil at different positions on the flange, and concentrate the oil dripping from the guide tube to the optical path between the transmitting end and the receiving end, thereby avoiding the easy leakage of part of the dripping oil and improving the accuracy of counting.
