Problems solved by technology

However, at the power construction site, due to the limitations of the working environment, climate, temperature and humidity, dust, sampling containers, etc., this sampling method of exposed insulating oil often causes pollution and oxidation of the insulating oil, resulting in unsatisfactory test results. Even misjudgment occurs, and multiple sampling and inspections are often required, which not only wastes manpower, material resources, and time, but also repeatedly filters the insulating oil at high temperature, and may face passive situations such as deterioration of the insulating oil

Abstract

The invention discloses insulating oil sampling equipment which is convenient for quantitative oil sampling, comprising a sampling tube, a needle head, a sampling push-pull rod, a positioning connecting rod, a limit rod and a positioning nut, wherein the needle head is connected to the lower end of the sampling tube and connected to the inside of the sampling tube , the sampling push-pull rod is inserted into the sampling tube from the upper end of the sampling tube. The positioning connecting rod includes a horizontal connecting rod arranged horizontally and a vertical positioning rod arranged vertically. The two ends of the horizontal connecting rod are respectively fixedly connected with the side wall of the sampling tube and the lower end of the vertical positioning rod. , the number of positioning nuts is two, and the two positioning nuts are connected to the vertical positioning rod through thread matching. The other end is located directly above the sampling push-pull rod. When the invention is applied, sampling is convenient, clean and efficient, which is beneficial to accurate test results and can avoid repeated sampling tests.

Description

technical field [0001] The invention relates to the technical field of electric power construction, in particular to insulating oil sampling equipment for quantitative oil sampling. Background technique [0002] The testing process of electrical equipment will involve the sampling and testing of insulating oil. The current sampling method for insulating oil is to slowly open the valve on the sampling interface pipe first, use the sampling bottle to directly receive the insulating oil flowing out, and seal the sampling bottle after receiving the oil sample. Cover and bandage to prevent detachment can be sent for inspection. However, at the power construction site, due to the limitations of the working environment, climate, temperature and humidity, dust, sampling containers, etc., this sampling method of exposed insulating oil often causes pollution and oxidation of the insulating oil, resulting in unsatisfactory test results. Even misjudgment occurs, and multiple sampling a...
