Full-automatic flushing device and flushing method for gilled radiator of transformer

Abstract

The invention relates to a full-automatic flushing device for a gilled radiator of a transformer. The device includes an all-in-one machine control cabinet and a flushing pipeline, wherein the all-in-one machine control cabinet is provided with a touch screen and a PLC device, the flushing pipeline is used for connecting an oil storage tank to the gilled radiator and consists of an oil pump, electric valves, electric ball valves, manual ball valves, manual butterfly valves, a coarse filter and fine filters, the oil pump driving oil to flow in the pipeline, the electric valves and the electricball valves are electrically connected with the PLC device through cable accessories, and the PLC device is provided with a control module and a display module. The invention further relates to a full-automatic flushing method for the gilled radiator of the transformer. According to the device and the method, a travelling crane and an oil filter are not occupied for a long time, the large-flow oilpump is used for achieving automatic flushing, and the working efficiency is improved; ten sets of gilled radiators different or same in specification can be flushed at the same time, and qualified flushing oil is provided by the special oil tank. The flushing device can cooperate with an existing oil filter and a large-capacity flushing device in use, independent automatic flushing and filteringcan be achieved, and the working efficiency is improved.

Description

technical field [0001] The invention belongs to the technical field of transformer operation and maintenance, and in particular relates to an automatic flushing device and flushing method for transformer chips. Background technique [0002] Transformer fins, usually referred to as transformer fins. Welding slag, dust and other debris in the transformer chip are not easy to clean. Due to the complex internal structure of the transformer, once the impurities enter the transformer, it is not easy to wash out, which can easily cause partial discharge or even breakdown. [0003] At the same time, since the impurities inside the transformer chips will pollute the transformer oil, it is necessary to prolong the oil filtration time of the oil filter, and the ultra-ultra-high voltage products also need to be deeply cleaned with special high-flow washing equipment, resulting in prolonged construction period, labor, material consumption and energy consumption. waste.

AI Technical Summary

Problems solved by technology

Welding slag, dust and other sundries in the transformer sheet are not easy to clean. Due to the complex internal structure of the transformer, once the impurities enter the interior of the transformer, it is not easy to wash out, which can easily cause partial discharge or even breakdown.

[0003] At the same time, since the impurities inside the transformer fragments will pollute the transformer oil, it is necessary to prolong the oil filter cycle oil filter time, and ultra-UHV products also need to be deeply cleaned with special large-flow washing equipment, resulting in extended construction period, labor, material consumption and energy consumption. waste

[0004] At present, it mainly depends on transformer chip manufacturers to wash before leaving the factory. For users, the quality of washing is difficult to supervise and guarantee.

[0005] In addition, the flakes of important products are currently connected to the pipeline of the oil filter, and the flakes are hoisted by the crane for washing, which takes up the oil filter, takes a long time to drive, is time-consuming and laborious, and the flushing effect is not easy to monitor
