Description
Technical field
The disclosure relates generally to transformer technology field, is specifically related to energy-saving oil immersed transformer technical field, particularly relates to the radiating tube anti-oil leakage mechanism of energy-saving oil immersed transformer.
Background technology
The radiating tube of oil-filled transformer is normally made through punching press with after seamed steel pipe flattening, often produce oil leakage phenomenon at radiating tube sweep and welding portion, this is because during punching press radiating tube, the outer wall of pipe is by tension force, its inwall is stressed, and exists caused by residual stress.Common way is that attendant is by regular inspection, once discovery oil leakage phenomenon, upper and lower for radiator panel valve (butterfly valve) is closed, oil in radiating tube and the oil in casing are cut off, reduce pressure and leakage, carry out suitable surface treatment after determining seepage place, then adopt encapsulant to carry out encapsulation process.This can increase the workload of attendant's inspection undoubtedly, easily produces blind spot in addition, not reliably when patrolling.
Summary of the invention
In view of above-mentioned defect of the prior art or deficiency, expect the radiating tube anti-oil leakage mechanism that a kind of energy-saving oil immersed transformer is provided.
The invention provides a kind of radiating tube anti-oil leakage mechanism of energy-saving oil immersed transformer, include radiating tube, flow sensor is provided with in radiating tube, be used for detecting changes in flow rate in radiating tube, the two ends that radiating tube is being connected with transformer-cabinet are separately installed with electromagnetically operated valve, also comprise a controller, controller be electrically connected with flow sensor, electromagnetically operated valve respectively.
The radiating tube anti-oil leakage mechanism of energy-saving oil immersed transformer provided by the invention, be provided with the flow sensor for detecting changes in flow rate in radiating tube in radiating tube, when radiating tube is without leakage of oil, the insulating oil of its inside keeps static, relatively without changes in flow rate; During radiating tube generation leakage of oil, the insulating oil of its inside can flow, and flow sensor gathers changes in flow rate information, by information feed back to controller, controls shut electromagnetic valve by controller, cuts off radiating tube and is communicated with the inside of transformer-cabinet.Compared with conventional art, the radiating tube anti-oil leakage mechanism of energy-saving oil immersed transformer provided by the invention has following beneficial effect:
1, avoid a large amount of losses of oil mass in oil-filled transformer, realize energy-conservation, also avoid the reduction of oil-filled transformer cooling effect.
2, be convenient to directly to search leakage of oil point after attendant is on the scene and implement leak stopping, alleviate workload, high efficient and reliable.
