Problems solved by technology

[0002] Oil-immersed transformer oil discharge and nitrogen injection fire extinguishing equipment is used as a transformer protection device. It realizes explosion-proof, fire prevention and fire extinguishing of transformers by means of oil discharge, pressure relief and nitrogen filling cooling. It has been widely used in the field of transformer fire protection. Therefore, the oil recovery device is a It is an important transformer component. In the existing oil recovery device, the high-temperature hot oil and mixed combustible gas on the top layer of the transformer discharged from the oil discharge and nitrogen injection fire extinguishing equipment are collected into the transformer oil pool or open container through the pipeline of the fire cabinet. Oil and combustible gas are still flammable when they come into contact with oxygen. At the same time, they pollute the environment and are not conducive to the secondary recovery of oil. If they are discharged into the container, they will cause the accumulation of combustible gas and there is a risk of explosion. There is no one based on oil.

Abstract

The invention provides an oil recovery device and method based on linkage of oil discharge and nitrogen injection fire extinguishing with an oil immersed transformer. The oil recovery device comprisesa casing (1) having an accommodating cavity, an oil conveying pipe (2) arranged between the casing (1) and a transformer oil conservator, and a shut-off valve device (3) that is arranged on the oil conveying pipe (2) and is opened on the basis of a defined pressure of the oil of the transformer oil conservator, the high-pressure oil in the transformer oil conservator is injected into the casing (1) through the oil conveying pipe (2) by opening the shut-off valve device (3), the casing (1) stores the oil, and the high-temperature hot oil at the top layer of the transformer and mixed combustible gas discharged from the oil discharge and nitrogen injection fire extinguishing equipment are not collected in a transformer oil pool or an open container through a fire prevention cabinet pipeline,therefore the oil is centrally stored and can be conveniently recovered.

Description

technical field [0001] The invention relates to an oil recovery device and method, in particular to an oil recovery device and method based on linkage with oil discharge and nitrogen injection of an oil-immersed transformer for fire extinguishing.
