Fire extinguishing and oil recovery device for oil-immersed transformer or oil storage tank

Abstract

The invention relates to a fire extinguishing and oil recovery device for an oil-immersed transformer or an oil storage tank. The problems are solved that the design is not reasonable enough and the like in the prior art. The device comprises a transformer body oil tank, one side of the upper end of the transformer body oil tank is provided with a transformer oil conservator through an oil supplementary on-off structure, the other side of the upper end of the transformer body oil tank is provided with a transformer oil discharge port, the transformer oil discharge port is connected with an oildischarge pipeline which is connected with a connection pipe through an oil discharge mechanism, the connection pipe is provided with an observation window and an oil leakage feedback device, the connection pipe is connected with an oil collection box, the oil collection box is internally provided with an oil collection cavity, the outer side of the oil collection box is provided with an oil level meter, the connection pipe communicates with the oil collection cavity, the lower end of the oil collection box is provided with an oil discharge valve, the upper end of the oil collection box is provided with an air exhaust pipe, and the air exhaust pipe is provided with a check valve. The special oil collection box is additionally arranged to achieve a discharged oil recovery function, is convenient to construct, protects the environment and greatly reduce the recovery and cleaning cost after fire extinguishing.

Description

Technical field [0001] The invention belongs to the technical field of power supply equipment, and particularly relates to a fire extinguishing and oil recovery device for an oil-immersed transformer or an oil storage tank. Background technique [0002] The transformer oil drain and nitrogen injection fire extinguishing device is introduced from French technology and has been used in my country for more than 30 years. GA 835-2009 "Oil-immersed transformer oil drain and nitrogen injection fire extinguishing device" and CECS187: 2005 "Oil-immersed transformer oil drain "Technical Regulations for Nitrogen Injection Equipment" and other relevant national industry standards, and have been included in national compulsory certification products in recent years. The application principle and control technology of the product have been greatly improved and changed. However, most of the current market considers the fire-fighting function of this type of product, and lacks environmental pro...

AI Technical Summary

Problems solved by technology

[0004] The above scheme solves to a certain extent the problem that the existing transformer oil discharge and nitrogen injection fire extinguishing device easily discharges the oil-air mixture into the accident oil pool and ignites the accident oil pool, but this scheme still exists: it is impossible to realize the centralized recovery of transformer oil poles, etc. question
