Structure and characteristics of explosion-proof tubes for oil immersed transformers
The explosion-proof tube of an oil immersed transformer is a device used to protect the oil immersed transformer. Its main structure and characteristics are as follows:
1. Structure: The explosion-proof tube of an oil immersed transformer is composed of a tube body, flange, baffle, and other parts. The pipe body is usually made of seamless steel pipes or alloy steel pipes, and it is filled with refractory materials inside to prevent the splashing and combustion of oil immersed transformers from entering the pipeline during a fire. The flange connects the pipe body and transformer box, and the baffle can block the contact between the internal gas of the transformer and the external environment.
2. Features: The explosion-proof tube of the oil immersed transformer has the following characteristics:
(1) Good explosion-proof performance: The body and accessories of the explosion-proof tube are all made of pressure resistant and explosion-proof materials, which can effectively prevent fire accidents.
(2) Strong corrosion resistance: explosion-proof pipe material can work in various harsh environments, and will not be corroded due to the pollution of transformer oil.
(3) Easy installation: The explosion-proof pipe is connected with a flange, which is simple and convenient to install, and can be disassembled repeatedly.
(4) Economical and practical: The explosion-proof tube can be customized in size and materials according to actual needs, with low cost, good performance, and stable long-term use effect.
The explosion-proof tube of an oil immersed transformer is an important safety protection device that can improve the safety performance of the transformer and avoid the occurrence of fire accidents
