Abstract

The invention discloses a combustion test apparatus for oil-immersed power transformers. The combustion test apparatus comprises a combustion test stand unit, for combusting an oil-immersed power transformer, including an igniting disc for combusting a tested wood stack and a transformer support, a combustion test room unit including an oil collecting pool, a firewall and a transformer combustion test room, an oil-water separating pool arranged inside and outside the transformer combustion test room for separating oil and water, a square water ditch which is arranged outside the transformer combustion test room, communicates with the oil-water separating pool to store water generated from oil and water separation during a fire extinguishing process, and a fire extinguishing protection unit including a water spraying fire extinguishing apparatus for extinguishing fire. The apparatus further comprises a state quantity monitoring unit for monitoring the temperature, heat radiation and pressure index during an oil-immersed transformer combustion process, a power supply unit for supplying power to the oil-immersed transformer, and a camera monitoring holder.

Description

technical field [0001] The invention relates to the field of combustion tests, and more particularly, to an oil-immersed power transformer combustion test device. Background technique [0002] At present, most of the transformers owned by power grids and industrial and mining enterprises are oil-immersed power transformers. Compared with dry-type transformers, oil-immersed power transformers are filled with insulating oil, which has the risk of explosion and fire, which will damage the surrounding equipment, buildings and Personnel harm, resulting in power outages and major economic losses. [0003] The mineral insulating oil used in the current oil-immersed power transformers has a flash point of about 140°C, which is flammable and explosive; the flash point of natural ester insulating oils such as synthetic esters exceeds 250°C, especially the natural ester insulating oil. The flash point exceeds 300°C, which belongs to the flame retardant fuel. Whether oil-immersed powe...
