Oil-water separation type emergency oil storage pool for transformer of 66kV substation

Abstract

The invention relates to an oil-water separation type emergency oil storage pool for a transformer of a 66kV substation. The oil-water separation type emergency oil storage pool is structurally characterized in that a baffle is arranged in the oil storage pool to divide the oil storage pool into an oil pool and a water pool, a water drain pipe and a water drain gate valve are installed between the oil pool and the water pool, and the oil pool and the water pool are respectively connected with an oil inlet pipe and a water outlet pipe. By adopting the oil-water separation type emergency oil storage pool, a good condition that the oil storage pool does not contain water throughout the year can be reached, the traditional methods of pumping the water by using a water pump and manually draining the water are abandoned and the labor intensity and the labor cost are reduced; and since the water is convenient to drain and the oil storage pool does not contain water in winter, the situation that the emergency oil storage pool is damaged due to water frost heaving is eliminated. Oil-water separation complies with requirements on safety, fire prevention and environmental protection, the economic benefit is great and thirty thousand Yuan can be saved every year. The operation reliability of the substation is improved and a reliable guarantee is provided for local industrial and agricultural production and household electricity use of people.

Description

technical field [0001] The invention relates to an electric equipment oil storage pool, in particular to a 66kV substation oil-water separation type transformer emergency oil storage pool. technical background [0002] In recent years, there are many new and expanded 66kV substations, whether it is a full-indoor substation or a semi-indoor substation. They are all related to the oil discharge problem of the transformer accident. Due to the requirements of fire protection and environmental protection, the oil discharged from the transformer accident cannot be directly discharged into the sewer network. In the prior art, the design of accidental oil discharge of transformers is to design an oil storage tank with no entry but no exit. Rainwater in the rainy season enters the oil storage tank through the connecting pipe from the transformer oil pit to the oil storage tank every year. Often the reservoir is full of water. In order to ensure the oil discharge of the transform...
