A kind of oil volume compensating transformer

Abstract

The invention discloses an oil quantity compensation type transformer, which belongs to the technical field of power supply equipment, and comprises a transformer box body, the transformer box body has an oil chamber for containing transformer oil, a compensation oil tank is arranged on the top of the transformer box body, and the sampling port is fixedly installed There is a fixed pipe, the fixed pipe runs through the oil chamber of the transformer box and the end is fixed on the transformer box, an oil inlet gap is arranged on the fixed pipe located in the oil chamber, and the extension direction of the oil inlet gap is consistent with the extension direction of the fixed pipe , an isolation tube is installed in the oil inlet pipe, and an oil passage groove corresponding to the oil inlet gap is arranged on the isolation tube. A sampling tube is inserted in the isolation tube. corresponding exposure. The invention can collect oil samples at multiple positions at the bottom of the transformer, improves the accuracy of oil sample collection, and avoids transformer oil loss in the oil cavity caused by oil sample collection, and is widely used in power supply systems.

Description

technical field [0001] The invention relates to the technical field of power supply equipment, in particular to an oil quantity compensation type transformer. Background technique [0002] Transformer is one of the indispensable important equipment in the substation, and transformer oil is an indispensable chemical oil in the transformer, which is mainly used for internal insulation and heat dissipation of various oil-immersed transformers, as well as various oil circuit breakers and transformer substations. According to regulations, the arc extinguishing of connected switches needs to be sampled and analyzed every quarter to monitor the acidity, particle size, viscosity, sulfur and copper ion content of the oil, etc. A difficult problem for operation and maintenance personnel. At present, the traditional oil extraction method is to directly use an open glass container to take oil from the oil discharge valve hole of the high-altitude transformer, but this sampling method c...

Problems solved by technology

At present, the traditional oil extraction method is to directly use an open glass container to take oil from the oil discharge valve hole of the high-altitude transformer, but this sampling method can only collect oil samples near the oil discharge valve position, and oil samples far away from the oil discharge valve position cannot be collected. collection, resulting in distortion of the oil sample, and there is also a large amount of oil discharged, resulting in lack of oil in the oil chamber of the transformer, which makes the upper part of the oil chamber form a vacuum negative pressure area, which affects the normal use of the transformer
