A transformer test device

Abstract

The invention discloses a transformer test device, which comprises a bottom plate, support rods are fixed on the four corners of the surface of the bottom plate, and a top plate is installed on the top of the support rods, an adjustable frame is installed on the surface of the bottom plate, and the outside of the adjustable frame is fixed and useful. For adjusting the adjusting device of the adjustable frame, the present invention realizes the combination of a sealed rectangular cavity through the bottom plate, the top plate and the adjustable frame, and then realizes the adjustment of its size through the adjusting device, so as to meet the use of transformers of different shapes, the top plate The installed collection device realizes the collection of gas due to pyrolysis in the closed rectangular cavity, and through the external gas analysis equipment, the analysis of the gas is realized, so as to determine whether the transformer is up to standard.

Description

technical field [0001] The invention relates to the technical field of transformer testing, in particular to a transformer testing device. Background technique [0002] With the vigorous development of China's electrical technology, more and more electrical equipment has been widely used. After leaving the factory, handover or overhaul of electrical equipment, an AC temperature rise test should be carried out to actually assess the overcurrent withstand capacity of the equipment. Most power transformers are oil-immersed structures, and their main insulating media are insulating oil and insulating paper. To the internal insulation and heat dissipation of the transformer, the latter plays the role of insulation and support, and the oil-paper insulation system is an important factor to ensure the safe operation of the transformer. [0003] When the oil-immersed transformer in operation is subjected to abnormal heat and electric field, it will cause the insulation oil to decomp...

Problems solved by technology

[0004] The existing transformer fault simulation system simulates the thermal fault of the transformer and analyzes the gas generated by the transformer. Since the gas escape is not considered, the detection results cannot accurately reflect the gas production law of the insulating oil caused by the fault, and different transformer sizes Different body shapes make it impossible to effectively test different types of transformers, resulting in a low range of use. For this reason, we propose a transformer test device
