Abstract

The invention provides a transformer fault simulating device which comprises three transformers. The first transformer comprises a plurality of high-voltage winding sleeve pipes, and terminals of the high-voltage winding sleeve pipes are connected to different positions of high-voltage winding coils respectively. Fastening bolts used for adjusting the height of a high-voltage winding are arranged between an upper insulation coil and an iron core and the lower insulation coil of the iron core of the second transformer, and supporting bars used for enabling the high-voltage winding to protrude outwards and a low-voltage winding to concave inwards are arranged between the high-voltage winding and the low-voltage winding. The third transformer is used for simulating winding warping faults. The three transformers are independent from one another, and the complex faults of short circuits, displacement, warping and bumps can be simulated simultaneously.

Description

technical field [0001] The invention relates to the field of transformer detection, in particular to a transformer fault simulation device. Background technique [0002] Since the beginning of the 21st century, along with the great economic development, the standard of living of the people has also reached a new level, and correspondingly, people’s demand for various electrical equipment is also higher and higher, which prompts the power system to accelerate its own development. building. [0003] In power system, transformer is one of the expensive and important equipment. With the continuous improvement of the voltage level, the probability of transformer failure is getting higher and higher, and once a failure occurs, it will cause a large-scale and long-term power outage in an area, causing major economic losses and great inconvenience to life. According to relevant statistics in recent years, the accidents caused by windings of 110kV and above transformers in the coun...
