Description

Technical Field

[0001] The present application relates to the technical field of power transformer detection, and in particular to a power supply system with automatic protection function for power transformer detection. Background Art

[0002] Considering the needs of economic operation, a large number of old transformers are still in service in the domestic power system. The service life of transformers is generally no more than 30 years, but in reality, transformers over 30 years old are still in operation. How to grasp the health of these old transformers and evaluate the insulation aging of transformers is the key. The internal insulation of oil-paper insulated transformers is composed of oil and paper. The oil can be replaced and regenerated during operation, while the aging of paper insulation is irreversible. Therefore, the aging of oil-paper insulated transformers is actually the aging of paper insulation. At present, the most effective method to analyze and judge the aging of paper insulation is to detect the polymerization degree of insulating paper. When performing the detection operation, power supply equipment is required to power the detection device.

[0003] The existing power supply device simply connects the connection of the power supply device with the connection of the power transformer. The connection has no protection and is prone to high-temperature overload. High-temperature overload is prone to short circuit, which poses a safety hazard. In addition, some power supply equipment needs to be moved to a suitable position, is not easy to move, and has low stability when fixed, which reduces the use value of the power supply equipment and has certain defects.
