After the urban subway trains have been in operation for a period of time, the transformer components in the subway train’s power supply system, namely the windings, leads, and insulation terminals, need to be cleaned, maintained, and repaired at regular intervals.

After the urban subway trains have been in operation for a period of time, the transformer components in the subway train’s power supply system, namely the windings, leads, and insulation terminals, need to be cleaned, maintained, and repaired at regular intervals.

During daily operation, subway transformers are exposed to complex environmental conditions including humidity, dust, and temperature fluctuations. Under electrical stress, partial discharge may occur, leading to carbonization on winding surfaces, which significantly reduces insulation performance. If not addressed in time, this degradation can increase the risk of transformer failure, potentially causing service interruptions or safety incidents.

To prevent transformer failures from causing train stops or unexpected situations, regular cleaning and maintenance are crucial. Moreover, restoring the insulation performance of transformer components is of paramount importance. After the subway transformers are cleaned, they are dried for several hours and then immersed in resin, which allows the surfaces of all components of the transformer to form an insulating shield again, ensuring performance. The traditional manual cleaning of transformer disassembly and maintenance is inefficient, ineffective, and labor-intensive. The transformer cleaning machine produced by Shanghai Tianshi, combined with special agents, can be started with one click and perform intelligent cleaning. It can quickly and effectively remove surface stains and meet the requirements for transformer maintenance and repair cleaning.
