The present application belongs to the technical field of generator equipment monitoring, and particularly relates to a method for preventing the sparking of a generator excitation brush. First, a monitoring module is arranged at the rotor excitation brush of the generator to obtain a digital switching signal and an analog signal of sparking frequency when the brush sparks. After the digital switching signal and the analog signal are preprocessed, it is determined whether the signal threshold is exceeded. If so, a de-excitation signal is generated. According to the de-excitation signal result, a solution is matched and pushed to the user. The present application can solve the problem of poor monitoring effect of the generator excitation system in the prior art.

This invention provides a collagen reaction vessel for easy observation of the reaction process, comprising a shell, an inner reactor body installed inside the shell, a transparent observation window mounted on the outer surface of the shell, and a high-definition camera mounted on the inner wall of the shell. The reactor body is made of quartz glass, and a ring-shaped cold light tube is mounted on the outer surface of the shell. The outer surface of the transparent observation window is coated with a nano-level anti-fog coating. The nano-level anti-fog coating on the outer surface of the transparent observation window effectively prevents fogging caused by temperature and humidity changes during the reaction, ensuring clear observation at all times and allowing operators to clearly capture details of the reaction process. The high-definition camera mounted on the inner wall of the shell breaks through the limitations of traditional single-view observation and eliminates blind spots; the reactor body, made of quartz glass, has excellent light transmittance, which, combined with the high-definition camera, enables comprehensive monitoring of the overall reaction process within the reactor.
