Converter transformer fire fighting monitoring system and method

Abstract

The invention provides a converter transformer fire monitoring system and method. The converter transformer fire fighting monitoring system comprises a converter transformer fixed fire-fighting system, a fire alarm controller, a converter transformer alternating-current side circuit breaker, a temperature sensing detector and a flame detector, wherein the fire alarm controller and the converter transformer alternating-current side circuit breaker are electrically connected with the converter transformer fixed fire fighting system, the temperature sensing detector is connected with a convertertransformer body and outputs the temperature signal to the fire alarm controller, and the flame detector is used for detecting the flame signal sent by the converter transformer and outputs the flamesignal to the fire alarm controller. According to the system and method, the corresponding alarm signals are output to the converter transformer fixed fire-fighting system through the fire alarm controller and the converter transformer alternating-current side circuit breaker, and finally, whether the converter transformer fixed fire-fighting system is started or not is judged, so that the fire can be timely extinguished when the converter transformer occurs the fire, and the outstanding advantages of effectively improving the anti-misoperation reliability of the converter transformer fire-fighting system and the like are achieved.

Description

technical field [0001] The invention relates to the field of converter transformer fire protection monitoring, in particular to a converter transformer fire protection monitoring system and method applied to UHV DC converter stations. Background technique [0002] The converter of the UHV DC converter station becomes a forced oil circulation transformer, which belongs to oil-filled equipment. It is in the operating condition of high power and high current for a long time, and it is the electrical equipment most prone to fire in the converter station. [0003] When a fire breaks out in the converter, it is necessary to start the fire protection system as soon as possible to prevent the fire from spreading and reduce the fire loss. However, since the fire-fighting system is started, the fire-fighting facilities in it have a great impact on the electrical equipment, which may lead to scrapping of the converter. Therefore, it is particularly important for the anti-misoperation ...
