Abstract

The invention discloses a high-frequency high-power supply operation monitoring and controlling system for electric precipitation. The high-frequency high-power supply operation monitoring and controlling system comprises a low-voltage side parameter detection module, a high-voltage side parameter detection module, a temperature detection module, a communication module and a monitoring and controlling center, wherein the low-voltage side parameter detection module is used for detecting the operation parameters of an input power supply at the high frequency side; the high-voltage side parameter detection module is used for detecting the operation parameters secondarily output by a transformer; the temperature detection module is used for detecting the transformer oil temperature parameter of the power supply and the temperature parameter of an IGBT radiator; the communication module is used for sending the parameter data detected by the modules to the monitoring and controlling center; the monitoring and controlling center is used for displaying he detected parameter data in real time and storing the data on a storage module for calling. The system can be used for monitoring and controlling the operation parameters of the power supply in real time, so that the workers can conveniently know the operation conditions in time and clear the faults; meanwhile, the system is provided with the storage module which is convenient to call the history data, is used for judging the possible fault causes and has the effect of alarming automatically, so that the troubles and the labor are saved.

Description

technical field [0001] The invention relates to a monitoring system, in particular to an operation monitoring system of a high-frequency, high-voltage, high-power power supply for electric dust removal. Background technique [0002] In view of the increasingly serious air pollution, the dust removal treatment of flue gas in the production process of thermal power plants, steel, metallurgy, papermaking, cement, chemical industry and other industrial fields has become an indispensable part of the industry. Therefore, for dust removal treatment, especially It is the power supply of the electrostatic precipitator that puts forward higher requirements to meet the needs of high flue gas temperature and high pressure required by the power supply. Reaction has become a new research direction of high-frequency high-voltage high-power power supply for electrostatic precipitator. Contents of the invention [0003] In view of the defects existing in the prior art, the object of the p...
