Abstract

The invention discloses an overheat fault monitoring device for a valve side sleeve of a converter transformer. The overheat fault monitoring device comprises an SO2 detection head, a processing module, a battery, a GSM module and a mobile terminal, wherein the battery is used for supplying power to the SO2 detection head and the processing module; the SO2 detection head is directly arranged in agas chamber of the valve side sleeve through a flange opening in the gas chamber of the valve side sleeve, and used for detecting whether SO2 gas exists in the gas chamber or not; the processing module is arranged on an outer wall of the valve side sleeve and connected with the SO2 detection head through a cable, and establishes a communication connection with the mobile terminal through the GSM module; a detection result is sent to the mobile terminal through the GSM module; and the mobile terminal is used for receiving the detection result, and judging the location of a failed sleeve. The overheat fault monitoring device for the valve side sleeve of the converter transformer disclosed by the invention is used for realizing overheat fault monitoring of the valve side sleeve of the converter transformer, and timely reporting an abnormal state to operation and maintenance personnel to provide a basis for the corrective maintenance of the valve side sleeve, so that the operation and maintenance personnel can timely know the position of the failed valve side sleeve, and timely perform operation and maintenance.

Description

technical field [0001] The invention relates to the technical field of overheating fault monitoring of a valve side bushing of a converter transformer, in particular to a valve side bushing overheating fault monitoring device and a monitoring method of a converter transformer. Background technique [0002] The converter transformer and its valve-side bushing are important equipment for the interface between the converter and the inverter in the AC and DC transmission systems. Because they have to withstand the joint action of the AC electric field, DC electric field and magnetic field, they are required to have high reliability. and high technical performance. With the increase of DC transmission capacity and voltage level, compared with other primary equipment in the converter station, the valve side bushing is more prone to failure, which also puts forward higher requirements on the manufacturing level and operation reliability of the valve side bushing. During the operat...
