Abstract

The invention relates to a convertor station high-voltage secondary screen cabinet infrared temperature measurement method. The method comprises the steps that a high-voltage secondary screen cabinet is measured through an infrared temperature measurement device; for all components on the high-voltage secondary screen cabinet, colors of different grades are used to represent different temperatures, and a typical temperature distribution diagram automatically generates; and according to the infrared temperature distribution diagram, the components of large heating value are measured, and at the same time overall measurement is carried out, thus abnormal points in a temperature measurement process can be quickly and timely found. Compared with the prior art, the convertor station high-voltage secondary screen cabinet infrared temperature measurement method provided by the invention has the advantages of high temperature measurement speed, high temperature measurement accuracy and the like.

Description

technical field [0001] The invention relates to a method for measuring the temperature of a high-voltage secondary screen cabinet, in particular to an infrared temperature measurement method for a high-voltage secondary screen cabinet of a converter station. Background technique [0002] The high-voltage electrical screen cabinet is in a fully enclosed operating environment for a long time. The connection parts of the relays in the operation cabinet will cause excessive contact resistance and heat due to poor production, transportation, installation and aging. If these heating parts cannot be monitored in time and effectively , if it is not repaired in time, it may affect the continuity and reliability of power transmission. In the accidents in recent years, there have been many cases of accidents caused by the failure of effective control of hot spots. Therefore, it is the key to prevent and prevent such accidents to discover and deal with abnormal temperature points during...
