Problems solved by technology

At present, the commonly used detection method is manual inspection. Hand-held infrared thermometers are used to measure the data in the power switch distribution cabinet. Because the structure of the power switch distribution cabinet is very complicated and the internal space is small, its internal components block each other so that the infrared The thermometer is often unable to obtain accurate temperature data, and the manual inspection time interval is long, and the temperature of the switch distribution cabinet cannot be measured in time, which may eventually lead to the burning of the switch distribution cabinet

Abstract

The invention provides a system for monitoring temperature of a switching distribution cabinet online. The system comprises a sensor, a monitoring device and an application device; the sensor is used for collecting temperature information of the switching distribution cabinet and converting the temperature information into optical information; the monitoring device is used for converting the optical information into a digital signal and warning on high temperature; the application device is used for generating the temperature information of the switching distribution cabinet and warning drive information according to the digital signal; the warning drive information is used for controlling the monitoring device to perform warning on the high temperature. The system has the advantages that external temperature information is converted into the optical information for online testing of the temperature of the switching distribution cabinet, accurate temperature data are acquired, temperature monitoring interval is shortened, temperature measuring is more timely, and burnout of the switching distribution cabinet is avoided.

Description

technical field [0001] The invention relates to the field of power transmission and distribution systems of electric power systems, and more specifically relates to an online monitoring system for the temperature of a switch distribution cabinet. Background technique [0002] With the implementation of the national "Eleventh Five-Year Plan" and the development of the national economy, the society has put forward higher requirements for the reliability of power supply. Very large-scale transmission and distribution and grid security are listed as priority topics within the energy focus area. [0003] In the power system, the safety and reliability of power equipment is an important part of ultra-large-scale power transmission and distribution and grid security. Among them, the power switch distribution cabinet is an important equipment widely used in the power transmission and distribution system, and its safety and reliability are subject to more and more More and more atte...
