Problems solved by technology
However, due to the large differences between the system structure and operation and maintenance methods of the underground layout technology and the existing methods, it is difficult to directly apply the existing various equipment detection methods and systems; at the same time, the operation stability and life of the system are improved due to the underground operation of the secondary equipment , the operation and maintenance work usually reduces the number of on-site operations and the regular inspection cycle of the equipment, and it is more necessary to realize the remote online monitoring of the equipment

The invention relates to the technical field of substation in-situ secondary equipment operation environment monitoring, in particular to an underground operation environment monitoring and evaluationsystem and method for in-situ protection device. The evaluation system is composed of a sensing system, a communication system and a monitoring system. The monitoring system is connected with the sensing system through the communication system; the sensing system collects information of a plurality of devices and setting positions and transmits the information to the monitoring system through thecommunication system, and the monitoring system compares, analyzes and processes the received collected information. The evaluation method comprises the following steps: firstly, the sensing system is mounted on different devices and setting positions, and the monitoring system is connected through the communication system; the sensing system collects information of a plurality of devices and setting positions and transmits the information to the monitoring system through the communication system; and finally, the monitoring system performs comparative analysis and processing on the receivedacquired information. According to the invention, multi-point long-term online monitoring of the underground operation space of the equipment is realized, and the requirements of the underground operation and maintenance mode of the equipment are effectively ensured.
Description
technical field [0001] The invention relates to the technical field of substation in-situ secondary equipment operation environment monitoring, in particular to an in-situ protection device underground operation environment monitoring and evaluation system and method. Background technique [0002] The local layout of secondary equipment is one of the development directions of power secondary system technology in recent years. Since the equipment faces a variety of harsh outdoor operating environments after localization, which has a serious impact on the reliability and life of the electronic equipment, the existing various secondary equipment localization schemes are in the use of additional protective facilities or the protective performance of the equipment itself. While improving, a monitoring system for the operating environment of the equipment or the operating status of the equipment itself is also set up to monitor and evaluate the real-time operating status of the lo...
