Infrared intelligent online monitoring system for direct-current convertor station valve hall

Abstract

The invention relates to an infrared intelligent online monitoring system for a direct-current convertor station valve hall. The infrared intelligent online monitoring system comprises a thermal infrared imager, an optical transmitter and receiver, a switch, a background controller, a visible light camera, a micro controller, a cradle head and a controllable track, wherein both the thermal infrared imager and the visible light camera are arranged on the cradle head, and are connected with the micro controller and the optical transmitter and receiver; the cradle head is arranged on the controllable track; the micro controller is connected with the cradle head and the controllable track respectively; the optical transmitter and receiver is connected with the switch; and the switch is connected with the micro controller and the background controller respectively. Compared with the prior art, the infrared intelligent online monitoring system has the advantages that each heating element of a valve body can be subjected to infrared monitoring in real time; meanwhile, an alarm signal is transmitted according to a preset early warning value, and the running safety of equipment is ensured by means of lowering of the load or change of the system running way and the like, so that the equipment running safety is ensured, and the identification capability and foreseeability of running personnel specific to equipment defects are enhanced; and the infrared intelligent online monitoring system has the advantages of simple structure, convenience in installation, high instantaneity and the like.

Description

technical field [0001] The invention relates to a monitoring system, in particular to an infrared intelligent online monitoring system for a valve hall of a DC converter station. Background technique [0002] At present, with the development of UHV and EHV technologies, converter stations occupy an increasingly important position in the power grid. Therefore, it is particularly important to judge whether the valve equipment in the valve hall of the converter station is operating normally. Infrared temperature measurement is the main monitoring method. Since ordinary infrared thermal imaging remote detection is generally manual monitoring, this often causes monitoring delays and causes relatively large property losses. In addition, for some special occasions, such as the thermal state detection of the operating equipment in the valve hall of the converter station or the operating equipment of the unattended substation, if the infrared equipment is manually operated, it will...

Since ordinary infrared thermal imaging remote detection is generally manual monitoring, this often causes monitoring delays and causes relatively large property losses

In addition, for some special occasions, such as the thermal state detection of the operating equipment in the valve hall of the converter station or the operating equipment of the unattended substation, if the infrared equipment is manually operated, it will often cause defects such as increased labor intensity and untimely diagnosis.

In short, although the current infrared thermal imager has been continuously improved in thermal image processing technology, it still needs to be controlled by humans, which still does not reduce the convenience of people's work and the real-time control.
