[0003] In order to prevent the above-mentioned accidents, the power department arranges regular inspections every year, and uses infrared thermal imaging cameras, infrared thermometers, etc. to measure the temperature of the equipment joints, and has achieved certain results. Due to the influence of the current of the line, all abnormal temperature rises cannot be found; in addition, in closed spaces such as inside the switch cabinet, it is impossible to use handheld instruments to measure the operating conditions of internal equipment, which has certain limitations

Embodiment Construction
[0013] The present invention will now be further described in conjunction with the accompanying drawings and preferred embodiments. These drawings are all simplified schematic diagrams, which only illustrate the basic structure of the present invention in a schematic manner, so they only show the configurations related to the present invention.
[0014] Such as figure 1 The shown passive wireless high-voltage equipment temperature online monitoring system has a host computer 1, the host computer 1 is connected to the high-voltage equipment temperature centralized monitoring host 2 through the network, the monitoring host 2 is connected to the monitoring device 3, and the monitoring device 3 is connected to the transmission Connector 4;
[0015] The data between the transmitter 4 and the monitoring device 3 is transmitted through sound waves. The transmitter 4 is installed at the detection point of the equipment under test, and can directly use the very weak induction power on...

The invention relates to a passive and wireless high-voltage device temperature online monitoring system which comprises an upper computer which is connected with a high-voltage device temperature centralized monitoring host through a network. The monitoring host is connected with a monitoring device which is connected with a transmitter. The passive and wireless high-voltage device temperature online monitoring system is simple in structure and safe in use, real-time online monitoring can be achieved by directly using a high-voltage device connector, the monitoring can not be influenced by voltage impact and influence of magnitude currents passing through the high-voltage device, even the tail end of a circuit can normally work, operation safety of the high-voltage device is guaranteed, and safety and reliability are achieved.
Description
technical field [0001] The invention relates to a passive wireless high-voltage equipment temperature online monitoring system. Background technique [0002] During long-term operation, due to manufacturing or use reasons (such as Loose, poor contact, etc.), the temperature of the joints often rises abnormally. If it cannot be found and maintained and repaired in time, the joints of the equipment will cause serious equipment accidents due to overheating and melting. Fires and power outages caused by overheated joints are common. [0003] In order to prevent the above-mentioned accidents, the power department arranges regular inspections every year, and uses infrared thermal imaging cameras, infrared thermometers, etc. to measure the temperature of the equipment joints, and has achieved certain results. The line is affected by the magnitude of the current, and all abnormal temperature rises cannot be found; in addition, in closed spaces such as inside the switch cabinet, it...
