The invention discloses a high-voltage electrified body temperature monitoring system based on a wireless transmission mode, belonging to the field of remote monitoring system. The high-voltage electrified body temperature monitoring system comprises a monitoring center, a transport network and a site plant; a monitoring device is directly installed on the monitoring point of detected high-voltage equipment and is equipotential to the detected equipment; the monitoring device and a data concentrator are communicated in the wireless mode, and the data concentrator is connected with the monitoring center via a wired transport network / GPRS; the monitoring device adopts the design of lower energy consumption, and standby current is smaller than 2 mu A; batteries are adopted to supply power to the monitoring device; and the monitoring device adopts a wireless mode to send data, thus thoroughly solving the problem of high-voltage insulation, and realizing on-line monitoring of the high voltage equipment. The high-voltage electrified body temperature monitoring system gives an alarm in various modes, can find temperature rise of the high voltage equipment in time so as to take measures immediately, thus avoiding accidents and greatly improving the safety of power grid operation.

Description

technical field [0001] The invention relates to a high-voltage electrified body temperature monitoring system based on a wireless transmission mode, which belongs to the field of remote monitoring systems. Background technique [0002] The power system is developing rapidly towards the direction of large power grid with high reliability and high automation level. The level of automation and intelligent monitoring of power grid operation has become a key issue that is highly valued at home and abroad. With the increasing power consumption, the power load of high-voltage electrical equipment such as transformers, high-voltage switchgear, and knife switches, which carry large power transmission tasks, is also increasing rapidly. Many high-voltage electrical equipment in the power grid itself and the connection point between the equipment are the weakest link in power transmission. The real problem of this weak link is the heating of the connection point. As the load increases...

Problems solved by technology

The temperature rise of the switchgear exceeds the standard, which directly affects the safe and stable operation of the equipment. Moreover, the problem of overheating is a continuous development process. If it is not controlled, the degree of overheating will continue to increase, and it will have a great impact on the performance of the insulating parts and the life of the equipment. influences

The temperature-showing wax sheet is obviously behind, and the method of point-by-point temperature measurement with an infrared thermometer has a large measurement error and requires a lot of manpower and material resources

However, this method can only perform periodic inspections, and the cycle is long. The probability of failure due to missed inspections is very high, and there are still many blind spots, which bring hidden dangers to the operation of the power grid.

At present, the position of the circuit breaker, knife switch, dynamic and static contact and other equipment inside the updated handcart switch cabinet is hidden, and the infrared thermometer can no longer carry out manual inspection and temperature measurement.
