Real-time monitoring system of outdoor electric device

Abstract

The invention discloses a real-time monitoring system of an outdoor electric device. The real-time monitoring system comprises N groups of mutually-independent on-site monitoring devices, a secondary wireless inspection station connected with the N groups of monitoring devices and a ground center inspection station connected with the secondary wireless inspection station. All the on-site monitoring devices are mutually independent and any two groups of the on-site monitoring devices are mutually parallel. Each of the on-site monitoring devices comprises an ultraviolet detector monitor, a humidity and temperature detector and a peak value measuring circuit. The signal output ends of the ultraviolet detector monitors, the signal output ends of the humidity and temperature detectors and signal output ends of the peak value measuring circuits are connected to a signal processing circuit. According to the invention, by means of multi-circuit divided-point, region wireless concentration and bus monitoring control, digital management and monitoring for electric operation device are achieved, and an information monitoring framework cooperating with the star-type or topological type framework is transmitted via the Zigbee network, so highly-efficient and safe operation of electric devices in urban areas can be ensured.

Description

technical field [0001] The invention relates to the field of electric power detection and maintenance, in particular to a real-time monitoring system for outdoor power equipment. Background technique [0002] With the development of society, in order to make it more convenient for residents to use electricity at ordinary times, the current communities are basically equipped with relevant power transformation equipment, and high-voltage power equipment may have partial discharge faults, and partial discharge will have some impact on the insulating medium. Slight partial discharge has little effect on the insulation of power equipment, and the insulation strength decreases slowly, while strong partial discharge will have a serious impact on the insulation of power equipment, which may eventually lead to damage to power equipment, so regular inspection is required For equipment detection and diagnosis, at present, the staff usually come to check and maintain the power equipment...

[0002] With the development of society, in order to make it more convenient for residents to use electricity at ordinary times, the current communities are basically equipped with relevant power transformation equipment, and high-voltage power equipment may have partial discharge faults, and partial discharge will have some impact on the insulating medium. Slight partial discharge has little effect on the insulation of power equipment, and the insulation strength decreases slowly, while strong partial discharge will have a serious impact on the insulation of power equipment, which may eventually lead to damage to power equipment, so regular inspection is required For equipment detection and diagnosis, at present, the staff usually come to check and maintain the power equipment on a regular basis, but this often causes unnecessary waste of personnel resources

[0003] Some important power transfer equipment needs to withstand the load of electricity, heat and machinery, as well as the influence of the natural environment. The long-term operation of the equipment is easy to cause aging and wear, so that the performance of the power equipment will gradually decline, and the reliability of the equipment will also decrease. The failure rate of power equipment will be greatly increased when it goes downhill, which may endanger the safe operation of the power system in the future. Therefore, it is necessary to monitor the status of these devices, especially in urban areas where the population and power operation are concentrated. The operation monitoring of power facilities is particularly important. important
