Online monitoring system and online monitoring method of high-voltage insulator filthy state

Abstract

The invention discloses an online monitoring system and an online monitoring method of a high-voltage insulator filthy state. A leakage current collecting unit transmits collected leakage current data to a data sending module. An induction coil transmits an induced current from a high-voltage power transmission line to a power supply module, and the power supply module supplies power sources to the data sending module and the leakage current collecting unit. The data sending module sends data collected by a current sensor to a wireless data concentrator, and the wireless data concentrator transmits collected data to a background server through a global system for mobile communications (GSM) data public network or a general packet radio service (GPRS) data public network. The online monitoring system and the online monitoring method of the high-voltage insulator filthy state have the advantages of supplying stable and reliable electric energy to a signal collection terminal of the online monitoring system of the high-voltage insulator filthy state through a self-induced power supply device, and bringing possibilities for the system to achieve functions of real-time detection, fault diagnosis, early warning and the like of monitoring the high-voltage insulator filthy state.

Description

technical field [0001] The invention relates to an on-line monitoring system and method for the pollution state of high-voltage insulators, which can be applied to real-time and on-line monitoring of the pollution state of insulators in high-voltage transmission lines of substations or power plants. Background technique [0002] With the rapid development of the national economy, the demand for electricity in various industries is increasing. There are many power transmission lines all over the country and they are scattered geographically. Stable operation. [0003] With the demand for national smart grid construction and the development and application of technology, the importance of high-voltage line pollution status monitoring systems has become increasingly apparent. Because most of the transmission lines are located in remote locations, it is difficult to solve the power supply problem by conventional methods. Due to the limitation of energy conversion rate, climate ...

[0003] With the demand for national smart grid construction and the development and application of technology, the importance of the monitoring system for the pollution status of high-voltage lines has become increasingly apparent. Because most of the transmission lines are located in remote locations, it is difficult to solve the power supply problem by conventional methods

Due to the limitation of energy conversion rate, climate environment and cost, solar power supply cannot fully meet the requirements of equipment for all-weather and long-term stable energy supply; while the battery life is low and maintenance costs are high, which makes it difficult to popularize on high-voltage transmission lines Realize online real-time monitoring function
