Embodiment Construction

[0011] In order to make the technical means, creative features, goals and effects achieved by the present invention easy to understand, the present invention will be further described below in conjunction with specific illustrations.

[0012] Such as figure 1 As shown, an on-line monitoring device for the insulation of power grid equipment includes an insulation detector installed at an electrical node. The insulation detector has a built-in wireless transmitting module, and the detected data is sent to the wireless receiving base station wirelessly through a wireless signal. The wireless receiving base station receives the data status of each electrical node, and transmits the received data to the data processor through the Ethernet, and the data processor processes and analyzes the data, and sends the processed data to the single chip microcomputer through the signal amplification circuit , the single-chip microcomputer displays the performance of the insulation node, and gi...

Abstract

The invention provides an online insulation monitoring device of a grid device, and relates to the technical field of electrical. The online insulation monitoring device of the grid comprises an insulation detector that is mounted at an electrical node; a wireless transmission module is arranged in the insulation detector and used for transmitting the detected data to a wireless receiving base station through a wireless signal by a wireless mode; the wireless receiving base station receives the data condition of each electrical node and transmits the received data to a data processor through Ethernet; the data processor processes and analyzes data and conveys the processed data to a single-chip microcomputer through a signal amplifying circuit; the single-chip microcomputer is used for displaying the performances of the insulation node and alarming and reminding for an unqualified insulation node; the positions of the unqualified nodes are sent to a repairer through network and then repairer goes to repair. With the adoption of the online insulation monitoring device of the grid device, manual inspection of the traditional substation is replaced, the workload of maintenance personnel at the substation is decreased, and meanwhile, an operator can monitor the insulation condition of each substation on real time.

Description

technical field [0001] The invention relates to the field of electrical technology, in particular to an on-line monitoring device for grid equipment insulation. Background technique [0002] At present, my country's power system is developing rapidly in the direction of large power grid, high reliability and high automation level. The level of automatic and intelligent monitoring of power grid operation has become a key issue in the development of my country's power system. With the economic development of our country, social power consumption is also increasing day by day, and the power load of high-voltage electrical equipment such as transformers, transformers, switches, high-voltage switchgear, cables, etc., which carry large power transmission tasks, is also increasing rapidly. [0003] The connection points between numerous high-voltage electrical devices in the grid are the weakest link in power transmission. Because during long-term operation, these connection poin...
