Abstract

The invention relates to a long-term continuous monitoring trolley for an electromagnetic environment of an ultra-high voltage AC and DC parallel transmission line. The trolley can reciprocate on a track and automatically monitor the parallel transmission line, and manpower is saved. A DC composite field strength meter and a power frequency electric field environment monitor are set on an exposedflat panel. A radio interference monitor, an industrial control machine which is used for receiving the data of the DC composite field strength meter, the power frequency electric field environmentalmonitor, the radio interference monitor and a noise meter, and a power module for supplying power to the industrial control machine and a motor are set in a metal box, and the minimum distance of theDC composite field strength meter and the power frequency electric field environment monitor from the metal box is larger than 3 meters, the electromagnetic interference between instruments is avoided, and the measurement accuracy is improved.

Description

technical field [0001] The invention belongs to the technical field of electromagnetic environment monitoring of transmission lines, and in particular relates to a trolley for long-term continuous monitoring of the electromagnetic environment of UHV AC / DC parallel transmission lines. Background technique [0002] my country is leading the construction of the global energy Internet, and the construction of UHV power grids ushers in a new high-speed development opportunity. With the continuous construction of UHV transmission lines in my country, the implementation of projects such as national grid connection of power systems, north-south interconnection, and west-to-east power transmission, the AC-DC parallel transmission pattern of my country's power grid has basically formed. With the rapid economic development in various places, transmission corridors are increasingly in short supply, especially in economically developed areas. Parallel erection of AC and DC lines has beco...
