Problems solved by technology

At present, multiple probes (generally no less than 10) are used to connect the DC ion current density with communication cables. Due to the large number of probes, it is inconvenient to connect the wires. As the voltage level of the DC line increases, the distance between the pole wires increases. The width of the area to be measured is greatly increased. For example, when the environmental protection acceptance of ±800kV Xiangjiaba to Shanghai DC is required to monitor the cro

Abstract

The invention provides a multi-channel direct current ion current density test device using wireless communication. The device comprises at least 10 microammeters, one upper computer, one PC terminal and Wilson plates which carry out one to one correspondence connection with the microammeters. The device can satisfy a need of long-time field test work. Each microammeter establishes wireless communication with the upper computer through a wireless communication module. The upper computer is connected to the PC terminal through a USB cable. By using the direct current ion current density test device of the invention, sizes and polarities of direct current ion current density of a plurality of points can be conveniently, effectively, accurately and simultaneously measured. Scientific data is provided for direct current power transmission engineering environment electromagnetic environment monitoring, research and evaluation.

Description

technical field [0001] The invention relates to a test device, in particular to a multi-channel DC ion current density test device using wireless communication. Background technique [0002] In recent years, the construction of DC transmission lines in my country has developed rapidly, and the electromagnetic environment around DC transmission lines has attracted more and more attention. Ion current density is the main electromagnetic environment parameter of DC transmission lines and converter stations. With the in-depth development of the environmental impact assessment work of DC transmission projects and the continuous enhancement of people's awareness of environmental protection, the monitoring of DC ion current density has become an important task. important work. [0003] Different from the symmetry on both sides of the AC electric field and the magnetic field and the small change due to the external environment, the DC ion current density is significantly changed by...
