Abstract

The invention discloses a simulation test device for bundled conductor corona discharge in a laboratory. The conventional corona discharge simulation test device used in a laboratory or a research institution has the defects that the test device cannot simulate various atmosphere environment parameters such as humidity and air pressure through manual control, and the simulation test and research on bundled conductors cannot be realized through adopting a single conductor model to research the single conductor corona discharge. The simulation test device provided by the invention is characterized by comprising a cylindrical corona and shield cage, an atmosphere environment parameter simulator, a simulation conductor adjusting and fixing device and a corona measuring device, wherein the corona measuring device is mounted on the cylindrical corona and shield cage. The simulation test device can simulate various atmosphere environment parameters such as humidity and air pressure, is suitable for bundled conductor with various bundle spacings and models, and meets the requirements of a simulation test for bundled conductor corona discharge in the laboratory under complex atmosphere environmental conditions; besides, the adjustability of testing conditions is higher.

Description

technical field [0001] The invention relates to the field of split wire corona, in particular to a split wire corona discharge laboratory simulation test device. Background technique [0002] The corona discharge generated by the transmission line will cause corona energy loss, radio interference, etc. EUHV transmission lines mostly use split conductors, and the corona discharge of split conductors and the electromagnetic problems caused by them are major technical issues that must be considered in line design and operation. Generally, corona discharge test devices are divided into two categories, one is large-scale outdoor test devices, and the other is small-scale test devices for laboratories; among them, corona discharge laboratory simulation test devices have small investment and high test conditions. Controllable, short test cycle and other advantages. [0003] However, the corona discharge laboratory simulation test device currently used also has some shortcomings: ...
