扼要介绍了6kV电网消弧线圈补偿技术和高压选择性接地技术发展及应用现状,在阐述消弧线圈补偿原理、电网单相接地后电容电流分布规律和特点后,剖析了消弧线圈补偿对高压选择性接地保护装置影响的内在原因。
This paper has a brief introduction on the development and application status of the copmpensation technology of arc extinction coil in coal mine 6 kV network and the protection technology of high voltage selective grounding.This paper has pointed out the uncomplement problem in the application.After introductions on the compensation principle of the arc extinction coil,capacitance current distribution law and features after the network single phase grounded,this paper analyzed the inner cause of the arc extinction coil affected to the high voltage selective grounding protection devices which are commonly used.With the applications of the compensation technology of the are extinction coil and the high voltage selective grounding protection technology,this paper also has made some proposals to the organizations who are using the arc extinction coil compensation network for references in order to have a selective grounding protection system from a surface substation to a high voltage gearbox in underground mining section.
