摘要

运行于中压电力系统的电抗器中

干式空心结构的应用比例最大。目前或因电抗器重要性不比主变等设备

对电抗器的事故分析和保护研究并不多。现有保护装置并不能及时准确地针对电抗器故障进行动作

所以干式空心电抗器基本在无保护状态下运行

一旦事故发生

不及时切除故障电抗器

可能会带来更大的次生灾害和损失。为解决此问题

作者探讨干式空心电抗器匝间短路的监测理论

基于Labview软件进行控制算法编写

采用Ansoft软件对电抗器发生匝间短路时的磁场变化进行仿真

并生产保护装置和用于匝间短路测试的电抗器样机1台进行测试。最后结合仿真结果和根据实际可行性

给出了工程上的应用建议。

Abstract

The reactors are running in medium voltage system

it often use dry-type air-core construction.Maybe the reactor is less important than transformers and other devices

at present

there is no many analysis and research on the reactor accident and protection. The existing protection device can not timely and accurately acting for the reactor fault

the existing protection device for reactor failure is not timely and accurately for action

therefore the dry-type air-core reactor is running under the no protection state.Once the accident occurs

the fault reactor has not been removed in time

it may lead to greater secondary disasters and losses. In order to solve this problem

the author studies the monitoring theory of interturn short circuit for dry-type air-core reactor

compiles control algorithm by Labview software

simulates the magnetic field variation when reactor occurs interturn short circuit

develops protection devices and a reactor model machine for testing the interturn short circuit. Finally

according to the simulation result and practical feasibility

the suggestion is given for the application of engineering.
