【摘要】：隨著配電網(wǎng)系統(tǒng)線路特別是電纜線路的增加,系統(tǒng)電容電流急劇增大。為降低弧光接地過電壓發(fā)生概率,減少過電壓對(duì)弱絕緣設(shè)備造成損害,目前江西電網(wǎng)10kV和35kV系統(tǒng)逐漸由不接地方式改為經(jīng)消弧線圈接地方式。但由于供電公司技術(shù)人員對(duì)消弧線圈缺乏了解,同時(shí)缺乏消弧線圈必要的運(yùn)行管理措施,致使部分消弧線圈處于非正常工作狀態(tài)甚至長期退出運(yùn)行,多數(shù)消弧線圈處于無人管控、配置不合理的局面。本文分析了電網(wǎng)實(shí)際運(yùn)行中三種常見的接地方式,指出了消弧線圈的作用與使用范圍,介紹了消弧系統(tǒng)的基本原理。根據(jù)江西電網(wǎng)所應(yīng)用的消弧線圈類型,詳細(xì)介紹了五種類型的消弧線圈。將類型各種消弧線圈的調(diào)節(jié)方式,優(yōu)缺點(diǎn)等分別進(jìn)行了分析比較。結(jié)合江西電網(wǎng)消弧線圈實(shí)際運(yùn)行情況,對(duì)消弧線圈運(yùn)行中暴露出的問題進(jìn)行了詳細(xì)分析,查找原因,并應(yīng)用各種試驗(yàn)對(duì)配電網(wǎng)接地方式、消弧線圈選型及運(yùn)行維護(hù)進(jìn)行深入研究,提出了從設(shè)備選型、安裝、調(diào)試、驗(yàn)收及運(yùn)行維護(hù)方面的解決方案,以解決消弧線圈運(yùn)行中存在的各種問題,為江西電網(wǎng)未來選擇消弧線圈及消弧線圈運(yùn)行維護(hù)方面提供指導(dǎo)意見。
[Abstract]:With the increase of the distribution network system line, especially the cable line, the system capacity current is sharply increased. In order to reduce the occurrence probability of the arc grounding overvoltage and to reduce the damage to the weak insulation equipment, the 10kV and 35kV systems of the Jiangxi power grid are gradually changed from the non-grounding mode to the arc suppression coil grounding mode. However, due to the lack of understanding of the arc suppression coil by the technical personnel of the power supply company, the necessary operation management measures of the arc suppression coil are not required, so that the partial arc suppression coil is in an abnormal working state or even exits the operation for a long time, and a plurality of arc suppression coils are in the situation of no control and unreasonable configuration. In this paper, three common grounding modes in the actual operation of the power grid are analyzed, the action and the use range of the arc suppression coil are pointed out, and the basic principle of the arc-extinguishing system is introduced. According to the arc suppression coil type applied in Jiangxi power grid, five types of arc suppression coil are introduced in detail. The adjustment methods, advantages and disadvantages of various arc suppression coils are analyzed and compared. Combined with the actual operation of the arc suppression coil of Jiangxi power grid, the problems exposed in the operation of the arc suppression coil are analyzed in detail, the reason is found, and various tests are applied to the grounding mode of the distribution network, the selection of the arc suppression coil and the operation and maintenance. The selection and installation of the equipment are put forward. The solution in the aspects of commissioning, acceptance and operation maintenance is to solve the problems existing in the operation of the arc suppression coil, and provide guidance for the future selection of the arc suppression coil and the arc suppression coil operation and maintenance of the Jiangxi power grid.
