Wiring method for realizing direct-current deicing of ground wire of converter station

Abstract

本发明公开了一种实现换流站地线直流融冰的接线方法,涉及电网输电线路直流融冰技术,旨在是提供一种能有效降低待融冰地线等效电阻的方法。本发明技术要点:包括将需融冰地线进行全绝缘改造的步骤,将全绝缘改造后的地线至多保留一个接地点;将地线分为n段,每条地线段中包含1条地线或1条以上相互平行且两端对齐的地线;将属于同一地线段所有地线的其中一端短接在一起作为该地线段的一端,将属于同一地线组所有地线的另一端短接在一起作为该地线段另一端的步骤;将所有地线段的一端接到导线一上,将所有地线段另一端接到导线二上的步骤;将直流融冰装置输出接入点一与导线一连接的步骤;将直流融冰装置输出接入点二与导线二连接的步骤等。
The invention discloses a wiring method for realizing the direct-current deicing of a ground wire of a converter station, relates to a direct-current deicing technique of a power grid transmission line, and aims at providing a method for effectively reducing the equivalent resistance of the ground wire to be deiced. The technical points of the wiring method are as follows: the wiring method comprises a step of carrying out all-insulation transformation on the ground wire to be deiced, and retaining one grounding point at most after the all-insulation transformation; a step of dividing the ground wire into n sections, wherein each section of the ground wire comprises one ground wire or at least ground wires which are parallel to each other and two ends of which are aligned; a step of connecting one ends of all ground wires belonging to one same ground wire section by means of short circuits so as to be used as one end of the ground wire section, and connecting the other ends of all ground wires belonging to one same ground wire section by means of circuit boards so as to be used as the other end of the ground wire section; a step of connecting one ends of all the ground wire sections with a lead I and connecting the other ends of all the ground wire sections with a lead II; a step of connecting an output access point of a direct-current deicing device with the lead I; a step of connecting the output access point of the direct-current deicing device with the lead II, etc.
