摘要

文中对装置进行分析后认为:固定接入装置存在因线路自动重合闸而产生高的过电压以及运行中可能出现过补偿等隐患;当采用外熔断器或内熔丝作为电容器内部故障保护时

则分别要求每相电容器并联台数不少于4台或电容器内串联段中需有足够数量的并联元件。据此提出了适当增加并联元件数、提高元件的耐电强度以及增设不平衡保护的建议。

Abstract

In this paper

it is thought after the analysis of the device that the fixed access device has such hidden dangers as high overvoltage due to reclosing operation of line and over compensation which is possibly occurs during the operation.In case of adopting external fuse or internal fuse wire as internal fault protection of capacitor

the number of parallel connected capacitors for each phase not less than 4 units and sufficient shunt elements in the series connection section inside the capacitor are required respectively.Based on this reason the suggestions has been put forward that appropriately increase the number of shunt elements

improve withstand voltage strength of elements and add imbalance protection.
