【摘要】：本文從寧夏超高壓電網(wǎng)中現(xiàn)役的幾類800kV罐式斷路器入手研究,通過研究其電氣性能、結(jié)構(gòu)特點等參數(shù),結(jié)合近幾年來在寧夏電網(wǎng)的實際運行狀況,對其出現(xiàn)的故障進(jìn)行了追蹤調(diào)研分析,并通過仿真計算對800kV罐式斷路器中絕緣拉桿的電場強度分布,分析絕緣拉桿電場強度分布；通過計算絕緣拉桿的電場分布變化情況,分析在正常溫度下對絕緣拉桿電氣強度的影響程度；通過仿真計算絕緣拉桿有缺陷時的電場強度變化,分析絕緣拉桿的電場分布影響程度。并通過實測該型斷路器絕緣拉桿在操控過程中的應(yīng)變信號,以掌握其實際受力情況,通過絕緣拉桿的應(yīng)力仿真計算為研究其絕緣拉桿缺陷提供試驗數(shù)據(jù)支撐,為800kV罐式斷路器的產(chǎn)品設(shè)計優(yōu)化和安全運行提供理論依據(jù),為后續(xù)新投800kV罐式斷路器設(shè)備安全運行起到借鑒作用。
[Abstract]:This paper starts with the research of some kinds of 800 kV tank circuit breakers in Ningxia UHV power network, through the study of its electrical performance, structural characteristics and other parameters, combined with the actual operation situation in Ningxia power grid in recent years. The electric field intensity distribution of the insulated rod in 800 kV tank circuit breaker is analyzed by simulation, and the electric field distribution of the insulated rod is calculated by calculating the electric field distribution of the insulated rod. The influence of normal temperature on the electrical strength of insulating pull rod is analyzed, and the change of electric field intensity is calculated by simulation. The influence degree of the electric field distribution of the insulated pull rod is analyzed, and the strain signal of the insulation pull rod of the circuit breaker is measured in order to grasp the actual force situation. Through the stress simulation calculation of the insulated pull rod, the experimental data support is provided for the study of the insulation pull rod defect, and the theoretical basis for the optimization of product design and safe operation of 800 kV tank circuit breaker is provided. It can be used for reference for the safe operation of the new 800 kV tank circuit breaker equipment.
