Методи і засоби контролю стану ізоляції та струму витоку тролейбуса

Abstract

The dissertation is devoted to the issue of monitoring the insulation and leakage current trolley in order to increase the reliability of insulation control trolley and trolley control leakage current due to improved methods and means of determination of the basic insulation of electrical components and leakage current. Improved method for determining the ohmic resistance of insulation, which minimizes the impact on the capacitive component measurement application which allows to increase the measurement accuracy of insulation resistance ohmic trolley. Mathematical model of capacitive insulation resistance of the trolley, which allows to determine the capacitive component of the insulation resistance in real time, not vidmykayuchy trolley from the network adapter that allows to increase the reliability of monitoring the insulation resistance of the trolley. The method of adjusting the parameters of isolation, which adjusts the value of insulation resistance of the trolley and contact network for the next period of operation, taking into account the worst weather conditions and the importance of isolation with regard to actual weather conditions, thus improving the level of electrical and uptime trolley. Improved method for monitoring leakage current, which allows you to locate the place insulation damage and identify the fault isolation traction engine
