高压电动机定子绕组绝缘薄弱点的有效定位
High voltage motor stator winding insulation vulnerabilities of effective positioning
摘要
Abstract
For partial discharge detection method (no matter online or off-line),it can only be used to determine the discharge capacity of a phase stator winding insulation,which can be used to detect the discharge position and intensity.According to the situation of the field,the noise,electromagnetic in-terference and other interference sources to the motor stator winding test were reduced,the high voltage motor stator winding sound power of the test of the normal situation and internal discharge.were summed up.A large number of field tests were carried out to establish the discharge points of different types and different discharge levels,and to carry out the accuracy of the spectrum information and to verify the location.The combined detection of the sound and the pulse current is used in combination with the pulse current detection,and the different discharge points of the stator winding of high voltage motor are judged by comparing the signal spectrum and the pulse current detection.The insulation con-dition and performance of the main motor windings of the Jiangdu Railway Station are provided by the positioning test of the weak point of the stator winding insulation of high voltage motor.关键词
