Abstract

The invention discloses an electrode device for measuring the electrical strength of a composite insulator silicon rubber umbrella skirt and a measuring method.The electrode device is characterized by comprising an upper plate, an upper electrode fixed with the upper plate through a bolt, a middle support plate, a lower plate and a lower electrode fixed with the lower plate through a bolt, and the vertical height of the middle support plate and the vertical height of the upper plate are adjustable.In the use process, the height of the upper surface of the middle support plate is adjusted to be flush with the upper end of the lower electrode, a silicon rubber sample wafer is put on the middle support plate, and then the position of the upper electrode is adjusted according to the thickness of the silicon rubber sample wafer to enable the electrodes to directly make tight contact with the sample wafer.In the measuring process, the measuring device is immersed in a container filled with transformer oil, a breakdown voltage value of the silicon rubber sample wafer is measured through a voltage measuring instrument, and therefore the electrical strength of the silicon rubber umbrella skirt is obtained.The electrode device is simple in structure, convenient to install, easy to maintain, convenient and rapid in use method and capable of accurately measuring the electrical strength of the composite insulator silicon rubber umbrella skirt.

Description

technical field [0001] The invention relates to a measuring device and a measuring method for the electric strength of a composite insulator silicone rubber shed. Background technique [0002] Composite insulators are widely used in power systems due to their advantages of high mechanical strength, good pollution resistance and light weight. The silicone rubber shed is the outer insulation part of the composite insulator, and its function is to make the composite insulator have a sufficiently high external insulation performance against moisture flashover and pollution flashover. An important index used to evaluate the quality and operation status of the composite insulator silicone rubber shed is the electric strength, which directly affects its insulation strength. Due to the particularity of the structure of the composite insulator silicone rubber shed and the characteristics of the silicone rubber material, there are few reports on the measurement device for its electri...
