Problems solved by technology

[0004] In order to solve the problems of stress concentration and uneven distribution of electric field affecting the measurement accuracy that are easy to occur during the casting process of EVT components, the invention provides an insulator with built-in capacitor EVT components and its processing method. During the casting process of EVT, the upper and lower ends of the EVT increase A pressure equalizing cover is installed to prevent the uneven electric field. In order to prevent the uneven stress of the insulator from affecting the accuracy of the EVT device when the insulator is subjected to external force, a silicon rubber sealing ring is added in the equalizing cover. The threaded inserts of the terminal and the ground terminal are screwed together to realize electrical connection, and a small sealing ring is set in the hole of the pressure equalizing cover to prevent epoxy from entering during casting.

Abstract

The invention relates to an insulator with a built-in capacitor EVT assembly and a processing method thereof, the upper end and the lower end of an EVT are additionally provided with voltage-sharing covers to prevent an electric field from being uneven, and in order to prevent the uneven stress of the insulator under an external force from affecting the precision of an EVT device, silicon rubber sealing rings and voltage-sharing cover openings are additionally arranged in the voltage-sharing covers and screwed together with EVT grounding end inserts. Electric connection is realized, the insulator grounding insert can be welded on the voltage-sharing cover through a vertical lead, and the process is simplified. And a small sealing ring is arranged in a pressure equalizing cover hole to prevent epoxy from entering during casting. And a sealing ring is added at the head of the sunk screw screwed into the high-low pressure insert, so the stress at the high-low pressure insert is relieved.An EVT signal insert is welded with the signal insert in the insulator through the Z-shaped flexible lead, and the flexible lead is easy to install and produce in a mold and is not easily interfered by stress, so that the signal transmission precision is ensured. The insulator with the built-in high-precision EVT assembly cast through the method is high in external force interference resistance and reliable in performance.

Description

technical field [0001] The invention relates to the technical field of on-line monitoring of power equipment status, in particular to an insulator with a built-in capacitor EVT component and a processing method thereof. Background technique [0002] The ubiquitous power Internet of Things is the core task of implementing the national grid's "three-type, two-network, world-class" strategic goal, which requires power transmission and distribution equipment to be able to achieve comprehensive awareness of operating status and full penetration of services. This requires deep integration of primary and secondary equipment, casting high-precision EVT for secondary measurement into traditional primary equipment, and comprehensively monitoring the operation status of primary equipment. [0003] The accuracy of EVT components designed by the principle of capacitive voltage division is restricted by many factors, such as stress concentration and uneven distribution of electric field. ...
