Abstract
Description
技术领域 technical field
本发明涉及电网领域，特别涉及一种线路绝缘子。 The invention relates to the field of power grids, in particular to a line insulator.
背景技术 Background technique
在中高压或低压线路架设工程中，每一根直线杆上都需要用线路绝缘子来使导线与导线之间或导线与电杆、横担之间绝缘，防止导线漏电的作用。 In the erection project of medium and high voltage or low voltage lines, line insulators are required on each straight pole to insulate the wires or between the wires and the poles and cross arms to prevent the leakage of the wires.
现有技术中长采用陶瓷材料的柱式绝缘子或针式绝缘子，柱式绝缘子或针式绝缘子安装时，需要用到扎线绑扎。柱式绝缘子或针式绝缘子在恶劣气候（雷电、严寒、暴风雨）条件下易断裂损坏，而且扎线容易松动，造成导线从绝缘子上脱离，导致相间短路和单相接地等事故或故障。 In the prior art, post insulators or pin insulators made of ceramic materials are used. When the post insulators or pin insulators are installed, binding wires are required. Post insulators or pin insulators are easily broken and damaged under severe weather conditions (lightning, severe cold, and storm), and the binding wires are easy to loosen, causing the wires to detach from the insulators, resulting in accidents or failures such as phase-to-phase short circuits and single-phase grounding.
