Quadrifid insulated damping conductor spacer

Abstract

The invention discloses a quadrifid insulated damping conductor spacer matched with a hot-line de-icing scheme of a transmission line, which is realized by frameworks and a line clamp main body, wherein the frameworks are made of glass fiber reinforced plastics, consist of lug boss type positioning stop blocks and are symmetrically arranged close to the inner side outside each connecting hole on the inner side of a rectangular framework, and the line clamp main body consists of a line clamp with a connecting joint. The quadrifid insulated damping conductor spacer not only can reliably separate and support a quadrifid conducting line, but also has good insulating effect so as to ensure that four conducting lines are mutually insulated, thereby creating necessary conditions for the hot-line de-icing of the transmission line, avoiding the harm brought by ice and snow disasters and increasing the bearing strength of the conductor spacer. Because of the improvement on a positioning structure, the line clamp main body and a rubber block, the centripetal force of the conductor spacer can be increased at the same time of simplifying the structure so as to ensure that a damping joint moves along the conducting line all the time and guarantee that the conducting line has damping effect and good positioning when being moved within any possible ranges. The quadrifid insulated damping conductor spacer has simple structure, easy manufacture, reliable performance, low manufacturing cost, economy, practicality and convenient mounting and is suitable for popularization and ice coating areas.

Description

Technical field: [0001] The invention relates to a damping spacer bar which provides high-efficiency vibration damping for overhead power transmission lines and supports and isolates four-split conductors. Background technique: [0002] In the multi-split high-voltage transmission lines of the power system, a split damping spacer is generally installed every 50 or 60 meters to suppress the breeze vibration and sub-gap vibration of the high-voltage wires and ensure the safe operation of the power system. The split damping spacer has two splits, three splits, four splits, six splits, and eight splits, and the four-split damping spacer is the most used one. The four-split damping spacer is made of the four vertices of the rectangle, that is, the four corners. A double frame with a connection hole and an elliptical positioning hole is provided outside the connection hole, and a clamp body with a protruding tail and a cast stainless steel rod is connected through the connection h...
