Triangular fixed post insulator

Abstract

The invention discloses a triangular fixed post insulator, which comprises a bracket main body, a middle block connected with the insulator, a bracket rod rotationally connected with the middle block and a foot block hinged to the lower end of the bracket rod, and the foot block is in threaded connection with a cross arm; the mounting assembly comprises a connecting rod connected to the middle block in a sliding manner and a locking piece arranged on the connecting rod; the adjusting assembly is arranged on the middle block, a traditional single supporting column is changed into double supporting columns, the supporting height of the insulator is reduced, and from the mechanical angle, the higher the height is, the smaller the transverse stress is, an insulator supporting column bolt is reduced to 100 mm, the insulator supporting column bolt is fixedly installed at a bolt hole in the top end of a triangular frame, and bolt connection is designed and used.

Description

technical field [0001] The invention relates to the technical field of insulators, in particular to a triangular fixed post insulator. Background technique [0002] Conventional overhead conductor lines are laid through two pillar insulators or suspension insulators, which are fixedly installed on the double cross arm and double top sleeve respectively. , it often happens that the fixing bolts of the column insulator or the fixed cross arm and double top sleeve will bend and deform with the direction of the force due to the influence of the force, the opening of the cross arm and double top sleeve will become larger, the cross arm and double top sleeve will be twisted and deformed, and the wire tension will If it is too large, it will damage the internal structure of the wire; in severe cases, it will even cause damage to the insulator and cause the line to lose its insulation protection.

[0002] Conventional overhead conductor lines are laid through two pillar insulators or suspension insulators, which are fixedly installed on the double cross arm and double top sleeve respectively. , it often happens that the fixing bolts of the column insulator or the fixed cross arm and double top sleeve will bend and deform with the direction of the force due to the influence of the force, the opening of the cross arm and double top sleeve will become larger, the cross arm and double top sleeve will be twisted and deformed, and the wire tension will If it is too large, it will damage the internal structure of the wire; in severe cases, it will even cause damage to the insulator and cause the line to lose its insulation protection. Direct contact with conductors such as cross-arms will cause the wire to discharge to the ground. Estimated economic losses and accidents that threaten the lives and property safety of the general public; moreover, once the wire loses the shackles of the support point, it is more likely to cause a flying situation, resulting in excessive sag of the wire, loose tension, and Under the influence of a certain wind force on the wire, an instantaneous short-circuit fault will occur between the phases of the wire, resulting in a power outage due to the short-circuit fault of the line

Especially in the windy seasons of spring and autumn, the lines after flying gears will swing in different arcs with the magnitude of the wind force, resulting in power outages at any time, reducing the reliability of power supply, seriously affecting the normal power consumption of users, and greatly affecting the corporate image and reputation
