Description

Technical Field

[0001] The invention relates to the technical field of insulators, and in particular to a triangular fixed post insulator. Background Art

[0002] Conventional overhead conductor lines are laid through two pillar insulators or suspension insulators, which are fixed on double cross arms and double top sleeves respectively. In particular, the slope difference of pillar insulators is large in mountainous and hilly areas. Due to the action of strong force, the pillar insulator fixing bolts or fixed cross arms and double top sleeves often bend and deform along the direction of the force due to the influence of force, the opening of the cross arms and double top sleeves becomes larger, the cross arms and double top sleeves are twisted and deformed, and the internal structure of the conductor is damaged by excessive conductor tension. In severe cases, the insulator may even be damaged, causing the line to lose insulation protection and directly contact the conductor such as the cross arm, causing the conductor to discharge to the ground. In mild cases, power outages may occur, affecting the normal power use of users. In severe cases, wildfires may be caused, causing immeasurable economic losses and threatening the lives and property safety of the general public. In addition, once the conductor loses the restraint of the supporting point, it is more likely to cause a flying situation, resulting in excessive conductor sag and tension relaxation. Under the influence of a certain wind force, the conductor after flying will have an instantaneous short circuit fault between the phases of the conductor, causing a short circuit fault and power outage. Especially in the windy seasons of spring and autumn, the lines after the flyover will swing with different arcs according to the size of the wind, causing power outages at any time, reducing the reliability of power supply, seriously affecting the normal power consumption of users, and greatly affecting the image and reputation of the company. In view of the above problems, the column insulators with slope differences in the hilly and mountainous areas where overhead wires shuttle through are developed to effectively solve the problem of overhead wires not being deformed and damaged by column insulators under reverse tension. The solution is developed to effectively improve the reliability of power supply and the satisfaction of electricity users in all aspects, and reduce the occurrence of accidents.
