Abstract

A lightning-proof strain composite insulator comprises a connecting fitting A, a connecting fitting B, tie buckle holes, insulating shields, arc rings, sealing ports, silicone sheds, an insulating mandrel and a silicone rubber sleeve. The outer side of the insulating mandrel is provided with the silicone rubber sleeve. Large and small silicone sheds are successively arranged on the outer side of the silicone rubber sleeve in pairs. The two sides of the insulating mandrel are provided with the sealing ports. The outer sides of the sealing ports at both sides are provided with the arc rings. The outer sides of the arc rings at both sides are provided with connecting fittings A and the connecting fittings B respectively. The outer sides of the connecting fittings A and the connecting fittings B are provided with insulating shields. The same sides of the insulating shields at both ends are provided with the tie buckle holes. The connection fittings A and the connecting fitting B are provided with connecting pin holes. The connecting pin hole on the connecting fitting B is provided with a connecting pin and a camel pin successively. The lightning-proof strain composite insulator is good in performance, reliable, tolerant, stable and reasonable in structure, simple, high in efficiency, long in service life, safe and convenient to use, practical, and effective in updating, and low in operation and maintenance cost.

Description

technical field [0001] The invention belongs to the field of equipment related to high-voltage transmission line engineering, and in particular relates to a lightning-proof and tension-resistant composite insulator. Background technique [0002] At present, the idea of ​​using insulators in our country still stays on the design concept of "composite for straight lines, porcelain and glass for tension strings". The work is more complicated when using porcelain and glass insulators for tension strings, except for adding too many insulator sheets. In addition, it is necessary to adjust the sag of the wire and consider the force of the tower. Therefore, the lack of anti-fouling flashover capability of the tension string has become increasingly apparent. At the same time, the porcelain insulators used in the tension string need to be regularly checked and cleaned, and the maintenance cost is high. [0003] At this stage, the use of composite insulator tension strings on 220kV tra...
