Description

Technical Field

[0001] The utility model belongs to the technical field of insulators, and in particular relates to a novel rod-shaped composite porcelain insulator. Background Art

[0002] Rod-shaped suspension composite insulators are instruments composed of umbrella sleeves, core rods and hardware at both ends. Many disc-shaped insulators are hung at one end of the high-type high-voltage wire connection tower. It is used to increase the creepage distance. It is usually made of glass or ceramics, which is called an insulator. Insulators play two basic roles in overhead transmission lines, namely supporting the conductors and preventing the current from returning to the ground. During the operation of high-voltage lines, due to the long-term impact of high-voltage electricity and natural factors such as wind and sun, insulators will age and crack, resulting in reduced dielectric strength of the insulators, or even damage, which threatens the safety of power operation. In order to ensure the safety and reliability of power operation, power workers need to regularly inspect and replace insulators. Breaking insulators is one of the inspection methods. During the inspection, if the insulator looks intact on the outside, but is actually damaged or cracked inside, use a hammer to hit the shell of the insulator. If the insulator is seriously damaged inside, the sound will change or break. By breaking the insulator, it can be detected whether there are cracks or damage inside the insulator, and problematic insulators can be discovered and replaced in advance.

[0003] At present, the insulating umbrella cover of the rod-type composite porcelain insulator is made of fragile porcelain and is of special shape. Therefore, the rod-type composite porcelain insulator is easy to move in the transport box during bumpy transportation, and the insulating umbrella cover is easy to be damaged by colliding with the box wall. When personnel use a hammer to knock the insulating umbrella cover close to the insulator for knocking inspection, the insulating umbrella cover will be fragmented and splashed when it is damaged, posing a risk of injury. In addition, knocking at a high place causes the fragments to spread and is not easy to be properly collected. Utility Model Content
