Problems solved by technology

However, in UHV transmission lines, the length of composite insulator strings is generally more than 10 meters. It is conceivable that the overall workload of installing a 10-meter-span suspension bridge at high altitude is relatively large and cumbersome, and it is difficult to achieve
Even if it is barely achieved, safety and practicality cannot be guaranteed at all, and the cost is too high
[0006] At present, there is a lack of an outlet device that can help the staff complete the outlet process without damaging the composite insulator string

Embodiment Construction

[0041] The following is attached Figure 1-9 The features and principles of the present invention are described in detail, and the examples given are only used to explain the present invention, not to limit the protection scope of the present invention.

[0042] like figure 1 As shown, the present invention includes a hook assembly 1 , a hanger 2 , a safety belt 4 and a pedal assembly 3 . The bottom of the hanger is fixedly connected with the pedal assembly, and the top is connected with the hook assembly through a movable buckle. The hook assembly 1 is hung on two parallel and adjacent composite insulator strings, and the hook assembly 1 includes several inverted J-shaped hook sleeves 11 and several semi-cylindrical positioning pads 12, each J-shaped The length of the hook cover and the positioning pad 12 is both 1.2m to 1.5m. Generally, only about 8 J-shaped hook sets are needed for an insulator string of about ten meters. The length of the J-shaped hook cover and the posi...

Abstract

A non-continuous suspended anti-sway outlet device includes a hook assembly, a rack safety belt and a pedal assembly. The hook assembly hangs on two parallel and adjacent composite insulator strings. The hook assembly and the pedal assembly are connected through a rack, and the pedal assembly is located below the hook assembly. An anti-sway rod is disposed on the hook assembly. Further disclosed is an installation method of the device. A J-shaped hook sleeve and a rubber positioning pad hang on the insulator strings, and the positioning pad wraps the top of the insulators inside, so that the insulators are effectively protected.

Description

technical field [0001] The invention relates to the technical field of power transmission lines, in particular to a non-continuous suspension type anti-sway outlet device and an installation method thereof. Background technique [0002] In recent years, with the increasing demand for electricity and the development of transmission technology, UHV transmission lines such as 800kV and 1000kV have begun to be constructed and put into use in China. In areas with heavy pollution levels, the use of composite insulators to improve the ability of transmission lines to withstand pollution flashover can play a positive role in preventing and containing the occurrence of pollution flashover accidents, and composite insulators have the advantages of low cost and maintenance-free. Promotion and application, the effect is remarkable. [0003] Conventional tension insulator strings generally use glass insulators or porcelain insulators. When operating, the staff need to step on and climb ...
