Description
Technical Field
The utility model relates to the technical field of electricity, in particular to the technical field of tubular bus installation.
Background
An existing MGG-type pipe bus bar fixing fitting chassis is provided with a mounting hole, as shown in fig. 1. The mounting holes are arranged in a circle, and the chassis is fixed on the insulator by bolts during mounting. According to the current national standard GB/T8287.2-2008 nominal voltage is higher than 1000V system indoor and outdoor post insulator part 2: dimension and characteristic, the upper accessories of all models of insulators are provided with central holes, and only the upper accessories of partial models of insulators are provided with auxiliary holes. Therefore, when the existing MGG type pipe bus fixing fitting is adopted, the selection of the matched insulator is limited or wasted, and sometimes even the field size limitation causes great difficulty in installation work.
Disclosure of Invention
In order to make up the defects of the prior art, the utility model provides a tubular bus fixing hardware fitting suitable for mounting an insulator or a high-voltage live display sensor.
The utility model adopts the following technical scheme:
a tubular bus fixing hardware fitting is used for fixing a tubular bus on an insulator or a high-voltage live display sensor. Comprises a base and an upper cover. The base of the hardware fitting is connected with the upper insulator accessory through a bolt, the upper cover of the hardware fitting is connected with the base through a bolt, a circular cavity is formed between the upper cover of the hardware fitting and the base, and the cavity is used for allowing a tubular bus to pass through.
Round holes with different diameters are formed in the center of the base of the hardware fitting, and the diameter of the round hole at the lower part is smaller than that of the round hole at the upper part; the two round holes are coaxial and form a step.
The joint surface between the hardware fitting upper cover and the base is positioned in the horizontal middle position of the circular cavity, the joint surface forms mutually matched high and low steps, and gaps are reserved on the steps in the vertical direction.
