Embodiment Construction

[0021] In order to satisfy all types of suspension insulators, the size of the design device is based on the measurement of the creepage distance of the largest suspension insulator. Currently the largest suspension insulator has a nominal diameter of 500mm and a nominal height of 200mm.

[0022] The frame is welded from a 30mm×30mm×3mm square tube, and its approximate size is 1200mm long, 400mm wide and 1200mm high.

[0023] The sliding guide rail is a commonly used guide rail in the market, and there are many choices. This device adopts the obang era Chaoqun 42 stepping motor ball screw with line rail guide rail slide table. The total length is 400mm.

[0024] The laser rangefinder can choose a laser rangefinder module with high precision, and the USB method is the best, which is easy to transfer to the computer for operation.

[0025] The tension sensor is used to monitor the tension of the suspension insulator, so as to protect the electric push rod and avoid the large s...

Description

technical field [0001] This measuring device is mainly used in the measurement of some parameters of suspension insulators, that is, to measure parameters such as disk diameter, axial deviation, radial deviation, overall height and creepage distance of suspension insulators. These parameters will affect suspension insulators. Electrical characteristics of insulators and their installation issues. Background technique [0002] When selecting the type and quantity of suspension insulators, some parameters will always be used as standards. The parameters of the disk diameter, axial deviation and radial deviation of the suspension insulator affect the installation size of the suspension insulator, and its creepage distance will affect its electrical characteristics. However, due to the limitation of production conditions, the suspension insulators produced are mostly irregular, which requires testing of these suspension insulators to see if they are qualified. At present, ther...
