Adjustable three-phase dry-type transformer binding post

Abstract

The invention relates to the technical field of transformers, and discloses an adjustable three-phase dry-type transformer binding post. The binding post comprises a first porcelain bottle, a circularthrough hole is formed on the top surface of the first porcelain bottle and is positioned in the center of the first porcelain bottle, and two bearings are fixedly installed at the top end and the bottom end of the circular through hole and in an inner cavity of the circular through hole; a second porcelain bottle is arranged below the first porcelain bottle, a threaded rod is arranged at the topof the first porcelain bottle, and the bottom end of the threaded rod penetrates through the inner cavities of the two bearings and extends downwards. According to the adjustable three-phase dry-typetransformer binding post, by rotating the first porcelain bottle, a binding post body has an angle adjusting effect, meanwhile, the clamping device is fixedly installed at the bottom end of the firstporcelain bottle, and a pull rod on the clamping device is in snap joint with a positioning hole on the top face of the second porcelain bottle, so that the first porcelain bottle has the effect of being convenient to fix. The porcelain bottle on the binding post has the angle adjusting function, so that the wire installation speed can be increased.

Description

technical field [0001] The invention relates to the technical field of transformer terminal, in particular to an adjustable three-phase dry-type transformer terminal. Background technique [0002] Three-phase dry-type transformers are widely used in electronic computers, precision machine tools, computer tomography, precision instruments, experimental devices, elevators in industrial and mining enterprises, post and telecommunications, textiles, railways, construction sites, schools, hospitals, hotels, national defense, scientific research and other departments , AC regulated power supply for imported equipment and production lines. At the same time, it is also suitable for low-voltage power distribution with low power supply voltage and large fluctuation range. [0003] At present, the terminal used for three-phase dry-type transformers is only connected to a conductive threaded rod through a porcelain bottle, and a terminal is fixedly installed on the top of the conductiv...
