Embodiment Construction
[0016] In order to enable those skilled in the art to better understand the present invention, the present invention will be further clearly and completely described below in conjunction with the accompanying drawings.
[0017] Such as figure 1 As shown, the present invention provides a clamp for power transformation equipment, including a main pipe 1 and a secondary pipe 2 .
[0018] Such as figure 2 , 3 As shown in and 4, the main pipe 1 includes a main pipe cone 3, the upper part of the main pipe cone 3 is a 2° cone, and the lower part is a section of cylinder. A through hole is opened in the inside of the main pipe cone 3 along the axial direction, and the bus down conductor 11 passes through the through hole. An annular deformation groove 4 is provided on the outer wall of the lower part of the main pipe cone 3, and an external thread 5 is provided on the outer wall of the main pipe cone 3 cylinder at the lower part of the deformation groove 4, and four expansion join...

The invention relates to a wire clamp for a power transformation device. The wire clamp for the power transformation device is convenient to connect and reliable and comprises a main pipe and an auxiliary pipe. The main pipe comprises a main pipe cone body. A through hole is formed in the main pipe cone body in the axial direction, an annular deformation groove is formed in the outer wall of the lower portion of the main pipe cone body, outer threads are arranged on the outer wall of the portion, on the lower portion of the deformation groove, of the main pipe cone body, and four expansion joints are symmetrically formed in the outer wall of the main pipe cone body in the axial direction; an auxiliary pipe cone body cavity corresponding to the main pipe cone body is formed in the auxiliary pipe in the axial direction and inner threads are arranged on the inner cavity wall of the bottom of the auxiliary pipe; the bottom end of the main pipe is connected with a main pipe connecting board, and a bolt hole is formed in the main pipe connecting board. The wire clamp is simple in structure, convenient to carry, easy to implement, convenient to connect and replace, reliable in use, high in universality and suitable for bus down leads of different standards and electrical device terminals of different angles.
Description
technical field [0001] The invention relates to a wire clip for power transformation equipment, in particular to the connection between a bus down-lead and an outlet terminal of an electrical equipment. Background technique [0002] At present, the outlet terminal connection methods used for substation bus down conductors and electrical equipment, such as transformers, short circuit breakers, transformers, isolating switches, wall bushings, etc., are mainly explosive clamps, hydraulic clamps and bolt-type clamps. Wait. With the advancement of technology, explosive clamps and bolt clamps are gradually being replaced by hydraulic clamps. Whether it is an explosive clamp or a hydraulic clamp, there are defects such as difficult construction, many safety hazards, non-reusability, and the damage of the clamp must be replaced together with the busbar down-conductor. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a c...
