High-voltage lead fixing apparatus of transformer

Abstract

The invention relates to a high-voltage lead fixing apparatus of a transformer. The high-voltage lead fixing apparatus comprises a bottom plate and one or more wire clamps; the high-voltage lead fixing apparatus is characterized in that mounting holes are formed in the two ends of the bottom plate; a circular disk-shaped mounting platform is arranged between the mounting holes in the two sides; a plurality groups of fixing holes I are formed in each mounting platform, and the fixing holes are symmetrically formed in the mounting platform by taking the center of the mounting platform as the symmetrical points; each wire clamp comprises a wire clamp cylinder and fixed lugs; the wire clamp cylinder is cylindrical-shaped, and comprises a wire clamp cylinder A and a wire clamp cylinder B; the wire clamp cylinder A and the wire clamp cylinder B are symmetrical semicircular cylindrical-shaped, and one ends thereof are hinged while the other ends form an opening of the wire clamp cylinder in a surrounding manner; the fixed lugs are arranged on the wire clamp cylinder A and the wire clamp cylinder B in the outer wall tangential direction of the cylinders; and fixing holes II are formed in the fixed lugs. According to the high-voltage lead fixing apparatus of the transformer, the multi-angle mounting of the high-voltage lead of the transformer can be realized through the wire clamp which can be fixed on the bottom plate in a multi-angle manner.

Description

technical field [0001] The invention relates to a fixing device, in particular to a fixing device for high-voltage lead wires of a transformer. Background technique [0002] Transformer is an important equipment in the power system, which plays the role of electric energy conversion and transmission, and is of great significance in the economical transmission, flexible distribution and safe use of electric energy. With the acceleration of urbanization, the long-term safe operation of transformers is becoming more and more important. Among them, the structure of transformer leads is one of the main factors affecting the safe operation of transformers. The lead wire of the transformer refers to the wire connected to each lead-out end of the winding outside the transformer. The transformer inputs the external power supply power into the transformer through the lead wire, and at the same time transmits the transmitted electric energy from the transformer to the outside through t...

AI Technical Summary

Problems solved by technology

The transformer high-voltage lead wire is usually fixed by two pieces of electrical wood, one of which is slotted according to the size and size of the lead wire, and the other is not slotted. The two pieces of electrical wood clamp the lead wire through bolts, nuts and washer clips. The disadvantage of the method is that the assembly is complicated and the work efficiency is reduced. If the electrical wood clamp is too long, the center needs to be fixed with bakelite bolts and nuts; on the other hand, the high-voltage leads are drawn from various mechanical parts inside the transformer box. When the wooden clips are uniformly arranged, all the lead wires are arranged together, which will cause the bending angle of some lead wires to be too large, resulting in damage to the lead wires and affecting the normal operation of the transformer.
