Pressing device of integral shunt reactor body

Abstract

The invention relates to a pressing device of an integral shunt reactor body, being especially suitable for a shunt reactor with a pull rod-type pressing structure and belonging to the technical field of transformer manufacturing process. The invention has the technical scheme that a hydraulic pump (1) is connected with a hollow hydraulic oil cylinder (2); the hollow hydraulic oil cylinder is arranged above a pressing sleeve (3); a tensioning screw (4) passes through the hollow hydraulic oil cylinder and the pressing sleeve; one end of the tensioning screw is connected with a reactor iron core pull rod (5); the reactor iron core pull rod passes through a butterfly spring (6); and the pressing sleeve is pressed on the butterfly spring. In the process that the hydraulic pump is pressurized to make the hollow oil cylinder jacked, the pressing sleeve downwards presses the butterfly spring at the upper part of an iron core through a reacting force to compress the butterfly spring; the nut of the reactor iron core pull rod is downwards screwed, and when a required pressing force is reached, the nut is screwed down to complete the compression. In the invention, a hydraulic pump station and a hollow hydraulic oil cylinder are arranged, and thereby, the integral reactor body can be pressed at high quality. The pressing device has the characteristics of simple and convenient operation, accurate pressure adjustment, high safety, work efficiency improvement, product quality improvement and the like and can reliably ensure the pressing force required by the integral shunt reactor body pressing.

Description

[0001] Technical field: [0002] The invention relates to an integral press-fitting device for a body of a shunt reactor, which is particularly suitable for a shunt reactor with a pull-rod press-fit structure, and belongs to the technical field of transformer manufacturing technology. Background technique: [0003] As we all know, shunt reactors will generate a very large vibration force during operation, which will also generate a lot of noise, which will bring many adverse effects to the product's operating quality and operating environment. In order to overcome the negative vibration force of the reactor, it is necessary to ensure effective and reliable press-fitting of the reactor body as a whole during the manufacturing process of the reactor, which is also a difficult point that must be solved in the manufacturing process of the shunt reactor. and key points. For shunt reactors with a tie-rod press-fit structure, the traditional pressure beam method is used for compre...
