Compression ratio measuring device

Abstract

The invention relates to a compression ratio measuring device. The compression ratio measuring device comprises a base, wherein a workbench is arranged on the upper surface of the base, and a clampingmechanism, a pressurizing mechanism and a measuring mechanism corresponding to the workbench are further arranged on the base; the clamping mechanism comprises a transverse air cylinder arranged on the base, and a piston rod of the transverse air cylinder is fixedly connected with a sample piece movable clamping plate; the pressurizing mechanism comprises a pressurizing mechanism body and a pressing disc connected with the pressurizing mechanism body, and the pressurizing mechanism body is installed on the workbench through a stand column; and the measuring mechanism comprises a displacementsensor corresponding to a movable part of the pressurizing mechanism, a pressure sensor matched with the pressing plate and a temperature sensor capable of being matched with the sample piece. The compression ratio measuring device can provide a basis for increasing and decreasing cushion blocks of a coil in the production process of a transformer, the former height adjustment after coil forming is advanced to a winding process, the number of the cushion blocks is increased or decreased during winding, the coil is not damaged, a large amount of labor cost can be saved for each transformer, theproduction efficiency is improved, and the construction period is shortened.

Description

technical field [0001] The invention is a compression ratio measuring device. Background technique [0002] At present, in the manufacturing process of transformers, reactors, etc., it is a worldwide technical problem that the axial height is difficult to control due to changes in the compression ratio of laminates, coil pads, and wires. The actual compression is caused by differences in ambient temperature, humidity, and insulation manufacturers. The difference between the ratio and the theoretical data is the biggest problem that plagues us, which greatly affects product quality and production progress. To re-adjust the height of the coil, it is necessary to pry up the wire cake to increase or decrease the pads, which takes up a lot of man-hours, low labor efficiency, easy to damage the insulation, and brings new hidden dangers to the product quality. Contents of the invention [0003] The object of the present invention is to design a compression ratio measuring device...
