Problems solved by technology

[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 ra...

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.

Example Embodiment

[0018] As shown in the figure, this embodiment includes a base 7 , and a workbench 12 is provided in the middle part of the front part of the upper surface of the base 7 . The bases 7 on both sides of the workbench are lower than the workbench 12, and the guide rails 11 arranged in the front and rear directions are respectively installed thereon, and the sliding seats 10 are respectively matched with the two guide rails 11, and the movable parts 9 are installed above each sliding seat 10. The splint 13 has a fixed splint 6 on the base 7 corresponding to the position of each movable splint 13 . On both sides of the rear of the base 7 there is a laterally moving cylinder 8, the piston rods of which are respectively connected with the sliding seat 10 on the same side to control the front and rear movement of the movable splint 13, so as to further enable the movable splint 13 to connect with the fixed splint on the same side 6 is fitted on both ends of the sample 9 to clamp the sample 9 so that its position is fixed.
[0019] At the placement position of the sample 9 to be tested, the workbench 12 of this embodiment has a groove, in which a temperature sensor 17 is embedded, and its wires are drawn out through the perforations on the workbench.
[0020] A group of uprights 4 are installed at the rear of the base 7 , and to ensure stability, four uprights are used in this embodiment. A mounting plate 17 is fixed above the upright column 4 , and the mounting plate 19 is provided with a guide hole, a displacement sensor through hole and a piston rod through hole. The piston rod perforation is located at the front of the mounting plate 19 , the mounting plate 19 is equipped with a pressurized cylinder 20 , and the piston rod (ie, the pressurizing rod 16 ) of the pressurized cylinder 20 passes through the lower end of the mounting plate 19 and is sequentially installed with a load sensor 15 and The pressure plate seat 5 and the pressure plate 14, wherein the load sensor 15 can be a spoke type load sensor. Its specific structure is as follows: the lower part of the pressure rod 16 is provided with a protruding platform, the screw rod 17 penetrates through the lower end of the pressure plate seat 5 , passes through the load sensor 15 and is screwed to the lower end of the pressure rod 16 . The upper end surface of the load cell 15 is engaged with the projection on the pressing rod 16 . The pressure plate 14 in this embodiment is connected to the pressure plate seat 5 through a dovetail groove structure that cooperates with each other. A vertical guide rod 2 is installed at the rear of the platen seat, and the lower end of the displacement sensor 3 is also installed on the platen seat 5 . The mounting plate 17 is covered with a cover 1 , which covers the pressurizing cylinder 20 , the displacement sensor 3 and the upper end of the guide rod 2 .
[0021] In use, the dovetail groove structure can be used to replace the appropriate pressure plate 14 according to the condition of the sample 9 . Manipulate the lateral movement cylinder 8 to make the movable splint 13 and the fixed splint 6 cooperate to fix the sample 9 . Then, the sample 9 is pressurized by the pressurizing cylinder 20, the pressure on the sample 9 is measured by the load sensor 15, the displacement of the sample 9 under different pressures is measured by the displacement sensor 2, and at the same time, the temperature sensor 17 is used to measure sample temperature. Thereby, the parameters of the sample 9 are obtained, so that the analysis can be used to adjust the relevant parameters in the transformer production process, so as to improve the quality of the transformer.
