Embodiment

[0032] Such as Figure 1-6 As shown, a high-voltage current transformer primary wiring crimping device includes a steering mechanism, a crimping mechanism and a follower mechanism.

[0033] Such as Figure 5 As shown, the steering mechanism includes a rotary cylinder 111 and a rotary cylinder mounting base plate 14. The main body of the rotary cylinder 111 is fixed on the rotary cylinder mounting base plate 14, and a spacer 19 is arranged between the two. The spacer 19 is a square spacer and can be snapped into The groove on the rotary cylinder installation base plate 14 is connected with the rotary cylinder installation base plate 14 through connecting structures such as threaded connectors, and the main body of the rotary cylinder 111 is fixed on the spacer 19 by the rotary cylinder fixing screw 112 . The output shaft of the rotary cylinder 111 is parallel to the bottom plate 14 on which the rotary cylinder is installed.

[0034] Such as Figure 4 As shown, the crimping m...

Abstract

The invention relates to a primary connection crimping device of a high-voltage current transformer. The primary connection crimping device of the high-voltage current transformer comprises a steering mechanism, a crimping mechanism and a following mechanism, wherein the steering mechanism comprises a rotary air cylinder (111); the crimping mechanism comprises a crimping air cylinder installation plate (21) and a crimping air cylinder (24); a main body of the crimping air cylinder (24) is arranged on the crimping air cylinder installation plate (21); an output shaft of the rotary air cylinder (111) is connected with the crimping air cylinder installation plate (21) through a gear transmission mechanism; the following mechanism comprises an insulating fixing block (31), a conductive copper bar fixing screw (37) and a spiral spring (34); and one end of the insulating fixing block (31) is fixedly connected with an output shaft of the crimping air cylinder (24) and an installation hole (39) is arranged in the other end. Compared with the prior art, the primary connection crimping device has the advantages that the rotating angle of a conductive copper bar is controlled by the steering mechanism, the conductive copper bar approaches a connection end through the crimping mechanism, the conductive copper bar is clung to a connection surface through deformation of the spiral spring, the contact is reliable and the crimping efficiency is high.

Description

technical field [0001] The invention relates to a crimping device for electrical equipment, in particular to a primary wiring crimping device for a high-voltage current transformer. Background technique [0002] Due to the different shapes of high-voltage current transformers, the large difference in height and volume between various voltage levels, and the large difference in the accuracy of different manufacturers in the processing process. The wiring surface of some wiring copper bars is not horizontal. For these transformers, gaps are likely to occur when the wiring is crimped once, reducing the contact area and causing unreliable contact. As a result, the primary end of the current transformer will generate a large current during the error test, and the maximum current will reach 2000A. The contact is unreliable when crimping the wire, and the increase of the contact resistance is easy to generate heat. [0003] At present, in the metering equipment used by various ele...
