The invention relates to an elastic crimping device for calibrating a current transformer. A lower contact component for crimping the current transformer is fixed on a baseplate; a vertical shaft is fixed on a baseplate; the middle part of a rotating arm can be rotationally arranged on the vertical shaft; a lifting screw rod is screwed on the front straight section of the rotating arm; a pressing plate is fixed on the lower end of the lifting screw rod; a circular force applying plate is arranged below the pressing plate, and a second pressing spring is arranged between the circular force applying plate and the pressing plate; an upper contact component which matches with the lower contact component of the baseplate to actuate is fixed on the bottom surface of the circular force applying plate; and a first pressing spring is arranged between the rotating arm and the baseplate. The elastic crimping device has the characteristic of convenience of operation and reliable crimping function and is suitable for calibrating the current transformer of a power system.
Description
technical field [0001] The invention relates to a fixing device for checking a current transformer, in particular to a spring-type pressure fixing mechanism for checking a current transformer in a power system. Background technique [0002] When the power system verifies the low-voltage current transformer, because the equipment manufacturer does not provide the crimping device for the connection of the current transformer, the traditional connection method uses connecting devices such as hand vise and electric welding pliers, which are inconvenient to use, cumbersome to operate, low in efficiency, and current mutual inductance There are defects and problems such as poor contact between devices, and easy heating when high current is used. Contents of the invention [0003] The object of the present invention is to provide an elastic crimping device for crimping reliable current transformer verification. [0004] The object of the present invention is achieved in the follo...
