TECHNICAL FIELD

[0002] In the operation and metering field of a power system, an instrument transformer plays an indispensable role, and the stability and reliability of the performance directly relate to the accuracy of power metering and the safe operation of the power system. In the production and manufacturing process of the instrument transformer, the welding link between the primary side copper bar and the copper piece on the end button of the meter bottom shell is crucial, and the quality of the welding will directly affect the work efficiency of the instrument transformer and the entire power metering system. In order to effectively improve the weldability of the welding process and ensure the firmness and stability of the welding connection, the industry generally adopts the method of adding a welding sheet between the two. The welding sheet is usually composed of silver solder or amorphous solder and other materials with excellent welding auxiliary performance, which can reduce the welding temperature and remove the oxidation film on the metal surface, thereby ensuring the quality of the welding joint.
