Description

Technical Field

[0001] The utility model relates to the technical field of voltage transformers, and particularly relates to a voltage transformer with stable connection. Background Technique

[0002] A voltage transformer is similar to a transformer and is an instrument used to transform voltage. However, the purpose of a transformer to transform voltage is to facilitate the transmission of electric energy, so its capacity is very large, generally calculated in kilovolt - amperes or megavolt - amperes; while the purpose of a voltage transformer to transform voltage is mainly to supply power to measuring instruments and relay protection devices, to measure the voltage, power and electric energy of a line, or to protect valuable equipment, motors and transformers in the line when a fault occurs in the line. Therefore, the capacity of a voltage transformer is very small, generally only a few volt - amperes or dozens of volt - amperes, and the maximum does not exceed one thousand volt - amperes.

[0003] Currently, the connection between a voltage transformer and an external circuit usually uses a terminal and a wire nose for connection, mostly fixed by a threaded connection method. However, because the voltage transformer will generate vibrations during operation, the thread and the fixing nut may become loose during vibrations, resulting in an unstable connection between the wire nose and the terminal. Moreover, when using a nut for fixing during long - term use or during installation and disassembly, rusting or slipping of the thread may occur. Therefore, we urgently need a voltage transformer with stable connection to solve the above problems. Content of the Utility Model
