Technical Field

[0001] The utility model relates to the technical field of voltage transformers, and specifically relates to a voltage transformer that is easy to disassemble. 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 line failure occurs. 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] There are two types of installation environments for voltage transformers, outdoors and indoors. In the outdoor environment, due to the changeable weather, the bolts set at the installation position of the voltage transformer will rust. And usually, the number of fixing bolts is large, resulting in a long disassembly time required during maintenance, and the maintenance efficiency is too slow. Therefore, we urgently need a voltage transformer that is easy to disassemble to solve the above problems. Content of the Utility Model

[0008] Preferably, the stabilizing mechanism includes a mounting plate fixedly installed on the rectangular plate. One end of a protection plate is fixedly installed on the mounting plate, and the other end of the protection plate is fixedly installed with the upper cover plate.
