Due to the special production process of the transformer, even the aluminum coil transformer, the terminal is connected with a copper-aluminum joint, and is wrapped by an insulating material, straight view, the exposed terminals are copper.

Isolation transformers belong to a safe power supply, generally used for machine repair, maintenance, protection, lightning protection, filtering.

The so-called overcurrent If it means that the transformer input current is overflow, there may be the following reason:

The main function of the isolation transformer is to completely insulate the electrical light on the secondary side, and the loop is isolated. In addition, the high frequency loss of its core is used to suppress high frequency clutter incoming control circuits.

The transformer iron heart magnetic flux is related to the exerted voltage. In the current, the excitation current does not increase as the load increases. Although the load is not saturated, the resistance loss of the coil will increase, exceeding the rated capacity due to the heat generated by the......
