[0002] An isolation transformer is a transformer with electrical isolation between the input winding and the output winding. The isolation transformer is used to avoid accidental contact with live parts. The isolation of the transformer is to isolate the current of the primary and secondary windings. It was used in the power industry in European countries in the early days, and is widely used in the control power supply, safety lighting and indicator light power supply of general circuits in the electronics industry or industrial and mining enterprises, machine tools and mechanical equipment;

For this reason, we propose a highly waterproof isolation transformer box. Utility Model Content

The fixing frame 31 is fixed to the upper side of the interior of the box body 1, and a sealing cover 32 is placed on the upper side of the fixing frame 31. The sealing cover 32 is connected by four bolts 33. A rubber sealing frame 34 is fixed to the lower side of the sealing cover 32. A card slot is provided on the upper side of the box body 1, and the rubber sealing frame 34 is carded in the card slot.

During normal use, the interior of the box body 1 is dissipated through the evenly distributed air vents 43. At the same time, the humidity sensor 35 will check the external humidity. When it rains, the external humidity rises. When the humidity value exceeds the data stored in the external PLC controller, the external PLC controller will automatically turn off all the electromagnets 56. At this time, all the springs 54 will open and squeeze the U-shaped frame 52 to move upward. The U-shaped frame 52 drives the two tooth plates 57 to move upward to drive all the gear rings 42 to rotate. The rotation of all the gear rings 42 drives all the rotating tubes 41 to rotate and seal all the heat dissipation ports opened on the left side of the box body 1. After sealing, rainwater can be prevented from entering the interior of the box body 1.
