Description

Technical Field

[0001] The utility model relates to the technical field of medium wave transmitters, in particular to a special anti-leakage device for medium wave transmitters. Background Art

[0002] Generally, medium wave broadcasting uses amplitude modulation. Unknowingly, MW and AM are equated. In fact, MW is just one of the many broadcasts that use AM modulation. Medium waves can be transmitted in the form of surface waves or sky waves, just like long waves.

[0003] A Chinese patent discloses a leakage protection device dedicated to a medium wave transmitter, with publication number CN214851196U, which includes a medium wave transmitter body, a mounting frame, a current measurement component, a data processing component and a leakage protection component. The mounting frame is installed on one side of the medium wave transmitter body through a snap plate and a bottom support plate, and the current measurement component, the data processing component and the leakage protection component are installed on one side of the mounting frame through a placement plate.

[0004] However, there are still the following disadvantages: once the transmitter device of the anti-leakage device dedicated to the medium wave transmitter cannot be regulated and causes leakage, the protection valve on the leakage protection component will automatically open the switch, and then shut down the power to the equipment. However, it is not ensured whether the connected components are still energized after the power is cut off. Rashly disassembling the device and other components may also cause electric shock safety problems. Therefore, a special anti-leakage device for medium wave transmitters is designed.
