Electrified detection alarm device of low tension distribution box shell

The utility model discloses an electrified detection alarm device of low tension distribution box shell, take electric detection means including establishing at the peripheral non -contact of block terminal shell, non -contact takes electric detection means to include detecting element, and this detecting element is used for detecting block terminal shell electric field signal, this detecting element is connected with the amplifier circuit electricity, and amplifier circuit's power end and DC power supply electricity are connected, and amplifier circuit's output is connected with emitting diode's negative electricity, and emitting diode's positive pole is connected through buzzer and DC power supply's anodal electricity, after detecting element detected the electrified electric field of block terminal shell, the transmission signal of telecommunication was given amplifier circuit, the signal of telecommunication drive after amplifier circuit amplifies that emitting diode is luminous, sound is emitted to the buzzer. Taking place to miss ground, earth connection broken string at the block terminal shell, lose the condition of preventing the protection that the person electrocute under, the utility model discloses send the electrified acousto -optic warning of block terminal shell, it is dangerous to let people can not take place the electric shock, has improved the security of block terminal operation.
