Embodiment Construction

[0016] The electrical engineering basis of the present invention is that the positive and negative pole voltages output by the AC power supply network after bridge rectification are equal to 0.9 times of the bridge stack input AC voltage. However, the voltage of the positive pole of the bridge stack to the zero potential of the earth is positive 0.45 times the AC voltage, and the negative pole of the bridge stack is 0.45 times the AC voltage. The voltage of the pole-to-potential is negative 0.45 times the AC voltage.

[0017] The positive and negative poles of the AC power rectified by the bridge stack (1) are connected in series between the relay coil (2) and the D and S poles of the field effect tube (4), and the G and S poles of the field effect tube (4) are connected in parallel to boost the voltage Resistor (5) and capacitor (6). The freewheeling tube (3) is connected in parallel with the relay coil (2). The G pole of the field effect tube (4) is connected in series w...

Abstract

The invention provides a micro-current safety electronic fence which adopts a high-value resistor to limit net touching current to be below 10 milliamperes, and personal safety is guaranteed. When a person or an object touches the net and is conducted with the ground, the field effect transistor is immediately conducted, the normally open contact of the relay is closed to start the alarm, and the monitoring probe works. When net touching does not occur, only the detection circuit works to display that several light-emitting diodes which are connected and disconnected with wires work, and the total power consumption is less than 5W.

Description

technical field [0001] The micro-current safety electronic fence of the invention belongs to the field of power grids. Background technique [0002] The existing power grid adopts the technical scheme of setting two bare wires with pulsed high-voltage electricity of different polarities at a distance smaller than the human body. There are disadvantages such as easy injury, easy short circuit, and easy air discharge. Moreover, the insulation requirement is high and the cost is high. Contents of the invention [0003] The electrical engineering basis of the present invention is that the positive and negative pole voltages outputted by the bridge-type rectification of the AC power supply network current are equal to 0.9 times of the bridge stack input AC voltage. However, the voltage of the positive pole of the bridge stack to the zero potential of the earth is positive 0.45 times the AC voltage, The voltage of the negative pole of the bridge stack to the zero potential o...
