Embodiment:
See figures.1.and.2, dc power supply circuit is made up of storage battery and solar cell, and the solar cell output of series connection is connected on series connection storage battery two ends behind two diodes, provide charge power supply by solar cell.
Because this device is installed on the electric conductor equipment; nickel-cadmium cell combines so solar cell that working power employing 5 joint models are BPY64 to be in series and rechargeable 4 joints are connected; the power supply of output voltage 4.5V～6.5V; make this device not need to change battery and can not cut off the power supply all the time; this power supply also is provided with under high light the protection loop to over-charging of battery, and under the low light level battery to the protection loop of solar-electricity tank discharge.
Its realization principle is seen shown in Figure 2: VD1, VD2 are two series diodes, and model 2AK10 is used to prevent under the low light level, and dry cell is to the protection loop of solar-electricity tank discharge.Voltage-stabiliser tube VZ and two OP1, OP2 light are formed a protection loop that under high light dry cell is overcharged every reaching resistance.When at the low light level, solar array voltage is lower, can't puncture voltage-stabiliser tube (6.2V～7.5V), OP1 is by R1, the conducting of R3 loop, led lighting, make the ab conducting, power so a batteries of solar battery group high potential sealed in the solar battery group, when under high light, solar battery group voltage raises, voltage-stabiliser tube is punctured, and OP2 is by VZ, the conducting of R2 loop, led lighting, make the cd conducting, short circuit OP1 so ab disconnects, excises a batteries of solar battery group high potential.In sum, during the low light level, 5 node solar battery groups all drop into power supply; During high light, has only the power supply of 4 node solar battery group inputs.Can play under high light the protective effect that dry cell is overcharged like this.Switch S 1-1, S1-2 LED 1 play start and the effect that monitors.
With reference to Fig. 1 and Fig. 3, by forming by filter circuit, operational amplification circuit, rectification amplifying circuit and light pipe, light pipe output switching value is given logic module to described high-voltage alternating sampling module successively.Wherein:

The rectification amplifying circuit is made up of diode VD3 and triode VT1, VT2;
The light pipe adopts two OP1, OP2 to be in series, and exports two switching values respectively and gives logical circuit.
High-tension apparatus is when putting into operation, because dielectric exists capacitance current and earth leakage current over the ground, this device mainly is sampling capacitance electric current and leakage current signal, but this signal is very weak, and clutter is arranged, so this device carries out filtering to this signal, export to logical circuit after the amplification.Its realization principle is seen shown in Figure 3: because this device is directly installed on the electric conductor, monitor the electriferous state of electric conductor, the electric conductor in the electrical network has many interference signals, is on the point of signal, electromagnetic wave signal and other noise signals etc. as carrier signal, height.Particularly electric conductor is in ground state and high-impedance state, and the interference of these signals may cause the false triggering action of circuit, and cause erroneous judgement disconnected.Based on above consideration, see shown in Figure 3, after input signal is on the point of filtering through capacitor C 1 height earlier, form a 50ZH band pass filter by resistance R 5, R6, R7, capacitor C 2, C3 again, by the IC1 operational amplifier, be input to after the rectification of diode VD3 after VT1, VT2 amplify once more, the light pipe OP3 of control two series connection, OP4 light every two switching values of output to logical circuit.Can largely improve the antijamming capability of this device like this, capacitor C 4 is that the signal after the rectification is carried out filtering, adds just from deviator for triode VT1 to form direct voltage.
