Hereinafter, the operation of the cremor having the photoelectric transducer according to the present invention will be described.

When the breaker 30 is normally operated, the generated electric power is input to the (+) and (-) terminals, which are the input terminals of the photoelectric converter 50 of the transmitting end,

The power inputted to the (+) and (-) terminals, which are input terminals, is converted by the LD into a part of electric power, and is converted into light through the optical cable of the hybrid cable 40 through the optical terminal, At the same time, the power branched from the node and the node of the LD is supplied to the surge circuit protection unit 55 connected in parallel, and at the same time, the (+) terminal of the output terminal, which is the power output terminal of the transmitter photoelectric adapter 50, (-) terminal of the hybrid cable 40 to the covered wire 41 of the hybrid cable 40.

(-) terminal which is the output terminal of the photoelectric adapter 60 at the receiving end.

The power generated by the pulse generator 30 is transmitted to the electric primer 20 by the flow of the electric power and the optical signal as described above so that the electric primer 20 is operated and the electric primer 20 is operated, 10 is made to operate normally.

Hereinafter, the operation of the surge circuit protection unit 55 inside the transmission-side photoelectric adapter 50 will be described.

When power noise is introduced into the hybrid cable 40 due to disturbance, these diodes can not be conducted due to the diodes connected in the reverse direction among the first to fourth diodes of the heat dissipation adapter input terminal 60, The GDT operating voltage is applied and the current flowing into the heat dissipation adapter input terminal 60 is directly supplied to the electric primer 20 through the electric wire 40 so that the Cremor operates normally.

Next, the power noise generated by the disturbance, such as a lightning stroke, will flow through the hybrid cable 40 to either the (+) or (-) terminal, which is the output terminal of the transmission and photoelectric adapter 50.

At this time, if the noise input to the (+) terminal of the transmission and photoelectric adapter 50 is a positive power noise, the introduced power noise is discharged to the ground through the second SPD through the positive power noise first diode, If the polarity power noise is above the TVS operating voltage, it is connected to SPD 1 through TVS and is discharged to the ground. Also, if the magnitude of the positive polarity power noise is above the GDT operating voltage, GDT also works together to generate positive power noise Cremora will not operate due to release to the ground.

Also, if the incoming power noise is input to the positive (+) terminal of the transmission and photoelectric adapter 50, the negative power noise is discharged to the ground through the first SPD through the second diode, and furthermore, If the noise is above a certain range, it is connected to the SPD 2 through the TVS if it is above the TVS operating voltage. If the negative power noise level is above the GDT operating voltage, the GDT also works together. And cremora will not operate.
