OPTICAL-ELECTRONIC SENSOR OF CURRENT AND VOLTAGE

摘要

1. An optical-electronic current sensor comprising a primary converter, an encoding unit, a communication channel between the high voltage side and the earth potential, a receiving unit and a power supply in the form of an energy transmission channel from the earth potential side, consisting of a battery of light emitters, power optical channels, a battery photodetectors and voltage stabilizer, characterized in that a shunt included in the cut of the power line is used as the primary converter for current, and a resistive divider for voltage is used voltage, consisting of a low-resistance resistor, one end connected to the wire of the power line, and the other to a group of series-connected high-resistance resistors, the last of which is attached to the traverse of the power line, the encoding unit is made in the form of two analog-to-digital converters, the input of the first analog-to-digital the converter is connected to the shunt, the input of the second analog-to-digital converter is connected to the low-resistance resistor, the common point for connecting the analog-to-digital converters is the point and the connections of the shunt and low-resistance resistor, and the outputs of the analog-to-digital converters are connected to the inputs of the parallel digital to serial code converters, to which emitting LEDs are connected, supplying light signals to the fiber-optic communication channels, their other ends are connected to the corresponding receiving units. 2. The optoelectronic current sensor according to claim 1, characterized in that a shunt is included as a primary converter for current, included in the cut of the power line, and for voltage - low resistance
