Abstract

The invention relates to electrical measuring equipment and can be used in information and measuring systems for metering electricity. The purpose of the invention is to improve the accuracy by eliminating the false alarms of the device at low speed of rotation of the electric power meter disk. The introduction of optocoupler keys 13, 14 and element 2 OR-HE 7, as well as the formation of new functional connections, allows one to achieve the set goal. The device also contains an electricity meter with a disk 1, a light absorbing spot 2, a pulse generator 3 and a driver-amplifier 4, the first and second triggers 5 and 6, the photosensors 8 and 9 optically connected through the surface of the disk are applied to the light reflecting surface. Illuminator 10, the third and fourth triggers 11 and 12. 2 Il.

Description

of the darkening zone (time t4) with a disk 25, on the reflective surface, after which, when a next radiation pulse appears, at the output of the 2Hrof-HE 7 element there is a single spike of a single signal and the output trigger 11 returns to its initial state

If the voltage of rotation of the disk 1. does not change, then with its further rotation the cycle of operation repeats

Rotating the disk in the opposite direction, which corresponds to the opposite direction of energy flow, causes the photo sensors 8 and 9 to work in reverse order and a signal is generated at the input of the switch 14 (fig.2, right part of the timing diagram).

If a disk oscillates at the instants when the photosensors enter the flare or dark areas,

whose lightness is applied a light absorbing spot, successively connected a pulse generator and a shaping amplifier, the first output of which

30 are connected to the clock inputs of the first and second triggers, the information inputs of which are connected to the outputs of the corresponding photosensors optically coupled through the surface of the disk to the illuminator, connected to the second output of the amplifier, and the third trigger, The key is connected to the output of the second trigger, and the information input is connected to the output of the first trigger and the clock input of the fourth trigger, whose information input is connected to the output of the second trigger, which is different

vibrations, for example, and if these vibrations lead to the formation of pulse bursts at the outputs of the photosensors, the circuit of the proposed device eliminates the possibility of error

Thus, in a pinged device, output signals, depending on the direction of rotation of the disk, are generated either on the + bus (with a direct flow of electricity, or on the bus - (with a reverse flow of electricity, while ensuring the accuracy of converting the i-drive) into a pulse signal at
