Abstract

The connection of the pulse circuit separator of the measuring set solves the transmission of time pulses or pulses of electricity consumption from the electricity supplier's measuring set to the auxiliary device for the control of electricity consumption of the customer. The wiring enables the transmission of pulses while maintaining the condition of complete electrical separation of the supplier's measuring set and customer's auxiliary equipment. The connection also allows the transmission of the time pulses to the auxiliary device even when their passage for controlling the indicator of the active meter is blocked by the rate switch. ■ Part of the solution is also one of the possible variants of the pulse separator, realized on the basis of optoelectric separation of circuits.

Description

The invention relates to engagement; Electricity for connection technical '

Large customers and medium-sized customers are obliged to observe the agreed values of electricity consumption from this consumption, control computers, etc./. connection to the driver time pulse of the electricity supplier. Direct drink is inadmissible due to unauthorized interference.

Consumers are, in terms of the basic conditions of electricity supply, electrical power and electrical work. To monitor and control the reason for the customers various auxiliary devices / indicators To ensure the proper functioning of these devices it is necessary to ev. pulses of consumption electrical work measuring sets drawers auxiliary equipment from circuits of measuring sets supplier advises measuring set functions and probability increase

The current method of pulse transmission while ensuring complete electrical separation of circuits is realized by means of a relay. Although this is a simple method, it has quite a number of disadvantages. The switching contacts of the relay are subject to corrosion, whereby an error can be introduced into the measurement by not transmitting the pulse to the auxiliary device. At a higher pulse rate, faults occur due to the limited lifetime of the relay. In the event of a relay coil failure, the fault is usually transmitted to the measuring set. The higher power consumption of the relay is also negligible. When using the relay of the electricity supplier's set, ensure that the time pulses are transmitted even outside the peak tariff zones set on the tariff switch.

The above mentioned disadvantages of the full set according to the invention, whose measuring sets are on output pulses on whose output terminals further to obtain time pulse switches bridged by expanding c does not allow operation of meter relays m <pulses to auxiliary equipment from work are output terminals pulse whose output terminals are connection removes the connection of the pulse separator circuits of the measuring period is that for the separation. Time pulse rate switch terminals connected separator input terminals is connected auxiliary equipment consumer electricity, even outside the tariff peak times set on the tariff zone of the tariff zone of the tariff switch resistor that Lxima active electricity meter of the supplier, however, allows the transfer of the creditor, further in that in order to separate the pulses of consumption of the electric dream electricity meter connected to the input terminals of the pulse Atelier of electricity.

Clez is that it allows the transmission of pulses from the measuring set j of the electricity consumer in a contactless manner, while maintaining the circuit breakdown. The use of non-contact switching ensures the lifetime of the device. Due to the minimum power consumption of wires connected to the power supply circuitry of the electricity supplier, it can be reliably prevented from transmitting a possible treatment failure. The wiring allows the transmission of time pulses even at the time when the active meter's measurement kit supplier blocked.

The advantage of wiring according to the manufacturer's supply to the auxiliary equipment of the condition of complete electrical o high reliability of imp transmission of the primary part of the pulse separator can be used highly selective pulse separator on the measuring room. In the Fig. 2, this block diagram is supplemented with pulses even at the time when there is a block diagram of the pulse circuit separator measuring the electrical work needs for the supplier's measuring set.

The circuit according to the invention is a block diagram of a sepa time pulse of a rate spin so that the transmission of time electricity is blocked and in Fig.

One of the possible connections In Fig. 1, there are two pulse separator terminals on the output terminal of the Active Meter's maximum electricity meter, per electricity consumer. In Fig. 2, to the terminals of the rate switch 1t of the pulse separator of the measuring circuit is shown in Fig. 4.

y of the rate switch 7, parallel to the input terminals of the relay u · 2. 1, the auxiliary device 5 is connected from FIG. 1 supplemented with a resistor 5 connected to bridge the break contact of the tariff zone.

In Fig. 3, the input terminals of the pulse meter 15, parallel to the pulse meter 7 for evaluating the electricity consumption of the electricity supplier, are connected to the input terminals of the pulse generator 34, the output terminals of which are connected to the input terminals of the electricity consumer auxiliary device.

FIG. 4 shows one of the possible connections of the pulse separator. The pulse separator consists of a primary circuit in which the pulse of the supplier's measurement kit is 220 V /

220 V / 50 Hz ev. 100 V / 50 Hz rectified and current limited to the value needed to excite the luminescent diode of the optoelectric coupler and the secondary circuit, which are used to transmit pulses to the subsidiary device of the customer. The primary circuit is formed by a fuse Po, which protects the supplier's measurement kit in the event of a pulse separator failure, the resistor R ^ limits the circuit current to the value required to energize the indicating diode and the optoelectric coupler O.

The diode rectifies the AC voltage one way and the capacitor C filters the AC component. The optoelectric coupler 0 diode light beam energizes the optoelectric coupler output transistor 0, which energizes the pulse separator output transistor T. The resistor serves to limit the current switched by transistor T.
