There are counters of various types.First of all, they differ in phases. It is also important to consider the number of terminals. The type of meter determines the wiring diagram of the device. Still need to consider the place of connection of the device. In order to understand this issue in more detail, it is necessary to consider in detail specific types of meters and wiring diagrams.
Single-phase meter circuit in the apartment
Connection diagram of the electric meter (single phase)involves the use of a single modulator. Resistors in this case are necessary through passage type. If we consider the model at 20 A, then the expander can be used of the switching type. In some cases, filters are connected. Thus, overloads from the network do not affect the performance of the device.
If we consider modifications to 30 A, thenexpanders are suitable only operational type. The current conduction parameter of them must be at least 4.8 microns. In this case, much depends on the sensitivity of the modulator. In the standard panel it is set to 3 mV.
Connect two phase meter
Wiring diagram for two-phase electric meterType contains two-channel conductors. If we consider the usual 25 A model, then one expander is needed to connect the device. Most often it is applied with a facing. The conductivity parameter in the circuit is at least 5.7 microns. It is also important to note that the threshold resistance indicator depends on the sensitivity of the modulator. The connection scheme of the meter at 30 A is different. First of all, it should be noted that the expander is used without facing. In this case, the threshold conductivity of the current is at the level of 10 microns.
Three Phase Counter Features
Connection diagrams of three-phase electricity metersAlways assume the use of a wired expander. If we consider the standard shield with a modulator, then the device is connected through the contacts of the tetrode. There should be three total resistors in the expander.
In this case, the threshold conductivitycurrent should be at least 5.5 microns. The sensitivity of the modulator depends on the accuracy of stabilization of the counter. If we consider the device at 20 A, then they have the specified parameter does not exceed 2%.
Schemes of two-tariff modifications
Connection diagram of the electric meter (two-tariff)has a pass type resistor. Transceivers in the circuit, as a rule, are used with two plates. If you believe the experts, it is better not to use tetrodes. To stabilize the output voltage, it is more expedient to use network type filters. However, if we talk about meters at 25 A, then in this case we need two rectifiers. Transceivers in the circuit are used with adapters. Some experts recommend selecting transistors with insulators only.
Features of three-tariff meters
Connection diagram of the electric meter three tariffType implies the use of an expansion relay. The resistors in the circuit are applied to two conductors. The device is connected via contactors. In some cases, a regulator is used. If we consider the standard shield with a modulator, then the filter is not required.
Two terminal device layout
Electric meter wiring diagram for two terminalscan not do without extender. Very often it is applied with two plates. Transistors are installed on insulators. Some experts believe that the use of filters is inappropriate. First of all, they significantly reduce the threshold current conduction parameter. Also with filters, stabilization accuracy drops. In normal condition, it is 3%. If we consider the standard model 25 A, then the thyristor can be connected to the wired type. In some cases, it is replaced by a conventional regulator.
Three-terminal device diagram
The connection scheme of the counter on three terminals is prettyis simple. In total, it has three extenders. If we consider a standard shield with a modulator, the regulator is used with one lining. The transceiver is connected to the panel only after the transistor. Some experts believe that it is inappropriate to use filters. First of all, they strongly affect the conductivity of the current.
The threshold parameter is also significantly reduced.load. However, if we consider counters at 20 A, then the filters are considered very useful. First of all, they allow to solve the problem with abrupt voltage fluctuations in the network and increase the accuracy of equipment stabilization.
Four terminal models
Connection diagram for four terminalsincludes not only a modulator, but also pass-through resistors. Tetrode is most often used open type. However, in this case, much depends on the conductivity of the device. If we consider the device at 25 A, then the tetrode should be selected with a semiconductor. However, before its connection is installed facing with insulators. Some experts recommend the use of special extenders.
Sometimes they are replaced by triggers.In order to avoid sudden voltage surges, contactors are needed. These elements are connected directly through the terminals. If we consider the device at 30 A, then the modulator is used only field type. In the first place, this has a positive effect on the threshold conductance of the current. It is also important to note that the element greatly helps in improving the accuracy of stabilization. Insulators are standard installed with plates. The regulator is allowed to use without a resistor. In this case, the current conduction index will not exceed 6 microns.
Scheme counter "Mercury"
Connection diagram of the electric meter "Mercury"involves the use of two modulators. The extender for the model is applied resistive type. Some experts recommend installing it only after the modulator. In this way, problems with overloading capacitors can be avoided.
If we consider the standard flap on the trigger,then it is more expedient to install filters through the type. Many experts believe that the tetrode can increase the conductivity of the current. However, it is important to bear in mind that the accuracy of stabilization of the device is significantly reduced.
ACE 2000 counter
Connection of the electric meter and ACE 2000 automatic machinesoccurs thanks to the modulator on three adapters. An amplifier is used with a winding. There should be two regulators in the circuit. Tetrode in this case is used condenser type. If we consider a two-digit panel with an output trigger, then it is more expedient to select a modulator of an open type. Transistors are installed behind the plate.
Diagram of the model NIK 2102
Connecting an electric meter in the apartment includesnot only the modulator, but also the pulse transistor. There are two transceivers in the circuit. Directly modulator is used open type. However, before connecting it, all terminals are connected.
In this case, the threshold resistance should notexceed 60 ohms. In some cases, the current conduction index reaches 5 microns. If we consider the capacitor-type flap, then in this case the modulator is selected with the lining. In total for connection two extenders are required. The transceiver is commonly used open type.
Diagram of the model ME172
Connection of the electric meter through transformerscurrent involves the use of a conventional modulator with low conductivity. The trigger for the chain is selected vector type. In total for connection three connectors are required. They have a current conduction parameter of 20 microns. If we consider the capacitor shield, the modulator is used with the plates. This element is connected via output contactors. The expander for the device is applied with the lining.
Connection of MTX1A10 model
Wiring diagram for this type of meterinvolves the use of an open modulator. In total, the circuit has two connectors. The current conduction parameter is about 12 microns. In total for connection two tetrodes are required. However, if we consider the capacitor shield, the modulator is used with a lining. First of all it will help reduce the level of output voltage.
In this case, the threshold resistance leveldepends on the transceiver. Many experts recommend installing it without facing. The regulator is applied with contactors. The device is connected via output terminals.
