Description

ELECTRICAL DISTRIBUTION TABLE EQUIPPED WITH A CONTROL MODULE

TECHNICAL FIELD OF THE INVENTION

The present invention relates to an electrical distribution board for example installed in an individual, in a company or in a factory.

BACKGROUND TECHNOLOGY

It is known from the state of the art a switchboard which is a system from which the electric current is managed and distributed in the home, business or factory. This switchboard is usually installed in a box that also includes an electric meter and a circuit breaker. This distribution board notably makes it possible to connect the electrical network electrically by means of connections to equipment. These connections are usually configured manually.

It is known from the patent application FR2891093A1 to provide the circuit breaker with an electronic release 3, said trigger comprising at least one current sensor 4, an actuator 6, and an electronic processing unit 5 for controlling said actuator. The electronic processing unit comprises means for controlling the state of connections of the at least one current sensor 31; 44, 45 and / or actuator 161, 164, and display means 32; 166 of the operating state of the trigger, the control means acting on the display means for displaying the connection status of the at least one current sensor and / or the actuator.

The trigger of the patent application FR2891093A1 therefore comprises means for displaying its operating state and control means of the actuator.

It is known from the utility model CN202150641, a distribution of alternating current using a distribution board and a monitoring device in the form of integrated screen. The integrated screen is for example a touch screen and offers a current monitoring and a main monitoring. In this system, a redundant current supply and a control of the two current arrivals are provided by means of supervision connected to a main controller 15 itself connected to a touch screen 16.

However, it is not intended to act directly on the states of the switches of the switchboard.

It may be desirable to improve this distribution board by increasing user interactivity and ease of use.

OBJECT OF THE INVENTION

The object of the invention is to respond to this desire while at the same time remedying at least one of these aforementioned drawbacks.

According to the invention there is provided an electrical distribution board comprising:

at least one phase wire; a neutral wire; a plurality of terminal pairs, each pair of terminals comprises a so-called terminal phase terminal intended to be electrically connected on the one hand to an electrical equipment and on the other hand to said at least one phase wire and another terminal known as terminal neutral means intended to be electrically connected on the one hand to said electrical equipment and on the other hand to the neutral wire; a plurality of pairs of switches, each of the pairs of switches corresponds to a pair of terminals, for each pair of switches, a switch is arranged between a phase terminal of the corresponding pair of terminals and said at least one wire of phase and another switch is disposed between the neutral terminal of the corresponding terminal pair and the neutral wire;

a module for measuring said phase currents between a phase terminal and said at least one phase wire; a module for measuring the currents known as neutral currents between a neutral terminal and the neutral wire; and

a module for controlling the state passing or blocking pairs of switches. According to a general characteristic, the distribution board comprises a computer and a touch screen, said computer being able to act on the control module according to the measurements. phase and neutral currents and instructions received by the touch screen.

The electrical switchboard can thus be easily, intuitively and safely controlled using the touch screen via a computer and a control module, the control module making it possible to control the states of the switch couples of the switchboard.

According to other characteristics taken separately or in combination:

the computer comprises a memory for storing current thresholds, each of the current thresholds being associated with a pair of terminals and the computer is configured to trigger via the control module, the locked state of the pair of switches corresponding to the pair terminals for which a measured phase current and / or neutral current exceeds its current threshold. This is achieved by going to the off state when the intensity exceeds a threshold, a security that allows the electrical disconnection of the electrical equipment when the current that enters or exits exceeds a certain threshold. In particular, short-circuits and fire risks are reduced. Of course this threshold will depend on the application and the equipment and it is different for each of the equipment. Moreover, it can be provided that the computer can modify each of the current thresholds, for example using the touch screen.

the computer is configured to trigger, via the control module, the blocked state of the pair of switches corresponding to the pair of terminals whose sum of the measured phase current and the measured neutral current exceeds a threshold. For a given pair of terminals, the phase current and the neutral current are opposite. Thus, the sum of these two currents corresponds to the difference of their absolute value or of their amplitude. By controlling this difference in absolute value or amplitude, it is possible to trigger an electrical disconnection of an electrical equipment when the current which enters it is too different from the current coming out of it. This reduces the risk of electrocution.

the computer comprises a memory for storing, for each of the pairs of terminals, a priority number, the calculator comprises an adder of the absolute values of the measured phase currents in order to determine the power consumed in real time, and the computer is configured to trigger via the control module, the off state of the on-state switch couple corresponding to the lowest priority number terminal pair if the power consumed is greater than a threshold. It is thus possible to limit the maximum power consumption and using priority numbers, the electrical disconnection will be performed on a pair of low priority terminals that are connected to equipment whose use is not essential. It can be provided that the computer can modify these priority numbers, for example in the case where one changes the equipment connected to the pairs of terminals or according to a different use.

the calculator comprises a time module for determining the current time.

This module provides access to the time which is a parameter that is interesting to take into account to control the states of the switches.

the computer comprises a memory for storing for each of the pairs of switches of a part of the plurality of pairs of switches at least a couple of hours, a pair of hours comprising a closing time and a time of opening and the computer is configured to trigger via the control module, the blocked state of a pair of switches in the on state if the current time is between a closing time and an opening time. This results in an electrical disconnection programmed according to the time. For example, it could be expected that all pairs of terminals will be disconnected at the same time. Alternatively one could define in the memory schedules according to each of the pairs of terminals or provide that only a portion of the terminal pairs could be disconnected. Of course, the computer can modify all the hours of opening and closing contained in this memory to adapt them to the uses.

the computer comprises a memory for storing the measurements of the measured phase and neutral currents and their time for each of the pairs of terminals.

It is thus possible to carry out a posteriori follow-up of the currents consumed to detect a malfunction of an electrical equipment or a bad use or electrical equipment whose consumption is too important.

the phase current measuring module comprises for each of the at least one phase wire a phase current measurement unit, the neutral current measurement module comprises for each of the at least one phase wire a measurement unit neutral currents, the control module comprises for each of the at least one phase wire a switch torque control unit, the distribution board comprises for each of the at least one phase wire, a first microcontroller forming for a phase wire the unit of measurement of the phase currents and the distribution board comprises for each of the at least one phase wire, a second microcontroller forming for a phase wire, the unit for measuring the neutral currents and the control unit.

It is thus easy to set up with the aid of microcontrollers a measurement of the phase and neutral currents as well as a control of the state of the switches. one of the first or second microcontrollers comprises a receiver for receiving network information from an electricity meter connected between an electrical supply network and the distribution board electrical, said microcontroller comprising the receiver being configured to communicate to the computer said network information and the computer is configured to trigger via the at least one second microcontroller, the locked state of at least one of the plurality of pairs of switches according to said network information.

Thus, depending on the network information that is coming from the electrical network, it is possible to disconnect one or more electrical equipment selectively in order to save electricity. The network information relates in particular to a first period and a second period during which the price of KWh billed by the operator of the electricity network is different. For example, the price is higher during the second period. It is therefore possible, taking into account this network information, to automatically trigger a disconnection when the second period begins, which makes it possible to reduce consumption during a period during which the electricity is billed more expensive.

the electrical distribution panel comprises a touch pad forming the computer and the touch screen.

It is thus possible to provide a touch screen for the distribution board with an advantageous cost given the strong development of touch tablets. For example, it can be provided that the touch pad executes a specific software to play the role of calculator.

the at least one second microcontroller is connected to the touch pad.

The connected tablet can control the second microcontroller that transmits its measurements. It can also be provided for example that the second microcontroller receives the measurements of the first microcontroller and the second microcontroller transmits the measurements of the two microcontrollers, ie the phase currents and neutral currents to the tablet. For example, the tablet is connected to the second microcontroller by USB interface according to an acronym well known to those skilled in the art that is widespread. the electrical distribution board includes a module for communicating wirelessly and acquiring an internet address.

It is thus possible, for example, to allow the user to receive information on the current operation of his distribution board. It is also possible after secure access to a remote control of the user on its switchboard.

-the touch pad forms the module to communicate wirelessly and acquire an internet address.

This is an embodiment whose cost is competitive given the high degree of industrialization of tablets.

the computer is configured to associate a set of switch couples comprising at least one pair of switches, with electrical equipment to be powered so that the switches of the set of switch couples all have the same blocked state or passing.

It is thus possible to control at the same time the connection or disconnection of the phase and neutral terminals of a set of terminals. This is advantageous when this set of terminal pairs is connected to the same electrical equipment. According to a first example, in the three-phase case, the electrical equipment is connected to two pairs of terminals, the two pairs having phase terminals connected to different phases, which allows in particular to deliver a greater voltage. More precisely 380 volts in the case of a three-phase voltage of 220 volts. According to a second example, in the three-phase case, the electrical equipment is connected to three pairs of terminals, the three pairs having phase terminals connected to different phases, which makes it possible, in particular, to supply it with a three-phase voltage of 220. volts for example.

the touch screen is configured to display an interface comprising: a plurality of pair of icons, each pair of icons including an equipment icon representing an electrical equipment to power and a switch icon, pressing the switch icon of a pair of icons triggering the off or on state of the set of switch pairs associated with the electrical equipment represented by the equipment icon of said pair of icons;

a general switch for triggering the blocked state of the plurality of pairs of switches.

This is a simple but effective interface that illustrates most of the possible interactions with switchboard switches. For example, it can be provided that the touch pad executes specific software to play the role of calculator and also to display this interface.

a touch screen 1 15;

two modules for measuring currents 1 1 1 and 1 13; a calculator 1 10; and a switching element 1 14.

The switching element 1 14 comprises: a plurality of terminal pairs 141;

a plurality of pairs of switches 142, each of the pairs of switches corresponding to a pair of terminals 141. The computer 1 10 is configured to associate a set of switch couples 142 to an electrical equipment 1, 2, 3, 4, 5 to supply, the set of switch couples comprising at least one pair of switches. Thus, the switches of the set of switch couples all have the same blocked or on state. For example, as illustrated in FIG. 3, a couple of switches 142 are associated with the electrical equipment 1, that is to say the washing machine 1, a pair of switches 142 at the electrical socket 3 and a couple of switches 142 to the bulb 4.

Two pairs of switches 142 are associated with the electrical equipment 5, ie the water heater 5. Likewise, three pairs of switches 142 are associated with the electrical equipment 2, that is to say the air conditioner 2. It is thus possible to control at the same time the connection or the disconnection of the two pairs of terminals connected to the water heater 5. It is also possible to control at the same time the connection or the disconnection of the three pairs of terminals connected to the air conditioner 2. It will be described here. after more in detail a pair of terminals 141 and its corresponding pair of switches 142, knowing that the other pairs of terminals and their pair of switches are similar to this one.

The pair of terminals 141 comprises a terminal 141a said phase terminal intended to be electrically connected firstly to an electrical equipment 5 and secondly to the said phase wire L and another terminal called neutral terminal 141b intended to be electrically connected on the one hand to the electrical equipment 5 and on the other hand to the neutral wire N.

The pair of switches 142 comprises a switch 142a which is disposed between the phase terminal 141a of the corresponding terminal pair 141 and the phase wire L and another switch 142b which is arranged between the neutral terminal 141b of the pair of 141 corresponding terminals and the neutral wire N.

The control module 1 12 can control the on or off state of the pairs of switches 142, each of the pairs of switches comprising a switch 142a between the phase terminal 141a and the phase wire and a switch 142b between the terminal neutral 141b and the neutral wire. To ensure this control, the control module comprises a switch torque control unit 1 12a.

The measurement module 1111 is capable of measuring the so-called phase current between the terminal 141a intended to be connected to the phase wire L and the phase wire and is called the phase current measuring module. For this, the measuring module of the phase currents 1 1 1 comprises a unit of measurement of the phase currents 1 1 1 a.

Similarly, the measurement module 13 is capable of measuring the so-called neutral current current between the intended terminal 141b to be connected to the neutral wire N and the neutral wire and is called the neutral current measuring module. For this purpose, it comprises the neutral current measurement module 13 comprising a unit for measuring the neutral currents 13a.

Figure 4 shows components of a distribution board 101 according to the first embodiment of the invention. These components make it possible in particular to implement the functional blocks: control units, units of measurement of the phase currents and units of measurement of the neutral currents illustrated in FIG.

The distribution board 101 comprises for the phase wire L, a first microcontroller 123 forming for the phase wire L, the measurement unit of the phase currents 1 1 1 a.

For this purpose, for example, the microcontroller 123 comprises an ammeter for each of the pairs of terminals 141. In this case, for each of the pairs of terminals, the microcontroller 123 comprises a wire through which the ammeter is connected between the phase terminal 141a and the phase wire L. The distribution board 101 also comprises for the phase wire L, a second microcontroller 1 16 forming for a phase wire L, the neutral current measuring unit 1 13a and the control unit 1 12a.

For this, on the one hand the microcontroller 1 16 comprises for example an ammeter for each of the pairs of terminals 141. In this case, for each of the pairs of terminals, the microcontroller 1 16 comprises a wire through which the ammeter is connected between the neutral terminal 141b and the phase wire N.

On the other hand, the microcontroller 1 16 also comprises two other wires for each of the terminal pairs 142. Thus, the microcontrollers 1 16 and 123 comprise, for each pair of terminals, four wires.

It can be provided that the first microcontroller 123 comprises a receiver 121 for receiving the INFO network information. In order to ensure electrical safety, it is possible to interpose an opto-coupler 122, so that the INFO network information is received by opto-coupler 122 and transmitted to the first microcontroller 123. Furthermore, the distribution board 101 comprises a wire 120 and the first and second microcontrollers are connected via the wire 120.

It is also possible to interpose an opto-coupler 124 between the first microcontroller 123 and the second microcontroller 1 16, the second microcontroller being connected to the computer 1 10.

Thus, the microcontroller comprising the receiver 121 in this case the first microcontroller 123 is configured to communicate to the computer 1 10 said network information INFO. The computer 1 10 is then able to trigger via the control module 1 12, the locked state of at least one pair 142 of the plurality of pairs of switches 142 according to said network information INFO.

In addition, the first microcontroller 123 can also transmit via the wire 120, the phase current measurements to the second microcontroller 1 16 so that the computer 1 10 can receive them. For example, a touch pad 1 18 forms the computer 1 10 and the touch screen 1 15, this touch pad 1 18 being for example connected to the second microcontroller 1 16 by a USB interface 1 17 according to a well-known English acronym for the skilled person. For example, the touch pad 1 18 forms the module 1 19 to communicate wirelessly and acquire an internet address.

FIG. 5 represents a detailed view of one of the elements of the distribution board according to the first embodiment. This is the switching element 1 14.

This switching element 1 14 comprises a midpoint 147 connected by a conductor 145 to the neutral wire N and by another conductor 146 to the phase wire L.

The switching element 1 14 comprises a plurality of terminal pairs 141, at each pair being associated a pair of switches 142. A pair of terminals 141 and its pair of associated switches 142 will be described in greater detail below, knowing that the other pairs of terminals and their pair of switches are similar to this one.

The pair of terminals 141 comprises a terminal 141a said phase terminal intended to be electrically connected firstly to an electrical equipment 5 and secondly to the phase wire L and another terminal 141b said neutral terminal intended for to be electrically connected on the one hand to said electrical equipment 5 and on the other hand to the neutral wire N.

The pair of switches 142 corresponding to the pair of terminals 141 comprises a switch 142a which is arranged between the phase terminal 141a of the corresponding terminal pair and the phase wire L and another switch 142b which is arranged between the neutral terminal 141 b of the corresponding terminal pair and the neutral wire N.

The switching element 1 14 comprises between the switch 142a and the phase wire L, a conductor 144. It also comprises between the switch 142b and the neutral wire N, a conductor 143. The conductors 143, 144, 145 and 146 are shown in Figure 5 as a resistor because their operation from an electrical point of view is modeled by a resistor. As already mentioned above, for each pair of terminals 141 and its pair of switches 142 there are four wires, one from the first microcontroller 123 and three from the second microcontroller 1 16.

The wire from the microcontroller 123 is connected between the conductor 144 and the switch 141a. This wire also connected to the ammeter of the microcontroller 123 dedicated to the terminal pair 141 can thus capture a voltage proportional to the phase current between the phase terminal 141a and the phase wire L to allow the deduction of the phase current between the phase terminal 141a and the phase wire L. The first wire from the microcontroller 1 16 is connected between the conductor 143 and the switch 141b. This wire also connected to the ammeter the microcontroller 1 16 dedicated to the terminal pair 141 can thus pick up a voltage proportional to the neutral current between the phase terminal 141b and the neutral wire N to allow the deduction of the neutral current between the neutral terminal 141b and the The other two son coming from the microcontroller 1 16 are connected to the terminals of an electric coil 148. These two son allow the supply of the electric coil 148. The electric coil 148 is then able to act on a electromagnetic element 149 of the pair of switches 142 to move it and change the state of the pair of switches 142. Figure 6 shows an interface 150 displayed by the screen 1 15 of the distribution board according to the invention. This interface 150 includes:

a general switch 151 for triggering the off state of the plurality of pairs of switches 142; and

a plurality of icon pairs 154.1, 154.2, 154.3, 154.4, 154.5. Each pair of icons 154.1, 154.2, 154.3, 154.4, 154.5 includes an equipment icon 153.1, 153.2, 153.3, 153.4, 153.5 representing electrical equipment to be powered and a switch icon 152.1, 152.2, 152.3, 152.4, 152.5 . Pressing the switch icon 152.1, 152.2, 152.3, 152.4, 152.5 of a pair of icons 154.1, 154.2, 154.3, 154.4, 154.5 triggers the off or on state of the torque set of switches 142 associated as mentioned with reference to Figure 3, the electrical equipment 1, 2, 3, 4 or 5, said equipment being represented by the equipment icon 153.1, 153.2, 153.3, 153.4 or 153.5 of said pair of icons 154.

As can be seen on the interface 150: the icon 153.1 represents the equipment 1, namely the washing machine;

the icon 153.2 represents the equipment 2, namely the air conditioner;

the icon 153.3 represents the equipment 3, namely the electrical socket;

the icon 153.4 represents the equipment 4, namely the bulb; and

the icon 153.5 represents the equipment 5, namely the water heater. In the case of an association as described in FIG.

- Pressing the icon 152.1 which will cause the blocked state of two pairs of switches 142 and the electrical disconnection of two pairs of terminals 141, those connected to the square 1 in Figure 3;

- Pressing the icon 152.2 which will cause the blocked state of two pairs of switches 142 and the electrical disconnection of two pairs of terminals 141, those connected to the square 2 in Figure 3;

- Pressing on the icon 152.3 which will cause the blocked state of a pair of switches 142 and the electrical disconnection of a pair of terminals 141, the one connected to the square 3 in Figure 3; and

- Pressing the icon 152.4 which will cause the blocked state of a pair of switches 142 and the electrical disconnection of a pair of terminals 141, the one connected to the square 4 in Figure 3; and a pressing on the icon 152.5 which will cause the locked state of two pairs of switches 142 and the electrical disconnection of two pairs of terminals 141, those connected to the square 5 in FIG.

Figure 7 shows a diagram of a computer 1 10 for a distribution board according to the invention. This computer 1 10 may comprise a memory 21 1 for storing current thresholds, each of the current thresholds being associated with a pair of terminals 142. In addition, the computer 1 10 is configured to trigger via the control module 1 12, the off state of the pair of switches 142 corresponding to the terminal pair 141 for which a measured phase and / or neutral current exceeds its current threshold.

For example, independently of this memory, it can be provided that the computer 1 10 is configured to trigger via the control module 1 12, the blocked state of the pair of switches 142 corresponding to the pair of terminals 141 whose sum of the current of measured phase and current of Neutral measured exceeds a threshold. It is then a current threshold common to all the pairs of terminals 142.

This computer 1 10 may comprise a memory 212 for storing for each of the pairs of terminals 141, a priority number. The computer 1 10 may then include an adder 213 of the absolute values of the measured phase currents in order to determine the power consumed in real time. In this case, the computer 1 10 is configured to trigger via the control module 1 12, the blocked state of the pair of switches 142 in the on state corresponding to the lowest priority number of the terminal pair 141 if the power consumed is greater than a threshold. It is then also a power threshold common to all the pairs of terminals 142.

This calculator 1 10 may comprise a time module 214 for determining the current time. This may be for example an electronic module operating with quartz crystals.

The computer 1 10 may then comprise a memory 215 for storing for each of the pairs of switches of a part of the plurality of pairs of switches 142 at least a couple of hours, a pair of hours comprising a closing time. and an opening hour. In addition, the computer 1 10 is configured to trigger via the control module, the blocked state of a pair of switches 142 in the on state if the current time is between the closing time and the opening time.

For example, it could be expected that for a portion of the pairs of switches 142, the memory comprises a couple of hours. In this case, each terminal torque will be disconnected when the current time is between the closing time and the opening time of the pair of switches corresponding to the terminal torque.

Alternatively one could predict that for a portion of the pairs of switches, the memory comprises for example three couples of hours. In this case, there would be for the pair of terminals corresponding to the pair of switches three connection periods. For the pairs of switches for which a couple of hours are not stored, then there is no provision for disconnection of the terminal pair corresponding to this switch torque.

Still in the case where the computer comprises a time module 214 for determining the current time, it can be provided that the computer 1 10 further comprises a memory 216 for storing the measurements of the measured phase and neutral currents and their time. for each of the pairs of terminals 141.

Figure 8 shows a detailed diagram of a distribution board according to a second embodiment of the invention. This embodiment differs from the first embodiment in particular in that it comprises three phase wires L1, L2 and L3 instead of just one L.

Thus, the module 1 1 1 for measuring the phase currents comprises for each of the three phase wires L1, L2, L3, a unit of measurement of the phase currents 1 1 1 a, 1 1 1 b, 1 1 1 c. Similarly, the module 13 for measuring the neutral currents comprises, for each of the three phase wires L1, L2, L3, a unit for measuring the neutral currents 1 13a, 13b, 13c. And finally, the control module 1 12 comprises for each of the three phase wires L1, L2, L3, a switch torque control unit 1 12a, 1 12b, 1 12c. In other words, according to this second embodiment, with three phase wires L1, L2 and L3 is provided for each of the three phase wires:

a control unit 1 12a, 1 12b or 1 12c;

The distribution board 101 illustrated in FIG. 9 differs from that illustrated in Figure 4 from a different number of phases namely three instead of one, most other elements remaining identical.

Thus, the distribution board 101 comprises for each of the three phase wires L1, L2, L3, a first microcontroller 123a, 123b, 123c. Each of the first three microcontrollers form, for one of the three phase wires L1, L2, L3, the unit for measuring phase currents 1 1 1 a, 1 1 1 b, 1 1 1 c. In addition, the distribution board 101 comprises for each of the three phase wires L1, L2, L3, a second microcontroller 1 16a, 1 16b, 1c forming for a phase wire L1, L2, L3, the unit of measure neutral currents 1 13a, 1 13b, 1 13c and the control unit 1 12a, 1 12b, 1 12c.

With three phases, the distribution board 101 comprises three wires 120 for connecting the first microcontroller 123a, 123b or 123c of a phase wire L1, L2 or L3 to the second microcontroller 1 16a, 1 16b or 1 16c of the same phase wire L1, L2 or L3.

The three wires 120 each make it possible to connect the first microcontroller of a phase wire L1, L2 or L3 to the second microcontroller of the same phase wire L1, L2 or L3. It is also possible to interpose an opto-coupler 124a, 124b or 124c between the first microcontroller of a phase wire L1, L2 or L3 and the second microcontroller of the same phase wire L1, L2 or L3, the second microcontrollers being connected to the calculator 1 10.

For example, the computer 1 10 is formed by a touch pad 1 18 which also forms the touch screen 1 15. This touch pad 1 18 is for example connected to each second microcontroller by a USB interface 1 17 according to an acronym saxon well known to those skilled in the art. For example, the touch pad 1 18 forms the module 1 19 to communicate wirelessly and acquire an internet address. One of the first microcontrollers for example 123a includes a receiver

121 to receive the network information INFO. In order to ensure electrical safety, it is possible to interpose an optocoupler 122, so that the INFO network information is received by the opto-coupler

122 and transmitted to the first microcontroller 123a. FIG. 10 represents a detailed view of one of the elements of the distribution board according to the second embodiment. This is the switching element 1 14.

Thus, the terminal pairs 141 and the corresponding switch couples 142 are identical to those illustrated in FIG. 5. However, a difference lies in the fact that the phase terminals 141 have terminal pairs 141 are not all connected to the terminal. same phase wire L but on one of the three phase wires L1, L2 or L3. In addition, it is provided that the switching element 1 14 comprises a midpoint 147a, 147b, 147c for each phase wire L1, L2 and L3. The mid-point 147a is then connected by a conductor 145a to the neutral wire N and by another conductor 146a to the phase wire L1. The midpoint 147b is then connected by a conductor 145b to the neutral wire N and another conductor 146b to the phase wire L2. The midpoint 147c is then connected by a conductor 145c to the neutral wire N and another conductor 146c to the phase wire L3.

The conductors 143, 144, 145a and 146a, 145b and 146b, 145c and 146c are shown in FIG. 10 as a resistor because their operation from an electrical point of view can be modeled by a resistor.
