Description

<Desc / Clms Page number 1>

 The present invention relates to a mobile unit comprising an electrical energy supply, at least one energy sampling point, and a device for counting / recording the electrical energy withdrawn, comprising a generator of counting pulses. , which is in effective functional connection with the energy sampling point and which generates a counting pulse per increment of energy sampled.

 In a known mobile unit of this type, a housing is, on the one hand, made in the form of a power outlet and is, on the other hand, provided with connection pins for the supply of electrical energy. In the housing are housed a pulse counter, a totalizer, as well as a display using which it is possible to directly display the electrical energy consumption of a device consuming electricity, connected to the power socket (document DE 30 33 095 Al). However, processing of the counting pulses carried out remotely from this unit in order to record, monitor or manage the consumption of electrical energy is not possible. To take counting pulses from the unit, open it and look for a connection point in the circuit arrangement. The counting pulses which can be taken from this connection point may be unsuitable, without other measures, for the remote transmission, so that it is necessary to take additional measures with regard to the construction of the circuit, in order to converting the counting pulses, in particular as regards their level, into an appropriate pulse form. However, opening the unit in order to carry out these manipulations very greatly restricts the possibility of calibrating and certifying the unit.

 However, there is an increasing need, in the case of various points of consumption of electric current, to record and monitor the energy consumption not only at the same point of consumption, but also at a distant point from the consumption point, with a view to recording consumption there, monitoring and managing it. Cases of need for smaller and movable sampling points, such as for example boxes or multiple outlet strips, are increasing, due to the fact that apart from the supply of energy from the electrical network, the more and more energy is supplied for reasons of security and availability by means of grid substitution facilities, or

<Desc / Clms Page number 2>

 backup power supply installations or generator installations.

 Also, the object of the present invention is to provide a mobile unit of the type mentioned in the introduction, which is suitable for recording the energy consumed at sampling points and consumption of variable layout and for the supply of signals for remote processing and recording, and which for this purpose may in particular be calibrated and certified.

 According to the invention, this object is achieved, for a mobile unit of the type of that mentioned in the introduction, thanks to the fact that the unit includes an interface for transmitting the counting pulses, which is in effective functional connection with the generator. counting pulses, and to which it is possible to connect directly from outside the unit.

 In other words, to reach this interface for transmitting the counting pulses, it is not necessary to open the unit or a housing of the unit, which on the contrary can remain closed and can be kept in a form calibrated and certified. The counting pulse transmission interface is functionally connected to the counting pulse generator and is designed so as to provide a counting pulse output meeting required properties, in particular the SO specifications of the German industrial standard DIN 43864. The investment for this purpose on this technical level is nevertheless reduced, because it is based on the counting pulses of the counting pulse generator, which in any case is present as an integral part of the device counting and recording integrated in the mobile unit.

 According to the invention, a mobile electrical energy sampling point is therefore combined, comprising a counting / recording indicator device which is linked to it mechanically and electrically and which allows direct reading of consumption (KW / h), to the supply of counting pulses suitable for remote transmission, with a view to processing or using them, and in particular with a view to recording consumption, at a location remote and independent of the mobile unit.

 The energy metering / recording device can preferably be prepared in a calibrated and certified manner.

<Desc / Clms Page number 3>

 Such a mobile unit can be designed not only for reading the electrical energy of a phase, but also for two or more phases, in which case there is provided for each phase, an energy metering / recording indicator device. each comprising a counting pulse generator, each of which is in effective functional connection with a counting pulse transmission interface to which it is possible to connect directly from outside the unit.

 In this case, the counting / recording indicating devices can all be housed in a box which also contains all of the energy sampling points each connected to a counting / recording indicating device, as well as the set of interfaces for transmission of counting pulses.

 However, instead of this, each counting / recording indicator device can also be placed in a box with the energy sampling point and the interface for transmission of the counting pulses associated, at least two such type of boxes. modular being mutually assembled. In the case of this variant, a box can be provided for the proper reading of the energy consumed by a phase. Several of these boxes will then be grouped according to the number of phases. This helps streamline manufacturing and inventory management.

 More specifically, the mobile unit can be produced in the form of at least one protective contact socket box comprising a cable as supplied with electrical energy. The cable normally ends with a male plug. In the case of executions with up to three phases per unit, it may however prove useful to also provide cables with free ends.

 In a particularly advantageous manner, the interface for transmitting the counting pulses comprises a connection socket fixed in the unit and comprising several contacts, to which it is possible to connect directly from outside the unit.

 As a variant, the interface for transmitting the counting pulses may comprise a built-in male connector mounted in the unit and comprising several contacts, to which it is possible to connect directly from outside the unit.

 As a connection socket or a built-in male connector, it is possible to use a connector of the usual type D-Sub-9, the pin 1 of which is

<Desc / Clms Page number 4>

 connected to a 24 V DC voltage source and whose pin 9 is reserved as a pulse output. The connection socket or the built-in male connector can not only be integrated, in each unit, once per phase, but it is also possible that a unit has a front face and a rear face, in each of which is integrated a socket connection or a built-in male connector, the two connection sockets or male connectors forming an integral part of said one interface for transmitting the counting pulses by phase. One of these two connection sockets or one of these two built-in male connectors can be used for the transmission of counting pulses and their processing / recording remotely, and the second of the two connection sockets or the second of the two Flush-mount male connectors can be used for a measure of control and functionality. It is therefore not necessary, for this latter function, to disconnect the fixed connection from the other connection socket or from the other built-in male connector, through which the counting pulse is transmitted.

 The operating state of the unit and the delivery of the counting pulses can be controlled by virtue of the fact that on a visible surface of the unit, at least one light-emitting diode (LED) is placed which signals, on the one hand, the operating state of the counting / recording device and, on the other hand, a counting pulse having been generated. If only one light-emitting diode is used for this, this should be chosen in the form of a duo light-emitting diode (LED).

 According to a favorable configuration in terms of assembly, the counting / recording indicator device and the interface for transmitting the counting pulses can be integrated with the connection socket or the built-in male connector, in a subgroup of unit, which can be inserted into the unit.

 In addition, the unit may include a rocker switch which is arranged, electrically, between the supply of electrical energy and the point of energy withdrawal.

 According to another variant, a network noise filter and a transient protection system can be arranged, electrically, between the supply of electrical energy and the point of energy withdrawal.

<Desc / Clms Page number 5>

 Instead of this or in addition, the unit can also include a protective differential circuit breaker, which is arranged, on the electrical plane, between the supply of electrical energy and an energy draw point.

 For simple mounting, for example on a chassis, fixing angles can be inserted laterally in the housing or the socket strip with protective contact, namely a fixing angle on each front side.

 protection in place of the additional overcurrent protection circuit breaker, Fig. 35 to 38 a socket outlet with protective contact comprising a device for counting / recording the energy withdrawn in the form of a single-phase alternating current, according to FIGS. 1 to 4, with however in addition a differential circuit breaker of protection and a bipolar overcurrent protection circuit breaker, instead of two protection contact sockets, Fig. 39 a plan of the connections for the counting device for recording the energy sampled in the form of a single-phase alternating current, with the counting pulse generator, and FIG. 40 a wiring diagram of the counting / recording device with the counting pulse generator, according to FIG. 39.

 In FIG. 1, the reference 1 designates as a whole, a casing or a strip of sockets with protective or earth contact, in the left front side of which (see also FIG. 4), penetrates a cable 2 comprising a male plug with protective contact not designated, for power supply, namely single-phase alternating current. Energy can be taken from protective contact sockets 3 to 9.

 On the two front sides of the protective contact socket box 1 are engaged laterally, fixing angles 10, 11, by means of which the protective contact socket box can be mounted, for example on a chassis 19 ".

 To take a reading of the electrical energy delivered, that is to say consumed, by the protection contact sockets 1 to 9, a subgroup of unit 13 with a counting / recording device 14, which comprises a counting pulse generator not shown. The counting / recording device can also be referred to as an alternating current meter. Its connection to the cable 2 and to the protective contact sockets, in particular 3, is shown in FIG. 39; a corresponding wiring diagram is shown in FIG. 40. The parts which correspond to each other are here, as in all this description, designated by the same references.

<Desc / Clms Page number 8>

 FIG. 40 suggests that the counting / recording device 14 comprises a winding of a current transformer 15, which is looped in the line of phase L and controls the generator of counting pulses not shown, of the device counting / recording.

 The counting pulse generator is connected to a passive counting pulse output, with connection terminals 16,17. The connection terminal 16 is supplied with a direct voltage of 24 V. The connection terminal 17 delivers counting pulses generated by the counting pulse generator, according to the SO prescriptions of the German industrial standard DIN 43864. To sample the counting pulses, transfer and process them at a point distant from the protective contact socket box 1, the connection terminals 16,17 of the counting / recording device are connected to a connection socket or connector 18 of the type D-Sub-9, namely at their pins 1 and 9. In addition, the connection terminals 16, 17 of the counting pulse generator are connected to another connection socket or other connector 19 of the D-Sub type. 9, which is provided for controlling the operation of the counting pulse generator. The functions or the purposes for which the connection sockets 18,19 are provided can also be reversed, depending on the conductors and devices connected to these connection sockets. The connection socket 18 is embedded on the front face of the unit sub-group 13 and is therefore accessible from the front face of the protective contact socket box 1. The connection socket 19 is, on the other hand, on the rear face of the protective contact socket box 1, as shown in Figure 2.

 The two connection sockets 18,19 therefore make available as integral parts of a transmission interface counting pulses, counting pulses which represent a measurement for the electrical energy taken globally by sockets with protective contact .

 The protective contact socket box 20 of FIGS. 5 to 8 differs from the protective contact socket box 1 of FIGS. 1 to 4, in that the protective contact socket box 20 comprises, in addition, a toggle switch 21, which is inserted in the line leading to the protection contact sockets 4 to 9.

<Desc / Clms Page number 9>

 A continuous housing of protective contact sockets 22, according to FIGS. 9 to 12, is on the other hand provided, for a three-phase connection, with a cable 23 comprising open free connection contacts. For each phase, five protective contact sockets are provided, respectively 24 to 28.29 to 33.34 to 38, in the protective contact socket box 22. In addition, each phase is associated with a subgroup of unit, respectively 39.40 and 41, which is designed as the unit subgroup 13, and each of which has two connection sockets for delivering the counting pulses, respectively 42 and 43.44 and 45.46 and 47 .

 Each of the unit sub-groups 39, 40, 41 is connected, respectively for each phase, to an unidentified counting / recording device and to a not shown counting pulse generator, in accordance with the plan of the Figure 39 connections and Figure 40 wiring diagram.

 Also part of the socket box 22, fixing angles which can be engaged laterally, respectively on the left side and on the right side of the unit, and which in FIGS. 13a, 14a and 13b, 14b, are designated respectively by 48 and 49.

 FIGS. 15 to 18 show an assembly of three socket boxes 50, 51, 52 for three individual phases. Therefore, each of the three protective contact socket boxes 50, 51, 52 is provided on the left front side, with a respective cable 53, 54, 55 provided with a protective contact plug. The three protective contact plug boxes are grouped together by side flanges 56,57.

 Each protective contact socket box has a unit subgroup 58, 59, 60 comprising an unidentified counting / recording device and a counting pulse generator, which is equipped, for each of the boxes, with connection sockets for delivering the counting pulses 61 and 62,63 and 64,65 and 66 respectively. These correspond respectively to the connection sockets 18,19 in FIGS. 39, 40 and are similarly mounted in the circuit, this for each phase.

 The protective contact socket box 67 of FIGS. 19 to 22, for the supply and reading of energy in a single phase, and of a design for the 19 "technique, corresponds substantially to the protective contact socket box 1 of FIGS. 1 to 4, but however additionally includes a filter 68

<Desc / Clms Page number 10>

 against network noise and a device 69 for protection against transients, which are inserted in the circuit, between the counting / recording device 14 and the protection contact sockets 5 to 9, without however having any influence on the counting / recording device 14 with the connection sockets 18,19.

 Correspondingly, what is valid for the protective contact socket box 67 according to FIGS. 19 to 22, is also valid for a protective contact socket box 70 according to FIGS. 23 to 26, which is not distinguished from the first cited, that by the fact that a filter 71 against interference from the network does not include a device for protection against transients. This has no influence on the counting / recording device 14 and the counting pulse generator which is connected to the connection sockets 18,19.

 In a protective contact socket box 72 according to FIGS. 27 to 30, intended to deliver and collect energy in the form of a single-phase alternating current, there is integrated a bipolar overcurrent protection circuit breaker 73, which can be placed upstream of the counting / recording device 14. For the rest, this protective contact socket box corresponds to the protective contact socket box 1 of FIGS. 1 to 4.

 In a protective contact socket box 74 according to FIGS. 31 to 34 is integrated, in place of the overcurrent protection circuit breaker 73 of the protective contact socket box 72, a differential protection circuit breaker 75, which can also be mounted upstream of the counting / recording device 14. The latter is unchanged with respect to FIGS. 1 to 4,39, 40. The protective differential circuit breaker is also bipolar.

 A protective contact socket box 76 according to FIGS. 35 to 38 comprises a differential protection circuit breaker and a bipolar overcurrent protection circuit breaker 77, and thus constitutes practically a combination of these circuit breakers 73.75 of FIGS. 27 to 30 and respectively 31 to 34. The function of the counting / recording device 14 with the counting pulse generator is the same as in the case of the protective contact socket boxes described above.
