- the IED comprises a base 16 fixed in the low-voltage cabinet, conventionally on a rail, acting as a terminal terminal with the wires 14 for connection to the equipment 10.
- this base 16 can be plugged boxes 18 which contain external signal acquisition members 20, which are connected to the junction terminals of the base 16 by pins 22.
- the external signal acquisition means 20 transmit the present or absent state of the equipment 10 to the through a communication, typically digital, 24 which connects the base 16 to the central unit 2 ': to allow communication between the central unit 2' and the withdrawable module 18, a communication connector 26 is provided.
- the information communication 24, 26 further transmits the power required for the operation of the external signal acquisition means 20; optionally, signaling lights powered according to the state of the acquisition members 20 may also be installed on the housing 18.
- the invention aims to overcome the drawbacks of existing protection or control / command equipment, in that the information acquisition inputs from the external devices are deported to the interface modules and no longer integrated in the central unit or the base.
- the module remains fully operational when disconnected and its proper operation can be verified, for example by setting up a test bench simulating the presence or absence of external signals.
- the invention relates to a group of DI modules, in particular able to receive information relating to external devices, each of the modules comprising: an electrical connection device to a data bus, in particular a connection wire to the external device; a signal acquisition member from the data bus, possibly coupled to a control member of said data bus, for example a low-voltage relay with signaling contacts or means for detecting information relating to the wires, in particular in the form of printed circuit board; and a communication device receiving the information from the acquisition member, and possibly able to activate the control member according to the received signal, also for example in the form of a printed circuit board.
- the modules are housed in a housing of the control group and / or control, said housing comprising a connector adapted to route the control and / or control signals between the communication devices and a central unit.
- the invention relates to an intelligent electronic apparatus which comprises, in addition to the preceding electronic unit of modules, a base provided with a housing adapted to receive the housing of the modules, connectors adapted to be connected to each of the connection devices when the electronic group is received in the base and connected to a junction terminal to the connecting wires of the external devices.
- the invention finally relates to equipment comprising at least one intelligent electronic apparatus and a central unit capable of exchanging information with the communication devices of the electronic group or groups.
- the equipment may be a remote management equipment in which the acquisition members comprise means for determining information relating to the apparatuses by their connecting wires and the central unit is able to supervise said apparatuses, or a protective equipment in which relay modules of the switchgear can be activated, open or closed, by the central unit.
- FIGS. 1A and 1B already described, illustrate the apparatus according to two embodiments of the prior art.
- Figure 2 shows a control / control apparatus according to one embodiment of the invention.
- FIG. 3 shows an equipment according to a preferred embodiment of the invention.
- an IED 30 comprises several modules 32, identical or not, which are housed in a common housing 34.
- Each module 32 comprises an external signaling acquisition member 36, optionally coupled to a control member 38, emerging from the housing 34 by connecting means 40, for example a sliding male / female contact.
- the members 36 may be mounted on a printed circuit board.
- the connection means 40 are indirectly connected to the equipment 10 controlled by the IED 30 when the module 32 is plugged into a suitable support.
- the IED 30 comprises a base 42 provided with a housing 44 in which the housing 34 can be inserted.
- the base 42 is fixed in the low-voltage cabinet, and it comprises junction terminals 46 enabling the to connect to surrounding low voltage equipment 10 including insulated copper son 48; the terminals 46 may for example be screwed connections.
- the signaling information from the wires 48 is transmitted to a central unit 50 by a communication device 52 which is directly integrated with the housing 34 of the electronic module group 32; the communication device 52 may be in the form of a printed circuit board, separate or coupled to that of the external signaling acquisition member 36.
- the connection can be made by any means, in particular via a digital link.
- the base 42 no longer contains a communication connector, neither to the central unit 50 nor to a module 32 or the plug-in box 34: the external signaling acquisition members 36 transmit the information acquired via a link 54 which is directly connected to the housing 34 by a communication device 52, for example via a connector 56, even if a wireless link can be provided.
- the insertion of the module 32 in the base 42 is accompanied by the only connection of the external signaling acquisition members 36 by a power connector 40, as opposed to a communication connector which only transits very low voltage signals.
- the external signaling acquisition relays 36 are still operational since the digital communication between the unit 50 and the housing 34 is not interrupted: it is possible to test the proper operation of this housing 34 even when it is removed from its base 42, which allows for example to check the change of state of organs acquisition of external signaling 36 without any interference on equipment connected to the son 48, especially during commissioning or maintenance operations.
- the equipment is suitable for protection, as well as for control / command and remote management.
- the central unit 50 may moreover comprise a plurality of communication ports 58 which may each connect to an intelligent electronic apparatus 30, 30 'which are similar to one another or different if other functions are to be performed. Regardless of the number of communication ports 58, the connection to a group of input modules DI is made via a communication cable 54 of small section, whose installation time is much lower than that of the copper wires used for individual DI modules as illustrated in Figure 1A.
- the solution according to the invention therefore offers the advantage of allowing easy connection, at a lower cost, while retaining the individual test options of the DI 32 modules without connection to the primary equipment or external equipment 10. These gains in time and cost In addition, there is a saving in copper, the use of which is minimized at essential connections. In addition, since the electrical supply connection 40 and the communication connection 52 of the IED 30 intelligent switchgear are located in two separate separable parts, housing and base, the electronic control and / or control unit remains operational when a disconnection of the IED 30, and the control / control modules 32 may for example be tested.
- the invention has been described with reference to a control equipment and / or control, including protection, with DI relays, it is not limited to: other elements may be concerned by the invention.
- the wires 48 can pass other types of information, for example analog signals of the order of 4 to 20 mA, and the communication link 52, 54 may be adapted to provide the CPU 50 with information relating to these other types of signals, for example to form a network remote management equipment.
- the equipment according to the invention can be adapted to remotely manage installations of WAGES type (for "Water, Air, Gas, Electricity and Steam"), that is to say check parameters relating to industrial engines in applications in the field of water (pumps %), air (air conditioning, %), gas (valves, %), electricity, steam, or parameters climatic and environmental aspects for the management of engines for renewable energy production facilities.
