Abstract

A telecontrol equipment item (10) is adapted to monitor the MV network (3) at the level of a transformer substation and possibly control elements (5) thereof in the case of a fault. According to the invention, the equipment item (10) comprises means (400) for also monitoring the LV network (4). Preferably, the equipment item (10) comprises an LV monitoring module (400), a power supply module (100), a communication module (200) and an MV monitoring module (300_i) for each line to be monitored. The different components of the modules are optimized to be adapted to the networks (3, 4) on which the equipment item (100) is installed, and to allow for updates.

Claims

1. Telecontrol equipment (10) for an MV/LV substation (6) between a medium-voltage network (3) and a low-voltage network (4) comprising:

first means (100) for powering said equipment (10) from the low-voltage network (4) and from an auxiliary source (105);

second means (200) for communicating the information gathered by said equipment (10) to the outside;

third means (300) for monitoring the medium-voltage network (3) at the substation (6) level;

fourth means (400) for monitoring the low-voltage network (4) at the substation (6) level.

2. Telecontrol equipment according to claim 1, in which the first means (100) and/or the second means (200) and/or the third means (300) and/or the fourth means (400) are formed by a module comprising a casing (110, 250, 310, 430) housing electronic means adapted to fulfil the function of the respective means (100, 200, 300, 400).

3. Telecontrol equipment according to claim 2, in which the electronic means comprise means for being able to be updated.

4. Telecontrol equipment according to claim 2, in which the third means (300) are formed by a plurality of similar modules each comprising a casing (310) housing electronic means adapted to monitor a line of the medium-voltage network (3).

5. Telecontrol equipment according to claim 2, in which the second, third and fourth means (200, 300, 400) comprise a casing (250, 310, 430) provided with means for fixing onto a DIN rail (34) and the profile of which is similar, said casings 30 being able to be attached according to a constant pitch to form a row.

6. Telecontrol equipment according to claim 5, in which the first means (100) comprise a casing (110) provided with means (122, 128) for fixing on a wall mount and provided on a face (116) opposite said fixing means with a DIN rail (140) onto which the casings (250, 310, 430) of the second, third and fourth means (200, 300, 400) can be installed.

7. Telecontrol equipment according to claim 5, in which the casings (250, 310, 430) of the second, third and fourth means (200, 300, 400) comprise a nose (52) opposite the means for fixing onto the DIN rail (34), said nose (52) comprising a human/machine interface (268, 340, 440) making it possible to indicate the main functions of the respective module.

8. Telecontrol equipment according to claim 1, in which the fourth means (400) comprises electronic means making it possible to measure the current, the voltage, the energy and/or the power of the low-voltage network (4).

9. Telecontrol equipment according to claim 8, in which the fourth means (400) are associated with a set of three current sensors (410) which can be placed on a line of the low-voltage network (4A, 4B, 4C), said sensors (410) being self-powered, and communicating wirelessly with said fourth means (400).

10. Telecontrol equipment according to claim 9, in which the fourth means are associated with a plurality of similar sets of three current sensors (410), and the electronic means of the fourth means (400) are adapted to synchronize the measurements of said sets (410) such that the fourth means (400) are able to monitor a plurality of lines of the LV network (4).

11. Telecontrol equipment according to claim 8, in which the electronic means of the fourth means (400) are adapted to indicate a fault transition, monitor the balancing of the loads and/or measure the frequency in the LV network (4).

12. Telecontrol equipment according to claim 8, in which the electronic means of the fourth means (400) are adapted to monitor the transformer of the substation (6).

13. Telecontrol equipment according to claim 1, comprising series power supply connection systems from the first means (100) to the second, third and fourth means (200, 300, 400), the second means (200) serving as relay for the power supply for the third and fourth means (300, 400).

14. Telecontrol equipment according to claim 1, in which each of the first, third and fourth means (100, 300, 400) are linked to the second means (200) by a series connection, said second means (200) ensuring the communication within the telecontrol equipment (100) and with the outside.

15.
