Definitions
- the invention relates to the field of high and medium voltage disconnector control devices, and more particularly relates to a device and a method for controlling a control signal intended for a disconnector and representative of a maneuver order, such as that opening and closing of the disconnector.
- a disconnector is a device provided with one or more movable members, placed in open position, to electrically isolate a section of a line of an electrical network, for example for human intervention safely on this isolated line section.
- the disconnector is coupled to a control device adapted to actuate the movable members according to the operating commands received. More specifically, the direction of movement of a movable member is determined by the configuration of a power supply circuit of a motor driven by a control unit. Examples of control devices are detailed in documents FR 2 931 995 and FR 2 904 469 of the Applicant.
- Maneuver commands ie the opening and closing orders of the disconnector, usually come from a control panel, or more generally from a disconnector maneuver management system. These operating commands are typically generated by the control panel from an AC or DC voltage source, for example from the power grid.
- the power supply of the motor for a sufficient duration makes it possible to ensure the displacement of the movable members to cause either the opening or the closing of the disconnector.
- the disconnector having no breaking capacity, that is to say that it is not able to automatically interrupt and under prescribed conditions, the current flowing, the electrical equipment downstream of the network It is essential that the electric disconnect switch be shut down before the disconnector is operated to prevent the disconnector from opening while the electric arcing due to the opening can cause damage. Similarly for obvious safety reasons, it is absolutely imperative that the disconnector does not close unexpectedly.
- the present invention proposes an inexpensive solution which makes it possible to reinforce the security in taking into account these orders of maneuver.
- the object of the invention is thus a device for controlling at least one analog or continuous type analog control signal generated from an electrical network and intended for controlling a disconnector.

- the template is created taking into account the characteristics of the electrical signal generated by the electrical source, as well as parameters previously stored and specific to the corresponding order of maneuver. The characteristics are for example the shape, the frequency, and the parameters can be an amplitude, a duration.

- the analog command signal generated by the remote control can be received on an input of the device dedicated to receiving an opening command. This control analog signal is previously processed as described above and then compared to the expected template. If the control signal conforms to the expected template, the control device generates a validity indicator of the opening order, and if not it can generate an error indicator.
- the expected template representative of an opening order may be an alternating type signal characterized by a peak amplitude and a number of periods.
