Definitions
- the present invention relates to the field of distribution and transformation of electrical energy, and more specifically to an adapter, for application at a connection point between a high-voltage electrical equipment and at least one measuring means, control and protection Said adapter allows the measuring, control and protection means to be connected with at least one bar of the main bar set of the high voltage electrical equipment, regardless of the type of connection element existing in the high voltage electrical equipment, maintaining the same element of existing connection so far.
- the electrical equipment or high-voltage cells used in electrical power distribution facilities, for maneuvering and / or protection of the electrical network comprise different compartments, such as the cable compartment where the cables can be received of connection or can be given out to other distribution facilities.
- measurement, control and protection means such as voltage sensors, voltage transformers, means for receiving / transmitting signals via PLC, means for detecting partial discharges can be installed in the cable compartment of an electrical equipment, current sensors, etc.
- measuring, control and protection means such as means that provide voltage and intensity values, such as inductive toroidal sensors for intensity measurement and resistive / capacitive sensors for voltage measurement, are installed in the connection between the cables previously mentioned and high-voltage electrical equipment by means of connectors (for example T-connectors) that are installed in the field, since the cables are previously installed.
- the captured signals are conditioned and processed in a Electronic data acquisition system for protection, measurement and / or control.
- each of these electrical equipment comprises measurement, control and protection means installed in the cable compartment, the signals being captured by each of the means of measurement, control and protection received by electronic relays that are installed integrated to the high voltage electrical equipment itself. Therefore, each high-voltage electrical equipment is generally provided with measuring, control and protection means, as well as an electronic relay.
- each of the electrical equipment comprises its own electronic relay associated with its own measurement, control and protection means, which implies the need to use at least one measurement, control and protection means for each electrical equipment that is available in a distribution installation, which implies larger electrical equipment and ultimately more space needed for the distribution installation, greater wiring, as well as higher costs.
- US201 Patent Application 10025342A1 deals with a T-connector that can be connected to an electrical equipment bushing through its first open end.
- the connector may be connected by its second open end to a device or said second open end may be isolated by a plug. Its third open end is configured to receive a power cable and a voltage pick-up point is also provided on this third end of the connector.
- International Patent Application WO02080308A2 also refers to a connection system by means of a T-connector, which allows current and voltage to be captured at the same connection point between the cable and the electrical equipment.
- the system comprises an inductive toroidal sensor for intensity measurement, a resistive sensor for voltage measurement, a shielded connector, a fixed connection base (electrical equipment bushing) and electronic signal acquisition equipment.
- the current sensor is supported on the fixed base of the connection, and the voltage sensor is integrated into the detachable T-connector, specifically at one of its open ends, without modifying the characteristics of the high-voltage connection.
- Patent EP2253963B1 deals with a solution for connection of measuring, control and protection means on the main busbar of a high-voltage electrical equipment. It is a particular connection, with an adapted connector, which thanks to several connection interfaces allows an electrical connection to be established by contact between flat surfaces.
- This particular type of connection is developed for use in bar sets that have a flat configuration, that is, a non-standard configuration. It is therefore the object of said patent EP2253963 B1 to simplify the connection of a measuring device of an electrical magnitude with an element of a power line, of the connection bar, cable or terminal type, whose connection interface is flat and compressible. Therefore, this type of connection has the disadvantage that it can only be used in installations with bar sets and connection elements with a particular and non-standard configuration, which means that the distribution installation is more expensive.
- the present invention solves the aforementioned drawbacks by providing an insulated high voltage adapter intended to be used at a connection point between a high voltage electrical equipment and at least one means of measurement, control and protection, allowing a connection with a high degree protection (insulated and shielded), and simultaneously a connection that can supply voltage and current values at the connection point.

In this way the problems of space in the facilities, wiring, costs, etc. are minimized.
- the only means of measurement, control and protection existing in the installation is associated with each of the electronic relays that are installed in each of the high voltage electrical equipment, and is installed, adjusted and checked at the factory, so that media installation errors are avoided due to incorrect wiring of earth meshes, polarities, etc.

- the insulating body On the opposite side of the first connection end, the insulating body comprises the second connection end, where the measuring, control and protection means can be housed in correspondence with the conductive part.
- the first outer conductive layer is grounded, so that the electric field is evenly distributed between the second inner conductive layer and the first outer conductive layer of the insulating body, thus avoiding the corona effect and possible partial discharges that may appear .
- the adapter comprises at least one conductive means inside which is at the same potential as the conductive part, thus guaranteeing control of the electric field.
- the assembly formed by the insulating body and the measuring, control and protection means is coupled to the high voltage electrical equipment through at least one mooring means comprising at least one mooring plate fixed to the side of the high voltage electrical equipment , and at least one rod that is fixed at one end to the tie plate and at the other end to at least one stop piece through a clamping element.
