Definitions
- the invention relates to a shielded high-voltage substation element with gas insulation under a metal casing fixed to the ground, comprising at least one circuit breaker electrically and mechanically connected to at least one busbar extending in a direction transverse to the longitudinal axis of the circuit breaker.
- a high-voltage shielded substation element is understood to mean a section of this substation including at least one circuit breaker
- the metallic envelope of this element is understood to mean the overall envelope formed by the assembly of the individual envelopes of the high-voltage switchgear and bars. that make up said element.
- the metal envelope is conventionally rigidly anchored to the ground.
- This envelope generally comprises a tank surrounding the circuit breaker which extends in the direction of the longitudinal axis of the latter. This tank is surmounted by vertical nozzles, consisting for example of high-voltage connection bars in a metal casing and electrically and mechanically connecting the circuit breaker to the busbar via a common point.
- the envelope of such a post element also contains other electrical equipment such as, for example, one or more disconnectors mounted at the common point.
- the busbar extends transversely to the longitudinal axis of the circuit breaker. It is conventionally provided to mount axial bellows on the busbar to compensate for the variations in length which are due to thermal expansion. More particularly, thermal expansion appears in the busbar due to the passage of electric current and variations in the ambient temperature. This expansion is all the more important as the material normally used for the manufacture of an envelope is aluminum. For a substation comprising a busbar 30m long, the expansion of the busbar is approximately 30mm for heating up to 40 ° C.
- the axial bellows are arranged along the busbar, in order to limit the mechanical stresses undergone by the armored substation element in order to avoid in particular damage to the circuit breaker and the electrical equipment.
- the object of the invention is to propose a more economical solution to compensate for the effects of expansion of the busbar connected to the metal casing of the substation element.
- the subject of the invention is a shielded high-voltage substation element with gas insulation under a metal casing fixed to the ground, comprising at least one circuit breaker electrically and mechanically connected to at least one busbar extending along a direction transverse to the longitudinal axis of the circuit breaker, characterized in that the metal casing is fixed to the ground by means of an articulation allowing a slight pendular movement of the casing in the event of expansion of said busbar along from said transverse direction.
- the joint can be placed at ground level to be away from the busbar so as to minimize the amplitude of the pendulum movement.
- This articulation can be connected to the envelope either directly or by an intermediate support.
- the articulation consists of at least one piece or a metal section anchored to the ground and capable of bending on either side of a vertical plane substantially perpendicular to said transverse direction.
- Such a metal profile can for example have an i-shaped section and can be anchored to the ground by dowels by being arranged parallel to the longitudinal direction. With this arrangement, the joint cannot undergo angular deformation around the transverse direction. A pendulum movement is thus authorized only on either side of the vertical plane to absorb variations in the length of the busbar, and maintenance of the circuit breaker is ensured along the longitudinal axis to resist the forces appearing when the circuit breaker is maneuver.
- the envelope is designed so as to have a certain flexibility. With this flexibility, the mechanical stresses in the enclosure are further reduced when the busbar expands.
- the envelope comprises several parts connected by connection zones, one or more of these connection zones may be flexible, being produced by extrusion and welding or by interposition of a hinged bellows.
- Figure 2 is a view along section A-A 'of Figure 1 of a metal profile
- the high-voltage shielded substation element partially shown in FIG. 1 comprises a high-voltage gas-insulated circuit breaker under a metal casing 1.
- the metal casing 1 contains a circuit breaker which extends along a horizontal longitudinal axis AX and is electrically and mechanically connected to a double set of bars 3, 4 extending in a direction D transverse to the axis AX.
- Such an envelope is generally assembled from several parts connected by connection zones. In the example of FIG.
- the metal casing 1 comprises a tank 1A surrounding the circuit breaker, with two taps 1 B (only one being shown) consisting of high-voltage connecting bars in a metal casing of tubular shape extending vertically from the upper part of the tank 1A, each tap having its upper end connected to a common point 1C which is itself connected to the busbars 3, 4.
- the common point 1C here comprises two not shown disconnectors which are intended to isolate electrically each busbar 3, 4 of the circuit breaker.
- the envelope may also include other electrical equipment not shown. The different parts of the envelope given in FIG. 1 are connected by connection zones 10, 10 'and 10 "which will be detailed below.
- the busbars 3 and 4 extend horizontally above the casing 1 which is held horizontally on the ground S by two metal frames 5 and 6 each resting on a shaped metal profile 7A, 7B from i.
- These metal frames 5 and 6 which each form a connection between a profile 7A, 7B and the casing 1 here form cradles to which the casing 1 is suspended by several attachment points.
- Other shapes with hooking points distributed differently can also be used without departing from the scope of the invention.
- the casing 1 of the station element extends along a longitudinal axis AX while the double set of bars 3, 4 extends along a transverse direction D which is perpendicular to the direction AX. When expanding, busbars 3 and 4 elongate along the direction D.
- each metal section having an i-shaped section such as the section 7A, is anchored to the ground S for example with pins 9 being positioned parallel to the longitudinal axis AX. It comprises a flexible vertical blade 8 which extends in a vertical plane P substantially perpendicular to the transverse direction D so that each profile 7A, 7B is capable of bending on either side of the vertical plane P.
- These profiles being arranged parallel to the longitudinal axis, the overall articulation thus produced prohibits any movement of the envelope in the vertical plane P.
- This arrangement makes it possible to maintain the envelope 1 of the station element along the longitudinal axis AX, and d 'thus preventing a longitudinal displacement of this item of station in the event of the circuit breaker being operated.
- the deflection angle ⁇ of the sections 7A, 7B on either side of the plane P is of the order of 100 th of radians.
- a slight pendulum movement of the envelope is therefore authorized thanks to the articulation function provided by the flexible element.
- the implementation of a hinge allowing a deflection angle of the order of 100 th of radian compensates for the expansion of a busbar of sixty meters long while in the prior art, it was necessary to mount axial bellows every twenty meters on such a busbar.
- Metal profiles are of course much less expensive to manufacture than axial bellows for busbars.
- the envelope 1 comprises three connection zones flexible 10, 10 'and 10 "respectively connecting the tank 1A to the nozzle 1 B, the nozzle 1 B to the common point 1 C and the common point 1C to the busbars 3, 4.
- the busbars 3 and 4 form with the taps 1 B of the casing 1 an angle ⁇ close to the right angle corresponding to a vertical position of the taps.
- the taps 1 B slightly tilt and form an angle ⁇ with the vertical, so that the angle ⁇ closes to take a value denoted ⁇ -i.
- This variation of the angle ⁇ is absorbed by the flexible connection zones 10 'and 10 "which decreases the mechanical stresses generated in the envelope by the dila tation of busbars 3 and 4.
- ⁇ ⁇ - ⁇ .
- connection zone 10 between the tank 1A and the tap 1B may be produced by extruding an opening in the tank to form a projecting flange on which a fixing flange will be welded or else the tap 1B directly.
- the choice of wrought aluminum and a radius of curvature suitable for extrusion makes it possible to adjust the flexibility of such a connection zone.
- a hinged bellows could for example be mounted at the level of the connection zone 10 'between the tap 1B and the common point 1C.
- Such a hinged bellows has a cost much lower than that of an axial bellows for busbars, which significantly reduces the cost of the armored station.
- Each element of the armored substation can be articulated on the ground and the elimination, thanks to the invention, of axial bellows on the busbars in the substation makes it possible to lower the cost thereof.
- the invention applies to other types of architecture of substation elements in a metallic envelope.
