Definitions
- the present invention relates to an electrical resistance structure. More particularly, the invention relates to such an electrical resistance structure comprising: an electrical resistor forming a folded boustrophedon ribbon so that the ribbon comprises rectilinear sections extending in a longitudinal direction of the electrical resistance, and curved sections U-shaped having two branches, the two branches being spaced from each other by a distance D1, - a frame comprising sleepers, and
- the fixing means being fixed on two opposite crosspieces, the fixing means comprising spacers provided with spaced projections and defining between them receiving zones of at least a portion of the curved sections, by clamping and with a game in said longitudinal direction.
- the fastening means used up to now hardly absorb the variations in length of the branches related to the temperature variations of the resistive element.
- the subject of the invention is a structure of the aforementioned type, each branch of each curved section comprising a zone formed in such a way that the difference D2 between the zones formed by two branches of the same curved section is reduced. relative to the difference D1 between said main faces of said two branches, said formed zone being formed without cutting or welding, said formed areas being adapted to engage between the projections of the spacers.
- the projections of the spacers are formed by studs; the spacers are fixed on the crosspieces by screw-nut systems; and
- the spacers are made of ceramic.
- FIG. 1 represents a perspective view of an electrical resistance structure according to the invention
- FIGS. 2 and 3 show detail views of this structure
- FIG. 4 shows a perspective view of spacer means forming part of the constitution of such a structure.
- an electrical resistance structure 1 which comprises a frame 2 for receiving electrical resistance means 3.
- the frame is for example formed of two columns designated by the general references 4a and 4b at the ends of which are provided respectively cross 5 and 6.
- the frame also comprises conventionally, for example in each corner, fixing means such as 7 on any adjacent structure.
- the electrical resistance means 3 are in the form of a resistive ribbon folded in the form of boustrophedon.
- the ribbon comprises rectilinear sections 18 extending in a longitudinal direction of the electrical resistance 3, and curved sections 19.
- the rectilinear sections 18 are parallel to each other.
- Each curved section 19 is disposed between two rectilinear sections 18.
- Each curved section 19 has a U-shape having two branches 20, 21 whose main faces are separated from each other by a distance D1.
- the curved sections 19 are associated with fastening means 8, 9 on the opposite crosspieces 5 and 6 of the frame.
- the resistance is made in one piece without welding.
- the two terminal ends of the resistive element have connection terminals respectively 10 and 11 to the rest of the electrical circuits.
- the invention relates to a particular structure which implements fastening means 8, 9 adapted to allow absorption of the variations in length of the resistive element consecutive to temperature variations thereof. .
- these fastening means 8, 9 comprise, as can be seen more clearly in FIGS. 2, 3 and 4, spacer means, for example in the form of bricks 12.
- these means forming a spacer or brick 12 comprise a base 13 making it possible to secure it to the corresponding crossmember of the frame via, for example, holes and screw-nut means 22.
- This base is provided with protruding parts or pads 14, which are regularly distributed on the spacer means for defining between them zones 24 for receiving portions of the curved sections 19 of the resistive element by clamping and with longitudinal play.
- the two branches 20, 21 of each curved section comprise a zone formed so that the gap D2 between two zones formed of a curved section is reduced compared to the difference D1 between the two main faces of the two branches 20, 21 of the same curved section.
- Said zones formed by two branches of a curved section 19 are adapted to engage between the projections 14 of the spacers on either side of the reception zone.
- Guiding wings 16 and 17 are formed on either side of the formed zone 15. The guide wings 16 and 17 extend on either side of the spacer means.
- Such a structure thus makes it possible to receive the resistance in the frame with the possibility of absorbing variations in the length of the branches of the resistive element.
- Such a structure is made without cutting or welding, to avoid any local concentration of current.
- the spacer means may be made of ceramic or other so as to provide electrical insulation of the resistive portion.
