Definitions
- the invention relates to an electrical power resistor which is typically used in electrical generators and frequency converters.
- a power resistor is used to convert electrical energy into thermal energy in special operating states in electrical systems in which the electrical energy present must typically be significantly reduced in periods of a few milliseconds to a few seconds. This is the case, for example, in wind and hydroelectric plants.
- Such a power resistor may be formed by a stack of a plurality of metal resistance plates, each resistance plate of the stack having at least one meandering structure formed by a plurality of successive mutually interconnected transverse webs.
- a resistance unit is created, which can be easily adapted to the respective application with a simple structure.
- the individual resistance plates must therefore be used in a stable holder or other fastening device which receives the described repulsion and expansion forces and gives the resistance unit formed the necessary mechanical stability.
- a holder or other fastening device must prevent the end regions of the respective resistance plate from being torn off and ensure a sufficient dimensional stability of the resistance unit with regard to an attachment of the power resistor to another structure (eg in a control cabinet).
- the power resistor comprises a stack of at least two resistance plates, which are arranged one above the other along the stacking direction, in particular parallel to each other and spaced from each other.
- the orientation of each second resistor plate is relative to the orientation the previous resistance plate of the stack rotated by 90 ° in the respective plane of the plate, and with respect to the respective direction of extension of the meandering structure (ie longitudinal direction). This means that the repulsion and expansion forces occurring perpendicular to the orientation of the transverse webs of the respective resistance plate from resistance plate to resistance plate are likewise rotated by 90 ° with respect to one another.
- all resistance plates of the stack are fastened to each other by means of a common fastening device.
- a fastening device may have a simple and inexpensive construction, since it is mainly necessary to achieve that the longitudinal expansion forces of the one resistance plate are transmitted to the adjacent or adjacent (twisted by 90 °) resistance plate or resistance plates. Due to the inherent stability of the resistance plates in the transverse direction, ie along the direction of extension of the transverse webs of the respective meandering structure, forces in this direction can be absorbed by a resistance plate without requiring special requirements for the fastening device.
- the resistance plates are quadrangular, with pointed or rounded corners.
- the resistance plates are rectangular, in particular square, wherein in the case of unequal side lengths, the longer side length does not necessarily define the aforementioned longitudinal direction (which is determined solely by the extension direction of the meandering structure of the resistance plate).
- a fastening opening is provided for receiving a respective fastening element.
- the attachment openings of the various resistance plates are arranged in alignment with each other.
- common fasteners can be used, which are performed by the flush mounting holes.
- the resistance plates of the stack may be fastened to each other via attachment rods which are guided through the attachment openings of the resistance plates.
- the mounting rods may be threaded rods or screws.
- a self-supporting structure of the stack is formed in a simple manner, without an external support, for example in the form of a cage, for mutually securing the resistance plates is required.
- said fastening elements, in particular the said attachment rods are electrically insulated from the resistance plates. This can be done for example by plugged mica tubes.
- the arrangement of said fastening openings and fastening elements with respect to a rotation of the respective resistance plate is 90 ° rotationally symmetrical.
- the attachment openings of one resistance plate are aligned with the attachment openings of another, adjacent thereto resistance plate, even if said one resistance plate is rotated by 90 ° relative to the other resistance plate.
- the power resistor can be reconfigured even easier for other applications, since the resistance plates can be combined with each other in a particularly flexible manner, and the resistance plates can be designed as a common part.
- connection means for electrically contacting the resistance plate.
- This connection means can be designed, for example, as an opening (for example a hole) or as an inserted, attached and / or welded-on bolt. If several or all resistor plates of the stack are provided with the same connection means, the adaptation of the power resistor to a desired resistance value can be carried out in a particularly flexible way. For example, each resistance plate at the two ends of the meander-shaped structure have a connection means for electrical contacting.
- At least one of the resistance plates has at least one respective connection means for fixing an insulator.
- the connecting means may be, for example, openings, screws or bolts.
- the insulators attached to the respective resistor plate allow arranging and attaching the power resistor to another structure, for example in a control cabinet.
- connection means and connection means three groups of different mechanical and / or electrical means are available which can be easily introduced by means of the same tool (for example, in the case of holes).
- two successive resistance plates in the stacking direction are separated from one another by respective spacers, wherein the spacers may optionally be designed to be electrically insulating or electrically conductive.
- the spacers cause a predetermined distance of the preferably plane-parallel arranged resistance plates relative to each other.
- a respective intermediate space between two adjacent resistance plates is formed in the stacking direction, which can be used in particular for cooling purposes (air cooling or liquid cooling).
- air cooling or liquid cooling By using separate spacers, the respective spacing between two adjacent resistance plates can be flexibly adjusted depending on the desired application.
- the spacers may be formed by sleeves, which allow a particularly good air circulation between the resistance plates and thus a good heat transfer to the ambient air.
- continuous spacers may be provided, for example in the form of webs or plates.
- electrically insulating materials are ceramics, mica, rubber, silicone or plastic.
- the resistance plates preferably have a respective end connection web (so-called terminal), which is formed wider than the transverse webs of the meandering structure.
- the already mentioned fastening openings for the fastening device can be provided on the particularly stable end connection webs in order to be able to reliably absorb the explained expansion forces of the respective adjacent resistance plate.
- the said attachment openings can also be provided on the transverse webs.
- the resistance plates in a respective middle region can have at least one center connection web, which is also wider than the transverse webs.
- the meander-shaped structure of the respective resistance plate which forms the active region of the electrical resistance, is subdivided into a plurality of segments. These segments may be shaped the same or different, and they may have the same or different electrical resistance.
- Such a middle connection web also contributes to increasing the mechanical stability in the transverse direction.
- further attachment openings are preferably provided for receiving a respective fastening element, in addition to the attachment openings on the end connection webs.
- at least one connection means for electrical contacting is provided on the respective center connection web (eg opening or bolt).
- the transverse webs of the meander-shaped structure of a respective resistance plate are electrically insulated from one another along the intermediate spaces formed between two adjacent transverse webs, either only in sections or over the full length of the respective intermediate space.
- unwanted arc ignition can be prevented.
- the deformation of the individual transverse webs can be so strong that adjacent webs adjacent to one another touch each other or almost contact each other at least for a short time. This effect can ignite an arc that could damage or destroy the power resistor or associated electrical equipment.
- the mutual electrical insulation of the transverse webs can be accomplished in particular by insulating strips (ie electrically insulating strip-shaped plates) which are inserted into the interspaces between two adjacent transverse webs and in particular consist of ceramic, mica or plastic, for example polybenzimidazole (PBI).
- insulating strips ie electrically insulating strip-shaped plates
- PBI polybenzimidazole
- insulating strips and granules or other filler can be pressed into the spaces between two adjacent transverse webs, for example, heated polybenzimidazole.
- a sufficiently cured liquid insulating material can be used, which by filling, injecting or foaming the spaces between two adjacent transverse webs completely or partially fills, for example, silicone, cement or concrete.
- a sufficiently hardened liquid insulating material may be used, which covers the transverse webs as a coating, for example in the form of a thin polybenzimidazole film, which forms a protection against moisture in addition to the electrical insulation (corrosion protection).
- a particularly simple and cost-effective production of the individual resistance plates results when the meander-shaped structure of each resistance plate is formed by mutual incisions, which are preferably offset from one another.
- the cuts between adjacent transverse webs can be introduced for example by means of a laser beam, high-pressure water jet, a saw or a milling cutter, in particular in the same operation, in which the respective resistance plate is cut out of a larger plate.
- all the resistive plates of the stack, or all of the resistive plates of the stack, with the exception of a base plate, are made identical to each other, i. as equal parts. This results in a particularly cost-effective production and storage, and the respective power resistance can be configured in a flexible manner.

- the transverse webs 15 extend over the full side length of the respective resistance plate 1 1, 12, 13.
- the resistance plates 11, 12, 13 may also comprise a plurality of meander-shaped structures which run next to one another.
- Each resistance plate 11, 12, 13 has at the two ends of the meander-shaped structure a respective end connection web 21, which is wider than the transverse webs 15. Furthermore, each resistance plate 11, 12, 13 has a center connection web in a middle region 23, which is also wider than the transverse webs 15. The center connecting web 23 divides the meandering structure of the respective resistance plate 1 1, 12, 13 in two active areas 25th

- a common attachment device which comprises a plurality of fastening elements 33 common to the three resistance plates 11, 12, 13.
- only six fasteners 33 are provided, i. three mounting holes 31 of the respective resistance plates 1 1, 12, 13 remain unused.
- the fasteners 33 are formed in the embodiment shown here as hexagon screws, which cooperate with hex nuts 35 to hold the stack of resistance plates 1 1, 12, 13 together.
- spacers ensure that the resistance plates 11, 12, 13 are arranged at a distance from each other.

- FIG. 5 shows a detailed view of the power resistor according to FIG. 1 in cross section. It can be seen that the fastening element 33, ie the hexagonal screw, is surrounded by a mica tube 51, which likewise penetrates the fastening openings 31 of the resistance plates 11, 12, 13 and thus electrically isolates the hexagonal screw from the resistance plates 11, 12, 13.
- the fastening element 33 ie the hexagonal screw
- the power resistor shown in Figs. 1 to 5 has a simple structure and can be produced in a cost effective manner.

- the power resistor can be flexibly adapted to different requirements, for example, by changing the number of resistance plates 11, 12, 13 of the stack, or alternatively, by changing the arrangement of the electrically insulating spacers 37 and the electrically conductive spacers 39, a series circuit or a parallel circuit is realized.
- the power resistor can be used as a voltage divider by means of the middle connection web 23 of the respective resistor plate 11, 12, 13. If the voltage drop across the power resistor or parts of the power resistor is measured, the power resistor can be used as a current sensor.
- the resistance value of the power resistor can be easily adjusted by means of an electrically conductive bridge connecting, for example, two transverse webs 15 across a gap 17 (e.g., by clamping or welding).
- the said expansion forces therefore do not have to be absorbed by an outer supporting structure, and it is only necessary to ensure that the fastening elements 33 (eg hexagon screws) are dimensioned sufficiently strongly.
- a non-rotationally symmetrical arrangement of the attachment openings 31 may be provided to thereby realize directional coding and to ensure that the individual resistance plates 11, 12, 13 can be mounted relative to each other only in a single predetermined orientation. This can thus be ensured in a simple manner that the 90 ° to each other twisted orientation of the respective Extension direction of the meander-shaped structure of adjacent resistance plates 1 1, 12, 13 is always maintained.
- intermediate spaces 17 between adjacent transverse webs 15 can also be completely or partially filled with an electrically insulating material.
- This filling material can serve as a spacer between adjacent transverse webs 15 and reliably prevent unwanted ignition of arcs that could arise if adjacent transverse webs 15 are too close due to magnetic interaction, thermal effects and / or external vibrations.
