Definitions
- the invention relates to a load switch according to the preamble of claim 1.
- Such load switches see for example DE-U-93 14 754 - are e.g. as switch disconnector known in rail operations.
- the Vacuum interrupter in the on position with the in switching mechanism housed in an insulating housing electrically shunted to that for the full device current designed main current path.
- the vacuum interrupter When switching off first open the main contacts without power and commutate the current to the one in the shunt Series connection of vacuum interrupter and Auxiliary switching point, which has an operating fork. Once the main contacts are far enough apart the vacuum interrupter is removed a tilting mechanism is quickly activated and that inside the switching chamber Arcing occurs in the first Current zero crossing safely extinguished without external appearance.
- Vacuum interrupters or chambers used relatively have large dimensions and high manufacturing costs are connected. Therefore, for some time now Vacuum interrupters of a lower voltage range, than that for which the switch is designed. This allows both the dimensions as well the manufacturing costs are reduced, the Active part in the vacuum interrupter such Use generally permitted.
- the vacuum interrupters are placed in a medium with higher dielectric strength.
- Insulating oil such as mineral or silicone oil, various esters or an insulating gas such as sulfur hexafluoride (SF 6 ) are used. These media displace the air in the vicinity of the vacuum interrupters and because they have a high dielectric strength, an external flashover is prevented.
- SF 6 sulfur hexafluoride
- Document FR-2 698 481 A1 discloses a load switch with a vacuum interrupter, being between the housing of the vacuum interrupter and an electrically insulating silicone body is disposed on an outer case is.
- This silicone body is tubular and either faces the On the outside or on the inside elastically deformable ribs. He is like that procure that he at the same time an intimate contact to the outer surface of the Interrupter housing and inner surface of the outer housing. Thereby should be a gap-free to avoid an electrical flashover be achieved.
- an insulating grease be introduced while the ribs are on the outside for manufacturing a seal can be compressed at least to a small extent.
- the German utility model G 93 14 754 Ul discloses a vacuum interrupter with one against internal pressure durable encapsulation.
- the encapsulation of this vacuum interrupter consists of an inner layer hard plastic foam and an outer burstproof Coat.
- the preferably from one Polyurethane foam is inner layer evenly porous to according to the teaching of this document to enable the best possible thermal insulation, so in the event of a fault none to ignite the surrounding one Gases sufficient temperature can be reached.
- the Burst-proof sheath is designed as a winding body and consists of threads or tapes that are cured with a Plastic are soaked. It is close-fitting formed on the foam layer and so dimensioned so that it can absorb the bursting force, which at an error occurs within the vacuum interrupter.
- the casing of the tube also contains this State of the art a firmly foamed plastic material, which due to aging in its properties can be affected. In particular, embrittlement or a detachment of the foam layer from the Outer casing of the tube occur. It is also one Disassembly of this encapsulated vacuum interrupter only at destruction of the casing possible.
- the invention is therefore based on the object to create a load switch that is out of control Can be used safely for a long time and can also be dismantled is.
- the main advantage here is that due to there is no gap in the elastic properties of the cuff remains on the periphery of the housing. A rollover to the vacuum interrupter via such Air gap is therefore not possible.
- the load switch according to the invention has numerous others Advantages on.
- the load switch can therefore last for many years be used in continuous operation without the as dielectric medium-acting sleeve checked must become.
- the load switch according to the invention e.g. also in water protection areas can be used without hesitation.
- a permanent load switch is provided, that can be used universally.
- Another advantage is that the assembly of the circuit breaker according to the invention essential simplified. So training with a prefabricated cuff a pre-assembly of the arrangement, which is why no effort for a final assembly or a filling e.g. high up on the mast. There not handling any liquid or gaseous medium the transport effort is simplified and the installation of the circuit breaker according to the invention essential.
- the circuit breaker according to the invention is simple to manufacture and allow disassembly if necessary. In addition, the space requirement and the costs for the vacuum interrupter can be kept low.
- a complementary pressure housing Is made of insulating material, which the outer circumference of the cuff in the elastic range.
- this ensures that the cuff presses firmly against the vacuum interrupter and further that no on the outer circumference of the cuff Air gap arises, which allow an external rollover could.
- the possible distance for a rollover is thereby enlarged to a level at which this is practically no longer possible. Operational security and reliability of the circuit breaker thereby further increased.
- the vacuum interrupter thereby centered and fixed in the pressure housing.
- the dimensions of the cuff are chosen are that the cuff is preloaded on the Vacuum interrupter is reliably prevented, that there is an air gap between the cuff and the housing of the vacuum interrupter. In order to can also the relatively large dimensional tolerances of the Vacuum interrupter can be compensated. So increases the reliability of the circuit breaker.
- the cuff at least one in the axial direction of the pressure housing extending sealing bead, the comes to rest in the assembly joint of the pressure housing, is also a seal against the pressure housing external influences reached. This makes it reliable avoided that e.g. Dirt and especially water in the pressure housing can penetrate. Failure of the load switch can thus be avoided effectively. Also relieved the one-piece design of the cuff with assembly of the arrangement.
- the sealing bead also has a thickening, the can be squeezed in the assembly joint of the pressure housing, the reliability of this seal increases Pressure housing further.
- the cuff at least one recess for receiving at Compressed material of the cuff displaced. It is achieved that the cuff fits neatly on the peripheral surface of the vacuum interrupter, without damaging the cuff the applied pressure forces occur. The reliability the load switch increases further.
- the at least one recess is advantageously as a circumferential ring groove in the inner periphery the cuff. This will make it even Pressure distribution over the entire circumference of the vacuum interrupter reached.
- the length of the vacuum interrupter can be adjusted, without damaging the material of the cuff as it will dodge into the at least one pocket can.
- the reliability of the cuff and thus the Operational reliability of the circuit breaker is thus increased.
- the at least one pocket is also ring-shaped, becomes an even distribution of pressure load reached on the front of the cuff.
- the cuff according to the invention is preferably made of EPDM (ethylene propylene terpolymer) or silicone rubber manufactured which have good elastic properties have and are not compressible.
- EPDM ethylene propylene terpolymer
- silicone rubber manufactured which have good elastic properties have and are not compressible.
- the load switch as a load break switch is formed in the series connection to the vacuum interrupter arranged a visible separation distance can be visual even from a distance Control to determine whether the Load switch is closed.
- a Load switch 1 is a pressure housing with two housing halves 11 and 12, which are made of insulating material and essentially are mirror images.
- halves 11 and 12 include a vacuum interrupter 2 and a switching mechanism 3 arranged.
- the way of arrangement and function of the vacuum interrupter 2 and Switch mechanism 3 corresponds to the known designs, which is why there is no detailed explanation becomes. It is essential that the vacuum interrupter 2 inside switching contacts, which by the Switching mechanism 3 can be closed or opened.
- the vacuum interrupter 2 has in addition to the movable Contact 21 a fixed contact 22 on the arranged opposite the movable contact 21 is.
- the vacuum interrupter 2 also has a housing 23 on that with metal end plates 24 and 25 is provided, which has a cylindrical housing middle part Complete 26.
- the middle housing part 26 is made of electrically insulating material.
- EPDM ethylene-propylene terpolymer
- the cuff 4 is there trained so that the edges of the two End plates 24 and 25 of the vacuum interrupter 2 engages.
- the dimensions of the cuff 4 are so chosen that tolerance deviations of the vacuum interrupter 2 can be compensated and the cuff 4 nevertheless under tension on the peripheral surface of the vacuum interrupter 2 is present. As a result, there is no continuous Air gap between the face plates 24 and 25 in front.
- the cuff 4 is in turn from the housing halves 11 and 12 of the load switch 1 gripped and biased. Due to the preload is also between the sleeve 4 and the assembled housing halves 11 and 12 no air gap in front of it that would roll over the tension between the end plates 24 and 25 of the Vacuum interrupter 2 would allow.
- the cuff has 4 ring-shaped screens 41, which in corresponding recesses in the housing halves 11 and 12 are included.
- the screens 41 are used in a known manner Way to extend the path (Creepage distance) along the surface.
- the cuff 4 also has four cutouts 42 which are arranged on the inner peripheral surface and have an annular shape. While closing the housing halves 11 and 12 is pressure on the cuff 4 exercised and since this is made of an elastomer material is produced, which is elastic but essentially the cutouts allow not compressible 42 evading the material of the cuff 4 into the free spaces thus created. On this will damage the cuff 4 prevents and a good seal of the interface between the sleeve 4 and the vacuum interrupter 2 reached.
- annular pocket 43 is also formed.
- Vacuum interrupters 2 relatively large length tolerances may have a length setting or positioning of the vacuum interrupter 2 in the load switch 1 necessary. The necessary deformation the cuff 4 in this end region enable, the annular pocket 43 serves as a chamber for volume compensation of the displaced material.
- the cuff has 4 also a sealing bead 44 with a thickening 45 on. These are each on the two assembly joints Housing halves 11 and 12 of the load switch 1 for sealing arranged against external influences.
- the Thickening 45 is in appropriately trained Indentations or grooves on the joint surfaces of the housing halves 11 and 12 added and when closing the Housing halves 11 and 12 squeezed.
- the sealing bead 44 with the thickening 45 has a length that corresponds essentially to the total length of the cuff 4. But it can also be used in the entire assembly joint area the housing halves 11 and 12 in one piece with the Cuff 4 as a round cord for sealing the pressure housing be trained.
- the load switch used as switch disconnector and in series with one visible separation distance arranged.
- One is for the main current path designed in parallel to the vacuum interrupter and one with this in Series connected auxiliary switching point, whereby the vacuum tube with the switch disconnector switched on is relieved.
- To switch off the load break switch the main contact is first opened in a known manner, whereby the voltage is completely across the vacuum interrupter 2 is directed. Then be the contacts 21 and 22 of the vacuum interrupter 2 separated and the connection is completely broken, without arcing in the circuit breaker 1 can train.
- the dimensions and shape of the cuff 4 can vary depending on the design and type of the vacuum interrupter 2. It is essential in any case that the Sleeve 4 rests against the vacuum interrupter 2 in such a way that no air gap between them is possible.
- the cuff 4 does not have to be formed with screens 41 but can also be a different one or have a smooth outer peripheral surface, if the Safety of the load switch 1 e.g. due to minor existing voltages.
- the recesses 42 in the cuff 4 have shown example semicircular cross sections and are in four places around the vacuum interrupter 2 educated. Both the shape and the number of annular recesses 42 can deviate from this. Furthermore, it is also possible to use the cutouts 42 instead the shown embodiment with an annular Shape at points on the inner circumferential surface to provide the cuff 4.
- the pocket 43 in the cuff 4 can also be on both End faces may be provided. Furthermore, can also the shape and number of pocket 43 in a similar manner Vary as in the recesses 42.
- the cuff 4 can be connected in any way can be used with vacuum interrupters 2 which also have switching elements other than switch disconnectors includes. It is also used in circuit breakers and the like conceivable.
- the pressure housing can also consist of more than two housing parts exist, the number of sealing beads 44th is adapted to the number of assembly joints.
- the invention thus creates a load switch 1 for voltages in the kV range with a vacuum interrupter 2, which with a made of elastomer material high dielectric strength sleeve 4 is gripped without gaps.
- the cuff 4 is in turn through the housing halves 11 and 12 of the Load switch 1 clamped.
