Definitions

  • the present invention relates to a vacuum circuit breaker assembly and a switchgear assembly intended to be used in higher pressure environments such as sub sea and deep sea.
  • German patent publication DE 621 242 discloses an underwater switch assembly, in which a switch assembly is enclosed in a water tight dome. The switch assembly is operated in a regular manner using auxiliary switches outside of the water tight dome.
  • German patent application DE-A-102 38 950 discloses a vacuum switch, in which several elements form a sealed air tight enclosure. Inside the enclosure, a vacuum atmosphere is present.
  • European patent publication EP 0 466 048 discloses a switch gear for interrupting fault currents.
  • a vacuum circuit breaker and its associated actuating mechanism are combined in a single air tight enclosure.
  • One of the contacts of the circuit breaker is connected to a moving rod which penetrates the enclosure using a sliding bearing. This moving rod is used to re-arm the switch gear (connected state).
  • European patent application EP 0 293 323 A discloses a vacuum circuit breaker having an encapsulation of fibers and a thermal isolation layer, to make the vacuum circuit breaker weather and explosion resistant. It is noted that not the entire vacuum circuit breaker is encapsulated, to allow operation of the moving contact.
  • the present invention seeks to provide a vacuum circuit breaker assembly which is suitable to be used in under water or high pressure environment applications. Apart from the harsh environment, equipment at the bottom of the sea is also subjected to very high pressures up to several 100 bar.
  • One of the demands posed upon the switchgear under consideration is a long maintenance free life in a completely closed enclosure, suited for harsh environments. This implies that the most suitable switching technology is based on vacuum interrupters, the core of a vacuum circuit breaker. All other switching media, like oil, SF6 and air become polluted due to switching actions with a degradation of the switching medium as a result.
  • a solution is to be provided to protect the pressure sensitive bellows of a vacuum circuit breaker. Commercially and technically available vacuum circuit breakers are only suitable for use in environments with pressures up to a few bar.
  • a vacuum circuit breaker as defined by claim 1 is provided.
  • the housing further accommodates a drive mechanism, e.g. an electromechanical drive mechanism, for operating the vacuum circuit breaker.
  • the drive mechanism is arranged to be actuated using non-mechanical connections, e.g. using electrical, hydraulic or pneumatic signals.
  • the housing further comprises an additional feed through terminal in a further embodiment.
  • This feed through terminal may be provided as a through hole in one of the parts of the housing (e.g. a hole in one of the metal end caps, using an isolated and sealed off feed through, or a hole in the insulating tube).
  • the feed through terminal may be provided in a coaxial manner, when the housing comprises at least two isolating tubes, two terminals, and a conducting ring connecting two axially aligned isolating tubes.
  • Operation of the vacuum circuit breaker may be accomplished by wireless techniques, or in an alternative embodiment, using power line carrier techniques.
  • Alternative wired communication technologies e.g. optical fibers may also be applied by using a feed through.
  • the housing is arranged to maintain an internal pressure of substantially one bar (10 5 Pa) when the pressure outside the enclosure is higher than 1 x 10 5 Pa, e.g. higher than 100 x 10 5 Pa, e.g. 300 x 10 5 Pa.
  • This provides an environment of the vacuum circuit breaker which is comparable to the environment for which many vacuum circuit breakers are designed, i.e. a normal atmospheric pressure.
  • the housing may be filled with air, and the fluid tight and rigid housing will then be able to provide a 'normal' operating environment at least for the vacuum circuit breaker.
  • the housing comprises a tube, or cylinder, of isolating material, e.g. a ceramic material.
  • two terminals e.g. in the form of end caps
  • conducting material e.g. copper or aluminium
  • the two terminals are connected to terminals of the vacuum circuit breaker.
  • the housing is not limited to any specific form, and may be round, square, triangular, multi-facetted, etc. Such a vacuum circuit breaker assembly is easy and efficient to manufacture.
  • the housing may further accommodate an electronics module, which e.g. implements a network protection function and/or control and supply function of the electromechanical drive.
  • an electronics module which e.g. implements a network protection function and/or control and supply function of the electromechanical drive.
  • the housing further accommodates a current sensor, a voltage sensor, or a combination of a current sensor and voltage sensor.
  • a current sensor may be used for network protection functions and/or control functions of the vacuum circuit breaker.
  • the present invention relates to a switchgear assembly, comprising an external housing (or outer tube) and at least one vacuum circuit breaker assembly according to an embodiment of the present invention, in which the external housing has an inner space sealed from an external environment, the inner space comprising the at least one vacuum circuit breaker assembly, in which the inner space is filled with a substantially non-compressible material, such that, in operation, the pressure in the inner space is substantially equal to the pressure of the external environment.
  • the substantially non-compressible material may be a fluid, e.g. oil, or another substance, such as cast resin, silicone rubber, etc.
  • the non-compressible material is e.g. an insulating material.
  • the external housing may act as a pressure compensation arrangement, e.g. due to deformation of the external housing, the pressure inside is substantially the same as outside of the external housing.
  • the external housing is deformable, e.g. is the form of a stainless steel tube or a combination of a plurality of such tubes.
  • the external housing further accommodates a transformer for auxiliary supply at a service voltage level.
  • This transformer can be positioned e.g. between the associated busbars or connection and ground, to provide a (lower) voltage than the busbar voltage, e.g. for the electronics module in the vacuum circuit breaker assembly.
  • an auxiliary supply transformer may be positioned between two phases of the busbar system, which would allow to provide a (lower) supply voltage to the two associated vacuum circuit breaker assemblies using a single transformer.
  • the switchgear assembly further comprises a busbar system connected to the at least one vacuum circuit breaker assembly, in which the busbars and connections to the vacuum circuit breaker assemblies are also accommodated in the external housing.
  • the entire deep sea switchgear may be provided in a single external housing, alternatively, the housing may comprise a plurality of interconnected tubes, which together form the external housing.
  • the switchgear assembly further comprises a disconnector connected in series between one of the terminals of the vacuum circuit breaker assembly and an associated busbar, for isolating a faulty vacuum circuit breaker assembly from the busbar system.
  • the disconnector may be operable from the outside of the external housing, in a mechanical or remotely operated manner.
  • the disconnector may be of a simple type, and for isolating a faulty vacuum circuit breaker assembly a disconnector having a one time action is sufficient (e.g. operating with an explosive actuator).
  • Oil and LNG Liquefied Natural Gas
  • MV medium voltage
  • the vacuum interruption technology is based on the use of vacuum circuit breakers, which in general are equipped with a pressure sensitive bellows to allow movement of one contact (or both contacts).
  • Commercially and technically available vacuum circuit breakers are only suitable for use in environments with pressures up to several bar (10 5 Pa).
  • pressure compensation use is made of pressure compensation.
  • pressure compensation e.g., due to deformation of the enclosure the pressure inside the enclosure is kept the same as outside the enclosure.
  • the vacuum circuit breaker assembly 10 comprises a standard vacuum circuit breaker 15 which is positioned inside a housing 14. To be able to use the vacuum circuit breaker 15 inside a pressure compensated enclosure the vacuum circuit breaker 15 has to have its own little pressure proof housing 14 that shields the pressure sensitive bellows and keeps it around 1 bar (10 5 Pa).
  • a vacuum circuit breaker assembly 10 is provided comprising a housing 14 in which a vacuum circuit breaker 15 is accommodated, in which the housing 14 is air tight and arranged to maintain a pressure inside the housing which is lower than a pressure outside the housing. E.g.
  • the housing 14 is constructed in such a manner that it is possible to maintain an internal pressure of substantially one bar (10 5 Pa) when the pressure outside the housing 14 is higher than ten bar (10 x 10 5 Pa), or even higher than 100 bar (100 x 10 5 Pa), e.g. 300 bar (300 x 10 5 Pa).
  • the vacuum circuit breaker 15 is enclosed in a pressure proof housing of its own.
  • the pressure proof vacuum circuit breaker assembly 10 therefore has a number of further features.
  • the housing 14 has as little as possible moving penetrations, or even has no moving penetrations at all. As penetrations are weak spots of the housing 14, the number of penetrations is as low as possible. Furthermore, the housing 14 is as small as possible to make it economically attractive.
  • the housing 14 is formed by a tube 11 of isolating material (e.g. ceramic) and two end caps 12, 13 of conductive material (e.g. copper or aluminum).
  • the end caps 12, 13 are attached to the tube 11 in order to form a sealed housing 14, e.g. by welding the end caps 12, 13 to the tube 11.
  • One terminal 16 (e.g. a fixed terminal) of the vacuum circuit breaker 15 is (electrically) connected to end cap 12, and the other (moving) terminal is connected to the other end cap 13 (e.g. using a flexible wire 17), such that the end caps 12, 13 act as electrical terminals of the vacuum circuit breaker assembly 10.
  • a current sensor 17 may be added, which, in the embodiment of Fig. 1 is implemented as a ring shaped sensor around the moving terminal for the vacuum circuit breaker 15.
  • the current sensor 17 e.g. a current transformer or Rogowski coil
  • the current sensor 17 is in this embodiment located at the primary side of the vacuum circuit breaker 15, to be at approximately same potential as possible integrated protection and supply electronics (see below).
  • a drive mechanism 18, e.g. an electromechanical drive mechanism, is added, which operates on the moving terminal of the vacuum circuit breaker 15.
  • the vacuum circuit breaker 15 is operated by the drive mechanism 18, e.g. using an electromagnetic actuator (coil construction), which is a very compact, and maintenance free mechanism for a vacuum circuit breaker 15.
  • an electronics module 19 e.g. in the form of a printed circuit board, may be added, which may be arranged to perform various functions. These functions are e.g. protection circuitry, supply for the drive mechanism 18, communication/control interface, etc.
  • the embodiment shown in Fig. 1 is also provided with a feed through hole 21, which allows to provide an external connection 22, e.g. for routing a control signal for the vacuum circuit breaker 15 to the electronic module 19, or for inputting an auxiliary voltage supply.
  • the feed through hole 21 may be implemented as a penetration in the end cap 13 as shown, but may also be provided in the other end cap 12, or in the tube 11.
  • the sealed housing 14 is sealed at the position of the feed through terminal 21.
  • glass or other pressure resistant insulating material can be welded in a pressure proof construction.
  • a further embodiment is shown schematically in a perspective view.
  • the housing 14 is formed by two tube parts 11a, 11b, two end caps 12, 13 and a coaxial ring 22a of conductive material.
  • the various parts are connected to each other, e.g. using welding techniques, to form the sealed housing 14.
  • the ring 22a may then be used as feed through terminal.
  • Fig. 2 is also provided with additional medium voltage terminations 12a, 13a. These terminations may be separate elements, or integrally formed in the end caps 12, 13.
  • this terminal in the form of external connection 22 or additional conducting ring 22a can be kept very small.
  • the power supply of the electronics module 19 (electronic protection and EM drive) is connected to the mains at one side (connected internally to end cap 13, thus no extra penetration) and to the external connector 22 at the other side.
  • This external connector 22 may be connected to an external transformer 29 (see below), providing a low voltage level (e.g. 100 V) with respect to the main terminal (end cap 13).
  • the electronic protection and control function provided by the electronics module 19 acts autonomously it also has to communicate for remote on/off commands, etc.
  • this embodiment uses either wireless or Power Line Carrier technology. Both technologies have the advantage that no extra penetrations are necessary through the housing 14, thereby increasing reliability and decreasing costs.
  • non-moving parts which penetrate the housing 14 of the vacuum circuit breaker assembly 10
  • the non-moving parts may e.g. comprise an electrical or optical connection as described with reference to the embodiments of Fig. 1 and 2 above, but also other actuating signals which require no moving parts may be used, such as hydraulic or pneumatic signals.
  • These signals may be transferred to the circuit breaker assembly 10 using suitable piping or tubing, which may then penetrate the housing 14 in a similar non-moving manner as the (electrical/optical) external connection 22 and feed through hole 21.
  • the pressure proof vacuum circuit breaker assemblies 10 as described relating to the various embodiments above can be used in a number of construction principles, a first one of which is shown schematically in Fig. 3 .
  • the pressure proof vacuum circuit breaker assemblies 10, a busbar system 26 and other assembly components are enclosed by a pressure compensated enclosure, formed by a number of tubes like enclosures 25, 35 (i.e. a number of vacuum circuit breaker compartments 25 and a busbar compartment 35, connected to each other).
  • the enclosures 25, 35 e.g. made as stainless steel tubes, are filled with an insulating, virtually non-compressible fluid like oil.
  • Advantage of this fluid filled enclosure 25, 35 is that a small deformation of the enclosure 25, 35 is sufficient for a huge rise in internal pressure. A small deformation is important to keep the mechanical stresses in the enclosure material low.
  • Second advantage of the insulating fluid is the good insulating properties that enable a compact and economic design.
  • the outer walls of the enclosures 25, 35 are resistant to the harsh environments, that might be present at the bottom of the sea (depth from 0 to several km). Generally a metallic layer or wall is foreseen, intended to be grounded if necessary.
  • the main busbar system 26 can be either single-phase or multiphase. No moving components are foreseen in the main busbar compartment 35, to have maximum reliability and therefore maximum availability.
  • the pressure compensated enclosures for the switching might be single phase to allow for maximum (rotational) symmetry.
  • multiphase design allows for integrated voltage transformers between phases as auxiliary voltage supply, as shown e.g. in Fig. 4 .
  • a voltage transformer 29 is connected between two phases X, Y of a three phase busbar system 26, allowing to supply a lower auxiliary voltage level (U aux,x , U aux,y ) to both the X-phase vacuum circuit breaker assembly 10 and the Y-phase vacuum circuit breaker assembly 10.
  • cable terminals 27 are provided, which are internally connected to the vacuum circuit breaker assemblies 10, e.g. to the medium voltage terminations 12a as shown in Fig. 2 .
  • Each of the vacuum circuit breaker compartments 25 is provided with a pressure relief 36, which is constructed in such a manner that in case of an internal arc in a vacuum circuit breaker compartment 25, none of the other elements in the switchgear assembly or other elements, such as connected cables, are affected.
  • FIG. 5 the internal components in an enclosure 25 as discussed above in relation to the embodiment of Fig. 3 are shown.
  • the external environment e.g. sea water at 300 bar pressure.
  • oil is present, and the material of the enclosure 25 allows this oil to be at the same pressure, i.e. also 300 bar.
  • Three vacuum circuit breaker assemblies 10 are located inside the enclosure 25, which allow to close or open the circuit connected to the external cable connectors 27.
  • a busbar connector assembly 28 provides for connecting the vacuum circuit breaker assemblies 10 to each phase of a busbar system 26 (see Fig. 3 ).
  • the busbar connector assembly 28 also acts as a pressure proof shielding, in order to protect the busbar compartment 35 from a rise in pressure in one of the vacuum circuit breaker compartments 25, e.g. as a result of an internal fault.
  • transformer 29 of the embodiment in Fig. 4 in this embodiment a separate transformer 29 is present, connected between the respective phase and the (grounded) enclosure 25.
  • Each transformer 29 provides the supply voltage via a feed through hole 21.
  • disconnectors 32 allow to isolate a vacuum circuit breaker assembly 10 from the busbar system 26, e.g. in the case of a faulty vacuum circuit breaker 15 (short circuit).
  • the disconnector 32 may be any form, e.g. remotely operable, or (mechanically) operable from the location of the switch gear using a remotely operated vehicle (ROV).
  • ROV remotely operated vehicle
  • the disconnector 32 may be in the form of a normally closed switch, which can be opened a single time (e.g. using an explosive charge) or multiple times. This embodiment is particularly useful to increase the reliability of the switch gear system, e.g.
  • a spare vacuum circuit breaker assembly 10 is provided as shown schematically in Fig. 6 .
  • an enclosure 25 is provided around a single phase busbar system 26, as well as two vacuum circuit breaker assemblies 10, in further enclosures 25.
  • two disconnectors 32 are provided, of which one is closed, and one is opened.
  • the associated disconnector 32 should be opened, thereby isolating the faulty circuit breaker assembly from the busbar and allowing the remaining switchgear assembly to return to normal service conditions.
  • the vacuum circuit breaker assemblies 10, busbar system 26 and other assembly components are moulded into a solid insulation material (e.g. cast resin, silicone rubber).
  • a solid insulation material e.g. cast resin, silicone rubber.
  • the construction does not contain any compressible gas filled chambers.
  • the lack of compressible chambers makes it possible to use a relatively thin layer of insulation material.
  • This thin layer of insulating material is designed mainly on isolating (dielectric) aspects instead of mechanical aspects dealing with the high pressure of the surrounding water.
  • a single phase construction has the preference due to the simplicity of moulding compared to the moulding of a three phase construction.
  • the solid insulation is constructed to bear part of the mechanical stresses on the vacuum circuit breaker assemblies 10. As further mechanical structure is then not needed, this embodiment results in a lower total weight.
