Definitions

  • the invention relates to a hydraulic device according to the preamble of claim 1.
  • Such a hydraulic device is used in particular to actuate the movable contact pieces of a high-voltage circuit breaker, high voltage also being understood to mean the medium-voltage range.
  • a circuit breaker can be designed as a gas-insulated, in particular SF 6 -insulated, as a metal-enclosed switch or as an outdoor switch.
  • the drives for actuating each circuit breaker or the movable contact piece in each case one pole or several poles of the circuit breaker have an energy store which can be designed as a spring accumulator, the energy of which is released for actuating the movable contact piece.
  • the energy store is integrated in a hydraulic device, and the movable contact (s) are each connected to a working piston.
  • the hydraulic energy is supplied on both sides to the working piston both in the room with the larger area and in the room with the smaller area, so that the piston is moved in a switching position.
  • actuating a suitable changeover valve the space, which is limited by the larger piston area, is connected to a low-pressure container, as a result of which the piston can suddenly move and move the movable contact piece into the switched-off position.
  • Such a device is known from FR-A 2 685 541.
  • a block with a valve is provided which is connected to a piping system
  • High pressure fluid to the main valve controls, being between the block and the main valve Pipelines are provided, the arrangement with respect to assembly comparatively make it complicated.
  • the object of the invention is to provide a hydraulic device of the type mentioned create, which is considerably simplified compared to the known device.
  • the central distribution device is in the form of a distribution rail formed, which has a rectangular cross section and is elongated; the Lines for high pressure and low pressure hydraulic fluid are formed by two parallel longitudinal bores within the distribution rail.
  • the distribution rail has a further advantage that it is used at the same time be able to hold the individual components.
  • the distributor rail is not only used to distribute the hydraulic fluid, but also to hold the individual components, so that the individual components together with the busbar a preassembled unit form.
  • hydraulic device according to the invention on a metal-encapsulated, gas-insulated Switchgear is flange-mounted, then there is the piston-cylinder arrangement between the distribution rail and the flange; the control valves are on the Flange-side side surface of the distribution rail attached.
  • a further simplification of the invention can be that the individual components modular design and on the distribution rail with the interposition of a The same seal for all connections to the high-pressure and low-pressure lines leading connecting lines are attached. This allows assembly and warehousing be simplified considerably.
  • the storage space of the Energy or high pressure storage directly on the distribution rail adjoin, with that of the larger piston area opposite end wall of the storage space through the adjoining side wall of the distribution rail is formed. So that the assembly at this point as well as the seal is simplified, the high-pressure accumulator has one Collar that goes into a recess in the side wall Interposition of a seal engages.
  • the distribution rail can preferably be made of aluminum consist. This gives it sufficient strength relatively light weight.
  • the distribution rail can be prepared with an extruded profile and be longitudinal bores, so that only the cross holes for further processing with the associated seals and other connections are to be produced.
  • Adjustment slides are introduced with which the river of the hydraulic fluid within the longitudinal or transverse bores an adjustable resistance can be opposed can, so that on the one hand the movement of the working piston set and on the other hand also bumps within of the pressure fluid can be reduced or damped.
  • a housing 11 is attached, in which a hydraulic device for actuation the circuit breaker is arranged.
  • the flange plate 10 has openings 16 (of which in Figure 2 only one opening is visible) through which one Drive linkage 17 passes through, which with the respective movable contact pieces of the individual circuit breaker poles connected is.
  • the hydraulic device sits on the flange plate 10, which, as can be seen from Figure 3, in cross section in has substantially square distribution rail 18 the flange plate side side surface 19 each one Piston unit 20 and on its opposite Side surface 21, which is located on the flange side, in each case Switch valve 22 attached to each circuit breaker pole are. Since a circuit breaker a total of three Circuit breaker poles are also three working piston units and three switch valves 22a, 22b and 22c present, whereby, as can be seen more clearly from FIG is, the individual switching valves 22a, b and c, respectively an electromagnetic system 23, 24 for two switching circuits and a solenoid system 25 for a turn-on circuit assigned.
  • the energy store On the side surface 26 in the area between the changeover valves 22b and 22c, said energy store is located 36, which is shown in more detail in FIG.
  • the Storage elements 37 of the energy store are several Disc springs connected in series are.
  • At the opposite of the distribution rail 18 There is a retaining washer at the end of the plate springs 37 38.
  • the piston 40 is in a cylinder space 41 arranged, the space 41a to the left of the piston, ie the one with the smaller piston area, and the space 41b right of the piston 40, that is, the one with a larger piston area contain pressure fluid on both sides.
  • the piston chamber 41 and that bore 42 which guides the piston rod 39 is accommodated in a cylinder block 43 which is on the distribution rail 18 is attached, the distribution rail even the piston chamber 41 on the larger piston area opposite side limited.
  • the cylinder block 43 has a collar-like projection 44, which delimits the piston chamber 41 and into a Indentation 45 on the side surface 26 of the distribution rail 18 engages. That the collar or the collar-like projection 44 has an annular seal 46 on its outside, with which a seal is created is a matter of course.
  • the longitudinal bore 34 which with the low pressure container connected is.
  • a transverse bore runs out of space 41b 47 towards the longitudinal bore 35.
  • Via additional cross bores (without reference numbers) in the distribution rail 18 and in the cylinder block 43 is the longitudinal bore 34 with the Room 41a connected, so that leaking oil on the piston 40 is discharged to the low pressure container.
  • the seal between two components for example the seal between a bore 53 in a module 54 and a transverse bore 55 is made in the distribution rail a socket 56 which separates the joint 57 between the two Share connects or overlaps, being on both sides of the Parting line 57 in the bushing 56, ring seals 58, 59 introduced are.
