Definitions
- the invention relates to a spindle drive for a disconnector and / or earthing switch according to the preamble of claim 1.
- the invention can be used, for example, in the case of combined high-voltage isolating and earthing switches.
- a drive device for an electrical isolating switch which has a rotatably mounted spindle which is coupled in terms of drive to the movable switching element of the isolating switch, so that the movable switching element is actuated when the spindle is rotated.
- a gearwheel is attached to the spindle, which meshes with a toothed drive coupled to an electromotive drive for its rotation and thus for actuating the movable contact piece.
- the spindle can also be turned with a hand crank.
- the gearwheel can be displaced between two positions on the spindle by the hand crank, whereby it meshes with the toothed drive in the first position and is free of the toothed drive in the second position .
- Controllable locking elements are provided between the hand crank and the spindle.
- DE 41 42 548 C2 discloses a drive for a disconnector with a drive shaft that can be driven by a motor or by hand and acts on the switch, a worm gear designed to transmit force from the motor to the drive shaft being provided.
- a drive for the movable contact piece of an isolating earthing switch is known, the contact piece drive shaft being coupled to a drive disk provided with two radial slots forming a V-shape is.
- Two parallel and linearly displaceable drive elements are provided which each engage in one of the slots and pivot the drive disk from the central position into the first and second positions.
- the drive elements can be formed by roller drivers screwed onto threaded spindles each driven by a motor, with a bolt projection which engages in the associated slot.
- the invention has for its object to provide a spindle drive for an isolating and / or earthing switch in an optimized design.
- the advantages that can be achieved with the invention are, in particular, that in the proposed spindle drive no deflection with respect to the direction of movement is required, but rather a linear adaptation takes place. No gearbox is required, which results in high efficiency.
- the movement is transmitted 1: 1.
- the parts to be moved can be easily stored.
- a single motor is sufficient for the multi-pole (multi-phase), for example three-pole movement of the switching device.
- the motor can be positioned very precisely with little force via the spindle.
- the set positions "contact”, “grounding”, “middle position” can be kept very simple.
- FIG. 1 is a side view of a switch chamber housing with spindle drive
- Fig. 2 shows a side section through the spindle drive.
- FIG. 1 a side view of a switch chamber housing with spindle drive is shown.
- a switching chamber housing 1 of a gas-insulated switchgear can be seen, in the interior of which several busbars 2 run, a three-pole (three-phase), combined disconnector and earthing switch 20 being provided as the switching device.
- This combined disconnector and earthing switch 20 has a central contact carrier 5 per pole (phase), which is in each case electrically connected to a branch 21.
- the isolating and earthing switch 20 also has: • an earthing switch contact 4 per pole, which is connected to the housing wall of the switching chamber housing 1, which is at ground potential, • an isolating switch contact 18 per pole, which is connected to a busbar 2.
- the disconnector and earthing switch 20 alternatively enables salad an electrical connection busbars 2 - isolating switch contacts 18 - contact pins 16 - contact carrier 5 - branch 21 (position "contact”), • an electrical connection branch 21 - contact carrier 5 - contact pins 16 - earthing switch contacts 4 - earth potential of the housing wall of the switching chamber housing 1 (position "earthing "), • • • a separation between branch 21 and busbars 2 and between branch 21 and earth potential of the housing wall of the switching chamber housing 1 when the contact pins 16 are in the middle position within the contact carrier 5 (position" middle position ").
- the contact pins 16 are connected via an insulation rod 15 per pole (phase) and a connecting yoke 13 common to all poles (phases) to a spindle 10, as a result of which the linear displacement desired for carrying out switching operations is achieved the contact pins 16 relative to the fixed earthing switch contacts 4 and circuit breaker contacts 18.
- the spindle 10 (translatory spindle movement) is driven by rotating a spindle nut 11 which is rotatably mounted in a spindle nut housing 6 via a bearing 7.
- the spindle nut 11 can be rotated, for example, using a motor and a V-belt or by using at least one gear wheel (in which case the spindle nut 11 is provided with an external ring gear).
- a single motor is advantageously sufficient to carry out the three-pole (three-phase) movement of the contact pins 16 of the disconnector and earthing switch.
- a manual drive of the disconnecting and earthing switch 20 acting on the spindle 10 is also provided.
- busbars 2 and the branch 21 from the switching chamber housing 1 are carried out in a generally known manner using several suitable insulating flanges 3.
- FIG. 2 shows a side section through the spindle drive.
- a section of a switching chamber housing 1 with the three-pole (three-phase), combined disconnector and earthing switch 20 can be seen.
- Three contact carriers 5 are used for guiding the contact pins 16 and for optionally contacting these contact pins 16 with isolating switch contacts 18 or earthing switch contacts 4.
- the electrical contacting itself is expediently carried out in each case via spiral spring contacts (contact rings) 19 which enclose the contact pins 16 resiliently and closely in the case of contact.
- the contact pins 16 are connected via three separate insulation rods 15 to a common connecting yoke 13, on which the spindle 10 and on each side of the spindle a guide pin 22 are mounted, both the spindle 10 and the two guide pins 22 the housing wall of the switching chamber housing 1 break through.
- the translationally movable spindle is driven using the rotatable spindle nut 11, which is rotatably mounted in the spindle nut housing 6 using a bearing 7.
- the two guide bolts 22 slide in linear guides 12, which are firmly connected to the housing wall of the switching chamber housing 1.
- Gas-tight, cap-shaped covers 14 engage on the outside of the housing wall of the switching chamber housing 1 via the guide bolts 22 and the spindle 10. There is insulating gas 17 in the interior of these covers 14, as well as in the interior of the switching chamber housing 1.
- the linear guides 12 result in a very precise Immersion of the contact pins 16 in the spiral spring contacts 19.
- a sealed position indicator 8 for displaying the current position of the disconnector and earthing switch 20 is expediently carried out with the aid of the guide bolts 22 which move translationally within the covers 14.
- the spindle and the associated drive components are located in the gas space of the switch chamber housing.
- the geometric design of the spindle drive also makes it possible to lead the individual phases out of the switching chamber housing 1 in an isolated manner. This is expediently carried out via the insulation rods 15, which are guided through sealed openings through the wall of the switching chamber housing 1, with the connection yoke 13, spindle 10, spindle nut 11, spindle nut housing 6, bearing 7, guide pin 22, linear guide 12 and position indicator 8 outside in this alternative embodiment of the interrupter housing 1 are arranged.
- the drive is not limited to a certain number of phases, i. H. the drive is universally suitable for switching devices with two, three, four etc. poles (phases).
- a single drive + a single control serves to actuate several phases (poles).
- a single control serves to actuate several phases (poles).
- a separate spindle with separate drive is provided for each phase (pole), whereby a separate control is used for the actuation of each phase (of each pole).
- Single-pole short interruptions can be implemented with this embodiment.
