Definitions
- the invention relates to a switch unit with an on-load tap changer and a drive unit, as well as a method for performing a changeover using the switch unit.
- On-load tap changers are known from the prior art and usually have a diverter switch and a selector.
- the on-load tap-changer is usually actuated by means of a motor drive in conjunction with a spring energy store.
- the motor drive preloads the springs of the spring energy store.
- compression springs are compressed or tension springs are stretched. From a defined mechanical point, the energy introduced into the springs is suddenly released and the on-load tap changer is actuated. This type of actuation has no way of controlling the energy required for switching, at least from the point at which the spring energy is released.
- a further object of the invention is to create a method for carrying out a switchover using the switching unit, which can be carried out safely and efficiently.
- the invention proposes a switch unit, comprising:
- the drive system is mechanically coupled to the on-load tap changer and actuates it;
- the drive system uses the actuating shaft as a store for kinetic energy in such a way that the actuating shaft is accelerated and the switching means are actuated by means of kinetic energy from the actuating shaft and other energy provided by the motor.
- the switching unit according to the invention enables the switching means to be actuated particularly efficiently and thus the on-load tap changer to be switched over.
- the actuating shaft is initially accelerated and absorbs kinetic energy. During this phase, the actuating shaft is mechanically connected to the switching means, but does not yet actuate them.
- the switching means are only actuated from a point defined by the design.
- the kinetic energy of the actuating shaft and the energy from the motor of the drive system are then used here in order to actuate the switching means and thus carry out switching of the on-load tap changer.
- the mass of the actuating shaft and the motor of the drive system are optimally matched to the switching means.
- the switching means When the switching means is actuated, this prevents the engine speed from collapsing in such a way that the speed falls below a minimum value. As a result, switching times are always adhered to. Switching resistors are not subjected to a circulating current for too long.
- a precisely adapted motor is used that is not oversized. The switch unit thus becomes inexpensive.
- the momentum of the actuating shaft is thus used to optimally carry out a load shift.
- the switch unit can be designed in any way, where
- the actuating shaft and the switching means are mechanically coupled in such a way that the actuating shaft actuates the switching means after a specified angle of rotation.
- the actuating shaft can have cams on its outer surface, which are partially distributed circumferentially.
- the switch unit can have a plurality of switching means, which include vacuum interrupters and/or selector contacts.
- the switching means could include operating levers which travel over the outer surface of the operating shaft by means of rollers. When the actuating shaft is rotated, the switching means are only actuated when the respective roller of an actuating lever hits a cam.
- the vacuum interrupters are closed and opened accordingly when actuated.
- the selector contacts make contact with fixed contacts that are connected to taps of a control winding.
- the switch unit can be designed in any way, where
- the actuating shaft is turned at least once when the on-load tap-changer is actuated and the motor shaft is turned several times.
- the motor shaft rotates several times when performing a shift.
- the actuating shaft rotates at least once and a maximum of three times during a switchover, i.e. at least 360 degrees or a maximum of 1080 degrees.
- the switch unit can be designed in any way, with a moment for accelerating the actuating shaft being approximately or greater than a moment for actuating the switching means or switching means.
- the invention proposes a method for performing a changeover using a switch unit, wherein: in a first step, the actuating shaft is accelerated by the motor of the drive system, the actuating shaft absorbs kinetic energy and no switching means is actuated; in a second step, the switching means are actuated by means of the kinetic energy from the actuating shaft and energy from the drive system; in a third step, the actuating shaft is braked by the motor of the drive system.
- the switching process is divided into several steps.
- a first step the actuation shaft is accelerated with the motor of the drive system.
- the actuating shaft stores kinetic energy.
- the switching means are actuated. The energy required for this is taken from the kinetic energy of the actuating shaft and additional energy from the motor of the drive system.
- 3a-3b show three travel profiles of drive systems with different actuating shafts using two diagrams each;
- FIG. 4 shows a flow chart for switching over a switch unit.
- FIG. 1 shows a schematic representation of an exemplary embodiment of a switch unit 1 with an on-load tap changer 17 and a drive system 3, which is connected via a drive shaft 16 to the on-load tap changer 17 and its actuating shaft 20 and the multiple switching means 21.
- the on-load tap changer 17 can include a diverter switch, selector, double turner, turner and/or preselector or can also be designed as a load selector.
- the switching means 21 can be designed as vacuum interrupters and/or simple contacts or selector contacts that are arranged in oil.
- the drive system 3 includes a motor 12 which can drive the drive shaft 16 via a motor shaft 14 and optionally via a gear 15 .
- the drive shaft 16 is connected to the actuating shaft 20 in the on-load tap changer 17 .
- a control device 2 of the drive system 3 includes a power unit 11 which contains, for example, a converter (not shown) for the controlled or regulated energy supply of the motor 12 and a control unit 10 for controlling the power unit 11 , for example via a bus 19 .
- the drive system 3 has a feedback system 4 which is functionally assigned to the drive shaft 16 .
- the feedback system 4 can be a transmitter system 13 .
- the transmitter system 13 can be part of the feedback system 4 .
- the feedback system 4 or the encoder system 13 is connected to the power section 11 . Furthermore, the encoder system 13 is coupled directly or indirectly to the drive shaft 16 .
- the encoder system 13 is set up to detect a first value for a position, such as an angular position, in particular an absolute angular position, of the drive shaft 16 and thus also of the actuating shaft 20 .
- the encoder system 13 can include, for example, an absolute value encoder, in particular a multi-turn absolute value encoder or a single-turn rotary encoder, which is attached to the drive shaft 16, the motor shaft 14 or another shaft whose position is clearly linked to the position of the drive shaft 16 is, is attached.
- the position of the drive shaft 16 or actuating shaft 20 can be clearly determined from the position of the motor shaft 14, for example via a transmission ratio of the gear 15.
- the encoder system 13 can include a virtual rotary encoder, which determines the position of the motor shaft 14 and from this the position the drive shaft 16 or the actuating shaft 20 derives.
- the feedback system 4 is set up to record a value for the position of the drive shaft 16 and thus also a position of the actuating shaft 20 .
- the value for the position of the drive shaft 16 is made available as a protocol.
- the value for the position of the drive shaft 16 is determined from a rotor position of the motor 12 .
- inductive feedback from the movement of the rotor in the motor windings of the motor 12 can be used. Because a strength of the feedback varies periodically, the rotor position can be approximately determined, in particular by means of signal analysis, such as for example by FFT analysis. Since a full revolution of the drive shaft 16 corresponds to a large number of revolutions of the rotor, the position of the drive shaft 16 and also of the actuating shaft 20 can be deduced from this with much greater accuracy.
- the encoder system 13 can also be designed as a combination of a virtual rotary encoder and an auxiliary contact that is connected directly or indirectly to the drive shaft 16 .
- the value for the position of the drive shaft 16 is then formed from the signals from the virtual encoder and the auxiliary contact.
- the control device 2 in particular the control unit 10 and/or the power unit 11, is set up to control or regulate the motor 12, depending on a feedback signal which the feedback system 4 generates based on the value.
- the control device 2 for example the control unit 10, uses the value for the position of the drive shaft 16 or actuating shaft 20 to determine the position of the on-load tap changer 17.
- the control device 2, for example the control unit 10, controls and regulates the motor 12 so that it reaches a specified speed according to the specifications.
- the actuating shaft 20 and the switching means 21 are mechanically connected or coupled to one another.
- the actuating shaft 20 can have cams which, from a specific point in the rotation of the actuating shaft 20, open and close the switching means 21, in particular vacuum interrupters, for example via toggle levers. It is assumed here that the energy required to actuate the switching means 21 is always the same. In other words, a constant torque must always be applied in order to actuate the switching means 21.
- FIG. 2 shows a possible driving profile of the motor 12 for switching or actuating the switch unit 1 and in particular the division of the switching into several steps in different diagrams 25,26. These diagrams are arranged one below the other for better explanation.
- the speed n of the motor 12 is plotted over time.
- the actuating shaft 20 is accelerated via the motor 12 of the drive system 3 .
- the speed of the motor 12 increases linearly in a first step 60 over a specific time until a specific value, ie a specific speed, is reached.
- the course of the kinetic energy is shown in the second diagram 26, which is shown below the first diagram 25.
- the kinetic energy is formed from the rotational speed and the inertia of the actuation shaft 20 and the inertia of the switching means 21 .
- the first step 60 of the switch is shown delimited. As the motor 12 of the drive system 3 accelerates the operating shaft 20, the kinetic energy in the entire mechanical system of the switch unit 1 increases.
- the switching means 21 are now actuated.
- the kinetic energy of the actuating shaft 20 is used to actuate the switching means 21.
- the momentum of the mass of the actuating shaft 20 supports the motor 12 in actuating the switching means 21.
- the actuating shaft 20 is used as a store for kinetic energy.
- the speed of the motor 12 falls briefly when the switching means 21 is actuated and then rises again to the specified value.
- the mass inertia of the actuating shaft 20 is small in this example. A small moment must therefore be applied in order to accelerate the operating shaft 20 . Only little kinetic energy is stored in the actuating shaft 20. Since this energy is significantly less than the work required to actuate the switching means 21, the speed of the motor 12 drops sharply, since the non-ideal drive system 3 requires a certain amount of time to feed the lost energy back into the system or to bring in In other words, the energy drawn from the system is very large in relation to the kinetic energy present before the switching elements 21 were actuated. In this case, the minimum value of the speed 34 is undershot, which has a negative effect on the switchover. For example, switching times in the on-load tap changer 17 cannot be adhered to.
- the second pair of diagrams 40, 41 in FIG. 3b shows the travel profile of an embodiment of the switch unit 1, in which the mass inertia of the actuating shaft 20 is very large. A large moment 42 must therefore be applied in order to accelerate the actuating shaft 20 . A great deal of kinetic energy is stored in the actuation shaft 20 . Since this energy is significantly greater than the work required to actuate the switching means 21, the speed of the motor hardly drops as soon as the moment of the switching means 21 occurs. In other words, the energy drawn from the system is very small in relation to the kinetic energy present before the switching means 21 was actuated. The speed does not fall below the minimum value 44, which has a positive effect on the switchover.
- the third area 44 shows the torque required to brake the actuating shaft 20.
- a driving profile of an optimal embodiment of the switch unit 1 is shown in which the inertia of the Actuating shaft 20 are matched to the motor 12 to the torque 53 required when the switching means 20 is actuated.
- the mass of the actuating shaft 20 is just large enough that when the switching means 21 is actuated, the speed just remains above a minimum value and the moment 52 for accelerating the actuating shaft 20 does not become too large.
- a smaller, more suitable motor 12 can be selected.
- the mass inertia of the actuating shaft 20 is chosen so large that the absolute value of the torque 52 for accelerating and braking the actuating shaft 20 is greater than or equal to the torque that is required by the switching means 21 during the switchover or when the on-load tap changer 17 is actuated .
- FIG. 4 shows a method for carrying out a changeover using switch unit 1 .
- the actuating shaft 20 is accelerated by the motor 12 of the drive system 3 .
- the actuating shaft 20 absorbs kinetic energy.
- the switching means 21 are not yet actuated.
- the switching means 21 are actuated.
- the kinetic energy of the actuating shaft 20 and the energy of the drive system 3 is used.
- the actuating shaft 20 is braked by the drive system 3 .
- the actuation of the on-load tap changer is understood as switching.
- a switchover takes place from one winding tap of a tapped transformer to an adjacent winding tap of the tapped transformer.
