Definitions
- the invention relates to a tap changer with switching monitoring according to the preamble of the first Claim.
- a tap changer is from the applicant's company publication "Step switch type MD - inspection instructions" Printing imprint IA 110/01 en already known.
- the known tap changer is intended for triangular use and has a two-column structure.
- the Pillar 1 consists of a two-pole diverter switch and a single-pole selector
- the pillar 2 on the other hand, consists of a single-pole diverter switch and a two-pole selector.
- the diverter switch one pole of the pillar 1 is connected to the voter of pillar 2 through voter connection lines connected.
- Both tap changer columns 1 and 2 are mechanical via a horizontal one Drive shaft between the gear stages of the tap changer heads of pillars 1 and 2 with each other coupled and operated together by a motor drive.
- Each column has an energy accumulator that is pulled up by the common motor drive.
- To the lift mechanism has a pull-up slide and a jump slide; between these compression springs are arranged in both components.
- the energy accumulator is pulled open, its respective pull-up slides linearly relative to the position of the still fixed jumping slide this moved so that the intermediate compression springs are tensioned.
- the jump slide which has been locked until then is released and follows abruptly - hence the name - also linearly with the movement of the slide to.
- the rapid longitudinal movement of the jumping sled is converted into a via a crank mechanism Rotary movement of the output shaft converted, which in turn the respective diverter switch corresponding column actuated.
- the simultaneous switching of pillar 1 and pillar 2 is constantly monitored by a switch controlled.
- This switching monitoring ensures that the diverter switches are always in both columns Switch together and that the common motor drive is switched off in the event of a fault.
- This switching monitoring has a backdrop on each pillar, each on the slide of the The energy accumulator is arranged and its abrupt - already described above Traverses longitudinal movement after release. A crank engages in this setting, which the described longitudinal movement of the backdrop in a rotational movement of a drive shaft Switching monitoring converted.
- This drive shaft leads through the tap changer from the area of the Lift mechanism vertically upwards in the area of the respective tap changer head.
- There are magnetically operated signaling contacts are provided, which depend on the direction of rotation depending on the position of the Drive shaft of the switch monitoring can be operated. In the respective position of the diverter switch the associated signaling contacts are closed. With different positions of the two Diverter switch in the columns and thus different position of the signaling contacts Motor drive immediately through a monitoring circuit, in which the signaling contacts are included
- the linear movement of the spring carriage is thus Lift mechanism used as a monitoring criterion; this linear movement becomes a Rotational movement of the drive shaft and thus a pivoting movement of metal flags on their used the upper end to actuate the signaling contacts.
- the object of the invention is therefore to provide a generic tap changer with an improved Specify switching monitoring that no longer has the disadvantages described, safe and works reliably and a uniform movement map of the switching process for everyone Load switching generated.
- the tap changer according to the invention has the Shift monitoring a direct movement tapping from the rotating output shaft in turn actuates the diverter switch directly.
- the tapped movement shows exactly the same time course as the movement of the output shaft and thus the entire Switching sequence of the diverter switch, the individual contacts of which are actuated by the output shaft.
- the movement tapping continues to take place at the last possible mechanical link within the whole gear train. This eliminates the risk of incorrect information about the switching sequence and the status of the diverter switch in the event of faults within the Gear train, d. H. on the components downstream of the lift mechanism.
- uniform movement image by the switching monitoring in which a rotary movement of the output shaft to the diverter switch in a corresponding rotary movement the drive shaft of the switching monitoring is converted, allows a simple Variety of monitoring and monitoring functions.
- a representation is and Monitoring of the path-time curve or angle of rotation-time curve during load switching possible.
- the figure shows a schematic representation of various assemblies of an inventive Energy accumulator.
- the oil vessel surrounding the entire tap changer is not shown in the figure.
- a horizontal bearing plate 1 in the center of which is centric downward output shaft 2 runs.
- the output shaft 2 leads to below arranged diverter switch, not shown here.
- On the base plate 1 is also here Energy storage, not shown, arranged at the beginning of each actuation of the tap changer Motor drive is pulled up in a known manner.
- Corresponding energy stores are known in large numbers from the prior art. So are about known from DE-PS 19 56 369 and DE-PS 28 06 282 energy storage, in which between an elevator slide and a spring slide force storage springs are arranged. To The spring sledge triggers a linear movement in these energy stores, which means a crank mechanism is converted into a rotational movement of the output shaft 2.
- a gear wheel or segment 4 there is a further toothing on the output shaft 2 as a gear wheel or segment 4 arranged, which with a separate gear 5, which is rotatably mounted on an axis 6, interacts.
- the gear wheel 5 in turn corresponds with its external toothing Tooth segment 7, which with the drive shaft 9 mounted in a bearing 8 of the shift monitoring in Connection is established.
- This drive shaft 9 leads in a known manner up into the area of here Not shown tap changer head and actuates a here only shown schematically Switch monitoring contact module 10.
- This contact module 10 can have magnetically operated contacts, Have reed contacts, for example, according to the prior art; instead, at the top of the Drive shaft 9 also other means for monitoring, for. B. resolver or the like.
- the movement is not tapped in Area of the energy accumulator, but only on the output shaft 2, which leads to the diverter switch, more precisely, their interlocking 4.
- This will be the two advantages of Invention achieved in a simple manner; through the described interacting gears on the one hand there is a uniform transmission of movement, on the other hand it is really exactly that Movement detects - namely the rotary movement of the output shaft 2 - which actually and directly without the interposition of further mechanical elements on the diverter switch and its in predetermined switching sequence acts successively individual contacts.
- this invention is not based on the monitoring of tap changers mentioned in the introduction two-column arrangement limited to triangular applications.
- the invention is also applicable to monitor the switching sequence of a normal single-column tap changer visualize.
- z. B. a resolver at the upper end of the drive shaft 9 of the switching monitoring or similar technical means, it is possible to control the entire sequence of movements of the output shaft 2 and thus to capture the entire switching sequence when switching loads, e.g. B. as a path-time curve, d. H. here as a rotation angle-time curve, and to compare it with previously stored target values, to generate error or warning messages for certain deviations.
- one incomplete rotation of the output shaft 2 by a prescribed angle of rotation is an indication that that the diverter switch is not latched again, d. H. has not reached its new end position.
- exceeding the usual time for a load switchover is, for. B. an indication of one increased mechanical resistance that had to be overcome and thus for mechanical Defects in the tap changer.
