Abstract
The utility model provides an electroless on-load tap switch shifting structure comprising a main driving shaft disposed on an on-load tap switch oil chamber axis. The main shaft is driven by a driving motor disposed in an oil chamber through a pair of conical gears in an engaged manner. An inner wall of the oil chamber is provided with a rotary disc, two ends of which are provided with magnets having different magnetic poles. A center of the rotary disc is provided with a transmission shaft. One end of the transmission shaft is pivoted to the inner wall of the oil chamber, and the other end of the transmission shaft is connected with a third conical gear after the speed change of a gearbox. The third conical gear is engaged with the conical gears of the main driving shaft. The rotary disc is provided with a second torsion bar on a corresponding position of an outer side of the oil chamber. Two ends of the second torsion bar are provided with magnets having different magnetic poles, and a central position of the second torsion bar is provided with a locking device capable of locking a mini-sized motor rotating shaft. By using the electroless on-load tap switch shifting structure, the on-load tap switch can be conveniently tested under an electroless condition.
Description
Technical field
The utility model relates to the potential device field, especially, is the on load tap changer gear shifting structure under a kind of electroless state.
Background technology
Line voltage changes with operational mode and load, in order to improve quality of voltage.Make transformer that a specified output voltage can be arranged, normally realize pressure regulation by the position that changes a winding shunting tap, the device of connection and switching branch joint position is shunting switch, it is to adjust variation by the number of turn that changes Transformer Winding, change voltage by adjusting no-load voltage ratio, carry out the voltage adjustment.On-load voltage regulation is exactly deenergization not, allows transformer in normal operation, the bringing onto load regulation tap switch.Its principle is exactly, and when the moving contact of switch leaves not yet fully from one grade, connects transition circuit (by the electric current between two grades of the transition resistance restrictions), to guarantee not dead electricity of transformer, after moving contact arrives another shelves, disconnect again transition circuit, regulate and just finished.
Because inner CD-ROM drive motor is not worked, open to test and brought no small trouble when without electricity the time, testing on load tap changer.
Summary of the invention
In order to address the above problem, it is a kind of without electric on load tap changer gear shifting structure that the purpose of this utility model is to provide, and this on load tap changer can easily be tested on load tap changer in without electric situation.
The technical scheme that its technical problem that solves the utility model adopts is:
This comprises the main drive shaft that is arranged on the load tap changer oil chamber axis without electric on load tap changer gear shifting structure, described main drive shaft is driven by a pair of conical gear engagement by a drive motors that is arranged in the grease chamber, be provided with the torsion bar of the different magnet magnetic poles of two ends band on the inwall of described grease chamber, described torsion bar center is with a power transmission shaft, described power transmission shaft one end and grease chamber's inwall articulate, the other end is by the engagement of the conical gear on the 3rd conical gear and the described main drive shaft, outside correspondence position is provided with the second torsion bar to described torsion bar in described grease chamber, grease chamber's wall between described torsion bar and the second torsion bar is that toughened glass or resin are made, the two ends of described the second torsion bar are provided with the magnet of different magnetic poles, and the center of described the second torsion bar is provided with the lock that can lock motor shaft.
As preferably, described torsion bar replaces with rotating disk, and the center line of described rotating disk is provided with the different magnet of polarity from the intersection, edge of rotating disk, and rotating disk rotary resistance in described grease chamber is less, and power consumption is lower.
As preferably, the magnet that arranges in described torsion bar, the second torsion bar and the rotating disk is a bar magnet.
As preferably, described power transmission shaft is divided into two sections, between described two sections power transmission shafts by a gearbox mechanical connection.
The utility model has the advantage of:
Drive the second torsion bar by motor, the magnet on the second torsion bar promotes torsion bar and rotates, and torsion bar drives again described main drive shaft, makes on load tap changer also can conveniently carry out switch test in without electric situation.
Description of drawings
Fig. 1 is that the utility model is without the structural representation of an embodiment of electric on load tap changer gear shifting structure;
Fig. 2 is the rotating disk of Fig. 1 embodiment and the structural representation of the second torsion bar.
Among the figure: 1, switch grease chamber; 2, drive motors; 3, main drive shaft; 4, rotating disk; 41, magnet; 5, the second torsion bar; 51, magnet; 52, lock; 6, gearbox; 61, power transmission shaft; 62, the 3rd conical gear.
Embodiment
Below in conjunction with drawings and Examples the utility model is further specified:
Figure 1 shows that this is without the planform schematic diagram of an embodiment of electric on load tap changer gear shifting structure, Fig. 2 is the rotating disk of Fig. 1 embodiment and the structural representation of the second torsion bar, problem is now set forth as same embodiment Fig. 1, Fig. 2 to the utility model for convenience of explanation.
In the present embodiment, this comprises the main drive shaft 3 that is arranged on load tap changer oil chamber 1 axis without electric on load tap changer gear shifting structure, described main drive shaft 3 is driven by a pair of conical gear engagement by a drive motors 2 that is arranged in the grease chamber 1, be provided with the rotating disk 4 of different magnet 41 magnetic poles of two ends band on the inwall of described grease chamber 1, described rotating disk 4 centers are with a power transmission shaft 61, described power transmission shaft 61 1 ends and grease chamber's 1 inwall articulate, the other end is by connecting the 3rd conical gear 62 after a gearbox 6 speed changes, conical gear engagement on described the 3rd conical gear 62 and the described main drive shaft 3, described rotating disk 4 is provided with the second torsion bar 5 at described grease chamber 1 outside correspondence position, grease chamber's 1 wall between described rotating disk 4 and the second torsion bar 5 is that toughened glass or resin are made, the two ends of described the second torsion bar 5 are provided with the magnet 51 of different magnetic poles, and the center of described the second torsion bar 5 is provided with the lock 52 that can lock the micro motor rotating shaft.
