In order to achieve the above-mentioned object of the invention, the technical solution adopted by the present invention is that:
A kind of nine with dipole inversion grade transformer on-load voltage regulating circuit, by major loop, transition circuit, voltage rating branch structure At, which is characterized in that the major loop is made of main winding, tap-changing windings, five pressure regulation branches, a vacuum interrupter, institute It states tap-changing windings and is successively arranged five taps from top to bottom, be upper end tap, middle upper end tap, middle-end tap, middle lower end respectively Tap, lower end tap;Five pressure regulation branches are separately connected five taps of tap-changing windings and directly empty arc-chutes are inscribed with major loop End is connected, each one selection switch of pressure regulation branch series connection;Main winding output end is separately connected tap-changing windings by a polarity switch Upper end tap and lower end tap;The external connection end of the vacuum interrupter of the one end and major loop in transition circuit connects, transition circuit One end is divided into two branches and connects one group of linked switch, two, transition circuit branch respectively with upper end tap in tap-changing windings Connection is connected with middle lower end;Voltage rating branch one end is connect with main winding output end, and the other end goes out with the straight sky of major loop The inscribed end connection of arc chamber.
Specifically, the major loop includes main winding L, polarity switch KaKb, tap-changing windings, selection switch K1, choosing Select switch K2, selection switch K3, selection switch K4, selection switch K5, vacuum interrupter D0.Tap-changing windings by voltage regulation coil L1, Tetra- sections of voltage regulation coil L2, voltage regulation coil L3, voltage regulation coil L4 coil compositions, including upper end tap X1, middle upper end tap X2, middle-end Tap X3, middle lower end tap X4, lower end tap X5 totally 5 taps.Five taps of tap-changing windings pass through respectively selection switch K1, Selection switch K2, selection switch K3, selection switch K4, selection switch K5 are connect with the inscribed end of vacuum interrupter D0.
The selection switch K1, selection switch K2, selection switch K3, selection switch K4, selection switch K5 are unidirectionally to open It closes, wherein selection switch K1 and selection switch K5 must be vacuum interrupters, selects switch K2, selection switch K3, selection switch K4 is either vacuum interrupter is also possible to regular tap.
The transition circuit by linked switch K6K7 be divided to be two branches, two branches respectively with upper end in tap-changing windings Lower end tap X4 connection in tap X2, tap-changing windings, the transition circuit other end is connect with the external connection end of vacuum interrupter D0, described Transition resistance R and vacuum interrupter D1 are in series in transition circuit.
Auxiliary switch Ke, voltage rating branch one end and main winding tap Xa are in series in the voltage rating branch Connection, the other end are connect with the inscribed end of vacuum interrupter D0.
The vacuum interrupter D0 external connection end connect regulating circuit output end with the vacuum interrupter D1 external connection end jointly Xb。
The public contact of the polarity switch KaKb is connect with main winding tap Xa;Two static contacts of polarity switch are distinguished It is connected with the upper end tap X1 of tap-changing windings and lower end tap X5.
Based on above-mentioned technical proposal of the present invention, by adjusting the polarity switch, so that it may simply and easily change access Tap-changing windings in circuit around to and then realizing positive-negative voltage-regulation.
A selection switch is connected after each tap-changing windings, each step voltage is realized in the folding of clearance selection switch Increase and decrease.
Linked switch K6K7 one disconnects then one and is closed, and K6 is in closed state, then in transition circuit and tap-changing windings Upper end tap X2 connected branch plays a role.K7 in the closure state, then lower end tap in transition circuit and tap-changing windings X4 connected branch plays a role.In related positive pressure regulation gear, linked switch K6 is in closed state always, in relevant reverse Pressure regulation gear, linked switch K7 are in closed state always.
When normal operation, the major loop is to turn on state, and the vacuum interrupter D0 of the major loop is to turn on shape State, the transition circuit is off-state, and the vacuum interrupter D1 in the transition circuit is off-state.
The vacuum interrupter D0 of the major loop replaces folding with the vacuum interrupter D1 in transition circuit during pressure regulation, Under normal operating condition, transition circuit vacuum interrupter D1 closure, transition circuit is connected.It is then turned off major loop vacuum interrupter D0, major loop are in an off state.Then selection switch is adjusted, the tap-changing windings of access major loop are adjusted.Voltage, which is adjusted, to be completed Afterwards, it is closed major loop vacuum interrupter D0, major loop is connected.Major loop and transition circuit are all in on-state, two electricity at this time Road voltage is different but is connected with each other, and the presence of transition resistance R, ensure that at this time be not in short-circuit condition in transition circuit. Then transition circuit vacuum interrupter is disconnected again, and transition circuit disconnects, and so realizes once without power-off pressure regulation process.
During positive pressure regulation, in an ON state, linked switch K6 is in closed state at the end two-way switch Ka, at Ke In off-state, voltage rating branch is in an off state.Alternately control D0 and D1 is opened and closed, and is adjusted selection switch, be can be achieved with Forward direction pressure regulation at different levels.
During reversed pressure regulation, in an ON state, linked switch K7 is in closed state at the end two-way switch Kb, at Ke In off-state, voltage rating branch is in an off state.Alternately control D0 and D1 is opened and closed, and is adjusted selection switch, be can be achieved with Reversed pressure regulation at different levels.
Before positive pressure regulation switches to reversed pressure regulation, in an ON state, K6 is in closed state to Ka, and K1 is in closed form State, D0 are in closed state, and in an ON state, only main winding L accesses circuit to major loop.
Auxiliary switch Ke, into reversed pressure regulation handoff procedure, is first being closed from positive pressure regulation, voltage rating branch is in and connects Then logical state disconnects selection switch K1 under major loop energized state, two-way switch is then gone to the end Kb by the end Ka again, is closed Close linked switch K7.Then closure selection switch K5, major loop in an ON state, then could start reversed pressure regulation, during which Regulating circuit is always maintained at only main winding access circuit.
Before reversed pressure regulation switches to positive pressure regulation, in an ON state, K7 is in closed state to Kb, and D0 is in closed form State, major loop is in an ON state.
Auxiliary switch Ke, into reversed pressure regulation handoff procedure, is first being closed from positive pressure regulation, voltage rating branch is in and connects Logical state is then turned off selection switch K5, and two-way switch is then gone to the end Ka by the end Kb again, is closed linked switch K6.Then Closure selection switch K1, major loop in an ON state, then could start positive pressure regulation.
When adjusting switching by positive pressure and back-pressure, two-way switch needs go to the end Kb by the end Ka or go to the end Ka by Kb, In two-way switch switching process, pressure adjusting structure and transition circuit are all in off-state.The setting of voltage rating branch guarantees In handoff procedure transformer will not external interruption of power supply.
In conclusion the present invention is beneficial to effect: while realizing positive-negative voltage-regulation, being provided for nine grades of pressure regulation multiple and different Transient voltage effectively reduces the voltage fluctuation during pressure regulation, improves quality of voltage.
