Abstract
The utility model provides a kind of dynamic panel vehicle motor control loop, the major loop switch and by-pass switch that are in parallel is provided with between power supply and dynamic panel vehicle motor, described major loop switch is provided with successively the communication switch of isolating switch, electric capacity and connection communication port, described by-pass switch is provided with isolating switch.During described major loop switch conduction, by-pass switch disconnects, if by-pass switch conducting during major loop switch fault, and direct boot disk vehicle motor, thus the safe and stable operation ensureing generator.
Description
Technical field
The utility model belongs to motor control technology field, relates to a kind of dynamic panel vehicle motor control loop.
Background technology
In thermal power generation unit, dynamic panel vehicle motor jiggering before starter-generator, can be used for smooth starting unit.When after steam turbine admission, rotor revolution number slowly increases, and when exceeding a certain speed, centrifugal force makes jiggering meshing gear separately, and jiggering stops.And when after halt turbines, just needing to start jiggering makes the continuous regular upset of turbine rotor, prevent bending shaft.This is that cylinder temperature is high due to after halt turbines, turns if do not coiled; rotor is under self gravitation effect, and high temperature rotating shaft slight curves can occur, and this is unallowed in running; vibration can be caused to strengthen, friction packing etc., and jiggering will be started carry out running and just can avoid.So once go wrong in jiggering control loop and will directly have influence on the normal startup of turning motor, work the mischief to generator.
Utility model content
The technical problem that the utility model solves is to provide a kind of dynamic panel vehicle motor control loop, for Electric Machine Control provides by-pass switch, once major loop breaks down, and direct boot disk vehicle motor, thus the safe and stable operation ensureing generator.
The utility model is achieved through the following technical solutions:
A kind of dynamic panel vehicle motor control loop, the major loop switch and by-pass switch that are in parallel is provided with between power supply and dynamic panel vehicle motor, described major loop switch is provided with successively the communication switch of isolating switch, electric capacity and connection communication port, described by-pass switch is provided with isolating switch.
During described major loop switch conduction, by-pass switch disconnects, if by-pass switch conducting during major loop switch fault.
In described major loop switch, isolating switch is often opened, and communication switch turns off or conducting according to the signal of communication port.
Compared with prior art, the utility model has following useful technique effect:
The dynamic panel vehicle motor control loop that the utility model provides, be made up of the major loop switch be in parallel and by-pass switch, during major loop switch conduction, by-pass switch disconnects, wherein the isolating switch of major loop switch is often opened, communication switch turns off or conducting according to the signal of communication port, is by major loop switch control rule normal operation; If by-pass switch conducting during major loop switch fault, direct conducting isolating switch, direct boot disk vehicle motor, thus the safe and stable operation ensureing generator, reducing in jiggering control loop goes wrong affects the risk of generator stable operation.
Accompanying drawing explanation
Fig. 1 is electrical block diagram of the present utility model.
Embodiment
Below in conjunction with accompanying drawing, the utility model is described in further detail, described in be to explanation of the present utility model instead of restriction.
See Fig. 1, a kind of dynamic panel vehicle motor control loop that the utility model provides, the major loop switch and by-pass switch that are in parallel is provided with between power supply and dynamic panel vehicle motor, described major loop switch is provided with successively the communication switch of isolating switch, electric capacity and connection communication port, described by-pass switch is provided with isolating switch.
During described major loop switch conduction, by-pass switch disconnects, if by-pass switch conducting during major loop switch fault.
In described major loop switch, isolating switch is often opened, and communication switch turns off or conducting according to the signal of communication port.
In above-mentioned electric disc vehicle motor control loop, be made up of the major loop switch be in parallel and by-pass switch; During major loop switch conduction, by-pass switch disconnects, and wherein the isolating switch of major loop switch is often opened, and communication switch turns off or conducting according to the signal of communication port, is by major loop switch control rule normal operation.
Once major loop breaks down, directly by the isolating switch Buddhist monk on by-pass switch, direct boot disk vehicle motor, thus the safe and stable operation ensureing generator, reducing in jiggering control loop goes wrong affects the risk of generator stable operation.
