Existing high pressure undisturbed prepared auto restart switching.
I.e. there is provided in the present embodiment and manually boot switching and protection startup switching two ways, protection starts switching can
Use series connection switching and switch simultaneously, manually booting switching and can use switching in parallel and switch simultaneously.Wherein, series connection switches to elder generation
Tripping working power, and the stand-by power supply that closes again after confirming working power tripping, working bus bar power-off time is at least standby electricity
Source closing time.Parallel connection switches to the stand-by power supply that first closes, two power supplys to work the most side by side, then tripping working power.Cut simultaneously
Be changed to close stand-by power supply order jumping after working power order, but sent before working power tripping, this kind of mode between
Between series connection switching with switching in parallel, working bus bar power-off time at 0ms to stand-by power supply closing time, can be short by arranging one
Time delay adjusts.
Below to be carried out as a example by protection starts switching by controller 114, concrete real to high pressure undisturbed electric supply installation
The mode of executing carries out detailed explanation.
Divide by switch speed, controller 114 carry out protection start switching include being switched fast, same-slope curve
With three kinds of modes of remnant voltage switch.
It is switched fast:
First high pressure inlet wire 118 and the second high pressure inlet wire 126 are the most standby, and wherein an inlet wire is given as working power and used
Electricity equipment is powered, and the corresponding bus connected is working bus bar, and another inlet wire is as stand-by power supply.When after working power tripping,
Frequency difference between controller 114 evaluation work bus residual voltage Uab and the primary voltage UI of stand-by power supply and phase angle difference.When frequency difference and
When phase angle difference is all in set point, immediately send close stand-by power supply closing pulse to stand-by power supply, complete to be switched fast.By
Quick in the action of chopper, so dash current when closing a floodgate, surge voltage are all in safety value, and the dead electricity time is short, protects
Demonstrate,prove the properly functioning of electricity consumption.It is safe for closing a floodgate in 60 ° for electrical equipment when phase angle difference.In the present embodiment, work as frequency difference
It is switched fast when being 30 ° for 1Hz, phase angle difference.
The same period switches:
If being switched fast unsuccessful after working power chopper tripping, then working bus bar residual voltage Uab is likely to enter combined floodgate
Unsafe region, does not the most allow switching.After working bus bar residual voltage Uab crosses 180 °, it may appear that working bus bar residual voltage Uab is with standby
By the primary voltage UI of power supply coincidence point for the first time, now auxiliaries-supply circuit-breaker closes.The same period, switching made again synchronization cap-ture cut
Change, when the handover success same period, won the combined floodgate chance of stand-by power supply, now the residual voltage of working bus bar about 65%～
70%, highly advantageous to motor start-up, dash current and surge voltage are the least simultaneously.
In same-slope curve, without additional excitation and without additional motive power, therefore there is relatively large frequency-difference and pressure reduction in motor
Situation, the stand-by power supply as long as phase angle difference is closed in certain limit near 0 °, motor quickly can recover normal asynchronous operation.With
Phase catches switching and can use constant leading angle principle and use constant leading time principle two ways to realize.
Use constant leading angle principle:
The parameter now set is as frequency difference (typically taking 4～5Hz) and leading angle (typically taking 90 °).Evaluation work in real time
Bus residual voltage Uab and the phase angle difference of stand-by power supply primary voltage UI and frequency difference, when the advanced stand-by power supply of working bus bar residual voltage Uab enters
When the phase angle of line voltage UI is setting value, if frequency difference is less than setting value, then send out closing pulse.If frequency difference exceedes setting value, then
Abandon closing a floodgate, proceed to remnant voltage switch.
Use constant leading time principle:
The parameter now set (is equal to send closing pulse to standby electricity as frequency difference (typically taking 4～5Hz) and leading time
The source chopper main contact Guan Bi time only).In real-time evaluation work bus residual voltage Uab and the phase of stand-by power supply primary voltage UI
On the basis of angular difference and frequency difference, according to single order and the second dervative of the change of working bus bar residual voltage Uab frequency, calculate working bus bar residual
The time of pressure Uab advanced stand-by power supply primary voltage UI, when leading time be setting value and frequency difference less than setting value, then send out conjunction
Lock pulse.If frequency difference exceedes setting value, then abandon closing a floodgate, proceed to remnant voltage switch.
Remnant voltage switch:
When catch the same period switching do not have successful time, proceed to remnant voltage switch.Remnant voltage switch is when working bus bar residual voltage Uab declines
Reduce to 20%～during 40% rated voltage, make stand-by power supply close a floodgate, it is achieved switching.
