In addition to electric voltage exception, it is also contemplated that pipeline is abnormal, the oil pressure in the oil feed line of electronic oil pump 103 of starting going to a nursery
Abnormal to decline or abnormal rising, then sending alarm sounds by warning device may cause the oil pressure of voltage pulsation abnormal.Report
Alarm device is the integrated warning system on ship.
The electric power that the UPS102 of main power source 114 or the first battery 110 can be automatically selected in first UPS102 is provided to electricity
Dynamic oil pump 103.
Wanting to ensure that ice breaker during opening ice, does not make active force because of voltage pulsation ----propeller loses dynamic
Power is it is necessary to ensure propulsion motor in work, and propulsion motor is in itself due to inertia, will not be shut down after 2-3 seconds in decompression, and
The control section of the starter of itself is also to have what UPS powered.So it is accomplished by seeing its accessory system, if can also shoulder this
2-3 seconds, and this accessory system just includes cooling system (cooling blower and fresh water of motor itself, seawater cooling by analysis
Pump) and lifting system (jacking pump).It is also, if without this programme, even if propulsion motor itself has no problem, but it is such as cold
But system-down, then propulsion motor will be forced to shut down.If same reason generating equipment --- diesel generating set will
It is that can not provide electricity, also results in propulsion motor shutdown, and the accessory system of main diesel engine shutdown can be caused, then is main diesel oil
The dynamic oil pump of electromechanics, the cooling system (fresh water, cooling sea water pump) of main diesel engine etc., so in this scenario, for ice breaker
Specific power supply system, by it is above-mentioned these there may be the factor of buterfly effect all to being picked out, and solve voltage ride-through
Problem.
The technical scheme of the present embodiment, by the ice breaker for needing to realize voltage ride-through, being in ice breaker starter
The control loop in portion provides uninterrupted power source UPS all the way and is powered, when during voltage dip, the power supply of control loop
The uninterrupted power source being converted on ship of being powered by main power source is powered, and solves the influence of fluctuations by main power network on ship, control loop
The problem of power supply instability, the effect that generating equipment and power-equipment work steadily is reached.Meanwhile, in above-mentioned technical proposal
On the basis of, by adding emergency power supply and warning device, it is to avoid when uninterrupted power source UPS breaks down, it is impossible to be electronic
Oil pump, the first cooling system, the situation of the second cooling system and lifting system and starter supply electric power, it is to avoid because
Single auxiliary equipment is because voltage pulsation causes chain reaction, and causing the power supply of propeller can not normally realize.
Note, above are only presently preferred embodiments of the present invention and institute's application technology principle.It will be appreciated by those skilled in the art that
The invention is not restricted to specific embodiment described here, can carry out for a person skilled in the art it is various it is obvious change,
Readjust and substitute without departing from protection scope of the present invention.Therefore, although the present invention is carried out by above example
It is described in further detail, but the present invention is not limited only to above example, without departing from the inventive concept, also
Other more equivalent embodiments can be included, and the scope of the present invention is determined by scope of the appended claims.
