Abstract
The utility model provides a marine power transmission system constructed on ships such as container ship for transmitting power on ships or shore comprises a high-voltage shore-side connection box, a transformer, a high-voltage connection box, a low-voltage connection box, an automatic switcher, a process controller, a distribution panel of freezing container, a main distribution panel, and a transducer. When the ship reached shore, the high-voltage cable transmits shore power to the system; and the automatic switcher sequentially switches the power supply system of freezing containers from ship power to shore power according to commands from the process controller and supply the system to the distribution panel of freezing container. At the same time, a portion of motors on ship is stopped due to the reduced load of the ship power and only one motor supplies power to the main distribution panel. When the main distribution panel is connected with shore power, ship power can be parallelly connected with the shore power in a second, and the working motors are switched off while the ship is supplied by the shore power.
Description
Technical field
The utility model relates to a kind of maritime affairs electric power for communication system, refer in particular to a kind of traditional system of relying on the ship power generating fully that is different from, can native system when boats and ships pull in to shore the supply of coupling bank electricity, and in the process of electric power system conversion, avoid cause the harm of instantaneous variation such as system on transformer, generator or other ship with the lightest load.
Background technology
Boats and ships comprise fixed pollutant sources, portable pollutant sources and combustion air pollutant sources to the pollutant sources of air, when resting against harbour, boats and ships belong to fixed pollutant sources, boats and ships belong to portable pollutant sources when navigation, the dynamical system of boats and ships then belongs to the combustion air pollutant sources.Because of the air pollution source that boats and ships produced mainly can be divided: dust and foul smell air pollution that boats and ships are produced when loading and unloading goods; The pollution of the exhaust that produces when diesel engine and boiler combustion in the ship power system.Guaranteeing that the earth can survival, has not been the responsibility that a few peoples should bear, but lives in this everyone obligation and responsibility, certainly, comprise boats and ships and boats and ships everyone can not place oneself in the midst of outside the thing.
Electricity needs on the container ship, comprise refrigerated enclosed container system and general using electricity system, all be by the supply of house generator group, the power source of these generating sets is exactly a power of relying on boats and ships, particularly after boats and ships pull in to shore, in order to keep the electric power of generator, must be with the diesel engine continuous running, because the merchandise-chest-quay activity duration is longer, the air pollution that is caused certainly will produce great influence to firmly people's livelihood quality alive on the bank.
The utility model content

Have more and more and fact proved; the device of feed and distributor breaker and insurance protection has been difficult to the protective effect that reaches real to solid state electronic devices; these devices may be ruined by the instantaneous variation of utmost point short time, and this instantaneous variation mainly is revealed in the following aspects to the harm of power consumption equipment:
One, to electronic equipment;
Electronic equipment runs into instantaneous variation a lot of situations can occur, and first kind of situation is that described equipment is interfered, and causes on the display screen data corruption or system by deadlock, and this may cause the puzzlement of operation, but usually can damage equipment.Second kind of situation is to make the equipment accelerated ageing, and be frequent if the instantaneous variation effect is quite fixing, comes across the whole cycle as pulse, and system component will accelerated ageing as power rectifier or integrated circuit package.Then producing the third situation, is exactly the breaking-up of assembly, and when the equipment somewhere begins to smolder or sends the sound of similar explosion collapse, this just means, and big danger will take place.
Two, to motor;
Instantaneous variation can influence motor in several modes, and the first, if motor is an Electronic Control, then to the spike sensitivity.The second, generally to standard electromotor, spike acts on winding, stator winding often generates heat because of instantaneous variation absorbs energy, the energy of apparent absorption what and decide, will cause the insulation decline or the abolish of winding, behind insulation breakdown, the phenomenon that motor will be short-circuited or burn.
Three, to lighting system;
To incandescent lamp system, the effect of instantaneous variation will cause filament blow, bulb break.To standard fluorescent lamp system, spike has two kinds of influences, and the first, the rectifier intraware damages and damages, the second, if spike is boosted by internal transformer to being enough to slowly, its crest voltage will cause fluorescent tube to damage, at this moment, can see that fluorescent tube is glittering momently, burn out subsequently.
Therefore, because electric power can be fully supplied with by the bank electricity on the ship of the present utility model, therefore can stop the dynamical system of boats and ships and reduce the air pollution source that burning produces; Because of having only the more or less freely and safety of generator operation in the operation, and can guarantee not cut off the power supply on the ship, and load is less, can not impact to transformer, in like manner, when the bank electricity is converted to the supply of ship electricity, also can not cause the harm of instantaneous variation, be principal character of the present utility model system on generator or the ship.
Outside above-mentioned, electric power of the present utility model also has following characteristic for communication system, has futurity, elasticity, fail safe, high reliability, low-risk, ease for operation and easily maintenance property, describes in detail as the back:
One, system design is by three groups of die casting transformer-supplied, and for 50/60Hz shares, two groups are installed on about boats and ships two side of a ship coolings and freeze the counter system and use, and one group is installed in the cabin for General System use on the ship; Described die casting transformer has characteristic dustproof and that exempt to maintain, even after long-time the stopping using, and the use of also can in time powering.
Two, the utility model can be assembled into one with high pressrue connection box, transformer and low pressure junction box, in order to installation.
Three, be loaded with programmed logic control (PLC) system in the refrigerated enclosed container feeder panel of the present utility model, can power in proper order to the refrigerated enclosed container system according to setting, to reduce impact, to guarantee transformer's life span and fail safe to transformer.
Four, when on the ship during unloaded refrigerated enclosed container, the refrigerated enclosed container dedicated transformer of then can stopping using is with the waste that reduces electric power and the cost of operation.
Five, when a certain refrigerated enclosed container dedicated transformer fault, then can provide sub-load, to reduce goods damage by the transformer of general usefulness.
Six, electric power of the present utility model is equiped with frequency converter for communication system, applicable to the demand at each different harbours, the following whole world.
The foregoing description only is used to illustrate the utility model, but not is used to limit the utility model.
