The invention solves the blindness of ice maker users on line configuration, scientifically, concisely and easily guides the ice maker users to consult and implement the method, and furthest ensures the normal working of the ice maker.
Description
Technical field
The present invention relates to a kind of supply line collocation method, relate in particular to a kind of method for configuring power supply lines of ice maker.
Background technology
Requirement and the of the same trade general requirement basic to electric type device power supply (DPS) voltage, the scope the during work of ice cream machine supply voltage according to IEC, GB near nominal voltage+/-10%, be 198～242V in the China mainland area.Followed this requirement in ice maker design when producing, in fact it is exactly the condition as the ice maker operate as normal: in the ice maker opening process, as if the supply voltage long period not within aforementioned range, can not enter normal operating conditions; During ice maker work, if supply voltage is ineligible, then ice maker will be deactivated and be entered the protection holding state; Have only supply voltage eligible; just can guarantee the ice maker unlatching and carry out operate as normal; the purpose of doing like this is to protect important electric objects such as relay in the ice maker, stirring motor, compressor, thereby guarantees or prolongs the useful life, minimizing preventive maintenance time etc. of ice maker.
Come into the market at ice maker, when the user uses since being not quite similar of power environment, environment for use be not quite similar, dispose being not quite similar of supply line, the power supply circuit that can not guarantee whole ice makers has the mode standard of a unified standard.If the electrical appliance load current is bigger, the configuration state of power supply lines will farthest influence the establishment of supply voltage service condition so.With regard to up-to-date technology, sludge ice mechanism cake amount about 12A, belongs to the bigger electrical appliance of load at the stable state running current of 35 liters of left and right sides main flow single phase poaer supply class types in the market.
General electric power changes distribution center that low tension enter our unit from the power taking of civil power High-Voltage Network through transformer station/institute with electric unit such as community or company etc., is designed to each electricity consumption user for distribution according to building by distribution center and disposes circuit and provide and deliver.This is a kind of way of standard.Single-phase ice maker electricity consumption is in the residential electricity consumption district (as community or shopping centre) generally, belongs to big power consumption equipment (specified input current is at 12A).If it is not enough or do not reserve circuit that the ice maker place is in the distribution design pre-made allowance; so; often just on existing line, compete electric power together with existing electrical appliance; cause degradation under the supply voltage; thereby make ice maker enter the protection holding state; can't start, because the nonstandard parasexuality that ice maker is used, ice maker manufacturer does not also provide a rather effective solution to this technical problem at present.
Summary of the invention

The invention provides and a kind ofly can compare science, guide the ice maker user to consult and carry out clearly, simply, guarantee supply line's collocation method of ice maker operate as normal to greatest extent.
Embodiment
The present invention is further illustrated below in conjunction with embodiment:
Embodiment:
Table 1: power supply lines of ice maker allocation list
Illustrate:
1) table 1 aims at ice maker (single phase poaer supply, sludge ice machine, hard ice maker) configuration, and its cable is at least 3 cores (every core is copper multiply): L phase line+N zero line+PE protective earthing;
2) during the ice maker electricity metering, configuration 20A or above ammeter;
When 3) this area line voltage is difficult for stablizing, should be at the configuration of supply socket place before ice maker 5KVA power regulator.
In the table 1,, please refer to following method and convert if having to add other electrical appliance in the supply line:
With the electrical appliance that adds 1000～1200W is example, at first calculates conversion factor k=1+ and adds electrical appliance gross power/ice maker rated input power=1+1200W/2400W=1.5.Convert corresponding data in the allocation list then, if need the 2nd row of conversion first line segment: when 300 meters of threads were constant, the conversion of cable nominal area of section was 25*k=25*1.5=37.5 (mm
2), can choose 35mm nearby
2Cable; When the cable specification is cable nominal area of section 25mm
2When constant, then the thread conversion is 300/k=300/1.5=200 (m).
Relevant parameter with the sludge ice machine is an example below, in power supply lines, and the corresponding relation of cable thread and cable nominal area of section:
1) Chinese ordinarily resident's voltage standard: 50HZ, 220V;
2) a stage load A level power supply scope: 5% (with respect to above-mentioned voltage standard)
3) join supply line's loss permissible range: 5%;
4) distribution center is to distribution box cable laying smallest cross-sectional: 16mm
2
5) existing sludge ice machine series complete machine maximal input: 2400W considers various losses, surplus etc., presses 5000VA and calculates;
Or maximum input current: the 12A of sludge ice machine series complete machine stable state, for the purpose of safety, calculate by doubling as 24A.
6) dc resistance of general Plastic-sheathed Cable: see electrical technology class reference book.
To supply socket, cable nominal area of section S ' is 6mm with distribution box
2The time, the dc resistance of cable master core is 3.13 Ω/KM, the computational methods of cable thread are: and from the distribution center to the distribution box, from the distribution box to the supply socket, respectively lose 2.5% again, lost for 5% (joining supply line's loss permissible range) so altogether,
Computing formula one: by power is that 5000VA calculates
Cable thread L '=(220V * 2.5%) ÷ (5000VA/220V) ÷ 3.13 Ω/KM=0.0773KM=773M.
Calculate two: by electric current is that 24A calculates
Cable thread L '=(220V * 2.5%) ÷ 24A ÷ 3.13 Ω/KM=0.0732KM=73.2M.
Comprehensive above two kinds of calculating are 6mm for nominal rating as can be seen
2Cable line taking length be no more than 80m, meet the corresponding configuration in the table 1.
Part test measured data of the present invention such as following table:
Table 2: part test measured data table
Table 2 remarks:
(1) civil power refers to the normal voltage 220V/50HZ that power is enough;
(2) voltage stabilizing refers to by power to be each voltage of the pressurizer pressure regulation end output of 5000VA;
(3) the sludge ice machine uses OPF3036/OPF3038 type machine, and ice maker is numbered: 1204030002T#, and normal pressure, room temperature is: 30 ℃.
In order clearly, clearly to see the relation between test data and the calculated data, we sum up in the point that table 1 time with above-mentioned test data:
Cable one: nominal area of section 2.5mm
2, length 100m, steady state voltage line loss average is 10.0V; Sum up in the point that table 1 time, loss voltage U=10.0V/ (100m/30m)=3.00V;
Cable two: nominal area of section 4mm
2, length 100m, steady state voltage line loss average is 5.50V; Sum up in the point that table 1 time, loss voltage U=5.50V/ (100m/50m)=2.75V;
Cable three: the nominal area of section 6mm of one of main core
2, length 100m, steady state voltage line loss average is 2.25V; Sum up in the point that table 1 time, loss voltage U=3.00V/ (100m/80m)=2.40V;
Can be from this, above-mentioned three data are about 2.75V (foundation in the data computation: 5.5V (one section line loss 2.5%)/2 (various losses, the surpluses considered when eliminating aforementioned calculation)=2.75V) all.This joins supply line just and is lost in the magnitude of allowing of not considering to leave surplus.Thereby understand the correct and feasibility of the foregoing description list data in test Shanghai Stock Exchange.
Although the present invention has done to describe in detail and quoted embodiment as proof, for those of ordinary skill in the art, obviously various schemes, modification and the change that can make according to above-mentioned explanation all should be included within the scope of claim.
