Q:630 kilovolt transformer secondary side of the current is how much
There should be a second test voltage to calculate the current, but generally no load 400V. Full load 380V. Primary side rated current: I = 630000 ÷ 10000 ÷ 1.732 = 36.37A Secondary side rated current: I = 630000 ÷ 400 ÷ 1.732 = 909A Maximum output power P = 630 * 0.95 = 599KW (COS ¢ by 0.95) The maximum output power P = 630 * 0.9 = 567KW (COS ¢ by 0.9)
Q:What is the use of the lower part of the transformer made of rail?
This approach facilitates the handling and installation of the transformer, but due to the large and larger transformers, the use of wheels is already less. Transformer The lower part of the box has two structures: (1) Set the wheels, which requires the installation of the track on the basis of the transformer, and then the wheels fixed on the I-beam track, this way to facilitate the maintenance and installation of the transformer handling, but because of the large and larger transformers, the use of wheels Has been less; (2) set I-beam or channel as a load-bearing beam. This transformer does not need to set the track, on the basis of the transformer relative to the location of the beam weighing embedded flat steel, the transformer in place after the load-bearing beam fixed fixed on the base embedded parts. Need to move the transformer, the chisel spot welding, with the hoist and other machinery will slowly drag the transformer.
Q:Altium designer DXP transformer in the same name how to change?
The same name is a painting of about 2-3mil radius of the solid circle, can not directly change, must be copied from the source file to the schematic library file can be changed, that is, to re-create schematic symbols.
Q:Transformer voltage range of 10.5 ± 2 * 2.5% kV and 10.5 ± 5% kV What is the difference
1, the voltage range is the same, are 10kV ± 5%; 2, the difference is that the accuracy of different voltage regulator, 10.5 ± 2 * 2.5% kV transformer sub-switch has five stalls, respectively, 10.5 +5% kV, 10.5 + 2.5% kV, 10.5kV, 10.5-2.5% , 10.5-5% kV; and 10.5 ± 5% kV transformer section switch has three stalls, respectively .5 +5% kV, 10.5kV, 10.5-5% kV; 3,10kV transformer sub-switch three more for the power failure regulator transformer, and sub-section switch five for overload regulator of the transformer, relatively speaking, the fifth gear than the third gear section switch Much more complex, so the price should be slightly higher for the load change is relatively large, the voltage quality requirements of the relatively high important occasions.
Q:What is the meaning of the high voltage side and the low side of the transformer?
High voltage side called high side of the low voltage side called low side
Q:Can a transformer make a small voltage change?
Small voltage can become large voltage. If only in the theoretical considerations, as long as meet the N1
Q:50KVA transformer each phase current maximum band
Normal current does not exceed 72A per phase current. Of course, in the event of an accident or to strengthen the transformer cooling can be short-term overload operation.
Q:220 volts to 24 volts transformer 20a is how many watts
The basic number of watts is the secondary side voltage x current that is 24 x 20 = 480 W. In fact it should be said that the voltammetry (VA) Rigorous argument P = EI cosθ, where cosθ is the power factor, if the power factor of 0.85, then P = 24 X 20 X 0.85 = 408 watts.
Q:The difference between the reflection impedance of the ideal transformer and the hollow core transformer is different.
The ideal transformer reflection impedance is the equivalent impedance of the load resistance equivalent to both ends of the primary coil, directly across the primary coil at both ends, in parallel with the primary circuit, and the nature of the reflection impedance and load impedance of the same nature.
Q:Transformer depreciation period is not specified?
Article 60 In addition to the provisions of the financial and taxation departments of the State Council, the minimum years for calculating depreciation shall be as follows: (A) houses, buildings, for 20 years; (B) aircraft, trains, ships, machinery, machinery and other production equipment for 10 years; (C) with the relevant utensils, tools, furniture, etc., for 5 years; (D) aircraft, trains, ships other than the means of transport for 4 years; (E) electronic equipment for 3 years. Tax law and the provisions of the age is basically the same is not a big difference, but the provisions of the tax law more intuitive Your company can choose according to the above I think is (b) The above is the minimum depreciation period stipulated by the enterprise. The enterprise can choose the appropriate depreciation period according to the actual situation (not lower than the minimum standard stipulated in the tax law). But not to say that the enterprise can arbitrarily extend the depreciation period according to the "hundred years" requirement to depreciate because it is compensation tax The shortest possible time to recover the expenditure to enhance the taxpayer's operating capacity
