Q:What is the maximum current of the 800KVA transformer? What is the current? Is how to calculate, ask you master
This type of capacity of the transformer for the distribution transformer, that is, step-down transformer. Voltage combination to 10 / 0.4 for multi-purpose. Transformer high side current 46.19A, low side current 1154.73A. Rated capacity = 1.732 * rated voltage * rated current
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:The difference between transformer power kva and kw
Kva is apparent power, KW is active power. inspecting power: S = 1.732UI = 1.732 × 0.38 × 100 ≈ 65.8 (Kva) Active power: P = 1.732UI cosφ = 1.732 × 0.38 × 100 × cosφ
Q:Does the production transformer require 3C certification? Does the country have any specific requirements?
The so-called 3C certification "China Compulsory Certification" Is China's mandatory product certification referred to. If your company's products can be sold publicly, without the need for 3C certification, it does not require mandatory certification.
Q:Can dry transformers and distribution cabinets be placed in the same room?
Dry transformers and power distribution cabinets can be placed in the same room. Oil-immersed insulation with insulating oil, dry type with resin insulation, dry-type safety is better than oil-immersed transformers. In the event of a fire or explosion, oil-immersed insulating oil may increase the risk of accidents, so need to be set separately, and the transformer base should have oil leakage design. And dry type change will not have such a danger, it can and power distribution cabinet set in a room, while dry-type transformers and distribution cabinets in the same room easy to overlap, busbar and cable consumption on the reduction, operation and maintenance More convenient, articulated ground and check the power outage when the glance.
Q:Transformer cooling method AN stands for what
The cooling mode of the transformer is determined by the cooling medium and the circulation mode. Dry-type transformer cooling method is divided into natural air cooling (AN) and forced air cooling (AF); oil-immersed transformers commonly used cooling methods are generally divided into three types: oil-immersed self-cooling, oil-immersed air-cooled, forced oil circulation.
Q:What is the main purpose of the transformer?
When a sinusoidal alternating voltage U1 is applied across the primary coil, there is an alternating current I1 in the conductor and an alternating magnetic flux ф1 is generated which forms a closed magnetic path along the core through the primary and secondary windings. The mutual inductance potential U2 is induced in the secondary coil, and ф1 also senses a self-inductance potential E1 on the primary coil. The direction of E1 is opposite to that of the applied voltage U1, which limits the size of I1. In order to maintain the existence of magnetic flux ф1 need to have a certain power consumption, and the transformer itself has a certain loss, although the secondary load is not conne
Q:How do I select a transformer connection group?
Both transformers are center-point direct-to-ground transformers. Dyn11 wiring group of the transformer because of its high-voltage winding is triangular wiring, so when the user produces three and three times the harmonic, can be formed in the triangular winding circulation, resulting in magnetic flux to eliminate this harmonic pollution for the grid. The Yyn0 transformer because there is no triangular winding, without this function. If only an independent power supply of small capacity transformer, you can use Yyn0 transformer, such a transformer everywhere, good production. If there is a transformer that may be supplied in parallel with other transformers, or as a backup power source for other power supplies, the same wiring group as other transformers should be selected. If it is recommended for large-capacity industrial transformers Dyn11 transformers are recommended to reduce the contamination of the grid by three or three times the number of harmonics.
Q:How much capacity the transformer has
According to GB / T6451- "three-phase oil-immersed power transformer technical parameters and requirements", the voltage level 10kV-220kV, the capacity is as follows (kVA): 30,50,300,123,80,100,125,160,200,250,315,400,500,630,800,1000,1250,1600,2000,2500,3150,4000,5000,6300,8000,10000, Lt; / RTI & gt;
Q:Transformers of the three transformations are the three?
Do not know you specifically refers to the meaning, in general, the transformer can change the voltage, variable current, variable phase
