50 kva transformer to adopt new technology, new technology, effectively reduce the no-load loss and load loss, at the same time performance conforms to the standard, has a long service life, small footprint, low temperature, good heat dissipation, the characteristics of safe and reliable, can be widely used in power plants, power stations, industrial and mining enterprises, such as user distribution substation below 35 kv power and power distribution system.Maybe it can help you.

 

 

Daelim Transformer is a professional transformer supplier located in China. The professional technical team can design a 50kva transformer that fully complies with ANSI/EEE, DOE, CSA, AS/NZ, and other international standards. It has SGS, CESI, IEEEC 57, IEC60076, CSA C88, and other transformer test reports, as well as UL, and cUL certificates.

 

what is a 50 kva transformer ?

Generally speaking, the unit of transformer is KVA. The transformer is 50 kVA, that is to say, now this transformer is 50 kVA and notice the apparent power. KVA = KiloVolt-Ampere

KVA is used as the unit, because it is impossible to get the value of active power and reactive power when the load is not clear. At this time, KVA is used as the unit, which usually represents the apparent power, symbol S.

 

Transformer 50kVA is the capacity of the transformer, the power factor of the general transformer is about 0.85, active power is about 45 kW, can take up about 45 kW electrical appliances.

 

How much load can a 50 kVA transformer handle?

A 50 kVA transformer can load 35~50 kW

VA is the unit of apparent power S, W is the unit of active power P, P=S*COS, COS is the power factor, 50KVA transformer means that it can withstand 50KVA load, but the power factor is unknown, assuming that the low-voltage section does not compensate, power factor 0.8, the transformer can take 50*0.8=40KW, if the low-voltage section has no power compensation, After compensation power factor 0.95, that can take 50*0.95= 47.5kW.

From the operation observation, no matter how much load, as long as the temperature of the transformer is slowly rising, the temperature does not exceed 85 degrees, can operate normally.

 

Equivalent aging principle of transformer: Equivalent principle of aging is the transformer windings in a part of the run time temperature lower than 95 ℃ or less load, in another part of the time can make winding temperature higher than 95 ℃ or overload, just make more loss is equal to the life of a transformer overload time less loss of life in owe load time, the two cancel each other out, can still maintain the normal service life.

 

Transformer insulation aging six degrees principle: when the transformer winding insulation temperature in the range of 80 ~ 130℃, the temperature rises 6℃, the insulation aging speed will increase twice, that is, the temperature rises 6℃, the insulation life will reduce 1/2, this is the "six degrees rule" of insulation aging.

 

Cannot run if:

1) The temperature rises rapidly and soon exceeds 85 degrees.

2) There is smoke inside the transformer.

3) There is a crackling sound.

3. How many houses can a 50 kva transformer supply ?

 

Most all-electric homes in the U.S. have 200A service, though they rarely need that much at any given time. A four-bedroom 2,300-square-foot house, for example, uses about 50 KWH per day or 1,500 KWH per month. I would say it's typical.

 

But for 240VAC 200A service, that's 48kVA, so a 50 kVA transformer can power only one home. However, at 1500 KWH/month or 50 KWH/day or 2.083 KWH/hour or average 2.083 kVA. But that's the average. I would say it could be up to 5 times or 10kVA at a time, so a 50kVA transformer can power 5 homes.

 

50kVA transformer types

50 KVA transformers can be divided into single phase pole mounted transformers, single phase pad mounted transformers, and dry-type transformers.Here we introduce the single phase pad mounted transformer in detail.

We introduce DAELIM ANSI/IEEE single phase pad mounted transformer, capacity 50KVA, high voltage rating should be 7200V, low voltage rating should be 480/240V.

 

50kVA Transformer features

Single phase pad mounted transformer fully sealed, fully insulated, safe and reliable, small volume, compact structure, beautiful appearance, volume is only about 13 of the box type substation (European type box transformer).

Double fuse full range protection method, greatly reduce the operation cost. Cable head can be live operation, has a strong overload capacity. The box body is treated with special technology and has good anticorrosion ability.

10kV bushing cable head can be inserted and removed in 200A load current for many times, and used as a load switch in emergency situations, and has the characteristics of isolation switch. The use of high ignition point oil, eliminating fire hazards,

Adopt domestic 9 type, 11 type distribution transformer, low loss, low noise, long service life.

 

50kVA Transformer Application places

No power distribution room can be directly placed in the indoor or outdoor, also can be placed on both sides of the street and the green belt, reliable to ensure personal safety, both power supply facilities, but also decorate the environment.

Can be used for terminal power supply and ring power supply, conversion is very convenient, to ensure the reliability and flexibility of power supply.

 

50kVA Transformer accessories

High voltage plug and pull fuse, backup fuse, low voltage circuit breaker, pressure release valve, oil level gauge, oil injection valve, tap switch, load switch, etc.

 

How big is a 50 kVA transformer?

Most all-electric homes in the U.S. have 200A service, though they rarely need that much at any given time. A four-bedroom 2,300-square-foot house, for example, uses about 50 KWH per day or 1,500 KWH per month. I would say it's typical.

I would say it could be up to 5 times or 10kVA at a time, so a 50kVA transformer can power 5 homes.

 

How much does a 50 kVA transformer weight?

 

50KVA distribution transformer, generally copper coil, S9 series transformer weight is about 360 kg, and S11 fully sealed series transformer weight is about 440 kg.

 

Different types of 112.5kva transformers have different weights.

• The weight of 50KVA single phase pole mounted transformer is about 395kg.
• The weight of 50KVA single phase pad mounted transformer is about 553kg.
• The weight of 50KVA three phase pad mounted transformer is about 550kg.

 

How much does a 50 kva transformer cost?

50 kva price is determined by the different types of transformer, voltage, frequency, connection type, cooling type, impedance, no load loss and full load loss, NLTC and OLTC, power frequency withstand voltage and lightning impulse withstand voltage of these are the factors influencing the price of transformer is very important, we can not directly answer here.
