2. General

With the advanced technology brought in from overseas, we developed SC9SCB9 series and SC10SCB10 series padding thin-insulation dry-type distributing transformer whose winding is sealed up with epoxy, therefore the resin insulating dry-type transformer is flame-retardant, explosion-proof, free from maintenance and pollution, and it is compacted and can go deep into load center, besides, with scientific and reasonable design and coating craft work, it has advantages of low partial discharge capacity, low noise, good heat dispersion and it can run over a long time with 125% rated load in the circumstance of cold wind. It applies intelligent thermal controller and has the functions that it will alarm when there is fault or the temperature is exceeded and switch off as the function of black box. It can be monitored and controlled by connecting it to the computer through its RS485 serial interface.

Therefore, it is widely used in the places such as hotel, restaurant, airport, power plant, hospital, skyscraper, shopping center, and residential areas and other adverse environments like subways, smelt and power plant, ship, offshore drilling platform, etc.

Q:What is the vacuum impregnation of the transformer?
so that the transformer immersed in vacuum under the conditions of the paint, so you can rule out the bubble inside the winding, increase Insulation performance. Dip out after drying.
Q:What is the primary side of the transformer
Step-down transformer: primary side of the high-pressure side (primary side) Secondary side refers to the low side (secondary side) Boost transformer: primary side of the low side (primary side) Secondary side refers to the high pressure side (secondary side)
Q:What is the unit of the transformer?
Power transformer capacity unit with KVA, that is, as the power. Most of the power load is inductive load, its apparent power is equal to the sum of active power and reactive power vector. Therefore, the apparent power of the inductive load is greater than the active power. If the active power transformer, the apparent power of the inductive load is greater than the power transformer capacity, the load current to exceed the allowable value of the transformer, so the inductive load must use the apparent power transformer. If the transformer load is all the resistance load, the total power can be equal to the transformer KVA value.
Q:Transformers have any way of cooling
Transformers commonly used cooling methods are the following:   1, oil immersion (ONAN);   2, oil-immersed air-cooled (ONAF);   3, forced oil circulation air cooling (OFAF);   4, forced oil circulating water cooling (OFWF);   5, forced to guide the oil circulation air cooling (ODAF);   6, forced to guide the oil circulating water-cooled ODWF).
Q:Is the LTC transformer a regulated voltage transformer?
Is a voltage regulator. Transformer (Transformer) is the use of electromagnetic induction principle to change the AC voltage of the device, the main components are primary coil, secondary coil and core (core). The main functions are: voltage conversion, current conversion, impedance conversion, isolation, voltage regulator (magnetic saturation transformer) and so on. According to the purpose can be divided into: power transformers and special transformers (electric furnace change, rectifier, frequency test transformer, voltage regulator, mine transformer, audio transformers, IF transformers, high-frequency transformers, impact transformers, instrument transformers, electronic transformers , Reactors, transformers, etc.). Circuit symbols commonly used as the beginning of the number. Example: T01, T201 and so on.
Q:What are the transformer capacity?
The size of the transformer capacity, usually based on the required power supply unit to determine the size of the power supply, with the voltage level is different, the voltage level product capacity is not the same. Voltage levels from 10KV ~ 1000KV range. The conventional capacity starts at 10KVA, and as the voltage level increases, the capacity increases accordingly. For example: 10KVA / 10KV, 500 / 10,2000 / 35,31500 / 66,40000 / 110,100000 / 220,240000 / 330,400000 / 500 and so on (due to too many types, but also the unconventional capacity of the transformer so Can not be simple summary).
Q:Transformers are divided into several. What is the role of each? To be specific!
Transformer is the instrument that regulates voltage! Transformers can be classified according to their operating frequency, use and core shape. (1) Classification by operating frequency Transformers according to the operating frequency can be divided into high-frequency transformers, IF transformers and low-frequency transformers.
Q:Transformer rated capacity 500 / 750KVA (AN / AF) What does it mean?
Air cooling can improve so much no sure no problem, and now a lot of transformer air cooling and self cooling ratio is 100: 80, 100: 70, there are 100: 60.
Q:What is an isolated ring transformer?
Isolated ring-type transformer is mainly focused on its insulation performance, between the primary and secondary must have a double insulation, so that the isolation of its own high efficiency, effective protection of equipment safety.
Q:What is the reactive power compensation of the transformer?
Transformer reactive power compensation is to compensate for the transformer to form the power required by the electromagnetic field, the reason why called reactive power, because it is only exchanged, not consumed. Reactive and active in fact have the same physical properties, in the transmission and use of the process is not part of what is active, that part is reactive. But they are different, there must be other forms of power to be able to transform, no power is not needed.
