Product Description:

110kV Oil-immersed Power Transformers


1.    Introduction

Oil immersed power transformers designed and manufactured by us is based on advanced technologiesand rich experiences.  The products have been improved in the design, structureand processes, with good resistance to short circuit capacity, good mechanical properties, lower partial discharge, low noise, no leakage, beautiful appearance, easy maintenance etc.



2.   Service

Altitude: <1000M ( can be adjusted according to customer requirements)

Maximum environmental temperature: +40 ℃, Minimum environmental temperature: -40 ℃ (can be adjusted upon customer’s request)

Maximum wind speed: 36.2m / s

Relative humidity: 90%

Earthquake intensity: seismic acceleration (horizontal and vertical component take effectsame time)  transformer can withstand seismic forces of 8 Richter scale earthquake.

Contamination level:  3

Q:10 (6) /0.4kv three-phase transformer what does it mean
Therefore, the decision to 60 and 35kV winding connection to be careful when the connection must meet the transmission system voltage phasor requirements. The connection between 60 and 35kV windings is determined according to the relative relationship of the voltage phasors. Otherwise, even if the capacity of the voltage ratio is also right, the transformer can not be used, connected wrong, the transformer can not be connected with the transmission system. 3). Domestic 10,6,3 and 0.4kV transmission and distribution system phase also has two phases. In the Shanghai area, there is a 10kV and 110kV transmission system voltage phase difference of 60 ° electrical angle, this time can be used 110/35 / 10kV voltage ratio and YN, yn0, y10 connection three-phase three-winding power transformer, but limited Three-phase three-core core. 4). But note that: single-phase transformer in the combination of three-phase group connection, can not use YNy0 connected three-phase group. Three-phase shell-type transformer can not use YNy0 connection.
Q:What are the transformer capacity?
Transformer capacity: 15,30 50 63 80 100 125 160 200 250 315 500 630 A high - speed range of 12500 .. The The The The (Unit: KVA) Small is less than 1600KVA Medium 1600--6300KVA Large 8000 - 63000KVA Extra large is greater than 63000KVA
Q:Why is the transformer coil insulation?
It is easy to understand because the transformer is used in different environments, according to different insulation level selection, can extend the life of the transformer
Q:Can dry transformers and distribution cabinets be placed in the same room?
Yes. Dry-type transformers are usually placed in the room with a shell, low-voltage cabinet is with the dry-type transformers together. The general practice is to flush the cabinet. And then connect the transformer with the low voltage cabinet directly in the cabinet to go. Outside can not see the connection of copper.
Q:What is the unit of the transformer?
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:315KVA transformer high-voltage side need to use the specifications of the high-voltage cable
315KVA transformer high-voltage cable 50 square how much, but in accordance with the local power supply from the power supply program to set, not how much is their own
Q:The difference between the reflection impedance of the ideal transformer and the hollow core transformer is different.
The reflection impedance of the hollow core transformer reflects the influence of the secondary circuit on the primary circuit through the mutual inductance. The reflection impedance is in series with the self-impedance of the primary circuit. The reflected impedance of the air-core transformer is opposite to the reactance characteristic of the secondary circuit impedance.
Q:220 kv transformer capacity range,
Oil-immersed power transformer is one of the company's leading products, the original Ministry of Machinery Industry planning in Shandong Province, 220kV and below the production of the only key power transformers. Product voltage level 6 ~ 220kV, capacity 30 ~ 360000kVA, including 23 series, more than 200 varieties, more than 1,400 kinds of specifications, the technical performance indicators all meet the national standards and the International Electrotechnical Commission standards. The company has designed and manufactured the first domestic 110-kilovolt 31500 kVA three-coil aluminum transformer. Since the 1982 production of 220kV transformer, the product has been used in sunshine, Taizhou, Jiangxi and many other national key projects
Q:Transformer tap adjustment there are several ways? What are the advantages and disadvantages?
1, no excitation adjustment or no taps. 2, with taps. Their advantages and disadvantages are as follows: 1, no taps: taps when the transformer must be shut down after the power, the advantages of safe and reliable, but the disadvantage is to adjust inconvenient, and often because the tap position can not meet the needs of less. 2, with taps Advantages: easy to adjust, do not have to turn off the transformer power can be adjusted, and the general tap position more easily meet the requirements. Disadvantages: due to load adjustment prone to problems, high cost, compared with the same capacity transformer volume, taps device maintenance needs a long time to blackout.
Q:What is the principle of the conversion of the transformer? How to restore the secondary side to the primary side?
Understand P1 = P2 (no loss here). To know the return of the.
