- Q:Transformer tap adjustment there are several ways? What are the advantages and disadvantages?
- 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:Taiwan, Taiwan, the concept of transformer
- Transformer refers to equipment;
Taiwan change is installed in a place of the transformer, is specifically installed, running a transformer;
Taiwan area refers to the regional range of variable power supply.
Metering point is for the two sides to determine the installation of electric energy meter position, in general, the measurement point should be set at the demarcation point of property rights.
- Q:What is a transformer paused?
- In accordance with the provisions of Article 24 of the Power Supply Business Rules:
The user is suspended and must apply to the power supply company five days ago. The power supply enterprise shall handle the following provisions:
1. In each calendar year, the user may apply for all the temporary (including the high voltage motor that does not pass the receiving transformer) or part of the electricity capacity of the temporary stop power twice, each time not less than fifteen days, one year cumulative pause Not more than six months. Seasonal electricity or other users of the country, the cumulative pause time can be negotiated;
2. According to the transformer capacity of the user to charge the basic electricity, the suspension of electricity must be the whole or the whole group of capacitors to stop running. After receiving the application for suspension, the power supply enterprise shall pay the suspension of the equipment according to the date when the user applies for the suspension. From the date of the seal, according to the original billing method to reduce the corresponding capacity of the basic electricity;
- Q:Which is good for the transformer?
- Recommended Shanghai Zul! Zul (Shanghai) Electric Manufacturing Co., Ltd. is well-known enterprises in China Transformer! Shanghai transformer industry well-known brands, low-voltage dry-type transformers in the field of the leader. The strength of advanced technology, management science. As a well-known transformer, the company's main products are: SGSBK three-phase transformer (imported equipment dedicated transformer, motor-specific transformers, etc.), OSGQZB autotransformer, ZSGZDG rectifier transformer, BKDK control transformer,
- 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:Two different impedance of the transformer, parallel load how to allocate?
- When the impedance voltage is equal, the transformer runs side by side:
Because the transformer load distribution is proportional to its rated capacity, and inversely proportional to the impedance voltage. In other words, when the transformer is running in parallel, if the impedance voltage is different, the load is not proportional to the rated capacity of the distribution, parallel transformer current and impedance voltage is inversely proportional to the II / III = UZKII / UZKII or UZKIIII = UZKIIIII, Set two transformers running side by side, the capacity of SNI, SNII, impedance voltage UZI, UZII, then the load of each transformer according to the following formula:
SI = [(SNI + SNII) / (SNI / UZKI + SNII / UZKII)] * (SNI / UZKI)
SII = [(SNI + SNII) / (SNI / UZKI + SNII / UZKII)] * (SNII / UZKII)
That is, S △ I / SII = (SNI * UZKII) / (SNII * UZKI)
According to the above analysis we can see: When two transformers with different impedance voltage are running side by side, the distribution load with large impedance voltage is small. When this transformer is full load, another transformer with small impedance voltage will run over load. Transformer long-term overload operation is not allowed, therefore, only the impedance of the transformer voltage overload operation, thus limiting the total output power, energy loss also increased, it can not guarantee the economic operation of the transformer. Therefore, in order to avoid the impedance voltage difference is too large, so that the parallel transformer load current distribution is uneven, affecting the transformer capacity can not be fully played, the specified impedance voltage can not be a difference of 10%.
- Q:Can the transformer oil be used as a lubricant?
- Can not! Two kinds of oil indicators out of the thousands of miles out! According to you say with the line also do more money to prepare for the machine! Oh! Looking for compressor oil, general 13 # compressor oil and 19 # Compressor oil! 13 with dilute words on the 19 # must be no problem!
- Q:What is the power transformer, what is the rectifier transformer
- Power transformers generally refers to the power of the Department of power supply transformers, transformers in the power grid are mostly power transformers.
Rectifier transformers are designed for rectifier systems. Rectifier transformer function:
1. is the appropriate voltage to supply the rectifier system,
2. It is to reduce the pollution caused by the waveform distortion caused by the rectifier system.
- Q:What is the meaning of auxiliary transformer, sub-variable and box change
- During the main transformer failure or overhaul, the auxiliary transformer provides the substation's own electricity. Maintenance of substation lighting, high and low voltage switch action, with the cabinet switch operation, for instrumentation and automatic control system work, sub-change can be box change,
- Q:10 (6) What is the meaning of 10 and 6 in the KV transformer?
- These numbers refer to the voltage, 10 (6) KV transformer 10 and 6 refers to the primary side of the transformer voltage level is 10kV or 6kV.
10 / 0.4 (0.22) KV substation in the number of "/" refers to the transformer primary side of the voltage level 10kV, followed by the transformer secondary side of the voltage level is 0.4kV and 0.22kV, that is, 400V And 220V
The primary voltage is the voltage of the transformer line, the secondary voltage is the voltage after the transformer transformer.
