1. Product Description:
Voltage stabilizer is a device which makes the output voltage stable. Regulator with constant voltage, control circuit, and servo motor, etc.. When the input voltage or load changes, the control circuit for sampling, comparison and amplification, then drive servo motor to rotate, and the pressure regulating carbon brush position change, by automatically adjust the number of turns of the coil, so as to maintain the stability of the output voltage.
The fixed output DC regulated power source is composed of isolation transformer, bridge rectifier,large capacity filter power tube of big power modular regulating circuit,protective circuit, it can work continuously for a long time with the function of sufficient output current,small wave,high stability,reliable performance,limited over-current protection and self-recovery.

- Q: Transformer ratio and transformer ratio
- Transformer ratio K and transformer voltage on both sides U1 U2 winding turns N1 N2 current I1 Ⅰ2 have a relationship! In the ideal case, the ratio K = U1 / U2 = N1 / N2 = I2 / I1
- Q: Transformer turns around the number and how much V is calculated
- 2, seeking coil turns Primary coil n1 = 220 ╳ 9.8 = 2156 turns Secondary coil n2 = 8 ╳9.8 ╳ 1.0 = 82.32 desirable for 82 turns 1.05 in the calculation of the secondary coil turns is the pressure drop when a load is considered
- Q: What are the technical parameters of the transformer?
- I, temperature rise and cooling: transformer winding or the upper oil temperature and the temperature difference between the ambient temperature of the transformer, known as the winding or the upper oil temperature rise. Oil-immersed transformer winding temperature rise limit of 65K, oil surface temperature rise 55K. There are a variety of cooling methods: oil from the cold, forced air-cooled, water-cooled, tube, chip and so on. J, Insulation level: Insulation class standard. Insulation level of the method for the following example: high voltage rated voltage of 35kV level, low voltage rated voltage of 10kV level transformer insulation level expressed as LI200AC85 / LI75AC35, which LI200 said the transformer high voltage lightning impulse withstand voltage of 200kV, power frequency withstand voltage For the 85kV, low voltage lightning impulse withstand voltage of 75kV, power frequency withstand voltage of 35kV. Oaks High Technology Co., Ltd. The current oil-immersed transformer product insulation level LI75AC35, said the transformer high voltage lightning impulse withstand voltage of 75kV, power frequency Withstand voltage of 35kV, because the low pressure is 400V, can not be considered. K, the connection group label: According to the transformer one. Secondary winding phase relationship, the transformer winding connected into a variety of different combinations, known as the winding group. In order to distinguish between different groups, often using the clock representation, that is, the high voltage side of the voltage phase of the clock as a long needle, fixed on 12, low voltage side of the phase voltage as the clock short needle, (A) is a (triangular) joint, and the secondary winding is a (star) junction with a center point, and the group number is (11).
- Q: Transformer Lightning
- Dry coil internal coil will burst open, so that the transformer outside the four sides of the shell will be bulging. Cylinders on the porcelain will burn black, porcelain will be black and cracked. The line breaker is tripped.
- Q: My device has 50KW should be used with much transformer
- You can go to the factory to help you under the selection. My company last year in Shanghai elegant power equipment Manufacturing Co., Ltd. to buy several, good quality, good service, you can go to his home under the consultation.
- Q: What is the main purpose of the transformer?
- If the secondary connected to the load, the secondary coil to generate current I2, and thus produce magnetic flux ф2, ф2 and ф1 opposite the direction, played a mutual offset effect, so that the total magnetic flux in the core has been reduced, so that the primary Self-induced voltage E1 reduced, the result is I1 increase, showing the primary current and secondary load are closely related. When the secondary load current increases when I1 increases, ф1 also increases, and ф1 increase part of the part is just to be replaced by ф2 that part of the magnetic flux to keep the total magnetic flux in the core unchanged. If you do not consider the loss of the transformer, you can think of an ideal transformer secondary load power consumption is the primary power from the power supply. The transformer can change the secondary voltage by changing the number of turns of the secondary coil as needed, but can not change the power that allows the load to be consumed.
- Q: Transformer Uk = 4.5% What does it mean?
- The short circuit impedance of the transformer is related to many factors of the transformer. Such as transformer capacity, loss, internal coil structure and so on. But once the transformer is manufactured, it is the same. Short-circuit impedance is a very important technical indicator for the user. Such as the stability of the power supply system, the quality of the power supply, the transformer in parallel after the safety and reliability, and so have a relationship.
- Q: can any one give me a fast time line of transformers history
- The gods Primus and Unicron nearly destroy the universe fighting until Primus tricks Unicron by imprisoning them both in metal planetoids. Unicron becomes giant transforming world devourer and Primus becomes Cybertron, bringing to life the transformer race that will fight Unicron in his stead. The robots of Cybertron eventually begin civil war which go on for millions of years, the evil Decepticons vs the heroic Autobots. Unicron finds Cybertron, the Autobot leader destroys him with the Matrix, the transformers fulfill their destiny. Their war continues until Cybertron is nearly depleted so the planet is reformatted and the race adopt Maximal and Predacon castes. New wars begin until balance is struck and Cybertron becomes technorganic paradise
- Q: hello thank you for reading this question, i have a iron cored dc-ac transformer (relies on interrupter to constantly break circuit to induce induction in secondary coil) a brief and crude diagram can be found
- If I understand correctly, you want to turn an old transformer into an electromagnet, and you want to use both windings in order to get the strongest possible field. First of all, you are going to need to modify the core: It needs a gap. In a perfect transformer, the lines of magnetic force would be entirely confined to the core.
