Q:What is the role of the pebbles in the transformer base
Transformers base need a pool around the pool inside the pebbles, the role of the pool called the reservoir, that is, when there are accidents, transformer oil leakage, the pool can store oil to prevent the oil flow everywhere, the pool filled with pebbles, in order to Safe, on the one hand is to prevent oil burning. As well as for the convenience of the transformer body above, the following is better than a deep pit convenient? Transformer oil pit volume is calculated in accordance with the transformer oil, there is a certain depth.
Q:Inverter with transformer and transformer without the difference
Select the inverter, then the election from the output waveform, preferably not lower than the quasi-sine wave; Secondly, the inverter should have a complete circuit protection; third, manufacturers have a good after-sales service commitment; And the product after a period of time.
Q:How many transformers are used in a hundred households?
Depending on the specific use of electrical power. First select the rated voltage of the transformer. The voltage on the high voltage side is equal to the voltage of the connected grid. The voltage on the low voltage side is 10% or 5% higher than the voltage of the low voltage side (depending on the voltage level of the transformer and the magnitude of the impedance voltage). Calculate the size of the load carried by the transformer (requires the maximum statistical load, the conversion of the operating load kW value into apparent power kVA). If two transformers are used, the capacity of each transformer can be selected according to 70% of the maximum integrated load. The transformer should be considered for the total load and leave the appropriate margin. Other brand name parameters can be combined with the appropriate consideration of the transformer product. For example: select 35 / 10kV transformer. Assuming a maximum load of 3500kW, power factor of 0.8, choose two transformers, capacity S = 0.7 × 3500 / 0.8 = 3062kVA, 3150kVA transformer can choose, the voltage ratio of 35kV / 10.5kV. Select the model from the catalog.
Q:Is the transformer a power adapter?
Power adapter is a transformer, it should be said that the power adapter is a transformer, rather than that the transformer is a power adapter. Like Baidu is the site, the site is not Baidu ah.
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:Transformer parameter interpretation
C, rated current (A): transformer in the rated capacity, allowing long-term through the current. D, no load loss (kW): when the rated frequency of the rated voltage applied to the end of a winding, the other winding open when the active power. And the core silicon steel sheet performance and manufacturing process, and the applied voltage. E, no-load current (%): When the transformer in the rated voltage under the secondary side of the load, the current through a winding, generally expressed as a percentage of the rated current. F, load loss (kW): the transformer secondary winding short circuit, in a winding rated tap position into the rated current, then the power consumption of the transformer. G, the impedance voltage (%): the secondary winding of the transformer short circuit, in a winding slowly increase the voltage, when the secondary winding short-circuit current equal to the rated value, then the voltage applied once the general. As a percentage. H, the number of phases and frequency: three-phase beginning to S said, single-phase start with D said. China's national standard frequency f is 50Hz. Foreign countries have 60Hz (such as the United States).
Q:How to use transformer 10 in DC circuit
Switching power supply is the use of modern power electronics technology to control the switch on and off the time ratio, to maintain a stable output voltage of a power supply, switching power supply generally by the pulse width modulation (PWM) control IC and MOSFET composition. With the power electronics technology development and innovation, making switching power supply technology is constantly innovating. At present, the switching power supply to small, lightweight and efficient features are widely used almost all of the electronic equipment, electronic information industry is the rapid development of an indispensable power supply.
Q:How do I select a transformer connection group?
Connection group can not be arbitrarily selected, depending on the primary transformer connection group. If the higher-level transformer for the star angle, the next level on the election star angle
Q:How is the transformer sorted?
2, according to the cooling method points: 1) Dry-type transformers: rely on air convection for natural cooling or increase fan cooling, used for high-rise buildings, high-speed toll stations and local lighting, electronic circuits and other small-capacity transformers. 2) oil-immersed transformers: rely on oil as a cooling medium, such as oil from the cold, oil-cooled, cold water, forced oil circulation. 3, according to the use of points: 1) power transformers: for power transmission and distribution system of the rise and fall voltage. 2) instrument with transformers: such as voltage transformers, current transformers, for measuring instruments and relay protection devices. 3) test transformer: to produce high pressure, the electrical equipment for high pressure test. 4) special transformers: such as electric furnace transformers, rectifier transformers, adjust the transformer, capacitive transformers, phase-shifting transformers.
Q:The specific steps and procedures for installing the transformer
Oil-immersed or dry-type transformers are generally installed by the engineering team or factory installed do not know how much capacity your transformer is electronic or industrial power system
