Product Description:

1. Product Description:

ZS, ZSF,ZSZ, ZSG series rectifier transformers are widely used in controlled siliconrectifier power supply and silicon rectifier power supply. They are mainly usedin aluminum, magnesium and zinc smelting, nitric acid, chemicals, pesticides production,electrolysis, electroplating, and traction etc.
There is electrostatic shielding between primary and secondary coils (networkside to valve side) can be electro statically shielded.

The rectifier transformer with two secondary windings and phasedifference of 30°, 15°, and ±7.5 ° for 6-phase and 12-phase rectification canbe designed and produced for users.

Q:5V to 170V Transformer?
Q:Why do people use transformers?
Transformers do one of two things; they either step down the voltage and increase the amperage or they step up the voltage and decrease the amperage. They do this to modulate the line current. They are also usually part of a circuit that creates electricity; to smooth out the flow of current (like in your wind turbine example). Voltage along the primary line in the US is usually at 220 volts and that is to high to use in a house so it is stepped down to 110 volts and sent along secondary lines to homes and businesses. That is done by those big transformers you see in the back yard or hanging off of telephone and power poles. The reason why 220 volts are carried through the main line is to make it transmit further distances before another transformer is required to step up the power to keep it flowing through the line. Most household electronic equipment use a transformer to step the voltage down or up to the levels needed (usually down). The voltage running into the house is too high for most modern TV sets, computers, VCRs and DVD players as well as other stereo components so it has to be stepped down. This also gives the circuit more amperage (more power so to speak) so that it draws less amps from the main circuit and can do its job like spinning motors that take a lot of power.
Q:Wire sizes in the interior of transformers?
The transformers are wound using machinery that can bend the heavy wire as required. Parallel wires are used, but they are not usually tiny, but smaller that what would be needed for single wires. Transformers are wound with flat strap-like conductors rather than round wires. Liquid cooling allows the maximum current in a given size wire. PS Not everything described is used for every large transformer. Construction techniques vary. There may be other techniques and designs used also.
Q:440 primary 220 secondary transformer question clarification?
transformers can either be step up or step down, it will surely work.
Q:New on the transformer reported to stop, how to do,
First, if it is the implementation of non-industrial nature of electricity, there is no need to apply for stop procedures, directly out of the transformer on it.
Q:Why does the transformer have three lines
There are three lines is normal, because in addition to a line of fire a zero line, there is a ground wire (ground wire is directly connected to the Earth's line, it can be called a safe circuit, dangerous when it put high pressure directly To the earth, be a lifeline. 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 use can be divided into: power transformers and special transformers.
Q:10 (6) /0.4kv three-phase transformer what does it mean
Three-phase five-column core transformer must be used YN, yn0, yn0 connection, in the transformer must be connected into the angular connection of the fourth winding, it is not out of the beginning (the structure to do the electrical test when the lead is not This case). 5). When the transformer of different connection group is running in parallel, the general rule is that the connection group label must be the same. 6). When the distribution transformer is used in the multi-mine area, the Yzn11 connection method can be used. When the z-connection method is adopted, the impedance voltage algorithm is different from the Yyn0 connection method, and the copper consumption of the z-way winding is more. Yzn11 connection distribution transformer lightning protection performance is better. 7). Three-phase transformer with four volumes when the core frame can not be used YNy0 connection. 8). These are used for the domestic transformer connection, such as the export should be required to supply the appropriate connection and connection group label. 9). Generally in the high-voltage winding are connected with the tap-changer. Therefore, when selecting the on-load tap-changer (including the on-load tap-changer and the off-circuit tap-changer), it must be noted that the transformer connection and the on-load tap-changer (including connection, test voltage, rated current, Level voltage, voltage range, etc.). YN connected to the on-load tap-changer used on-load tap-changer, it is also important to note that the midpoint must be able to lead.  The answer is recommended by the questioner
Q:why transformer draws lagging current in summers?
The transformer itself is inductive, as others have said, so it will always appear as a lagging load. Now, in the summer, most people are using their air conditioning systems, which are quite inductive because they're essentially just motors. So, the load attached to the transformer could be a good bit more inductive than in other seasons.
Q:How much power loss is in a 120/240V transformer?
It is only about 5 to 10 per cent power loss and the range of efficiency is 90 to 95 per cent.
Q:1000KVA transformer power loss is how much
It depends on its kind of transformer oil-immersed transformer or dry, 1000KVA dry-type transformer no-load loss of about 1.5% to fill the load loss of 3%, oil-immersed transformer no-load loss of about 3% to fill the load loss of 5% The above is just for reference, because each manufacturer has a difference.
