Production introduction
Our company has developed this product by ourselves.As a high performance,high safety,pollution free dry-type transformer,it is suitable for the harsh environments where there is a high fire protection requirement,the great load fluctuation and the site where is of filth and moisture.For example:airport,power plant,metallurgy operation,hospital,high building shopping center,densely inhabited ared,petrochemical industry,nuclear power station and nuclear submarine,elc.
Normal service conditions
1.A unique ceramic type of insulation structure is adopted in H-class high strength insulation cylinders and high-frequency ceramic cushion blocks are adopted to ensure that no deformation will occur.
2.The high-voltage and low-voltage windings are made of NOMEX wrapped flat copper wires and imported copper foils.And they are sealed with high strength insulation materials.
3.The iron core is made of laminated imported high-quality silicon-steel sheets of high magnetic conductivity with a 45 stepwise all-bias structure.A flexible fastening unit is adopted to fasten the winding and iron core,which ensures a relatively low no-load loss and low noise.
4.Outlet terminals are fixed to the top of winding,taps are in the middle of winding,low-voltage line terminal are in plate-type current-conducting rows for which cold pressure welding is adopted.

- Q: 50 What is the actual power of the transformer? Is 3 phase 50 or 3 together 50
- Three-phase transformer marked the basic capacity of three-phase capacity, that is, the sum of three-phase winding capacity is 50KVA. The actual output capacity of the transformer, not only with the rated capacity of the transformer has a relationship with the nature of the load, and the power factor of the load, and the efficiency of the transformer has a relationship with the level of loss of the transformer. When the load balance, stability, pressure efficiency of 100%, the actual power can be achieved: P = Se × COSφ, visible higher power factor, the closer to 1, the transformer the actual power is higher, closer to the apparent power. In general, the 50KVA transformer, when the power factor of 0.85, the actual output power of about 42.5KW.
- Q: The book said the main transformer power failure operation should first stop the load side after the power side, is to prevent the transformer in the case of multi-power reverse charging. What is the transformer anti-charging here? What's wrong?
- Here to step-down transformer as an example: The forward power supply is powered by the high side of the transformer to the low side of the transformer, and the "reverse charge" is powered by the low voltage side of the transformer to the high side. When the main transformer power failure operation, we must first load side, that is, first stop low side, after the power side, that is, after the high pressure side; If there are two main transformer running side by side (or other means of multiple power), when one of the main transformer power failure, if the first stop high-voltage switch, then low-voltage switch has not been disconnected, will make another master Variable power through the low-voltage switch back to the transformer power supply, resulting in transformer back-off situation; this situation not only failed to power transformer, but also increased the impact of a transformer, when there is over-voltage, etc., may cause resonance hazards Equipment safety.
- Q: I mean i want to watch transformers 3, do i have to watch 1 and 2 to enjoy the film ?
- 3 does relate to 1 and 2 No, not really but it helps to watch the prequels. I understood 2 without having to watch 1. The only thing I don't understand is why Bumblebee's vehicle mode license plate is different from his robot mode plate?
- Q: The core part of the transformer is composed of sub-and sub-components, which are generally divided into two transformers. Urgent, quick answer What is the core part of the "what" and "what" sub-composition ah? The "What" son, this "what" is to fill you ah.
- The core part of the transformer is composed of (primary coil) and (secondary coil), generally divided into two types of step-up transformer and step-down transformer. (In fact, there is not a step up and not buck the isolation transformer) Did not hear the transformer "what son".
- Q: I am making a small Tesla Coil, but have a question regarding the transformer. Would it work to simply wind one myself with the correct winding ratio to get the voltage I want (around 7-10kv) or is it better to stick with a commercially available transformer? (I would rather not have to buy one) Any advice for winding a transformer?
- I say buy one or find one that you can have for free. Whenever I build a Tesla Coil, I consider the transformer the first line of protection for pretty much any electronic circuitry on the same mains line because it acts to isolate the Tesla coil. I would never operate a home built transformer off of mains power. However, if your insistent on doing that, all I can do is advise you to get the resistance of your primary right, otherwise your transformer will quickly melt. An easier solution would be to find and contact neon sign businesses around your area. When they have to discard an old (but not necessarily bad) transformer, it COSTS them money because the EPA requires special handling because some can contain hazardous materials. Explain what your doing and if youre lucky, youll find a tech who is open to giving you a few of their junk stock.
- Q: Single-phase and three-phase transformer is what it means
- Single-phase transformer, generally refers to the primary coil is a single-phase single-coil design, the secondary can have one or more winding coil, the ideal state of the secondary total power is equal to the total primary power. For example, the common primary power supply low voltage 220 volts, the core made of mouth font, Japanese font, ring, R-shaped. Three-phase transformer, the general primary three windings, the connection is divided into triangular and star, Yanbian triangle, etc., the three winding voltage phase difference between 120 degrees, which is the common three-phase 380-volt wiring, the core The traditional three-phase three-core column, three-phase five-pin column, involute and other forms. In fact, there are many substation large-scale three-phase transformer, in order to transport and installation convenience, but also for good heat dissipation, there are three separate single-phase transformer, the use of traditional triangular or star connection input, equivalent to a Three-phase transformer.
- Q: I am throwing my sons 7th birthday party, and again this year it is Transformers. He is asking to have some unique foods as oppose to traditional party pizza. We, of course will still have a cake but I am drawing blanks to food ideas. Does anyone have any suggestions? Thanks in advance!!
- Here's a really easy nacho dip that tastes awesome! 1 package Velveeta mexican chese (you can do spicy or mild) 1 can Hormel chili +/- green onions Melt it in an oven-safe bowl in the Microwave or oven (for however long it takes to be all melted) stirring occasionally, and eat it with tortilla chips. It's awesome!!
- Q: how to calculate the secondary current of the transformer for example 1200 amps in primary ,primary voltage is 220kv and the secondary voltage is 34.5 kv of the transformer .
- For an ideal transformer, the voltage ratio is set by the turns ratio, so the transformer is a stepdown with the ratio of 220/34.5. The current ratio is also set by the turns ratio, but current goes up as voltage goes down, so the secondary voltage is 1200 x (220/34.5). Again, for an ideal transformer only.
- Q: i need a transformers costume that can transform into a car, truck, etc i need to buy it for this kid for his birthday. medium size please. and he wants it as optimus prime.he wants it to look good and if he doesn't like it, well hes gonna be sad
- wrap urself in tin-foil. lol
- Q: I broke a small transformer that I found inside of my DVD player, and I would like to have one (not for the DVD player, just separately) I would like the transformer to take in low voltage, such as a few AA or AAA batteries, and I want it to scale that up. Does anyone know where I can get one? If not are there any instructions on how to make an effective yet inexpensive one?Thanks in advance!
- A transformer cannot step up or step down DC power. (All batteries are DC). That is part of their nature. A basic transformer is nothing more than two (or more) inductor coils in close proximity, often with a steel core to help with the magnetic fields. All inductor coils are basically a coil of conducting wire, most often copper.
