Product Description:

Brief Introduction
The"JDCF"series voltage transformers are inducitive type,single phase,oil filled,outdoor type.It accords to the GB 1207-1997<voltage transformer>,IEC 186 and IEC60044,This type of voltage transformer is of cascade full seal construction,The product consists of winding assembly,porcelain housing,transformer oil,base and stainless steel Bellow.

The primary winding of 110KV or 132KV voltage transformer is divided into two parts,wound separately around the upper and lower core,Wound around the lower core,three secondary windings are respectively measuring winding,protective winding and residual voltage winding.

The primary winding of 220KV or 230KV voltage transformer is divided into four parts,wound separately around two cores.Wound around the lower core,three secondary windings are respectively measuring winding.protective winding and residual voltage winding.

The active part is located to the base by suporting frame made of high quality insulation materials and is put into porcelain housing with degassed and de-watered transformer oil after vacuum treatment,All outlet wires of secondary winding and the terminal "N" of primary wnding are connected to the epoxy resin board which is in the waterproof and dust-proof terminal box of the base.There is a valve for oil-filling or oil-exhausting on the base.

Q:How does core material affect a transformer?
In 50 or 60 Hz transformers putting in a laminated magnetic iron core greatly increases the amount of magnetic flux which is generated by the primary current with the secondary on open circuit (the so called magnetising current). This enables the windings to generate a relatively high voltage with relatively small magnetising current. If you tried to make a 50/60 Hz transformer without a magnetic core (with say air or any other non-magnetic insulating material) it virtually wouldn't work because the magnetising current would be so high (the primary winding practically a short circuit). If you used a non-magnetic conducting material you'd be even worse off because eddy currrents generated in the material would prevent any flux being established and you'd have plenty of core heating but no coupling between primary and secondary. For this reason even the iron core must be laminated (unless it's non-conducting ferrite). The story is quite different for high frequencies where the inductive impedances of coils are enhanced by the frequency. There you can make quite effective air cored transformers; small ones at least - but you'd still better avoid conducting material in the core - that's what food is in a microwave oven; conducting material in the core of a high fequency transformer.
Q:1:1 60Hz transformer used at 400Hz (Sine wave)What would be the secondary voltage?
this is yet in a diverse way. enable,Epvoltage around the popular winding; Es voltage around the secondary winding;Np # of turns interior the popular winding;Ns # of turns interior the secondary winding. Then, Ep (Es(Np))/N/s; (25(20))/one hundred500/one hundred 5V Step up transformer, or T turns ratio. T Ns / Np, one hundred/20 5v, Step up transformer. to your f.y.I in case you opt to parent a step down transformer,then, use the formula Es (Ep(Ns))/Np, or TNp/Ns desire this facilitates, persist with the electrical powered industry there's an incredible destiny and a few actual sturdy money to be made in it.
Q:rheostat on DC transformer?
Transformers do not rectify and filter the output. It's AC in and AC out. A transformer either steps up the voltage or steps it down, depending upon direction. A transformer is only the first step in converting 110vac to a DC voltage. After the transformer has stepped down the 110v to 30v (AC!), it needs to be rectified into pulsating DC. Using 2 diodes (half wave rectifier), the DC will be 21v (still pulsating an unreliable for your use). If you use 4 diodes (full wave bridge), the resultant pulsating DC will be 42v. Now you need to filter it using capacitors so that it's a steady DC. You COULD use a potentiometer (rheostat) in a voltage divider network to dial down the voltage that you want to use, but fluctuations in the 110v will still be transmitted to the finished DC. So you also want to use a voltage regulator chip. That way, you get a steady, filtered, reliable DC voltage.
Q:What To People Have Against Transformers?
I don't have anything against them. They're more than meets the eye.
Q:Three-phase three-winding transformer high-pressure medium-pressure low pressure is what it means
Three-phase three-winding transformer high voltage, medium pressure, low voltage that the three sets of winding (rated) voltage level. Three windings have three windings per phase. When one winding is connected to AC power, the other two windings induce different potentials, which are used for loads of 2 different voltage levels. Power plants and substations are usually three different levels of voltage, so the three-winding transformer in the power system is widely used. Each phase of the high and low voltage winding are set on the same core column. In order to use a reasonable insulation, usually the high-voltage winding on the outermost layer, the pressure and low-voltage winding on the inner layer.
Q:How can I ground a 208v/120v control transformer ? should I just connect x2 terminal to ground?
Q:Transformer is the transmission of electrical equipment
The transformer is an electrical device that converts the AC voltage level to achieve the purpose of power transmission.
Q:What is the difference between transformers and inverters?
The transformer can change the voltage Inverter generally refers to the conversion from DC to AC.
Q:physics transformer output and input question. help?
just read your text book. lets say we have a transformer with a turns ratio of 10:1 If we apply 20 V on the high voltage side, (the side with the higher turns ratio aka 10:1), on the other side it will have 2 V. This is because of the turns ratio. Lets say that the power input on the high V side is 100W. So the current on the high V side is 100W/20V5 A Assuming ideal transformer with no losses, power in is power out. So on the other side, you will also get 100W. So the current on the low V side is 100W/250 A Basically, going from one side to the other, the V increases and the I decreases to keep the same power on both sides, as according to the turns ratio. I hope that you can figure out how the turns ratio of 10:1 made sense here. I better get best answer for this, lol. But seriously, read the text book, see how the turns are wound see how the electric field makes a magnetic field, which makes the electric field, etc.
Q:1000KVA transformer power loss is how much
The gap between the various models is also great, but also with the size of the load. To the S9 parameter is the no-load loss is 1.7KW, which is the same, full load loss is 10.3KW, this load-related. If the transformer is fully loaded, then the power loss = (1.7 + 10.3) X1H = 12 degrees 1 hour. S11 of the no-load loss is 1.15KW, full load loss is 10.3KW, full load run loss of power = 1.15 + 10.3 = 11.45 degrees 1 hour
