Features oil-immersed transformers

a, oil-immersed transformer low-voltage windings except for small-capacity copper wire, generally used copper foil around the pumping cylinder structure; high voltage winding cylindrical multi-layer structure, so that the winding ampere-turns of the distribution of the balance, magnetic flux leakage small, high mechanical strength, resistance to short-circuit capacity.
b, core and windings each adopted tightening measures, the fastening portion is tall, with a low-voltage wiring, etc. are self-locking lock nut, using a no hanging heart structure can withstand transportation Britain earthquake.
c, the coil and the core by vacuum drying, transformer oil vacuum oil filter and oil filling process, the moisture inside the transformer to a minimum.
d, the tank using a corrugated sheet having respiratory function to compensate for temperature changes caused by changes in oil volume, so that the product does not conservator, apparently reducing the height of the transformer.
e, due to replace the conservator the corrugated sheets, transformer oil and the outside world, thus effectively preventing oxygen, moisture into the insulation and cause performance degradation.
f, according to the performance of the above five points, to ensure that the oil-immersed transformer oil change is not required in the normal operation, greatly reducing the maintenance cost of the transformer, while extending the life of the 11kv dry type transformer.

Necessary point uses oil-immersed transformers

As technology advances, more and more inseparable from the electrical current life, so a lot of related equipment and electricity, today to say something about some of the knowledge of the transformer:
Oil-immersed transformers and other products different is that oil-immersed transformer which is equipped with transformer oil, after reaching the ignition point of spontaneous combustion and fire may occur, resulting in accidental injury, the use of oil-filled transformers need to note the following:
First, oil-immersed transformers shall be related to the current specification, provided a fixed water spraying fire extinguishing system. Oil-immersed transformer plant should be set up in a separate room, the door of the room should be B fire doors open outwards, and direct access to the outdoors or corridors, not open to other rooms. Second, power and distribution transformer manufacturer and other oil-filled electrical equipment during a single fuel than 1000Kg, set oil storage and a common set sump pit and pebbles to spare to put a transformer fire and unloading.
Third, when the spacing between adjacent fire between the two oil-immersed transformer does not meet the requirements should be set at the top of the fire wall or fire wall add fire water curtain. You can only set fire wall or fire water curtain between the single-phase oil-immersed transformers.
Fourth, the amount of oil in more than 2500kg of oil-immersed transformers and oil between the 600kg-2500kg of oil-filled electrical equipment, the fire spacing should be less than 5m.
Fifth, when the oil-immersed transformer factory facades from the outer edge of less than 5m, the total thickness of the transformer plus 3m below the horizon and scope within 3m of the outer edge of each plus sides, should open doors and windows and holes; it outside its scope Doors and fixed windows firewall, its fire resistance of not less than 0.9h.

Effect of transformer short-circuit the force

We have studied physics knowledge, in a magnetic field in a current-carrying conductor will have to bear the mechanical force, so when the transformer windings through the current time, but because of the role of current and the leakage magnetic field in the winding will generate an electromagnetic mechanical force its size depends on the magnetic field flux leakage current density of the wire multiplied, and we all know, have direction from left to decide. When the single phase pole mounted transformers is running under normal load, then the role of the force in the wire is relatively small, but in the event of sudden short-circuit, because the maximum short circuit current for the rated current 25-30 or will be greater, however, It is calculated according to the electromagnetic force generated between the windings and short circuit current and proportional to the square, so the mechanical force short circuit during normal operation will be substantially greater than the force of more than a few hundred times, and the speed of the force generated when a short circuit is very fast, in such a short period of time is too late to cut off the short-circuit circuit.
In short, the huge short-circuit electromagnetic force, may make the transformer windings will be damaged so there are many parts manufacturers in the design of the 500kva power transformer, you must study and other short-circuit power transformer in tolerance and winding in the case of a short circuit mechanical strength for verification, in order to ensure the normal operation and use of the transformer, we must take into account the stress problem transformer.

What is the oil-immersed transformers

Oil-immersed transformer insulating oil is used as a ground terminal of the housing to its insulation, it is a liquid dielectric transformers. This is the core of the 100kva single phase pole mounted transformer  windings which are immersed in transformer oil, the oil can not be the case in the absence of work (test may be), the oil can flow away the core, the winding of the heat, and the oil is insulated.

One is the effect of edge insulation oil, the other is the heat. Oil-immersed transformer inside the body frame, the core windings are immersed in insulating oil. So called "oil-immersed" in. Transformer oil usually paraffinic oil production oil # 10, # 25 intermediate base oil produced oil, naphthenic oil production # 25 and # 45 transformer oil. With the development of modern science and technology, power system insulation material used has changed. Network now runs transformer insulation forms: SF6 11kv single phase transformer, epoxy organic insulation (dry) transformer. However, the voltage level is limited to 110kV.

Tank role oil transformers

The body of (winding and core) 100kva oil transformer are housed in a tank filled with transformer oil, steel plate welded into the tank. In small transformer tank by tank shells and cover composition, the body of the transformer housing on the box, the lid can be lifted out of the body of open repair.

Pole-mounted transformers

Polemounted transformers often include accessories such as surge arresters or protective fuse links. A self-protected transformer includes an internal fuse and surge arrester; other transformers have these components mounted separately outside the tank.  Pole-mounted transformers may have lugs allowing direct mounting to a pole, or may be mounted on crossarms bolted to the pole. Aerial transformers, larger than around 75 kVA, may be mounted on a platform supported by one or more poles. A 3 phase step up transformer service may use three identical transformers, one per phase.

The difference between dry type transformers and oil transformers

The difference between dry type transformers and oil transformers
Dry type transformer and transformer oil compared to, in addition to the same working principle, the biggest difference is that there is no oil inside the transformer, while there are many differences.
1. Cooling: oil immersed transformer is oil as the main means of insulating transformers, rely on oil as a cooling medium (self-cooled air-cooled water-cooled.). Booster station master general variants are oil-immersed, variations than 20KV / 500KV.Dry-type transformers rely on air convection cooling. Small-capacity transformer ratio 6000V / 400V.
2. The overall structure: from the appearance point of view, different packages, dry-type transformers can directly see the core and coil, and transformer oil transformer can only see the shell; dry-type transformers are mostly silicon rubber casing, while oil Most transformers
3, the capacity and the voltage is different: dry-type transformers are generally applicable to power distribution capacity 1600KVA mostly in less voltage 10KV or less, there are individual achieve 35KV voltage level; and oil-type transformers but they can do it all from small to large capacity voltage level also do all voltages; 1000KV UHV test line under construction in China, the use of certain oil-type transformers.
4, insulation and heat are not the same: dry-type transformers are generally used resin insulated by natural air-cooled, high-capacity cooling by fan, while oil-insulated transformers by insulating oil, insulating oil by circulating inside the transformer coil tropical produce to the transformer radiator (piece) on cooling.
5, the load bearing capacity different: Usually dry-type transformers should be operated at the rated capacity and the oil transformer overload better.

Small single-phase transformers Introduction

Transformer is passed through the electromagnetic coupling between electric power equipment, use can be summarized as follows: supplying electric power economy, a reasonable allocation of power, safe to use electricity. In fact, while it is changing the current transformer, the resistance may change
Reactance and number of phases. Single phase transformer which has a small capacity, light weight, simple wiring, easy to install, etc., referring to the small transformer capacity 1000V.A of transformers (for example, 11kv single phase transformer). The easiest small single phase transformer core consists of a closed (constituting a magnetic circuit) and wound around the core of two different turns, insulated from each other windings (circuit configuration) composition. Such applications Transformer in life is very extensive.

With Gilled Radiator Transformer

It is well known in the station design, the main transformer step-up transformer general should be chosen, that is, its elevated voltage side voltage than the rated voltage, high voltage level of 10%, its purpose is to enable the sending end voltage hydroelectric line voltage after loss after the loss of equilibrium with the system terminal voltage large hydropower station, but 10kva step up transformer has no formal step-up transformer, this transformer is used especially in rural small hydropower transmission distance is long, the line voltage loss often causing the outlet voltage is too high and the problem of arrears reactive power generator, which is unreasonable, it is recommended that you buy 3 phase step up transformer.
