GENERATOR OF HIGH VOLTAGE
(Principle of the transforming)
This simple experimental loop generates a high voltage that arrives up to 80 V and at 250 V, from you pillage common, and so a lamp of fluorescent neon can be ignited and up to one lámàra burned. tra of a dmostración of the principle of operation of the transforming. It is possible to be used for a presentation in Feria de Ciencias.
AS IT WORKS
It works of the following way: a vibrator (VB) constructed with laminae of brass and eletroimán transforms the DC of the batteries into pulsating DC to excite the coil of low tension of the transformer.
It is obtained, by induction, uaa higher tension in the other coil of the transformer, which can produce small sparks.
The current that is obtained is low, since energy cannot be created. Of this form, when we increased the tension in a circuit, its current falls in the same proportion.
Down the form can be seen to arm this experiment:
The most difficult part of equipment is the electromagnet and the construction of the vibrator can be seen in the yellow oval (VB) that is the most important part. This vibrator is constructed in a wood base, has two laminae of brass or band (steel lamina) and an electromagnet enrrollado on a great screw. Eletroimán has approximately 500 turns (returned) of copper wire enameled (Number 32 AWG or similar) enrrolladas on a great screw of about 2.5 cm. Is the typical electrical circuit of tibre for c.c. It is necessary to notice the positions of laminae so that the vibration can happen that quickly exchanges the current of the circuit.
The capacitor C1, improves the performance of the vibrator and can have values between 10 mF to 47 mF. The transformer can be of 110 V or 220 V and one 12 exit from 3 to 500 V and from 50 to mA. A common neon lamp can be used.
For the batteries portapilas is used. he is better to use great batteries than it has more current.
VB - Vibrator
Feeding - 6 V - 4 batteries.
C1 - 10 mF to 47 mF - capacitor eletrolítico of 16 V.
Transformer with primary of 110 V or 220 12 secondary V and from 3 to V with 50 to 500 mA of current.
Lamp common neon (NE-1, NE-2).
Others: Wire, weld, portapilas, enameled wire, wood base, etc.
