What is a trigger transformer?
The
Trigger Transformer is a low -floor shooting transformer that initiates pilot currents that produce the main initial currents for cold cathode devices filled with gas. It is usually produced by the number of turnover in the secondary winding is several times higher than in the primary winding, although it is also possible that the primary winding is part of a much larger secondary winding. This large curve allows the triggering transformer to provide the trigger voltage that is not otherwise available from the main power supply. This magnetic field produces a time -variable current in the secondary winding. The trigger transformers are able to generate high -voltage rupture that can ionize most of the gases used in cold cathode devices. Or resonance, which maintains enough trigger energy. This is very similar to the mechanical pendulum, where originally pushed to one side of the rest, the pendulum will move regularly from one extreme position to the other as long as all kineticEnergy scatters. The energy stored in the capacity is like a potential energy on one extreme position of the bob, while the energy stored in the magnetic field inside the magnetic core of the trigger transformer is like kinetic energy, because it passes through its resting position.
The electrical ballast that limits the electrical current in the circuit is similar to the trigger transformer. For example, in electric lighting, cold cathode tubes are not directly connected to the main voltage supply. The electric ballast is connected in a series with a tube, so the current is limited to very safe levels.
High-ending HVSLT itself is used for neon tubes in the notice boards. In addition to HVSLT, in addition to the step transformer, it limits the current as a ballast. HVSLT does not require another trigger transformer because the high voltage generated by HVSLT is sufficient to start the PR currentOudem load even during a cold start.
Popular use for a trigger transformer is a flash for photo effects and lighting. The flash pipe, such as a neon bulb, is set to standby when the main terminals are under a voltage of about 100 volts. This level is not enough to ionize gas in a tube to cause a flash. The third terminal, called the trigger terminal, is closer to the common main terminal on the tube. To trigger a flash, the output from the conventional transformer ionizes the gas between the trigger of the pipe and the common terminal, which leads to the launched flash.
