Product Description:

Traction silicon rectifier of GQA,GQF,KGQF  series

Traction silicon rectifier of GQA GQF KGQFKGQA series are mainly used for ground electric locomotive traction and DCpower supply of electric locomotive traction in mine for mining enterprises.

The product adopts three phase full controlbridge, three phase half control bridge and diode rectifier, smoothingreactor added on full control and half control bridge to improve DC currentwave form, and restrict short current and keep current continuity. Three phasebridge input terminal uses vacuum AC contactor, load is E  and 100% IH, 150% IH for 2 hours, 300% IH for1mintue, has flow cut-off protection function, can be operated under the shaft.

We provide rectifier transformer with threedifferent types: dry, epoxy cast resin and oil immersed.

Q:How does the rectifier turn AC into DC?
This control can be accomplished by applying a so-called on-load tap changer for the machine. As a typical case, the on-load tap changer controls the input AC voltage at the primary side of the rectifier transformer, thus enabling the output of the DC value to be controlled within a certain range. Typically, the on-load tap changer is used in conjunction with a saturable reactor connected in series in the rectifier output circuit.
Q:Is the rectifier pulse the better?
The more the rectifier pulse the better. Rectifier: Turn AC (or pulse) into DC. Out of the DC more stable the better.
Q:Differences between electronic transformers and electronic ballasts
Electronic transformer and electronic ballast in front of the self-oscillation circuit is basically the same, but behind the output of the circuit is different from the electronic ballast self-oscillation after the high-frequency voltage connected to an inductor, used to store light fluorescent, Transformer shock after the high-frequency voltage connected to a high-frequency transformer, used to 300V or so high-frequency voltage into 12V or so high-frequency AC, and then used to light 12v halogen bulb.
Q:What is the difference between a car voltage regulator and a rectifier?
Its role is to convert AC into direct current, known as rectifier. The specific wiring is the rectifier has generally been connected inside the generator, the regulator is a power supply is a, a ground wire, F then the generator excitation winding. Regulator models more specific circumstances specific treatment
Q:What is the difference between rectifiers and regulators?
Regulator: a power supply circuit or power supply device that can automatically adjust the output voltage. Its function is to stabilize the power supply voltage required by the large or unbalanced electrical equipment and stabilize it within the set value range.
Q:What is the difference between the regulator and the rectifier?
Rectifier (English: rectifier) is the exchange of alternating current into direct current devices, can be used for power supply devices and detect radio signals. The rectifier can be made of a vacuum tube, a pilot tube, a solid-state silicon diode, a mercury arc, or the like.
Q:Can the rectifier change the voltage?
The correct call is "fluorescent lamp ballast", not the rectifier. The role of the ballast is: 1, fluorescent lamp start, the starter contact in the moment off, the ballast inductor electromotive force and power supply voltage superposition, the lamp mercury gas breakdown, to stimulate the fluorescent light. 2, the fluorescent light is lit, the ballast to play the role of impedance, limiting the current through the light.
Q:Ups the role of the filter and rectifier
Ups in the rectifier at the front of the filter is the exchange of clutter, there is no rectification effect. Rectifier from the role of DC conversion, so some rectifier rectifier after the waveform is not stable but a change in the value of the voltage and the structure of the rectifier, you can use the oscilloscope to observe the changes in the wave head, so the To pure DC after rectification in the filter
Q:The difference between rectifiers and transformers
Fluorescent lamp ballast is because it starts with high current and high voltage, to be activated, only a lower voltage and a smaller current to maintain its working condition, it must be ballast. Other transformers are due to their rated voltage range, to be adjusted
Q:Full-wave regulator rectifier and half-wave regulator rectifier! Where is the difference?
The full-wave rectification before and after the waveform and half-wave rectifier is different from the full-wave rectifier in the use of two half-wave, which improves the efficiency of the rectifier, and the entire current is easy to smooth. Therefore, in the rectifier widely used full-wave rectifier, half-wave rectifier is only used in less demanding circuits.
