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:Differences between electronic transformers and electronic ballasts
Electronic ballasts can be simply modified into electronic transformers, the output of high-frequency voltage can also be converted through the Xiaoji Diode rectifier DC. There is no voltage regulator circuit, the output voltage will change with the power of the load, so this circuit is called the electronic transformer instead of switching power supply.
Q:Characteristics of Electronic Rectifier and Ordinary Rectifier
The ballast is composed of electronic components, light weight, high efficiency, more energy than the inductive energy, with the lamp The racks are easy to install together.
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?
Rectifier: Turn AC (or pulse) into DC. Out of the DC more stable the better.
Q:Electronic ballasts and inductive ballasts have several output lines?
Fluorescent tube electronic ballast output is four lines, the wiring diagram attached to the ballast shell, the corresponding two groups were connected to each end of the tube.
Q:Solid state relays are different from rectifiers
The rectifier is a device fabricated using a semiconductor element. Rectifier as the name suggests is the use of semiconductor characteristics in the AC circuit can be alternating current into a DC current device
Q:What is the difference between rectifiers and regulators?
he rectifier is a rectifier, which simply converts AC (AC) into a DC (DC) device. It has two main functions: first, the alternating current (AC) into DC (DC), the filter after the load supply, or supply the inverter; second, to the battery to provide charging voltage
Q:What is the difference between the regulator and the rectifier?
The regulator is used in voltage regulation. Rectifier is the exchange of electricity into a DC different equipment.
Q:What is the difference between a rectifier and a DC / DC converter?
Rectifier is the converter current properties, DC-DC converter is adjusted to change the DC voltage
Q:What is the difference between a five-wire rectifier and a four-wire rectifier?
Four lines of no feedback line, five lines of feedback line.The engine does not have to consume fuel in order to overcome the magnetic moment.
