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:The difference between the rectifier and the inverter
Low-voltage direct current conversion boost into high-frequency high-voltage alternating current rectifier filter into high-voltage direct current and then converted to low-frequency mains. Because the low voltage to be converted to high voltage will use the transformer, the transformer volume want small, then use high frequency to convert.
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: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: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:Ups the role of the filter and rectifier
In the UPS input to install passive filter and active filter is mainly to prevent *, inhibit the input current harmonic components. Commonly used passive filter is generally composed of R, L, C frequency selection of the selected network, it can selectively attenuate the input signal does not need the frequency components, effectively play a filtering role, the grid also play a filter effect
Q:How does the rectifier turn AC into DC?
Rectifier principle In the two basic types of rectifiers based on high-power diodes or thyristors, the high-voltage AC power of the grid is converted to DC power through the transformer. Other types of rectifiers that refer to the future (near or far away): chopper, chopper DC / DC converters or current source inverter active rectifiers based on unprotected diode frontier products.
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.
Q:Can the rectifier change the voltage?
Close the switch, the 220 voltage by the ballast, the lamp at both ends of the filament added to the starter, this time the lamp is not bright, the lamp is only played a role in the power supply to the starter. 220V added to the starter, the neon inside the ionization occurred (this time the red light), ionization of the neon temperature, high temperature so that the starter's movable contact to the static contact deformation, so that the two contacts Phase connected.
Q:Can the generator install the rectifier?
You said the car in the battery to charge its own (12V) is a rectifier. But can not put the 12-volt alternator, the power of the "rectifier" to 48 volts, rectifier: only the generator AC, through the rectifier into a DC charge into the battery, and can not be boosted to 48 volts, say the load is too large On the generator is influential, and its power is limited, can not be changed.
Q:Why is the battery connected to a rectifier
Access network site is rarely equipped with air conditioning, so the ambient temperature changes, the internal chemical reaction speed of the battery has a great impact. Rectifier temperature compensation function is to minimize the impact of temperature on the battery. The general requirements of the ambient temperature for each rise once, each section 2V battery float voltage to reduce 3 ~ 5mv, and vice versa. As a result of a variety of batteries using different materials and materials, the actual application of the battery manufacturers to give the data to adjust.
