Product Description:

Siliconrectifier of GKA series for switching closing


Siliconrectifier of GKA series for switching closing is designed according to GB2859standard, mainly used for high-voltage switching closing power supply in powerplants, substations, power stations and industrial and mining enterprises,which is controlled   electromagnetically, DC power supply forprotection. The product adopts screen-type structure three-phase bridgerectifier circuit with capacitor energy storage, insulation monitoring, lackphase, over voltage, over current, power supply automatic cut off and other protectiondevices. Product allows the impact of 10 times under rated output DC current(short-term value) , the duration not less than 1S and not more than 3S, theimpact of time interval is 2S. Product is generally multiple type, also can bemade in single type upon customer’s request.

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:How does the rectifier turn AC into DC?
It is loaded with a very small harmonic interference and a power factor on the grid. Diode Rectifier The simplest of all rectifier classes is a diode rectifier. In the simplest form, the diode rectifier does not provide any means of controlling the output current and voltage values. In order to apply to industrial processes, the output value must be controlled within a certain range.
Q:Is the rectifier pulse the better?
The rectifier is a rectifier, which simply converts AC (AC) into a DC (DC) device. It has two main functions: first, the AC (AC) into DC (DC), the filter after the supply of the load, or supply the inverter; second, to the battery to provide charging voltage. Therefore, it also plays the role of a charger.
Q:Solid state relays are different from rectifiers
Relays and rectifiers can not replace each other, usually ordinary relay is composed of coils, iron core, contacts and other components, many types of relays, such as voltage relays, current relay pressure relays, thermal relays, speed relays, gas relays, weak magnetic relays, liquid Bit relay, phase sequence relays, etc. according to different needs as a circuit control and protection.
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:Motorcycle rectifier performance is good or bad
Judge the rectifier is the most simple and the way is that with the increase in speed, the voltage does not change to normal, that is, whether you are driving, or the gap, as long as the speed up, the voltage is not high and high
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:What is the difference between the regulator and the rectifier?
Thyristor regulator, also known as "thyristor power regulator" "SCR power regulator" or "power regulator". "Thyristor", also known as "SCR" (SCR) is a four-layer three-terminal semiconductor device, put it in the middle of the power supply and load, coupled with the corresponding trigger control circuit board, you can adjust the voltage applied to the load , Current and power.
Q:What is the difference between a five-wire rectifier and a four-wire rectifier?
Five lines of function are as follows: black line for the feedback line, responsible for the lock after the power supply voltage collector back to the regulator. To analyze and compare, and then determine the best time to short-circuit regulator, and will not be too high voltage and charge the battery. Other line color function and the same as the four lines so, four more advanced, the price will be high. And will save some fuel
Q:Electronic ballasts and electromagnetic ballasts are different
Electronic ballasts can also have more features, such as by increasing the current frequency or current waveform (such as square wave) to improve or eliminate the flashing phenomenon of the fluorescent lamp; can also be through the power inverter process so that the fluorescent lamp can use DC power. Some of the shortcomings of traditional inductive rectifiers make it being replaced by increasingly sophisticated electronic ballasts
