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: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:The basic requirements of the rectifier
Increased input power The rectifier / charger should have an initial power requirement of 20% of the rated load and gradually increase the input power to 100% of the rated capacity over a 10 second time interval. In redundant UPS systems, the input power of each rectifier / charger should be delayed by 5 to 300 seconds to reduce the impact on the generator
Q:Where can the rectifier be used?
Rectifier generally exchange into DC, so the place to use DC generally have rectifiers, such as DC motor in front of the inverter inside, and some places are DC transmission, substation which also has a rectifier, low voltage weak electrical control circuit board generally used To 5v DC, the front of the circuit board also has a rectifier. Hope to adopt.
Q:Electronic ballasts and inductive ballasts have several output lines?
Electronic ballast according to the different lamp and the number of output lines are also different, usually 6 lines, 2 connected to the power supply, the other four for each of the two groups of light on both ends of the lamp. But if it is a ring lamp, there are 2 lights and 4 foot of the foot, 2 lights of the lamp with the electronic ballast only four output lines.
Q:Full-wave regulator rectifier and half-wave regulator rectifier! Where is the difference?
Half-wave rectifier circuit is a rectifier components (such as diodes) one-way conduction characteristics to rectify the common circuit, remove the half-week, the remaining half of the rectification method, called half-wave rectifier.
Q:How does the rectifier turn AC into DC?
By controlling the voltage drop across the reactor, the output value can be controlled over a relatively narrow range. Thyristor rectifiers are designed to be very close to the diode rectifier of the thyristor rectifier. Because the thyristor rectifier electrical parameters are controllable, so do not need to carry pumping ...
Q:The difference between rectifiers and transformers
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. In contrast, a set of devices that convert DC into alternating current is called an "inverter".
Q:What is the difference between a rectifier and a DC / DC converter?
DC / DC converters are complex. If it is high DC into a low DC, then it is relatively simple, (low power) with a regulator or resistance can be achieved, such as 7815 and so on. When the voltage difference is large, you can use SCR and so on.
Q:Differences between electronic transformers and electronic ballasts
Electronic transformers usually refer to the switching power supply, in some cases it can replace the traditional power transformer to do power, so called electronic transformers.
Q:Why is the battery connected to a rectifier
The rectifier should have an automatic float management program. When the AC power is restored and the power supply is resumed or the continuous float is running for about 3 months, the battery pack is automatically charged to reduce the charging time, eliminate the battery behind the battery and prevent the passivation of the battery active material.
