LYZGS DC high voltage generator
The first:brief
introduction
DC
high voltage generator are researched and manufactured in light of China
industry standard ZBF 24003-90 《Universal technology
Conditions about portable DC Hipot Tester》.They
are applicable to the electric power branch, power department of factories ,
scientific research units, railway, chemical industry, power plants,which use
them to do test on zinc oxide arrester ,magnetic blowing arrester, power
cables, generators, transformers, switches and other equipments.
DC
high voltage generator are used IF
voltage circuit and the latest PWM technology to do closed-loop adjustment and used voltage
feedback to improve voltage stability.The use of high power IGBT devices with
excellent Performance and their drive technology,and the measures about special
shielding, grounding and isolation in accordance with electromagnetic
compatibility theory，all of this makes the DC
high voltage generator high-quality,
portable and can withstand the rated voltage discharge and prevent being
damaged.
The
major advanced technology components of LYZGS
series DC high voltage generator equipment are made from the United States,
Germany, Japan and other countries so that the equipments become more reliable
and more stable.
The second: product’s
characteristic
1.It’s the smallest and lightest in the same types of products and
looks more beautiful and reliable.Simple operation
and complete function is easy for wild work.
2.
DC high voltage generator are used the latest PWM technology, high power IGBT devices and voltage feedback
to make the voltage stability higher,and
the ripple coefficient smaller.
3.
The major advanced technology components of LYZGS
series DC high voltage generator equipment are made from the United
States, Germany, Japan and other countries so that the equipments become more
reliable and more stable and can stay continuous discharge directly to earth.
4.The
voltage meter and current meter all have high precision and exact measure and
use figure display. The resolution of voltage meter is 0.1KV and current meter
is 0.1uA,The figure voltage meter displays is just the voltage on tested res
and it needn’t additional Inductive Potentiometer(ipot).The high voltage end is
used rotund shield figure meter so it can stay the shoot of discharge and has
good performance of anti-jamming.
5.
It has high stabilization of voltage regulation and regulates voltage
Smoothly.The output voltage regulator uses a single multi-turn inductive
potentiometer.
6.
It has many functions such as cathode output, operating from zero, continuously
adjustable, over-voltage protection, over-current protection, back to zero
protection, grounding protection, special disconnection protection.All
technical indexs are better than industry standards.
7.
The added high-precision 75% VDC-1mA functions makes it esay to do Zinc oxide
Arrester tests.You just need to push it gently and the value will be displayed.
There is a 75% VDC-1mA function button on the control box to do Zinc oxide
arrester test. Push the 0.75 UDC - 1mA button when the current rises to 1000
uA. The value Data voltage meter and current meter shows is data of 75% .Then
return the voltage ipot to zero immediately, and push the green button to cut
off high-voltage power switch.
8.
The over voltage set fuction uses number dial switch which can display the
figures of voltage clear and makes it esay to operate it.The unit it displays
on the dial is KV.
9. American technology and special design is used to
voltage multiplier.This makes it easy to do tests.
10-1.Three
hided supporting feet makes the voltage multiplier more stable(Apply to 600KV).
10-2.
The up cover of control box can be used as hurricane lamp base and cover the Voltage Multiplier to make it more stable.
