HRVLF-30/1.1
HRVLF-50/5 HRVLF-80/1.1 0.1Hz超低頻高壓發生器 |
|
| |
新一代交流耐壓試驗儀器，替代諧振耐壓裝置，用于發電機（電機）、電纜、絕緣子、電力電容器、大型變壓器等大容性設備的交流耐壓試驗�，F場、戶內試驗使用的首選。也可作超低頻信號源使用。
△使用0.1Hz超低頻的必要性
1、 理論上容量是工頻的1/500，真正體積小、重量輕、操作簡便。
2、 超低頻交流測試不會在絕緣中產生樹狀間隙。
3、
不會像直流試驗那樣易損壞電纜。不受試品之電容效應影響。
4、
有害極化電荷不會在測試過程中進入電介質。
△功能特點
1、 采用數字變頻技術，微電腦控制，測試過程完全自動化。
2、 大屏幕液晶顯示，漢字操作，顯示試驗波形（正弦波），打印試驗報告。
3、 過流過壓自動保護，自主知識產權依據電力標準研發和設計制造。
4、 多頻率選擇：0.1Hz，0.05Hz，0.02Hz，增強了帶載能力。 |

HRVLF Series of Portable 0.1HZ
Digital Very-low-Frequency High Voltage Tester |
|
| |
The new generation
of AC withstand tester, replacing harmonic withstand tester,
is widely used in AC withstand test of large capacity equipments
such as generator, cable, insulator, power capacitor, large
transformer etc. Not only can it be the first choice of
on-site and outdoor testing, but also as the ultra-low frequency
source.
Advantage of 0.1Hz HRVLF series
1、Small volume, light weight, easily to operate. Theoretically
speaking, the capacity is of 1/500 of power Frequency.
2. AC ultra-low frequency tester doesn’t form tree-clearance
in the insulating condition.
3. Unlike DC test, it’s uneasy to destroy cables; meanwhile
the capacitance effect of testing articles has no influence
to it.
4. Pernicious polarization charge would make no way to
dielectric during the testing.
Features of function
1. Adopting digital convention technology and microcomputers
controlling system make the testing process completely
automatic.
2. The large screen of liquid crystal and Chinese input
operating system insure that testing wave-form (Sinusoid
Wave) can be displayed; testing reports can be printed.
3. Auto-protection of over-current and over-voltage, the
research，design and manufacture of independent intellectual
property rights according to power standard
4. Multi-frequency selections (0.1Hz，0.05Hz，0.02Hz) strengthen
the load-bearing capability. |
