Description |
Type H impulse current generator |
|
Model |
CDLH |
|
Structure |
Type H |
Each level consists of 2 parallel plug-in capacitors on a steel rack composed of 4 flanges, various levels are spliced level by level which is convenient for dismounting and repair and the integral structure is stable. |
Application |
Applicable to the residual voltage test and the shunt characteristic test of an entire arrester of 35 - 110kV or 220kV or higher voltage level. |
|
Advantages |
Artistic appearance |
As shown in the figure. |
Strong function |
The shunt characteristic test of an entire 220kV arrester can be conducted for 16 lines at maximum. |
|
Convenient waveform modulating |
Hand winding is employed for the waveform modulating inductor with flexible arrangement, so it is easy to modulate various waveforms. |
|
Fine synchronization performance |
A unique synchronization technology is adopted with a synchronization range no less than 20% and an out-of-control ratio no more than 1%. |
|
Simple and convenient operation |
Spring crimping of the resistance connecting end is adopted, through which, the replacement is easy, fast and convenient; |
|
High output efficiency |
Lightning wave efficiency≥90%; operating wave efficiency≥70% (under 3000pF total load). |
|
Convenient and stable moving |
It is easy and stable to move equipment since air-cushion transportation system which has been successfully used on 6000kV equipment is equipped. |
|
Stable system performance |
Long-time running at 80% of the rated voltage. |
|
Performance |
Lightning wave |
Standard lightning wave no more than 2,400kV can be generated. |
Operating wave |
Operating wave no more than 1,800kV can be generated. |
|
Current wave |
8/20μS lightning impulse current wave can be generated; |
|
