Type H (package-type) impulse voltage generator |
CDYH-K |
Modular structure |
Each level consists of 2 parallel plug-in capacitors on a steel rack composed of 4 flanges, each modular unit containing three levels is placed in a container, which is convenient for transportation, assembly and dismantling. |
It is applicable to the impulse insulation withstand test and the air gap research test of high-voltage electrical products on site or in field. |
Artistic appearance |
As shown in the figure. |
Convenient transportation |
Standard container is provided, which enables transportation, assembly and dismantling anytime and anywhere. |
Convenient waveform modulating |
Non-inductive hand-winding is employed for the waveform modulating resistor; the loop inductance is small, which makes it is easy to modulate a lightning waveform to be standard. |
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 operation |
Spring crimping connecting terminal of resistor is adopted for easy, fast and convenient replacement; An ascent ladder is provided in the generator for safe and convenient operation. |
High output efficiency |
Lightning wave efficiency≥90%; operating wave efficiency≥70% (under 3000pF total load) |
Stable system performance |
Long-time running at 80% of the rated voltage. |
Oscillating lightning wave |
Oscillating lightning wave with the efficiency ≥150% can be generated. |
Oscillating operating wave |
Oscillating operating wave with the efficiency ≥150% can be generated. |
Integrated structure is employed for the charging device and the main body of the impulse voltage generator. |
Bilateral symmetrical charging is employed for the charging device. |
Automatic grounding and automatic switching of polarity are available in the charging device. |
The discharging ball is installed in a sealed insulating cylinder and clean air is continuously supplied to the insulating cylinder by a blower. |
Dry-type capacitor is used as the main capacitor. |
Oscillating waveform modulating resistor is externally installed. |
This series of products are the initiative ones of BHT in China and have become the indispensable main equipment in GIS on-site commissioning test. |
