HRZJ3
Microcomputer-Typed Detector of Anti-distributed Capacitive
Type Direct current Grounding |
|
| |
With
continuous improvement of 20 years, it keeps the advanced
technology and creates the domestic origination.
Technological characteristics:
It is a new generation invented on the basis of HRZJ1
and HRZJ2 type.
1. It is possible to find out one-point or multi-point
abort situation without installation, electrical cutting,
and insulated pumping.
2. It directly displays grounding resistance data, which
is convenient to master insulating condition. Range: 0-99KΩ
3. It directly displays grounding electrical capacity
data, which is convenient to master electrical capacity
disturbing condition. Range: 0-99uKor 0-99KΩ.
4. Directly displaying the grounding direction can lead
the instructors to search rapidly.
5. It can adjust to the AC& DC looping current grounding,
token-ring power supply grounding, and diode isolation
power supply grounding.
6. Referring to semiconductor light grounding, it is easier
to find out complicated signal loop.
7. Pliers with “heart-shape” designing, it shares the
big or small lines without changing pliers.
8. 24V、48V、110V、220V direct current system shares a suit
of direct current grounding detector.
9. Detecting sensitivity: ≥50KΩ, both index and numerical
display is available, which is easy to judge. Special
requirement can reach ≥100KΩ
10. Accuracy：100%
11. Anti-electrical capacity disturbance：>1200KΩ/uF
12. Signal output power: <0.15w, containing protection
of current limitation, which has no influence on relay
protection of power system, and automatic or operative
loop, using safely.
13. Signal frequency stability: ±0.02Hz
14. Dimension of signal generator：280mm（width）×100mm(height)×300mm（depth）
15. dimension of portable machine：126mm（width）×70mm（height）×156mm（depth）
16. Deluxe Copper-aluminum Outer package is easy to carry.
17. AC & DC power supply: AC/DC 220V |
