I.Products Introduction
HZ-8600 Phasing Unit,
for MV overhead distribution circuit,used for detection of
high-voltage power grid closing point on both sides of the phase sequence is the same.
Two power line connection before must check phase sequence, or line may be short
circuit. The instrument suitable for36KV power transmission line, and can test whether line
charged. The Instrument adopts the wireless transmission technology, safe and reliable
operation, easy to use.
II.Working Principle
The instrument consists of two transmitters (x and y) and a receiver. Two emitters can be
judged whether line charged, and launch phase signal. Receiving meter receives two
emitters’ signal, to judge whether the same on both sides phase sequence.
III.Security Matters
1. Insulating rod before using should be voltage withstand test.
2. The standard configuration insulating rod length is 3 m, corresponding voltage for ≤
220 KV. If the measurement circuit voltage higher than 220KV, please use the length of
more than 3 meters of the insulating rod.
3. Operation hand position not more than insulating rod handle position.
IV.Technical Characteristic
1. Accuracy:When phase sequence is same: the error≤ 5 °.
2. The frequency accuracy
：
±0.1HZ.
3. Measuring voltage range is 36KV .
4. The transmitter and the receiving host transmission distance is more than 130 meters,
the maximum distance between the two transmitters is about 260 meters.
5. Results (in phase, interphase) using A standard, phase difference acuity ≥30 ° for out
phase, the phase difference < 30 ° are in phase.
6. Screen shows two lines at the same time of phase difference, frequency, waveform
and the vector diagram.
7. The host shows battery, half an hour without automatic shutdown operation.
