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. Human voice prompt, male voice "in phase", female voice "phase-out".

7. Screen shows two lines at the same time of phase difference, frequency, waveform and the vector diagram.

8. The host shows battery, half an hour without automatic shutdown operation.

9. Two emitter and receiver use rechargeable lithium battery.

10. Have high pressure test report and the function of the phase sequence.

11. High pressure when measuring the leakage current < 10 uA.

12. Transmitter power consumption < 0.1 W, receiving host work power consumption < 0.3 W.

13. Host lithium battery capacity is about 2200 mAH, transmitter battery capacity is about 350 mAH.

14.Working environment: temperature  - 35 ℃ ----- + 45 ℃ ; humidity  ≤ 95% RH.

15.Storage conditions: temperature - 40 ℃ ------ + 55 ℃ ; humidity  ≤95% RH.

16.The weight：about 5 KG.

17.Instrument package size: 71 cm long * wide 26 cmm * 11 cm high.
