I. Product Introduction

1.Summary

HZ-8600E Central cabinet wireless phase meter (hereinafter referred to as the "Instrument") is used for phase calibration of switchgear with five protection cabinet functions. By binding the collector to the busbar of the upper and lower knife switches of the central cabinet, six identical measurements can be achieved. At the same time, the instrument is also equipped with a universal transmitter for connecting two high-voltage lines to the grid or ring network. The instrument is suitable for 5V~220kV AC transmission lines and secondary live display phase detection, and also has the function of line live detection.

The instrument adopts digital wireless transmission technology, which is safe and reliable to operate, easy to use, and overcomes many disadvantages of wired phase detectors. The appearance of the instrument is shown in the following figure:

II. Working Principle

The instrument consists of 2 pairs of transmitters, 3 pairs of collectors, and 1 receiving host. The transmitter can determine whether the line is live and measure the phase and frequency of the line. When in close range nuclear phase, the transmitter sends measurement data to the receiving host via radio, and the receiving host calculates the phase difference between the two lines based on the data measured by the transmitter to determine whether they are in the same or different phase.

2、Safety precautions

1. During on-site testing, operations should be carried out in accordance with the safety distance standards for high-voltage testing set by the power department.

2. The standard configuration is a 3-meter insulated pole, corresponding to a voltage level of ≤ 220kV. If the measured line voltage is higher than 220kV, please use insulated poles with a length greater than 3 meters.

3. When operating the nuclear phase, do not hold it beyond the position of the insulating rod handle.

Be careful:

1) Handheld devices and transmitters use 3.7V rechargeable lithium batteries, please do not replace other batteries.

2) The handheld device and transmitter should be charged using a matching DC5V1A power adapter. Do not use other specifications of power adapters.
