Wireless high-voltage nuclear phase meter method of use:
When the live conductor is touched, the acoustic signal can be heard and 4 indicators are on. After 5-10 seconds, LED2-4 will be off and the sound signal will be stopped. The transmitter will set the working time as 5-10 seconds after voltage measurement. Enter the phase measurement, at this time only one LED indicator light, if the sound and light signals after 5-10 seconds, that is, the battery power is insufficient to replace the battery. If you want to test the other phase of the line, you need to remove the transmitter from the line until the LED1 goes out and put the transmitter on the line to do another voltage measurement. Ibid.
When entering the measurement mode, the transmitter transmits radio frequency signals to the air while a part of the signal is transmitted along the line as an antenna. Once the receiver can recognize the signal, the receiver immediately starts operation.
Wireless high-voltage nuclear phase meter maintenance:
1. This instrument is a precision instrument and should not be opened at will.
2. If you do not use it for a long time, you should remove the collector battery.
3. Change the battery at least once a year.
4. The instrument should be stored in an environment that avoids humidity, high temperature, and dust.
5, insulation rod should be used before the first pressure test.
6. Insulation rods are subjected to a pressure test once a year.
Note: The upper end of the first section of the insulated rod has a built-in antenna of 350mm long, and it is not possible to perform a withstand voltage test. The built-in antenna and the insulation voltage of the outer wall of the rod are 15kV.
Attachment : Safety Code:
1. During on-site testing, the operator should operate according to the high-voltage test safety distance standard of the power department.
2. The tested insulating rod voltage level is ≤220KV.
3, (Special attention: Please carefully check the insulation performance of the insulation rod before each use, pay attention to the weather, strictly abide by the relevant provisions of the national high-pressure test!)
4. The safety rules and regulations of the unit should be carefully implemented during use, and the relevant regulations of the DL408-91 safe work procedure (electrical part of the substation of the power plant) should be strictly observed. Carefully store the instrument and check the insulation regularly.
5. The insulation rod is 6-section retractable. When it is in use, regardless of whether the working voltage is the highest voltage, the telescopic insulation rod should be pulled to the longest state (about 3.1 meters), and the handshake can only be held in the sixth quarter. Do not shake hands in the fifth quarter.
6. Avoid using radio transmitters (interphones, etc.) simultaneously during use to avoid interference with the receiver.
Talking about the Use and Maintenance of Wireless High Voltage Digital Nuclear Phase Analyzer
The wireless high-voltage digital nuclear phase meter is used for phase verification and phase sequence verification of power lines and substations, and has functions such as nuclear phase, phase sequence detection, and electrical inspection. With strong anti-interference, meet (EMC) standard requirements, adapt to various electromagnetic field interference occasions. The high-voltage phase signal to be measured is taken out by the collector and directly emitted after being processed. It is received by the nuclear phase meter and phase comparison is performed to locate the result after the nuclear phase.
