The digital high-voltage wireless nuclear phase meter adopts the latest power electronic detection technology and wireless transmission technology. The operation is safe and reliable, and it is easy to use. It overcomes many shortcomings of the wired phase detector and meets the national quality supervision and inspection of power safety tools. Test relevant standards.
The digital high-voltage wireless nuclear phase meter is used for phase checking 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. Received by the nuclear phase meter and phase comparison, the qualitative results after the nuclear phase. Because this product is wireless transmission, it is truly safe, reliable, fast and accurate, and adapts to various nuclear phase applications.
Shanghai digital high voltage wireless nuclear phaser features:
The main advantage is that the lead wires connecting the two grids (power supplies) are removed (distance up to 20m) and can pass through walls and partitions (boards) without any restrictions on terrain and facility architecture, which improves safety.
The operation is extremely convenient and only one person is required to operate one person.
When the digital high-voltage wireless nuclear phase meter works, the digital signal is sent to the receiving end through the wireless sending module, thereby reducing the interference, reducing the error, and greatly improving the performance of the instrument.
In use, the receiving device is first operated on the measured grid electrical conductor, and then the receiving device is operated on another grid electrical conductor under test. If the phases of the two grids being tested are the same, the language repeatedly indicates: "the same phase", If the phases of the two grids being tested are different, the language repeats the prompt: "Attention, different phase."
Insulating operation tubes (materials) are selected from ordnance enterprise's three-ball brand moisture-proof insulation tube, which conforms to EC/1C78 standard and has the characteristics of moisture resistance, high pressure resistance, impact resistance, and bending resistance.
The principle structure of Shanghai Digital High Voltage Wireless Nuclear Phase Analyzer:
The high-voltage phase detector consists of two transmitters and receivers that are electrically disconnected from each other. Both devices are equipped with electrodes. The electrodes can be connected to (or in contact with) the conductors to be tested, and a red emitter has its electrodes. The shape of the hook is for hooking onto the wire, and the other is yellow for the receiver. The shape of the electrode is a dome shape for easy access to the wire. These electrodes are used as antennas for transmitting and receiving signals, transmitters and receivers. The end should be connected with the matching insulation operating rod.
After the transmitting device works normally, the acquired phase-linked grid voltage signal is processed and modulated, and then transmitted to the receiving device. The receiving device demodulates the received grid voltage signal with phase characteristics and collects the received voltage signal from the receiving device itself. The real-time comparison of the phase-correlated grid voltage signals can measure the phase difference. The high-voltage phase detector considers the phase difference to be less than 10° in phase with the phase of the power line, and the phase difference greater than 30° is out of phase.
