Phase detector

OneLYWHX-9900Phase detectorIntroduction

is aFully intelligent wireless high and low voltage voice phase analyzerBreaking through the voltage level limitations of traditional nuclear phase meters, nuclear phase can be detected in extremely low voltage lines, achieving10VAutomatic phase detection at voltages of up to 550kV (such as 400V, 10kV, 35kV, 66kV, 110kV, 220kV) eliminates the need to purchase multiple phase detectors or configure high and low voltage detectors separately based on voltage levels, saving costs, reducing portability, and saving time and speed. For high-voltage line phase detection (voltage exceeding 400V), the metal probe hook of the detector can be gradually brought closer to the wire. When an electric field signal is induced, phase detection can be completed without direct contact with the high-voltage wire, which is safe!When the voltage exceeds 35kV, non-contact core phase must be used.This nuclear phase analyzer also has functions such as testing phase, frequency, phase sequence, electrical verification, and transformer group determination.

fromdetector、receiver(host）TheTelescopic insulating rod、monitoring software、USB communication cableThe wireless transmission of test data can penetrate through wall obstacles, with a straight-line transmission distance of about 100 meters. Host selection: 4.3 inches65K色LCD color screen, which can display phase, frequency, phase sequence, and nuclear phase results on the same screen,Dynamic Vector Graph IndicationClear and intuitive; Having voice prompts such as "X signal normal, Y signal normal, in-phase, out of phase" will make testing simple and easy; The host is also designed with a USB interface, and the data saved during on-site testing can be imported into the computer through monitoring software for easy access and management of historical data. The insulating rod is made of alkali free glass fiber cloth as the base material, and is heated, rolled, baked, and cured with epoxy phenolic resin as the adhesive. It has the characteristics of high insulation, stretchability, moisture resistance, impact resistance, bending resistance, and lightweight.

Due to the fact that some users may not use this instrument frequently, and may only use it once every six months, if they do not forget to charge the battery for a long time, it may cause the battery to not work properly. Users may also find it inconvenient to purchase rechargeable batteries of the same specifications. Therefore,LYWHX-9900Two battery power supply methods have been designed. When the rechargeable battery is damaged, it can be replaced with a regular battery (the host uses 6 1.5V LR6 batteries); The detector uses two pieces of 6F22 9V.

Also known as“Nuclear phase analyzer, nuclear phase analyzer, wireless high-voltage nuclear phase analyzer, wireless high and low voltage voice nuclear phase analyzerHigh voltage digital voice phase detector, wireless high-voltage intelligent phase detector”Wait a minute.

This instrument can store 200 sets of data. If the storage is full, it will display the "full" or "FULL" symbol, and the memory must be cleared before it can be stored again.

4. Data retrieval

In test mode, hold downREADEnter the data search mode with the key“READ”Symbol indication. Simultaneously display the 001st set of stored data automatically, and then pressarrowClick to flip through. This instrument is equipped with "+1, -1,+10, -10" quick access to stored data function. Pressup and down arrowsPress the key to query by increasing or decreasing the step size by 1Left and right arrowsUse the key to increase or decrease the step size by 10 to query.

5. Data deletion

In test mode, pressCLEARPress the key to enter the data deletion dialog box, and then press againLeft and right arrowsSelect 'Yes' or' No 'with the key, then press againCLEARConfirm whether to delete and return to test mode with the key. Data cannot be restored after deletion.

6. Data upload

Connect the USB communication cable between the computer and the host, turn on the computer, run the monitoring software, and you can read the stored historical data, upload it to the computer, and manage the data.

7. Superior filtering

In order to improve the accuracy of the test, the instrument has added an upper level filtering function, which means that during the kernel phase, the filter is pressedFILTERThe key can activate or deactivate the filtering function, and the LCD dynamically displays when activated“FILTER……”This way, the results of the nuclear phase will be more accurate, but the testing time will be extended.

8. Self verification

Please perform self calibration before on-site phase verification to confirm that the instrument is functioning properly. Connect the two clips of the self calibration line to the hooks of the two detectors, and then plug the self calibration line plug into a 220V power socket. Perform self calibration on the same live wire. If there is no power, the neutral wire may have been plugged in. Simply plug the self calibration line plug back in.

9. Nuclear phase, electrical verification, frequency, and phase sequence testing

Connect the insulation rod, install the antenna, turn on the device. If the communication between the host and the detector is normal, the red status light will be on; Communication is abnormal, the white status light is on. At the same time, the host will voice prompt "X signal normal" and "Y signal normal".

When nucleating, first bring the X detector close to or in contact with any phase line, and then bring the Y detector close to or in contact with other phase lines to be nucleated. High voltage nuclear phase, the detector does not need to directly contact the high-voltage wire. The detector hook is gradually brought closer to the wire. When an electric field is sensed, the detector will emit a "beep beep beep beep" prompt sound to complete the electrical verification function. Low voltage core phase (400V and below), especially for low-voltage core phase of distribution boxes, please replace the metal probe hook with a metal probe and use the probe to directly contact the low-voltage wire. When the voltage is too low, it is necessary to contact the bare wire for testing.

The nuclear phase is based on the X detector and displays the fixed A phase. If the phase angle of the two detectors is between -20 ° and 20 ° (340 ° and 360 ° are -20 ° and 0 °), the detection result of the Y detector is A, which is classified as in-phase; If the phase angle between two detectors is between 100 ° and 140 ° or 220 ° and 260 °, it is classified as out of phase. At the same time, the host voice prompts "same phase" or "out of phase".

When the phase angle is between 100 ° and 140 °, the detection result of the Y detector is B, which is in sequential order; The phase angle is between 220 ° and 260 °, and the detection result of the Y detector is C, which is the reverse phase sequence.

10. Battery charging or replacement

When the battery voltage is insufficient, the low voltage symbol is displayed. Please charge the battery in a timely manner. If the battery is still low after multiple charges, please replace it with a brand new battery. If users are unable to purchase rechargeable batteries of the same specifications, they can purchase regular batteries instead (the host uses 6 1.5V, LR6 batteries; One 6F22 9V detector is used.

When replacing the battery, make sure the instrument panel is turned off.

Detector battery replacement: Loosen the four screws on the bottom cover of the detector, carefully open the bottom cover, and replace it with a brand new qualified battery. If you continue to use lithium batteries of the same specifications, you need to weld the corresponding wires. The detector is reserved with a 6F22 battery interface. If replacing the 6F22 battery, the original built-in lithium battery needs to be removed and replaced with a 6F22 battery.

Host battery replacement: Loosen one screw on the host battery cover, open the host battery cover, and replace it with a brand new and qualified battery. Pay attention to the polarity of the battery specifications, cover the bottom cover or battery cover, and tighten the screws. The host can use 1.5V and LR6 batteries.

After replacing the battery, pressPOWERPress the key to confirm if the battery replacement was successful. Battery replacement must strictly follow the same performance and parameters as battery replacement.
