GCPD-2000 Ultrasonic Partial Discharge Inspection Instrument Introduction: The ultrasonic partial discharge inspection instrument is a detection device that collects abnormal ultrasonic signals from power lines and analyzes them through software to diagnose hidden dangers in power line faults. This device can determine the location and fault type of hidden faults without power outage. After the device collects ultrasonic abnormal signals through an ultrasonic detector (ultrasonic sensor), it transmits them to the host. At the same time, it accurately diagnoses the type and severity of hidden faults through the host's built-in analysis software, and converts them into audible sound signals and waveform output to help with inspections. Personnel can accurately discover hidden dangers of line faults, prevent the occurrence of malignant faults, avoid unnecessary power outages, improve power supply reliability, and at the same time improve the work efficiency of inspection personnel and reduce the labor intensity of inspection personnel. Features: 1. Portable design, small size, light weight, easy to carry, and can be operated by one person. 2. Handheld non-contact, visual, audible and waveform display, live non-contact detection. 3. It can conduct live scanning of open (open-air) equipment in transformer stations to discover and locate various partial discharges: corona, arc, flashover, creepage, disconnection, arcing, etc. 4. Discover and locate insulator discharge on towers, creepage on open-air cable heads, and detect and locate partial discharge on underground cables; 5. In the handover and preventive tests of the power system, and in the partial discharge tests of the main transformer and GIS, this device is used in conjunction with the partial discharge instrument. If there is partial discharge, it can be distinguished whether it is internal discharge or external discharge. If it is external discharge, Specific discharge points can be located. 6. In the factory tests of large oil-immersed transformers, dry-type transformers, GIS and other manufacturers, the device is used with the PD meter in the partial discharge test. If there is a discharge, it cannot be seen on the screen of the PD meter that it is internal Whether it is discharge or external discharge, use a handheld inspection locator to scan the sample. External discharge points can be quickly discovered and located. If there is no external discharge, it will be judged as internal discharge. 7. Leak detection of high-pressure sealed gas and liquid. 8 The 3-megapixel high-definition camera can easily focus on detecting fault points and take photos of tower signs and faulty equipment. 9. The embedded GPS receiver automatically stores coordinate data and provides GPS navigation functions to facilitate querying and saving detection routes. 10. It has the function of detecting temperature and humidity, and can detect the ambient temperature and humidity in real time. Technical Parameters: Circuit system: Analog circuit and digital circuit for anti-interference filtering CPU: Main frequency 533MHz Memory: Running memory 256MB DDR2, 1GB NandFlash Display: OLED LCD display with backlight Interface: SD memory card, USB, serial port, headset SD memory card: TF card above 8G Camera: 3 million pixel HD camera Accessory configuration: GPS, temperature and humidity, high-brightness laser pointer Storage functions: GPS coordinates, time/date, temperature/humidity Measurement range: -7dBμV ~ 68dBμV Frequency range: 20-150kHz Resolution: 1dB Error: ±1dB Sensor sensitivity: -65dB (0dB = 1volt/μbar rms SPL) Sensor center frequency: 40kHz Operating environment: -25℃ ~ 70℃ Sensor diameter: 16mm Relative humidity: 0 - 95% Charger specifications: Input: 100-240V, 50/60Hz Output: voltage 20V, current 3.25A Power supply: Battery powered: lithium battery Working hours: more than 10 hours Battery protection: The LCD backlight turns off when there is no operation within 5 minutes, and automatically shuts down when there is no operation within 20 minutes. When the battery power is lower than 5%, the system beeps to prompt you to save data in time, and the user needs to shut down and charge.
