Ultrasonic Local Inspection Instrument

The SG-2000 is a detection device to diagnose the hidden trouble of power line faults by collecting abnormal ultrasonic signals of power line and analyzing them by software. The device can judge the location and type of hidden trouble under the condition of no power failure. The device collects the ultrasonic abnormal signal through the ultrasonic detector (ultrasonic sensor) and transmits it to the host. At the same time, the type and severity of hidden trouble are accurately diagnosed through the built-in analysis software of the host, and converted into audible sound signal and waveform output, so as to help the patrol inspectors accurately find the hidden trouble of line faults and prevent the occurrence of malignant faults, It avoids unnecessary power failure, improves the reliability of power supply, improves the work efficiency of patrol inspectors and reduces the labor intensity of patrol inspectors.

• Portable design, small, light, easy to carry, one person can operate.
• Hand-held non-contact, visual, audible and display waveform, charged non-contact detection.
• It can scan the open (outdoor) equipment of the transformer station on line to find and locate various partial discharges: corona, arc, flashover, creepage, disconnection, arcing, etc
• Find and locate insulator discharge on the tower, climbing of open cable head, and local discharge detection and positioning of underground cables.
• Leakage detection of a high-pressure sealed gas liquid.
• In the handover and preventive test of the power system, in the local discharge test of the main transformer and GIS, the device can be used with the local discharge. Therefore, if there is local discharge, it can distinguish between internal or external discharge, if external discharge, specific discharge points can be located.
• In the factory test of large oil immersed transformer, dry-type transformer, GIS and other manufacturers, the device is used with the partial discharge instrument in the partial discharge test. If there is discharge, it can not be seen whether it is internal discharge or external discharge on the screen of the partial discharge instrument. Use the handheld patrol locator to scan the test object. The external discharge point can be quickly found and located. If there is no external discharge, it is judged as internal discharge.
• The 5-megapixel HD camera can easily focus to detect fault points and take photos of the rod and tower identification and faulty equipment.
• The embedded GPS receiver automatically stores coordinate data and provides GPS navigation function to facilitate query and save detection paths.
• With the function of detecting temperature and humidity, it can detect real-time environmental temperature and humidity.
• Have data saving function, can realize data playback function.
• The display is a color touch screen for easy detection and use.
• Moderate intensity of the green laser light aiming, the human eye is easy to track in the sun.
• High sensitivity, direction and directivity, can be accurate positioning of line faults.
• Strong focus capability and can be tested on a vehicle with a driving speed of 30 km/h.
• Ultrasonic detection can be applied for a noise environment, free of ambient sound.
• The detection adopts non-contact method, and the effective detection distance can reach 50 meters, which is safe and reliable.
• Data management and evaluation are convenient using background software.
