DXN-T-Ⅲ type - indoor high-voltage live display principle

DXN-Q (Ⅲ type) indoor high-voltage live display, DXN-T, in the DXN-Q indoor live display, DXN-Q live display, DXN-Q high-voltage live display, within DXN-Q indoor high-voltage live display (Ⅲ type) Yueqing City in the Electric Power Equipment Co., strength, credit, keep the contract, to ensure product quality, variety principles of operating characteristics and puerile, and win the trust of our customers a basic overview [DXN-Q (Ⅲ Type ) indoor high-voltage live display] is mounted directly on the indoor electrical equipment, visual display of informational safety devices with electrical equipment if the operating voltage. When the device with the operating voltage, the display window to issue flash, warning people live high-voltage equipment, there was no indication when there is no electricity. Second, [DXN-Q (Ⅲ type) indoor high-voltage live display device] use of the family unit is usually installed in the line bus, circuit breakers, transformer, switchgear, GIS combination of electrical and other places is charged to be displayed, prevent electrical misuse, the series of devices subject to the People's Republic of China power industry standard DL / T 538-2006 "high voltage electric display device" standard. Third, [DXN-Q (Ⅲ type) indoor high-voltage live display] Features Reliability: inductive (non-contact) sensors, in addition to a safe distance from the line to detect whether the line is electrified and has a clear direction, high sensitivity safe and reliable. Economy: sensor is not in direct contact with live body, without making partial discharge test installation and maintenance, easy to use, low maintenance costs and long service life. Full-featured: a flash display, self-test and start mandatory lock loop function, the real role played comprehensive mandatory locking. Adaptability: forms, can be widely used for indoor, outdoor, GIS combination of electrical and switchgear and other places. Four [DXN-Q (Ⅲ type) indoor high-voltage live display] working principle of the device is the use of electric field coupling between the sensor and the principle of high voltage electric field in a safe distance induction (non-contact) measurement. High-voltage live shows locking device consists of a sensor, a display of two parts, a total of four sensors were aligned with "A, B, C, D" three-phase electrical body and the ground, with no direct contact with high voltage live body, and maintain a safe distance, it accepts high-voltage electrical body field signal and transmitted to the judge compares the monitor; when the measured device or network live, "A, B, C" three-phase indicator light, "Operation" LED is off, and the output is forced lockout signal. When the measured device or network is not charged, "A, B, C" three-phase indicators are off, "Operation" lights, and unblocking signal, the device can operate. Device using phase control, that flash when the alarm any one phase live and outputs mandatory locking signal. When the monitor loses control power, the monitor output is forced blocking signal, to maintain the locked state. Provided on the display "self-test" function, can automatically detect various functional modules sensors and displays, in the event of any device failure, "Power" indicator light, "Operation" light does not always output forced blocking signal, to maintain the locked state. Fifth, examine the electrical / electrical inspection / nuclear phase nuclear phase ports on the monitor port provides external detection ports, with electrical inspection / nuclear phase DXN-C use.
