The TZY-DXN indoor high-voltage live display device is a device installed in indoor AC 50Hz, rated voltage 3.6kV-40.5.6kV high-voltage switchgear or high-voltage electrical equipment, used in conjunction with high-voltage live sensors. It displays through high brightness light-emitting diodes to reflect whether the electrical equipment has operating voltage and has a forced electrical interlocking function. This device complies with DL/T538-93 "Technical Conditions for High Voltage Live Display Devices".

The monitor uses high brightness light-emitting diodes. When the high-voltage equipment is running at voltage, it will emit light to remind the staff that the equipment is live.

1. Long service life. Overcoming the problem of short display life caused by neon lights in the past, the average time between failures is over 700000 hours.

2. Reliable operation. The forced type adopts a highly reliable switching power supply, which not only solves the problem of voltage fluctuations that are easily affected by simple power supplies that use capacitors or power resistors for voltage reduction, but also solves the problem of high heat generation and reduced service life of displays using this simple power supply when the high-voltage system is not charged.

The forced working power supply has strong adaptability and is compatible with both AC and DC. The input voltage range can reach AC/DC100V-200V. The mandatory type adopts high reliability digital detection technology, which improves the sensitivity of detection (effective locking can be achieved by 50% or less of the rated voltage value) and prevents misoperation of relay output.
