LY-DXN-T
The High-Voltage Live Display Device LY-DXN-T stands as a critical line of defense in complex electrical infrastructure. Housed in a meticulously crafted, impact-resistant polymer casing, this device provides an immediate, unmistakable visual confirmation of high-voltage presence. When you approach a switchgear panel, the crisp, high-intensity illumination of the L1, L2, and L3 indicators cuts through the ambient lighting of industrial environments, delivering instant situational awareness. The tactile feedback of the integrated self-check button offers a reassuring mechanical click, allowing operators to verify system integrity before any maintenance protocol begins.
Beyond its robust physical construction, the LY-DXN-T is engineered to eliminate the guesswork inherent in high-voltage operations. By actively monitoring terminal voltages and engaging a forced locking relay the moment voltage exceeds 40% of the nominal threshold, it physically prevents unauthorized or accidental access to energized compartments. This seamless synergy of visual warning and mechanical lockout transforms passive safety compliance into an active, fail-safe barrier. Electrical engineers and facility managers can rely on its precision-engineered internal circuitry, which operates flawlessly without the need for intrusive partial discharge testing during installation. The result is a streamlined integration process, reduced operational downtime, and a profound sense of security for every technician operating on the facility floor.
Precision engineering requires absolute transparency in technical capabilities. The following specifications detail the exacting standards and operational thresholds of the LY-DXN-T model. Every parameter, from the broad 3 to 40.5kV rated voltage range to the strict adherence to IEC61958-2000 and DL/T538 standards, reflects our commitment as a premier manufacturer to deliver uncompromising quality. Whether deployed in scientific research facilities, educational demonstration setups, or heavy-duty industrial switchgear, these specifications ensure that procurement teams and engineering specifiers have the exact data required to validate system compatibility and safety compliance.

The architectural design of the LY-DXN-T focuses on maximizing operational safety while minimizing the cognitive load on facility technicians. By integrating intuitive diagnostic controls directly into the front interface, this device empowers your maintenance teams to verify critical safety parameters instantly. The engineering behind these features ensures that every interaction is deliberate, secure, and highly responsive to the dynamic conditions of power distribution networks.
When the high voltage side is powered off and secondary working power is connected, depressing the self-check button instantly illuminates the L1, L2, and L3 indicators while disconnecting the locking relay output contacts. Releasing the button extinguishes the lights and closes the contacts, providing immediate verification of circuit health.
If the high voltage terminal voltage reaches or exceeds 40% of the nominal voltage, pressing the self-check button will keep the L1, L2, and L3 indicators illuminated and the locking relay disconnected, regardless of whether the secondary power is connected.
Designed for absolute clarity, pressing this switch when the high voltage side is de-energized ensures the phase indicators remain dark. Conversely, if the voltage is at or above the 40% threshold, the indicators must light up, offering an undeniable visual cue of energized states.
From facilitating accurate testing and analysis in industrial quality control settings to enhancing interactive classroom demonstrations with engaging visual presentations, the unit adapts seamlessly to diverse professional environments including dedicated scientific research facilities.
Procuring the right electrical safety infrastructure demands a holistic evaluation of performance, compliance, and long-term value. The LY-DXN-T is meticulously engineered across six critical dimensions to elevate your facility's operational integrity and protect your most valuable assets.
Equipped with a mandatory locking circuit output, the device physically severs the locking relay contacts the moment high-voltage terminals reach 40% of their rated capacity. This coordinates flawlessly with electromagnetic locks to create an impenetrable barrier against unauthorized access to energized bays, drastically reducing the risk of human error.
The integration of a one-touch self-check button and power test switch allows operators to validate the responsiveness of the phase indicators and locking relays in seconds. This proactive diagnostic capability significantly mitigates the risk of hidden faults, ensuring the device is always ready when it matters most.
Built to satisfy the most stringent procurement criteria, the unit fully complies with IEC61958-2000 international standards, alongside DL/T538, DL/T593, and GB/T7354 specifications. It is optimized for 50Hz, 3 to 40.5kV medium and high-voltage grids, making it a universally accepted solution for large-scale industrial projects.
Engineered to endure harsh operational climates, the internal components remain stable in extreme temperatures ranging from -30°C to +40°C and withstand daily average humidity levels up to 95%. With appropriate moisture and temperature safeguards, its deployment seamlessly extends from indoor switchgear to demanding outdoor high-voltage installations.
The architecture supports unparalleled connectivity. It interfaces smoothly with capacitive voltage dividers and sensors, while offering the unique ability to export visualization data to computers, cameras, and multimedia players. This scalability is invaluable for meticulous industrial testing, scientific data logging, and educational demonstrations.
Utilizing advanced non-contact induction technology, the device bypasses the need for disruptive partial discharge testing during installation.
