High-Voltage Live Indicator

DXN – Q1 is a forced-lockout indicator for indoor high-voltage live display devices. It enables non-contact live monitoring through electric field coupling, combining intuitive display, forced locking, and voltage verification/phase checking functions. Compatible with indoor high-voltage equipment rated 3.6kV to 40.5kV, it serves as a critical component for preventing operational errors in power systems.

Description

Key Functionality

•  Power Indication: Three-phase (A, B, C) LED indicators correspond to the power status of each phase, illuminating when energized   and extinguishing when de-energized. The “Operation” indicator functions inversely, illuminating when de-energized to indicate safe   operation.

• Forced Lockout:  Outputs a lockout signal when energized, interlocking with electromagnetic locks to secure grounding switches, cabinet doors, etc. Unlocks only when de-energized, eliminating the possibility of misoperation.

• Self-test function:  Quickly verify the effectiveness of the indicator and interlock circuit via the self-test button to enhance operational reliability.

• Voltage and Phase Verification:  Certain models feature voltage/phase verification ports. When used with dedicated tools, they enable on-site voltage testing and phase verification.

Auxiliary Interlock: Can be integrated with electromagnetic locks, relays, and other devices to expand anti-misoperation control logic.

Application Scenarios

• Substations: Suitable for switchgear, GIS combined electrical appliances, transformers, etc., to monitor the live state of equipment and ensure the safety of switching operations and maintenance.
• Industrial Enterprises: Matched with ring main units, power distribution cabinets, high-voltage motor control cabinets, to improve the anti-misoperation performance of the factory power system and protect the safety of personnel and equipment.
• Distribution Network Facilities: Used for indoor ring main units and cable branch boxes below 35kV, to real-time feed back the live status of cables and cabinets and support the safety of distribution operation and maintenance.
• Other Indoor High-Voltage Scenarios: Such as indoor high-voltage electrical equipment in power plants, metallurgy, chemical industry and other industries, as the basic configuration for preventing misoperation, reducing the risk of electrical accidents.
