As a professional Medium Voltage Components manufacturer in China, Comewill factory's High Voltage Live Display Device is used to indicate the live status of high-voltage circuits and provide safety interlocking functions. It helps prevent electrical misoperation and accidental entry into energized areas.
The device is typically used together with high-voltage live sensors and is suitable for indoor switchgear with rated voltages ranging from 3.6 kV to 40.5 kV at 50 Hz or 60 Hz. Certain models, such as the GSWD series, can also be applied to outdoor 35–220 kV power systems.
The product uses long-life LED indicators and a dust-proof and moisture-resistant enclosure. Its technical performance complies with IEC 61958 standards and supports functions such as electrical testing and phase checking.
1. High-brightness LEDs with long service life for clear visual indication
2. Ultrasonic plastic welding technology used in the enclosure for enhanced dust-proof and moisture-proof protection
3. Low starting voltage, typically ≤ 25% of rated voltage
4. Relay control capability up to AC220V / 5A
5. IP-rated protection for reliable operation in industrial environments
6. Wide operating temperature range from −25°C to +70°C
The operating principle of a high voltage live display device is mainly based on electric field induction or voltage transformer technology.
The device detects the electric field strength surrounding high-voltage equipment and converts it into an electrical signal. This signal drives indicator lights or a display module to show the live status of the equipment. The advantages include, simple structure, lower cost, easy installation.
This method converts high voltage into a low-voltage signal through a voltage transformer, which is then processed by the control circuit to display the energized status.
Comewill factory's high performance High voltage live display devices are widely used in power systems and industrial environments. Typical applications include power system equipment, high-voltage switchgear, transformers, circuit breakers
