LY-1A Voltage Relay Product Introduction (English)
The LY-1A Voltage Relay is a versatile control component specifically designed for power system monitoring and protection, capable of real-time voltage parameter detection and logic control in both AC/DC circuits. Featuring modular design principles, the relay delivers rapid response to abnormal voltage conditions including overvoltage, undervoltage, and power loss scenarios, providing effective protection for electrical equipment while enabling automated system control functions.
Integrating precision electromagnetic induction mechanisms with low-power electronic circuitry, this relay offers wide adjustment range and high sensitivity. The operating voltage can be continuously adjusted within 30%-130% of rated value to meet customized application requirements. With built-in multi-layer anti-interference design, the product effectively suppresses harmonic interference and transient pulses, ensuring measurement stability in complex electromagnetic environments. The contact system employs silver alloy material combined with double-break structure design, extending electrical lifespan to over 100,000 mechanical operations under normal load conditions.
Applicable to 0.4kV-35kV distribution systems, the LY-1A relay is widely used in voltage protection circuits for power plants, substations, rail transit systems, and industrial automation facilities. Typical applications include on-load tap changer control, reactive power compensation device switching management, and critical load voltage monitoring. Multiple installation options are available, supporting both panel-mounted and DIN rail-mounted configurations compatible with standard control cabinet systems. The flame-retardant engineering plastic housing meets industrial safety protection standards.
Key product advantages include: 1) Optimized operating time design ensures response within 20ms across full range for rapid protection; 2) Transparent observation window with mechanical position indicator enables intuitive status monitoring for maintenance personnel; 3) Wide-temperature design maintains stable operation from -25℃ to +55℃, adaptable to diverse climatic conditions. Manufactured under strict quality control, each unit undergoes comprehensive operational characteristic testing and aging experiments prior to delivery, guaranteeing long-term operational reliability.
