Product features

1. Fixed time overvoltage protection, with independent adjustable action voltage and delay, directly connected to the secondary side of the system voltage transformer to achieve overvoltage alarm and tripping.
2. The front panel 6-digit DIP dip switch binary weighted setting action voltage does not require a potentiometer, and the set value is intuitive and easy to check, avoiding accidental adjustment.
3. Static electronic circuit design, compared to old-fashioned electromagnetic relays, has good consistency of action, high accuracy, low power consumption, and no wear of mechanical moving parts.
4. Dual pair conversion outlet contact, capacity 5A, can simultaneously drive trip circuit, signal circuit and alarm indication, without the need for intermediate relay expansion.
5. Plug in modular structure, the module can be removed from the base for maintenance, and the base wiring does not move. When replacing spare parts, there is no need to rewire, which shortens the power outage time.
6. Equipped with a mechanical trip indicator (or LED), which can be manually reset after the action, making it easy for operators to judge the fault and record the action on site.
7. Equipped with MMLG type test terminal block, it can short-circuit CT and isolate PT circuits during operation, facilitating relay calibration without power outage.
8. Wide range DC auxiliary power supply, suitable for 110V DC operation power supply system in substations, reliable operation under power fluctuations.
9. Industrial grade seismic and electromagnetic interference resistant design, suitable for long-term operation in strong electromagnetic environments inside high-voltage switchgear.

Usage scenarios

Used for overvoltage protection in medium and high voltage power systems. Typical scenarios: 10kV/35kV substation bus PT circuit, generator transformer group overvoltage protection, parallel capacitor group overvoltage protection, long-distance transmission line overvoltage monitoring. When the system experiences power frequency overvoltage or ferromagnetic resonance overvoltage, an alarm or circuit breaker will be triggered after a set delay to protect the insulation of the primary equipment; Mostly used for retrofitting old electromagnetic/static voltage relays and replacing faulty spare parts in old substations.
