Description
The GMDL-03 is a professional, high‑precision circuit breaker simulation device designed to replace real high‑voltage circuit breakers during relay protection and automatic device system transmission tests. It complies with DL/T 846.3‑2017, GB/T 1984‑2014 and IEC 62271‑100 standards, and can accurately simulate the opening/closing characteristics, coil resistance and three‑phase synchronization of 6–500kV vacuum, SF6 and oil circuit breakers.
Adopting large‑scale FPGA + power electronic drive technology, the GMDL-03 features programmable opening/closing time (10ms–1000ms) and multi‑level adjustable coil resistance (220Ω/440Ω/880Ω/1100Ω/2200Ω). It supports single‑phase/three‑phase operation and simulation of single/double trip coil breakers, with independent three‑phase control for high synchronization accuracy.

FAQ
Q: Why use a simulator instead of a real breaker?
A: Real breakers have limited mechanical life (typically 10,000–20,000 operations). The GMDL-03 has unlimited life, reduces wear on real breakers, and enables faster, safer tests without high‑voltage risks.
Q: Can it simulate different breaker types?
A: Yes. It simulates vacuum, SF6, oil‑minimum and GIS breakers from 6kV to 500kV by adjusting coil resistance and operating time.
Q: How accurate is the timing?
A: Timing error ≤±5ms; three‑phase synchronization error ≤±2ms, meeting national and international standards.
