Kev Tiv Thaiv tsib-tiv thaiv kev siv cov qauv:
1. Circuit breaker interlocking: In the closed state, the mechanical interlocking hole automatically inserts a Φ8mm interlocking rod to prevent accidental opening. The brightness of the opening position indicator light is >300Cd / m²
2. Hauv kev sib tw sib xyaw: Siv SMC txoj haujlwm sensor, kev tiv thaiv tsis kam<0.1Ω. During maintenance, it is necessary to verify that the locking electromagnet suction is >150N
3. Valve synchronization: thaum trolley tau muab tshem tawm, lub valve kaw lub sijhawm txawv yog<0.5s, and the contact box protective cover withstand voltage value must pass the 42kV/1min test
4. Temperature warning: The cable room uses a PT100 sensor and sets a two-level alarm: 70 degree warning and 90 degree tripping. Cov ntaub ntawv Refresh hloov dua tshiab dua lossis sib npaug rau 5s
