the electrical safety specifications for screw air compressors, with the core of ensuring safety from four aspects: design, operation, maintenance, and emergency response. The key points are as follows:

2025,12,20

1. Preliminary Design: The power supply system must match the cable specification (e.g., 75kW models with ≥35mm² copper core cables), equipped with independent circuit breakers and residual current protectors (operating current ≤30mA); the machine room should be away from humid and dusty areas, with a maintenance channel of ≥0.8m reserved and lighting ≥200lux.

2. Operation: Adhere to the "Three Checks and Two Prohibitions" – check circuits, verify parameters, and test protection functions before startup; monitor data during operation (shut down immediately if abnormal); prohibit uncertified operation, maintenance during operation, and other irregularities.

3. Maintenance: Tighten terminals, clean contacts, and inspect cables monthly; test insulation resistance (≥0.5MΩ) and grounding resistance (≤4Ω) annually, and replace vulnerable parts used for over 5 years; implement the "lockout-tagout" system during maintenance.

4. Emergency Response: For electric shock, cut off the main power first before rescuing; use dry powder or carbon dioxide fire extinguishers for electrical fires (prohibit water); analyze the cause after the accident, revise specifications, and conduct safety education.
