1. Comply with the power supply management system, strictly follow the electrician's operating procedures; implement special-time electrician special management for the low-voltage power distribution room to ensure normal power supply.
2. Check the operation of the equipment every day and fill in the operation record truthfully. The device was found to be abnormally repaired in time to ensure that the device is operating normally.
3. Regularly maintain the equipment, keep the power distribution room clean and tidy, prevent dust pollution and small animals from entering the short circuit accident. Except for the necessary supporting tools, the power distribution room shall not store flammable, explosive and other items.
4. The equipment must be powered off during maintenance, and ensure that there is an obvious disconnection point on the circuit that needs power failure maintenance equipment. In addition, the warning sign “Some people are forbidden to close” is suspended at the disconnection point.
5. When special circumstances must be carried out, there should be reliable protective measures, and work in accordance with the safe operating procedures. Special personnel are on site to prevent electric shock.
6, stop (send) electricity operating procedures:
(1) Power failure procedure: Disconnect the shunt load switch and the knife on the low-voltage side - disconnect the low-side main air switch - disconnect the low-pressure side main knife switch.
(2) Power transmission procedure: contrary to the power failure sequence. Close the low-pressure side main knife switch - close the low-pressure side total air switch - close the splitter switch and load switch.
7. Mains-generation conversion operation procedures:
(1) Mains-generation power supply system with automatic input function.
After the mains power failure for a few seconds, the generator starts and establishes the voltage, the electric interlock device acts, and the line is automatically transferred to the power generation. At this time, the electrician manually converts the central air conditioner, the split air conditioner, and other parts of the line that need to be manually converted.
After the utility power is restored, the above equipment and lines are re-converted and restarted. The conversion operation should be carried out by referring to "Stop Power Operation Sequence".
(2) No automatic input function Mains-generation power supply system.
When the utility power fails, the generator is manually started. After the voltage is stabilized, the conversion is performed step by step. After the utility power is restored, the switching operation is performed in the reverse order. The conversion operation should be carried out by referring to "Stop Power Operation Sequence".
