Fire emergency power supply installation guide
In the fire emergency system, the installation of fire emergency power supply is very important. Its main function is to ensure the normal operation of fire fighting equipment and systems in the event of a fire or other emergency. The following is a detailed guide to fire emergency power installation.
Installation environment requirements:
The battery of the fire emergency power supply should be installed in a well-ventilated place. If installed in a sealed environment, there should be a ventilation device.
Acid batteries shall not be installed in places with alkaline media, and alkaline batteries shall not be installed in places with acidic media.
Fire emergency power supply should not be installed near pipelines, warehouses, operating rooms and other places with flammable gas.
If the rated power for single-phase power supply is greater than 30kW and the rated power for three-phase power supply is greater than 120kW, install an independent fire emergency power supply.
Power Settings:
The power supply distance of distribution line, cross section of wire, voltage drop loss and other factors should be considered comprehensively, and the centralized power supply should be set according to the division of fire protection zones. The total power of the lamp is greater than 5kW system, should be dispersed centralized power supply.
Centralized power supply should be set in the fire control room, low-voltage distribution room, distribution room or electrical shaft; There should be no combustible gas pipes, inflammables, corrosive gases or vapors in the installation site.
Acid batteries should not be set up with alkaline medium materials; Alkaline battery Settings should not store substances with acidic media.
The installation site should be well ventilated, and the ambient temperature of the installation site should not exceed the nominal operating temperature range of the battery.
Power supply requirements:
In the centralized control system, the centralized power supply should be powered by the special emergency circuit of the fire power supply, and the decentralized centralized power supply should be powered by the fire power distribution box in the fire protection zone, the floor of the same fire protection zone, the tunnel section, the subway platform and the station hall.
Installation steps:
The selection of wires, cables and protective tubes should meet the design requirements, and fire-resistant wires and cables should be laid for evacuation lighting.
The installation of emergency lighting distribution boxes should be clearly marked with other general lighting distribution boxes.
When the EPS power cabinet is installed in the electrical shaft, there should be a heat dissipation channel around the power cabinet.
The neutral line N at the EPS output should be directly connected to the grounding device of the building.
Operation and maintenance:
The installation of emergency lighting controller, central power supply and emergency lighting distribution box should be firm and not tilt; When installing light walls in wall-hanging mode, take reinforcement measures.
The device should be firmly grounded and clearly marked.
When installing batteries (groups) of emergency lighting controllers or centralized power supplies onsite, check the specifications, models, and capacities of the batteries (groups) and ensure that they comply with the design documents.
CONCLUSION
The above guide combines multiple information to ensure the standardization and safety of fire emergency power installation. In actual operation, relevant codes and standards should be strictly followed to ensure the correct installation and use of fire emergency power supplies.
