The power distribution specification for HTF fire smoke is the key to ensure that it can operate stable and reliable in emergency situations.The following is a detailed description of the HTF fire smoke power distribution specifications:
Power supply requirements:
· HTF Fire Fighting Tobacco Fan should accept a stable and reliable power supply to ensure that it can run normally during the fire.It is recommended to choose a three -phase AC power supply with a rated voltage of 380V and a rated frequency of 50Hz.
· In order to ensure the stability and reliability of the power supply, the voltage stabilizer and overvoltage protection device should be installed.These devices can effectively resist the fluctuations and abnormal conditions of the grid, and ensure the continuous operation of the fan.
Power supply load requirements:
· According to the principle of electricity load grading of fire equipment, the power supply load level of HTF fire smoke exhaust fan in civil buildings shall meet the corresponding regulations.For a type of high -rise civilian building, its fire smoke exhaust fan should be a first -class load; for the second category of high -level civilian buildings, its fire fire exhaust fan should be a second -level load.
· In order to meet the requirements of the first and secondary power supply loads, a dedicated dual -circuit power supply line should be adopted to ensure the continuous power supply of the fan.At the same time, the automatic switching device of the end power supply should be set to ensure that the other road can be automatically put into operation when the power supply fails.
Power distribution line installation requirements:
· The distribution line of the tobacco exhaust fan should be installed strictly in accordance with the specifications to ensure the safety and reliability of the line.The line should be protected and avoids contact with combustion.
· Pipe selection of the power distribution line should meet the fire performance requirements.It is generally recommended to use metal tube and paint fireproof coatings outside the metal tube to improve the fire resistance of the line.
Power distribution box and control circuit requirements:
· The power distribution box of the fire fire fan should be set in a position that is easy to operate and maintain, and there should be obvious logos and warning signs.
· The design of the control loop should be concise and clear, and the variable frequency speed regulator shall be used as the control device to avoid adverse effects on the operation of the fan.
Other precautions:
· In the power distribution design, the power and current of the fan should be fully considered to ensure that the selected cables, switches and other electrical components can withstand the operating load of the fan.
· Check and maintain the power distribution system for regular tobacco exhaust fan, discover and handle potential safety hazards in time to ensure the normal operation of the system.
In short, the power distribution specifications of HTF fire fire exhaust fan are an important guarantee to ensure that it can stabilize and reliable operations in emergency situations such as fires.In practical applications, design and installation should be carried out strictly in accordance with the specifications, and daily maintenance and inspection should be strengthened to ensure the full performance of its performance.
