The power distribution cabinet of the hospital ventilation system is an electrical equipment specially designed to
provide power support and protection for the hospital ventilation system, including power supply lines,
control protection devices, distribution circuits, etc., to ensure the stable operation of the ventilation system.
Power supply stability: The hospital ventilation system is a key facility to ensure the safety and hygiene of
the medical environment, and the power distribution cabinet provides stable power supply for the system.
Safety and protection: The control and protection devices inside the power distribution cabinet can
effectively prevent electrical accidents and ensure the safe and reliable operation of the ventilation system.
Convenience and maintainability: A reasonably designed power distribution cabinet facilitates daily inspection,
maintenance and updating, which is conducive to the operation and management of energy supply systems and
equipment by hospital logistics management personnel.
Partitioning and customization: According to the functional differences and operating times of various
departments in the hospital, the power distribution system should be reasonably partitioned after detailed
investigation and research to meet the parameters required by each department, reduce the adverse effects
between different areas, and facilitate management and maintenance.
Air purification and pressure control: Some special departments of the hospital, such as the operating
department and sterile room, have strict requirements on air quality. The ventilation system needs to be effectively
controlled by the distribution cabinet to meet the specified air purification standards while maintaining the necessary
positive or negative pressure requirements.
Emergency backup power supply: The distribution cabinet of the hospital ventilation system usually needs to be
connected to the emergency diesel generator set to ensure that it can quickly switch to the backup power supply when
the main power fails to ensure the continuous operation of the ventilation system.
Load classification and power supply scheme: According to the contact between medical electrical equipment and
the human body and the consequences of power outages, medical sites are divided into different categories. Among them,
equipment involving patient life safety and lighting electricity are particularly important loads in the first-level load and
need to be covered by emergency power supply.
Low-voltage distribution system: The low-voltage distribution system adopts a distribution method combining radial
and trunk types, and some parts adopt a linking method to improve power supply reliability and facilitate management.
Line laying and protection: The line laying of the distribution cabinet of the ventilation system needs to consider the
protection requirements to avoid the influence of high-energy rays and radionuclides and other diagnostic and treatment
equipment, and ensure that the cable trench cannot be directly connected to prevent radiation leakage.
