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
