Valve regulated sealed lead-acid batteries (VRLA batteries) are widely used in various fields due to their maintenance free, good sealing performance, safety and reliability characteristics. The following are their main application scenarios:
Power System
Substation DC system: As a backup power source for substation control, protection devices, and circuit breaker opening and closing, it ensures the stable operation of the power system during power outages.
Emergency power supply for distribution network: used as a backup power supply for distribution automation equipment and communication base stations, ensuring the continuity of power grid monitoring and communication.
communication field
Communication base station: provides backup power for base station equipment (such as transmission equipment, wireless transceivers) to cope with power outages or grid failures, ensuring uninterrupted communication signals.
Data center: As an energy storage unit of UPS (uninterruptible power supply), it provides temporary power to servers, network equipment, etc. in case of power interruption, avoiding data loss or service interruption.
Transportation
Railway and Rail Transit: Used as a backup power source for railway signal systems, emergency lighting inside trains, and communication equipment to ensure train safety and passenger service.
Auxiliary power supply for electric vehicles: In some models, it is used as a low-voltage auxiliary power supply to supply power to onboard electronic devices such as lighting, air conditioning, and control systems.
Industrial and Commercial Fields
Emergency lighting system: In places such as shopping malls, hospitals, and office buildings, it serves as a power source for fire emergency lights and safety exit indicator lights to meet emergency evacuation needs.
Industrial automation equipment: provides backup power for industrial control equipment such as PLCs (programmable logic controllers) and sensors to prevent production interruptions or equipment failures caused by power outages.
Security monitoring system: supports continuous operation of monitoring cameras and access control systems during power outages to ensure regional security protection.
Renewable Energy Systems
Solar and wind energy storage: used in conjunction with photovoltaic panels and wind turbines to store excess electricity and release it in the absence of light or wind, balancing the intermittency of renewable energy.
medical equipment
Hospital key equipment: provides backup power for ICU equipment, life support systems, operating room instruments, etc., ensuring that medical treatment is not affected by power outages.
Military and Aerospace
Military Communication and Equipment: Used as a backup power source for field communication base stations and radar systems, meeting the power reliability requirements in military missions.
Aerospace auxiliary power supply: used as a short-term backup power source in some small spacecraft or ground testing equipment (subject to special environmental requirements).
Other scenes
Ship and Ocean Engineering: As a backup power source for ship communication and navigation equipment, as well as an energy storage unit for ocean monitoring instruments.
Household emergency power supply: such as household backup power supply, emergency power supply box, used to meet the basic electricity demand in case of natural disasters or sudden power outages (such as lighting, small appliances).
summarize
The core application of valve regulated sealed lead-acid batteries lies in "backup power supply" and "energy storage", and their high reliability and maintenance free characteristics make them an important choice for ensuring the continuous operation of key equipment. When selecting, it is necessary to configure battery specifications reasonably based on factors such as capacity requirements, discharge time, and environmental temperature in specific scenarios.
