Description

Technical Field

[0001] This utility model belongs to the field of emergency power supply technology, and in particular relates to a portable emergency power supply. Background Technology

[0002] Portable emergency power supplies are commonly used for information transmission equipment between railway stations. These portable emergency power supplies are designed to minimize the impact of power failures, shorten emergency response time, facilitate on-site operations, and ensure transportation safety when power supply failures occur in the information transmission equipment between railway stations.

[0003] Currently, when railway signal power system equipment fails, it cannot immediately supply power to inter-station information transmission equipment, necessitating an emergency power supply. An emergency power supply would significantly reduce the impact of on-site railway signal power system failures on inter-station information transmission equipment, thereby improving operational efficiency and resolving practical problems on-site. However, current emergency power supplies have a single, integrated casing, making operation inconvenient; furthermore, they only provide a single power supply circuit to the inter-station information transmission equipment and cannot be switched.
