Abstract

The invention relates to industrial emergency power supplies, in particular to a special operational power supply for a power box transformer substation. The power supply comprises a case used for mounting internal components and provided with a port, a storage battery charging management module connected with a storage battery for charging, a power supply input switching module connected with two alternating current output circuits and used for controlling switching, an inverted output power supply module for controlling the storage battery to perform emergency power supply output, a bypass module for controlling alternating current output circuit and storage battery power supply switching, and a temperature control module for regulating temperature. The special operational power supply for the power box transformer substation provides a wide industrial running environment, the efficiency is improved, each module is performed with partitioning temperature control, and the stand-by power consumption is less than 2W; the special operational power supply provides the impact inductive load loading ability, and the maximum output power can arrive at 200% in one second; the charging voltage can be compensated according to the environment temperature of a lead-acid storage battery, and the battery working state can be detected; the special operational power supply uses online switching to realize automatic hot standby and is different from an online type or backup type UPS.

Description

technical field [0001] The invention relates to an industrial backup power supply, in particular to a special operating power supply for a power box transformer. Background technique [0002] At present, the backup power supply of the electric AC operating system usually uses an ordinary UPS power supply. This power supply is suitable for use as a backup power supply system after a computer system or digital device is powered off. It is divided into two types: online type and backup type. The common problems are: [0003] 1. Existing products do not have industrial operating conditions. Generally, the operating conditions of this type of products are -5°C to 40°C, humidity 20% to 90%, and the industrial environment requirements are -25°C to 60°C. [0004] 2. Existing products do not have overshoot capability, and cannot carry loads with impact loads, such as motors, electromagnetic coil loads, etc.; [0005] 3. Existing products do not have intelligent battery maintenance f...
