Switching system for supplying power to emergency power supply

Abstract

The invention relates to a switching system for supplying power to an emergency power supply. The switching system comprises a switching system, wherein interior of the switching system comprises an ATS automatic changeover switch, a controller module, a current detection chip, a main power supply and an emergency power supply, wherein the ATS automatic changeover switch is used for switching selection between connection circuits, the controller module is connected with the ATS automatic changeover switch and is used for controlling switching operation of the ATS automatic changeover switch, the current detection chip is connected with the controller module and is used for detecting current intensity in the circuit, the main power supply is connected with the current detection chip and isused for providing electric energy, and the emergency power supply is connected with the current detection chip and is used for providing electric energy for the main power supply when power is in failure. In the switching system for supplying power to the emergency power supply, automatic switching between the main power supply and the emergency power supply is performed, power supply is timely ensured, equipment damage and personal safety are prevented, switching is performed when electric quantity between the main power supply and the emergency power supply is relatively low, protection isachieved between the main power supply and the emergency power supply, loss generated on the power supplies when the electric quantity is excessively low is prevented, and the application safety of the circuit and the power supplies is protected.

Description

technical field [0001] The invention belongs to the field of battery management systems, and in particular relates to a switching system for backup power supply. Background technique [0002] Buildings with a higher level of power supply must be able to provide sufficient power under normal conditions, and have sufficient backup power when the normal power supply fails. When the building encounters an emergency (such as: fire, earthquake, etc.), There must also be emergency power to ensure disaster relief and evacuation. Any building needs to consume a lot of electricity to be able to use and operate normally. The main source of electricity consumed by buildings is the national or regional power grid. Supplementary power supply, in many cases, diesel generator sets and battery energy storage equipment will be set up as backup and emergency power supply. [0003] At present, for equipment that does not allow power failure, the switch between the main power supply and the ba...

Problems solved by technology

In this way, the switching between the main power supply and the backup power supply is simple, but there are disadvantages such as cumbersome operation and untimely switching; turn, and even the power of the backup power supply is reversed to the main power circuit, which may damage the equipment or endanger personal safety.
