Power supply distribution cabinet

Abstract

The invention discloses a power supply distribution cabinet which is provided with a power supply monitoring device therein. The power supply monitoring device includes: a main circuit monitoring module which is connected to a main circuit power supply of the power supply distribution cabinet and is intended for monitoring a main circuit voltage and a main circuit current of the main circuit power supply and calculating electric quantity of the main circuit; a branch circuit monitoring module which is connected to a branch circuit power supply on the power supply distribution cabinet, and is intended for monitoring a branch circuit voltage and a branch circuit current of each branch circuit power supply and calculating the electric quantity of each branch circuit, wherein each branch circuit power supply is obtained by the distribution of the main circuit power supply; a processor which is intended for calculating power supply usage efficiency of the power supply distribution cabinet; a communication module which is in separate connection to a monitoring terminal and the processor, and is intended for transmitting the power supply usage efficiency of the power supply distribution cabinet to the monitoring terminal. Through the aforementioned methods, according to the invention, the power supply distribution cabinet implements monitoring of the power usage efficiency of the power supply distribution cabinet and sounds alarm when abnormity happens.

Description

technical field [0001] The invention relates to the technical field of communications, in particular to a power distribution cabinet. Background technique [0002] A data center refers to a group of centralized information processing, storage, transmission, exchange and management equipment in a physical space, which usually includes computer equipment, server equipment, network equipment and storage equipment. [0003] Because the data center has relatively high requirements on stability, in order to ensure the stable operation of the data center, it usually does not directly use the mains for power supply, but uses a set of special power distribution cabinets for power supply. The power distribution cabinet needs to ensure the output voltage and current stable. However, if the external power supply changes drastically and exceeds the controllable range of the power distribution cabinet, manual intervention on the power distribution cabinet is required. Therefore, the powe...

Problems solved by technology

However, the prior art power distribution cabinet usually only monitors the current, voltage and input circuit breaker status of the input power distribution cabinet, without setting the function of monitoring the upper and lower limit thresholds of current and voltage, but the current is too high or too low, and the voltage If it is too high or too low, it will have a great impact on the stability of the power supply of the data center. Therefore, there is no way for the power distribution cabinet in the prior art to provide more complete monitoring of the power distribution cabinet.
