TECHNICAL FIELD

[0001] The utility model relates to the technical field of UPS power supply, specifically is a novel UPS power cabinet. BACKGROUND

[0002] UPS, uninterruptible power supply equipment, refers to the power supply equipment that does not interrupt because of short-term power failure, can always supply high-quality power supply, effectively protects precision instrument, has the effect of stable voltage.

[0003] UPS is a power protection device containing energy storage device, inverter as the main element, voltage and frequency stabilization output from the basic application principle. Mainly by rectifier, battery, inverter and static switch several parts. 1) rectifier: rectifier is a rectifier device, simply said is the device that converts alternating current (AC) into direct current (DC). It has two main functions: first, AC (AC) is changed into direct current (DC), and after filtering, it is supplied to the load, or to the inverter; Second, provide charging voltage for the battery. Therefore, it also plays a role of a charger; Battery: the battery is used as a storage device for UPS to store electrical energy, which is composed of a number of batteries in series, and its capacity determines the time of maintaining discharge (power supply). Its main function is: 1 when the city power is normal, the electrical energy is converted into chemical energy and stored in the battery. 2 when the city power fails, the chemical energy is converted into electrical energy to provide for the inverter or load; Inverter: inverter is a device that converts direct current (DC) into alternating current (AC). It is composed of inverter bridge, control logic and filter circuit; Static switch: static switch, also known as static switch, is a non-contact switch, which is composed of two controllable silicon (SCR) in reverse parallel, and its closing and opening are controlled by logic controller. It is divided into conversion type and parallel type. The conversion type switch is mainly used in the system of two power supply, its function is to realize the automatic switching from one way to another; Parallel switch is mainly used for parallel inverter and city power or multiple inverters.
