UPS system

Abstract

The invention discloses a UPS system. The UPS system comprises an inverter cabinet and a rectifier cabinet which are arranged in a split mode. The rectifier cabinet comprises a rectifier module mounting part, a rectifier transformer mounting part and a switch mounting part. The inverter cabinet comprises an inversion module mounting part and an inverter transformer mounting part. The rectifier module mounting part is electrically connected with the inversion module mounting part. The switch mounting part is arranged on one side, far away from the inverter cabinet, of the rectifier cabinet. Due to the fact that the inverter cabinet and the rectifier cabinet are arranged in the split mode, the size of a single cabinet body can be decreased, the UPS system can be transported and mounted conveniently, meanwhile, for the reason that the inverter cabinet and the rectifier cabinet have different heating amounts, the two cabinet bodies are respectively arranged, mutual heat diffusion between the two cabinet bodies can be avoided, the cooling system design can be carried out on each cabinet body independently, energy is saved, and meanwhile the heat dissipation purpose is achieved to the maximum degree.

Description

technical field [0001] The invention relates to the technical field of electrical appliances, in particular to a UPS system. Background technique [0002] UPS, that is, uninterruptible power supply, is a constant voltage and constant frequency uninterruptible power supply with an energy storage device and an inverter as the main component. It is mainly used to provide uninterrupted power supply to a single computer, computer network system or other power electronic equipment. When the mains input is normal, the UPS will stabilize the mains and supply it to the load. At this time, the UPS is an AC mains voltage stabilizer, and it also charges the battery inside the machine; At this time, the UPS will continue to supply 220V AC power to the load through the method of inverting the electric energy of the battery inside the machine immediately, so as to maintain the normal operation of the load and protect the software and hardware of the load from damage. UPS devices usually ...

AI Technical Summary

Problems solved by technology

[0003] With the increasing application of UPS systems, high-power UPS systems are gradually being promoted and applied, and the transformers used in high-power UPSs are relatively large, and thicker wires need to be used in high-power UPSs. And wiring requires a large space, which causes the volume of the high-power UPS system to be too large, and it is very inconvenient to install and transport.

[0004] In addition, the switch part and the customer terminal of the traditional high-power UPS system are arranged at the lower part of the cabinet. When wiring, it is usually necessary for the wiring personnel to operate in the pit or bend over for wiring. The wiring process is very inconvenient.
