Protection device of UPS power supply cabinet

Abstract

The invention discloses a protection device of a UPS power supply cabinet. The device comprises a power supply cabinet main body, the front end and the rear end of the power supply cabinet main body are fixedly connected with power supply cabinet doors. A heat dissipation opening is formed in the outer side surface of the power supply cabinet door; the inner end of the heat dissipation opening ofthe power supply cabinet main body is fixedly connected with a heat dissipation fan; a dustproof plate is arranged in the heat dissipation opening; a fixed shaft is fixedly connected to the dustproofplate and the inner wall of the interior of the heat dissipation opening; a limiting baffle is fixedly connected to the inner port of the heat dissipation opening, a reset spring is fixedly connectedto the surface of the outer end of the limiting baffle, the other end of the reset spring is fixed to the inner side of the bottom end of the dustproof plate, the dustproof plate is perpendicular to the inner wall of the heat dissipation opening, and the dustproof plate covers and is fixed to the outer port of the heat dissipation opening. Through the designed dustproof plate, the dustproof platecovers the outer side port of the heat dissipation opening, the heat dissipation opening is protected against pollution of dust and the like, and the dustproof plate rotates and inclines towards the outer side through the fixing shaft, so that normal air exhaust and heat dissipation of the heat dissipation opening are not affected.

Description

technical field [0001] The invention belongs to the technical field of electrical machinery equipment, and in particular relates to a protection device for a UPS power supply cabinet. Background technique [0002] UPS is an uninterruptible power supply. It is a system device that connects the battery to the host and converts direct current into commercial power through a module circuit such as the host inverter. It is mainly used for powering a single computer, computer network system or other power electronic equipment such as electromagnetic Valves, pressure transmitters, etc. provide stable and uninterrupted power supply. 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 voltage stabilizer, and at the same time It also charges the battery inside the machine; when the utility power is interrupted, the UPS will immediately supply the DC power of the battery to the load through the inverter switching me...
