Problems solved by technology

In the case of high power, a high-power fan needs to be installed for internal heat dissipation. In addition, the emergency power host with a drawer design has less internal space and more internal wiring, which is not conducive to heat dissipation.

Embodiment Construction

[0017] In order to facilitate the understanding of those skilled in the art, the present invention will be further described below in conjunction with the accompanying drawings.

[0018] see Figure 1-3 , the system is mainly composed of input circuit breaker QFA, contactors KM1, KM2, and interlocking between them, rectifier charger, inverter inverter module, battery pack, output circuit breaker QF, output filter network, etc. The utility power enters the emergency power supply through the circuit breaker QFA, and the output of the QFA is divided into two circuits, one for output through the contactor KM1, and the other for charging the battery pack through the rectifier charger module. The control unit judges whether the mains power is out of power through the mains power detection. If the mains power is normal, the contactor KM1 will be closed, and the mains power will be directly output through the contactor KM1 bypassed by the emergency power supply; if the mains power fai...

Abstract

The invention belongs to the field of emergency power supply, particularly to a back type emergency power supply. The back type emergency power supply is mainly formed by an electric supply input portion, a rectification charging module, an inverting module, a driving module, a control module, an output transformer, an output filter, an alternating current contactor, a follow current capacitor, a control unit and a detection unit; the inverting module and the control module are arranged inside a main machine module; the inverting module and the follow current capacitor are connected through a copper bar; the control unit and the detection unit are assembled in a drawer type installation type; the follow current capacitor is arranged at the second layer on the lower portion of the main engine; the control unit which is arranged at a first layer position at the upper end of the follow current capacitor is isolated by an insulating baffle board; four fans are installed at the lower end of the main machine module. According to the back type emergency power supply, the main machine module is designed to be in a back type, the emergency power supply can be stably and reliably operate under large-power load, and later maintenance under the condition that the main machine module is large is convenient.

Description

technical field [0001] The invention belongs to the field of emergency power supplies, in particular to a back-type emergency power supply. Background technique [0002] The main function of the emergency power supply is to provide emergency power for the load when the normal mains fails or fails. The power of the emergency power supply is generally several kilowatts to tens of kilowatts, and the low-power emergency power supply is suitable for a drawer design. At present, the places where emergency power supply is applied to power and fire-fighting equipment are gradually increasing. If the drawer design is still adopted, there will be the following disadvantages: [0003] The height of the high-power emergency power supply cabinet is generally about 2 meters. If the drawer design is still adopted, the position of the host module will be higher, which is not conducive to on-site operation. After increasing the power of the emergency power supply, the weight and volume of ...
