Power system secondary equipment multifunctional power adapter device

Abstract

The invention discloses a multifunctional power supply adaption device of a power system secondary device. The multifunctional power supply adaption device comprises a power supply mother board and at least two power supply daughter boards, wherein the power supply mother board and the power supply daughter boards are connected through pins and pin holes, the power supply daughter boards are different in model, and the power supply mother board comprises an EMC filtering circuit, a PFC power circuit and an output module. The EMC filtering circuit is connected with the PFC power circuit, the PFC power circuit is connected with the output module through an under-voltage circuit, the output module comprises a 24V output device, a 5V output device, a + / -15V / 12V output device and a + / -15V and + / -12V conversion output device which are independent in power and feedback control. The multifunctional power supply adaption device comprises the power supply mother board and multiple power supply daughter boards, achieves a 1+N type combination structure, can achieve multipath output and has functions of output short-circuit protection, self recovery and power portion temperature protection.

Description

Technical field: [0001] The invention relates to a power adapter, in particular to a multifunctional power adapter device for secondary equipment in a power system. Background technique: [0002] With the continuous expansion of the scale of the power grid, the contradiction between the increase of maintenance equipment and the supplement of spare parts has become increasingly prominent. The specificity, pre-control and scientificity of the management of secondary equipment defects are not enough. Once the secondary equipment has problems, the constraints There are many factors of response speed, which directly affect the safe and stable operation of the power grid. [0003] According to the defect analysis of secondary equipment, there are many faults in the power supply of secondary equipment. Due to the large number of equipment manufacturers and the inconsistency of models, a large number of equipment power supply spare parts are not easy to purchase and apply, and there...

Problems solved by technology

[0002]With the continuous expansion of the power grid scale, the contradiction between the increase of maintenance equipment and the supplement of spare parts has become increasingly prominent, and the management and pre-control of secondary equipment defects , The scientific strength is not enough. Once the secondary equipment has problems, there are many factors that restrict the response speed, which directly affects the safe and stable operation of the power grid.

[0003]According to the defect analysis of the secondary equipment, there are many secondary equipment power failures. It is not easy to purchase and apply, lacks a wide and unified multi-functional emergency power supply to quickly deal with defects, and lacks a protection device power module that can adapt to various models
