Power transformation cabinet with fault self-checking function

Abstract

The invention provides a power transformation cabinet with the fault self-checking function. The power transformation cabinet is high in fault handling efficiency and low in operational risk. The power transformation cabinet comprises a voltage transformation module, a high-voltage module, a low-voltage module, a first external connection terminal, a second external connection terminal, a fault detection module, a storage module, a control module, an alarm module, a display module and an independent power source. The voltage transformation module is respectively connected with the high-voltage module and the low-voltage module, the first external connection terminal is connected with the high-voltage module and used for externally transmitting or receiving high-voltage electricity, the second external connection terminal is connected with the low-voltage module and used for externally transmitting or receiving low-voltage electricity, the fault detection module is respectively connected with the voltage transformation module, the high-voltage module and the low-voltage module for fault detection, a fault factor contrast data base is preset in the storage module and used for storing factors which cause faults and correspond to various fault expressive forms and the corresponding relations, and the control module is respectively connected with the fault detection module, the storage module, the alarm module and the display module.

Description

technical field [0001] The invention relates to the technical field of power transformation, in particular to a power transformation cabinet with a fault self-checking function. Background technique [0002] Substation, as the name suggests, is the place and place where the voltage is changed, and it is the place where the voltage and current of electric energy are transformed, concentrated and distributed in the power system. In order to ensure the quality of electric energy and the safety of equipment, voltage adjustment, power flow (flow direction and distribution of voltage, current and power in each node and branch in the power system) control and power transmission and distribution lines and Protection of major electrical equipment. [0003] The box-type substation that appears today is referred to as a substation. The substation is equivalent to a simplified version of the substation. It is small in size and more flexible in use. The appearance of the substation cab...

AI Technical Summary

Problems solved by technology

The appearance of the substation cabinet is conducive to the remote transmission of high-voltage electricity and provides convenience for power transmission. However, the high density of equipment inside the substation cabinet greatly increases the difficulty of maintenance and repair, and the substation cabinet is a strong current device. There is a certain safety risk when personnel operate it
