Description

Display assembly for intelligent power distribution cabinet and low-voltage intelligent power distribution cabinet

Technical Field

The embodiment of the disclosure generally relates to intelligent power distribution cabinets, and particularly relates to state display of working components in the intelligent power distribution cabinets.

Background

Intelligent power distribution cabinets are widely used in power systems, for example, low-voltage intelligent power distribution cabinets are located at the end of power room energy sources, comprehensively collect all energy data and provide power monitoring. The intelligent power distribution cabinet is internally provided with a communication host which is configured to collect data of bottom-layer equipment and transmit the data to the background control system through a network, so that the real-time monitoring and the effective management of the running quality of the whole power distribution system are realized through the background control system.

However, background monitoring causes much inconvenience in field maintenance of the intelligent power distribution cabinet. For example, when the intelligent power distribution cabinet normally works, a power maintenance field worker cannot touch the space in the cabinet, so that the working state of internal components (such as a communication host) of the intelligent power distribution cabinet cannot be seen. In this case, the power maintenance staff can only obtain the relevant maintenance information from the background monitoring software through the control center, which results in high maintenance cost. In addition, in some intelligent power distribution cabinet products, an intelligent display screen is also installed in the intelligent power distribution cabinet to provide on-site data display, however, the intelligent display screen will obviously increase the manufacturing cost of the intelligent power distribution cabinet.

It is desirable to be able to improve the state of the art intelligent power distribution cabinets to provide a low cost display scheme for intelligent power distribution cabinets.
