A ring network cabinet and its control terminal

Abstract

The invention discloses a control terminal for a ring main unit, and the control terminal comprises a control circuit board, a terminal top case, and a terminal bottom case. The terminal top case and the terminal bottom case are oppositely attached to each other, and the interior of a space between the terminal top case and the terminal bottom case is provided with a control circuit board. The top of the terminal top case is provided with a first sliding projection, and a part, corresponding to the first sliding projection, of the bottom of the terminal bottom case is provided with a first sliding groove which can be in close fit with the first sliding projection. According to the invention, during installation, all control terminals can be interconnected through the close fit of the first sliding projection with the first sliding groove, and then are installed in a secondary box in a unified manner. The connection is convenient and simple, and the space is used efficiently. Moreover, the convenience in installation, management and extension of an auxiliary intelligent module of the ring main unit is improved, thereby facilitating the development of a large-scale ring main unit. The invention also discloses the ring main unit comprising the above control terminal, and the beneficial effects of the ring main unit are described above.

Description

technical field [0001] The invention relates to the technical field of power distribution equipment and electronic information, in particular to a control terminal of a ring network cabinet. The present invention also relates to a ring network cabinet including the above-mentioned control terminal. Background technique [0002] With the development of power electronics and power supply technology in China, more and more power facilities are widely used. [0003] Taking the ring network cabinet as an example, the ring network cabinet is a kind of electrical equipment in which high-voltage switchgear is installed in a metal or non-metal insulated cabinet or made into an assembled interval ring network power supply unit. In order to improve the reliability of power supply and enable users to obtain power from two directions, the power supply network is usually connected into a ring. This power supply method is referred to as ring network power supply, and the high-voltage swit...

AI Technical Summary

Problems solved by technology

However, the internal structure of the secondary box of the ring network cabinet is complex and changeable. In a slightly larger ring network cabinet, the scale of the control terminal in the subsidiary intelligent module is often large, resulting in complicated installation methods for each control terminal in the secondary box. The connection is messy and the management is inconvenient, which is not conducive to the development of the intelligent auxiliary modules of the ring network cabinet
