Modularized power supply device

Abstract

A modularized low-voltage distribution line power supply device comprises at least one insulating base module with a concave cavity, the insulating base module is provided with at least one wire inlet end, at least one wire outlet end and connecting conductors, the number of the connecting conductors is equal to the number of the wire inlet ends and the number of the wire outlet ends, and the connecting conductors are connected with the wire inlet ends and the wire outlet ends. The device further comprises a monitoring box module arranged corresponding to the concave cavity, an electronic controller is arranged in the monitoring box module, a contact conductor is arranged on the monitoring box module, the monitoring box module and the concave cavity are correspondingly arranged in a pluggable mode, and the contact conductor is in conductive contact with the connecting conductor. The electronic controller of the power supply device can be independently replaced in a live-line mode, an insulating base module connected with a primary conductive loop does not need to be detached, power supply continuity is guaranteed, equipment maintenance cost and labor cost are reduced, reliability of a monitoring function and a communication function is improved, and secondary upgrading and reconstruction are easy.

Description

technical field [0001] The invention relates to a modular low-voltage distribution line power supply device. Background technique [0002] As the State Grid continues to promote the "three-type and two-network" plan, various products in the power system are continuously upgraded and upgraded, and functions such as line, equipment monitoring, remote communication, data processing edge computing and display are continuously added to low-voltage products and equipment. Electronic and intelligent products and equipment have become an inevitable trend. [0003] In the previous patent "A kind of intelligent terminal block 202010818613.1", although the consideration based on system integration is solved, the streamlining and merging of low-voltage products solves problems such as crowded internal space of equipment, difficult structural design, and poor heat dissipation. However, there is still a problem that the service life of the structural module and the service life of the el...

Problems solved by technology

[0005] In addition, the modularity of each component in the existing circuit system is insufficient, and the internal structure is likely to be confused when the function is increased or decreased. It is necessary to improve the modularization level of the circuit system to adapt to the access of different functional modules.
