An intelligent low-voltage distribution box

Abstract

The invention discloses an intelligent low-voltage distribution box. The intelligent low-voltage distribution box comprises a box body, an execution module, a control module, an electric quantity information detection module, an information acquisition terminal, a line circuit breaker, a line circuit breaker shunt release and a line circuit breaker auxiliary switch, wherein the execution module isconnected with the control module, and the execution module and the control module are arranged in the box body; the control module is connected with the information acquisition terminal by adoptinga wired or wireless mode; the line circuit breaker and the electric quantity information detection module are arranged at the line outlet side of a branch line of the low-voltage distribution box; theline circuit breaker is mounted on the branch line; the line circuit breaker shunt release is connected with the line circuit breaker; the electric quantity information detection module is mounted onthe branch line, and the electric quantity information detection module is mounted at the line outlet side of the line circuit breaker; and the electric quantity information detection module on the branch line is connected with the execution module. The low-voltage distribution box disclosed by the invention can effectively monitor the working state of a subordinate branch circuit and can performselective switching-off outage when a fault happens.

Description

technical field [0001] The invention relates to a low-voltage distribution box, in particular to an intelligent low-voltage distribution box. Background technique [0002] At present, domestic intelligent power distribution equipment is mainly based on high-voltage switchgear and low-voltage switchgear, which can collect and control various power parameters of power distribution equipment in substations and substations, such as the operating status of each switch and power parameters of lines, etc. However, it is impossible to effectively monitor and control the operating status of the distribution box equipment on the substation branch. The distribution box has multiple branch circuits to supply power to the lower-level electrical equipment, but when there is a problem with one of the electrical equipment, the upper-level substation cannot determine the specific branch circuit, and can only distribute the three-phase wires connected to the distribution box. This will not o...
