Intelligent integrated low-voltage power distribution cabinet

Abstract

The invention discloses an intelligent integrated low-voltage power distribution cabinet, and relates to the technical field of power distribution cabinets, the intelligent integrated low-voltage power distribution cabinet comprises a cabinet body, and the cabinet body is internally provided with a bus chamber, a metering chamber, a control chamber, a fine compensation unit and an isolation chamber from top to bottom in sequence; a metering mutual inductor is arranged in the metering chamber, a draw-out type frame circuit breaker is installed in the control chamber, fine compensation equipment is arranged in the fine compensation unit, the upper end of the fine compensation equipment is fixedly connected with a display window, a first output end of the draw-out type frame circuit breaker is connected with one end of a main busbar, and a second output end of the draw-out type frame circuit breaker is connected with the other end of the main busbar. The other end of the main busbar passes through the metering chamber and is inserted into the bus chamber; the second output end of the draw-out type frame circuit breaker is connected with one end of the branch busbar, and the other end of the branch busbar is inserted into the fine compensation unit. A traditional wire inlet cabinet and a traditional capacitance compensation cabinet are fused, upgraded and improved into a mode that the fine compensation device is additionally arranged on the wire inlet cabinet, one capacitance cabinet can be reduced, and the purpose of saving space is achieved.

Description

[0001] The present invention is a divisional application titled "Intelligent Integrated Fine Compensation Low-Voltage Power Distribution Cabinet", wherein the application number of the parent application is 202010162747.2, and the application date is 2020.03.10. technical field [0002] The invention relates to the technical field of power distribution cabinets, in particular to an intelligent integrated low-voltage power distribution cabinet. Background technique [0003] In the low-voltage power distribution part, there are incoming line cabinets, outgoing line cabinets and capacitor compensation cabinets. In capacitive compensation, the capacitor and load are connected in parallel. Capacitors are the same as electric banks. When the load increases, due to the internal resistance of the power supply, the output voltage of the power supply will drop, and the two ends of the capacitor must maintain the original voltage, that is, part of the current in the capacitor will flow...

AI Technical Summary

Problems solved by technology

[0004] The traditional incoming line cabinet and the capacitor compensation cabinet are two independent cabinets, and correspondingly need to occupy two positions. Existing manufacturers cannot achieve the perfect combination of the two cabinets, and can only make the two components used together, They are respectively installed inside the two cabinets, which not only greatly increases the floor space, but also has the disadvantage of being inconvenient for management and maintenance.
