Description

Intelligent power distribution box and power supply equipment for temporary power utilization of construction site Technical Field The utility model relates to the technical field of power equipment, in particular to an intelligent power distribution box and power supply equipment for temporary power utilization in a construction site. Background The safety and management efficiency of temporary electric equipment are one of key factors for ensuring the smooth progress of engineering in a construction site of the construction engineering. The traditional three-level distribution box is used as core equipment for power distribution, and is mainly composed of a total distribution switch, a fuse, an ammeter, a voltmeter and the like, but mainly depends on manual operation and a basic protection device, lacks intelligent, automatic and data management capability and has various limitations. Firstly, the accuracy and timeliness of manual monitoring are affected by personnel experience and responsibility, erroneous judgment or missed judgment easily occurs, and particularly in a complex construction site with frequent power load change, emergency is difficult to deal with, and potential safety hazard is increased. Secondly, the construction site environment is complex, the traditional distribution box is difficult to respond in time when current is overloaded or a line fails, equipment overheat, fire disaster or electric shock accidents can be possibly caused, and early warning and automatic power cut-off cannot be performed due to lack of an intelligent protection mechanism. In addition, the traditional block terminal can't realize remote monitoring and control, and the managers need to go to the field operation in person, and inefficiency, and lack data acquisition and analysis function leads to electric power resource waste and construction cost increase.
