Power distribution cabinet with lightning protection and remote monitoring functions and power distribution system

Abstract

The invention provides a power distribution cabinet with lightning protection and remote monitoring functions and a power distribution system. The power distribution cabinet comprises: a fixed base, wherein the upper surface of the fixed base is fixedly connected with a power distribution cabinet main body, the upper surface of the power distribution cabinet main body is fixedly connected with a cabinet top cover, the upper surface of the cabinet top cover is fixedly connected with a lightning arrester, the inner top wall of the power distribution cabinet main body is fixedly connected with a grounding down lead, the front surface of a mounting plate is provided with power distribution equipment, a single-chip microcomputer, a wireless communication module and a data memory, and the single-chip microcomputer is connected to the grounding down lead through a divider resistor, an AD conversion circuit and a transient diode to obtain lightning signals. According to the invention, rainwater can be prevented from entering the power distribution cabinet main body by arranging the cabinet top cover; by arranging the lightning arresters, direct lightning strokes can be received by the lightning arresters in rainy and thunder days if the lightning falls into the range of the power distribution cabinet main body; and the lightning strokes received by the lightning arresters can be transmitted to the underground by arranging the grounding down lead, so that the lightning protection effect is achieved.

Description

technical field [0001] The invention relates to the technical field of power distribution cabinets, in particular to a power distribution cabinet and a power distribution system with functions of lightning protection and remote monitoring. Background technique [0002] Power distribution cabinets (boxes) are divided into power distribution cabinets (boxes), lighting distribution cabinets (boxes), and metering cabinets (boxes), which are the final equipment of the power distribution system. The power distribution cabinet is used in the occasions where the load is relatively scattered and there are few circuits; the motor control center is used in the occasions where the load is concentrated and there are many circuits. [0003] Some power distribution cabinets will be used in the field environment, that is, there is no power distribution room and used in the open air. The outdoor power distribution cabinet is used as a power transfer device, which can distribute the power of...

AI Technical Summary

Problems solved by technology

Because it is used outdoors, if it encounters thunderstorm weather, it will be struck by lightning, which will cause damage to the power distribution cabinet and cause losses

If the monitoring is not timely, it is impossible to find out in real time whether the outdoor power distribution cabinet is struck by lightning, or whether the failure is caused by external environmental factors
