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

Embodiment approach

[0063] As an embodiment of the present invention, the single-chip microcomputer sends the operation data of the power distribution cabinet to the power distribution data control terminal, and the power distribution data control terminal can display it to the monitoring personnel and forward it to the monitoring server at the same time. The operation data of the power distribution cabinet can be the state of the internal switch linkage data of the power distribution cabinet, the action data of the thermal relay, the action data of the protection device, the operation data of the lightning protection device, the operation data of the electric energy detection device, the operation data of the voltage and current detection device and Operating data of the control loop, etc. The operating data of the power distribution cabinet can be communicated and transmitted through data in the form of JSON. In this way, after the power distribution data control terminal receives the lightning...

Abstract

The invention provides a power distribution cabinet and a power distribution system with lightning protection and remote monitoring functions, including: a fixed base; the upper surface of the fixed base is fixedly connected with the main body of the power distribution cabinet, and the upper surface of the main body of the power distribution cabinet is fixedly connected with the top cover of the cabinet The upper surface of the top cover of the cabinet is fixedly connected with an air-termination device; the inner top wall of the main body of the power distribution cabinet is fixedly connected with a grounding down-conductor, and the front of the installation board is provided with power distribution equipment, a single-chip microcomputer, a wireless communication module and a data storage device; The single-chip microcomputer is connected to the grounding down-conductor through the voltage dividing resistor, AD conversion circuit and transient diode to obtain the lightning signal; by setting the top cover of the cabinet, it can prevent rainwater from entering the main body of the power distribution cabinet; In a thunderstorm, if there is a lightning strike within the main body of the power distribution cabinet, the direct lightning strike can be received through the lightning receptor, and the lightning received by the lightning receptor can be transmitted to the ground by setting the grounding down conductor, so as to achieve the effect of lightning protection.

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...
