Modular intelligent power distribution cabinet

Abstract

The invention discloses a modular intelligent power distribution cabinet, and the cabinet comprises a cabinet body. The front side of the cabinet body is provided with a left door body and a right door body, and the left and right sides of the cabinet body are each provide with a side insulating plate. The top of the cabinet body is fixedly provided with a top insulating plate, and an insulating pedestal is disposed under the cabinet body. The interior of the cabinet body is sequentially provided with an upper modular cabinet body, a central modular cabinet body and a lower modular cabinet body, wherein the interior of the upper modular cabinet body is provided with an intelligent monitoring device. The interior of the central modular cabinet body is provided with an intelligent power distribution device. The interior of the lower modular cabinet body is provided with an intelligent dynamic compensation device. The intelligent monitoring device is connected with the intelligent power distribution device and the intelligent dynamic compensation device. The cabinet can achieve a power distribution function which integrates digital intelligent management, safety operation and automatic control and onsite local dynamic reactive compensation, so as to enable a power supply system to guarantee the power supply safety. The power distribution cabinet is reasonable in structural design,greatly improves the operability and safety, and is beautiful and elegant in overall appearance.

Description

technical field [0001] The invention relates to the technical field of power distribution cabinets, in particular to a modular intelligent power distribution cabinet. Background technique [0002] Power distribution cabinets are divided into power distribution cabinets, lighting distribution cabinets, and metering cabinets, and are the final equipment of the power distribution system. The power distribution cabinet is a general term for the motor control center. 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. They distribute the electric energy of a certain circuit of the upper-level power distribution equipment to the nearest load. This level of equipment shall provide protection, monitoring and control of the load. The existing power distribution cabinet has a simple structure, with a sin...

AI Technical Summary

Problems solved by technology

The existing structure of the power distribution cabinet is not beautiful in appearance, poor in operation safety, and requires professional electrician operation and maintenance

[0003] Moreover, the current transformer in the traditional power system is composed of a primary transformer and a secondary transformer (generally called an instrument transformer, which is installed in the collector), which is large in size and high in cost. It is difficult to install due to the limited installation space on site, and even Some branch circuits need to be modified before they can be installed; there are many branch circuits in the power consumption unit, and each circuit needs to be connected to current transformers, collectors, communication modules and other equipment, and the cost of equipment is high; in addition, the collectors need to be connected from various branch circuits on site Voltage signal, power outage operation is required during installation, which affects the production and operation of power consumers; due to the large number of access cables, professional wiring is required during construction, which makes installation difficult and heavy workload, high construction cost, and long construction period
