Power distribution cabinet of intelligent power utilization system for large and medium-sized residents

Abstract

The invention provides a power distribution cabinet of an intelligent power utilization system for large and medium-sized residents, which comprises a power distribution cabinet, a monitoring sensor and a communication device, and is characterized in that the shape of the power distribution cabinet is a rectangular shell, a rainproof cover is arranged at the top of the power distribution cabinet, a base is arranged at the bottom of the power distribution cabinet, a cabinet door is arranged on the front surface of the power distribution cabinet, and the communication device is arranged on the side surface of the power distribution cabinet; a rainproof cover is arranged in the power distribution cabinet, a monitoring sensor is arranged in the rainproof cover, a probe of the monitoring sensor penetrates through the top surface of the power distribution cabinet and is arranged at the top of the inner side of the power distribution cabinet, and the monitoring sensor comprises a power receiver, a temperature sensor, a humidity sensor and a monitoring probe. And moreover, an abnormal instruction is sent out from the external monitoring PC, and a maintainer can check the power distribution cabinet during maintenance, so that the fire extinguishing efficiency of the power distribution cabinet is greatly improved, timely fire extinguishing is realized, and damage to the interior of the power distribution cabinet caused by a fire disaster is avoided.

Description

technical field [0001] The invention belongs to the technical field of power distribution cabinets, and in particular relates to a power distribution cabinet for an intelligent power consumption system for large and medium-sized residents. Background technique [0002] Power distribution cabinets are divided into power distribution cabinets, lighting distribution cabinets, and metering cabinets, which are the final equipment of the power distribution system. Power distribution cabinet is a general term for motor control center. The power distribution cabinet is used in situations where the load is relatively scattered and there are few circuits; the motor control center is used in the situations where the load is concentrated and there are many circuits. They distribute the electrical energy of a certain circuit of the upper-level power distribution equipment to the nearest load. This class of equipment shall provide protection, monitoring and control of the load. [0003...

AI Technical Summary

Problems solved by technology

[0003] The high-voltage power distribution cabinet is generally sealed due to the consideration of the environment and safety needs. The high-voltage power distribution cabinet has the characteristics of long-term continuous operation. The high-voltage power distribution cabinet is generally placed in the open air, so the external weather conditions may affect the interior of the power distribution cabinet environment, because the electrical components inside the power distribution cabinet operate continuously for a long time, the electrical devices in the cabinet will generate heat during operation, and the heat will affect the rubber insulating material in the power distribution cabinet, resulting in accelerated aging and insulation Performance decline, when severe aging may lead to short circuit of internal electrical components, resulting in accidents, outdoor power distribution cabinet due to internal electrical components in operation due to self-loss heating and environmental factors such as sunshine, making the temperature inside the cabinet rise, serious conditions will cause the circuit breaker to trip and short the

And the power distribution cabinet is noisy at night, which affects the lives of nearby residents
