Building electrical automation power distribution box

Abstract

The invention provides a building electrical automation power distribution box, relates to the technical field of power distribution boxes, aims to solve the problems that when an existing building electrical power distribution box is used, a fire source cannot be automatically extinguished and the position where the fire source occurs cannot be accurately rescued in case of a spontaneous combustion phenomenon. The power distribution box comprises a main body, and the main body is of a rectangular structure, and the main body is a distribution box body. An ejecting piece is installed above a top bin, and a guide piece of the ejecting piece is embedded into the guide groove. The top bin is used for being arranged at the top end of the main body, so that when the device is used, the bearingplate can be controlled to be inserted into the inserting groove, then fire-fighting sand is added above the bearing plate, the fire-fighting sand can be blocked by the bearing plate to be used, and awax block is embedded into a round hole of the bearing plate, so that the fire-fighting sand does not flow downwards. When spontaneous combustion occurs in the main body, the temperature of a fire source in the main body is high, so that the flame can heat and melt the wax block in the circular hole at a proper position.

Description

technical field [0001] The invention belongs to the technical field of distribution boxes, and more specifically relates to a building electrical automation distribution box. Background technique [0002] The power distribution cabinet (box) is divided into power distribution cabinet (box), lighting distribution cabinet (box), metering cabinet (box), and is 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, and this level of equipment should provide protection, monitoring and control for the load. [0003] For example, the application numbe...
