Intelligent fire-proof power distribution cabinet

Abstract

The invention discloses an intelligent fire-proof power distribution cabinet. According to the intelligent fire-proof power distribution cabinet, the prevention, alarm and immediate fire-extinguishingof the inner firing situation of the power distribution cabinet are achieved. The intelligent fire-proof power distribution cabinet comprises a single chip microcomputer control module, a temperaturesensor, a smoke sensor, an open-fire sensor, an input circuit module, a power supply module, an output circuit module and a fire-extinguishing module, the temperature sensor is used for collecting and monitoring temperature data in the power distribution cabinet, the smoke sensor is used for collecting and monitoring the smoke concentration in the power distribution cabinet, the open-fire sensoris used for sensing whether open fire exists or not, and inputting the data to the input module correspondingly, when the single chip microcomputer detects a fire, the fire-extinguishing module is immediately controlled to extinguish the fire through the output circuit module, and thus the alarm and fire extinguishing of firing in the power distribution cabinet are achieved.

Description

technical field [0001] The invention relates to an intelligent fireproof power distribution cabinet, which belongs to the electric field. Background technique [0002] As the main component of the power distribution room, the power distribution cabinet directly affects the safety of the power supply and distribution system and power users, and also plays the role of monitoring, control, measurement and on-off protection for the power supply and distribution equipment in the power supply and distribution system. . With the increase of social production and people's living demand for electricity, people's requirements for the safety of power distribution cabinets are also increasing. Moreover, the power distribution cabinet is often installed in a dangerous workplace with conductive dust or flammable and explosive gases. Once the power distribution cabinet catches fire, it will cause irreparable consequences. [0003] The reason for the fire in the power distribution cabinet...

Problems solved by technology

In addition, the leakage spark generated at the leakage point can also cause fire; short-circuit fire: when the short circuit suddenly reduces the resistance, the current suddenly increases, and the instantaneous heat generation is also very large, which greatly exceeds the heat generation when the line is working normally. And it is easy to generate strong sparks and arcs at the short-circuit point, which can not only make the insulating layer burn quickly, but also melt the metal, causing nearby flammable and combustible materials to burn, causing a fire; overload fire: when the wire is overloaded, the speed of the wire is accelerated. Insulation aging and deterioration
