Description

Fire protection device for electrical equipment

Technical Field

The invention relates to the technical field of electrical equipment fire protection devices, in particular to an electrical equipment fire protection device.

Background

Fires caused by power distribution cabinet decay, line aging, equipment short circuit, improper operation of electric equipment and the like in enterprises are the most common. The main reason for this is that the power protection devices do not provide a good protection function and cannot effectively protect the devices and control the resulting fire source when an electrical short occurs. General metal power switch board short circuit very easily after electrical equipment is ageing causes the root cause of conflagration, and sealed facility is not good also can make power cabinet inside advance grey, and some corrosive gases such as intaking cause the internal component to age with higher speed. The nonmetal waterproof, dustproof, fireproof and anticorrosive distribution box has good protection effect on circuits and electrical equipment. When larger electrical equipment such as a transformer, an electrical cabinet and the like catches fire, the circuit needs to be disconnected firstly, and then fire extinguishing treatment is carried out. Existing electrical equipment is equipped with circuit breakers that open the circuit when the circuit is overloaded. However, even if the circuit of the electrical equipment is disconnected after the fire is started, the electrical equipment is still in a burning state before the fire extinguishing measures are taken by the power workers, so that not only can electrical elements inside the electrical equipment be seriously damaged, but also objects near the electrical equipment are easily ignited to cause a wider fire disaster, and the potential safety hazard is larger. Therefore, the automatic fire extinguishing device mainly comprises four parts, namely a detector (a heat energy detector, a flame detector and a smoke detector), a fire extinguisher (a carbon dioxide extinguishing device), a digital temperature control alarm and a communication module. Can carry out remote monitoring and control to the real-time temperature change in the fire prevention area, alarm state and fire extinguisher information through the digital communication module in the device, not only can the various states of remote monitoring automatic fire extinguishing apparatus, can master the real-time change in the fire prevention area in addition, can furthest reduce life and loss of property when the conflagration takes place, simultaneously the usable purpose that reaches quick fire extinguishing of blocking gas.
