Description

AUTOMATIC COMMUNICATION SYSTEM FOR LOCAL SUPPRESSION OF RISING TEMPERATURE OR FIRE EXTINGUISHING IN POWER CONNECTED ELECTRICAL EQUIPMENT

Field of the Invention

The invention relates to the protection of electrical equipment such as sockets, switches, electrical appliances, extension cords, connectors and other electrical equipment connected to equipment connected to a power source, for example a distribution box where the temperature can rise or a fire may occur.

State of the art

Unwanted thermal phenomena can occur in lighting circuits, sockets or circuits with connected devices such as electric ovens or hobs, the negative effects of which can lead to the gradual loss of functionality or destruction of these devices, and in extreme cases even to a fire. This can be caused by various processes such as unwanted chemical reactions, electrical short circuits, overheating of the system, formation of an electric arc, combustion of working fluids, etc.

Known protections for sockets or light circuits of electric distribution boxes from the state of the art are so-called arc protections, which have the ability to mitigate the effect of arcing in the event of a failure by disconnecting from the electrical source. Arc protectors, however, have no extinguishing capability or the ability to prevent temperature rise in switchboards and their lighting, sockets and other circuits.

Said transmitter, which comprises a carrier of a cooling medium with extinguishing effects, in which an opening/nozzle is formed due to the increase in temperature, through which the cooling medium with extinguishing effects escapes into the area of the protected device, where it cools the rise in temperature or extinguishes the resulting fire.

System activation is from 30°C in the protected area.

Disconnecting the protected area from the power source prevents the electrical short circuit from happening again.

The receiver shows digital or analog signalling/initiation, i.e., the quenching coolant is discharged from the quenching coolant carrier arranged in the transmitter, and due to the rise in temperature, this carrier breaks, the quenching coolant is released into the protected area, e.g. socket, the transmitter sends a signal to the receiver, whereby the protected area, such as the socket or other electrical device, in which the damaged refrigerant carrier is located, is precisely identified and the transmitter and refrigerant carrier can be easily replaced. .

Installing an automatic communication system for local temperature rise suppression or extinguishing in electrical equipment connected to a power source is very easy.

The dimensions of the transmission system are adapted to the size of the protected areas, such as sockets, switches, electrical appliances, extension cords, connectors and other electrical equipment.
