The invention relates to the protection of electrical equipment such as sockets, switches, electrical appliances, extension cables, connectors, and other electrical equipment which are coupled to equipment connected to an electrical power source, for example electrical distribution box, where temperature can rise or fire can occur.
In lighting circuits, socket circuits or circuits with connected appliances such as electric ovens or hotplates, undesirable thermal phenomena can occur, the negative effects of which can lead to a gradual loss of functionality or destruction of these devices and in extreme cases can even lead to fire. This can be caused by various processes such as undesirable chemical reactions, electrical short circuits, overheating of the system, formation of the electric arcing, burning of operating fluids, etc.
The known protections for socket or light circuits of electrical distribution boxes from state of art are so-called arc protectors, which have the ability to mitigate the effect of a fault arc by disconnecting from the electrical source. However, arc protectors do not have the extinguishing capability or the ability to prevent rising temperatures in switchboards and their lighting, socket and other circuits.
The above deficiencies are eliminated by an automatic communication system for local suppression of rising temperature or fire suppression in electrical equipment connected to an electrical power source, the essence of which is that it consists of a transmitter arranged in at least one protected electrical device, such as electrical sockets, switches, electrical appliances, extension cords, connectors, connected to electrical circuits, and a receiver arranged at the location of the electrical power source, for example in an electrical distribution box.
Wherein the transmitter includes a cooling medium carrier with a fire extinguishing effect, which is closed by a first terminal on one side, under which a communication control unit with a battery is arranged, and on the other side the cooling medium carrier with a fire extinguishing effect is closed by a second terminal.
The transmitter is also powered externally. The cooling medium carrier with extinguishing effect is made of polymer materials, it is a low pressure device up to 1 MPa. The transmitter's communication control unit contains a temperature or smoke sensor or a light spectrum sensor, an RF transmitter for communication e.g. WIFI, Bluetooth, LAN and others, a pairing button for connecting the transmitter's wireless communication with the receiver, arranged in an electrical distribution box in which a protected area, e.g. a socket, is connected in the electrical circuit, and the communication control unit contains a control LED for setting the pairing of the transmitter with the receiver.
Wherein the receiver that is arranged in a device with a power supply, such as a electrical distribution box, is compatible with the DIN rail. The receiver enables pairing wireless communication with the transmitter using the pairing button, receiving RF for communication via WIFI, Bluetooth, LAN, etc., receiving a signal about the rising temperature in the protected area, disconnecting individual electrical circuits with rising temperature in the protected area from the electric current and transmitting such a signal to the signaling device.
The receiver includes an internal or external power supply, at least one monitoring LED for setting the pairing with the transmitter, and at least one LED for monitoring the transmitter arranged in the protected area to detect its error.
The transmitter and receiver of the system communicate wirelessly after pairing with each other. Activation of the system is triggered by increasing heat.
When the temperature rises in a protected area, such as an electrical outlet, a transmitter located in the protected area sends a signal to a receiver located at the location of the power source, such as an electrical distribution box, where a disconnector disconnects the electrical circuit where the transmitter is located. The said transmitter, comprising a carrier of a cooling medium with extinguishing effects, in which an opening/nozzle is formed due to the rising temperature, through which the cooling medium with extinguishing effects escapes into the space of the protected device, where it cools the rising temperature or extinguishes the resulting fire. System activation from 30° C. in a protected area.
Disconnecting the protected area from the power source prevents a electrical short circuit from occurring again.
The receiver shows digital or analogue signaling/initiation indication, i.e. the cooling medium with extinguishing effects is discharged from the cooling medium carrier with extinguishing effects, which is arranged in the transmitter, and due to the rising temperature this carrier breaks down, the cooling medium with extinguishing effects is discharged into a protected area, e.g. a socket, the transmitter sends a signal to the receiver, whereby the protected area, such as a socket or other electrical device, in which the damaged cooling medium carrier is located is accurately identified and easy replacement of the transmitter with the cooling medium carrier occurs.
The installation of an automatic communication system for local suppression of rising temperatures or extinguishing in electrical equipment connected to a power source is very simple.
The dimensions of the transmitter system are adapted to the size of the protected areas, which are for example sockets, switches, electrical appliances, extension cables, connectors, and other electrical equipment.
The automatic communication system for local suppression of rising temperature or fire extinguishing in electrical equipment connected to the power source is an active system.
The transmitter of the system also works passively—on its own, without a battery or external power supply, when the temperature in the protected device rises, the carrier of the cooling medium with extinguishing effects automatically breaks down and the medium enters the protected space in which the transmitter is arranged through the opening.
Automatic system communication for local suppression of rising temperature or extinguishing in electrical equipment connected to a power source is a safe product, does not endanger human health in terms of electrical energy or cooling medium with extinguishing effects. And the protected equipment is not damaged either.
