Description

AUTOMATIC COMMUNICATION SYSTEM FOR LOCAL SUPPRESSION OF TEMPERATURE RISE OR FIRE EXTINGUISHING IN ELECTRICAL EQUIPMENT CONNECTED TO A POWER SOURCE Field of the Invention The invention relates to the protection of electrical equipment, such as sockets, switches, electrical appliances, extension cords, plug connections and other electrical equipment, which is connected to equipment connected to a source of electrical power, for example an electrical distribution box, where the temperature may rise or a fire may occur. Prior art of the invention In lighting circuits, contact circuits or circuits with connected appliances, such as electric ovens or hobs, undesirable thermal phenomena can occur, the negative effects of which can lead to a gradual loss of functionality or to the destruction of these devices, and in extreme cases can even lead 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. The prior art protections for electrical switchboards or lighting circuits are so-called arc flash protection devices, which have the ability to mitigate the effects of an inadvertent arc by disconnecting the power source. However, arc flash protection devices do not have the ability to extinguish a fire or prevent the temperature from rising in the switchboards and their lighting, socket and other circuits. Technical essence of the invention The above disadvantages are eliminated by an automatic communication system for local suppression of temperature rise or fire extinguishing in electrical equipment connected to an electrical power source, the essence of which is that it consists of a transmitter located in at least one protected electrical device, such as electrical sockets, switches, electrical appliances, extension cords, plug connections connected to electrical circuits, and a receiver located at the location of the electrical power source, for example inside an electrical distribution box. Wherein the transmitter includes a carrier of a cooling medium with a fire extinguishing effect, which is closed by a first terminal on one side, under which a communication control module with a battery is located, and on the other side the carrier of the cooling medium with a fire extinguishing effect is closed by a second terminal. The transmitter is also externally powered. The cooling medium carrier is a fire extinguishing effect made of polymer materials, it is a low pressure device up to 1MPa. The transmitter communication control module includes a temperature or smoke sensor, or a light spectrum sensor, a radio frequency (RF) transmitter for communication, for example WIFI, Bluetooth, LAN and others, a pairing button for connecting the wireless communication of the transmitter is the receiver, located in an electrical distribution box in which there is a protected area, for example a contact that is connected in the electrical circuit, and the communication control module includes a control LED (LED) for setting the pairing of the transmitter with the receiver. Wherein the receiver, which is located in a powered device, such as an electrical distribution box, is DIN rail compatible. The receiver allows pairing of wireless communication with the transmitter, by using the pairing button, receiving RF for communication, via WIFI, Bluetooth, LAN, etc., receiving a signal about the increase in temperature in the protected area, disconnecting individual electrical circuits from the power supply when the temperature in the protected area increases, 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 up the pairing with the transmitter, and at least one monitoring LED for the transmitter located in the protected area for detecting its error. The system's transmitter and receiver communicate wirelessly after pairing with each other. The system is activated when the heat increases. 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 power source, such as an electrical distribution box, whereby a circuit breaker disconnects the electrical circuit where the transmitter is located. In said transmitter, comprising a carrier of a cooling medium with fire extinguishing effects, in which an opening / nozzle is formed due to the rising temperature, through which the cooling medium with fire extinguishing effects is enters the space of the protected device, where it cools the rising temperature or extinguishes the fire that has occurred. System activation at 30°C in the protected area. Disconnecting the protected area from the power source prevents a repeat occurrence of an electrical short circuit. The receiver displays a digital or analog indication of signaling / initiation, i.e. the cooling medium with fire extinguishing effects is released from the cooling medium carrier with fire extinguishing effects, which is located inside the transmitter, and as a result of the temperature increase this carrier is damaged, the cooling medium with fire extinguishing effects is released into a protected area, for example a contact, the transmitter sends a signal to the receiver, whereby the protected area, such as a contact, or another electrical device in which the damaged cooling medium carrier is located, is accurately identified and the transmitter with the cooling medium carrier is easily replaced. Installing an automatic communication system for local suppression of temperature rise or fire extinguishing in electrical equipment connected to a power source is very simple. The dimensions of the transmission system are adapted to the size of the protected areas, which are for example sockets, switches, electrical appliances, extension cords, plug connections and other electrical equipment. The automatic communication system for local suppression of temperature rise or fire extinguishing in electrical equipment connected to a power source is an active system. The system transmitter also works passively - independently, without a battery or external power source. When the temperature in the protected device rises, the carrier of the cooling medium with fire-extinguishing effects is automatically damaged and the medium enters the protected space in which the transmitter is located through the opening.
