Description

Title of the invention: Automatic communication system for local suppression of a temperature rise or fire extinguishing in electrical equipment connected to a power supply source Field of the invention

[0001] 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 an electrical distribution box, where the temperature may increase or a fire may start. Background of the invention

[0002] In lighting circuits, socket circuits or circuits with connected appliances such as electric ovens or cooking plates, undesirable thermal phenomena may occur, the negative effects of which may lead to a gradual loss of functionality or destruction of these devices and, in extreme cases, may even lead to a fire. These phenomena may be caused by various processes such as undesirable chemical reactions, electrical short circuits, overheating of the system, formation of an electric arc, combustion of working fluids, etc.

[0003] The known protections of the state of the art for socket or lighting circuits of electrical distribution boxes are 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 an extinguishing capability nor the ability to prevent temperature increases in control panels and their lighting, socket and other circuits. Summary of the invention

[0004] The present invention makes it possible to eliminate the above drawbacks and relates to an automatic communication system for local suppression of a temperature rise or extinguishing of a fire in electrical equipment connected to an electrical power source, said system comprising a transmitter arranged in at least one protected area (for example, a protected electrical device, such as electrical outlets, switches, electrical appliances, extension cords, connectors) connected to at least one electrical circuit of an electrical distribution box, the system further comprising a receiver arranged in the box of electrical distribution (i.e., at the location of the electrical power source).

[0005] The transmitter comprises a holder of a cooling medium having a fire extinguishing effect (or extinguishing effect), which is closed by a first terminal on one side, under which a control unit for communication with a battery is arranged, and on the other side the holder of the cooling medium having a fire extinguishing effect is closed by a second terminal.

[0006] The communication control unit includes a control light emitting diode (LED) for defining a pairing with the receiver.

[0007] The receiver comprises a pairing button for pairing a wireless communication with the transmitter, an internal or external power supply, at least one LED for setting the pairing with the transmitter, at least one LED for monitoring an error of the transmitter disposed in the protected area, and further comprises radio frequency (RF) receiving components for communication via a transmission network such as WIFI or Bluetooth® or wide area network (LAN).

[0008] According to a particular characteristic of the invention, the transmitter is powered externally.

[0009] According to a particular characteristic of the invention, the support of the cooling medium having an extinguishing effect is made of polymer materials, and is a low pressure device with a pressure of up to IMPa.

[0010] According to a particular feature of the invention, the communication control unit of the transmitter comprises a temperature or smoke sensor or a light spectrum sensor, an RF transmitter for wireless communication between the transmitter and the receiver via a transmission network such as WIFI or Bluetooth® or LAN, a pairing button for pairing the wireless communication of the transmitter with the receiver (arranged in the electrical distribution box in which a protected area, for example a socket, is connected to the electrical circuit), and the communication control unit comprises a control LED for defining the pairing of the transmitter with the receiver.

[0011] According to a particular characteristic of the invention, the receiver, which is arranged in a device with a power supply, such as an electrical distribution box, is compatible with a DIN rail ("Deutsches Institut fur Normung", or German Institute for Standardization).

[0012] The receiver allows pairing of wireless communication with the transmitter using the pairing button, RF (radio frequency) reception for communication via WIFI, Bluetooth®, LAN, etc., reception of a signal regarding the temperature rise in the protected area, disconnection, vis- with respect to electric current, of individual electrical circuits with a rise in temperature in the protected area, and transmission of such a signal to a signaling device.

[0013] The transmitter and receiver of the system can communicate wirelessly after pairing with each other.

[0014] Activation of the system is triggered by an increase in heat.

[0015] According to a particular characteristic of the invention, an electrical circuit, in which a protected area is located and in which a temperature rise or smoke or a light spectrum is detected by a sensor, is disconnected on the basis of a signal from a respective transmitter arranged in the protected area concerned sent via the receiver to a disconnector.

[0016] Advantageously, when the temperature increases 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 the disconnector disconnects the electrical circuit where the transmitter is located. Said transmitter comprises a holder of a cooling medium having extinguishing effects, in which an opening / nozzle is formed due to the temperature increase, through which the cooling medium having extinguishing effects escapes into the space of the protected device, where it cools the rising temperature or extinguishes the resulting fire.

[0017] According to a particular characteristic of the invention, the activation of the system takes place from 30°C in the protected zone.

[0018] Disconnecting the protected area from the power source prevents an electrical short circuit from occurring again.

[0019] According to a particular feature of the invention, the receiver shows a digital or analog signaling or system trigger indication, i.e. the cooling medium having an extinguishing effect is released (or discharged) from the cooling medium holder having an extinguishing effect, which is arranged in the transmitter arranged in a protected area, and that, due to the temperature rise, this holder is damaged (or decomposes) and the cooling medium having an extinguishing effect is released into the protected area, such as a socket, the transmitter sends a signal to the receiver. Thus, the protected area, such as a socket or other electrical device, in which the damaged cooling medium holder is located, can be precisely identified and an easy replacement of the transmitter with the cooling medium holder occurs.

[0020] The installation of an automatic communication system for local suppression of a temperature rise or fire extinguishing in electrical equipment connected to a power source is very simple.

[0021] According to a particular characteristic of the invention, the dimensions of the transmitter are adapted to the size of the protected areas, which are for example sockets, switches, electrical appliances, extension cables, connectors and other electrical equipment, in which it is arranged.

[0022] The automatic communication system for local suppression of a temperature rise or fire extinguishing in electrical equipment connected to the power source is an active system.

[0023] According to a particular feature of the invention, the transmitter further comprises a passive cooling or extinguishing function. Thus, the transmitter of the system also operates passively, by itself, without a battery or external power supply, when the temperature in the protected device increases, the support of the cooling medium having extinguishing effects breaks automatically and the medium enters the protected space in which the transmitter is located through the opening.

[0024] The automatic communication system for local suppression of a temperature rise or fire extinguishing in electrical equipment connected to a power source is a safe product, which does not endanger human health in terms of electrical energy or cooling medium having extinguishing effects. And the protected equipment is also not damaged. Brief description of the drawings
