FIELD: fire-prevention facilities.SUBSTANCE: invention relates to non-contact methods of protection of an object from fire hazard and/or fire extinguishing by means of generated electric field. The method of protection of an object from fire hazard with automated stationary fire extinguishing system, which comprises a control unit, fire detection means and unit of generating the working electric field and two oppositely charged electrodes. The system is connected to a power source, brought into a state of expectation of the fire risk and maintain constant monitoring of security. In recording the combustion in automatic mode, the information is received about the location and extent of combustion, after which the electrodes of the corresponding unit which is located at the place of combustion, high voltage is applied. The working electric field is generated and the flame is affected with it until his complete disappearance. The process is conducted using a system configured with the ability to control high voltage which is applied to the electrodes. The opposite electrodes are arranged in two opposite or in two adjacent to each other planes of areas of the protected object. The shape of the electrodes and the technological gap h between them is determined on the basis of the conditions for obtaining the electromagnetic field screen, which affects simultaneously on the entire amount of the flame. The amount of the applied high voltage is selected from the range of values that is defined for specifically established value of interelectrode technological gap h, which eliminates the possibility of property damage both from the fire itself and from the consequences of its suppression.EFFECT: improving the effectiveness of protection.2 cl, 3 dwg |
