The invention provides a method and system for obtaining the highest surface temperature value of an explosion-proof device. A resistor is installed on the inner surface of the rear shell of the explosion-proof box for testing, and a temperature sensor is installed on the temperature test point on the outer surface of the explosion-proof box. The power consumption value of the resistor is obtained under the value, and the maximum temperature value is obtained according to the temperature sensor, and the maximum temperature rise value is obtained after subtracting the ambient temperature. The curve fitting of multiple groups of power consumption values and the maximum temperature rise value is obtained to obtain the fitting formula. When using It is required to bring the total power consumption value of the built-in components into the fitting formula to obtain the maximum surface temperature rise value of the flameproof device, combined with the ambient temperature to be used to obtain the maximum surface temperature value of the flameproof device, so as to obtain the group of the flameproof device , Different explosion-proof cabinets make the groups of explosion-proof devices different. Select the appropriate explosion-proof cabinet according to the needs to achieve the purpose of quickly selecting the appropriate explosion-proof cabinet.
Description
technical field [0001] The invention relates to the technical field of explosion-proof equipment, in particular to a method and system for obtaining the maximum surface temperature value of an explosion-proof device. Background technique [0002] Potentially explosive atmosphere. (such as: flammable gas, dust environment, oil refinery, petrochemical plant, gas station, gas filling station, etc.), the mixture of gas, steam or mist combustible substances and air under the atmospheric conditions of explosive gas environment, in the mixture Once ignited, combustion will spread throughout the environment of the unburned mixture. (Such as: CH4, C2H2, C2H4, NH3, CO, C2H5OH and other explosion-proof electrical equipment). Explosion-proof equipment definition: Electrical equipment that will not cause the surrounding explosive atmosphere to ignite under specified conditions. Maximum surface temperature: the maximum temperature reached by any part of the electrical equipment that ma...
