Abstract: A method, an apparatus, a computer readable media, and a computer program product for detecting a gas leak of a gas tank. The method includes obtaining a gas pressure within the gas tank and a temperature of a tank body of the gas tank; determining an internal average temperature of the gas tank based on the gas pressure; determining a temperature rise of the tank body relative to an ambient temperature; and determining at least one additional characteristic quantity associated with the temperature rise of the tank body. A gas leak of the gas tank can be detected by using the internal average temperature of the gas tank, the temperature rise of the tank body, and the at least one additional characteristic quantity to obtain a predicted relationship between the internal average temperature of the gas tank and the temperature rise of the tank body.

Abstract: Methods, apparatuses, systems, computer readable media, and a computer product for detecting a gas leak of a gas tank. In a method, at least one inside temperature is determined for the gas tank based on a plurality of outside temperatures that are collected outside the gas tank, the at least one inside temperature being estimated for at least one inside position within the gas tank during an operation of the gas tank. A gas pressure within the gas tank under a standard temperature is obtained based on the at least one inside temperature. The gas leak of the gas tank is detected based on the gas pressure.

Abstract: A method and an apparatus for training a model for predicting a temperature rise of a heating element in a switchgear. The method includes obtaining a model for predicting the temperature rise. The method also includes obtaining n+1 sets of physical quantities in relation to the heating element, each set of physical quantities being collected at a corresponding one of n+1 time points spaced apart from each other by a time step in a normal operation state of the heating element, each set of physical quantities comprising a current and an actual temperature of the heating element and an ambient temperature. The method includes converting the actual temperature in each set of physical quantities into an actual temperature rise based on the corresponding ambient temperature; and training the model with the current, the actual temperature rise and the ambient temperature to determine the several parameters.
