A connection device, a control box component, and a fracturing apparatus are provided. The connection device includes: a fixation rack, configured to be fixedly connected with a mounting base; a box connection mechanism, configured to be connected with the control box, and drive the control box to move at least from a first position to a second position relative to the fixation rack. In a case that the control box is located at the first position, the control box is located at a side of the transmission component and a distance between the control box and the transmission component is less than a predetermined distance, and during the control box being moved from the first position to the second position, the control box is away from the transmission component to form an operation space for the transmission component at the first position.

Systems and methods include a computer-implemented method for providing a predictive pressure protection system. Flare sources, performance limits, and relationships between control valves and relief valves are established. A flare simulator is generated using piping isometric drawings. An emergency event is monitored, and information for the emergency event is filtered based on a control valve limit breach. Event start and finish time periods are divided into cases representing smaller time frames. Source max loads are determined for each case, and each case is run through the flare simulator. Flare/relief valve performance indicators are determined based on the source max loads after running each case.

A method for use with an underground network that includes a plurality of locations. The method includes receiving sensor data from at least one sensor located at a first of the plurality of locations and determining the sensor data indicates that a fire is in progress. The method includes identifying one or more of the locations as one or more potential combustion locations and assigning an estimate of a probability to each of the potential combustion location(s). The estimate estimates a likelihood that the potential combustion location is an actual combustion source. The method may include displaying the estimate of the probability assigned to each of the one or more potential combustion locations.
