The results show that the critical explosion suppression length increases first and then decreases with the increase of methane concentration. When the methane concentration is 11%, the critical explosion suppression length is the biggest, which is 1.6 m. With the increase of the length of the suppression section, the overpressure curve first changes from a high-pressure single peak to a double peak and finally to a low-pressure single peak. After ignition, the nitrogen in the suppression section moves to the right with the flame under the driving effect of thermal expansion of combustion products. When the flame propagates near the suppression section, the nitrogen section stops moving right. Then, under the disturbance of the explosion wave, the suppression section is stretched. When the length of the suppression section is less than the critical explosion suppression length, the flame passes through the suppression section to ignite the combustible mixture, causing a secondary explosion. If the suppression length is greater than the critical explosion suppression length, the flame will gradually extinguish in the suppression section.

However, research on the ignition of energized wires by arcs was not clarified. In this study, the standardized cone heater was used to simulate high-temperature conditions in order to investigate the occurrence of short circuits in energized cables within a high-temperature environment, as well as the characteristics and correlations of the combustion. The intensity of thermal exposure was accurately controlled through adjustments to the heat flux emitted by the cone heater. The short circuits in thermally exposed cables could be classified as a single arc or multiple arcs based on the fluctuations observed in voltage and current upon the occurrence of an arc. The results indicated that the minimum heat flux leading to a short circuit was 22 kW/m<sup>2</sup>. A short-circuit arc became inevitable once the heat flux surpassed 25 kW/m<sup>2</sup>. Notably, when the heat flux exceeded 26 kW/m<sup>2</sup>, the probability of multiple short circuits within the conductor escalated significantly, reaching 83.7%. Compared to a single arc, multiple arcs exhibited a shorter initial occurrence time, a longer duration, and a higher probability of igniting cable insulation. The spread distance of combustion due to multiple arcs was primarily concentrated within the range of 23–28 cm.
