Abstract

The invention discloses a linear fire source spreading device which comprises a linear fire spreading simulation system, a smoke spreading simulation system, a smoke and fire source spreading controlsystem and a fire source power measuring system. The linear fire spreading simulation system simulates a linear fire source, the smoke spreading simulation system simulates smoke spreading and is ledto the linear fire source, the smoke and fire source spreading control system can control the fire source and smoke spreading state, and the fire source power measuring system can measure the power ofthe fire source. The device has the advantages that spreading of the linear fire source is simulated and includes transverse spreading and longitudinal spreading of the fire source, wherein the longitudinal spreading mode further comprises one-side spreading and two-side spreading. Over-firing region fire source attenuation and extinguishing spreading can be achieved, the flame spreading direction and speed can be remotely and accurately controlled through a computer, synchronous spreading of smoke and flames can be achieved, and meanwhile the smoke flow rate and concentration can be precisely measured.

Description

technical field [0001] The invention relates to the field of electrical fires, in particular to a linear fire spreading device. Background technique [0002] Cable channels, including cable trenches, cable tunnels and electrical shafts, are the main laying places for long-distance power transmission lines. When electrical faults occur on cables due to insulation aging and other reasons, fires may occur. And the smoke spreads quickly inside it, which may bring a major threat to the power system in a short period of time. Therefore, the research on the fire mechanism and prevention technology of the cable channel is of great significance. The simulation test is an important means of fire research, and the accuracy of the simulation test has a great relationship with the simulated fire source. In the fire test research, the ignition source is the most widely used fire source. However, in the electric place fire caused by the cable, the point-type simulated fire source is not ...
