Abstract

The invention discloses an experimental device for igniting combustibles through arc discharge. The experimental device comprises a power supply module, a load module, an arc striking module and a control platform. The input end of the power supply module is a 380V power distribution network, and the output end is connected with the arc striking module and the load module. The control platform obtains the voltage of the power supply module, the current of the power supply module, the temperature of the arc striking module and the pressure of the arc striking module in real time. The control platform adjusts the power of the load module and adjusts the motion state of the linear module. The experimental device has the functions that the environment atmosphere and the arc discharge energy can be regulated and controlled, and the combustible materials can be replaced, and the experimental device which is safe, reliable, good in repeatability and easy and convenient to operate is provided for research of the combustible materials ignited by the arc and test of the combustible materials ignited by the arc; the device can be used for studying the mechanism of igniting combustibles by arc discharge, studying the flame retardant property of the material under the action of the arc and the like.

Description

technical field [0001] The invention relates to the field of arc experimental devices, in particular to an experimental device for igniting combustibles by arc discharge. Background technique [0002] According to relevant statistics, electrical fires account for the largest proportion of all types of fire accidents, among which the damage caused by fault arc ignition is particularly prominent. The suddenness, concealment, randomness, high temperature and energy concentration of arc faults, in the power supply and distribution system, once the arc fault occurs and is not found in time, it may cause damage to the cable coating, electrical plastic casing, etc. Even the accidental ignition of combustibles near the faulty line can cause the spread of electrical fires. Therefore, an in-depth understanding of the dynamic parameters of the fault arc and the mechanism of the ignition of combustible solids by the fault arc is a necessary condition for optimizing the design of the po...
