The wire and cable horizontal combustion test device comprises a combustion furnace, an exhaust transition section is arranged at the other end of the combustion furnace, an exhaust pipeline is arranged on one side of the exhaust transition section, a smoke density measuring mechanism is arranged on the exhaust pipeline, a waste gas pipe is arranged on one side of the exhaust pipeline, a smoke exhaust fan is arranged on one side of the waste gas pipe, and a waste gas treatment mechanism is arranged on one side of the smoke exhaust fan. PLC programming, a human-computer interface and computer control are adopted, test data can be checked in real time in the control test process, automatic data acquisition and processing, data storage and determination result output can be achieved, the whole test process is controlled through a computer, the test time, the test frequency, the delayed combustion time and the like can be set and recorded in the computer, automatic detection control is achieved, and detection work is automatically completed.

Description

technical field [0001] The invention relates to the field of cable combustion simulation analysis, in particular to a horizontal combustion test device for electric wires and cables and a test method thereof. Background technique [0002] With the rapid development of today's society, cables are more and more widely used in various industries. However, the application of cables has brought great benefits to the society and at the same time caused many fire safety hazards. Once a fire breaks out, it will not only increase the intensity of the fire but also easily spread along the laying direction of the cables. In addition, due to the Most of the materials are polymers, which produce a large amount of smoke after burning, most of which are toxic and corrosive gases that are harmful to the human body, which not only poses a great threat to people in the fire scene, but also hinders the rescue work of firefighters. [0003] The prior art has the following deficiencies: at pres...
