Abstract

A cable flame-retardant combustion test device based on automatic control of a computer includes an electrical control cabinet, a power source, a test sample bracket, a burner, a fuel gas regulating valve, an air regulating valve, a voltage regulator, a voltage regulation indicator gauge, a current regulator, a current regulation indicator gauge, a phase connection/disconnection display device, a fuel gas pressure gauge, an air pressure gage, a fuel gas flow meter and an air flow meter, and is characterized by further including the computer installed with control software; the fuel gas flow meter, the air flow meter, the fuel gas pressure gauge, the air pressure gauge, the voltage regulation indicator gauge, the current regulation indicator gauge and the phase connection/disconnection display device are all provided with communication interfaces and in communication connection with the computer; both the fuel gas regulating valve and the air regulating valve are electric control valves and act as per control signals output by the computer respectively; and the voltage regulator and the current regulator act as per control signals output by the computer respectively. Through adopting the cable flame-retardant combustion test device, the testing process is automatically and precisely controlled by the computer, the testing result is more accurate and reliable, the efficiency is high, and the original testing data can be stored.

Description

technical field [0001] The invention relates to a cable burning test device, in particular to a cable flame retardant burning test device. Background technique [0002] At present, the equipment for carrying out the cable flame retardant combustion test includes the test sample rack and burner arranged in the airtight room, and also includes the electrical control cabinet arranged in the airtight room. [0003] When testing the fire resistance of the cable, the cable sample is installed on the test sample rack, a certain current is passed through the cable, a certain voltage is applied to both ends of the cable, and then the burner is ignited to burn the cable. The corresponding phase indicator light on the cabinet will go out. [0004] However, the existing test device can only manually adjust the voltage and current, and manually adjust the gas and air, which is time-consuming and laborious, and is affected by human factors, the adjustment is not easy to control, and it i...
