Problems solved by technology

[0002] At present, after the heating tube is processed, it is necessary to conduct a dry-burning fuse test. The existing test equipment is mostly split assembly equipment. The equipment uses a contact voltage regulator, a fuse tester and a set of detection aids. The reaction time of the dry-burning fuse is 50±20 seconds. After the fuse is blown, the withstand voltage and leakage ...

Abstract

The invention relates to an experimental test device for dry burning and melting of a heating tube, which comprises a frame; a closed flame-retardant operation box is arranged on the left side of theframe, a test system on the right side; the test system is connected with an electrode clamp located in the flame-retardant operation box, and a test instrument and a programmable power supply locatedon the lower side of the frame; the test instrument is used for testing the power, the current and the resistance; and a thermal printer, which is connected with the test system for printing test data, is installed on the frame. The experimental test device for dry burning and melting of a heating tube in the invention can avoid a direct exposure test, has the advantages of high test safety, stable test voltage, automatic acquisition and printing of the test data, and greatly facilitates the test for dry burning and melting of the heating tube.

Description

technical field [0001] The invention relates to the technical field of heating tube testing, in particular to a heating tube dry-burning fusing experiment testing equipment. Background technique [0002] At present, after the heating tube is processed, it is necessary to conduct a dry-burning fuse test. The existing test equipment is mostly split assembly equipment. The equipment uses a contact voltage regulator, a fuse tester and a set of detection aids. The reaction time of the dry-burning fuse is 50±20 seconds. After the fuse is blown, the withstand voltage and leakage current meet the requirements. Because the heating tube is exposed during the entire test process, it has certain safety hazards; the unstable voltage adjustment of the voltage regulator during the test will affect the test. As a result, the test data needs to be collected manually, and the operation is cumbersome, which is not conducive to the dry-burning fusing test of the heating tube. Contents of the ...
