Description

Technical Field

[0001] The utility model relates to the technical field of film boiling water tests, in particular to a film boiling water test device. Background Art

[0002] In the quality inspection of the insulating materials of composite insulators, the boiling water method for testing their hardness is one of the common detection methods and an effective means to ensure the safe operation of composite insulators. According to the requirements of Clause 6.1 of DL / T 376-2019 "General Technical Conditions for Insulating Materials for Polymer Insulator Skirts and Jackets", a boiling water test needs to be carried out on the film. According to our test requirements, the boiling water test device needs to simultaneously take into account the core rod water diffusion test for 96 hours and the film hardness change test for 42 hours. The core rod has a large diameter and a long test time, which puts higher requirements on the container capacity and sealing performance of the boiling water test. Conventional boiling water test containers are difficult to meet the test requirements. In daily tests, due to the defects of the test equipment, situations such as water shortage and overheating are likely to occur during the test, and the operators cannot supervise in time, resulting in low safety performance of the test. In addition, the materials placed in the test equipment are also prone to uneven heating, resulting in inaccurate test results. Content of the Utility Model
