Description

With the rapid development of electrical technology, the voltage grade and performance requirements of various electrical equipment are increasingly different, which puts forward higher challenges to the functionality and adaptability of high pressure test equipment.

[0003] At present, there are various high pressure test equipment on the market, and some of the structures expose many defects in actual application. The existing switching test loop mode is extremely cumbersome when facing different pressure range of the measured piece. When it is necessary to switch from one pressure tester to another, the staff must manually replug and connect a large number of complex lines, which not only consumes time and effort in the operation process, but also easily leads to line connection error due to improper operation. Moreover, frequent plugging operation will aggravate the wear of line interface, leading to increased contact resistance, causing heating and virtual connection problems, which seriously affect the accuracy and stability of test results.

[0004] In addition, the existing test structure usually lacks effective fixation and protection mechanism for test loop switching. During the test process, due to equipment vibration or external interference, the connection part after switching may be loose, causing test interruption or data anomaly, not only reducing the test efficiency, but also possibly leading to misjudgment of product quality due to error data, causing great loss to production and research and development.

[0005] Therefore, a high pressure test switch is proposed. UTILITY MODEL CONTENT
