Description

technical field

[0001] The invention belongs to the technical field of electronic measurement, and in particular relates to a universal electric strength detection device. Background technique

[0002] Dielectric strength test mainly refers to the test of the electric strength between the conductive parts of electrical components such as cables and angle limiters that are not connected to each other. By applying a test voltage of 500V AC between the terminal pair shell and the terminals that are not connected to each other, observe whether there is breakdown, arc or corona in each independent conductive part of the component. The detection of electric strength is to ensure that the electronic An important part of the safety performance of the electrical circuit of the product.

[0003] In the traditional electric strength test, only the electric strength of two independent conductive parts can be tested at a time. Taking the electric strength test of a 40-core cable as an e...
