Problems solved by technology

[0003] In the traditional electric strength test, only the electric strength of two independent conductive parts can be tested each time. Taking the electric strength test of a 40-core cable as an example, a total of 40+39+ 38+37+...+2+1=820 times of detection, each power-on detection time is 1 minute, without counting the manual insertion process time, it still takes nearly 14 hours to complete the detection, time-consuming and laborious, serious Affect the production schedule
In addition, during the detection process, the handle needs to be shaken manually, which is inefficient and prone to electric shock hazards

Abstract

A general-purpose electric strength detection device, including a relay group, one input end of the relay group is connected with a transformer that can convert the mains AC220V and output a standard detection voltage of AC500V; the other input end of the relay group It is connected with a programmable controller PLC that can control the electrical signal of the relay group; the output terminal of the relay group is connected to the component to be detected through a transfer wire; it also includes a AC220V that can convert the mains power and output DC24V voltage to the programmable controller The PLC provides a stabilized power supply of the working voltage; the invention has obvious effects on improving the reliability of electric strength detection, improving work efficiency, reducing the frequency of quality problems, and eliminating potential safety hazards.

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...
