What is a voltage breakdown testing machine?
The voltage breakdown testing machine is a professional equipment used to test the insulation properties of materials. It is widely used in fields such as electricity, electronics, and materials science. It detects the breakdown voltage value of the material by applying high voltage to evaluate its dielectric strength and voltage resistance. This article will introduce in detail the principle, application scenarios, technical parameters and popular models of the voltage breakdown testing machine.
1. Working principle of voltage breakdown testing machine
The voltage breakdown testing machine gradually increases the voltage until the material under test breaks down, and records the voltage value at this time as the breakdown voltage. During the test, the equipment monitors current changes to ensure the safety and accuracy of the test. Here’s how it works at its core:
| steps | Description |
| 1. Sample preparation | Make the material to be tested into a specimen of standard size to ensure that the surface is clean and free of contamination. |
| 2. Voltage application | The voltage is increased at a constant rate or in steps until breakdown occurs. |
| 3. Data recording | Record the breakdown voltage value, current curve and environmental parameters (such as temperature, humidity). |
| 4. Result analysis | Determine whether the insulation performance of the material meets the standards through software or manually. |
2. Application fields of voltage breakdown testing machine
Voltage breakdown testing machines play an important role in multiple industries. The following are its main application scenarios:
| Industry | Specific applications |
