Film capacitor common pressure tester composition

The pressure testers currently available on the market mainly provide voltage regulator power supply, analog circuit detection, and a new type of withstand voltage tester that uses all-electronic program control technology and power electronics technology. The current new type of withstand voltage test instruments are mainly divided into two types: one is to use a single-chip microcomputer as a monitoring center, digital waveform synthesis technology and a linear power amplifier as test power supplies; the other is to use a single-chip microcomputer as a monitoring center, and the test power supply uses SPWM ( Sinusoidal Pulse Width Modulation) Pulse Generator and IGBT (Insulated Gate Bipolar Transistor) Pulse Power Amplifier.

These new withstand voltage testers have small distortion of output waveform, wide output voltage adjustment range, high control precision, stable output voltage in the power range, and are not affected by load changes. The output power of test power supply can generally reach 500W, and super power output. When the instrument can be automatically protected, the output voltage is set to be carried out without voltage output, and the safety is good. It is easy to realize the detection of potential hidden dangers such as arc, creepage, flashover and other insulation properties of the test article, and can accurately detect Whether there is a hidden danger in the film capacitor.

The voltage output mode can meet various standard requirements through software, such as step-up boost, timing boost, fixed-speed boost, etc. It can perform breakdown point analysis, fast breakdown protection, and leakage current display resolution up to Naan. Class, suitable for high-standard component testing of film capacitors.
