IIComplete set of equipment for frequency conversion series resonance testBasic principle:
The resonant withstand voltage test is a new method of high voltage testing that uses the inductance of a reactor and the capacitance of the test object to form an LC series circuit, adjusts the voltage frequency output of a variable frequency power supply, achieves series parallel resonance, and obtains high voltage on the test object. It has received high praise and has been widely used at home and abroad.
IIIComplete set of equipment for frequency conversion series resonance testFeatures:
1. It has a large output capacity, high output voltage, and the ability to freely combine reactors for AC withstand voltage testing of different samples.
2. It has small size, light weight, and is particularly convenient for field experiments.
3. It has good protection functions, such as overvoltage protection, overcurrent protection, time protection, flashover protection, overheating protection, module protection, etc.
4. It is easy to operate and has two modes: manual and automatic.
5. Using a large screen to make the test data clear at a glance and print the test results.
6. There is no risk of overvoltage after sample breakdown, and the damage to the sample is relatively small.
7. The power supply capacity required for the frequency conversion series resonance test device is small, only a fraction of the power supply capacity required for the power frequency transformer test, solving the problem of difficulty in finding on-site power supply.
