Core technology and innovation
1. Ultra-low power supply capacity: 315kVA power supply capacity can meet the short-circuit test capacity of 14MVA;
2. The equipment satisfies the short-circuit capacity test of the transformer and the no-load and temperature rise test of the distribution transformer at the same time;
3. It has the ability to compare the characteristic parameters before and after the short-circuit withstand test of the transformer, and directly judge whether the short-circuit withstand ability of the transformer is qualified or not through the comparison result;
4. Ultra-fast and large-capacity phase-selective AC electronic switch, response time is less than 5us, no mechanical oscillation; applied to short-circuit on the low-voltage side of the transformer, which can meet verification
The short-circuit performance of the sample under different voltage phases;
5. Short-circuit withstand test and characteristic parameter test comparison test, only one-time wiring is required, and the entire test flow can be controlled centrally through the control software platform
The comparison and judgment of the process and the results make the most difficult type test of distribution transformers simple and easy to operate.
