At the invitation of the customer, the Wuhan UHV after-sales service team went to the customer's project site to conduct training and guidance on the UHV-1536kV/270kV variable frequency series resonant withstand voltage test device.
After contacting the customer, Wuhan UHV technicians arrived smoothly at the required time. After the technical personnel communicated with the person in charge of the site, it was learned that the customer used the UHV-1536kV/270kV variable frequency series resonance withstands voltage test device to carry out the AC withstand voltage test on a 110kV cable with a length of 1.4 kilometers and a cross-section of 1000mm², so the combination of two reactors in parallel was used for the withstand voltage test.
First, Wuhan UHV technicians arrived at the customer test site to assemble and provide on-site wiring guidance for the UHV-1536kV/270kV variable frequency series resonant withstand voltage test device. After the equipment is assembled and the wiring is correct, the technician gave a detailed and detailed explanation of the wiring method, use method and precautions of the equipment. Before starting the test, it is necessary to confirm the on-site safety measures, measure the insulation of the test product, and conduct an AC withstand voltage test on the cable and GIS together at 64kV according to the customer's requirements.
After the completion of phase A test, the test sample is discharged and the two phases B and C are replaced. The test is operated by the customer's on-site personnel, and the technical personnel provide guidance. For the remaining two phases, the field personnel used the automatic test and manual test functions of the instrument. When the pressure down was stopped, the on-site personnel tested the emergency stop button on the instrument panel, and everything worked normally. In the process of operation, the on-site personnel were very satisfied with the automatic test function of the Wuhan UHV instrument and praised it!
After several hours of waiting, the remaining two-phase withstand voltage test was successfully completed. Through the guidance of Wuhan UHV technicians, the on-site personnel personally started the test operation, and soon mastered the use of the instrument and precautions. So far, the after-sales service journey has come to a successful conclusion!
Over the years, the Wuhan UHV after-sales team has been enthusiastic to provide customers with warm service to solve all kinds of problems and ensure that Wuhan UHV equipment is efficiently used in the customer base. In the future, Wuhan UHV will continue to serve every customer with a professional and dedicated attitude and escort customers' on-site tests!
