Transformer Oil Reservoir Automatic Pressure Deformation Test Platform
This test platform is equipped with high‑precision laser displacement sensors to measure real‑time deformation of transformer shell steel plates for bellows‑type oil‑conservators under positive‑pressure and vacuum‑pumping conditions. Pressure gauge readings and laser measurement data are synchronously transmitted to the controller. The measurement & control system couples pressure data and deformation data to derive the geometric quantitative correlation between them. Pressure‑time curves and deformation‑time curves are plotted in real‑time, so that the pressure and deformation status during the pressure leak test of the oil‑conservator can be visually presented on the software interface.
→ Automatically calculate the pressure fluctuation rate, the position of maximum deformation and its variation trend. Automatically generate PDF reports including key data, charts and pass‑fail judgement.
→ Positive‑pressure and pressure‑relief test: apply stepped air pressure of 0.03 MPa, 0.05 MPa, 0.1 MPa, 0.05 MPa, 0.03 MPa, meanwhile acquire deformation values at 19 measuring points. Perform point‑by‑point data coupling of air‑pressure values and deformation values to analyze and compare the correspondence between pressure and deformation.
→ 50 Pa vacuum threshold measurement: collect step‑by‑step pressure‑deformation corresponding data in the negative‑pressure vacuum‑pumping process. Hold pressure for a preset duration upon reaching the set value to measure stability performance. Conduct data detection on design‑specified deformation magnitude, pressure‑resistance duration and recovery performance when the vacuum pressure exceeds 50 Pa.
→ Pressure range: ‑0.05 MPa ~ +0.1 MPa; Sampling cycle: less than 100 ms
→ High‑rigidity ranging support stand combined with precision guide‑rail and slide‑block assembly; remote‑control adjustment for accurate positioning, fast and friction‑free travel.
→ PLC electrical control system, pneumatic pressure valve‑bank piping system, multi‑port valve plate, HRJ‑Test software for Transformer Oil‑Conservator Pressure‑Resistance Deformation Automatic Test Platform.
