BAIJIAN - Third party testing organization
Test items: appearance inspection、 tightness、 looseness、 rust and fracture、 smoothness、 no bubbles、 wrinkles、 cracks、 insulation layer detachment、 serious mechanical or electrical burns、 adhesive opening、 power frequency withstand voltage test、 DC withstand voltage test、 etc. Detection scope: High voltage brake rod、 insulation operating rod、 insulation rod、 high voltage operating rod、 multi-purpose Lingke rod、 10KV insulation operating rod、 35KV insulation operating rod、 110KV insulation operating rod、 220KV insulation operating rod、 330KV insulation operating rod、 500KV insulation operating rod、 etc. Test items: insulation、 bending strength、 compressive strength、 fracture strength、 bonding strength、 sealing、 corrosion resistance、 rigidity、 toughness、 etc. Reference standard: GB/T 38877-2020 Electrical Steel Strip (Sheet) Insulation Coatings GB/T 2011.15-2020 Thermal Evaluation Regulations for Electrical Insulation Systems - Part 5: Applications with a Design Life of 5000h and Below - DB53/T 496-2013 Technical Requirements for Insulation Reinforcements for High Voltage Switchgear in Plateau Areas - DL/T 1530-2016 High Voltage Insulated Fiber Optic Columns GB/T 9330-2020 Plastic Insulated Control Cables GB/T 28541-2012 ± 800kV High Voltage DC Converter Station Equipment - Insulation Coordination GB/T 37659-2019 Insulation Film for Laminated Bus Bars GB/T 37556-2019 10kV Live Working Industrial insulated bucket trucks GB/T 31838.4-2019 Solid insulation materials - Dielectric and resistance characteristics - Part 4: Resistance characteristics (DC method) - Insulation resistance GB/T 24835-2018 1100kV gas insulated metal enclosed switchgear - Operation and maintenance regulations - Test method: After completing the test wiring、 place the test object on the test stand、 turn on the power switch of the tester、 and connect the test power. Enter the sample parameter setting menu、 set the sample number and test voltage. This device then enters the system settings menu to set and measure the coil voltage. After setting the parameters、 the pilot control enters the fully automatic voltage withstand test item、 sets the test time、 and does not need to set the breaking current. Press the confirm button to enter the test state、 turn on the "main power input switch" on the tester panel、 press the confirm button again to start the test、 and the tester will automatically start boosting at the speed required by the national standard. After reaching the set voltage value、 maintain the voltage and start timing. During the test、 the leakage current will not be displayed. When the timer expires、 the tester automatically depressurizes. If there is a test item worn、 the tester will automatically cut off the test power and stop the test
