External Insulation Design of Converter Stations for Xiangjiaba - Shanghai ± 800 kV UHVDC Project
-External insulation is one of the critical aspects in the HVDC equipments and converter station design. Especially for UHVDC converter stations, the long creepage and clearance required has significant impact on the equipment and station design. The external insulation design of DC yard, valve hall, and for converter valves is presented. It is the intention of this report to review and summari...
متن کاملEffects of aging on the structural, mechanical, and thermal properties of the silicone rubber current transformer insulation bushing for a 500 kV substation
In order to analyze the cracking and aging reason of the silicone rubber current transformer (CT) insulation bushing used for 8 years from a 500 kV alternating current substation, characteristics including Fourier transform infrared (FTIR) spectroscopy, mechanical properties analysis, hardness, and thermo gravimetric analysis have been carried out. The FTIR results indicated that the external s...
متن کاملElectric and Magnetic Field Computation of 35 Kv Voltage Level of Transformer Substation 35/10 Kv Using the Cdegs Software
Paper presents electric and magnetic field computation of 35 kV voltage level of transformer substation 35/10 kV using CDEGS software. Based on well known theoretical considerations of electric and magnetic fields, a realistic simulation model of transformer station 35/10 kV was develop. All calculations are made for horizontal plane with height of 1,5 m above the soil changing coordinates alon...

متن کاملAssessment of Electric Field Distribution Inside 500/220 kV Open Distribution Substations during Working Conditions
Received Mar 2, 2014 Revised Jul 10, 2014 Accepted Jul 23, 2014 The high level electric field intensity produced by high voltage (HV) equipments inside 500/220 kV substations is harmful for the human (staff) health. Therefore the minimum health and safety requirements regarding the exposure of workers to the risk arising from electric fields produced inside these substations is still considered...
