High-voltage electrical equipment electrical porcelain importance and performance in the earthquake

Porcelain columnar sulfur hexafluoride circuit breaker for the study, carried out shaking table test and finite element analysis , the establishment of an effective system of electrical porcelain electrical equipment ( including shock absorbers, wire ) finite element model and the corresponding computational analysis method to study the seismic performance of high voltage electrical equipment and conductors for electrical equipment shock absorbers and seismic performance.  air circuit breaker  and obtained findings : porcelain -type high voltage electrical equipment and its importance in the earthquake performance. Damage data indicate that the high-voltage electrical equipment electrical porcelain damage is caused by high voltage grid system to destroy the key point, and the destruction of such  mcb circuit breaker  due to equipment damage caused by brittle ceramic column section . Accordingly, the seismic performance of such equipment in the past  Voltage stabilizer  on research ceramic column . According porcelain high-voltage electrical equipment as well as the structural features of the device at run-time state shows that the factors that affect the seismic performance of the device include: ceramic column , the connection between the ceramic column flange, equipment support , shock absorption and isolation device equipment , the wires between devices . This departure from these factors , summarizes the current research on these factors and problems , and identifies research content .
