Background
With the development of the ultra-high voltage direct current transmission technology, the direct current transmission plays a great role in the formation of a power grid, particularly in 'west-east transmission'. The southwest area as a power source is in an earthquake-prone area, and the safety of related power equipment under the action of an earthquake needs to be concerned. The converter valve, the insulator, the lightning arrester and the pipe bus are important equipment of an ultrahigh-voltage and ultrahigh-voltage direct-current transmission system, the system is generally called as a valve hall system, and the integral anti-seismic performance of the valve hall system under the action of an earthquake is a key for ensuring the safe and reliable operation of the transmission system.
At present, the valve hall system equipment is connected by adopting a pipe bus, a flexible lead and a flexible hinge, and the common connection mode can only meet the seismic requirement of relatively low seismic intensity.
