In train travelling process, always wish that pantograph can be remained with contact line and contact.Increase the lift of pantograph
Lift and mitigation pantograph quality can also improve current carrying quality.But it is restricted to increase pantograph lifting force, increase lifting force
Although can allow pantograph preferably with contacting linear contact lay, the abrasion of pantograph pan and contact line can be accelerated simultaneously, easily
Increase the metal fatigue of contact line, shorten its life-span.Therefore, pantograph lifting force is needed to consider, and Rational choice could be obtained
To optimum efficiency.
Contact net static parameter is the basic guarantee of good bow net dynamic property, and bow net dynamic property is that fortune is listed in limitation again
One of principal element of scanning frequency degree.In construction, operation, maintenance process, the possible off-design ginseng of contact net static parameter causes
Contact line nature static changes, or even hard spot occurs, influences bow net dynamic effects bow net dynamic operation performance.
