Amount, g are gravity proportionality coefficient, and e is constant.
Since the conducting ring 234 is equipped with the interconnecting piece, the 234 inner surface tilt angle of conducting ring and institute
State that interconnecting piece outer surface tilt angle is identical, the setting of the 234 inner surface tilt angle of conducting ring influences the conducting ring 234
The size of frictional force between the interconnecting piece, frictional force need to guarantee described lead between the conducting ring 234 and the interconnecting piece
Electric ring 234 and the interconnecting piece are in the case where the controller applies the connection status after certain pressure, the conducting ring 234 and described
Frictional force between interconnecting piece is less than the frictional force between the interconnecting piece internal component, and the conducting ring 234 and described
Frictional force between interconnecting piece, which can drive the connecting rod to rotate, causes the arrester to stretch out out of blade；Therefore when described
When the axial compressive force that controller applies is bigger, frictional force is increased with it between the conducting ring 234 and the interconnecting piece, need to be by institute
The tilt angle for stating the setting of 234 inner surface of conducting ring reduces, and adjusts the frictional force between the conducting ring 234 and the interconnecting piece
Meet the working condition of the generating equipment thunderstorm electricity protective device.
