In：1st, product has inborn NTC (negative temperature coefficient) defect, easily produces blast and scaling loss miscellaneous equipment；2nd, existing market
Product, because being to carry out overvoltage absorption using spark gap, does not possess the overvoltage to phase and phase and absorbs, only overvoltage portion over the ground
Part absorbs, and does not have real effect to whole power system and other weak isolating equipment.
Utility model content
For the problems referred to above, this utility model provides a kind of novel protected arrester handcart, and it can overcome NTC defect,
Can have the protection of phase and phase overvoltage simultaneously, solve the problems, such as the resonance overvoltage of power system.
For reaching above-mentioned purpose, embodiment of the present utility model adopts the following technical scheme that：
A kind of novel protected arrester handcart, non-including Mume flower contact, contact arm, connection row, disjunctor insulator, Part I
Linear damping resistance, Part II nonlinear damping resistor, installing plate, framework and chassis；Described Mume flower contact and contact arm
It is connected, described contact arm is fixed on connection row；Described connection row is fixed with disjunctor insulator, and described disjunctor insulator is fixed on
On framework, described installing plate is arranged on framework；Described Part I nonlinear damping resistor right angle setting, one end is fixed on even
On running in, the other end is fixing on a mounting board；Described Part II nonlinear damping resistor is horizontally mounted, and one end is fixed on installation
On plate, the other end is fixed on framework；Described Mume flower contact, contact arm, connection row, disjunctor insulator, the non-linear resistance of Part I
Buffer resistance, Part II nonlinear damping resistor, installing plate and framework are all installed and are fixed with chassis.
According to one side of the present utility model, described Mume flower contact, contact arm, connection row, disjunctor insulator, Part I
