Abstract
A resistor-provided UHV breaker includes a tank, a main contact unit, a resistor unit, a resistor contact unit, support members, and a displacement absorbing system. The support members are arranged between the main contact and the resistor unit to support the resistor unit relative to the main contact unit. The displacement absorbing system is arranged at both ends of the resistor unit to absorb the relative displacement of the resistor unit in its axial direction.

A resistor-provided UHV breaker comprising:
- a tank;
- a main contact unit arranged within said tank along a first direction which is parallel to an axial direction of said tank;
- a resistor unit arranged within said tank along said first direction;
- a resistor contact unit arranged within said tank along a second direction which is perpendicular to said first direction so as to cooperate with said resistor unit and thereby form a parallel circuit;
- and
- a plurality of support members arranged between said main contact unit and said resistor unit for supporting center portions of said resistor unit along said axial direction of said tank,
- wherein said support members are located at a center of said resistor unit when viewed along said first direction.

A resistor-provided UHV breaker comprising:
- a tank;
- at least one main contact arranged within said tank along a first direction;
- a resistor unit arranged within said tank along said first direction;
- at least one resistor unit arranged within said tank along said first direction and including a plurality of resistance elements and a connecting system supported by said at least one main contact for connecting each of said plurality of resistance elements to one another;
- at least one resistor contact arranged within said tank at a center thereof and along a second direction which is perpendicular to said first direction so as to cooperate with said at least one resistor unit and thereby form a parallel resistance circuit;
- and
- a plurality of support members arranged between said main contact unit and said resistor unit for supporting center portions of said resistor unit along an axial direction of said tank,
- wherein said support members are located at a center of said resistor unit when viewed along said first direction.
