    摘要: A closure resistor assembly for high voltage electrical gear. The assembly includes a multiplicity of resistive electrical components aligned in a row along an axis, and a mechanism which exerts a compression force on the electrical components along the axis so as to maintain electrical contact between them. The mechanism for exerting the compression force includes a rigid tube within which the electrical components are stacked, and an energy-storing floating structure placed inside the tube at one end of the row of electrical components. The floating structure is constituted by a first piece disposed between the end of the row of electrical components and a second piece that is mounted in a fixed manner inside the tube, together with a spring that is kept in compression between the first and second pieces. The first piece is also mounted so as to be semi-moving between two abutments that are spaced-apart along the axis D.

    摘要: 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.

    摘要: A surge suppressing resistor for a disconnect switch is provided which has its interior and exterior surfaces in fluid communication with the atmosphere to achieve a greater cooling effect. A glass epoxy stacking rod is supported between the end flanges of the resistor assembly and is used when two or more resistor bodies are to be joined together to form a unitary resistor assembly. The stacking rod is stressed and compressive forces hold the resistor bodies together as a unit for structural rigidity and electrical contact.

A shield is provided at both the side of the capacitor facing the circuit breaking portion and the side of the capacitor facing the closed metal container for relaxing the electric field concentration near the capacitor. The top end of the shield is positioned so as to extend from the contacting face between the capacitor and an electrode pressing the capacitor toward the capacitor by a predetermined distance, whereby the dielectric strength of the capacitor connected in parallel with the circuit breaking portion is increased and a highly reliable and compact insulation gas filled circuit breaker of a high voltage and a large capacity use is provided.
