In Gas Insulated Switchgear (GIS) substation, the spacer used for supporting conductor, isolating air chamber and insulation is a very important insulation component in GIS pipe, and it is important to study the spacer to ensure the insulation performance and quality of GIS. Local distortion of electric field distribution will be produced when electromagnetic wave propagates to spacers. In this article, the static capacitance calculated by electromagnetic simulation is used to model spacers.

In this paper, a modified equivalent circuit model (ECM), which considers the effects of an arc-shaped stator structure and saturation, is presented to calculate the characteristics of a two-degree-of-freedom direct drive induction motor (2DoFDDIM). The motor has a novel slotted solid rotor (SSR), which is slotted along the axial and circumferential directions, and copper is cast in the slots. The SSR is equivalent to a cage rotor by analyzing the current distribution using the circuit diagram. The corrected ECM parameter expressions of a cage rotor are proposed to calculate the SSR parameters. The characteristics obtained by ECM and finite element method are compared to verify the accuracy of the modified ECM. This paper provides reference for calculating the parameters of the induction motor with SSR.
