The utility model relates to a frame-type parallel capacitor device suitable for 35kV and 66kV. The capacitor comprises a capacitor frame, a combined bracket, a support, a first isolating switch, a second isolating switch, a current transformer, a reactor and a capacitor bank, wherein the reactor and the capacitor bank are arranged on the support; the capacitor frame and the combined support are arranged to be of an upper-layer structure, a middle-layer structure and a lower-layer structure respectively. The number of the capacitor frames is at least two. The capacitor banks corresponding to the same-phase power supply are arranged on the same layer of the capacitor frame; the three current transformers are respectively arranged at different layer heights of the combined bracket; the threereactors are stacked in an upper layer, a middle layer and a lower layer, the capacitor banks of the same layer are connected with the current transformers of the same layer in series, the two ends of the series capacitor banks are connected with one ends of the reactors of the same layer and one end of the first disconnecting switch respectively, and the other ends of the reactors are connectedwith one end of the second disconnecting switch. The beneficial effects are that a three-phase stacked structure is adopted, the occupied area of an original frame-type capacitor is saved by 2/3, andthe layout design of a transformer substation is optimized.
