Fully-insulated frame integrated type capacitor provided with unshelled capacitor units and mounting method

Abstract

The present invention provides a fully-insulated frame integrated type capacitor provided with unshelled capacitor units and a mounting method. The capacitor comprises an oil tank, wire outgoing sleeves, a capacitor core body and insulating oil. The capacitor is characterized in that the capacitor core body includes a fully-insulated frame and a plurality of capacitor units disposed in the frame;the capacitor units are unshelled capacitor units; the capacitor units are fixed in the fully-insulated frame through limiting plates; the fully-insulated frame is made of a fiberglass composite material; the frame is formed by means of the connection of insulating connection sheets and insulating bolts; the whole frame is fully insulated; and capacitor oil is adopted as the insulating oil. The capacitor units are not provided with small outer shells, the limiting plates are used to fix the capacitor units in the frame, so that the capacitor core body can be formed, and therefore, the capacitor units will not come out of the frame after being loaded during transportation or work; and the size and weight of the capacitor units can be reduced, so that the size and weight of the entire capacitor device can be reduced.

Description

technical field [0001] The invention belongs to the field of collective capacitors, and in particular relates to a fully insulated frame collective capacitor using a capacitor unit without a shell and an installation method. Background technique [0002] Collective capacitors are mainly composed of capacitor units, capacitor core frames, fuel tanks, insulating oil, connecting wires, and outlet bushings. The capacitor core frame is usually made of steel profiles through welding. In order to ensure the insulation between the capacitor core and the outer fuel tank, a certain insulation gap must be ensured between the inner wall of the fuel tank and the steel frame, which leads to the overall weight of the capacitor. larger. [0003] Patent No. 201410847445.3 discloses a collective capacitor with insulated capacitor cores, including mutually insulated metal frames, capacitor units, large case shells, and bushings. The capacitor units are mounted on the metal frame, and the meta...
