Embodiment Construction
[0030] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below through specific embodiments in conjunction with the accompanying drawings.
[0031] figure 2 and image 3 It is a three-dimensional schematic diagram and a front view of a solid insulating cylinder in a preferred embodiment of the present invention. Such as figure 2 and 3 As shown, the solid insulating cylinder 61 includes a first insulating cylinder 10 , a second insulating cylinder 20 and a third insulating cylinder 30 arranged in parallel. The shapes and structures of the first insulating cylinder 10 , the second insulating cylinder 20 and the third insulating cylinder 30 are basically the same. A first accommodating cylinder 11 , a second accommodating cylinder 12 and a third accommodating cylinder 13 are provided on the outer wall of the first insulating cylinder 10 . A fourth accommodating cylinder...

The invention provides a solid insulating cylinder, which comprises a first insulating cylinder, a second insulating cylinder and a third insulating cylinder which are arranged in parallel, wherein a first accommodating cylinder, a second accommodating cylinder and a third accommodating cylinder are arranged on the outer side wall of the first insulating cylinder; a fourth accommodating cylinder, a fifth accommodating cylinder and a sixth accommodating cylinder are arranged on the outer side wall of the second insulating cylinder; a seventh accommodating cylinder, an eighth accommodating cylinder and a ninth accommodating cylinder are arranged on the outer side wall of the third insulating cylinder; the first accommodating cylinder, the fourth accommodating cylinder and the seventh accommodating cylinder are arranged along a first axis; the second accommodating cylinder, the fifth accommodating cylinder and the eighth accommodating cylinder are arranged along a second axis; and the third accommodating cylinder, the sixth accommodating cylinder and the ninth accommodating cylinder are arranged along a third axis. The solid insulating cylinder provided by the invention can achieve three-phase bus expansion without an expansion sleeve.
Description
technical field [0001] The invention relates to the field of switch cabinets, in particular to an insulating cylinder used for switch cabinets. Background technique [0002] In medium-voltage switchgear, solid insulating cylinders are usually used to insulate conductive components such as busbars, vacuum interrupters, and disconnectors from the external environment. The performance of the solid insulating cylinder directly affects the safety and reliability of the power transmission and distribution system. [0003] Chinese Patent Publication No. CN104201595A discloses a main insulator for solid insulated switchgear. figure 1 shows a schematic perspective view of one of the main insulators, as figure 1 As shown, the inlet and outlet bushings 4 and the main busbar bushings 9 are all IEC European standard tapered bushings. This design is suitable for the expansion of the busbar by using standardized outer tapered expansion bushings and busbar connectors that match it ( That...
