Embodiment Construction
[0022] It should be noted that, in the case of no conflict, the embodiments in the present application and the features in the embodiments can be combined with each other. The present invention will be described in detail below with reference to the accompanying drawings and examples.
[0023] Such as Figure 1 to Figure 3 As shown, the fuse cartridge assembly of this embodiment includes a grounding part of the fuse cartridge and a first driving device for the grounding part. The grounding part includes a movable contact 10 and a static contact 20, and the movable contact 10 is arranged to be movable along the axial direction of the grounding part. The first driving device is driven and connected to the movable contact 10 so that the movable contact 10 is located at the communication position where it is in contact with the static contact 20 and the disconnection position where it is separated from the static contact 20 . The first driving device includes: a housing 30 , a p...

The invention provides a fuse-wire tube assembly which comprises a grounding part of a fuse-wire tube and a first drive device. The grounding part comprises a moving contact and a static contact. The first drive device comprises a shell, a power transmission shaft, a first transmission arm, a second transmission arm and a third transmission arm, wherein the power transmission shaft is mounted inside the shell, and the two ends of the power transmission shaft extend to the outside of the shell; the first transmission arm and the outside of the shell are hinged to a first hinge point, and the first end of the first transmission arm is movably connected with the moving contact; the first end of the second transmission arm and the first transmission arm are hinged to a second hinge point; the third transmission arm is mounted on the end portion of the power transmission shaft, and the first end of the third transmission arm and the second end of the second transmission arm are hinged to a fourth hinge point; the distance between the first end of the first transmission arm and the first hinge point is larger than the distance between the second hinge point and the first hinge point. By means of the technical scheme of the fuse-wire tube assembly, the problem that the distance between contacts in a grounding device of a fuse-wire tube in the prior art is small so that the insulating property cannot be ensured can be effectively solved.
Description
technical field [0001] The present invention relates to the technical field of fuse cartridges, in particular to a fuse cartridge assembly. Background technique [0002] At present, in the field of electrical switches, in order to achieve safe operation, the combined switchgear combined with load switch and fuse barrel generally has a grounding device on the isolating switch and fuse barrel to release the charge to ensure the safety of assembly and maintenance. [0003] The distance between the two contacts of the grounding port of the existing fuse cartridge is relatively close, and the movement stroke of the grounding movable contact is short. It is necessary to add insulating oil to the insulating cavity to enhance the insulation performance to meet the insulation requirements between the two contacts. In this way, when the insulating oil leaks or deteriorates, the insulation performance will be reduced, resulting in breakdown and failure, resulting in the failure of the ...
