Embodiment
As shown in Figure 1, patent of the present invention comprise fuse end cap 1, fuse 2, go out line interface 3, inlet wire interface 4, earthing module 5.
As shown in Figure 1, 2, earthing module 5 is cast and is formed together with fuse 2, and outer surface has sprayed conductor or semiconductor interface stratum equally, and this has also guaranteed that internal electric field distribution is not arranged by external equipment and affected.Outlet ground connection static contact seat 5a and grounding static contact seat 5b are in earthing module 5.The moving contact 5c coordinating with outlet ground connection static contact seat 5a and grounding static contact seat 5b is driven by ground connection drive rod 5d.
Ground connection drive rod 5d moves up and down by guide flange 5e, simultaneously in guide flange 5e inside, conductive contact finger is also installed, and when ground connection, electric current flow through ground connection drive rod 5d, conductive contact finger and guide flange 5e, flow into earthing bar.Ground connection drive rod 5d, by attended operation mechanism, drives moving contact to move up and down, and drives moving contact 5c with outlet ground connection static contact seat 5a and grounding static contact seat 5b while ground connection (as Fig. 2) or separate (as Fig. 1) simultaneously.
Ground connection drive rod 5d both ends have processed locating platform, and locating platform can guarantee accurately to coordinate with ground connection static contact seat 5a and 5b after three-phase moving contact 5c connects.Integrated moving contact 5c and ground connection drive rod 5d, not only exempted the complicated mutual interlocking gear of fuse two-terminal-grounding, when assembling, between three-phase, can also mutually locate, while realizing assembling without adjusting with positioning tool.Between ground connection drive rod 5d and guide flange 5e, seal by sealing ring (being not limited to) between guide flange 5e and earthing module cavity wall 5f, make earthing module 5 inner chamber body with outside isolated, built-in electrical insulation dielectric behavior is not subject to extraneous weather influence.
It is shown that the form of implementation of earthing module 5 is not limited to accompanying drawing 1 or 2, also can have following execution mode:
As shown in Figure 3, while implementing which, moving contact 5c is directly integrated in ground connection drive rod 5d, and outlet ground connection static contact seat 5a becomes above-below direction to arrange with grounding static contact seat 5b.Guide flange 5e inside is provided with conductive contact finger equally, and electric current flow through ground connection drive rod 5d, conductive contact finger and guide flange 5e when ground connection, flow into earthing bar.When ground connection closing operation, operating mechanism drives ground connection drive rod 5d and moving contact 5c to move downward by guide flange 5e, first contacts with outlet ground connection static contact seat 5a, completes cable side ground connection.Ground connection drive rod 5d and moving contact 5c continue to move downward and have contacted fuse inlet wire side joint ground with grounding static contact seat 5b.When ground connection is divided operation, operating mechanism drives ground connection drive rod 5d and moving contact 5c to move upward by guide flange 5e, first separates with grounding static contact seat 5b, then separates until moving contact nominal operation position with outlet ground connection static contact seat 5a.Deciliter order of moving contact 5c and grounding static contact 5a and 5b is without particular determination.
Go out line interface 3 according to standardization of casing size design, can with the direct abutting joint of normal sleeve.
Inlet wire interface 4 can be installed by the direct self-align grafting of locating cone 4b with on-load switch or other electrical module.On mounting flange 4c, leave bolt hole, assembly crewman only need tighten set bolt according to the moment of torsion of specifying can complete fuse installation, without adjusting installation site, has greatly simplified assembling process, has reduced assembly difficulty.
