Technical field
The present invention relates to the fastening apparatus of electrical network assembly field, particularly relate to a kind of cartridge fuse or disconnecting link anti-shedding mechanism.
Background technology
Along with the fast development of Chinese national economy and improving constantly of material life, people are more and more higher to the dependence of electric power, and how safe and reliable the electric energy of high-quality is supplied with to the user is the substantial responsibility of power supply department.For the power distribution network as the crucial ring of electric power system, the power grid maintenance personnel carry out live line working effective assurance of the problems referred to above just to power distribution network.
Realize uninterrupted power supply in order to improve power supply reliability, on-load is changed the drop type cartridge fuse and isolating switch (disconnecting link) is a conventional content of live working of distribution network project.In order to prevent in operation process when load has not shifted, cartridge fuse, disconnecting link come off suddenly produced arc light to operating personnel and equipment generation harm, generally adopt at present insulating cord binding fixedly cartridge fuse and moving contact of disconnecting link, yet not only there is security risk in this mode, also there is the large shortcoming of live line working maintainer labour intensity simultaneously.
Summary of the invention
For above-mentioned existing insulating cord binding fixedly cartridge fuse and the moving contact of disconnecting link of generally adopting, not only there is security risk in this mode, also has the problem of the shortcoming that maintainer's labour intensity is large simultaneously, the invention provides a kind of cartridge fuse or disconnecting link anti-shedding mechanism.
For addressing the above problem, cartridge fuse provided by the invention or disconnecting link anti-shedding mechanism solve problem by following technical essential: cartridge fuse or disconnecting link anti-shedding mechanism, comprise framework, hold-down bolt and movable holddown, described framework comprises web, upper flange and lower wing plate, described upper flange and lower wing plate are separately positioned on the two ends of web, and upper flange is all vertical with respect to web with lower wing plate, be provided with internal thread hole on described upper flange, described hold-down bolt becomes threaded engagement with internal thread hole, described movable holddown is between upper flange and lower wing plate, and movable holddown and hold-down bolt are articulated and connected.
During this arranges, between movable holddown and lower wing plate, part is the clamping part of cartridge fuse or disconnecting link, cartridge fuse to be held or disconnecting link is placed on clamping part, by rotatably compressing bolt, regulate the distance between movable holddown and lower wing plate, realize the holding function of the present invention to cartridge fuse or disconnecting link.
Further technical scheme is:
Described movable holddown and upper flange are parallel to each other, and upper flange also is provided with along the casting lug thereon of web length direction near an end of web, described casting lug thereon between movable holddown and lower wing plate, and casting lug thereon and framework bonded to each other.
The casting lug thereon arranged is fixing for laminar disconnecting link, because casting lug thereon is nearer with respect to the distance of movable holddown and lower wing plate, when running into laminar disconnecting link, the stroke that hold-down bolt is less with respect to upper flange just can be fixed in laminar disconnecting link on the present invention, is conducive to improve operating efficiency of the present invention.
On described movable holddown and lower wing plate, be provided with perpendicular to the cambered surface groove of length direction separately, and the lowermost end of cambered surface groove all intersects with the center line of hold-down bolt.
The cambered surface groove arranged is arranged to radian and treats that fixing tubular cartridge fuse or disconnecting link outer wall radian are identical, increases the contact area of the present invention and tubular cartridge fuse or disconnecting link, is conducive to improve the stability that the present invention clamps tubular cartridge fuse or disconnecting link.
The thickness of described lower wing plate, upper flange and movable holddown is all in 12 millimeters to 16 millimeters scopes, and the thickness of described web is in 18 millimeters to 25 millimeters scopes.
When this thickness setting is intended to guarantee intensity of the present invention, select thinner thickness, be conducive to save material usage of the present invention.
Also comprise adjustment disk, described adjustment disk is in the form of annular discs, and adjustment disk is fixedly connected on the end of hold-down bolt away from movable holddown, and the cross section radius of adjustment disk, in 25 millimeters to 35 millimeters scopes, and is provided with asperities on the side of adjustment disk.
The adjustment disk convenient operation librarian use hand arranged directly rotates hold-down bolt, and the asperities of setting is conducive to increase the skin-friction force between adjustment disk and hand.
The material of described framework and movable holddown is the glass fiber reinforced epoxy resin based composites.
The glass fiber reinforced epoxy resin based composites is according to physics, stable chemical performance, the characteristics that insulation property intensity is high are arranged.
The present invention has following beneficial effect:
1, in the present invention, the hold-down bolt arranged by adjusting, cartridge fuse or disconnecting link are fixed between movable holddown and lower wing plate reliably, like this, when live line working, can effectively prevent that the arc light produced produces harm, the fail safe of operating personnel and equipment while being conducive to improve live line working like this to operating personnel and equipment because cartridge fuse or disconnecting link come off suddenly.
2, in the present invention, the hold-down bolt arranged by adjusting, be fixed on cartridge fuse or disconnecting link between movable holddown and lower wing plate reliably, compared to existing insulating cord fixedly cartridge fuse or the disconnecting link of utilizing, fixed efficiency of the present invention is high, is conducive to reduce operating personnel's labour intensity.
3, the present invention is simple in structure, easy to use, and processing and manufacturing easily and the cost of material is low.
