Abstract
The present invention relates to a kind of static contact of fuse switch, including spring leaf, fixed plate and guide plate, spring leaf is between fixed plate and guide plate, one end of three is fixedly mounted on porcelain vase upper end jointly, the other end of spring leaf is formed with the concave spherical surface to be cooperated with the sphere of fuse tube moving contact, spring is installed above concave spherical surface between fixed plate, the other end of guide plate is formed with guiding prong；Mainly set in concave spherical surface outlet edge and roll trip gear, the rolling trip gear is made up of pincushion roller and fixing axle, and pincushion roller is arranged on by fixing axle at the concave spherical surface outlet edge of spring leaf.When opening a sluice gate, fuse tube moving contact leaves the concave spherical surface of spring leaf by pincushion roller, reduce and open a sluice gate frictional force between fuse tube moving contact and spring leaf concave spherical surface, only need less thrust can to realize and open a sluice gate to operate, especially suitable for remote control or remote controlled drop-out fuse.
Description
Technical field
The invention belongs to high voltage electric switch device, especially with respect to a kind of fuse switch.The present invention is applied to remote control
Or remote controlled drop-out fuse.
Background technology
The basic structure of fuse switch is by porcelain vase, the upper static contact of fuse tube and the porcelain vase of installation both ends and lower stationary contact
Head composition, upper static contact and lower static contact are connected using the fusible link between fuse tube both ends.Dynamic due to fuse tube upper end touches
There is larger contact force between head and upper static contact, needs larger thrust when it is opened a sluice gate, remote control with it is program control open a sluice gate it is more difficult.
The content of the invention
The purpose of the present invention is the problem of presence for prior art, there is provided it is a kind of that to open a sluice gate required thrust small, remote control and
The program control static contact for opening a sluice gate easy fuse switch.
Technical scheme includes spring leaf, fixed plate and guide plate, spring leaf be located at fixed plate and guide plate it
Between, one end of three is fixedly mounted on porcelain vase upper end jointly, and the other end of spring leaf is formed with the sphere phase with fuse tube moving contact
The concave spherical surface mutually coordinated, installs spring above concave spherical surface between fixed plate, and the other end of guide plate is formed with guiding prong；It is main
If being set in concave spherical surface outlet edge and rolling trip gear, the rolling trip gear is made up of pincushion roller and fixing axle,
Pincushion roller is arranged on by fixing axle at the concave spherical surface outlet edge of spring leaf.
Trip gear is rolled it is an advantage of the invention that being set in concave spherical surface outlet edge, when opening a sluice gate, fuse tube moving contact warp
The concave spherical surface that pincushion roller leaves spring leaf is crossed, reduces and opens a sluice gate frictional force between fuse tube moving contact and spring leaf concave spherical surface,
Only need less thrust can to realize to open a sluice gate to operate, especially suitable for remote control or remote controlled drop-out fuse.
Brief description of the drawings
Fig. 1 is the structural representation of the present invention.
Fig. 2 is the bottom plan structural representation of static contact in Fig. 1 of the present invention.
Embodiment
The static contact of fuse switch as shown in Figure 1, including spring leaf 4, fixed plate 6 and guide plate 5, spring leaf 4
Between fixed plate 6 and guide plate 5, one end of three is fixedly mounted on porcelain vase upper end jointly, and the other end of spring leaf 4 is formed with
The concave spherical surface 1 to be cooperated with the sphere of fuse tube moving contact, installs spring 3 above concave spherical surface 1 between fixed plate 6,
Under "on" position, the sphere of fuse tube moving contact is nested in concave spherical surface 1, and spring 3 increases the pressure between spring leaf 4 and fuse tube
Clamp force, the other end of guide plate 5 are formed with guiding prong, and the guiding prong is the guide groove of fuse tube；In the outlet edge of concave spherical surface 1
Set and roll trip gear, the rolling trip gear is made up of pincushion roller 2 and fixing axle, and pincushion roller 2 passes through fixing axle
At the outlet edge of concave spherical surface 1 of spring leaf 4.The outlet edge of concave spherical surface 1 refers to open a sluice gate direction one positioned at fuse tube
The edge of concave spherical surface 1 of side, under "on" position, the sphere and the cambered surface of the side of pincushion roller 2 of fuse tube moving contact side connect
Touch, when opening a sluice gate, fuse tube moving contact promotes pincushion roller 2 to roll, and thrust is opened a sluice gate in reduction.The external cylindrical surface of pincushion roller 2 is circular arc
Structure, increase and the matching property of fuse tube moving contact sphere, the endoporus of pincushion roller 2 and the dynamic cooperation of fixing axle, fixed both ends of the shaft
It is fixedly mounted on spring leaf 4, as shown in Figure 2.
