Technical field
The invention belongs to technical field of electrical equipment, and machine is operated more particularly to a kind of energy-stored spring of low voltage isolation switch
Structure.
Background technology
It needs to cut off the power when electrical equipment repairs, maintenance part is made to be isolated with live part, and keep effective isolation
At this moment distance just needs to use low voltage isolation switch.Currently used low voltage isolation switch includes mainly shell, switch contact machine
Structure, contacts cover, manual operation axis and handle；Wherein switch contact mechanism is located at the inside of shell；Contacts cover setting is switching
The upper end of contact mechanism, and the switch contact actuator in switch contact mechanism runs through setting in contacts cover in a movable manner
On trepanning in；There are one operating lever, the outer ends of operating lever and opening on the outside of contacts cover for the lower part connection of manual operation axis
It closes contact actuator upper end side to be in contact, the upper end that axis is manually operated extends to hull outside；Handle is then connected to manual behaviour
Make the outer end of axis.When staff moves handle and carries out switching on and off operation to low voltage isolation switch, in the drive of handle
Under, manual operation axis will generate rotation, and to drive operating lever accordingly to rotate, then switch contact actuator touches driving switch
Head mechanism on contact and make its separate or be closed.But there are following points for this low voltage isolation switch：The closure of contact
Speed is related with the service speed of staff, i.e., so-called related manual operation, once service speed is excessively slow, disconnecting switch is just
It is easy to burn.
Invention content
In order to solve the above technical problem, the present invention provides a kind of energy-stored spring operating mechanisms of low voltage isolation switch, lead to
The design of overtravel compensating unit can ensure that the action of low voltage isolation switch is unrelated with manual operation.
For this purpose, technical program of the present invention lies in：
A kind of energy-stored spring operating mechanism of low voltage isolation switch is mounted on the top of low voltage isolation switch, including operation
Axis, driving lever and stroke compensating unit；

Shape protrusion；The spring installation axle is hinged in the operating shaft, is located on the upside of the driving lever；The freedom of the spring installation axle
End sets the first long strip through hole；The spring is through in the spring installation axle；The shaft is mounted on the low voltage isolation switch
Top, can radially be freely rotated；The galianconism, it is long-armed be respectively and vertically fixed in the shaft, the two is mutually parallel；
The bottom end of the first axle be fixed on it is described it is long-armed on, top is fixed on the free end of the galianconism；The first axle passes through
The first long strip through hole being arranged in the spring installation axle；The long-armed free end is equipped with the second strip hole, second axis
It can be slided along second strip hole under the promotion of the driving lever；The long-armed bottom, which is fixed, is formed with cylindrical protrusions.
Specifically, the bottom of second axis is formed with bottom plate or fixture block；It is formed on the second strip hole inner wall
There is the groove to match with the bottom plate or fixture block；Bottom plate or fixture block slide along the groove.
Or following connection type can also be changed into：Second axis bottom sets slot, and the inside of second strip hole is set
There are track, slot to slide along the track.
The energy-stored spring operating mechanism of the low voltage isolation switch be using the idle stroke in spring installation axle and rotation axis come
Ensure that the operation speed of operating personnel is unrelated with the action of switch, thus contact can be made quickly to divide, close, avoid the occurrence of and keep apart
Close contact burnout failure.In addition, also have it is reasonable in design, simple, at low cost, without to former low voltage isolation switch structure into
The advantages that row change.
Description of the drawings
Fig. 1 is the stereogram of the energy-stored spring operating mechanism of low voltage isolation switch provided by the invention；
Fig. 2 is the working state figure of the energy-stored spring operating mechanism of low voltage isolation switch provided by the invention.
Specific implementation mode
Technical scheme of the present invention is described in detail below in conjunction with the drawings and specific embodiments.
As shown in Figure 1, 2, the energy-stored spring operating mechanism of a kind of low voltage isolation switch is mounted on the top of low voltage isolation switch
Portion, including operating shaft 1, driving lever 2 and stroke compensating unit 3；
The bottom end of operating shaft 1 is mounted on the top of low voltage isolation switch, can radially be freely rotated；
Driving lever 2 has two, orthogonal and fixed be arranged in the bottom of operating shaft 1；
Stroke compensating unit 3 includes spring installation axle 301, spring 302, shaft 303, galianconism 304, long-armed 305, first axle
306, the second axis 307 and cylindrical protrusions 308；Spring installation axle 301 is hinged in operating shaft 1, is located at 2 upside of driving lever；Spring
The free end of installation axle 301 sets the first long strip through hole 309；Spring 302 is through in spring installation axle 301；Shaft 303 is mounted on low
The top for pressing disconnecting switch, can radially be freely rotated；Galianconism 304, long-armed 305 are respectively and vertically fixed in shaft 303, and two
Person is mutually parallel；The bottom end of first axle 306 is fixed on long-armed 305, and top is fixed on the free end of galianconism 304；First axle
306 pass through the first long strip through hole 309 being arranged in spring installation axle 301；Long-armed 305 free end is equipped with the second strip hole 310,
Second axis 307 can slide under the promotion of driving lever 2 along the second strip hole 310；Long-armed 305 bottom is fixed and is formed with circular cylindrical projection
Play 308.
Specifically, the bottom of the second axis 307 is formed with bottom plate or fixture block；It is formed on second strip hole, 310 inner wall
The groove to match with bottom plate or fixture block；Bottom plate or fixture block slide along the groove.
Or following connection type can also be changed into：Second axis, 307 bottom sets slot, and the second strip hole 310 is internally provided with
Track, slot slide along the track.
In use, the energy-stored spring operating mechanism integral installation of low voltage isolation switch is on the top of existing low voltage isolation switch
Portion, and the cylindrical protrusions 308 of long-armed 305 bottom are in contact with the medial surface of low voltage isolation switch upper switch contact actuator 4.
When staff moves handle in the counterclockwise direction and divides low voltage isolation switch or when closing operation, in the drive of handle
Under, operating shaft 1 will generate the rotation of the same direction, to drive the second axis 307 sliding in the second strip hole 310 by driving lever 2
Dynamic, until when the end of the second strip hole 310, idle running is covered, and driving lever 2 begins through the second axis 307 and pushes long-armed 305 to occur to turn
It is dynamic, while shaft 303 drives galianconism 304 also to rotate synchronously, first axle 306 starts compressed spring 302, and spring 302 is in
Compressive state stores energy；When operating shaft 1 and galianconism 304, long-armed 205 are positioned at same straight line, reach mechanism dead-centre position
When, 302 energy storage of spring is completed, and continues to external force, dead point is crossed by mechanism, and spring 302 releases energy, and 306 moment of first axle is pushed away
Dynamic, shaft 303 rotates, and drives long-armed 305 rotation, cylindrical protrusions 308 to shift one's position rapidly, thus contact is driven quickly to separate
Or it is closed.
