Trip gear is arranged in the breaker cabinet of Medium Voltage Switchgear, and the function of trip gear is: in making process
In any moment, if chopper is connected to sub-gate signal, moving contact can return and be maintained at open position, even switching signal still
Continuing.Which ensure that chopper can disconnect rapidly in the case of the fault that is short-circuited.
As shown in Fig. 1 and Fig. 2 and Fig. 3, trip gear includes the first installing plate 10, the second installing plate 20 and rocking bar 40.
After chopper receives sub-gate signal, the second installing plate 20 can slide on the first installing plate 10, thus jack-up rocking bar upwards
40 rotate clockwise, to activate the release lever in mechanism, so that chopper during short trouble disconnects in time.Moreover,
Trip gear can also automatically reset after chopper disconnects in time.
Specifically, the first installing plate 10 is used for serving as the base plate of trip gear, and the second installing plate 20 passes through two elastic components
50 connection the first installing plates 10.Electromagnet coil 30 is fixed on the second installing plate 20, and electromagnet coil assembly 30 passes through at least
One elastic component 50 is connected to the first installing plate 10, with all the time against rocking bar 40.Rocking bar 40 is rotatably connected to the first installation
On plate 10, thread off for triggering release lever with cut-off breaker, the side 44 of rocking bar 40 is contacted with the first spring 32.Rocking bar 40 leads to
Cross a pin 42 to be rotatably connected on the first installing plate 10, and there is first male arms 46.Also have one on rocking bar 40
Individual first male arms 46 and a recess 48, recess 48 is used for serving as instrument avoidance hole.First installing plate 10 and the second installing plate 20
On be respectively provided with the slide rail 10a being fitted to each other and axle sleeve 20a and be slidably matched.Wherein, slide rail 10a is Fructus anacardii shape.Second installation
Plate 20 can slide up and down along slide rail 10a as illustrated with respect to the first installing plate 10.Wherein, in the first installing plate 10 and
Two fixing elastic components 50 between the bottom of two installing plates 20, the elastic-restoring force of elastic component 50 is used for providing the second installing plate
20 along the active force sliding with respect to the first installing plate 10, and drive further the first spring 32 lift upwards rocking bar 40 do suitable
Hour hands rotate, and finally trigger the release lever in breaker cabinet, so that chopper during short trouble disconnects in time.
As shown in figure 4, electromagnet coil 30 includes a permanent magnet 38, housing 31 of 36, solenoid and one
Iron core 34.Wherein, solenoid 38 is radially arranged against permanent magnet 36.Permanent magnet 36 and solenoid 38 are encapsulated in interior by housing 31.
One end of iron core 34 is stretched into housing 31 and is extended axially through permanent magnet 36 and solenoid 38, and its other end is against rocking bar 40.Wherein,
The first spring 32 elastic-restoring force on electromagnet coil 30 produces active force and is set to f1, and the direction of f1 is upwards.On iron core 34
After energising, f2 is set to by the active force that the solenoid 38 of iron core 34 and its periphery setting produces, the direction of f2 is also upwards.
When the second installing plate 20 is with respect to the first installing plate 10 upward sliding, actually permanent magnet 36 upwards near iron core 34, by
There is magnetic force in permanent magnet 36, permanent magnet 36 also produces a downward active force f3.If chopper is connected to sub-gate signal, to electricity
Magnet coil 30 is energized, i.e. f1+f2 ＞ f3, and therefore electromagnet coil 30 is overall produces a power upwards, promotes the first spring
32 discharge its elastic force to trigger tripping function.If chopper completes separating brake and failture evacuation, electromagnet coil 30 power-off, f2=0,
F3 ＞ f1, therefore electromagnet coil 30 is overall produces a downward suction, and the first spring 32 is firmly drawn in electromagnetism iron wire
Circle 30 above, wait next time fault when execute tripping function.
As shown in Figure 5 and Figure 6, the breaker cabinet of Medium Voltage Switchgear includes a gripper shoe 60, and it is fixed with chopper, and
It has been rotatably coupled a release lever 80 and an energy storage bar 70, gripper shoe 60 has been further fixed on dropout dress as described above
Put.Wherein, release lever 80 has second male arms 82, and release lever 80 and rocking bar 40 coordinate so that the first male arms 46 can be
Against the second male arms 82 when rocking bar 40 rotates, thus driving release lever 80 triggering release lever to thread off with cut-off breaker.Energy storage bar
70 one end 72 can promote rocking bar 40 so that electromagnet coil 30 is resetted, and energy storage bar 70 is connected on main shaft, when moving contact and quiet
Main shaft 70 can be driven during contact separating brake to turn clockwise, so that one end 72 contacts at rocking bar 40 and drives rocking bar 40 to revolve counterclockwise
Turn.
5 and Fig. 6 the tripping function mechanism of trip gear of the present utility model and its reset are retouched below in conjunction with the accompanying drawings
State.
As shown in figure 5, any moment in making process, if chopper is connected to sub-gate signal during short trouble, thread off
Second installing plate 20 of device then with respect to the first installing plate 10 relatively upward sliding so that electromagnet coil 30 top
One spring 32 discharges elastic force, and elastic-restoring force drive rocker 40 rotate counterclockwise using the first spring 32 upwards.Then, shake
First male arms 46 of bar 40 is contacted with the second male arms 82 on release lever 80, and is further driven to the second male arms 82 and turns counterclockwise
Dynamic, thus finally making release lever 80 also rotate counterclockwise, thus triggering tripping function.Send sub-gate signal to moving contact,
Dynamic/static contact now completes separating brake.
As shown in fig. 6, after the dynamic/static contact in breaker cabinet there occurs separating brake action due to short trouble, it is right to need
Trip gear is resetted, to continue executing with tripping function in the similar fault of upper once generation.Specifically, when dynamic/static contact is sent out
After lock action estranged, main shaft 70 can be driven to rotate clockwise so that the one end 72 on main shaft 70 promotes rocking bar 40 and band shakes
Bar 40 rotate counterclockwise.The side of rocking bar 40 has a downward active force during rotate counterclockwise, thus will take off
First spring 32 of buckle device is pressed down against, to return to original state.
The trip gear for chopper that this utility model provides is due in the first installing plate 10 and the second installing plate 20
On be provided with two elastic components 50, and be also respectively provided with, on the first installing plate 10 and the second installing plate 20, the slide rail being fitted to each other
10a and axle sleeve 20a is slidably matched, and therefore, makes the second installing plate 20 relative using the elastic-restoring force of this two elastic components
Slide in the first installing plate, so that the first spring 32 on electromagnet coil assembly 30 is all the time against rocking bar 40, can with guarantee
To trigger tripping function it is ensured that chopper can disconnect rapidly in the case of the fault that is short-circuited.
