Abstract
The invention relates to a switching-on interlocking device of a circuit breaker operating mechanism, belonging to the technical field of high-voltage switches. The switching-on interlocking device of the circuit breaker operating mechanism comprises an interlocking plate and two connecting rods, wherein the interlocking plate is arranged below an output shaft of a circuit breaker operating mechanism and can rotate around a mounting shaft located in the middle of the interlocking plate; the right end of the interlocking plate is close to a switching-on lever and is shaped like a circular arc; one end of each of the two connecting rods is rotationally connected with the right end of the interlocking plate, and the other end of each of the two connecting rods is fixedly connected with the front end of the output shaft, so that the two connecting rods are bent to form a certain angle. After the switching-on interlocking device is used, the rotation of the switching-on lever can be limited when the circuit breaker operating mechanism is in a switching-on state, and furthermore misoperation is avoided; and meanwhile, by virtue of the interlocking plate of an eccentric structure, the interlocking plate can easily push the switching-on lever to rapidly reset, and the condition that the interlocking plate is damaged because the top of the switching-on lever is knocked when the interlocking plate is downwards pressed can be avoided, so that the maintenance rate of the interlocking plate is reduced.

Specific embodiment
With reference to specific embodiments and the drawings, the present invention is expanded on further.
As Figure 1-Figure 4, be a kind of circuit breaker operation mechanism combined floodgate interlock.
The circuit breaker operation mechanism includes the frame 1 being made up of in front and back two pieces of parallel riser 1a, 1b, and extend vertically through in
1 top of frame and in the energy storage axle 2 that is parallel to each other of left and right and output shaft 3, stretches out in the energy storage axle 2 of front vertical plate 1a equipped with band energy storage
The energy storage gear 5 of roller 4,2 bottom-right front vertical plate 1a of energy storage axle are provided with vertical 6 He of combined floodgate lever with reset function
Making electromagnet 7, realizes the stop of energy storage gear 5 by the cooperation of combined floodgate lever 6 and energy storage roller 4.
Combined floodgate interlock includes interlock plate 8 and two connecting rods 9.Interlock plate 8 is arranged on the output shaft 3 of circuit breaker operation mechanism
Lower section simultaneously can be rotated around its middle installation axle 10, and the right-hand member of interlock plate 8 is in circular arc near combined floodgate lever 6.The one of two connecting rods 9
Hold to rotate with the right-hand member of interlock plate 8 and be connected, the other end of two connecting rods 9 is then connected with the front end of output shaft 3 so that two connecting rods 9 are curved
It is curved into angled.
Deposit between output shaft 3, interlock plate 8 and two connecting rods, 9 three in the combined floodgate interlock of this circuit breaker operation mechanism
In following interaction relation：
When circuit breaker operation mechanism be in gate-dividing state when, the junction point between two connecting rods 9 is pushed so that interlock plate 8 from
Left-to-right is downward-sloping, and the left end of interlock plate 8 is located at the upper right side of combined floodgate lever 6, and keeps a spacing with combined floodgate lever 6
From as depicted in figs. 1 and 2.
After circuit breaker operation mechanism starts to close a floodgate, combined floodgate lever 6 makees suitable under the promotion of the expansion link of making electromagnet 7
Hour hands are rotated, and after energy storage roller 4 breaks away from the resistance of combined floodgate lever 6, energy storage axle 2 and energy storage gear 5 are together rotated and drive output
Axle 3 is rotated counterclockwise carries out feed motion.Afterwards, the expansion link of making electromagnet 7 shrinks rapidly so that combined floodgate lever 6 is multiple
Position is to vertical；Meanwhile, rotating counterclockwise for output shaft 3 pulls the junction point between two connecting rods 9 to upwarp so that a left side for interlock plate 8
End is downward-sloping.Aforementioned process is very of short duration, and the expansion link in making electromagnet 7 is shunk and closed a floodgate between the reset of lever 6
Can produce that certain hour is poor, after the expansion link of making electromagnet 7 shrinks, combined floodgate lever 6 can't reset rapidly, but output
Axle 3 pulls the action spot that two connecting rods 9 cause the left end of interlock plate 8 downward-sloping very rapid, it may occur that under interlock plate 8
Edge taps the situation at the top of combined floodgate lever 6.Thus, interlock plate 8 is designed to into off-centre operation structure in the present invention, its left end
Circular arc is tilted to the right from top to down.Using this structure, the lower edge of interlock plate 8 will not tap the top of combined floodgate lever 6, only
The inclined arc-shaped edges of 8 left end of interlocking plate apply one to combined floodgate lever 6 and push away along the upper right corner that can touch combined floodgate lever 6
Its power for rotating counterclockwise is moved, accelerates which to reset.The interlock plate 8 of this structure effectively prevent which because of percussion combined floodgate lever 6
Situation about being damaged occurs, and reduces the maintenance rate of device, has saved the maintenance cost of device.
When circuit breaker operation mechanism is in "on" position, output shaft 3 rotates counterclockwise the junction point made between two connecting rods 9
Upwarp, pull the right-hand member of interlock plate 8 to raise up so that interlock plate 8 is inclined upwardly from left to right, and the left end of interlock plate 8 is connected to conjunction
The right side of brake lever rod 6, limits the rotation of combined floodgate lever 6, as shown in Figure 3 and Figure 4.Using after this device so that breaker operator
When mechanism is in "on" position, the rotation for limiting combined floodgate lever 6 by interlock plate 8 prevents the generation of maloperation, it is ensured that transmission ＆ distribution
Electric line safety and personal safety.
