Abstract
The invention discloses an energy storage spring operating mechanism for a low-voltage disconnecting switch. The operating mechanism comprises an upper connecting rod, a lower connecting rod, a slide block, a rotating shaft, a spring guide rod and an energy storage spring, wherein one end of the upper connecting rod is connected to the bottom of a manual operating shaft and the other end of the upper connecting rod is contacted with a switch contact actuator; a long hole is formed on the upper connecting rod; one end of the lower connecting rod is hinged on the surface of a contact cover and the upper and lower surfaces of the other end of the lower connecting rod are respectively provided with an arc-shaped groove; two ends of the rotating shaft are inserted into the two arc-shaped grooves respectively; one end of the slide block is hinged on the lower part of the rotating shaft and the bottom surface of the other end of the slide block protrudes downward to form a boss; one end of the spring guide rod is connected to the manual operating shaft and the other end of the spring guide rod is connected to the middle part of the rotating shaft; and the energy storage spring is sleeved outside the spring guide rod. By utilizing the energy storage spring operating mechanism, the operating speed of an operator is guaranteed by utilizing an idle stroke on the lower connecting rod and is irrelevant to a switching action, so that the contact is rapidly connected and disconnected, therefore, an accident of burning the contact of the disconnecting switch is avoided.
Description
Technical field
The invention belongs to technical field of electrical equipment, particularly relate to a kind of energy-stored spring operating mechanism of low voltage isolation switch.
Background technology
During electric equipment maintenance, need to cut off the electricity supply, make maintenance part and live part isolation, and the isolation distance of remaining valid, at this moment just need to use low voltage isolation switch.Conventional low voltage isolation switch mainly comprises housing, switch contact mechanism, contacts cover, manual operation axle and handle at present; Wherein switch contact mechanism is positioned at the inside of housing; Contacts cover is arranged on the upper end of switch contact mechanism, and the switch contact actuator in switch contact mechanism runs through in the perforate being arranged in contacts cover in a movable manner; The bottom of manual operation axle is connected with an action bars, and the outer end of action bars contacts with switch contact actuator upper end one side that is positioned at contacts cover outside, and the upper end of manual operation axle extends to outside; Handle is connected to the outer end of manual operation axle.When staff move handle and to low voltage isolation switch divide, during closing operation, under the drive of handle, manual operation axle will rotate, thereby drive the corresponding rotation of action bars, and switch contact actuator makes the contact on driving switch contact mechanism it separately or be closed then.But there is following point in the low voltage isolation switch of this prior art: the closed speed of contact is relevant with staff's service speed, i.e. so-called relevant dependent manual operation, like this, once service speed is excessively slow, isolating switch is just easy to burn.
Summary of the invention
In order to address the above problem, the object of the present invention is to provide the energy-stored spring operating mechanism of the irrelevant low voltage isolation switch of a kind of action that can guarantee low voltage isolation switch and dependent manual operation.
In order to achieve the above object, the energy-stored spring operating mechanism of low voltage isolation switch provided by the invention comprises connecting rod, lower link, slide block, rotation axis, spring guide and energy-stored spring; The one end of wherein going up connecting rod is connected to the bottom of manual operation axle, the other end be positioned at low voltage isolation switch on the medial surface of switch contact actuator contact, and on it, be formed with a slotted hole; Lower link is U-shaped plate, and its one end lower hinge is on the surface of contacts cover, and other end opening part upper and lower surface is formed with respectively a corresponding deep-slotted chip breaker; The two ends of rotation axis are inserted respectively and are arranged on lower link in two deep-slotted chip breakers; One end of slide block is hinged on the bottom of rotation axis, and other end bottom surface is outstanding to be downwards formed with one and to be inserted in the boss in slotted hole on connecting rod; One end of spring guide is connected on manual operation axle and is positioned at the position on connecting rod, and the other end is connected to the middle part of rotation axis; Energy-stored spring is enclosed within spring guide outside, and its one end is fixed on manual operation axle, and the other end is fixed on rotation axis middle part.
Slotted hole on described upper connecting rod is near the one end contacting with switch contact actuator.
The energy-stored spring operating mechanism of low voltage isolation switch provided by the invention is to utilize the idle stroke on lower link to guarantee that operating personnel's operation speed and the action of switch have nothing to do, so just can make contact divide fast, close, therefore there will not be isolation switch contact burnout failure.In addition, this energy-stored spring operating mechanism has reasonable in design, simple, cost is low, and without the advantage such as former low voltage isolation switch structure being changed to.
Accompanying drawing explanation
Fig. 1 is the low voltage isolation switch part-structure schematic diagram that energy-stored spring operating mechanism provided by the invention is installed.
Fig. 2 is the energy-stored spring operating mechanism structural representation of low voltage isolation switch provided by the invention.
Embodiment
Below in conjunction with the drawings and specific embodiments, the energy-stored spring operating mechanism of low voltage isolation switch provided by the invention is elaborated.
As shown in Figure 1 and Figure 2, the energy-stored spring operating mechanism of low voltage isolation switch provided by the invention comprises connecting rod 1, lower link 2, slide block 3, rotation axis 4, spring guide 5 and energy-stored spring 6; The one end of wherein going up connecting rod 1 is connected to the bottom of manual operation axle 7, the other end be positioned at low voltage isolation switch on the medial surface of switch contact actuator 8 contact, and on it, be formed with a slotted hole 9; Lower link 2 is U-shaped plate, and its one end lower hinge is on the surface of contacts cover 10, and other end opening part upper and lower surface is formed with respectively a corresponding deep-slotted chip breaker 11; The two ends of rotation axis 4 are inserted respectively and are arranged on lower link 2 in two deep-slotted chip breakers 11; One end of slide block 3 is hinged on the bottom of rotation axis 4, and other end bottom surface is outstanding to be downwards formed with one and to be inserted in the boss in slotted hole 9 on connecting rod 1; One end of spring guide 5 is connected on manual operation axle 7 and is positioned at the position on connecting rod 1, and the other end is connected to the middle part of rotation axis 4; Energy-stored spring 6 is enclosed within spring guide 5 outsides, and its one end is fixed on manual operation axle 7, and the other end is fixed on rotation axis 4 middle parts.
Slotted hole 9 on described upper connecting rod 1 is near the one end contacting with switch contact actuator 8.
When staff moves in the counterclockwise direction handle and low voltage isolation switch is divided or during closing operation, under the drive of handle, manual operation axle 7 will produce the rotation of equidirectional, thereby drive hinged end that the openend on lower links 2 take in contacts cover 10 to rotate as axle clockwise direction by spring guide 5, in this process, boss on slide block 3 will slide to right-hand member from the left end of slotted hole 9, and drive the left end of rotation axis 4 deep-slotted chip breaker 11 from lower link 2 to shift to right-hand member, compressed energy-storage spring 6 thus.When rotation axis 4 slides to the right-hand member of deep-slotted chip breaker 11, it is the clockwise fast rotational of axle that lower link 2 will be take hinged end on it, make thus the one end contacting with switch contact actuator 8 on connecting rod 1 be rotated counterclockwise rapidly, at this moment switch contact actuator 8 also will move to right rapidly, drive thus contact to separate fast or closure.
