Description
Technical field
The utility model belongs to technical field of electrical equipment, particularly relates to a kind of energy-stored spring operating mechanism of low pressure isolating switch.
Background technology
Need cut off the electricity supply during the electric equipment maintenance, maintenance part and live part are isolated, and the isolation distance of remaining valid, at this moment just need to use the low pressure isolating switch.Low pressure isolating switch commonly used at present mainly comprises housing, switch contact mechanism, contacts cover, manual operation axle and handle; 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 the switch contact mechanism runs through in the perforate that is arranged on the 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 the contacts cover outside, and the upper end of manual operation axle extends to outside; Handle then is connected the outer end of manual operation axle.When the staff moves handle and the low pressure isolating switch is carried out branch, closing operation; Under the drive of handle; The manual operation axle will rotate, thereby drive the corresponding rotation of action bars, and the switch contact actuator makes the contact on the driving switch contact mechanism it to separate or be closed then.But there is following point in the low pressure isolating switch of this prior art: the closed speed of contact is relevant with staff's service speed, promptly so-called relevant dependent manual operation, and like this, in case service speed is slow excessively, isolating switch just is easy to burn.
Summary of the invention
In order to address the above problem, the purpose of the utility model is to provide a kind of can guarantee the action of low pressure isolating switch and the energy-stored spring operating mechanism of the low pressure isolating switch that dependent manual operation has nothing to do.
In order to achieve the above object, the energy-stored spring operating mechanism of the low pressure isolating switch that provides of the utility model comprises connecting rod, lower link, slide block, rotation axis, spring guide and energy-stored spring; An end of wherein going up connecting rod is connected the bottom of manual operation axle, the other end be positioned at the low pressure isolating switch on the medial surface of switch contact actuator contact, and be formed with a slotted hole on it; Lower link is the U-shaped plate, and one of which end lower hinge is on the surface of contacts cover, and other end opening part upper and lower surface is formed with a corresponding deep-slotted chip breaker respectively; The two ends of rotation axis are inserted respectively and are arranged on the 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 downwards to be formed with one and to be inserted in the interior boss of slotted hole on the connecting rod; One end of spring guide is connected the position that is positioned on the manual operation axle on the connecting rod, and the other end is connected the middle part of rotation axis; Energy-stored spring then is enclosed within the spring guide outside, and the one of which end is fixed on the manual operation axle, and the other end is fixed on the rotation axis middle part.
Described go up on the connecting rod slotted hole near with the contacted end of switch contact actuator.
The energy-stored spring operating mechanism of the low pressure isolating switch that the utility model provides is to utilize the idle stroke on the lower link to guarantee that operating personnel's the operation speed and the action of switch have nothing to do; So just can make contact divide fast, close, therefore the isolation switch contact burnout failure can not occur.In addition, this energy-stored spring operating mechanism have reasonable in design, simple, cost is low, and need not former low pressure isolating switch structure such as is changed at advantage.
Description of drawings
Fig. 1 is the low pressure isolating switch part-structure sketch map that the energy-stored spring operating mechanism that the utility model provides is installed.
The energy-stored spring operating mechanism structural representation of the low pressure isolating switch that Fig. 2 provides for the utility model.
Embodiment
The energy-stored spring operating mechanism of the low pressure isolating switch that the utility model is provided below in conjunction with accompanying drawing and specific embodiment is elaborated.
Like Fig. 1, shown in Figure 2, the energy-stored spring operating mechanism of the low pressure isolating switch that the utility model provides comprises connecting rod 1, lower link 2, slide block 3, rotation axis 4, spring guide 5 and energy-stored spring 6; An end of wherein going up connecting rod 1 is connected the bottom of manual operation axle 7, the other end be positioned at the low pressure isolating switch on the medial surface of switch contact actuator 8 contact, and be formed with a slotted hole 9 on it; Lower link 2 is the U-shaped plate, and one of which end lower hinge is on the surface of contacts cover 10, and other end opening part upper and lower surface is formed with a corresponding deep-slotted chip breaker 11 respectively; The two ends of rotation axis 4 are inserted respectively and are arranged on the 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 downwards to be formed with one and to be inserted in the interior boss of slotted hole on the connecting rod 19; One end of spring guide 5 is connected the position that is positioned on the manual operation axle 7 on the connecting rod 1, and the other end is connected the middle part of rotation axis 4; Energy-stored spring 6 then is enclosed within spring guide 5 outsides, and the one of which end is fixed on manual operation axle 7, and the other end is fixed on rotation axis 4 middle parts.
Described go up on the connecting rod 1 slotted hole 9 near with switch contact actuator 8 contacted ends.
When the staff divides the low pressure isolating switch along counterclockwise moving handle or during closing operation; Under the drive of handle; Manual operation axle 7 will produce the rotation of equidirectional; Thereby the openend that drives on the lower link 2 through spring guide 5 is that a clockwise direction rotates with the hinged end on contacts cover 10, and in this process, the boss on the slide block 3 will slide to right-hand member from the left end of slotted hole 9; And drive rotation axis 4 left end of deep-slotted chip breaker 11 from the lower link 2 and shift to right-hand member, the compressed energy-storage spring 6 thus.When rotation axis 4 slides to the right-hand member of deep-slotted chip breaker 11; Lower link 2 will serve as a clockwise fast rotational with hinged end on it; Make thus on the connecting rod 1 and be rotated counterclockwise rapidly with switch contact actuator 8 contacted ends; At this moment switch contact actuator 8 also will move to right rapidly, drive contact thus and separate fast or closure.
