Abstract
The invention relates to an isolation switch conductor. The isolation switch conductor comprises a static contact part and a moving contact part which is matched with the static contact part to achieve switch-on and switch-off, wherein the static contact part comprises a frame-shaped static contact seat; the inner walls of two sides of the static contact seat are provided with ohm-shaped contact fingers; a compression spring is arranged between a contact finger and the inner wall of the static contact seat; the upper end and the lower end of the static contact seat are provided with guide plates, and the front end of each guide plate bends outwardly and is opened; the moving contact part comprises a rectangular frame-type contact knife which can be embedded in the contact finger; the upper end and the lower end of the contact knife are respectively provided with guide roller wheels through supports; when in switch-on, the moving contact part moves towards the static contact part; the upper guide roller wheel or the lower guide roller wheel of the contact knife contacts with the corresponding static contact guide plate in priority; and when the guide lower contact of the guide plate is shoved off and is embedded in the ohm-shaped contact fingers, switch-on pressure is provided by the elastic deformation of the compression spring.
Description
Technical field
The present invention relates to a kind of isolating switch conductor, particularly a kind of structure is simple, quality of fit is low and be easy to find the open isolating switch conductor of potential faults.
Background technology
Isolating switch is mainly used for needing the part had a power failure reliably to isolate with live part, to ensure the safety of service work in high voltage distribution installation.Traditional isolating switch conductor comprises a pair can be fitted together to or be separated the moving contact and fixed contact that realize divide-shut brake mutually, and fixed contact is cylindrical tube shape, and moving contact comprises holder, establishes telescopic sliding guide in holder, and fixing quincunx fingertip installed outward by holder.Drive fixed contact to move to moving contact by operating mechanism during combined floodgate, the relative holder of sliding guide and fingertip inside contract, and fixed contact is stretched in fingertip and forms Multi-contact, realize feed motion.The shortcoming of this kind of structure is: number of spare parts is many, and quality of fit requires high, very high to the requirement of production, commissioning staff; It is enclosed construction, is unfavorable for that field observation is debugged, not easily finds potential faults.
Summary of the invention
The technical problem to be solved in the present invention is to provide that a kind of structure is simple, quality of fit is low and is easy to find the open isolating switch conductor of potential faults.
For solving the problems of the technologies described above, technical scheme of the present invention is: a kind of isolating switch conductor, comprise stationary contact head and realize the moving contact portion of divide-shut brake with stationary contact head fits, its innovative point is: described stationary contact head comprises shaped as frame fixed contact pedestal, the both sides inwall of this fixed contact pedestal establishes ohm-shaped fingertip, between fingertip and fixed contact pedestal inwall, establish Compress Spring, the upper and lower side of described fixed contact pedestal establishes guide plate, and the outside bending in front end of described guide plate is opened; Described moving contact portion comprises the rectangular frame-contact knife that can embed in fingertip, and the upper and lower side of this contact knife has guide roller respectively by support installing.
Further, be provided with horizontally disposed contact knife centering plate on the upside of described contact knife, this contact knife centering plate is isosceles trapezoid.
The invention has the advantages that: during use, stationary contact head is fixed on the insulator of quiet side, moving contact portion is fixed on the insulator of dynamic side by folding-jib conducting rod, drives folding-jib conducting rod launch or stack the divide-shut brake action realizing moving contact portion and stationary contact head by operating mechanism.During combined floodgate, moving contact portion moves to stationary contact head, the upper guide roller of contact knife or lower guide roller preferentially contact the fixed contact guide plate corresponding with it, and under the guiding of guide plate, contact struts and embeds in ohm-shaped fingertip, provides closing pressure by the elastic deformation of Compress Spring.Contact knife centering plate on the upside of contact knife, when contact knife stretches in fingertip, just embeds in framework fixed contact pedestal, carries out guiding centering to the horizontal direction of contact knife, avoids fingertip to damage and monolaterally stressedly causes local pyrexia more greatly.

Embodiment
Fig. 1 shows isolating switch structural representation of the present invention, comprises a pair insulator 1,2, the insulator 1 of side establishes stationary contact head 3, the insulator 2 of opposite side connects moving contact portion 4 by folding-jib conducting rod 5.Folding-jib conducting rod 5 by operating mechanism drive launch or folding pack up thus promote moving contact portion 4 to coordinate with stationary contact head 3 and realize divide-shut brake.
Fig. 2 to Fig. 4 shows the structure of stationary contact head 3, it comprises fixed contact pedestal 31, fingertip 32, guide plate 33 and Compress Spring 34, this fixed contact pedestal 31 is shaped as frame, its both sides inwall is connected with the fingertip 32 that ohm-shaped opens, Compress Spring 34 is established between fingertip 32 and fixed contact pedestal 31 inwall, a pair guide plate 33 is bolted on the upper and lower side of fixed contact pedestal 31, and front end is in opened condition outward-dipping.
As shown in Figure 5,6, moving contact portion 4 comprises contact knife 41, guide roller 42, support 43 and contact centering plate 44, contact knife 41 is rectangular frame-, the upper and lower side of this contact knife 41 is provided with guide roller 42 respectively by support 43, contact centering plate 44 is other shapes on isosceles trapezoid or tape guide limit, both sides, and it is horizontally set on the upper end of contact knife 41.
During combined floodgate, as shown in Figure 7, moving contact portion 4 moves to stationary contact head 3, the upper guide roller of contact knife 41 or the lower orienting roll 2 fixed contact guide plate 33 that preferentially contact is corresponding with it, under the guiding of guide plate 33, contact knife 41 struts and embeds in ohm-shaped fingertip 32, provides closing pressure by the elastic deformation of Compress Spring 34.Contact centering plate 44 on the upside of contact knife 41, when contact knife 41 stretches in fingertip 32, just embeds in framework fixed contact pedestal 31, carries out guiding centering to the horizontal direction of contact knife 41, avoids fingertip to damage and monolaterally stressedly causes local pyrexia more greatly.
