Abstract

The utility model relates to a disconnector conductor, which comprises a fixed contact part and a moving contact part which is matched with the fixed contact part to realize switching on/off, wherein the fixed contact part comprises a frame-shaped fixed contact base; ohmic contact fingers are arranged on the inner walls of the two sides of the fixed contact base; a compression spring is arranged between the contact fingers and the inner wall of the fixed contact base; guide plates are arranged at the upper end and the lower end of the fixed contact base; the front ends of the guide plates are outwards bent and opened; the moving contact part comprises a rectangular frame type contact knife which can be embedded into the contact fingers; and the upper end and the lower end of the contact knife are respectively provided with a guide idler wheel through a bracket. When the conductor is switched on, the moving contact part moves to the fixed contact part, the upper guide idler wheel or the lower guide idler wheel of the contact knife is contacted with the corresponding guide plate of the fixed contact preferentially, under the guidance of the guide plate, the contacts are opened and embedded into the ohmic contact fingers, and a switching-on pressure is provided by the elastic deformation of the compression spring.

Description

A kind of isolating switch conductor

Technical field

The utility model relates to a kind of isolating switch conductor, particularly a kind of simple in structure, quality of fit is low and be easy to find the open isolating switch conductor of potential faults.

Background technology

The part that isolating switch mainly is used for needing in the high voltage distribution installation to have a power failure is isolated reliably with live part, to guarantee the safety of service work.Traditional isolating switch conductor comprise a pair of can be chimeric mutually or separate moving contact and the fixed contact of realizing divide-shut brake, fixed contact is a cylindrical tube shape, moving contact comprises holder, establishes telescopic sliding guide in the holder, holder installs and fixes quincunx fingertip outward.Drive fixed contact by operating mechanism during combined floodgate and move, contract in sliding guide relative fixed seat and the fingertip, make fixed contact stretch into and form the multiple spot contact in the fingertip, realize feed motion to moving contact.The shortcoming of this kind structure is: number of spare parts is many, and quality of fit requires high, and is very high to production, commissioning staff's requirement; It is an enclosed construction, is unfavorable for the field observation debugging, is difficult for finding potential faults.

Summary of the invention

The technical problems to be solved in the utility model provide a kind of simple in structure, quality of fit is low and be easy to find the open isolating switch conductor of potential faults.

For solving the problems of the technologies described above, the technical solution of the utility model is: a kind of isolating switch conductor, comprise the stationary contact head and cooperate the movable contact head of realizing divide-shut brake with the stationary contact head, its innovative point is: described stationary contact head comprises shaped as frame stationary contact headstock, the both sides inwall of this stationary contact headstock is established an ohm shape fingertip, establish the compression spring between fingertip and stationary contact headstock inwall, the upper and lower side of described stationary contact headstock is established guide plate, and the outside bending of the front end of described guide plate is opened; Described movable contact head comprises the rectangle frame posture contact knife that can embed in the fingertip, and the upper and lower side of this contact knife is equipped with guide roller by support respectively.

Further, described contact knife upside is equipped with horizontally disposed contact knife centering plate, and this contact knife centering plate is an isosceles trapezoid.

Advantage of the present utility model is: during use, the stationary contact head is fixed on the quiet side insulator, the movable contact head is fixed on the moving side insulator by the folding-jib conducting rod, drives the folding-jib conducting rod by operating mechanism and launches or stack the divide-shut brake action that realizes movable contact head and stationary contact head.During combined floodgate, the movable contact head moves to the stationary contact head, the last guide roller of contact knife or the preferential contact of the following guide roller fixed contact guide plate corresponding with it, contact struts and embeds in ohm shape fingertip under the guiding of guide plate, provides closing pressure by the elastic deformation of compressing spring.The contact knife centering plate of contact knife upside just embeds in the framework stationary contact headstock in contact knife stretches into fingertip the time, and the horizontal direction of contact knife is carried out guiding centering, avoids fingertip damage and the monolateral stressed local pyrexia that causes more greatly.

Embodiment

Fig. 1 shows the utility model isolating switch structural representation, comprises on the insulator 1 of a pair of insulator 1,2, one sides establishing stationary contact head 3, connects movable contact heads 4 by folding-jib conducting rod 5 on the insulator 2 of opposite side.Folding-jib conducting rod 5 drives expansion by operating mechanism or thereby the folding promotion movable contact head 4 of packing up cooperates the realization divide-shut brake with stationary contact head 3.

Fig. 2 to Fig. 4 shows the structure of stationary contact head 3, it comprises stationary contact headstock 31, fingertip 32, guide plate 33 and compression spring 34, this stationary contact headstock 31 is a shaped as frame, its both sides inwall is connected with the open fingertip 32 of ohm shape, between fingertip 32 and stationary contact headstock 31 inwalls, establish compression spring 34, a pair of guide plate 33 is by being bolted to the upper and lower side of stationary contact headstock 31, and front end is in opened condition outward-dipping.

Shown in Fig. 5,6, movable contact head 4 comprises contact knife 41, guide roller 42, support 43 and contact centering plate 44, contact knife 41 is the rectangle frame posture, the upper and lower side of this contact knife 41 is equipped with guide roller 42 by support 43 respectively, 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, movable contact head 4 moves to stationary contact head 3, the last guide roller of contact knife 41 or the following orienting roll 2 preferential contacts fixed contact guide plate 33 corresponding with it, contact knife 41 struts and embeds in ohm shape fingertip 32 under the guiding of guide plate 33, provides closing pressure by the elastic deformation of compressing spring 34.The contact centering plate 44 of contact knife 41 upsides just embeds in the framework stationary contact headstock 31 in contact knife 41 stretches into fingertip 32 time, and the horizontal direction of contact knife 41 is carried out guiding centering, avoids fingertip damage and the monolateral stressed local pyrexia that causes more greatly.
