Abstract
The invention provides a knife switch locking and opening high voltage disconnector. A knife switch opening and closing locking mechanism comprises a locking hook; the locking hook is articulated with and arranged at a knife switch opening and closing end; the mechanism comprises the locking hook matched with a locking plate of a switch contact at the top end of an opening and closing side support insulator; a hook body matched with the locking plate is arranged on the locking hook and located at the front part of a hinged shaft; an arc limiting groove in sliding fit with a knife switch pin rod is arranged at the rear part of the locking hook; and a pull rod control hole is further formed in the locking hook. According to the technical scheme, the knife switch opening and closing locking mechanism is formed by a monomer structure, the structure of the disconnector is simplified to the greatest extent, and the disconnector has the technical advantages of easiness in assembly and debugging, reliable operation and low cost.
Description
Technical field
What patent application of the present invention related to is high voltage isolator, in particular high voltage isolator disconnecting link opening and closing locking mechanism.
Background technology
The disconnecting link opening and closing locking mechanism of high voltage isolator should have and reliably hooks lock, to break off relations performance flexibly, the formation of existing disconnecting link opening and closing locking mechanism comprises the lock matching board 50 of fixed head 60, hook 30 and make and break contact, fixed head 60 is fixed between switch tool two knife plate, hook 30 is hingedly mounted on fixed head 60, back-moving spring 40 has been mounted between jointed shaft 10 rear portion and fixed head 60, fixed head 60 is provided with hook look and divides spacing seam, and the jointed shaft front portion of hook 30 is the coupler bodies 20 coordinated with the seam of lock matching board 50.Though this structure is little, but structure and manufacture are comparatively complicated, only fixed head one communications centre bends out spacing seam, also need to go out the structure that cutter comprises lock fixing hole, hinge axis hole, pull bar handle hole and spring hanging body, building block is many, fitting operation is loaded down with trivial details, assembly and adjustment flower duration, and overall mechanical strength is difficult to reach higher technical requirement.
Summary of the invention
The goal of the invention of patent application of the present invention is to simplify disconnecting link opening and closing locking mechanism, provide a kind of component few, be easy to assemble, deciliter stable, the high voltage isolator that divides of knife switch lock reliably.The high voltage isolator technical scheme that the knife switch lock that patent application of the present invention provides divides, its main technical content is: the high voltage isolator that a kind of knife switch lock divides, disconnecting link opening and closing locking mechanism is wherein made up of latch hook, hingedly be arranged on disconnecting link opening and closing end, mechanism is formed by with deciliter latch hook that the lock-bit plate of the make and break contact on supporting insulator top, side coordinates, latch hook being positioned at hinge front portion is the coupler body coordinated with lock matching board, rear portion is provided with the spacing deep-slotted chip breaker be slidably matched with disconnecting link pin rod, and latch hook is also provided with pull bar operation hole.
The high voltage isolator technical scheme that knife switch lock disclosed in patent application of the present invention divides, be only monomer structure and form disconnecting link opening and closing locking mechanism, its structure obtains maximum simplification, and the fixed connection structure organically combined between disconnecting link two knife plate, it has and is easy to assembling, debugging, reliable in action, technological merit that cost is low, employing heavy-gauge sheeting manufactures, and be content with very little requirement of mechanical strength.

Fig. 1 is the general assembly structure chart of existing high voltage isolator.
Fig. 2 is the general assembly structure chart of patent application of the present invention, is display disconnecting link opening and closing locking mechanism, removes side knife plate wherein.
Fig. 3 is the three-dimensional structure diagram of Fig. 2.
Embodiment
The high voltage isolator that disclosed in patent application of the present invention, knife switch lock divides, disconnecting link opening and closing locking mechanism is wherein the controlling organization of chopper switch action locking and disjunction, it is made up of latch hook 6, latch hook 6 is hinged on chopper switch deciliter end position, in the present embodiment structure, latch hook 6 is hinged on a fixed lever of fixing disconnecting link two knife plate 7 end, which is provided with pull bar operation hole 1, latch hook 6 is positioned at hinge 3 front portion and is provided with coupler body 5, this coupler body 5 coordinates with deciliter the lock matching board 8 of supporting insulator top, side make and break contact is sealed, the rear portion of latch hook 6 is provided with the spacing deep-slotted chip breaker 9 be slidably matched with disconnecting link pin rod, described disconnecting link pin rod is another fixed lever 2 of disconnecting link two knife plate 7 end.Torsion spring 4 on hinge 3 acts on pin rod, i.e. on another fixed lever 2 of two knife plates 7.
