Abstract
The invention provides a fast and synchro reversing mechanism. The mechanism improves operation reliability of a whole switch and can achieve fast reversing. The reversing mechanism comprises a fixing disk, reversing levers and a reversing cam. The reversing cam is concentrically placed on the fixing disk. Both the reversing cam and the fixing disk are provided with a central mounting hole. Three sets of arch-shaped raised bars are placed on the reversing cam, and are evenly distributed along the circumference surface of the reversing cam. Each set of arch-shaped raised bars is correspondingly connected with a set of reversing levers. Each set of arch-shaped raised bars comprises four homocentric cam lines. The four homocentric cam lines are sequentially laid in a dislocation mode. The central angles corresponding to the length of each cam line are equal, and correspondingly, each set of reversing levers comprises four reversing levers. The front end of each reversing lever is placed on one cam line through a reversing rolling wheel. A ring hole is placed at the rear end of each reversing lever. The rear portions of the reversing levers are hinged on the fixing disk, and the reversing levers are placed along the reversing cam and placed in a radial direction.
Description
technical field:
The present invention relates to the Fast synchronization commutation mechanism that a kind of separating switch uses, belong to control switch technical field.
background technology:
Existing separating switch changement, the subject matter of existence is exactly that the reliability of commutation mechanism is difficult to meet the actual requirement used.
summary of the invention:
The present invention is the deficiency overcoming prior art existence, the Fast synchronization commutation mechanism providing a kind of separating switch to use, and this mechanism improves whole switch reliability of operation, can realize Fast synchronization commutation.
The object of the invention is to be realized by following measures:
The Fast synchronization commutation mechanism that separating switch uses, is characterized in that: this mechanism comprises fixed disc, commutation lever and commutation cam; Described commutation cam is arranged on fixed disc with one heart, commutation cam and fixed disc are equipped with center mounting hole, commutation cam is provided with three groups of arc raised lines, and three groups of arc raised lines are uniformly distributed along commutation cam circle perimeter surface, correspondingly with often organizing arc raised line connects one group of commutation lever;
Often organize arc raised line and comprise four concentric cam lines, article four, cam line misplaces arrangement successively, central angle corresponding to every root cam line length is equal, correspond, often organize commutation lever to comprise four and change lever, the front end of every root reverse lever is placed on a cam line by a commutation roller, and the rear end of every root reverse lever is provided with a looping pit, the rear portion of reverse lever is hinged on fixed disc, and reverse lever is arranged along commutation cam radial direction.
Head end and the coupled commutation roller of described commutation lever all adopt conductive metal material to make, and the looping pit of commutation lever rear end also adopts conductive metal material to make, and outside is then for insulating material is made.
The front portion of described commutation lever is provided with U-bend folding.In order to its front portion is raised, be convenient to commutation roller is installed.
The homonymy often organizing four cam lines of arc raised line is equipped with is convenient to the upper and lower ramp type rising string of commutation roller and decline string.Commutation lever rear portion is its shank.Commutation roller is connected to commutation lever front end by commutation roller pin.
the present invention compared to existing technology tool has the following advantages:
The present invention is applicable to high voltage, big current separating switch uses, and how fast commutation is the problem that insider pays close attention to always.The present invention adopts rational mechanical structure, achieves the object of quick separating commutation, most suitable in the separation simultaneously and rapidly of high-voltage great-current.
Commutation lever of the present invention have employed composite construction, improve whole switch reliability of operation; The whole commutation action of separating switch can be completed within a few tens of milliseconds.
This mechanism can ensure the three-phase synchronous commutation of separating switch, ensure that the reliability of whole transformer work.
The composite construction that commutation lever of the present invention adopts, ensure that the operational reliability of commutation lever.
accompanying drawing illustrates:
Fig. 1 is the structural representation of the Fast synchronization commutation mechanism that separating switch uses.
Fig. 2 is commutation lever schematic diagram.
In figure: 1-fixed disc; 2-commutates cam; 3-reverse lever; 4-commutation roller; 5-cam line; 6-looping pit (A point); 7-connects hinge; 8-U shape bends; 9-installing hole (pivot point); 10-commutation lever shank; 11-commutation roller pin.
embodiment:
Below in conjunction with accompanying drawing, the invention will be further described.
The structure of commutation mechanism of the present invention as shown in Figure 1 and Figure 2.
Main operational principle is as follows:
Commutation mechanism of the present invention is suitable for three-phase and four-line alternating current, this three-phase and four-line is uniformly distributed in round fixed disk 1 circumferentially, the joint of each line is contacted with a cam line 5 of commutation cam 2 respectively by commutation lever 3, commutation cam 2 is integrally formed with power input shaft, commutation cam 2 is furnished with three groups, often organize four cam lines 5 of arranging with one heart, altogether 12 cam lines 5, these 12 cam lines 5 contact with 12 connector lugs respectively.The length of every bar cam line 5 determines the time of commutation.
When needs commutation, pass through power input shaft, drive commutation cam 2 fast rotational, commutation cam 2 rotary actuation commutation roller 4 moves up and down, the latter move up and down by pivot point order about " A " point move up and down, " A " point be connected with vacuum tube by looping pit 6, therefore, the movement that " A " puts achieves the folding of contact point in vacuum tube, reaches the object of commutation.
Feature: the length of the length of each cam line and rising string, decline string in commutation cam in the present invention, all needs, according to concrete designing requirement, to design.
Reverse lever two ends are that metal material is made, so that conduction, centre is then adopt nonmetallic materials to make, and so both ensure that the intensity of leverage; In turn ensure that the insulating properties of whole mechanism simultaneously.
