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 the control switch technical field.
Background technology:
Existing separating switch changement, Main Problems are exactly that the reliability of commutation mechanism is difficult to satisfy the actual requirement of using.
Summary of the invention:
The present invention overcomes the deficiency that prior art exists, the Fast synchronization commutation mechanism that provides a kind of separating switch to use, and whole switch reliability of operation has improved in this mechanism, can realize the Fast synchronization commutation.
The objective of the invention is to realize by following measures:
The Fast synchronization commutation mechanism that a kind of separating switch uses, it is characterized in that: this mechanism comprises fixed disc, commutation lever and commutation cam; Described commutation cam is installed on the fixed disc with one heart, commutation cam and fixed disc are equipped with center mounting hole, the commutation cam is provided with three groups of arc raised lines, and three groups of arc raised lines evenly distribute along commutation cam circle perimeter surface, with one group of commutation lever of every group of corresponding connection of arc raised line;
Every group of arc raised line comprises four concentric cam lines, article four, cam line misplaces successively and arranges, every central angle corresponding to cam line length equates, corresponding with it, every group of commutation lever comprises that four are changed lever, and the front end of every reverse lever places on the cam line by a commutation roller, and the rear end of every reverse lever is provided with a looping pit, the rear portion of reverse lever is hinged on the fixed disc, and reverse lever radially arranges along the commutation cam.
The head end of described commutation lever and coupled commutation roller all adopt the metallic conduction material to make, and the looping pit of commutation lever rear end also adopts the metallic conduction material to make, and then make for insulating material the outside.
The front portion of described commutation lever is provided with the U-shaped bending.In order to its front portion is raised, be convenient to install the commutation roller.
The homonymy of four cam lines of every group 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.The commutation roller is connected to commutation lever front end by the commutation roller pin.
The present invention has following advantage compared to existing technology:
The present invention is applicable to high voltage, large current separation switch uses, and how fast commutation is insider institute problems of concern always.The present invention adopts rational mechanical structure, has realized the purpose of quick separation commutation, and is most suitable in the simultaneously and rapidly separation of high-voltage great-current.
The employing of commutation lever of the present invention composite construction, improved whole switch reliability of operation; Can within a few tens of milliseconds, finish the whole commutation action of separating switch.
This mechanism can guarantee the three-phase synchronous commutation of separating switch, has guaranteed the reliability of whole transformer work.
The composite construction that commutation lever of the present invention adopts has been guaranteed the operational reliability of commutation lever.
Description of drawings:
Fig. 1 is the structural representation of the Fast synchronization commutation mechanism of separating switch use.
Fig. 2 is commutation lever schematic diagram.
Among the figure: the 1-fixed disc; The 2-cam that commutates; The 3-reverse lever; 4-commutation roller; The 5-cam line; 6-looping pit (A point); 7-connects hinge; The bending of 8-U shape; 9-installing hole (pivot point); 10-commutation lever shank; 11-commutation roller pin.
Embodiment:
The invention will be further described below in conjunction with accompanying drawing.
The structure of commutation of the present invention mechanism as shown in Figure 1 and Figure 2.
The groundwork principle is as follows:
Commutation of the present invention mechanism is suitable for the three-phase and four-line alternating current, this three-phase and four-line is uniformly distributed on the circumference of round fixed disk 1, the joint of each line contacts with a cam line 5 of commutation cam 2 respectively by commutation lever 3, commutation cam 2 is integrally formed with power input shaft, be furnished with three groups at commutation cam 2, every group of four cam lines of arranging with one heart 5 have 12 cam lines 5 altogether, and these 12 cam lines 5 contact with 12 connector lugs respectively.The length of every cam line 5 has determined the time of commutation.
When the needs commutation, pass through power input shaft, drive commutation cam 2 fast rotational, commutation cam 2 rotary actuation commutation rollers 4 move up and down, the moving up and down of the latter ordered about " A " point by pivot point and moved up and down, and " A " point links to each other with vacuum tube by looping pit 6, therefore, the movement of " A " point has realized the folding of contact point in the vacuum tube, reaches the purpose of commutation.
Characteristics: the length of the length of each bar cam line and rising string, decline string in the commutation cam among the present invention all needs to design according to concrete designing requirement.
The reverse lever two ends are that metal material is made, so that conduction, the centre then is to adopt nonmetallic materials to make, and has so both guaranteed the intensity of leverage; Guaranteed again simultaneously the insulating properties of whole mechanism.
