The connected mode of connector and breaker mechanism side plate is to realize slide down dynamic formula structure on the breaker mechanism side plate in the middle of described.Connector and breaker open operation lockplate junction are provided with and are used for that the breaker open operation lockplate is corresponding to move up and down in the middle of described
The type groove.
The beneficial effects of the utility model are: the mechanical interlocks of described a kind of circuit breaker and tri-station isolating switch; be mainly used in mutual mechanical interlocking function between the primary element circuit breaker of this equipment and the tri-station isolating switch; realize the acceptance and the distribution of the electric energy of 3～24kV electrical power distribution system; electric line or load controlled, protect and monitor finish its mutual locking, have characteristics such as perfect in shape and function, simple in structure, reliability height in when operation.
Description of drawings
Fig. 1 is a structural principle schematic diagram of the present utility model;
Fig. 2 is the utility model schematic diagram when realizing and move.
Among the figure: the 1-Three-Position Switch Operate Institutions; 2-handle hole baffle plate; Connector in the middle of the 3-; 4-breaker mechanism side plate; The sincere son of 5-breaker closing; 6-breaker open operation lockplate; 7-closing locking spare; The 8-connecting lever.
Embodiment
Below in conjunction with accompanying drawing principle of the present utility model and feature are described, institute gives an actual example and only is used to explain the utility model, is not to be used to limit scope of the present utility model.
As Fig. 1, shown in 2, the mechanical interlocks of described a kind of circuit breaker and tri-station isolating switch, comprise breaker mechanism side plate 4 and adhere to a whole set of structural member on it, be characterized in: described breaker mechanism side plate 4 tops link to each other with Three-Position Switch Operate Institutions 1, connector 3 in the middle of breaker mechanism side plate 4 is provided with, the upper end of middle connector 3 links to each other with the handle hole baffle plate 2 of Three-Position Switch Operate Institutions 1, the lower end of middle connector 3 connects with breaker open operation lockplate 6, breaker open operation lockplate 6 links to each other with the breaker closing on being arranged on breaker mechanism side plate 4 sincere sub 5, closing locking spare 7 one ends link to each other with breaker open operation lockplate 6, the connecting lever 8 corresponding settings on closing locking spare 7 other ends and the circuit breaker macro-axis.
The mechanical interlocks of described a kind of circuit breaker and tri-station isolating switch, its tri-station isolating switch operation is to the locking of circuit breaker, only under the breaker open operation state, connecting lever 8 rotations are got on its macro-axis at this moment, when the handle hole baffle plate 2 of Three-Position Switch Operate Institutions 1 is rotated counterclockwise when opening, can drive in the middle of connector 3 move up, its lower end connects with breaker open operation lockplate 6, breaker open operation lockplate 6 can
Slide up and down about in the type groove, when breaker open operation lockplate 6 horizontally slipped, middle connector 3 kept motionless, and when breaker open operation lockplate 6 slided up and down, connector 3 slided up and down in the middle of driving; Breaker closing sincere sub 5 drives breaker open operation lockplate 6 and exists attached to also rotatable on the breaker mechanism side plate 4 during its rotation
Move left and right in the type groove when locking part 3 slides up and down, also drives breaker open operation lockplate 6 and exists
Slide up and down sincere sub 5 quilts of breaker closing in the type groove
The type groove pins and can not rotate, the interlock that circuit breaker can not close a floodgate when so just realizing the tri-station isolating switch operation; Its breaker operator is to the locking of tri-station isolating switch, when the handle hole baffle plate 2 of Three-Position Switch Operate Institutions 1 is not opened, middle connector 3, breaker open operation lockplate 6, closing locking spare 7 remain on Fig. 2 location status, and can carry out breaker switching-on operation this moment; When the breaker closing lock, connecting lever 8 rotations down on its macro-axis, as Fig. 2, retaining platform on the closing locking spare 7 is blocked, closing locking spare 7 can not upwards slide, breaker open operation lockplate 6, middle connector 3 can not upwards slide successively, and the handle hole baffle plate 2 of Three-Position Switch Operate Institutions 1 just can not be opened, the interlock that tri-station isolating switch just can't be operated when so just realizing breaker closing.
The above only is preferred embodiment of the present utility model, and is in order to restriction the utility model, not all within spirit of the present utility model and principle, any modification of being done, is equal to replacement, improvement etc., all should be included within the protection range of the present utility model.
