Fig. 1-3 shows the miniature circuit breaker with intertripping device that the utility model provides, this miniature circuit breaker comprises releasing interlock device 1, adapter 2 and circuit breaker 3, described circuit breaker 2 is located on described adapter 3, described adapter 3 output line connects the input of described circuit breaker 2, the side of adapter 3 described in the side that described releasing interlock device 1 connects described circuit breaker 2 respectively, the dropout driving lever 7 that upper end, described releasing interlock device 1 side is extended stretches in the dropout shell fragment 6 of upper end, described circuit breaker 2 side, the dropout push rod 4 of described releasing interlock device 1 contacts with described adapter 2 and connects.By setting up releasing interlock device 1, making circuit breaker 2 arcing can not be caused to occur at the charged dial-out circuit breaker 2 of operator, eliminating operator and neglect the Danger Electric shock risk brought, this circuit breaker 2 structure is simple, easy to operate, cheap.
Described releasing interlock device 1 comprises shell body, cover plate, dropout driving lever 7, fork 9, dropout push rod 4 and spring 10, multiple dividing plate is provided with in the cavity of described shell body, the cavity of described shell body is divided into multiple grid by multiple described dividing plate, described dropout driving lever 7 is located in the middle of the intrinsic upper end of described shell, described fork 9 is located at the oblique below of described dropout driving lever 7 in described shell body, described dropout push rod 4 is located at the oblique below of described fork 9 in described shell body, described spring 10 one end connects described dropout push rod 4, the other end of described spring 10 connects described dividing plate, one end of described fork 9 connects described dropout driving lever 7, the other end of described fork 9 connects described dropout push rod 4, described cover plate is covered on the cavities open of described shell body.
This miniature circuit breaker also comprises distribution bus groove 8, and described adapter 3 to be connected on described distribution bus groove 8 by buckle 5.
Described circuit breaker 2 is assemblied on described adapter 3, described releasing interlock device 1 is assembled in described circuit breaker 2 and described adapter 3 side, under described spring 10 acts on, described dropout push rod 4 is ejected, described fork 9 and dropout driving lever 7 is squeezed leans against leftmost position, the described dropout shell fragment 6 of described circuit breaker 2 is by pressure trip positions, and described circuit breaker 2 cannot close, described circuit breaker 2 off-state all the time.
Described circuit breaker 2, adapter 3 and releasing interlock device 1 are installed on described distribution bus groove 8, the fastening of described buckle 5 is on described distribution bus groove 8, described buckle 5 is pulled lower fastening promotion dropout push rod 4 and is overcome spring force telemechanical inwards, drive described fork 9 and dropout driving lever 7, described dropout driving lever 7 departs from the described dropout shell fragment 6 of described circuit breaker 2, and described circuit breaker 2 can normally closed or disconnection.
As taken off circuit breaker 2 from distribution bus groove 8, first must pull open buckle 5 and could take out circuit breaker 2, buckle 5 is once be pulled open, the driving lever 7 of releasing interlock device 1 can rebound, the dropout shell fragment 6 of circuit breaker 2 is pushed back trip positions, and circuit breaker 2 is threaded off, and switch disconnects.Now can take off circuit breaker etc. safely.
By controlling the original dropout shell fragment 6 of circuit breaker 2, in installation or leading power-off when safeguarding, usually then do not affect circuit breaker 2 operation and function thereof normally.
Because the miniature circuit breaker brand on market is different, structure and the position of the dropout shell fragment 6 on it are also not quite similar, have to stir to trip, and also have to rotate to trip, so the structure of the interlocking modules matched also is different.
In addition the transmission connecting rod mechanism in releasing interlock device 1 is by the triggering of buckle 5, and be finally transferred to the dropout shell fragment 6 of miniature circuit breaker 2, this transmission connecting rod mechanism can have double link, three connecting rods, the multiple kind of drive such as double leval jib and gear-driven form.
This miniature circuit breaker is combined with the circuit breaker 2 not limiting brand by releasing interlock device 1, adapter 3, has and takes precautions against circuit breaker 2 by charged plug by mistake, namely takes precautions against the safeguard function that circuit breaker 2 is pulled out operation under closed (connection) state.Between releasing interlock device 1, adapter 3 and circuit breaker 2 three by mechanical interlocked realization when carrying out the insertion of circuit breaker 2 or extracting operation, ensure that the leading dropout of circuit breaker 2 maybe cannot close, thus reach the object that circuit breaker 2 can plug at open position, the safety of protection operator and circuit; And to be reliably installed on distribution bus groove 8 when adapter 3 and circuit breaker 2 etc. and to lock, this releasing interlock device 1 and circuit breaker 2 are interlocked and are thrown off, and do not affect circuit breaker 2 normal ON and disjunction.
Releasing interlock device 1 is the state by controlling the original releasing interlock device 1 of miniature circuit breaker, thus realizes the disjunction controlling circuit breaker 2.
Releasing interlock device 1 is by pulling down the buckle 5 snapping in or pull open and depart from adapter, and the mechanism in releasing interlock device 1 transmits, thus controls circuit breaker 2 state.Buckle 5 is pulled down to be snapped in, and circuit breaker 2 normally can realize all functions; Buckle 5 is pulled open disengaging, and circuit breaker 2 is in trip status, and can not close, circuit is disconnected.
Releasing interlock device 1 is intervened circuit breaker 2 and to be threaded off the mode of interlock, can be converted to driving lever by slide block translation to rotate, or slide block translation is converted to the multi-motion transition forms such as driving lever translation.
Releasing interlock device 1 is intervened circuit breaker 2 and to be threaded off chain mode, can be the dropout being triggered circuit breaker 2 by the interlock of buckle 5, also can be to be linked by circuit breaker 2 or adapter 3 and the initial displacement of busbar to trigger circuit breaker 2 and thread off.
The releasing interlock device 1 of the application, adapter 2 and annex thereof can be discrete multiple parts splicing synthesis, also can be the parts of the integration combined.
The foregoing is only preferred embodiment of the present utility model; not in order to limit the utility model; all do within spirit of the present utility model and principle any amendment, equivalent to replace and improvement etc., all should be included within protection range of the present utility model.
