Description
Technical field
The utility model relates to the reset buffer gear of a kind of circuit breaker with magnetic flow convertor, belongs to Low Voltage Electrical Apparatus.
Background technology
Circuit breaker is divided into primary cut-out and low-voltage circuit breaker by its scope of application.Low-voltage circuit breaker claims again automatic switch, is commonly called as " air switch " and also refers to low-voltage circuit breaker, and it is a kind of existing hand switch effect, can automatically carry out again decompression, under-voltage, overload and the electrical equipment of short-circuit protection.It can be used to distribute electric energy; do not start continually asynchronous motor; power circuit and motor etc. are carried out to protection; can automatic shutdown circuit when serious overload or short circuit and the fault such as under-voltage occur for they; its function is equivalent to the combination of Fuse switch and mistake underheat relay etc.; and generally do not need to change parts after the disjunction fault current, obtain a wide range of applications.
Traditionally when circuit breaker failure need to trip, controller sends trip command makes magnetic flow convertor get its iron core, through a series of mechanisms interlock, the tripping operation of actuate operation mechanism, it is one-way operation that but magnetic flow convertor is got its iron core, iron core can self-return, need to make by mechanical mode its return.On current low-voltage circuit breaker in controller major part all utilize the return rotation of main shaft, magnetic flow convertor iron core return, be difficult for installing the shortcoming that structure is loaded down with trivial details and production cost is high by a series of structures but generally have.
As shown in Figure 1, the buffer gear that resets of magnetic flow convertor for current circuit breaker, mostly adopt two nuts to add the method that a spring shim assembles push rod, buffer spring and bent plate mutually; Because the rear portion of bent plate also can promote a signaling switch, this position is positioned at the nut place just, and bent plate is when promoting magnetic flow convertor iron core high speed return, due to the compression energy-absorbing of buffer spring, easily cause nut and sensitive switch to touch the phenomenon that arm blocks, thereby cause the controller output signal mistake.
The utility model content
For existing circuit breaker, with the buffer gear that resets of magnetic flow convertor, easily cause nut and sensitive switch shake-up arm to block, thereby cause the technological deficiency of controller output error signal, the utility model provides the reset buffer gear of a kind of circuit breaker with magnetic flow convertor, eliminated sensitive switch and touched the jammed phenomenon of arm, whole mechanism structure is simple.
Technical scheme
Realize above-mentioned technical purpose in order to solve, the buffer gear that resets of magnetic flow convertor for a kind of circuit breaker of the utility model, it comprises bent plate, it is characterized in that: described bent plate in hole through trip bolt arranged, described trip bolt head props up bent plate to the outside, hole, trip bolt bar section passes with release link and is fixed together from the opposite side to hole, buffer spring is sleeved on trip bolt, buffer spring one end props up the bent plate medial surface, the other end props up release link, and buffer spring is in compressive state.
Described release link is provided with the checknut hole, and trip bolt is locked in the checknut hole.
Spring leaf is fixed on described bent plate and can drives the bent plate rotation.
Described release link outer surface is provided with the screw thread for rotation.
Beneficial effect
The utility model has replaced the assembling mode of nut and the spring shim of original technology with a trip bolt, change the structure of original push rod simultaneously, has the following advantages:
At first. reduce the quantity of part, made assembling more efficient simple, and easily realize fitting tight, reduced the possibility got loose; Secondly, the end of trip bolt is more smooth and round and smooth, is difficult to make the shake-up arm of sensitive switch to be stuck, and has eliminated the possibility of the output error signal of telecommunication.
The accompanying drawing explanation
Accompanying drawing 1 is the reset buffer gear structural representation of existing circuit breaker with magnetic flow convertor.
Accompanying drawing 2 is the utility model structural representation.
The structural representation that accompanying drawing 3 has resetted for the utility model.
The structural representation that accompanying drawing 4 does not reset for the utility model.
Accompanying drawing 5 is explosive view of the present utility model.
Accompanying drawing 6 is the location drawing of the utility model in controller.
Embodiment
Below in conjunction with drawings and Examples, the utility model is described further.
Embodiment
As shown in accompanying drawing 2 and 5, the buffer gear that resets of magnetic flow convertor for a kind of circuit breaker, it comprises bent plate 1, described bent plate 1 in hole 101 through trip bolt 2 is arranged, described trip bolt 2 heads prop up bent plate to 101 outsides, hole, trip bolt 2 bar sections pass with release link 3 and are fixed together from the opposite side to hole 101, buffer spring 4 is sleeved on trip bolt 2, buffer spring 4 one ends prop up bent plate 1 medial surface, and the other end props up release link 3, and buffer spring 4 is in compressive state.
Described release link 3 is provided with the checknut hole, and trip bolt 2 is locked in the checknut hole.
Described release link 3 outer surfaces are provided with the screw thread for rotation.
As shown in accompanying drawing 3,4 and 6, when circuit breaks down, after the controller of switch sends trip signal, the iron core 6 of magnetic flow convertor will be got forward, promotes minute brake lever rod of operating mechanism, carries out the separating brake opening operation; After separating brake, the main shaft return of operating mechanism, promote spring leaf 5 by the cantilever 7 be fixed on main shaft, bent plate 1 is rotated, and then realizes that the iron core of magnetic flow convertor resets; In reseting procedure, because the impulsive force of main shaft is very large, buffer spring 4 absorption portion are impacted, and have reduced the possibility that magnetic flow convertor damages; The rotation of bent plate 1 has simultaneously also discharged sensitive switch 8, makes controller obtain the signal of separating brake of operating mechanism; Because the end of trip bolt 2 is more smooth and round and smooth, substantially eliminated the situation of blocking sensitive switch shake-up arm that bent plate occurs in rotary course.
The utility model has replaced the assembling mode of nut and the spring shim of original technology with a trip bolt, change the structure of original push rod simultaneously, has the following advantages:
At first. reduce the quantity of part, made assembling more efficient simple, and easily realize fitting tight, reduced the possibility got loose; Secondly, the end of trip bolt is more smooth and round and smooth, is difficult to make the shake-up arm of sensitive switch to be stuck, and has eliminated the possibility of the output error signal of telecommunication.
