Description
Technical field
The invention belongs to circuit-breaker technical fields, and in particular to a kind of trip gear of low-pressure plastic shell circuit breaker.
Background technology
Above mentioned trip gear refers mainly to thermal release device, and more precisely, referring to thermal magnetic trip gear, (industry is also
Custom is called " Pyromagnetic release ").There are mainly two types of the structure types of thermal magnetic trip gear：First, by metal thermal element structure
Into overload long delay protection trip gear；Second is that the short-circuit protection wink ejector half trip gear of electromagnet form.When detecting electricity
During abnormal current in road, trip gear acts and activates circuit breaker tripping, cuts off circuit.In addition, the electric current according to breaker
Setting valve it is adjustable whether, generally can be divided into fixed and two kinds adjustable.
For the thermal magnetic adjustable tripping device in prior art, generally by the adjusting to rotary dial-up come band
It moves draw bar and uses embodiment to the adjustable of rated current gear.Due to the knot of the thermal magnetic adjustable tripping device in prior art
The position of the foregoing rotary dial-up of structure system is located at the top of draw bar, thus can undoubtedly occupy the short transverse of trip gear
Space, that is, occupy trip gear height dimension, in addition, the trip gear of this adjusting knob structure type is in breaker
There is additional space cooperation requirement in portion.Also, moving in wink in well known pyromagnetic adjustable type dropout technology can generally be held in the mouth by adjusting
The reaction spring of iron realizes the adjusting of different electric current gears, and the active force of reaction spring be in claimed circuit
What prospective current matched, specifically, protected by the cooperation between setting current, the magnetic field force and counter spring force three
Shield relation determines.The cooperation between parts is realized by using rotational structure form and uses satisfaction and reaction spring is pre-tightened
The adjusting requirement of power is blanket, but is undoubtedly existed to the cooperation requirement of helicoid by moving adjustment structure rotational structure wink
It is cumbersome (being inconvenient) in design and manufacture, because helicoid is difficult to realize self-locking under stress situation,
And it generates rotation unavoidably due to stress, short-circuit protection characteristic will certainly then be had an impact.In view of this, adjustable type structure is eliminated
Trip gear present in foregoing unfavorable factor for promoted short-circuit protection characteristic have positive effect, it is described below
Technical solution generates in this background.
The content of the invention
The task of the present invention is that providing one kind helps directly to pass through adjusting on the premise of any parts are not increased
Bar adjusts reaction spring and uses the trip gear for realizing the low-pressure plastic shell circuit breaker being adjusted to short circuit current flow setting valve.
The task of the present invention is so come what is completed, a kind of trip gear of low-pressure plastic shell circuit breaker, the low pressure is moulded
Case circuit breaker includes housing, is arranged on the in vivo operating mechanism of shell and trip gear, and the trip gear includes short circuit and moves in wink
Protection buckle releaser and the draw bar for activating the operating mechanism action, the short-circuit instantaneous protection buckle releaser include rank
Iron, adjusting rod and the reaction spring for providing restoring force for armature, the adjusting rod slide hub setting and exist in the axial direction
On housing, reaction spring connection adjusting rod and armature, when short circuit current flow flows through trip gear, described in the armature actuation
Draw bar pivots, and the draw bar unlocks operating mechanism and activates circuit breaker trip circuit, offers one on the housing
Instruction unit probes into window, there is an instruction unit on the adjusting rod, which is insinuated into the instruction unit and probes into window simultaneously
And probe into window with instruction unit and be engaged, when being adjusted axially to the instruction unit, the spring force of the reaction spring changes
And it uses and realizes that the action current value of the short-circuit instantaneous protection buckle releaser is adjustable.
In the specific embodiment of the present invention, the trip gear includes a pedestal, and described moves in short-circuit wink
Protection buckle releaser is arranged in pedestal, and the adjusting rod hub setting is on adjusting rod axis and has in adjusting rod axis in axial sliding
Degree of freedom, and adjusting rod is pivotally supported on pedestal.
In another specific embodiment of the present invention, on the adjusting rod and back to the instruction unit
Position is extended with reaction spring fixed feet with space state, and one end of the reaction spring, which connects and is supported on reaction spring, to be consolidated
Determine on foot, and the other end connects and is supported on the armature, the adjusting rod is made axial left and right on the adjusting rod axis and is moved
Dynamic position is configured to the progressive error between adjusting rod and the armature, by the spring force of reaction spring described in the trip official post
Size generates corresponding variation.
In another specific embodiment of the present invention, the housing further includes a pedestal and one matched with pedestal
It base seat lid and one is arranged in base seat lid and in a breaker cover board of the top corresponding to the trip gear, it is described
Instruction unit probes into window and is opened on breaker cover board, the instruction unit towards the base seat lid direction extension and with instruction
Portion probes into window and is engaged.
In another specific embodiment of the present invention, in the instruction unit and positioned at the position of the end of instruction unit
Putting composition has an instruction unit card to dash forward, and is probeing on the breaker cover board and corresponding to the instruction unit long side side of window
To one side position be equipped with for disclose short-circuit instantaneous protection buckle releaser difference current regulation gear circuit breaker short circuit protect
Value mark, and instruction unit probe into the window wall for the one side that window is identified towards circuit breaker short circuit protection value and corresponding to
The instruction unit card that the location interval of circuit breaker short circuit protection value mark offers the surface for being depressed in window wall is dashed forward mating groove, works as finger
The portion card of showing dash forward with instruction unit card dash forward mating groove engage when, the instruction unit is positioned in corresponding to the circuit breaker short circuit protection value
The position of mark.
In the yet another specific embodiment of the present invention, draw bar adjusting is offered on the breaker cover board
Window, the draw bar are set on the draw bar axis, and draw bar is pivotally supported on the pedestal, and is led by described
Draw bar to adjust the adjusting of axial movement position of the window to draw bar on draw bar axis and realize and move overload thermal trip
Make the adjusting of electric current gear, the armature makees draw bar in the adjusting stroke range of the axial movement position of the draw bar
With.
In the present invention there are one in specific embodiment, set in the position of the top corresponding to the breaker cover board
Tegillum is equipped with, a tegillum instruction unit is offered in small cover and probes into window, which probes into window and the finger
The portion of showing probes into that window is corresponding, and the instruction unit, which by way of the instruction unit probes into window and is insinuated into the tegillum instruction unit, to be probeed into
