Description
Technical field
The invention belongs to circuit-breaker technical field, be specifically related to the trip gear of a kind of low-pressure plastic shell circuit breaker.
Background technology
Above mentioned trip gear refers mainly to thermal release device, and more precisely, (industry is also to refer to thermal magnetic trip gear
Custom is called " Pyromagnetic release ").The version of thermal magnetic trip gear mainly has two kinds: one to be by metal fever element structure
The overload long delay protection trip gear become；Two is the short-circuit protection wink ejector half trip gear of electric magnet form.When electricity being detected
During abnormal current in road, trip gear action also activates circuit breaker tripping, cuts off circuit.Additionally, according to the electric current of chopper
Setting valve whether adjustable, generally can be divided into fixed pattern and adjustable two kinds.
For the thermal magnetic adjustable tripping device in prior art, generally individually by the regulation of rotary dial-up is carried
It is adjustable that dynamic draw bar and using embodies rated current gear.Knot due to the thermal magnetic adjustable tripping device in prior art
The position of the aforementioned rotary dial-up of structure system is positioned at the top of draw bar, thus can occupy the short transverse of trip gear undoubtedly
Space, i.e. take the height dimension of trip gear, additionally, the trip gear of this adjusting knob version is in chopper
Portion has additional space to coordinate requirement.Also, the wink in known pyromagnetic adjustable type dropout technology move and typically can be held in the mouth by regulation
The reaction spring of ferrum realizes the regulation of different electric current gear, and the active force of reaction spring with in claimed circuit
Prospective current matches, and specifically, is to be protected by the cooperation between setting current, magnetic field force and this three of counter spring force
The relation of protecting determines.Use by using rotational structure form to realize the cooperation between parts and meet reaction spring pretension
It is blanket that the regulation of power requires, but requires to exist undoubtedly to the cooperation of helicoid by moving adjustment structure rotational structure wink
It is cumbersome (being i.e. inconvenient for) in design and manufacture, because helicoid is difficult to self-locking under stress situation,
And unavoidably produce rotation because of stress, then short-circuit protection characteristic will certainly be produced impact.In view of this, adjustable type structure is eliminated
The aforementioned unfavorable factor existing for trip gear for promote short-circuit protection characteristic there is positive effect, described below
Technical scheme produces under this background.
