Description
Technical field
The present invention relates to Low Voltage Electrical Apparatus, more specifically to the electromagnetic protection device in device for switching.
Background technique
Electromagnetic protection device can protect overload current and short circuit current.Switch is electrical, such as the guarantor of breaker
Shield is usually controlled by electromagnetic protection device.Electromagnetic protection device is more applied to the breaker of low capacity.Rated current is high
More electronic type is used to protect in the large capcity breaker of 1000A, i.e., by the electric current in transformer induced circuit, and by controlling
Device is monitored electric current, is acted by magnetic release.In large capcity breaker of the rated current higher than 1000A, very
Electromagnetic protection device is used less.
But if being needed from market and the considerations of use cost, in the large capcity breaker of 1000A or more if
Higher cost performance can be obtained using electromagnetic protection device, thus have preferable application market.Traditional pyromagnetic
In protective device, Thermal protection component uses eddy heating for heating bimetal leaf, promotes it to generate thermal deformation, inspires by this deforming thrust
Circuit breaker operation mechanism movement.Magnetic protection component reaches snap action multiple using the counter-force and air gap of electromagnet adjustment spring can
It adjusts, and inspires operating mechanism tripping by a series of actions rod piece.The Thermal protection component of traditional electromagnetic protection device is due to adopting
With the technology of eddy-current heating, thus it is more difficult to control, and amount of parts is more, cost advantage is poor, in addition Thermal protection bimetallic
The thrust that piece deformation generates is usually smaller, for the operating mechanism of large capcity breaker, requirement that biggish tripping force, so
Bimetal leaf is difficult to push directly on mechanism tripping.Traditional magnetic protection component needs while adjustment spring counter-force and air gap, because
There are two Parameters variations for this which, it is more difficult to and design calculates and verifying, and to often result in adjusting force larger for counter spring force adjusting,
It makes troubles to user, in addition it is more to inspire system parts for magnetic protection, hardly results in ideal breaker quick acting speed.
Summary of the invention
The present invention is directed to propose the Thermal protection group a kind of novel electromagnetic protection device suitable for large capcity breaker
Part.

On busbar, the top of the longitudinal portion of L shape bimetal leaf is working face.
In one embodiment, Thermal protection component and energy storage component cooperate, when there is overload current, the touching of Thermal protection component
Energy storage component movement is sent out, energy storage component hits the operating mechanism of breaker.
In one embodiment, energy storage component is snapped in normal work, the working face of energy storage component and bimetal leaf
Between exist interval, when there is overload current, bi-metal plate deformed is contacted with energy storage component, so that energy storage component is unbuttoned and moved
Make.
In one embodiment, energy storage component includes energy storage bar, bimetallic adjusting rod and energy-stored spring.It is working normally
When, bimetallic adjusting rod is not contacted with the working face of bimetal leaf, and bimetallic adjusting rod latches mutually with energy storage bar, energy-stored spring
Energy storage.When there is overload current, bi-metal plate deformed pushes bimetallic adjusting rod to unbutton with energy storage bar, and energy-stored spring releases energy,
Drive the operating mechanism of bimetallic adjusting rod strike breaker.
In one embodiment, bimetallic adjusting rod has contact bar, when there is overload current, the work of bimetal leaf
Face and contact bar contact are to push bimetallic adjusting rod.
In one embodiment, the different location on the working face of contact bar alignment bimetal leaf, contacts bar and working face
Between interval difference to obtain different overload currents.
Thermal protection component in electromagnetic protection device of the invention triggers energy storage component by bimetal leaf and moves to complete tripping
Make, structure is simple, quick action and energy storage component is able to maintain the constant of tripping force.The working face of bimetal leaf is inclined-plane,
Different location on inclined-plane can provide the different interval between bimetal leaf and energy storage component, to obtain different overload electricity
Stream.
