Abstract
The invention discloses a kind of breaker overcurrent instruction devices, have：Connecting plate is main circuit board；Pedestal is arranged on connecting plate；Lid covers pedestal；Scale grating is fixed on the inside of lid；Direction turning piece, near middle are hinged on scale raster center；Resetting spring, first end are fixed on direction turning piece first end, on second end nonadjustable signal grating；Indication grating is fixed in resetting spring second end；First overcurrent spring, one end is mounted on pedestal, and the first end connection of the other end and direction turning piece causes direction turning piece to generate angular displacement when circuit overcurrent by magnetic fields, displacement changes as main circuit current increases, and reduces breaker electric energy loss and breaker volume.
Description
Technical field
The present invention relates to electric system low-voltage circuit breaker protection systems technology fields, and in particular to a kind of breaker overcurrent refers to
Showing device.
Background technology
Overcurrent protection mainly includes overload protection and short-circuit protection, in Low Voltage Electrical Apparatus, breaker and electrothermal relay production
Product overload protection principle is the thermal element fever in main circuit using string, and heat is transmitted to thrermostatic bimetal-plate by heat transfer,
Make its flexural deformation, circuit breaker draw bar is pushed by deformation displacement, breaker open operation is made by transmission mechanism action, so as to real
Existing overload protection.
In the implementation of the present invention, inventor has found that the prior art has at least the following problems：Due to overload protection
It is to be realized using thermal element and bimetal leaf, in normal work, thermal element is equivalent to resistance in circuit, and electric energy can be lost,
Belong to a part for energy consumption maximum in electric system, overload protection is also low with product temperature increase requirement conflicting, and to hot double
The material specification and performance requirement of sheet metal are very high.
Invention content
The technical problems to be solved by the invention, which are to provide, a kind of reduces the disconnected of breaker electric energy loss and breaker volume
Road device overcurrent instruction device.
In order to solve the above-mentioned technical problem, the technical solution adopted in the present invention is：A kind of breaker overcurrent instruction device,
Have：
Connecting plate is main circuit board；
Pedestal is arranged on the connecting plate；
Lid, covers the pedestal；
Scale grating is fixed on the inside of lid；
Direction turning piece, near middle are hinged on the scale raster center；
Resetting spring, first end are fixed on the direction turning piece first end, and second end is fixed on the scale grating；
Indication grating is fixed in the resetting spring second end；
First overcurrent spring, one end are mounted on the pedestal, and the other end is connect with the first end of the direction turning piece.
The second overcurrent spring is additionally provided on the pedestal.
The connection back is additionally provided with increasing magnetic patch.
A technical solution in above-mentioned technical proposal has the following advantages that or advantageous effect, passes through magnetic when circuit overcurrent
Field action cause direction turning piece generate angular displacement, displacement with main circuit current increase and changes, reduce breaker electric energy loss with
Breaker volume.
Description of the drawings
Fig. 1 is the structure diagram of breaker overcurrent instruction device provided in the embodiment of the present invention；
Label in above-mentioned figure is：1st, connecting plate, 2, lid, the 3, first overcurrent spring, the 4, second overcurrent spring, 5, axis,
6th, pedestal, 7, indication grating, 8, resetting spring, 9, scale grating, 10, direction turning piece.
Specific embodiment
To make the object, technical solutions and advantages of the present invention clearer, below in conjunction with attached drawing to embodiment party of the present invention
Formula is described in further detail.
Referring to Fig. 1, a kind of breaker overcurrent instruction device has：
Connecting plate is main circuit board；
Pedestal is arranged on connecting plate；
Lid covers pedestal；
Scale grating is fixed on the inside of lid；
Direction turning piece, near middle are hinged on scale raster center；
Resetting spring, first end are fixed on direction turning piece first end, on second end nonadjustable signal grating；
Indication grating is fixed in resetting spring second end；
First overcurrent spring, one end are mounted on pedestal, the first end connection of the other end and direction turning piece.
The second overcurrent spring is additionally provided on pedestal.
Connection back is additionally provided with increasing magnetic patch.
Direction turning piece is fixed on the face of covering by axis, and when circuit breaker load side overcurrent, connecting plate, that is, main circuit generates overcurrent,
Magnetic field is generated around connecting plate, direction turning piece is rotated in an anti-clockwise direction around axis, and overcurrent spring and overcurrent spring are respectively and fixedly connected to base
The lug boss position of seat, the coefficient of elasticity of overcurrent spring is bigger than overcurrent spring, when main circuit overcurrent is not very big, direction turning piece gram
Overcurrent spring is taken, when main circuit current is even up to greatly short circuit current very much, direction turning piece overcomes overcurrent spring and overcurrent spring simultaneously
And backwards rotation.When electric current excludes over current fault, then direction turning piece is restored to normally under overcurrent spring and action of reset spring
The location of magnetic field direction turning piece.
After above-mentioned structure, when circuit overcurrent by magnetic fields cause direction turning piece generate angular displacement, displacement with
It main circuit current increase and changes, reduce breaker electric energy loss and breaker volume.
The present invention is exemplarily described above in conjunction with attached drawing, it is clear that present invention specific implementation is not by aforesaid way
Limitation, as long as employ the inventive concept and technical scheme of the present invention progress various unsubstantialities improvement or without changing
Other occasions are directly applied to by the design of the present invention and technical solution, within protection scope of the present invention.
