Description
Technical field
The present invention relates to a kind of buckle releasers of breaker.
Background technique
Breaker is the common components of electric field, for connection and breaking current, and in the case where overload or short circuit
Protection is provided to route.Breaker usually has buckle releaser, disconnect breaker.
Fig. 1 show the schematic diagram of existing buckle releaser, and Fig. 2 and Fig. 3 are respectively the breaker for including existing buckle releaser
Perspective view and top view.Buckle releaser includes shell 1, switching switch 2 and electronic type tripping mechanism 3, has conducting end in shell
Son.As shown in Fig. 2, the two sides of breaker connect three groups of conductive terminals 4, it is formed with circuit in each group of conductive terminal, switching is opened
It closes and rotatable is connected to shell.
Breaker can carry out the realization of the ON, OFF, three kinds of states of threading off of product according to the structure and function of itself；ON table
Show that product connects the state in circuit；OFF indicates that product disconnects the state in circuit；Tripping expression product is in OFF state, artificially manually
State after making product thread off, or circuit appearance is overloaded, the product after short trouble is automatically cut off in product OFF state
State behind circuit.At product ON or OFF state, all it is the rotation by switching switch on shell, makes circuit breaker
It realizes product trip status, carrys out every defencive function of protective breaker product.
Concrete operations are as follows:
Conductive terminal is for connecting load circuit in breaker normal use in Fig. 3, that is, connects the every of two sides
One group of conductive terminal is separately connected circuit breaker, under normal circumstances there is stable electric current to be respectively turned on.When not going out in circuit
Now when overload, short trouble, the hook on electronic type tripping mechanism is in reset state, does not touch switching switch.
When occurring overload, short trouble in circuit, the electric current for flowing through conductive terminal will appear unexpected variation, and electric current is mutual
Sensor 6 can be transferred to PCB component 5 by sensing this curent change and being converted to signal, and PCB component 5 is by calculating and sentencing
It is disconnected, then signal is transferred to by conducting wire by electronic type tripping mechanism 3, electronic type tripping mechanism 3 can work at once, and make electronic type
Hook 7 on tripping mechanism 3 moves to trip status from reset state, and hook 7 drives switching switch 2 to rotate, realizes breaker
Tripping realize the function of protective loop and equipment thus the power supply of cut-off loop and equipment.
In the prior art, when occurring overload, short trouble in circuit, current transformer senses curent change to finally
During making de- mouth cell operation driving switching switch rotary, the calculating of the transmission by two signals, signal is needed
Judgement and the movement of two parts, the cumulative time of these normal workflows is longer, that is to say, that from failure occur to
Disengagement failure circuit, needs long time.When there is overload fault, by electronic type tripping mechanism cut-off loop electric current, press
Allow to have a suitable response time according to IEC/GB standard, meets the requirement of product standard.But there is the short of extreme currents
When the failure of road, especially when very big short circuit current occurs for circuit or equipment, need electronic type tripping mechanism very fast
Disjunction fault loop.However, the response time of existing buckle releaser is longer, can not preferably protective loop and equipment use peace
Entirely, it is difficult to meet the requirement of product standard.
Therefore, it is necessary to a kind of buckle releaser and breakers, can quickly make in the short trouble for extreme currents occur
Reaction, and cut-off loop meet the requirement of product standard so that better protective loop and equipment are using safe.

This, in the rotary course of the second magnet unit 32, the second actuation portion 322 drives the pushing part 321 of upper end to move, so that pushing
The corresponding switching switch 20 of 321 Fast Collision of portion rotates it rapidly to the second position, and circuit breaker is threaded off and cut immediately
Disconnected loop fault electric current.
In addition, in one embodiment, buckle releaser may also include at least one electronic type tripping mechanism 40, it is located at shell 10
It is interior and corresponding with circuit, as shown in figure 8, electronic type tripping mechanism 40 includes control unit (not shown), operating member 41 and electric current
Mutual inductor, when each circuit does not occur short circuit and overload, operating member 41 is in reset position, and switching switch 20 is in first
It sets, each circuit is in the conductive state.When any circuit occur short circuit when, current transformer incude the curent change in the circuit and to
Control unit sends signal, and control unit moves to trip positions according to the signal control action portion 41, so that the drive of operating member 41 is cut
It changes switch 20 and is in the second position, the circuit that short circuit occurs is cut off.
Above-mentioned electronic type tripping mechanism 40 can be existing structure, such as the structure that background of invention is recorded.Wherein, it moves
Making portion 41 can be hook portion, when short circuit occurs for any circuit, a side contacts of hook portion and switching switch 20, and switching is switched
20 are pulled to the second position.
When short circuit occurs for any circuit, corresponding electromagnetic releaser mechanism 30 is acted prior to electronic type tripping mechanism 40.
Specific: when short circuit occurs for any circuit, electromagnetic releaser mechanism 30 is first reacted and is acted, so that switching switch 20 moves,
Cut-off loop fault current.After the power-off of circuit, the second magnet unit 32 resets to original state.Simultaneously, when any circuit is sent out
When raw short circuit, electronic type tripping mechanism 40 is also acted, and switching 20 operated section 41 of switch is maintained in the second position, from
And it also can be realized tripping function.Therefore, electronic type tripping mechanism 40 can be worked independently from each other with electromagnetic release and not done mutually
It relates to, is able to drive switching switch 20 and moves, realize tripping.Electromagnetic release is more less than the part of electronic type tripping driving,
And the speed responded is faster, so the rapid disjunction circuit of energy, therefore can be used as original 40 function of electronic type tripping mechanism
Supplement and raising, and play duplicate protection, compensating for electronic type tripping mechanism 40 can not be fast when encountering bigger short circuit current
The drawbacks of fast disjunction circuit, plays the performance requirement of limiting short-circuit current.
In conclusion electromagnetic release of the invention is acted directly on switching switch by electromagnetic force, realize rapid
The function in disjunction circuit, entire reaction, action process can be completed in a very short period of time.Compared with prior art, of the invention
The reaction time is greatly shortened, improves product interrupting performance by reducing the time of short circuit breaking, compensates for electronic type tripping
Mechanism when encountering big short circuit current can not rapidly disjunction circuit the drawbacks of, quickly and effectively reach the property of limiting short-circuit current
Can require, thus preferably protective loop and equipment using safe, meet the requirement of product standard.
