Description
Technical field
The present invention relates to low voltage electrical apparatus technology field, be specifically related to a kind of small-sized electric leakage indicating mechanism and
Plant chopper.
Background technology
Now, along with the fast development of power industry, low-voltage electrical apparatus is widely used in each of national economy
In individual industry.RCCB, as a part indispensable in low-voltage electrical apparatus, plays in circuit
The defencive functions such as electric leakage, short circuit, overload, frequently use in China's home dwelling electric power system, by
Strong in the safety consciousness of user own and can not the electrical hazard that causes of timely and effective handling failure, and
RCCB uses as infrequently the dividing of circuit, closing operation conversion under normal circumstances, and itself is only
Having opening and closing state, do not leak electricity instruction or display, user does not knows that RCCB is up
Damage, it is impossible to distinguish malfunction and the reason of circuit breaker trip, thus there is safety
Hidden danger does not reaches the initial purpose of electic protection.
Chinese patent CN201663126U discloses a kind of electric leakage indicating mechanism, comprising: indicator board and
Plate, under leakage condition, electrical leakage tripping device action, drive plate to rotate, during this, plate
End can promote the left side baffle plate below indicator board, thus drives indicator board to slide to the left；Resetted
Journey is contrary with said process, the right-hand apron below the end indicator board to be promoted of plate, drives instruction
Plate slides to the right.There is following defect in this electric leakage indicating mechanism: 1, electrical leakage tripping device action rear-guard
Dynamic plate rotates, then drives indicator board to slide by plate, just can complete cutting of indicator board instruction content
Changing, the repeatedly transmission of power makes the degree of reliability of mechanism decline；On the other hand, rotating manner is relied on
During driving indicator board to slide, owing to frictional force effect causes energy loss relatively big, especially long-pending
After there is groove in ash or life-time service surface of shell, the easy clamping stagnation of indicator board, cause indicating disabler；
2, it is slidably arranged on Shell of circuit breaker due to indicator board, therefore needs to add on the housing of chopper
Work goes out the chute slided for indicator board, adds the difficulty of processing and manufacturing and assembling.

As shown in Figures 2 and 3, in the present embodiment, described electrical leakage tripping device 7 includes that electric leakage is de-
Fastening wire circle and dynamic iron core, when chopper generation leak current fault, described electrical leakage tripping device action,
Send action by iron core dynamic in electric leakage tripping coil and promote described indication piece 1 61 works around the shaft counterclockwise
Rotate；Described operating mechanism action is triggered after the most described leaky operation mechanism action, circuit breaker trip,
The moving contact component of described operating mechanism separates with static contact, the moving contact component described in moving process
Middle moving contact supporter 41 moves and unclamps retainer 2, and described retainer 2 is at the active force of back-moving spring
Under turn clockwise around rotary shaft, described retainer 2 and indication piece 1 form stop in rotation process
Coordinating, double-colored face 13 on the indication piece in window of pinning indicates leakage condition, can clearly differentiate this
Circuit breaker trip reason causes because of leak current fault；After getting rid of leak current fault, breaker closing,
Handle pushes closing position, and described operating mechanism moving contact component action contacts with static contact, is moved through
Cheng Zhong, in described moving contact component, contact supporter 41 props up retainer 2, make described retainer 2 around
Rotary shaft is made to rotate counterclockwise, and releases the detent fit relation with described indication piece 1, now, institute
State indication piece 1 61 to turn clockwise around the shaft under the active force of back-moving spring, drive indication piece 1
Upper double-colored index plane 13 swings the non-electric leakage instruction state of recovery in indication window.By two kinds of operation sides
Formula, simple realization electric leakage instruction function, mechanical engagement also improves the susceptiveness of triggering, transmission
Superior performance, it is possible to making the differentiation malfunction that user is simple and clear, using effect becomes apparent from.
Known to the figures above, electric leakage indicating mechanism of the present utility model ought only occur by leak current fault
Time, leakage tripping device single movement, in conjunction with L pole operating mechanism 4 and described N pole operating mechanism 5 it
Between be provided with gangbar, described L pole operating mechanism 4 by described gangbar drive described N pole operate
Mechanism 5 links the set-up mode of divide-shut brake, the indication piece 1 being connected in indicating mechanism and retainer 2
Detent fit, utilize while making circuit breaker trip disconnect L pole and N polar curve road described in instruction machine
Structure realizes electric leakage instruction.
When having short circuit and overload fault occurs, chopper also can trip, N pole operating mechanism 5 and L pole
Operating mechanism 4 is threaded off and is unlocked, but electric leakage indicating mechanism action i.e. will not will not realize electric leakage instruction.
Obviously, above-described embodiment is only for clearly demonstrating example, and not to embodiment party
The restriction of formula.For those of ordinary skill in the field, the most also may be used
To make other changes in different forms.Here without also all of embodiment being given
With exhaustive.And the obvious change thus extended out or variation are created still in this utility model
Protection domain among.
