Description
Technical field
The present invention relates to low-voltage circuit breaker, relate in particular to a kind of frame-type low-voltage circuit breaker, the locker of specifically a kind of under voltage relay and release.
Background technology
Existing under voltage relay and release are one of important accessory of low-voltage circuit breaker, and the fault that is used for power distribution circuit voltage is lower than instructions for use is protected.Users at home and abroad no matter at present; Usually every circuit breaker all is furnished with under voltage relay and the release that the under voltage protection done is used; Its structure is an electromagnetic type, and when voltage was lower than required value, the suction that electromagnet produces reduced; Under voltage relay and release iron core discharge under the reaction spring effect, make circuit breaker tripping.But have following defective: under voltage relay and release do not switch on or situation about damaging under; Because the effect of reaction spring under voltage relay and the release iron core; Circuit breaker can not close a floodgate; If the user need be in urgent, the power supply fast in back of losing efficacy of under voltage relay and release, perhaps divide-shut brake maintenance circuit breaker easily in the case of not charged can't be real.
The purpose of a Chinese patent 200520047357.1 " a kind of emergent latching device of low-voltage circuit breaker " is through the locker of invention, prevents breaker open operation, especially when running into top vibration such as ripple, can prevent its tripping operation at the circuit breaker that uses on the warship.But the device of inventing in this patent; Having pinned the breaker open operation semiaxis, is breakneck, even circuit breaker does not also trip when protected circuit such as is short-circuited at significant trouble; Can cause fire or explosion hazard, only run into use under the extreme case on the warship.
Summary of the invention
What the present invention will solve is that the under voltage relay of prior art existence and urgent, the quick power supply after the release inefficacy can not be carried out; And the problem that can't carry out of hotline maintenance circuit-breaker switching on-off not; Aim to provide the locker of a kind of under voltage relay and release; Circuit breaker can close a floodgate fast under under voltage relay and release failure conditions, to satisfy to user's emergency service problem; Solve the user simultaneously and easily circuit breaker is carried out the divide-shut brake maintenance in the case of not charged.
For addressing the above problem; The present invention adopts following technical scheme: the locker of a kind of under voltage relay and release; Comprise support, lever and top board, it is characterized in that described lever shaft is connected on the support, and can rotate around the axis; Snap close of an end suit of lever, the other end insert in the hole on the top board and cooperate with the formation of top board upper end; Described top board is arranged on the support, and can move up and down along support, and the bottom of said top board and under voltage relay are connected with moving iron core on the release; Described snap close has a panel with circuit breaker and forms the buckling surface that locks.
Usually, under voltage relay and release are installed on the circuit breaker, and the semiaxis that the moving iron core of under voltage relay and release can promote on the operating mechanism of said circuit breaker makes operating mechanism produce tripping operation.Locker of the present invention is installed under voltage relay and the release, to pressing down, the axle of lever on support is rotated with external force a end that lever is outside; The other end of lever upwarps, and promote described top board and move upward, and then the iron core of promotion under voltage relay and release also moves upward; After moving to said lever and can not rotating; Use outer force urges snap close again, make this snap close, snap in the respective aperture of circuit breaker panel and lock along lever motion.
When needs release under voltage locking device, depress an end of lever with external force, lever is rotated around support; Simultaneously snap close is moved to the direction away from top board along lever; Snap close is withdrawed from from the respective aperture of circuit breaker panel, remove the external force that acts on lever again, then top board moves downward; The iron core of under voltage relay and release moves downward thereupon, and circuit breaker can close a floodgate again fast.
As further improvement of the present invention, the other end of described lever inserts in the hole on the top board and cooperates with described top board formation.
Further improve as of the present invention again, offer gathering sill longitudinally on the described top board, described support is provided with pivot pin, and described pivot pin inserts in the described gathering sill.Described pivot pin is two, is arranged on up and down in the described gathering sill.

Embodiment
With reference to Fig. 1, under voltage relay and release 1 are installed on the operating mechanism 2 of circuit breaker, and the moving iron core 1a of said under voltage relay and release 1 can promote the semiaxis 2a on the operating mechanism 2 of said circuit breaker.Among the figure, locker of the present invention is not installed as yet.
With reference to Fig. 2; The locker of under voltage relay of the present invention and release; Comprise support 4, lever 6 and top board 3, described lever 6 is coupling on support 4, and can rotate around axle 13; The hole 11 interior and described top boards formation that snap close 5 of an end 61 suits of lever 6, the other end 62 insert top board 3 upper ends cooperate.Offer gathering sill 10 longitudinally on the described top board 3, described support 4 is provided with up and down two pivot pins 9, and described pivot pin 9 inserts in the described gathering sill 10, and like this, top board 3 just can be along pivot pin flexible motion about in the of 9; The bottom of said top board 3 offers porose 12.Described snap close 5 has a panel 7 with circuit breaker 14 and forms the buckling surface 8 that locks.
With reference to Fig. 3, locker of the present invention is installed on the operating mechanism 2 of circuit breaker.Specifically; Support 4 of the present invention is fixed on the operating mechanism 2 of circuit breaker; Under voltage relay and release 1 also are installed in corresponding position on the operating mechanism 2 of circuit breaker, and the hole 12 of top board 3 bottoms is enclosed within and makes itself and moving iron core 1a interlock on the moving iron core 1a under voltage relay and the release 1.
With reference to Fig. 4, when needs locking under voltage relay and release, depress an end 61 of lever 6 with external force; Lever 6 is rotated around axle 13, and the other end 62 promotion top boards 3 of lever 6 move upward simultaneously, and then any proper site of the iron core 1a of promotion under voltage relay and release 1 moves upward it; After moving to extreme position; Snap close 5 is moved to top board 3 directions along lever 6 again, and snap close 5 is snapped in the respective aperture of circuit breaker panel 7, the buckling surface 8 on the snap close 5 interlocks with panel 7 inboards; Can avoid causing this device automatic unlocking owing to the external force that promotes snap close 5 removes, the state after the locking is as shown in Figure 5.
With reference to Fig. 5, when needs release under voltage locking device, depress an end 61 of lever 6 with external force; Lever 6 is rotated around axle 13; Simultaneously snap close 5 is moved to the direction away from top board 3 along lever 6, snap close 5 is withdrawed from from the respective aperture of circuit breaker panel 7, remove the external force that acts on lever 6 again; Then top board 3 moves downward, and the iron core 1a of under voltage relay and release 1 moves downward thereupon.Under voltage relay and release 1 release, circuit breaker can close a floodgate again fast.
What should be understood that is: the foregoing description is just to explanation of the present invention, rather than limitation of the present invention, and any innovation and creation that do not exceed in the connotation scope of the present invention all fall within protection scope of the present invention.
