With reference to Fig. 2-6, the device operation when residual current surpasses predetermined limit value is described below.
From mode of operation shown in Figure 2, promptly tripgear is prepared to intervene, and when residual current surpassed predetermined value, pin 17 activated, and impacts the arm 3 ' of actuator rod 3, forces it to rotate along direction shown in the arrow 101 around pivot 18.
As shown in Figure 3, by the geometric match of 50 in abutment walls 51 and tooth, actuator lever 3 pulls to self with trip(ping) bar 4 simultaneously, and it is rotated along same direction, from the engaging of engaging lever 8 throw off; In this way, the remainder of mechanism 100 can move freely.Specifically, indicating arm 6 rotates along direction shown in the arrow 102 under the trying hard to recommend of actuation spring 2, by being pushed against the piece 53 on the tooth 54, is connected on the drive link 7, and it is moved along the part of rotation at least.In addition, in described rotary course, indicating arm 6 promotes contact lever 115, and by finishing a translational motion, contact lever acts on a spring, and this spring belongs to the unshowned test circuit of tripgear outside.The correct translational motion of contact lever is assisted by two guiders on the pedestal 1 116.
Then, bar 7 is passed to the dynamical system of relative breaker with motion, and its contact is opened.As shown in Figure 4, when piece 45 was resisted against on the retainer 55, the rotation of bar 6 finished.In this position, shaping end 23 is arranged at the opening part of shell, from exterior visual point out that circuit breaker intervenes because of residual current.
Advantageously, the end 2 ' of actuation spring 2 impacts shaping end 60 in its motion process, and mobile actuator lever 3 pushes against on the pin 17, as shown in Figure 4 arm 3 '.Bar 3 remains on this position, resets up to device, thereby as the reset apparatus of actuation element; In addition, if described actuation element is a polarized relay, just can avoid any dirt.In addition, by trying hard to recommend of retainer spring, trying hard to recommend of spring 40 especially, tooth 50 is resisted against on the abutment walls 51, and bar 3 and 4 returns to directly and is in contact with one another.
In these steps,, also be blocked by pivot 28 rigid attachment handle 10 thereon if the actuation handle of relative breaker is blocked; Correspondingly, actuating unit 100 remains on position shown in Figure 4, does not move and do not have further.If opposite, this situation does not occur in the aforesaid operations step, and along with the motion of relative breaker, certain delay just begins handle 10 because of its inertia has, and rotates along arrow 103 indicated directions, moves to position shown in Figure 5.Because return spring 13, handle 11 rotates along arrow 103 indicated directions, by U-shaped element 12, promotes engaging lever 8; In this way, hamulus 27 moves past projection 26, arrives position shown in Figure 5.In this position, device is prepared to reset.
In this rotary course, bar 6 is motionless substantially owing to the rigidity of relative actuation spring 2.
Provide replacement by directly acting on the actuation handle that the circuit breaker of handle 10 is passed in motion; As shown in Figure 6, handle 10 rotates along direction shown in the arrow 104, makes abutment walls 61 push against on the projection piece 62 of handle 11.In this way, handle 11 also rotates along direction shown in the arrow 104 by U-shaped element 12, and rotational engagement bar 8 abuts on the projection 26 up to hamulus 27.Along with the motion of the dynamical system of relative breaker, drive link 7 rotates along the direction of arrow 105, and the interaction by 53 of tooth 54 and pieces makes indicating arm 6 motions, makes it turn back to original position.Then, bar 6 moves contact lever 115, and loading spring 2 makes them get back to its initial position.When rotation finished, projection piece 62 was resisted against on the retainer 73, schematically illustrates as Fig. 2.
Advantageously, device is designed to reset before the relative breaker closing of contact, prepares new once intervention.In this way, can guarantee that residual current continued to surpass a predetermined safety margins value when electric current in the ifs circuit recovered, and then opened the contact immediately again.
Advantageously, if the intervention of circuit breaker is not because the existence of residual current but because of other operating conditions, for example order of sending because of a servicing unit, drive link 7 indicating arm 6 relatively rotates freely.In this case, bar 7 receives motion from servicing unit by an attachment pegs, and this attachment pegs is passed a groove 91 on the pedestal 1, and insertion rod 7 is from one's body a groove 24.In this situation, drive link 7 moves along direction shown in the arrow among Fig. 2 106, and relative breaker is passed in motion, and the remainder of actuating unit can not be subjected to the influence that this moves.In this way, residual current circuit breaker if any, is designed to the servicing unit of a reality, and its dynamical system is fully by bypass.
Tripgear according to the present invention also has another advantage, and promptly it can be connected to multipole magnetic thermal circuit beraker, and irrelevant with the layout of each utmost point, is positioned at right side or left side as neutral pole.Under this situation, be enough in fact, needn't carry out structural modification each element by what dynamical system was rotated 180 ° of assemblings.
In the practice, have found that, realized the purpose and the task that are intended to reach fully, even because it provides servicing unit when having pure residual current circuit breaker also can be positioned at the circuit breaker relevant with tripgear of both sides according to tripgear of the present invention.This device also has a kind of self-supporting modular construction, and it can be used as an autonomous block and is linked on the circuit breaker, and the simple and basic automation of its assembling.
Advantageously, She Ji tripgear except being particularly suitable for directly being linked on the magnetic thermal circuit beraker, also can be used to residual current stopper (residual currentblocks) and the pure residual current circuit breaker used always effectively like this.All the novel functions and the creationary aspect that it shall yet further be noted that this device all can obtain by using commercial available cost extremely low element and material.
