Embodiment
A kind of embodiment of circuit breaker:
Circuit breaker comprises fishing box and is arranged on the transmission mechanism in fishing box, and the embodiment of circuit breaker is as shown in Fig. 1 ~ 5, and circuit breaker comprises 1# arc control device fracture 1, fishing box 2,2# arc control device fracture 3, pillar 4 and operating mechanism 5.Be provided with transmission mechanism in fishing box, transmission mechanism comprises: above win 601 in succession, moved end pull bar 602, transmission crank arm 603, connecting lever axle 604, under win 605 in succession, insulated tension pole jointing 606 and insulated tension pole 607.Fishing box comprises the ring flange 205 of casing 201, arc control device linkage section 202, connecting lever axle installing hole 203, pull bar linkage section 204 and arc control device linkage section 202 end face.
Two arc control device linkage sections 202 on casing are fixed on and pull bar linkage section 204 constitutes T-shaped casing in the utility model, one end of insulated tension pole is stretched in pull bar linkage section 204, and 1# arc control device and 2# arc control device are fixed on fishing box by the ring flange 205 of arc control device linkage section 202 end face.Fishing box has two connecting lever axle installing holes 203, for reducing sealing difficulty, ensure sealing effectiveness, the through hole of described connecting lever axle installing hole 203 for installing for connecting lever axle on a side box wall of fishing box, the opposite side tank wall of fishing box is for the blind hole positioned connecting lever axle that matches with above-mentioned through hole, described through hole and blind hole have identical center line, namely the circuit breaker connecting lever axle after installation only has side to penetrate casing, so the connecting lever axle be installed in connecting lever axle installing hole 203 only has one end to be in communication with the outside, only need the axle head penetrating casing 201 be sealed after parts installation in fishing box.
For convenience of the installation to connecting lever axle 604, in the utility model, two connecting lever axle installing holes 203 are opened on both sides sidewall relative on casing, in such cases every side sidewall all only has one to stretch out shaft part, avoid a certain axle head is installed, the operation such as sealing time be located at the interference of the other axle head on the sidewall of the same side; This kind of structure is also conducive to expansion connecting lever axle 604 to connect other parts simultaneously.For ensureing the synchronous of two arc control device actions, the center line of two pairs of connecting lever axle installing holes 203 is arranged in same level.
Insulation pull bar 602 one end, moved end with on win in succession 601 hinged, the other end stretches in arc control device fracture.Circuit breaker operating mechanism receive point, reclosing command motion time, the insulated tension pole hinged with operating mechanism can move up and down thereupon, move on winning in succession under the drive that moves upward of insulated tension pole 607, thus cause the lower end of left side transmission crank arm 603 to move upward, left side connecting lever 603 rotates counterclockwise along connecting lever axle 604, drives the moved end pull bar 602 of 1# arc control device to be moved to the left and drives arc control device to carry out corresponding operating; Meanwhile, right side transmission crank arm 603 can rotate clockwise along connecting lever axle 604, drives the moved end pull bar of 2# arc control device to move right, and then drives 2# arc control device to carry out corresponding operating.
Owing to having connecting lever axle installing hole 203 in the utility model on the casing 201 of fishing box, connecting lever axle is directly installed in connecting lever axle installing hole 203, the arc control device eliminated as designing to transferring power move bearing and connecting lever axle supporting base, so the number of spare parts of fishing box of the present utility model effectively less composition circuit breaker, shorten the research and development of circuit breaker, production and installation period, reduce product cost, be conducive to the market competitiveness improving circuit breaker.
In other embodiments, the arc control device linkage section of fishing box also can be other quantity identical with arc control device fracture quantity.
A kind of embodiment of circuit breaker fishing box:
In the utility model, the structure of fishing box is identical with fishing box structure in circuit breaker embodiment, repeats no more.
