At present, existing heavy current breaker mostly is integral structure, and it is bulky, cost intensive, and can only be screwed when installing, and dismounting is complicated.
Summary of the invention
For the deficiencies in the prior art, the invention provides that a kind of volume is little, cost is low, easy-to-install large-current multiple-pole breaker.
For achieving the above object, the invention provides a kind of large-current multiple-pole breaker, comprise at least two single-pole circuit breakers of linearly arranging, the two ends of each single-pole circuit breaker respectively correspondence are provided with an input terminal and an outlet terminal, multiple input terminals on multiple single-pole circuit breaker all unification are connected on a total input-wire terminal block, described total input-wire terminal block comprises an inlet wire substrate, the side of inlet wire substrate is connected with multiple inlet wire link be linearly intervally arranged, each inlet wire link is affixed with an input terminal one_to_one corresponding, described inlet wire substrate is also equiped with a total input-wire binding post, multiple outlet terminals on multiple single-pole circuit breaker also all unification be connected on a total outlet terminal block, described total outlet terminal block comprises an outlet substrate, the side of outlet substrate is connected with multiple outlet link be linearly intervally arranged, each outlet link is affixed with an outlet terminal one_to_one corresponding, described outlet substrate is also equiped with a total outlet binding post.
The invention has the beneficial effects as follows: adopt said structure, because heavy current breaker provided by the present invention is formed by multiple single-pole circuit breaker linear mosaic, multiple input terminals on multiple single-pole circuit breaker all unification are connected on a total input-wire terminal block, multiple outlet terminals on multiple single-pole circuit breaker also all unification be connected on a total outlet terminal block, therefore the circuit breaker after combination equals multiple single-pole circuit breaker to reconsolidate into a new single-pole circuit breaker, can not only significantly promote like this can the rated current of disjunction, realize big current breaking capacity, and overall volume is significantly reduced, and effectively reduce production cost, circuit breaker overall volume reduces also to make the installation of circuit breaker more convenient simultaneously, take up room less.Separately, user also by by multiple single-pole circuit breaker independent assortment with the demand of the specified breaking current of satisfied difference, as the single-pole circuit breaker of two 200A merged the circuit breaker that just can be combined into energy disjunction 400A; The single-pole circuit breaker of three 200A is merged the circuit breaker etc. that just can be combined into energy disjunction 600A.
The bottom surface that the present invention can be set to each single-pole circuit breaker is further provided with a slippage slot, a shackle member be slidably matched with its formation is equiped with in described slippage slot, the inner end face of described shackle member in glide direction is inclined plane, the outer end both sides of described shackle member in glide direction are all connected with the elasticized flaps extended internally, the afterbody of described elasticized flaps is barb-like, and the both sides of described slippage slot correspondence arranges and can form with the barb afterbody of elasticized flaps in described shackle member the baffle plate that hook joins.
Adopt said structure, be fixedly connected with the guide rails assembling that can realize circuit breaker by described shackle member and fixed guide, can only be screwed assembling with heavy current breaker in prior art, its mounting means is more easy.During use, multiple single-pole circuit breaker is positioned on guide rail, and inwardly promotes the shackle member in its basal slip groove, the barb afterbody of elasticized flaps in shackle member is stretched out, and form hook with the baffle plate of described slippage slot both sides and join, thus circuit breaker is firmly fixed on guide rail.
The two sides that the present invention also can be set to each single-pole circuit breaker further also all offer flash barrier link slot.When many group heavy current breakers are placed into together, can on the flash barrier link slot of its adjacent monopoles circuit breaker plug-in mounting flash barrier, to improve security performance.
The present invention also can be set to the equal surface knurling of positive and negative end face of described total input-wire terminal block and total outlet terminal block further.Adding surface annular knurl on the positive and negative end face of described total input-wire terminal block and total outlet terminal block, not only makes the contact of total input-wire terminal block and input terminal and total outlet terminal block and outlet terminal more firm, but also can increase its conductive channel effect.
