Abstract
The utility model discloses a double power supply interlocking type circuit breaker, consisting of two groups of circuit breakers, between which an interlocking rod and a special connecting rod are added so as to form a combination and are fixedly installed by adopting face plate screws. A long hook and a short hook of the interlocking rod are respectively hooked with the connecting rod and a lockcatch of a right circuit breaker and a left circuit breaker; and the interlocking rod is made of a stainless steel material. The double power supply interlocking type circuit breaker can carry out effective switching and interlocking between double power supplies, indicate working state obviously, and better meet special requirements in the industry by adopting an installing and wiring mode of apanel structure.
Description
Technical field
The utility model relates to a kind of circuit breaker, specifically a kind of duplicate supply interlock type circuit breaker.
Background technology
Present circuit breaker all has only the function of synchronous disjunction, arriving along with industrialization and information age, the use of circuit breaker more and more widely, but because the limitation of product, can not satisfy the instructions for use of specific environment, particularly for the conversion and control this respect of duplicate supply, circuit breaker does not in the past just reach this requirement at all, and the circuit breaker of this respect is installed in again on the control panel mostly, and mounting means has in the past brought a lot of inconvenience for concrete installation.
The utility model content
(1) technical problem that will solve
Technical problem to be solved of the present utility model is promptly to realize more such problems of duplicate supply conversion and interlocking and control circuit breaker installation inconvenience at the defective of prior art, duplicate supply interlock type circuit breaker is provided, the utility model not only can solve the problem of duplicate supply conversion with the interlocking of circuit breaker, and can effectively solve the problem that circuit breaker is used in installation question on the control panel and some other protection and secure context.
(2) technical scheme
The technical scheme that its technical problem that solves the utility model adopts is: a kind of duplicate supply interlock type circuit breaker, form by two groups of circuit breakers, the middle blocking lever that adds, special connecting rod, form a combination, can between duplicate supply, effectively change and interlocking, and the operating state of circuit breaker clearly can be indicated, adopt the panel screw fixed installation.
Adding the blocking lever that stainless steel is made, the length of blocking lever in the middle of two groups of circuit breakers. short hook hooks the connecting rod and the snap close of the right and left side circuit breaker respectively, comes duplicate supply is changed and interlocking via the switch to handle.
In circuit breaker, to put into a pair of red via having of particular design. the connecting rod of green indication, the switch along with handle just can the operating state circuit breaker show on the indicator board of circuit breaker like this.
Shell imbeds four pieces of nuts through special design in the front of circuit breaker, only needed when mounted with four pieces of screw just.
(3) beneficial effect
Duplicate supply interlock type circuit breaker of the present utility model is compared with prior art, has following beneficial effect:
Can between duplicate supply, effectively change and interlocking, the indication of open-and-shut operating state can be arranged, adopt the installation and the mode of connection of panel construction, can better satisfy the specific (special) requirements of industry.

Embodiment
Next explain below with reference to Figure of description duplicate supply interlock type circuit breaker of the present utility model being done.
Duplicate supply interlock type circuit breaker of the present utility model is made up of two groups of circuit breakers, adds blocking lever and connecting rod in the middle of two groups of circuit breakers, adopts the panel screw fixed installation to form a combination.The long and short hook of described blocking lever hooks the connecting rod and the snap close of the right and left side circuit breaker respectively; Described blocking lever is a stainless steel.In circuit breaker, put into a pair of connecting rod red, green indication that has.Imbed four pieces of nuts in the front of circuit breaker.
In the interlock groove of two groups of circuit breakers, add a mechanical interlocking bar, blocking lever is placed in the interlock groove, length is arranged on the blocking lever. short two hooks, short hook stretches into the snap close place of left side circuit breaker and hooks snap close, long hook stretches into the connecting rod place of the right circuit breaker and hooks connecting rod, when circuit breaker need be by left road power supply during to the right wing power source conversion, motion drive operating mechanism motion because of the right wing circuit breaker handle, and the snap close of the moving left side of the short hook strip circuit breaker of blocking lever is threaded off, thereby make the circuit breaker disconnection on the left side and allow the circuit breaker on the right enter operating state.Because the length of gangbar. the distance between the short hook is certain, when the circuit breaker on the right is worked, the short hook of blocking lever makes the snap close of the circuit breaker on the left side be in the state of dropout always, so the circuit breaker on the left side just can not close again, like this with regard to the effective problem of having controlled the interlocking and the conversion of two power supplys.When need then being disconnected the circuit breaker of right wing during the power source conversion of road left by the right wing power supply, just can close in left road.This product has specially increased red when the design connecting rod. and green indication, the folding along with circuit breaker can indicate the operating state of circuit breaker like this, has reduced potential safety hazard.The utility model also is embedded in terminal block in the shell groove when design, has so also just improved the fail safe of protection greatly.The utility model also in conjunction with the characteristics of some industries, has also carried out new design for the mounting means and the mode of connection of product, makes product more can adapt to the characteristics of industry, has more hommization.
The above embodiment is a kind of of the more preferably concrete execution mode of the utility model, and common variation that those skilled in the art carries out in the technical solutions of the utility model scope and replacement all should be included in the protection range of the present utility model.
