Abstract
The present invention discloses a kind of direct-driven gas blow tripping device of breaker, for realizing quick acting switching-off when circuit breaker short circuit, comprise the air-blowing passage of the semi-open-type housing of arc extinguish chamber side be arranged in each phase of circuit breaker, air-blowing passage in each phase described is isolated by dividing plate, form passage independent, closed separately, each air-blowing passway place correspondence described is provided with cover plate, and one end of described cover plate closely abuts on air-blowing passway, the snap close of other end connecting breaker tripping mechanism.Above-mentioned direct-driven gas blow tripping device of breaker is when circuit breaker short circuit, gas in arc control device is free also rapid expansion fast, by air-blowing passage, sickleshaped cover plate is backed down, the motion of sickleshaped cover plate drives the snap close resolving road device tripping mechanism to make it trip, breaker open operation.Not only structure is simple, is convenient to assembling, and realizes circuit breaker quick acting switching-off, thus improves the breaking capacity of circuit breaker.
Description
Technical field
The present invention relates to a kind of tripping device for circuit breaker, particularly relate to a kind of direct-driven gas blow tripping device of breaker.
Background technology
At present, in circuit breaker design process, the breaking speed how improving breaker mechanism is directly connected to the disjunction index of circuit breaker, in the research and design improving circuit breaker breaking speed, cause the pressure of expanding gas in arc control device to drive air blowing device design concept and the manufacturing technology of the tripping mechanism of circuit breaker by means of the energy producing electric arc between contact during circuit breaker disjunction, obtain in the product and apply and prove that to the raising of circuit breaker disjunction index be effective, but the design how optimizing air blowing device makes it air-blowing and becomes the problem being more efficiently still air blowing device.Traditional circuit breaker air-blowing tripping device adopts piston type type of drive to realize threading off, and there is complex structure, assembles loaded down with trivial details, the shortcoming that breaking speed is slow and breaking capacity is poor.
Summary of the invention
The object of the present invention is to provide a kind of direct-driven gas blow tripping device of breaker, it is simple that it has structure, is convenient to assembling, can realize circuit breaker quick acting switching-off and improve the breaking capacity feature of circuit breaker.
The object of the invention is to be achieved through the following technical solutions:
A kind of direct-driven gas blow tripping device of breaker, it comprises the air-blowing passage of the semi-open-type housing of arc extinguish chamber side be arranged in each phase of circuit breaker, air-blowing passage in each phase described is isolated by dividing plate, form passage independent, closed separately, and each air-blowing passway place correspondence is provided with cover plate, one end of described cover plate abuts on air-blowing passway, the snap close of other end connecting breaker tripping mechanism.
Especially, the internal diameter of described air-blowing passage reduces from bottom to top successively.
Especially, described cover plate is sickleshaped structure, and its one end is closely posted by air-blowing passway, and the other end offers installing hole, is fixed on draw bar by installing hole by cover plate, the snap close of described draw bar connecting breaker tripping mechanism.
Beneficial effect of the present invention is, the sickleshaped cover plate of described direct-driven gas blow tripping device of breaker is directly connected with the snap close of breaker tripping mechanism and without any intermediate link, under the condition of normal operation of circuit breaker, because the snap close of breaker tripping mechanism is in buckle position, at this moment the below of sickleshaped cover plate is blocked the air-blowing passway of the side of semi-open-type housing of arc extinguish chamber just, when short circuit current fault occurs, gas in arc control device is free also rapid expansion fast, the gas expanded is produced pressure and by low wide and up narrow air-blowing passage, the sickleshaped cover plate be enclosed on passway is backed down, the motion of sickleshaped cover plate drives the snap close resolving road device tripping mechanism to make it trip, the snap close of breaker tripping mechanism is once trip, circuit breaker is with regard to quick acting switching-off.Not only structure is simple, is convenient to assembling, and realizes circuit breaker quick acting switching-off, thus improves the breaking capacity of circuit breaker.

Embodiment
Please refer to shown in Fig. 1 and Fig. 2, Fig. 1 is the profile of direct-driven gas blow tripping device of breaker of the present invention; Fig. 2 is the three-dimensional structure diagram of direct-driven gas blow tripping device of breaker of the present invention.
In the present embodiment, a kind of direct-driven gas blow tripping device of breaker it comprise the air-blowing passage 2 of semi-open-type housing of arc extinguish chamber 1 side be arranged in each phase of circuit breaker, air-blowing passage 2 in each phase described is isolated by dividing plate 8, formed independent separately, the passage closed, to ensure the short circuit accident that the effect of air-blowing may cause with difference alternate free gas, and each air-blowing passway 3 place correspondence is provided with cover plate 4, described cover plate 4 is sickleshaped structure, its one end is closely posted by air-blowing passway 3, the other end offers installing hole 5, by installing hole 5, cover plate 4 is fixed on draw bar 6, the snap close of described draw bar 6 connecting breaker tripping mechanism 7.
In order to further ensure air-blowing effect, the internal diameter of described air-blowing passage 2 reduces successively from bottom to air-blowing passway 3, thus makes the expanding gas in air-blowing passage 2 produce larger thrust to cover plate 4.
Above-mentioned direct-driven gas blow tripping device of breaker is under the condition of normal operation of circuit breaker, because the snap close of breaker tripping mechanism is in buckle position, at this moment the below of sickleshaped cover plate 4 is blocked the air-blowing passway 3 of the side of semi-open-type housing of arc extinguish chamber 1 just, when circuit breaker at disjunction short circuit current time, the energy that electric arc is huge makes the gas in arc control device free fast and rapid expansion, the gas expanded is backed down by low wide and up narrow air-blowing passage 3 the sickleshaped cover plate 4 be enclosed on passway, the motion of sickleshaped cover plate 4 drives the snap close resolving road device tripping mechanism 7 to make it trip, the snap close of breaker tripping mechanism 7 is once trip, circuit breaker is with regard to quick acting switching-off, thus realize circuit breaker quick acting switching-off, thus improve the breaking capacity of circuit breaker.
