III, connecting lever? the other end and the pull bar of III are hinged.On-load switch fuse combined electric apparatus overcurrent tripping mechanical device of the present utility model, use the relation of double leval jib theory of mechanics overlap joint fuse and on-load switch cleverly, make to cut-off on-load switch rapidly after any phase fuse disconnects and cut off whole circuit, avoid the situation of load operational impairment load in the circuit of phase shortage, reasonable in design, low cost of manufacture, frequency of maintenance are low, and security performance is high.
Description
Technical field
The utility model relates to high-voltage electrical apparatus field of switches, particularly relates to on-load switch fuse combined electric apparatus overcurrent tripping mechanical device.
Background technology
In high-tension switch gear field, on-load switch fuse combined electric apparatus switch cubicle uses very extensive.Its role is to when short circuit or overcurrent are broken down in load that it effectively can will carry out circuit disconnection, then being realized by dropout mechanical device for reaching such function.Striker action after fuse blows also clashes into push rod, push rod ejects immediately, but can not directly promote on-load switch separating brake, dropout mechanical device solves fuse at fusing pusher dynamic load switch separating brake, but current this dropout mechanical device design is unreasonable, in use often occur some problems, maintenance work is more, security is relatively low, there is certain hidden danger.
Utility model content
The utility model is intended to for Problems existing in background technology, and the on-load switch fuse combined electric apparatus overcurrent tripping mechanical device provided.
On-load switch fuse combined electric apparatus overcurrent tripping mechanical device of the present utility model, be made up of pressing plate, pull bar, push rod and fuse, its pressing plate and three fuse afterbodys are fixed by socket, the connecting lever I hinged with pressing plate is equipped with above the push rod of each fuse, the other end of connecting lever I is connected by connecting rod link with the drive shaft laterally installed above pressing plate, described connecting rod is articulated and connected with the connecting lever II be fixed on drive shaft, drive shaft is fixed with connecting lever III, the other end and the pull bar of connecting lever III are hinged.
As preferably of the present utility model, three fuses become inverted triangle shape to be arranged on pressing plate, for being fixed on the connecting lever III on drive shaft above the push rod of two fuses of top.
As preferably of the present utility model, connecting lever I, connecting rod, connecting lever II and pull bar form double leval jib transmission mechanism.
On-load switch fuse combined electric apparatus overcurrent tripping mechanical device of the present utility model, the installation of fuse on switch cubicle is solved by electrical equipment overcurrent tripping double leval jib mechanical device, use the relation of double leval jib theory of mechanics overlap joint fuse and on-load switch cleverly, make to cut-off on-load switch rapidly after any phase fuse disconnects and cut off whole circuit, avoid the situation of load operational impairment load in the circuit of phase shortage, reasonable in design, low cost of manufacture, frequency of maintenance are low, and security performance is high.
Accompanying drawing explanation
Fig. 1 is front view of the present utility model;
Fig. 2 is structure sectional view of the present utility model.
Detailed description of the invention
Below in conjunction with Fig. 1 and accompanying drawing 2 to on-load switch fuse combined electric apparatus overcurrent tripping mechanical device of the present utility model, elaborate.
On-load switch fuse combined electric apparatus overcurrent tripping mechanical device of the present utility model, be made up of pressing plate 1, pull bar 2, push rod 3 and fuse 4, its pressing plate 1 and three fuse 4 afterbodys are fixed by socket, the connecting lever I 5 hinged with pressing plate 1 is equipped with above the push rod 3 of each fuse 4, the drive shaft 6 laterally installed above the other end of connecting lever I 5 and pressing plate 1 is articulated and connected by connecting rod 7 chain connection, described connecting rod 7 and the connecting lever II 8 be fixed on drive shaft 6, drive shaft 6 is fixed with connecting lever III 9, the other end and the pull bar 2 of connecting lever III 9 are hinged.
Can by three fuse 4(and three-phase fuse in actual production) become inverted triangle shape to be arranged on pressing plate 1, for being fixed on the connecting lever III 9 on drive shaft 6 above the push rod 3 of two fuses 4 of top, only need installing connecting rods 7 on the push rod 3 of foot, connecting lever I 5, connecting rod 7, connecting lever II 8 and pull bar 2 form double leval jib transmission mechanism.Three-phase fuse is fixed on switch cabinet by pressing plate, during normality "on" position, the end that the front end of connecting lever I 5 is namely hinged with pull bar 7 is placed on push rod 3, when any one fuse blows, push rod 3 ejects, and then the connecting lever I 5 on top, place is promoted, quadric chain is driven to be pulled by pull bar 2, the on-load switch of pull bar 2 gauge tap cabinet.
As known by the technical knowledge, the utility model can be realized by other the embodiment not departing from its Spirit Essence or essential feature.Therefore, above-mentioned disclosed embodiment, with regard to each side, all just illustrates, is not only.Allly all to be included in the utility model within the scope of the utility model or being equal to the change in scope of the present utility model.
