Abstract
The utility model discloses a fusing linkage device of a fuse, which includes a cabinet body, force bearing pieces receiving the action of a fusing mandril on a fuse bracket, and a force transmitting piece for using the action on a tripping mechanism, wherein the force bearing pieces and the force transmitting piece are mounted on the cabinet body; all of the three force bearing pieces are connected with the cabinet body through hinge shafts respectively, the three force bearing pieces are connected mutually through the hinge shafts and connecting rods respectively, and the connecting rods are hinged on one swinging piece hinged on the cabinet body; and the force transmitting piece is rod-shaped, is erected and mounted on the cabinet body through a guide sleeve, and is pressed and connected on the swinging piece. The fusing linkage device is used for transmitting the action of the fusing mandril on the fuse bracket to the tripping mechanism; and compared with the prior art, the problems of complicated structure and low reliability in the prior art can be solved.
Description
Technical field
The utility model relates to power distribution equipment manufacturing technology field, and particularly a kind of being used in ring main unit passed to device on the tripping mechanism with the action of the fusing push rod on the fuse support.
Background technology
In existing sulfur hexafluoride gas-insulating looped network switch apparatus, particularly include in the looped network switch apparatus of fuse group, the structure that the action of the fusing push rod on the fuse support is passed to the device on the tripping mechanism is complicated, the institutional adjustment parts are many, the part workmanship requires high, thereby and easily botch routines and cause electric accident, can't guarantee reliability, the stability of entire mechanism, even can be owing to the accident that meets accident of disjunction in time, cause device damage to burn, make the ring network power supply line failure that is subjected to this ring main unit control.
Summary of the invention
The purpose of this utility model provides a kind of fuse blows linkage, and this device can solve prior art complex structure, problem that reliability is low.
In order to address the above problem, the technical scheme that this fuse blows linkage adopts is: it includes cabinet and is contained in the stressed member of the fusing push rod action of accepting on this cabinet on the fuse support and action is used for sending the power part on the tripping mechanism, in addition, described stressed member has three, and the described stressed member of each part is used to accept the action of the fusing push rod on the fuse support of a phase fuse; Each described stressed member is connected on the described cabinet by jointed shaft respectively, described these three stressed members interconnect by jointed shaft and connecting rod respectively, when making central any of three described stressed members be subjected to fusing push rod promotion, this promotion is changed into the action of connecting rod, according to this transmission principle, described connecting rod can be served as by a shaft-like part, also can be connected by many shaft-like parts and serve as, even can also be served as by one or more plate part that is linked to be; Described connecting rod is hinged on the swing component, and this swing component is hinged on the described cabinet, makes the motion of described connecting rod drive the rotation of described swing component; The described power of sending part is shaft-like, this send the power part to be erected to be contained on the described cabinet by fairlead, this send the power part to be crimped on the described swing component, under the action of gravity of the described power of sending part, making the rotation of swing component drive described stressed member moves upward and allows the described power of sending part move downward under action of gravity, when the described power of sending part moved upward, the parts that can promote on the tripping mechanism were realized threading off.
Have following beneficial effect owing to adopted such scheme, the utility model to compare with existing fuse blows linkage:
1, this apparatus structure is simple, reliable operation.
2, be active in one's movements; can guarantee that operate time that fuse fusible core bump interlock dropout protective device can control is in 50 milliseconds; when any one in the three-phase fuse fuses mutually; fuse fusible core bump interlock dropout protective device all can pass through this device drive tripping mechanism enforcement separating brake accurately, timely and thread off; make the timely disjunction of on-load switch; fault rate is lower than 1,000,000/, can prevent the misoperation of switch effectively, improve the running quality of controlled ring network power supply circuit.
Description of drawings
Accompanying drawing 1 is the structural representation of the utility model embodiment.
Embodiment
The utility model is described in further detail below in conjunction with accompanying drawing.
Fuse blows linkage shown in Figure 1 has cabinet 4, is erected to be equipped with the interlocking rod 2 that the power part is sent in conduct by fairlead 3 on the cabinet 4; Bottom at cabinet 4 is equipped with three stressed members of being made by fan-shaped sheet material 6,7,8 respectively by jointed shaft 12,13,14, three stressed members 6,7,8 are connected with a connecting rod 15 by jointed shaft respectively again, the right-hand member of connecting rod 15 is hinged on the swing component 5 by jointed shaft, swing component 5 also is to be made by fan-shaped sheet material, swing component 5 is contained on the cabinet 4 by jointed shaft, and the lower end of interlocking rod 2 in the upper end crimping of swing component 5.
This device in use, three stressed members 6,7,8 are right against the fusing push rod 9,10,11 on three fuse supports of its below respectively, the upper end of interlocking rod 2 is right against the dropout parts 1 on the tripping mechanism.When arbitrary fusing push rod in three fuses upwards endured out, with one in the middle of the promotion stressed member 6,7,8, after this central arbitrary is pushed, to drive connecting rod 15 moves right, connecting rod 15 moves right and drives swing component 5 and rotates counterclockwise, swing component 5 rotates counterclockwise just and to promote the interlocking rod 2 dropout parts 1 that upwards act on the tripping mechanism, makes the tripping mechanism action of threading off immediately, with drive ring main unit separating brake.
Claims (1)
1. fuse blows linkage, include the stressed member of the fusing push rod action that cabinet and being contained in accepts on this cabinet on the fuse support and action is used for sending the power part on the tripping mechanism, it is characterized in that: described stressed member has three, each described stressed member is connected on the described cabinet by jointed shaft respectively, described these three stressed members interconnect by jointed shaft and connecting rod respectively, described connecting rod is hinged on the swing component, and this swing component is hinged on the described cabinet; The described power of sending part is shaft-like, and this send the power part to be erected to be contained on the described cabinet by fairlead, and this send the power part to be crimped on the described swing component.
