Description

Rotary multichannel fuse
Technical field
The present invention relates to electric power facility field, especially, it is related to a kind of fuse.
Background technology
In electric power protection facility field, conventional protection location includes electrothermal relay and fuse；For electrothermal relay, Disconnect, and can be closed automatically after the cooling period automatically during circuit overloads；Its shortcoming be that overload response time is longer, it is necessary to treat to Ability disconnecting circuit after its bimetal leaf deformation, it is difficult to meet higher security requirement；And for current fuse, molten , it is necessary to manually change fuse or fusion tube after silk overload fusing, could restoring circuit, this will cause larger fiber crops to ordinarily resident It is tired.
The content of the invention
In view of the above-mentioned problems, it is an object of the invention to provide a kind of rotary multichannel fuse, the fuse can be in electricity Fused rapidly when passing by load, and can delay a period of time after automatic restoring circuit.
The technical solution adopted for the present invention to solve the technical problems is：The rotary multichannel fuse includes can be with clockwork spring The winder for unclamping and slowly rotating, using the winder as axis, is circumferentially evenly equipped with more than two fuses；Each fuse Two ends fixed by circular support；And end of each fuse wherein on a circular support is electrically connected to first and connect jointly Line end；The winder is provided with a contact rod radially extended, and the contact rod can be followed in the state of unfettered Winder rotates；The contact rod is pressed on a fuse by the obstruction of the fuse under the elastic force effect of winder；Institute State the second terminals that contact rod is electrically connected with the circular support.
Preferably, penetrating an electromagnet close to free end on the contact rod, and one is nested with each fuse The iron pipe that segment is not contacted with contact rod；Thus, when a fuse is blown, the free end of contact rod is gradually rotated to next Before fuse, such as occurs electric arc between fuse and contact rod, then electromagnet is switched on, and forms magnetic between the iron pipe Power, makes contact rod press to fuse rapidly, by arc extinction.Further, in the form of sheets, and sheet-like plane is parallel for the contact rod In fuse, during fast approaching fuse, significant air-flow is pushed to fuse, in favor of arc extinguishing.Further, it is described The magnetic direction of electromagnet radially so that between the end of contact rod and fuse formed electric arc when, electric arc produce deflection, with Beneficial to pulling apart electric arc.
The beneficial effects of the present invention are：The rotary multichannel fuse is serially connected in operating circuit, due to the conduction Rod and a fuse wire contacts, therefore only one fuse participation work, after the fuse for participating in work is blown, the winder Constraint is lost, is gradually rotated, until contact rod touches next fuse, during this delay, user can remove some mistakes Electrical equipment is carried, to ensure the safety of circuit, and the automatic recovery of circuit is waited.
Brief description of the drawings
Fig. 1 is the axial schematic diagram of this rotary multichannel fuse embodiment one.
Fig. 2 is the side schematic view of this rotary multichannel fuse embodiment one.
Fig. 3 is the axial schematic diagram of this rotary multichannel fuse embodiment two.
Fig. 4 is the side schematic view of this rotary multichannel fuse embodiment two.
Embodiment
The present invention is further described with reference to the accompanying drawings and examples：
Embodiment one：
In the embodiment one shown in Fig. 1, Fig. 2, the rotary multichannel fuse includes what can be unclamped and slowly rotate with clockwork spring Winder 1, the specific internal structure and clock and watch main shaft of winder 1 is essentially identical, can be directly by the suitable clock and watch main shaft structure of size Into not reinflated to repeat；It is axis with the winder 1, is circumferentially evenly equipped with 8 fuses 2；The two ends of each fuse 2 lead to Circular support 3 is crossed to fix；And end of each fuse 2 wherein on a circular support 3 is electrically connected to the first terminals jointly 41；The winder 1 is provided with the contact rod 5 that radially extends, and the contact rod 5, can be with the state of unfettered Rotated with winder 1；The contact rod 5 is pressed in a fuse by the obstruction of the fuse 2 under the elastic force effect of winder 1 On；The contact rod 5 is electrically connected with the second terminals 42 on the circular support 3.
Above-mentioned rotary multichannel fuse is serially connected in operating circuit, because the contact rod 5 only connects with a fuse 2 Touch, therefore only one fuse 2 participates in work, after the fuse for participating in work is blown, the winder 1 loses constraint, gradually Rotation, until contact rod touches next fuse, during this delay, user can remove some overload electrical equipment, to ensure The safety of circuit, and wait the automatic recovery of circuit.
Embodiment two：
In the embodiment two shown in Fig. 3, Fig. 4, from unlike embodiment one, being worn on the contact rod 5 close to free end Enter an electromagnet 6, and a bit of iron pipe 7 not contacted with contact rod 5 is nested with each fuse 2；Thus, when a fuse 2 are blown, and the free end of contact rod 5 is gradually rotated to before next fuse, such as electric arc occur between fuse 2 and contact rod 5 （Contact rod 5 it is slow close to fuse 2 when, the possibility for electric arc occur is larger）, then electromagnet 6 be switched on, and with the iron pipe 7 Between form magnetic attraction, contact rod 5 is pressed to fuse rapidly, by arc extinction.Further, the contact rod 5 in the form of sheets, And sheet-like plane is parallel to fuse 2, so that during fast approaching fuse, significant air-flow is pushed to fuse 2, in favor of going out Arc.The magnetic direction of the electromagnet 6 radially so that between the end of contact rod 5 and fuse 2 formed electric arc when, electric arc Deflection is produced, in favor of pulling apart electric arc.
The foregoing is only presently preferred embodiments of the present invention, be not intended to limit the invention, it is all the present invention spirit and Within principle, any modification for being made, equivalent substitution should be included in the scope of the protection.
