Abstract
The utility model discloses a quick-connection type drop-out fuse assembly. A stay cord is driven to pull off an insulating spacer through the shedding of a second assembly, thereby enabling a fuse tube to electrically contact with a first electric-contact spring piece, and maintaining the continuous operation. The assembly is simple in structure. A high-efficiency fuse can replace a tubular fuse element, and is simply installed in a conventional insulator unit.
Description
Technical field
The utility model relates to Fuse assembly, is specifically related to one and connects soon formula drop out fuse assembly.
Background technology
Fuse is at high-voltage fence, and such as widely using in distributor point, to protect the electric equipment in electrical network to avoid system surge infringement, system surge is caused by short circuit (comprising the short circuit being caused by lightning attack) and overload conventionally.The surge of even now is normally instantaneous, such as being caused by lightning, in any case but fuse all fuse, and no matter whether instantaneous surge probably occurs very soon again.
In the case of there is no to be sequentially connected to automatically, one at a time the second fuse even the fuse base assembly of the 3rd fuse, the consumer who obtains electric energy by this particular electrical circuit will suffer power interruptions, and this may be very inconvenient, harmful and suffer heavy losses.Distribution wire extends the very long distance that is difficult to be open to traffic conventionally, and therefore location and maintenance failure can spend the long duration.What is worse, such power interruptions usually occurs in night or bad weather, or in the two situation about having concurrently.All these has extended the duration of power interruptions.
In order to help the fuse of location fusing and it to be changed, dropping type fuse assembly widely uses, and in this case, a fuse self that extends through tubulose fuse element is used to keep hinged at extended position; In the time of fuse failure, tubular fuse element comes off from its service position, and normally hangs upside down from hinged suspension, thereby is very easy to be found and is convenient to change.Elongate tool can be used to make such tubular fuse element, at least in some cases, can be stood in ground electrician and change.
For the instantaneous surge that unlikely repeats to occur, in order to resist the adverse effect of the interruption duration of following its appearance, people propose and have used various so-called repetition fuses.Such repetition fuse assembly has at least one second fuse element conventionally, also may there is the 3rd fuse element, they leave in this assembly by a kind of mechanism, in the time that the fuse of fusing loses tension force, this mechanism is triggered, by this mechanism, another fuse element is connected in interlock circuit automatically.
Fuse can be replaced the in the situation that of interrupt power supply not, but this fuse assembly is very complicated, and applicant thinks that its cost is higher.These repeat fuse assembly also such shortcoming: connect and have inappropriate time delay to another fuse from a fuse blows, this can not fully disappear the electric arc being produced by the fuse fusing.
Application number is dropping type fuse assembly and the fuse base of CN200780044396.8, a kind of fuse assembly is disclosed, this assembly connects touching the second assembly after the first assembly fusing by leaf spring, the leaf spring of this invention is in use always stressed, cartridge fuse is touched vertically, such connection is insecure, i.e. the connection of the second contact arrangement is not closely with firm.
Utility model content
Connect insecurely for cartridge fuse assembly in prior art, not closely and the technical problem such as firm, it is a kind of simple in structure that the utility model provides in the connection of contact arrangement, stable connection connect soon formula drop out fuse assembly.
To achieve these goals, the technical solution adopted in the utility model is: connect soon formula drop out fuse assembly, comprise insulated column, the first contact assembly is fixed in insulated column upper end, lower end is fixed first and is articulated cartridge fuse assembly, the first cartridge fuse contact of the first cartridge fuse upper end contacts with the first contact assembly, lower end articulates and is supported on first and articulates on cartridge fuse assembly, described the first cartridge fuse contact is fixed on the second electric shock assembly, first articulates cartridge fuse component string is associated in second and articulates cartridge fuse assembly, it is the second cartridge fuse that the second electric shock assembly and second articulates between cartridge fuse assembly, fuse in the first cartridge fuse is electrically connected with the spring leaf being fixed on the first cartridge fuse, with the first cartridge fuse contact electric insulation, on the second electric shock assembly, fix the first electric shock spring leaf with cartridge fuse spring leaf opposite position, between cartridge fuse spring leaf and the first electric shock spring leaf, clamp insulation cushion, make the two electric insulation, insulation cushion is fixed on the second cartridge fuse by insulating cord.
Beneficial effect is: the utility model is simple in structure, fuse efficiently, it can replace tubular fuse element and be arranged on simply in existing insulator unit, by coming off of the second assembly, drive stay cord to pull off insulation spacer, cartridge fuse spring leaf and the first electric shock spring leaf are electrically contacted, keep fuse continuous operation.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Embodiment
As shown in Figure 1, connect soon formula drop out fuse assembly, comprise insulated column 1, the first contact assembly 2 is fixed in insulated column 1 upper end, lower end is fixed first and is articulated cartridge fuse assembly 3, the first cartridge fuse contact 5 of the first cartridge fuse 4 upper ends contacts with the first contact assembly 2, lower end articulates and is supported on first and articulates on cartridge fuse assembly 3, described the first cartridge fuse contact 5 is fixed on the second electric shock assembly 51, first articulates cartridge fuse assembly 3 is connected on second and articulates cartridge fuse assembly 31, it is the second cartridge fuse 41 that the second electric shock assembly 51 and second articulates between cartridge fuse assembly 31, fuse in the first cartridge fuse 4 is electrically connected with the spring leaf 21 being fixed on the first cartridge fuse, with the first cartridge fuse contact 5 electric insulations, on the second electric shock assembly 51, fix the first electric shock spring leaf 52 with cartridge fuse spring leaf 52 opposite positions, between cartridge fuse spring leaf 52 and the first electric shock spring leaf 21, clamp insulation cushion 6, make the two electric insulation, insulation cushion 6 is fixed on the second cartridge fuse 41 by insulating cord 7.
By coming off of the second assembly, drive stay cord to pull off insulation spacer, cartridge fuse spring leaf and the first electric shock spring leaf are electrically contacted, keep fuse continuous operation.
