Abstract
The utility model discloses a drop-out fuse with a standby cartridge. The fuse comprises an insulator column and a cartridge arranged on the insulator column, wherein the cartridge is internally provided with melt. The fuse further comprises a standby cartridge arranged side by side with the cartridge, wherein the standby cartridge is internally provided with a standby melt. A connection post is arranged on the bottom of the standby cartridge, such that the standby cartridge can be movably connected with the standby melt. A switching structure is arranged between the cartridge and the standby cartridge. The switching structure is composed of a switching spring and a start sheet spring connected with the switching spring. One end of the switching spring is connected with the melt of the cartridge, and the other end of the switching spring is connected with the start sheet spring. The start sheet spring is interposed between the standby melt and the connection post. The drop-out fuse provided by the utility model has the advantages of simple structure, convenient use, simple installation, easy operation, high applicability and good practicality.
Description
Technical field
The utility model belongs to the fuse switch technical field, is specifically related to a kind of fuse switch with standby fusion tube.
Background technology
The outdoor high-voltage drop type fuse model of prior art is various, it generally is comprised of insulator, fuse tube, it in use, often existing mechanical breakdown or ectocine to produce mistake broke and made fuse forever to cut-off, it is not suitable for the place that power reguirements is higher to a certain extent, and the fuse switch of prior art does not have standby fuse tube yet, it needs long-time outage when maintenance, also can cause comparatively serious economic loss to a certain extent, limited to a certain extent the serviceability of fuse, practicality is poor.
Summary of the invention
The purpose of this utility model is to provide a kind of simple in structure, easy to use and fuse switch with standby fusion tube that practicality is good.
The technical scheme that realizes the utility model purpose is a kind of fuse switch with standby fusion tube, comprise the insulator pillar, be arranged on the fuse tube on described insulator pillar, be provided with melt in described fuse tube, also comprise the standby fusion tube be arranged side by side with described fuse tube, be provided with standby melt in described standby fusion tube, be provided with the joint pin be flexibly connected with described standby melt in the bottom of described standby fusion tube, be provided with transformational structure between described fuse tube and described standby fusion tube, described transformational structure comprises throw over spring, the startup shell fragment be connected with described throw over spring, one end of described throw over spring is connected with the melt of described fuse tube, the other end of described throw over spring is connected with described startup shell fragment, described startup shell fragment is arranged between described standby melt and described joint pin.
Be provided with the startup indicating lamp structure in described standby fuse tube.
During use, fuse tube is connected with standby fusion tube simultaneously, before in fuse tube, melt does not fuse, the throw over spring of transformational structure pulls the startup shell fragment, make standby fusion tube in off-state, when the melt in fuse tube fuses, pulling force disappearance due to throw over spring, throw over spring drives and starts the shell fragment startup, start shell fragment and control being connected of standby melt and joint pin, make standby fusion tube work, while continuing to connect after fuse tube is changed or keeped in repair, throw over spring resets, making to start shell fragment controls standby melt and is connected disconnection, realize standby effect, can effectively reduce the loss to a certain extent, practicality is good.
The utlity model has positive effect: of the present utility model simple in structure, convenient to use, and also simple installation, simple to operate, applicability is strong, and practicality is good.
The accompanying drawing explanation
For content of the present utility model is more likely to be clearly understood, below according to specific embodiment also by reference to the accompanying drawings, the utility model is described in further detail, wherein:
Fig. 1 is structural representation of the present utility model.
Embodiment
(embodiment 1)
Fig. 1 has shown a kind of embodiment of the present utility model, and wherein Fig. 1 is structural representation of the present utility model.
See Fig. 1, a kind of fuse switch with standby fusion tube, comprise insulator pillar 1, be arranged on the fuse tube 2 on described insulator pillar 1, be provided with melt 3 in described fuse tube 2, also comprise the standby fusion tube 4 be arranged side by side with described fuse tube 2, be provided with standby melt 5 in described standby fusion tube 4, be provided with the joint pin 6 be flexibly connected with described standby melt 5 in the bottom of described standby fusion tube 4, be provided with transformational structure 7 between described fuse tube 2 and described standby fusion tube 4, described transformational structure 7 comprises throw over spring 71, the startup shell fragment 72 be connected with described throw over spring 71, one end of described throw over spring 71 is connected with the melt 3 of described fuse tube 2, the other end of described throw over spring 71 is connected with described startup shell fragment 72, described startup shell fragment 72 is arranged between described standby melt 5 and described joint pin 6.
Be provided with the startup indicating lamp structure in described standby fuse tube 4.
During use, fuse tube is connected with standby fusion tube simultaneously, before in fuse tube, melt does not fuse, the throw over spring of transformational structure pulls the startup shell fragment, make standby fusion tube in off-state, when the melt in fuse tube fuses, pulling force disappearance due to throw over spring, throw over spring drives and starts the shell fragment startup, start shell fragment and control being connected of standby melt and joint pin, make standby fusion tube work, while continuing to connect after fuse tube is changed or keeped in repair, throw over spring resets, making to start shell fragment controls standby melt and is connected disconnection, realize standby effect, can effectively reduce the loss to a certain extent, practicality is good.
Obviously, above-described embodiment of the present utility model is only for the utility model example clearly is described, and is not the restriction to execution mode of the present utility model.For those of ordinary skill in the field, can also make other changes in different forms on the basis of the above description.Here exhaustive without also giving all execution modes.And these belong to apparent variation or the change that connotation of the present utility model extends out and still belong to protection range of the present utility model.
