Abstract
The utility model discloses a fine-tuning fuse tube for a high-voltage fuse, which comprises a fuse tube and a fuse tube that is equipped in the fuse tube. An operating ring and a moving contact are provided outside the fuse tube. A spring and a fine-tuning rotatable elastic sheet are equipped in one end of the fuse tube. An end of the fuse wire is provided with a connecting lead. The connecting lead is connected with the moving contact through the fine-tuning rotatable elastic sheet and the spring. The fine-tuning fuse tube for the high-voltage fuse has a simple structure. When the fuse wire is mounted, preliminary adjustment through the spring can be performed for preventing over-loosening. Then fine tuning is performed through the fine-tuning rotatable elastic sheet, so that the fuse wire reaches an optimal state in the fuse tube, thereby effectively preventing over-tightness or over-loosening, and improving use reliability and stability of the fuse to a certain extent.
Description
Technical field
The utility model belongs to the high-tension fuse field, is specifically related to a kind of fine adjustment type fuse tube for high-tension fuse.
Background technology
In high voltage supply; fuse switch is widely used; it mainly is made up of insulation column and fuse tube; it can reach overcurrent protection function to a certain extent; mainly be fuse is passed fuse tube and to be fixed on the electrical contact at fuse tube two ends yet the fuse switch of prior art is fuse tube; adopt this structure to have certain deficiency; because fuse is in installation process; too tight or too loose situation appears easily; and tension is broken fuse easily; may go out and can close a floodgate if cross pine, influence normal power supply, its practicality is relatively poor.
Summary of the invention
The purpose of this utility model provide a kind of simple in structure, overcome the fine adjustment type fuse tube that is used for high-tension fuse that fuse is installed too tight or too loose deficiency.
The technical scheme that realizes the utility model purpose is a kind of fine adjustment type fuse tube for high-tension fuse, comprise fuse tube and be arranged on the interior fusible link of fuse tube, the outside of described fuse tube is provided with operation ring and moving contact, be provided with spring and fine setting rotation shell fragment in one end of described fuse tube, the end of described fusible link is provided with the connection lead, and described connection lead is connected with described moving contact with spring by described fine setting rotation shell fragment.
Also comprise the adjusting knob that links to each other with described fine setting rotation shell fragment.
Described fine setting rotation shell fragment is the insulation shell fragment, and described adjusting knob is the insulation knob.
The utlity model has positive effect: of the present utility model simple in structure, when fusible link is installed, can tentatively regulate by spring, prevent that it is loose excessively, yet finely tune by fine setting rotation shell fragment again, make fusible link in fuse tube, reach optimum state, can prevent effectively that fusible link is too tight or too loose when assembling, improved dependability and the stability of fuse to a certain extent.
Description of drawings
Content of the present utility model is easier clearly to be understood in order to make, according to specific embodiment also by reference to the accompanying drawings, the utility model is described in further detail below, 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 fine adjustment type fuse tube for high-tension fuse, comprise fuse tube 1 and the fusible link 2 that is arranged in the fuse tube 1, the outside of described fuse tube 1 is provided with operation ring 3 and moving contact 4, be provided with spring 5 and fine setting rotation shell fragment 6 in one end of described fuse tube 1, the end of described fusible link 2 is provided with and connects lead 7, and described connection lead 7 is connected with described moving contact 4 with spring 5 by described fine setting rotation shell fragment 6.When fusible link is installed, can tentatively regulate by spring, prevent that it is loose excessively, yet finely tune by fine setting rotation shell fragment again, make fusible link in fuse tube, reach optimum state, can prevent effectively that fusible link is too tight or too loose when assembling, improve dependability and the stability of fuse to a certain extent.
Also comprise the adjusting knob 8 that links to each other with described fine setting rotation shell fragment 6.
Described fine setting rotation shell fragment 6 is the insulation shell fragment, and described adjusting knob 8 is the insulation knob.
Obviously, above-described embodiment of the present utility model only is for the utility model example clearly is described, and is not to be 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 need not also can't give all execution modes exhaustive.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.
