Abstract
A kind of novel closed-type fuse, it relates to fuse technologies field; Binding post cross-under is in insulation water-resisting mask, and insulate water-resisting mask and high-strength insulator interference fit, and the top of high-strength insulator inside is respectively arranged with moving contact, upper static contact, inner wall insulation pipe, insulation arc-extinguishing tube, double fluid fusing insurance; Upper static contact and upper moving contact adopt slide block to be connected, the bottom of high-strength insulator inside is respectively arranged with lower moving contact, the fixing card of contact, the fixing card of lower fixed contact, bolt, fusion tube lower spring, insulation and obturation cover, lower spring, fuse fixing support, and lower fixed contact and lower moving contact adopt spring to be connected; It effectively reduces the damage to operational outfit, fixed, easy to use, easy and simple to handle, increases the service life; It forms a closed environment by high-strength insulator and insulation water-resisting mask and insulation and obturation cover.Fuse built-in system is normally run, not by external environment variable effect, makes the operation of protected cut-out more reliable and stable.
Description
Technical field:
The utility model relates to fuse technologies field, is specifically related to a kind of novel closed-type fuse.
Background technology:
Fuse (fuse) refers to when electric current exceedes setting, with the heat that itself produces, melt is fused, a kind of electrical equipment of open circuit.Fuse is after exceeding setting a period of time according to electric current, makes Melt molten, thus circuit is disconnected with the heat that himself produces; Use a kind of current protector that this principle is made.Fuse is widely used in high and low voltage electric distribution system and control system and power consumption equipment, as the protector of short circuit and overcurrent, is apply one of the most general protection device.Existing fuse is short for useful life, and inconvenient operation, uses inconvenience.
Utility model content:
The purpose of this utility model is to provide a kind of novel closed-type fuse, and it effectively reduces the damage to operational outfit, fixed, easy to use, easy and simple to handle, increases the service life.
In order to solve the problem existing for background technology, the utility model adopts following technical scheme: it comprises binding post, insulation water-resisting mask, upper moving contact, high-strength insulator, upper static contact, insulation arc-extinguishing tube, double fluid fusing insurance, the fixing card of inner wall insulation pipe, lower moving contact, contact, the fixing card of lower fixed contact, bolt, fusion tube lower spring, insulation and obturation cover, lower spring, fuse fixing support; Binding post cross-under is in insulation water-resisting mask, and insulate water-resisting mask and high-strength insulator interference fit, and the top of high-strength insulator inside is respectively arranged with moving contact, upper static contact, inner wall insulation pipe, insulation arc-extinguishing tube, double fluid fusing insurance; Upper static contact and upper moving contact adopt slide block to be connected, the bottom of high-strength insulator inside is respectively arranged with lower moving contact, the fixing card of contact, the fixing card of lower fixed contact, bolt, fusion tube lower spring, insulation and obturation cover, lower spring, fuse fixing support, and lower fixed contact and lower moving contact adopt spring to be connected.
The utility model is when double fluid fusing insurance disconnects, and the slide block that upper static contact and upper moving contact adopt connects, and effectively reduces the damage to operational outfit.
The utility model has following beneficial effect: effectively reduce the damage to operational outfit, fixed, easy to use, easy and simple to handle, increases the service life.
Accompanying drawing illustrates:
Fig. 1 is structural representation of the present utility model;
Fig. 2 is the upward view of Fig. 1.
Embodiment:
Referring to Fig. 1-Fig. 2, this embodiment adopts following technical scheme: it comprises binding post 1, insulation water-resisting mask 2, upper moving contact 3, high-strength insulator 4, upper static contact 5, insulation arc-extinguishing tube 6, double fluid fusing insurance 7, inner wall insulation pipe 8, lower moving contact 9, contact fix card 10, lower fixed contact 11, bolt 12, fusion tube lower spring 13, insulation and obturation cover 14, lower spring fix card 15, fuse fixing support 16; Binding post 1 cross-under is in insulation water-resisting mask 2, and insulation water-resisting mask 2 and high-strength insulator 4 interference fit, make two parts reach and firmly do not loosen, reach the effect of sealing.The top of high-strength insulator 4 inside is respectively arranged with moving contact 3, upper static contact 5, inner wall insulation pipe 8, insulation arc-extinguishing tube 6, double fluid fusing insurance 7; Upper static contact 5 adopts slide block to be connected with upper moving contact 3, the bottom of high-strength insulator 4 inside is respectively arranged with lower moving contact 9, contact fixes card 10, lower fixed contact 11, bolt 12, fusion tube lower spring 13, insulation and obturation cover 14, lower spring fix card 15, fuse fixing support 16, and lower fixed contact 11 adopts spring to be connected with lower moving contact 9.
This embodiment is when double fluid fusing insurance 7 disconnects, and the slide block that upper static contact 5 adopts with upper moving contact 3 is connected the damage effectively reduced operational outfit.
It forms a closed environment by high-strength insulator and insulation water-resisting mask and insulation and obturation cover.Fuse built-in system is normally run, not by external environment variable effect, makes the operation of protected cut-out more reliable and stable.
This embodiment has following beneficial effect: effectively reduce the damage to operational outfit, fixed, easy to use, easy and simple to handle, increases the service life.
The foregoing is only preferred embodiment of the present utility model; not in order to limit the utility model; all within spirit of the present utility model and principle, any amendment done, equivalent replacement, improvement etc., all should be included within protection range of the present utility model.
