Description
Technical field:
The utility model relates to Novel drop type fuse, belongs to fuse technologies field.
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.
Current existing fuse in use needs to use ground connection link, hanging earthing conductor between transformer to fuse switch, ground wire operating lever and earth connection and staff's hypotelorism, can bring potential potential safety hazard and work inconvenience to maintainer.
Along with the increase year by year of load, wire diameter between power consumption equipment to fuse switch constantly increases, after hanging a whole set of earth connection, wire two ends connect the weight that copper device clamp bears a whole set of earth connection completely, greatly shorten the useful life of device clamp, add old damage degree, the probability of device clamp fracture strengthens.
And traditional ground connection link is used in distribution maintenance, must earth connection be removed when lead-in wire and device clamp under replacing fuse switch, not have the protection of earth connection to bring very large potential safety hazard; The personnel that hinder one's work work on change stand, earth connection and operating personnel's hypotelorism, and go between under changing fuse switch and establish, must remove earth connection during standby wire clamp, device clamp bears earth connection weight completely.
Utility model content:
For the problems referred to above, the technical problems to be solved in the utility model is to provide Novel drop type fuse.
Novel drop type fuse of the present utility model, it comprises fusion tube, cast steel pipe box, gudgeon, baffle plate, the first connecting plate, the second connecting plate, insulator, grounding hook and bolt; The lower end of fusion tube is socketed with cast steel pipe box, the both sides of cast steel pipe box side are all connected with baffle plate by gudgeon, the side of two baffle plates is fixed with the first connecting plate and the second connecting plate by screw, the lower end of the first connecting plate has been bolted grounding hook, one end of second connecting plate is connected with insulator, described grounding hook comprises fixed head and hook, and fixed head and the first connecting plate are connected and fixed, and hook is arranged on the lower end of fixed head side.
The beneficial effects of the utility model are: it has had better personal safety to ensure when line maintenance, improve the fail safe in operation, reliability simultaneously.Reduce the probability of causing danger in operation, ensured the safe and reliable of operation power, thus produce considerable economic and social benefit.
Accompanying drawing illustrates:
For ease of illustrating, the utility model is described in detail by following concrete enforcement and accompanying drawing.
Fig. 1 is structural representation of the present utility model,
Fig. 2 is the structural representation of grounding hook 8 in the utility model.
In figure: 1-fusion tube; 2-cast steel pipe box; 3-gudgeon; 4-baffle plate; 5-first connecting plate; 6-second connecting plate; 7-insulator; 8-grounding hook; 9-bolt; 8-1-fixed head; 8-2-links up with.
Embodiment:
For making the purpose of this utility model, technical scheme and advantage clearly understand, below by the specific embodiment shown in accompanying drawing, the utility model is described.But should be appreciated that, these describe just exemplary, and do not really want to limit scope of the present utility model.In addition, in the following description, the description to known features and technology is eliminated, to avoid unnecessarily obscuring concept of the present utility model.
As shown in Figure 1-2, this embodiment by the following technical solutions: it comprises fusion tube 1, cast steel pipe box 2, gudgeon 3, baffle plate 4, first connecting plate 5, second connecting plate 6, insulator 7, grounding hook 8 and bolt 9; The lower end of fusion tube 1 is socketed with cast steel pipe box 2, the both sides of cast steel pipe box 2 side are all connected with baffle plate 4 by gudgeon 3, the side of two baffle plates 4 is fixed with the first connecting plate 5 and the second connecting plate 6 by screw, the lower end of the first connecting plate 5 is connected with grounding hook 8 by bolt 9, one end of second connecting plate 6 is connected with insulator 7, described grounding hook 8 comprises fixed head 8-1 and hook 8-2, fixed head 8-1 and the first connecting plate 5 is connected and fixed, and hook 8-2 is arranged on the lower end of fixed head 8-1 side.
This embodiment operates very convenient, after pulling open fuse switch, can direct hanging earthing conductor, and practical value is high; The position of hanging earthing conductor does not affect staff's normal running, does not aggravate the aging of other connection device; Earth connection need not be removed for ensuring safety when changing lead-in wire and device clamp under fuse switch.
More than show and describe general principle of the present utility model and principal character and advantage of the present utility model.The technical staff of the industry should understand; the utility model is not restricted to the described embodiments; what describe in above-described embodiment and specification just illustrates principle of the present utility model; under the prerequisite not departing from the utility model spirit and scope; the utility model also has various changes and modifications, and these changes and improvements all fall within the scope of claimed the utility model.The claimed scope of the utility model is defined by appending claims and equivalent thereof.
