Abstract
The utility model provides a closed high voltage fuse, which comprises a fused mass, an arc extinguishing tube and a fuse component which is formed by a lead wire and a spring and arranged in an insulation tube. The spring can accelerates the disjunction of fusing the fuse mass either in method of compressing and storing energy, or in method of pulling and storing energy. By use of the closed high voltage fuse technology, the fuse can effectively prevent the opening and breaking performance of the fuse from going bad caused by inappropriate assembly, spring corrosion and clamping and so on, thereby greatly improving the protection reliability of the fuse.
Description
The utility model is applied in the high-tension fuse, relates to a kind of fuse.
In the prior art, the fuse that is used for the High-Voltage Electrical Appliances error protection all is to adopt torque spring, and spring is external.Adopt this fuse that three weak points are arranged.The first, an arm of force must be fixed on the electrical equipment sleeve pipe, make sleeve stress, fragile sleeve pipe; The second, fuse needs site installation and installs, require very high, as setting angle, highly, tension force etc. is all strict is undertaken by standard, otherwise may cause fuse normally not cut-off; The 3rd, adopt torque spring, and spring is external, make the spring easy-to-rust destroy break performance with relaxing.Just because of these deficiencies cause existing fuse failure rate higher.Therefore, people are that the performance of improving fuse has adopted thousand and one way.As the patent No. is in the patent of 90214667.X, and promptly the lead that links to each other with melt by the torsion spring tension with the improvement break performance, but does not address the above problem.And for example scientific and technological classification number is that the fuse that TM563, title are introduced for " BRW-6/12.5P type shunt capacitor protecting single high-tension fuse " also exists the problems referred to above, and makes the protective value of fuse be difficult for guaranteeing.
The purpose of this utility model provides a kind of brand-new, need not assemble at the scene, has the closed high-tension fuse of anti-corrosion, corrosion proof function, to guarantee the protective value of fuse, improves the operational reliability of High-Voltage Electrical Appliances.
The utility model of realizing above-mentioned purpose provides a kind of site installation that do not need, and has the closed high-tension fuse of anti-corrosion, corrosion proof function.It is characterized in that melt 1 is installed within the arc-extinguishing tube 2, melt 1 is drawn by lead 3, and lead 3 passes spring 4 and compresses (or tension), is assembled within the insulated tube 5, the two ends of insulated tube 5 are fixed at the two ends of this assembly respectively by termination 6 and end cap 7, form a closed high-tension fuse.
In electric power system, adopt the closed high-tension fuse of the utility model; can prevent effectively that the fuse installation is improper; the defective of spring corrosion, the loosening break performance variation of being brought; the destruction that can avoid the sleeve stress of electric equipment effectively and cause; improve the protection reliability of fuse, reach the purpose that improves the security appliance reliability.
The utility model is described in further detail below in conjunction with accompanying drawing.
1 is melt among the figure, the 2nd, and arc-extinguishing tube, the 3rd, lead, the 4th, spring, the 5th, insulated tube, the 6th, termination, the 7th, end cap.
Among the figure, on fuse, adopted the closed high-tension fuse of the utility model.In fuse, spring 4 directly in factory-assembled among insulated tube 5, spring both can adopt the compress mode energy storage, also can adopt the stretching energy storage, to improve the fuse break performance.Because fuse has been assembled in factory and has been finished, and does not need site installation, so stable performance.The built-in fuse that makes of this outer spring is an obturator, and spring, melt are greatly reduced by atmospheric Corrosion, have reached antirust, corrosion-resistant purpose, thereby has increased the useful life and the reliability of fuse.
Claims (2)
1. closed high-tension fuse, melt 1 is installed in the arc-extinguishing tube 2, melt 1 is drawn by lead 3, lead 3 passes spring 4, spring 4 compresses or strains and is assembled in the insulated tube 5, and be closed in the insulated tube 5 by termination 6 and end cap 7, it is characterized in that melt 1 places in the arc-extinguishing tube 2, and be packaged in the insulated tube 5 with spring 4.
2. closed high-tension fuse according to claim 1 is characterized in that: spring 4 is assemblied in the insulated tube 5, can be compression energy storage mode, also can be stretching energy storage mode.
