Description
Technical field
The invention belongs to technical field of electricity, particularly relate to a kind of renewable type fusible cut-out.
Background technology
Fusible cut-out is widely used in high and low voltage electric distribution system and Controlling System and electrical equipment, as the protector of short circuit and super-high-current, is apply one of the most general protection device. General fusible cut-out divides the electrical equipment of deenergizing using metallic conductor as melt, is series in circuit, and when transshipping or short-circuit current passes through melt, heating self is fused by melt, not reproducible use, and economy is not high, and often to be gone to change melt.
Summary of the invention
The present invention is in order to solve weak point of the prior art, it is provided that a kind of can change melt, can reuse and have good economy renewable type fusible cut-out.
For solving the problems of the technologies described above, the present invention adopts following technical scheme: renewable type fusible cut-out, comprise the shell in tubular structure, through hole in axial direction it is provided with in shell, shell two ends are respectively equipped with the wire current terminal of shutoff at through hole two ends and outlet electric current terminal, the ceramic insulating tube being positioned at wire current terminal side it is provided with in through hole, micalex layer it is equipped with between through-hole wall and ceramic insulating tube outer wall and between wire current terminal and shell, it is provided with in through hole and the Metal Ball of outlet electric current termination contact, Metal Ball contacts with through-hole wall and seals, ceramic insulating tube between wire current terminal and Metal Ball and be filled with sodium Metal 99.5 in through hole, the high pressure argon gas of 20 MPas it is filled with between the inherent Metal Ball of through hole and outlet electric current terminal.
Described shell adopts austenitic stainless steel material to make, and ceramic insulating tube adopts beryllium oxide material to make, and the outside surface of shell is provided with insulation layer.
Described wire current terminal and outlet electric current terminal are threaded with shell two ends respectively, and wire current terminal and outlet electric current terminal junction with shell are provided with sealing-ring respectively.
Adopting technique scheme, the present invention connects in circuit, and during normal operation, wire current terminal, sodium Metal 99.5, Metal Ball are connected with outlet electric current terminal, make conduction loop through; When there is short circuit or overload when circuit, when sodium Metal 99.5 temperature increases above boiling point 882.9 DEG C, sodium Metal 99.5 gasifies, and Metal Ball is backed down and is separated with outlet electric current terminal by the high pressure argon gas of 20 MPas, and circuit is disconnected, and plays the effect of circuit safety protection. When the temperature decreases, sodium Metal 99.5 returns to solid-state, and compressing Metal Ball continues and outlet electric current termination contact, reuses.
Shell adopts austenitic stainless steel material to make, and prevents corrosion under dark wet environment. Wire current terminal and outlet electric current terminal are threaded with shell two ends respectively, are convenient to installing/dismounting, and the setting of sealing-ring guarantees that inner argon gas and sodium Metal 99.5 do not leak.
Inventive design is reasonable, and structure is simple, safe and reliable, it is not necessary to changes melt, can reuse, have good economy, practical, is easy to apply.
Accompanying drawing explanation
Fig. 1 is the structural representation of the present invention.
Embodiment
As shown in Figure 1, the renewable type fusible cut-out of the present invention, comprise the shell 1 in tubular structure, through hole 7 in axial direction it is provided with in shell 1, shell 1 two ends are respectively equipped with the wire current terminal 2 of shutoff at through hole 7 two ends and outlet electric current terminal 3, the ceramic insulating tube 9 being positioned at wire current terminal 2 side it is provided with in through hole 7, micalex layer 4 it is equipped with between through hole 7 inwall and ceramic insulating tube 9 outer wall and between wire current terminal 2 and shell 1, it is provided with in through hole 7 and the Metal Ball 6 that outlet electric current terminal 3 contacts, Metal Ball 6 is with through hole 7 contact internal walls and seals, ceramic insulating tube 9 between wire current terminal 2 and Metal Ball 6 and be filled with sodium Metal 99.5 5 in through hole 7, the high pressure argon gas of 20 MPas it is filled with between the inherent Metal Ball 6 of through hole 7 and outlet electric current terminal 3.
Shell 1 adopts austenitic stainless steel material to make, and ceramic insulating tube 9 adopts beryllium oxide material to make, and the outside surface of shell 1 is provided with insulation layer 10.
Wire current terminal 2 and outlet electric current terminal 3 are threaded with shell 1 two ends respectively, and wire current terminal 2 and outlet electric current terminal 3 junction with shell 1 are provided with sealing-ring 8 respectively.
The present invention connects in circuit, and during normal operation, wire current terminal 2, sodium Metal 99.5 5, Metal Ball 6 are connected with outlet electric current terminal 3, make conduction loop through; When there is short circuit or overload when circuit, when sodium Metal 99.5 5 temperature increases above boiling point 882.9 DEG C, sodium Metal 99.5 5 gasifies, and Metal Ball 6 is backed down and is separated with outlet electric current terminal 3 by the high pressure argon gas of 20 MPas, and circuit is disconnected, and plays the effect of circuit safety protection. When the temperature decreases, sodium Metal 99.5 5 returns to solid-state, and compressing Metal Ball 6 continues to contact with outlet electric current terminal 3, reuses.
Shell 1 adopts austenitic stainless steel material to make, and prevents corrosion under dark wet environment. Wire current terminal 2 and outlet electric current terminal 3 are threaded with shell 1 two ends respectively, are convenient to installing/dismounting, and the setting of sealing-ring 8 guarantees that inner argon gas and sodium Metal 99.5 5 do not leak.
Above-described embodiment is not that the shape to the present invention, material, structure etc. do any restriction in form; every any simple modification, equivalent variations and modification above embodiment done according to the technical spirit of the present invention, all belongs to the protection domain of technical solution of the present invention.
