Description
Technical field
The utility model belongs to high tension distribution system technical field, relates to a kind of fuse.
Background technology
At present, for high tension distribution system protection fuse primarily of two kinds of forms, one is current-limiting type fuse, another be spray let out type fuse.Current-limiting type fuse blows ability is large, and owing to not having free gas to spray when fusing, can not pollute surrounding environment, be therefore used as short trouble protection in actual applications, but this current-limiting type fuse can not provide protection for low value fault current; Spray is let out type fuse and is had superior small area analysis fusing performance, but its blowout current is limited in one's ability, and do not possess specified restriction accurately, in addition, type fuse is let out in this spray can produce noise when fusing, and ejects free gas and regulus, therefore, type fuse is let out in this spray can not with indoors, and be all generally that the switch being used as Standard type carrys out use, range of application is little.
Utility model content
The purpose of this utility model is to provide a kind of fuse, and application scenario is unrestricted, and the wide ranges of blowout current.
The technical scheme that the utility model adopts is, a kind of fuse, comprise earthenware, ceramic tube inside is provided with connector, connector earthenware is divided into current limliting melt space and melt space two parts are let out in spray, also be provided with temperature sensor in earthenware, temperature sensor is connected with temperature comparison module and alarm successively, and alarm is installed on high voltage power distribution cashier's office in a shop;
Be provided with multiple melt a in current limliting melt space, the outer surface of multiple melt a is all welded with metal dots, and the two ends of melt a are connected with contact point and connector respectively, and the outer surface of melt a also overlaps and has flexible pipe;
Spray is let out in type melt space and is provided with multiple melt b, and each melt b is wound around by two one metal wires and forms, and the two ends of multiple melt b are connected with connector and contact point respectively;
Current limliting melt space and spray are let out in melt space and are distributed with filler.
Feature of the present utility model is also,
The quantity of melt a is 3, and is arranged in parallel in current limliting melt space.
The metal dots of melt a outer surface is tin sweat(ing).
Melt a and melt b is the silver-colored or silver-plated copper of copper.
The filler that melt space is let out in current limliting melt space and spray is quartz sand.
The color of alarm is red or green.
The beneficial effects of the utility model are by being connected by two kinds of dissimilar fuses; reliably protecting can be provided to low value fault current; there is enough wide electric current and energy limited field; frame for movement is firm; and be arranged on high voltage power distribution alarm cashier's office in a shop can point out operator on duty's fault and overhaul in time circuit, ensure that circuit normally works.
Accompanying drawing explanation
Fig. 1 is the structural representation of a kind of fuse of the utility model.
In figure, 1. melt pipe, 2. connector, 3. melt a, 4. contact point, 5. melt b, 6. temperature sensor, 7. temperature comparison module, 8. alarm, 9. flexible pipe.
Detailed description of the invention
Below in conjunction with the drawings and specific embodiments, the utility model is described in detail.
A kind of fuse of the utility model, as shown in Figure 1, comprise earthenware 1, earthenware 1 inside is provided with connector 2, earthenware 1 is divided into current limliting melt space with connector 2 and melt space two parts are let out in spray, also be provided with temperature sensor 6 in earthenware 1, temperature sensor 6 is connected with temperature comparison module 7 and alarm 8 successively, and alarm 8 is installed on high voltage power distribution cashier's office in a shop; Be provided with multiple melt a3 in current limliting melt space, the outer surface of multiple melt a3 is all welded with metal dots, and the two ends of melt a3 are connected with contact point 4 and connector 2 respectively, and the outer surface of melt a3 also overlaps and has flexible pipe 9; Spray is let out in type melt space and is provided with multiple melt b5, and each melt b5 is wound around by two one metal wires and forms, and the two ends of multiple melt b5 are connected with connector 2 and contact point 4 respectively; Current limliting melt space and spray are let out in melt space and are distributed with filler.The quantity of melt a3 is 3, and is arranged in parallel in current limliting melt space.The metal dots of melt a3 outer surface is tin sweat(ing).Melt a3 and melt b5 is the silver-colored or silver-plated copper of copper.The filler that melt space is let out in current limliting melt space and spray is quartz sand.The color of alarm 8 is red or green.
Fuse of the present utility model is when there being low value fault current to flow through, the spray with the tin sweat(ing) of M effect is let out type melt and is first fused, electric arc is produced at incision position, because each melt a3 is in parallel, in melting process, melt fusing has sequencing, the gas of discharging in fusing process and slag, can overflow from flexible pipe 9, and absorb by the filler quartz sand in earthenware 1, when there is major break down electric current, the heating of melt is similar to adiabatic process, heat has little time to conduct in various piece, M effect tin sweat(ing) has little time fusing, so first a limit bridge on current-limiting type melt fuses, temperature sensor 6 can detect the temperature in earthenware 1, temperature is sent to temperature comparison module 7, temperature comparison module 7 can contrast the fusing point of this temperature and tin sweat(ing), if temperature reaches the fusing point of tin sweat(ing), then control alarm 8 to report to the police, after operator on duty hears that alarm 8 is reported to the police, can overhaul fault, thus ensure that circuit is normal.
Very fast owing to being at high temperature oxidized, and oxidation seriously can affect fusing performance, therefore, in order to anti-oxidation, carries out silver-plated at the outer surface of copper melts.
The outer surface of temperature sensor 6 is coated with sheath, is to prevent from spraying the gas letting out and spray in type melt fusing process and slag damages temperature sensor.
