Abstract
The utility model discloses a high voltage isolating type fuse switch. Two ends on a base seat (1) are provided with two porcelain vases (2) (14) which are fixed with an insulating joint piece (3) and a static contact head (12) which is provided with an input connection terminal (13). The insulating joint piece (3) is movably connected with a plate-shaped insulating joint rod (4), a conducting connecting rod (6) which is provided with an output connection terminal (5), a fuse (8) and a plate-shaped moving contact head (10), which are orderly connected with each other. The utility model which is used for mechanical equipment is taken as a protector of a high voltage current of more than 6000 volts. The utility model has the advantages of high sensitivity, easy operation and maintenance, simple structure, light weight, and convenient move and use.
Description
The utility model belongs to electric current by its fusible material, when this electric current is excessive, owing to the fusing of fusible material makes the protective device of current interruptions, is specially the isolated fuse cutout of a kind of high pressure.
Present protective device at employed high-tension current on the plant equipment of large-scale factories and miness (more than 6000 volts); what generally adopt is to be provided with air switch, relay or circuit breaker in the power distribution cabinet; the protective device of the high-tension current that air switch, relay or circuit breaker and power distribution cabinet are formed; its sensitivity is low; complex structure; huger heaviness moves and extremely inconvenient when using, and does not satisfy actual needs.
The purpose of this utility model provides the isolated fuse cutout of a kind of high pressure, and the isolated fuse cutout of this high pressure is highly sensitive, simple in structure, in light weight, moves with very easy to use, can satisfy actual needs.
To achieve these goals, the utility model is on two porcelain insulators that are equipped with at the two ends on the base, be fixed with the fixed contact that has the input wires terminal on insulated connecting piece and its respectively, flexibly connecting successively by tabular insulated connecting rod, the conduction connecting rod that has output wiring terminal on it, fuse, tabular moving contact on the insulated connecting piece.
The utility model is as the protective device of 6000 volts of used above high-tension currents of the plant equipment of large-scale factories and miness; when lead, cable or plant equipment break down; when electric current is excessive; but the melt in the fuse of this switch is quick fuse just; pass through to cut off electric current; reach the purpose of protective effect, guarantee safety.After the melt fusing of fuse, moving contact and fixed contact can be disengaged, fuse is changed again.The utility model is highly sensitive, easily operation, and maintenance and to change fuse convenient, fail safe is good, and is simple in structure, in light weight, moves and use all very convenient, can satisfy actual needs.
Below in conjunction with accompanying drawing this practicality is explained
Fig. 1: schematic diagram of the present utility model
The utility model is that two ends on the base 1 of the cuboid of a length are fixed with porcelain insulator 2 and porcelain insulator 14, be fixedly connected with " U " type insulated connecting piece 3 on the porcelain insulator 2, be fixed with its outer end on the porcelain insulator 14 and have input wires terminal 13, inner end is to curve vertical configuration to have the tabular fixed contact 12 that projection is struck the post, be connected with tabular insulated connecting rod 4 in the insulated connecting piece 3, the both sides of insulated connecting rod 4 front portions are fixedly connected with the tabular conduction connecting rod 6 that the end has output wiring terminal 5 by set bolt 7, the end of conduction connecting rod 6 and insulated connecting rod 4 is fixedly connected with the stopped pipe type fast acting fuse 8 of filleding and endcloseing cartridge fuse-link of the bath component of the arc-extinguishing medium that is built-in with by glass fibre reinforced plastic cylinder 9 with at glass fibre reinforced plastic cylinder 9 and filamentary silver or silver strip, be equipped with indicating device 801 on the fuse 8, the other end of fuse 8 is fixedly connected with the tabular conductive moving contact 10 that contacts with fixed contact 12 and to fasten, and the melt in the fuse 8 and conduction connecting rod 6 are separated 10 and are connected with tabular moving.
Be equipped with snap close 11 and lockhole on the tabular moving contact 10, when moving contact 10 contacts with fixed contact 12 when fastening, fixed contact 12 inserts in the lockhole of moving contacts 10, the projection on the fixed contact 12 strike the post with moving contact 10 on snap close 11 be interlocked together.
