Abstract

The utility model discloses a simulation impactor of a fuse, and comprises an outer shell with the same shape as the fuse, and an electromagnet ejection component. The electromagnet ejection component comprises an electromagnetic coil outer casing, a shaft sleeve, a coil, and a moveable iron core moveably sleeved in the shaft sleeve; a magnet steel and a fixed iron core which are fixed at one end of the shaft sleeve are positioned in the outer casing; the moveable iron core is longer than the shaft sleeve, and extends out of the end cover of the outer casing at the other end of the shaft sleeve; a spring is sleeved outside an extension part and fixed between a boss at the outer end of the moveable iron core and the end cover of the outer casing; a boss is arranged at one end of the inner side of the moveable iron core; the diameter of the boss is larger than the aperture of the end cover of the outer casing; a push rod is formed at the outer end of the moveable iron core, and the outer shell extends out of the end cover of the outer shell; when an electromagnet is powered on to work, the moveable iron core is pushed into an extension state, and a disconnecting switch element is impacted, so as to cause the disconnecting switch to operate. The simulation impactor suits the task of the performance test of the over-current protective disconnecting switch in a power transmission line, and has the advantages of safety, low cost, etc.

Description

The simulating impact device of fuse
Technical field
The utility model relates to a kind of power transmission system and gets overcurrent protective device.
Background technology
Work as in traditional power transmission system and use fuse application of load switches set to become combined electrical apparatus; fuse is equipped with the overcurrent catapult-launching gear, and when short circuit current burnt fuse, this catapult-launching gear triggered the sincere son of on-load switch separating brake; on-load switch is disconnected, with the safety of protection transmission line.In actual production and using, for the reliability of combined electrical apparatus unit is tested, can the test method that generally adopts be to verify and detain by Off with a mechanical type simulation fuse that has extended striker at present, for gas tank formula ring main unit, because its hermetically sealed and characteristic all insulation, producing product man even type approval test station all can not directly test its product, but adopt the way of mechanical impact device at the enterprising line sampling simulation test of special use test frock, come the approximate test of finishing its characteristic.Because the error of secondary installing, debugging, this device does not have accurate equivalence, and its measurement result is inaccurate.
Summary of the invention
The purpose of this utility model provides a kind of simulating impact device of fuse, and simulation fuse striker can replace fuse directly to pack in the switch cubicle, uses automatically controlled, Infrared remote controller can order it to carry out the fusing bump and move at any time.Can be aborning or carry out equivalence detection when install checking and accepting by platform.So just can reach the purpose of accurate debug switch cabinet fuse Off deduction structure power value size.
The simulating impact device of fuse described in the utility model comprises: have shell, the electromagnet identical with the fuse profile and launch assembly, power supply and control switch; Described electromagnet launches assembly and comprises solenoid overcoat, axle sleeve, is fixed in the movable moving iron core that is nested with in coil between overcoat and the axle sleeve, the axle sleeve by coil rack, is positioned at axle sleeve one end fixing magnet steel and fixed core in the overcoat; Described moving iron core grows axle sleeve, and is stretched out by the overcoat end cap of the axle sleeve other end, is with spring outside extension, spring is fixed between moving iron core outer end boss and the overcoat end cap, the inboard end of moving iron core has a boss, and its diameter and axle sleeve are suitable, greater than the aperture of overcoat end cap; Described electromagnet launches the outer of assembly and is placed in the shell, is fixed wherein by the shell end cap, and moving iron core outer end constitutes push rod and stretches out shell by the shell end cap; When electromagnet connect electricity work, moving iron core was pushed to when stretching out state, and extension elongation should satisfy the percussion cutting-off switch and put son, made the requirement of cutting off switch motion.
The simulating impact device of aforesaid fuse, control switch is the switch and the electric-controlled switch of remote controller control in the power supply of described solenoid.
Good effect of the present utility model is to provide a kind of novel test equipment for power transmission system.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
Fig. 2 is the structural representation that electromagnet of the present utility model launches assembly.
Embodiment
Embodiment of the present utility model is referring to accompanying drawing.Fig. 1 is the schematic diagram of the simulating impact device of fuse.In the shell 1 of a fuse profile, be provided with electromagnet and launch assembly 7, a supplying cell 3 and a remote control control board 2.Left end at shell 1 is a manual mains switch 4, and the right-hand member of shell 1 is the push rod 5 of a magnetic control.Fig. 2 is that the electromagnet that is installed in the shell launches the modular construction schematic diagram.In Fig. 2, the electromagnetic launch assembly comprises that the axle sleeve 9 in solenoid overcoat 18, the solenoid overcoat 18, coil 11, the axle sleeve 9 interior movable sleeves that are fixed between overcoat 18 and the axle sleeve 9 by coil rack are equipped with in moving iron core 10, the overcoat 18 and are positioned at magnet steel 16 and the fixed core 14 that axle sleeve 9 one ends are fixed.The base plate 17 that described magnet steel 16 outer ends are installed by solenoid overcoat 18 ends is fixing, and fixed core 14 is positioned at magnet steel 15 the inners.Between described magnet steel 16 and the solenoid overcoat 18 magnetic steel sleeve 15 is arranged, iron hoop cover 12 is arranged between fixed core 14 and the solenoid overcoat 18, iron hoop overlaps 12 both sides packing ring 13.Described moving iron core 10 grows axle sleeve 9, and is stretched out by the overcoat end cap 19 of axle sleeve 9 other ends.Be with spring 8 outside moving iron core 10 parts of stretching out, spring 8 is fixed between moving iron core 10 outer end boss shape screws 20 and the overcoat end cap 19.Moving iron core 10 inboard ends have a boss, and its diameter and axle sleeve are suitable, greater than the aperture of overcoat end cap 19; The overcoat 18 that described electromagnet launches assembly is placed in the shell 1, is fixed wherein by shell end cap 6, and moving iron core 10 outer ends are that push rod 5 stretches out shell by shell end cap 6.
Moving iron core is two kinds of operating states; A kind of is conventional state, will move iron core 10 and inwardly be pushed into and fixed core 14 contact positions, and solenoid 11 no power work this moment, the suction by magnet steel 16 overcomes the spring 8 tension force state that remains retracted; Another kind is an impact conditions, and when power supply Be Controlled switch connection, electromagnetic force overcomes the suction of magnet steel 16, and under the effect of compression spring 8, moving iron core 10 outwards ejects.Moving iron core 10 is ejected, and its length should satisfy the action request that the percussion cutting-off switch is put son.The simulating impact device of this fuse is after finishing percussion action, and moving iron core 10 is to back into conventional state by manual type.
