Abstract
The utility model discloses an experimental short termination, including two fasteners, spacing bayonet lock, one roll flat type copper wire, flexible reel and casing, the casing including upper cover and lower cover, be provided with spacing bayonet lock through -hole last covering, be provided with the screw hole at the middle part of upper cover, lower covering be provided with the upright barrel arbor that makes progress, flexible reel have a plurality of spacing draw -in grooves, two cable cleat install are at flat type copper wire's both ends, flat type copper wire settles in flexible reel, the barrel arbor of lower cover upwards passes lower half, the flat type copper wire of flexible reel, first one of flexible reel in proper order, to the screw hole department at the casing upper cover, both use screw locking, spacing bayonet lock is inserted and is used in the spacing hole of casing upper cover. The clip that uses this kind of shorting stub to use when connecting has enough big clamping -force, can not drop because of the change of surrounding environment when testing, even drop, during the reel of device can be rapidly be drawn into the reel with it.
Description
Technical field
This utility model relates to a kind of short jumper device, particularly a kind of test short jumper device.
Background technology
In power industry, owing to operation danger coefficient is the highest, it is required for carrying out shorting stub test to all kinds of electrical equipments, existing when carrying out shorting stub test, mostly use iron wire or other wire to be directly wound around and carry out, this short circuit test method, easily drop in process of the test, and for some equipment, owing to there is no to be wound around the place of wire, cause test cannot be carried out.
Utility model content
In place of the purpose of this utility model is to overcome the deficiencies in the prior art, and provide a kind of test short jumper device applied widely, adeciduate during use, safe and reliable.
A kind of test short jumper device, include two wire clamps, spacing bayonet lock, the flat type copper wire of volume, one flexible reel and housing, described housing includes upper cover and lower cover, and upper covering is provided with spacing bayonet lock through hole, and this spacing bayonet lock through hole links up the top and bottom of upper cover, be provided with screwed hole at the middle part of upper cover, described under cover and be provided with the most upright spool shaft；Described flexible reel has multiple spacing draw-in groove, two wire clamps are arranged on the two ends of flat type copper wire, flat type copper wire is placed in flexible reel, the spool shaft of lower cover upwards sequentially passes through the lower half of flexible reel, flat type copper wire, the first half of flexible reel, it is against at the screwed hole of case top lid, both use screw lock, and spacing bayonet lock is inserted in the spacing hole of case top lid use.
When using this test short jumper device, when as test wire, the length to electrical equipment (such as vacuum circuit breaker) biphase binding post is pulled open in test shorting stub, then it is clamped on two binding posts of testing equipment (such as A, B phase), take a test short jumper device again and be clamped in another two upper (such as B, C phases), this completes the work of three-phase short circuit, follow-up work can be proceeded by with that；When removing shorting stub, as long as being taken down by two wire clamps, the line of pull-out will be taken in reel by reel automatically.
When test shorting stub is used as earth lead use, test shorting stub is pulled open to appropriate length, then limiting card is slightly pressed, block reel, make line will not be involved in by reel, the two ends of shorting stub are held with being clipped in the earth terminal with equipment the most again.During dismounting, first slightly being extracted by limiting card, taking down two wire clamps, the line of pull-out is taken in reel by reel automatically.
In sum, this utility model following advantage compared to existing technology:
1, easy to operate, spiral take-up is simple, it is not necessary to artificial take-up.
2, this device is testing large batch of electrical equipment (such as house dog on-load switch, vacuum circuit breaker and oil-immersed type transformer etc.), time saving and energy saving, reduces cost and puts into；
When 3, using this device to test at the scene, safety increases.Former use wire twist is sometimes prone to come off, and which increases the risk of test；The clip using this kind of shorting stub to use when connecting has sufficiently large chucking power, will not come off because of the change of surrounding at the trial, even if coming off, the reel of device can be involved in reel rapidly.
