Description
Technical field
The utility model relates to field of electrical equipment, relates in particular to a kind of insulation Hi-pot test wire.
Background technology
At present, when the high-tension apparatus of power plant or transformer station carries out high-potting, use the wire of fixed insulation grade to carry out wiring test always, and insulated conductor is not identical to the insulation distance of test pressurized equipment direction along the line from tested high-tension apparatus, need different wire insulation intensity, generally by insulating cord increase insulation distance or insulating mat, make up the problem that dielectric strength is inadequate now, but insulating cord or insulating mat are difficult fixing, easily cause in test insulating cord or insulating mat to come off, and then cause test loop electric discharge to interrupt, increased thus potential risk.
Utility model content
(1) technical matters that will solve
The purpose of this utility model is to provide the adjustable Hi-pot test insulated conductor of a kind of insulation distance, to adapt to tested high-tension apparatus to the different insulation distance requirement in whole loop between test pressurized equipment.
(2) technical scheme
For solving the problems of the technologies described above, the utility model provides a kind of insulation Hi-pot test wire, it comprises insulated conductor, insulation sleeve and snap ring, the two ends of described insulated conductor are terminals, described insulation sleeve is a plurality of, a plurality of described insulation sleeves are arranged along the length direction of described insulated conductor, are sleeved on respectively the outside of described insulated conductor by snap ring.
Further, the outside of described snap ring and the inner side of described insulation sleeve are fixed, and the inner side of described snap ring is connected with the outside of described insulated conductor.
Further, described snap ring is elastic clip, and the outside of described elastic clip and the inner side of described insulation sleeve are fixed, and the inner side of described elastic clip is pressed on the outside of described insulated conductor.
Further, the thickness of described insulation sleeve is 1-3cm.
Further, described in each, the two ends of insulation sleeve are equipped with snap ring and are connected with described insulated conductor.
(3) beneficial effect
A kind of insulation Hi-pot test wire that the utility model provides, by a plurality of insulation sleeves are set on insulated conductor, dielectric strength is optional, make the insulation classification of Hi-pot test wire variable, can adapt to the different insulation distance requirement of tested high-tension apparatus to whole test loop between test pressurized equipment along insulated conductor.
Accompanying drawing explanation
Fig. 1 is the structural representation of the utility model insulation Hi-pot test wire.
In figure: 1, insulated conductor; 2, insulation sleeve; 3, snap ring.
Embodiment
Below in conjunction with drawings and Examples, embodiment of the present utility model is described in further detail.Following examples are used for illustrating the utility model, but are not used for limiting scope of the present utility model.For the ordinary skill in the art, can concrete condition understand the concrete meaning of above-mentioned term in the utility model.
As shown in Figure 1, a kind of insulation Hi-pot test wire of the present utility model, it comprises insulated conductor 1, insulation sleeve 2 and snap ring 3, the two ends of insulated conductor 1 are terminals, insulation sleeve 2 is a plurality of, a plurality of insulation sleeves 2 as insulating element are along the length direction layout of insulated conductor 1, and insulation sleeve 2 is sleeved on respectively the outside of insulated conductor 1 by snap ring 3.Wherein, snap ring 3 can only arrange in one end of insulation sleeve 2, or, for reinforced insulation cover 2 is connected with insulated conductor 1 firm, preferably, the two ends of each insulation sleeve 2 are equipped with snap ring 3 and are connected with insulated conductor 1.
Snap ring 3 is relative with insulation sleeve 2 fixing, and position between insulation sleeve 2 and insulated conductor 1 is adjustable, and treating can be relatively fixing after position adjustments.Can be: the inner side of the outside of snap ring 3 and insulation sleeve 2 is fixed, the inner side of snap ring 3 be connected with the outside of insulated conductor 1.Or be: snap ring 3 is elastic clip, and the inner side of the outside of this elastic clip and insulation sleeve 2 is fixed, and the inner side of this elastic clip is pressed on the outside of insulated conductor 1, by the elastic reaction of elastic clip self, insulation sleeve 2 can be adjusted to suitable position.
Preferably, the thickness of insulation sleeve is 1-3cm, and the effect that this thickness is set is the dielectric strength that strengthens existing insulated conductor part, and this thickness range can meet the requirement of on-the-spot Insulation Test substantially.
The insulation Hi-pot test wire that technique scheme provides, its specific works process is: during high-potting, insulated conductor with insulation sleeve 31 is connected to test loop, two terminals of insulated conductor 1 are connected with test pressurized equipment with tested high-tension apparatus respectively, the place of insulation distance deficiency in test loop is found out in inspection, insulation sleeve 2 is adjusted to the not enough place of insulation distance, and fixing with snap ring 3, can carry out applied voltage test.
Insulation Hi-pot test wire of the present utility model, by a plurality of insulation sleeves are set on insulated conductor, dielectric strength is optional, make the insulation classification of Hi-pot test wire variable, can adapt to the different insulation distance requirement of tested high-tension apparatus to whole test loop between test pressurized equipment along insulated conductor.
The above is only preferred implementation of the present utility model; should be understood that; for those skilled in the art; do not departing under the prerequisite of the utility model know-why; can also make some improvement and replacement, these improvement and replacement also should be considered as protection domain of the present utility model.
