Abstract
The utility model discloses a tap protective cover used for a transformer. The tap protective cover used for the transformer comprises an insulation cover, bakelite screws, insulation nuts and insulation caps, wherein two holes are formed in the upper portion of one side of the right surface of the insulation cover and the two holes are arranged corresponding to transformer taps in a longitudinal direction, two holes are formed in the lower portion of the other side of the right surface of the insulation cover and the two holes are arranged corresponding to transformer taps in the longitudinal direction, the bakelite screws are correspondingly arranged in any two holes at the two sides which are opposite, the insulation nuts are arranged at ends of the bakelite screws, and the insulation caps are arranged on other two holes. The tap protective cover used for the transformer overcomes the problems that insulation level is low between the transformer taps, a short-circuit occurs to a transformer easily and suspension potential is generated when a nut is pre-buried in a pouring body in the prior art, and the tap protective cover used for the transformer has the advantages of being simple in structure, safe and reliable, low in price, and capable of protecting the taps, increasing electrical distances between the taps, eradicating short circuit of the transformer and ensuring that the suspension potential is not generated.
Description
Technical field
The utility model relates to transformer technology, is a kind of tap protective cover for transformer specifically.
Background technology
Present most of transformer producer, dry-type transformer high pressure cast tap all exposed outside or adopt embedded nut fixed blade guard in the high pressure pour mass, its shortcoming mainly contains:
1, tap is exposed and piles up dust easily, and the dust over time accumulation can reduce the insulation level between the load tap changer;
2, cause transformer short-circuit easily;
3, embedded nut can produce outstanding current potential in pour mass.
The utility model content
The purpose of this utility model is to overcome the deficiency that above prior art exists, and provides electrical distance between a kind of simple in structure, safe and reliable, low cost, protection tap, the tap to be improved, to stop transformer short-circuit and does not produce the tap protective cover that is used for transformer of floating potential.
In order to achieve the above object, the utility model by the following technical solutions: a kind of tap protective cover for transformer comprises insulating cover, bakelite screw rod, insulation nut and insulator cap; Wherein, the vertical corresponding load tap changer in insulating cover front surface one side top is offered 2 holes, the vertical corresponding load tap changer in insulating cover front surface opposite side below is offered 2 holes, the any 2 hole correspondences in both sides arrange the bakelite screw rod relatively, the bakelite screw end head arranges the insulation nut, and other 2 holes arrange insulator cap.
As a kind of preferred construction, described insulating cover is the polymethyl methacrylate insulating cover.
As a kind of preferred construction, described insulating cover is the rubber-covered cover.
As a kind of preferred construction, described bakelite screw rod is nylon bakelite screw rod.
As a kind of preferred construction, described insulation nut is nylon insulation nut.
As a kind of preferred construction, described insulation nut is the rubber-covered nut.
For the ease of processing, the described insulating cover structure that is formed in one.
As a kind of preferred construction, described insulator cap is the nylon insulator cap.
As a kind of preferred construction, described insulator cap is the rubber-covered cap.
Operation principle of the present utility model: a kind of tap protective cover for transformer comprises insulating cover, bakelite screw rod, insulation nut and insulator cap; Wherein, the vertical corresponding load tap changer in insulating cover front surface one side top is offered 2 holes, the vertical corresponding load tap changer in insulating cover front surface opposite side below is offered 2 holes, the any 2 hole correspondences in both sides arrange the bakelite screw rod relatively, the bakelite screw end head arranges the insulation nut, and other 2 holes arrange insulator cap.During use, insulating cover covers on the tap outside, and the hole of insulating cover outer surface left side topmost and the hole of right side foot arrange bakelite screw rod and insulation nut, are used for the fixed insulation cover, the hole of the tap of other 2 hole correspondences connects the gear sheet, and hole corresponding on insulating cover arranges insulator cap.
The utility model has following advantage and effect with respect to prior art:
1, the utility model has adopted insulating cover, bakelite screw rod, insulation nut and insulator cap; Have the advantages that the electrical distance between simple in structure, safe and reliable, low cost and the tap is improved.
2, the utility model has been cancelled in the prior art structure of embedded nut fixed insulation cover in pour mass, has the advantages that not produce floating potential.
3, the utility model has adopted insulating cover, outside tap need not be exposed to, has protection tap and the characteristics of stopping transformer short-circuit.
