Abstract
The utility model relates to a dry high-voltage power metering box for measuring electric energy in high voltage for metering of a distribution transformer, which comprises a box body, a transformer and a porcelain tower, wherein the transformer in the box body is formed by casting epoxy resin integrally; both side walls of the box body are provided with ventilating shutters; the transformer formed by casting epoxy resin can prevent the transformer from discharging electricity to the box body so as to have the favorable insulating function and enhance the insulating property; the ventilating shutters at both of the two sides of the box body can effectively improve the radiating effect of the transformer in the box body; a skeleton of the transformer is made of pyroceram; the transformer made of pyroceram can prevent the wiring of the porcelain tower from discharging electricity caused by being close to the transformer. The utility model has the advantages that because the transformer is not soaked by the transformer oil, a large amount of transformer oil can be saved, the conditions of leakage, fire, explosion, etc. can be avoided, the insulating strength is enhanced and the use is convenient and safe.
Description
Technical field
The utility model relates to the electric power meter technical field, belongs to a kind of improvement of high-voltage power metering case.
Background technology
At present, widely used outdoor high-voltage electric metering box is to be used for the substation transformer high pressure to survey electric energy metrical, monitored meter is simplified a kind of measuring apparatus of power-supply unit, and the casing of this batch meter is made with metal, and mutual inductor is contained in the case, and in casing, fill with transformer oil, form the full formula of oil.The wiring of mutual inductor is connected in porcelain tower bottom with the wiring of porcelain tower, instrument box is equipped with in the casing side, though transformer oil can insulate and dispel the heat effectively, but in use easily cause seepage, be unsuitable under high-temperature condition, working, temperature raises and easily to cause discharge, on fire, blast, and transformer oil needs annual replacing once, causes very big waste.
Summary of the invention
The purpose of this utility model provides and a kind ofly adopts high pressure resistant nonmetallic materials, dry-type high-voltage electric metering box esy to use, safe and reliable without transformer oil, casing.
For achieving the above object, the utility model is taked following design proposal:
A kind of substation transformer high pressure that is used for is surveyed the dry-type high-voltage electric metering box that electric energy metrical uses, it includes casing, mutual inductor, porcelain tower, it is characterized in that: the mutual inductor in the casing adopts one-body molded the making of epoxy resin casting, is provided with the ventilation window shutter at box bilateral wall.The mutual inductor of this epoxy resin cast molding can prevent from casing is produced discharge, plays the good insulation performance effect, improves insulativity greatly; The ventilation window shutter of casing both sides can effectively improve mutual inductor radiating effect in the casing.
In the utility model, described mutual inductor skeleton adopts refractory ceramics to make.The mutual inductor that this refractory ceramics is made can prevent that the wiring of porcelain tower from apart from the nearer generation discharge of mutual inductor, can improve the insulation effect and the dielectric strength of mutual inductor.
The utlity model has following advantage:
1, owing to soak mutual inductor, can save a large amount of transformer oil, also avoid situations such as seepage, on fire, blast to take place simultaneously without transformer oil.
2, esy to use, safe and reliable, applied widely.

Embodiment
Referring to shown in Figure 1: a kind of substation transformer high pressure that is used for is surveyed the dry-type high-voltage electric metering box that electric energy metrical uses, it includes casing 4, mutual inductor 7, porcelain tower 1, mutual inductor in the casing 4 adopts one-body molded the making of epoxy resin casting, after wiring 3 soon connects mutual inductor 7, outside casting epoxy resin at mutual inductor 7, it is one-body molded that the interior mutual inductor of casing is enclosed in the epoxy resin, is provided with ventilation window shutter 5 in casing 4 two sides.The mutual inductor of this epoxy resin cast molding can prevent from casing is produced discharge, plays the good insulation performance effect, improves insulativity greatly; Casing 4 can adopt stainless steel material to make; The ventilation window shutter 5 of casing both sides can effectively improve the radiating effect of mutual inductors 7 in the casing 4.
In the utility model, described mutual inductor skeleton 6 adopts refractory ceramics to make.The mutual inductor that this refractory ceramics is made can prevent that the wiring of porcelain tower from apart from the nearer generation discharge of mutual inductor, can improve the insulation effect and the dielectric strength of mutual inductor.
Be mounted with 3 porcelain towers 1 on casing top, the wiring 2 of each porcelain tower is connected in the porcelain tower with mutual inductor wiring 3; The instrument box of this batch meter separates use with casing, and casing 4 is installed on the electric pole, and instrument box is installed in the bottom of electric pole, and the middle lead that connects is convenient to the measurement of tabling look-up like this.
Applicable outdoor 10 kilovolts of the utility model, installation and maintenance are convenient, long service life.
