Abstract
The utility model discloses an indoor dry-type voltage transformer which comprises a body, a mounting base plate, an iron core and a winding framework, wherein the iron core is a seamless iron core, a shielding insulating layer is wound around the iron core, and a surplus winding, a secondary winding and a primary winding are arranged outside the winding framework in sequence. A transformer body is made of epoxy resin and is poured into an integral structure, a primary insert nut is connected with the primary winding, a secondary insert nut is externally connected with the second winding, the mounting base plate is fixedly connected to the bottom end of the transformer body, a mounting insert nut is arranged on the mounting base plate, and a polyester film compound capacitor insulating layer is arranged between the first winding and the second winding. According to the indoor dry-type voltage transformer, a seamless iron core structure is adopted, the insulating layer is arranged between the first winding and the second winding, overvoltage times are increased effectively, and anti-saturation performance is strong. Meanwhile, the body is of a full closed structure, and therefore the indoor dry-type voltage transformer has the advantages of maintenance-free and all condition. The indoor dry-type voltage transformer is capacitive in loading condition, the iron core is unsaturated, accordingly the occurrence of resonance is avoided effectively, and operation is safe.
Description
Technical field
The utility model relates to a kind of voltage transformer, relates in particular to a kind of indoor dry-type voltage inductor.
Background technology
Indoor dry-type voltage inductor is to change its equipment as High-Voltage Electrical Appliances intelligence control circuit power supply as measuring voltage and high-low pressure in the High-Voltage Electrical Appliances, indoor dry-type transformer volume commonly used is big, do not have seal approach, restriction because of structure, it is big partial discharge quantity to occur, it is big to sharpen magnetoelectricity stream and no-load loss, the characteristic linearity is bad, the anti-saturation ability, under unexpected folding lock and circuit single-line ground situation, produce ferro resonance easily and cause overvoltage, jeopardize power grid security, and when circuit generation resonance, cause the iron core magnetic flux saturated easily, cause instrument transformer to burn.
The utility model content
At above-mentioned defective, the utility model provides a kind of indoor dry-type voltage inductor, anti-overvoltage carefully, the anti-saturation ability is strong, is capacitive under the loading condition, resonance not, security of operation.
To achieve these goals, the technical scheme that the utility model adopts is: a kind of indoor dry-type voltage inductor, comprise the transformer body, base plate is installed, iron core and winding skeleton, described iron core is seamless iron core, the iron core outside is wound with shield dielectric layer, be wound with the residue winding successively in winding skeleton outside, secondary winding and a winding, described transformer body adopts poured with epoxy resin to become an integrally-built pour mass, female and the secondary embedding mother of an embedding is set on the transformer body, an embedding is female to be connected with a winding, the secondary embedding is female to be connected with secondary winding, base plate is installed is fixedly connected on transformer body bottom, base plate is installed is provided with installation embedding mother.
Further, the interlayer of a described winding and secondary winding is provided with polyester film recombiner condenser paper insulation layer.
Further, described secondary embedding mother places in the secondary capping that transparent material makes, and described transparent material is polymethyl methacrylate.
Indoor dry-type voltage inductor of the present utility model adopts seamless core structure, winding and secondary winding layer insulation, effectively improved the overvoltage multiple, the anti-saturation ability is strong, and the transformer body adopts the cast integral structure, full-closed structure, have characteristics non-maintaining, full operating mode, be capacitive under the loading condition, iron core is unsaturated, the generation that resonance shakes, security of operation have effectively been prevented in the line.
