Abstract
An indoor semi-closed single-phase potential transformer relates to a potential transformer and is of an epoxy-resin-cast semi-closed structure. An iron core is formed by superposing silicon steel plates and of a semi-cast type. The lower part of a main body is provided with a secondary terminal box which is integrally cast. An A terminal at the upper part of the main body is of a single high-voltage insulating mainstay structure. An N terminal of a primary winding is positioned in the secondary terminal box. As the A terminal of the primary winding is of the single high-voltage insulating mainstay structure, the potential transformer has higher electrical performance and simple structure, and a production mould is also simple; therefore, quality control can be effectively carried out. Inaddition, a small amount of the epoxy resin is used, and the potential transformer has a small volume and reduces the cost.
Description
Technical field
The utility model relates to a kind of instrument transformer, refers more particularly to a kind of voltage transformer.
Background technology:
Indoor semiclosed single-phase potential transformer is the semi-enclosed product of poured with epoxy resin, iron core adopts the silicon steel sheet closed assembly to form, iron core half cast-type, be provided with the secondary connection box of cast one in the bottom of main body, secondary connection end S1, S2 are positioned at the secondary connection box, one time winding two ends turnover line is two High-Voltage Insulation corbelings, is respectively A, N end, and A end and N end are mutually at an angle.The shortcoming of this structure is: A end and N end adopt mutual High-Voltage Insulation corbeling at an angle, and structure is complicated, the production mould complexity, and the quality control difficulty, and the epoxy resin consumptive material is many, and volume is big etc.
The utility model content
The purpose of this utility model is the deficiency that overcomes prior art, and the indoor semiclosed single-phase potential transformer of a kind of easily manufactured, compact conformation, volume is little, cost is low easy-to-connect is provided.
The technical scheme that technical problem adopted that solves is:
Indoor semiclosed single-phase potential transformer is the semi-enclosed structure of poured with epoxy resin, iron core adopts the silicon steel sheet closed assembly to form, iron core half cast-type, be provided with the secondary connection box of cast one in the bottom of main body, the A end that it is characterized in that a winding is single High-Voltage Insulation corbeling, and the N end of a winding causes in the secondary connection box.
The beneficial effects of the utility model are: because the A of winding end is single High-Voltage Insulation corbeling, its electrical property strengthens, and is simple in structure, production mould is also simple complicated, can carry out quality control effectively, and the epoxy resin consumptive material is little, volume is little, reduces cost.
Description of drawings
Below in conjunction with drawings and Examples the utility model is further specified:
Fig. 1 is the front view of the utility model embodiment.
Among the figure 1, base plate 2, A end 3, main body 4, iron core 5, secondary connection box 6, N end
Embodiment:
As shown in Figure 1, the indoor semiclosed single-phase potential transformer of the utility model embodiment is the semi-enclosed product of poured with epoxy resin, iron core 4 adopts the silicon steel sheet closed assembly to form, iron core 4 half cast-types, be provided with the secondary connection box 5 of cast one in the bottom of main body 3, the A end 2 that the N end 6 of a secondary connection end and a winding is positioned at 5, windings of secondary connection box is single High-Voltage Insulation corbeling, main body 3 is the poured with epoxy resin structure, and the bottom surface of main body 3 is provided with base plate 1.Because the A of winding end 2 is single High-Voltage Insulation corbeling, change original A end and N end and adopted mutual High-Voltage Insulation corbeling at an angle, its electrical property strengthens, simple in structure, production mould is also simple complicated, can carry out quality control effectively, and the epoxy resin consumptive material is little, volume is little, reduces cost.
