Abstract
The utility model provides a high-voltage arc preventing power transformer. The high-voltage arc preventing power transformer comprises a wire winding skeleton. A plurality of coil lead pins are arranged on the wire winding skeleton. An insulating partition board is arranged in a wire winding groove of the wire winding skeleton. Primary windings and secondary windings are wound on the two sides of the insulating partition board respectively. The primary windings and the secondary windings are connected with the lead pins on the two sides respectively. The primary windings and the secondary windings are coated with insulating layers. The insulating layer outside the primary windings is made of rubber, or polytef reinforcement insulating materials or rubber and polytef composite reinforcement insulating materials. According to the high-voltage arc preventing power transformer, through arrangement of the insulating partition board, the wire winding groove becomes a separated double-groove structure, the primary windings and the secondary windings are reliably isolated, and accordingly the purpose of isolating high-voltage arc is achieved. Moreover, the heightened insulating partition board can well sink into a PCB when the transformer is assembled on the PCB, and consequently the purpose of completely isolating the primary windings and the secondary windings on the PCB is achieved.

Technical field
The utility model relates to power transformer technical field, particularly a kind of anti-high-voltage arc power transformer for intelligent electric meter.
Background technology
Existing power supply transformer primary and secondary coil windings is conventionally in the skeleton of same single winding slot, as shown in Fig. 1 ~ 3, between armature winding and secondary winding, can not reliably isolate, under wet environment high pressure conditions, easily produce arc through (see figure 8), the design that armature winding adopts general insulating tape 7 to insulate, make its to pin and pcb board air apart from deficiency, and produce, discharge, as shown in the original coil high-voltage arc origination point 5 in Fig. 3, and original transformer winding process adopts three-dimensional stacked system, the overall dimension that has increased whole transformer after winding stack is larger, can not meet existing market and assembling product be had to the demand of height dimension restriction.
Summary of the invention
Technical problem to be solved in the utility model is to provide a kind of anti-high-voltage arc power transformer, can reliably isolate armature winding and secondary winding, makes it under high pressure conditions, can not produce arc through between primary and secondary winding.Further, from structure, avoid coil to see through the interference of pcb board electric discharge.
For solving the problems of the technologies described above, the technical scheme that the utility model adopts is: a kind of anti-high-voltage arc power transformer, comprise bobbin, on bobbin, be provided with a plurality of coil lead pins, in the winding slot of bobbin, be provided with insulating barrier, armature winding and secondary winding are wound on respectively the both sides of insulating barrier, and armature winding is connected with the lead-in wire pin of both sides respectively with secondary winding, and armature winding and secondary winding are coated with insulating barrier.
The reinforced insulation material that insulating barrier employing rubber, polytetrafluoroethylene or rubber outside armature winding and polytetrafluoroethylene are compound.
Bobbin is pegged graft by coil lead pin and PCB circuit board, is also provided with the insulation board slot of pegging graft with insulating barrier on PCB circuit board.
The thickness of described insulating barrier is 0.8 ~ 1.2mm.
A kind of anti-high-voltage arc power transformer that the utility model provides, the insulating barrier by arranging, makes winding slot become the dual-slot structure of isolation, has isolated reliably armature winding and secondary winding, reaches the object of isolated high-voltage arc.Further, the insulating barrier of increasing can well sink in pcb board when transformer group installs to PCB, plays the object of fully isolating primary and secondary winding on pcb board.Transformer insulated intensity of the present utility model can reach 5000V AC, and in industry, the universal standard is 3750V AC, thereby can guarantee that transformer high-voltage state under the environment of various high temperature humidities is difficult for moist arc through.The utility model, in wire winding design, has changed the technique of primary and secondary winding stack coiling, has adopted the wire winding of winding isolated plane layout, has reached the object of dwindling winding coil overall dimension.After being subject to skeleton to sink in pcb board, the high-tension coil of armature winding is apart from pcb board apart from furthering impact, and armature winding adopts reinforced insulation material to isolate, and has avoided armature winding to see through the interference of pcb board electric discharge.
