Abstract
The utility model discloses a power output current transformer which is applied to an electricity-stealing-preventing electronic type electric energy meter. The power output current transformer comprises a primary coil and a secondary coil, wherein the primary coil comprises an insulating layer, an iron core, an enameled wire and two secondary output lead wires, wherein the iron core is wrapped inside the insulating layer and made of iron-base nanocrystalline materials, and the enameled wire is wound outside the iron core. The primary coil comprises a live line and a zero line. A primary lead line penetrates through a center hole of the secondary coil one turn, and two ends of the live line and two ends of the zero line are provided with connecting pieces. The primary lead line (the live line or the zero line) penetrates through a center hole of the transformer one turn, and the iron core is made of the iron-base nanocrystalline materials, so the power output current transformer is small in size, easy to manufacture, low in cost and convenient to install and use. The end of the primary lead line is provided with a lug plate so as to be easily connected with a wire of a circuit to be detected when used, and the power output current transformer is convenient.
Description
Technical field
The utility model relates to a kind of power output current transformer that is applied in the anti-electricity-theft electronic electric energy meter.
Background technology
Existing electronic electric energy meter all requires anti-stealing electricity function, but existing power output current transformer half adopt silicon steel material as iron core, Live line Zero line all will pass its centre bore at least 2 circles, output just can reach the requirement of electric energy meter supply module, the copper material cost that consumes can be quite high, and cause the volume of electric energy meter bigger.
Summary of the invention
Technical problem to be solved in the utility model provides the less power output current transformer that is used for anti-electricity-theft electronic electric energy meter of a kind of volume, and its Live line Zero line only passes current transformer centre bore 1 circle, and overall structure is fairly simple, and is easy to use.
The utility model adopts following technical scheme: a kind of power output current transformer, its key technology is: it comprises primary coil and secondary coil, and described secondary coil comprises insulating barrier, is wrapped in the iron core of the iron based nano crystal material of insulating barrier inside, around enamelled wire and two secondary output leads of iron core outside;
Described primary coil is live wire and zero line, and described elementary lead-in wire passes centre bore 1 circle of secondary coil, and the two ends of live wire and zero line are equipped with brace.
Preferably, above-mentioned insulating barrier is formed by electric insulation PVC band, oil paint silk fabric or other wrapped with insulation.
Above-mentioned live wire, zero line are copper braid, multiply annealed copper wire or sub-thread rigid line.
The beneficial effect that adopts technique scheme to produce is: the elementary lead-in wire of the utility model (Live line Zero line) only passes instrument transformer centre bore 1 circle, and iron core is the iron based nano crystal material, and overall volume is very little, is easy to make, and cost is low, and is easy to install; The termination of elementary lead-in wire is provided with lug plate, is connected with the lead of circuit under test easily during use, and is convenient.
