Insulating cover is provided with outside described bus connecting piece.
Described cabinet is provided with panel, and the corresponding electric energy meter place of panel is provided with observation window.
Dividing plate is provided with between described metering handcart and power lug.
The bottom of described metering handcart is provided with four rolling.
The utility model adopts above technical scheme, and adopt handcart-type structure, be arranged on metering handcart by D.C mutual-inductor and voltage transformer, metering handcart can pull out cabinet and overhaul outward, convenient and practical; And solid insulating layer is set on the surface of the electric conductor such as contact and conductive contact arm, make these product insulation property better, volume is less.The utility model achieves miniaturization, substantially increase equipment applicability, can perfect supporting miniaturized solid insulation switch cabinet, achieve miniaturized solid insulation switch cabinet and normally measure, power, for the electric energy metrical meeting State Grid Corporation of China, significant.
Accompanying drawing explanation
Below in conjunction with the drawings and specific embodiments, the utility model is described in further details;
The front view of a kind of miniaturized handcart-type solid insulation metering cabinet of Fig. 1 the utility model;
The cutaway view of the side-looking of a kind of miniaturized handcart-type solid insulation metering cabinet of Fig. 2 the utility model.
Embodiment
As shown in Figure 1 or 2, the utility model comprises cabinet 1, metering handcart 2, cabinet 1 is provided with panel, metering handcart 2 is movably arranged in cabinet 1, metering handcart 2 is provided with electric energy meter 8 towards panel 12 side, metering handcart 2 opposite side upper end is provided with voltage transformer 4 side by side, the lower end of metering handcart 2 opposite side is provided with current transformer 3, voltage transformer 4 summation current transformer 3 is connected by bus connecting piece 5, bus connecting piece 5 outer surface is coated with solid insulating layer, current transformer 3 comprises upper binding head and lower union joint, the upper binding head of current transformer 3 and lower union joint are separately installed with the conductive contact arm 7 of Surface coating solid insulating layer, conductive contact arm 7 is flexibly connected with the external insulation contact 11 be provided with inside cabinet 1, the power lug 13 that external insulation contact 11 is provided with by wire loop 10 and cabinet 1 inside front is connected.
Further, insulating cover 6 is provided with outside described bus connecting piece 5.
Further, described panel 13 corresponding electric energy meter 8 place is provided with observation window 14.
Further, dividing plate 9 is provided with between described metering handcart 2 and power lug 13.
Further, the bottom of described metering handcart 2 is provided with four rolling 21.
Electric energy meter 8, voltage transformer 4 summation current transformer 3 are co-located on metering handcart 2 by the utility model, and such measurement loop directly connects middle without the need to transition, improves the reliability of metering link circuit.
Moreover metering handcart 2 of the present utility model coordinates the four rolling be provided with bottom it by specific purpose tool, can shift out cabinet 1, after leaving cabinet 1, metering handcart 2 is completely not charged, very safe for repair and maintenance, and space is comparatively large outside to leave cabinet 1, inspection and maintenance is all very convenient.Only electric energy meter 8 is read by observation window 14 when panel 13 on cabinet 1 is not opened, cannot movable metering handcart 2.After only having unlatching, just metering handcart 2 can be moved to link position or shift out outside cabinet.When metering handcart 2 moves on to link position, the conductive contact arm 7 of metering handcart 2 is connected with the external insulation contact 11 on cabinet 1, and now constitute complete conductive loop, metering cabinet normally works.
In addition, metering handcart 2 of the present utility model is different from traditional approach, current transformer 3 is arranged on the below of voltage transformer 4, and conductive contact arm 7 position on such metering handcart 2 is past be have dropped, the external insulation contact 11 also past decline that cabinet 1 is supporting.The model with fuse installing space selected by voltage transformer 4, fuse is arranged on instrument transformer inside, its upper end does not have exposed electrified body like this, do not need as the instrument transformer of common employing, ensure that electric equipment compartment is apart from 125mm over the ground, therefore the dividing plate 9 on cabinet 1 can, toward declining, keep more than 30mm spacing just much of that with voltage transformer 4.Cabinet 1 of the present utility model highly greatly reduces, and cabinet 1 still has sufficient space to be convenient to the connection of galvanic circle 10 simultaneously.Surface, galvanic circle 10 is also coated with solid insulating layer, and the electric equipment compartment required for such galvanic circle 10 is apart from being also reduced into 80mm from exposed electrified body electric equipment compartment apart from 125mm, and cabinet profile can reduce further, achieves miniaturization.Highly finally be reduced to 1400mm, achieved real meaning miniaturized, can support the use with the solid insulation ring main unit of miniaturization.
The utility model adopts above technical scheme, and adopt handcart-type structure, be arranged on metering handcart by D.C mutual-inductor and voltage transformer, metering handcart can pull out cabinet and overhaul outward, convenient and practical; And solid insulating layer is set on the surface of the electric conductor such as contact and conductive contact arm, make these product insulation property better, volume is less.
