Abstract
The utility model discloses a kind of convenient type metering handcart, comprise handcart skeleton, current transformer, contact arm, fuse and voltage transformer, described handcart skeleton is combined by chassis vehicle and mounting panel; Described current transformer and contact arm are cast for integral structure, and at right angle setting is on mounting panel; Described voltage transformer is arranged on chassis vehicle, and voltage transformer upper end is provided with fuse, and fuse is connected with the contact arm of the side of being located thereon; Position relative with current transformer on described mounting panel is provided with gauge table, between described current transformer and voltage transformer, links together by cable.The utility model, in the limited space of breaker chamber, considering, on the electric clearance of all directions and the basis of creepage distance, the relatively large current transformer of volume to be installed on the top of handcart pedestal, can obtain more accurately metering handcart and measures.
Description
Technical field
The utility model belongs to metering handcart field, refers to especially a kind of convenient type metering handcart.
Background technology
In existing 12KV ac metal closing switch gear, metering handcart is the critical elements of switch cubicle, current transformer and voltage transformer are arranged on a table frame simultaneously, driven by chassis vehicle, its effect is that current transformer, voltage transformer, fuse and the measuring instrument case etc. of metering use are all integrated on a dolly, can entirety pull out or push switchgear, the quick and safety while being conducive to inspection and maintenance.
Existing metering handcart structure generally includes chassis vehicle, be located at the handcart pedestal on chassis vehicle, be separately fixed at the instrument box on handcart pedestal, voltage transformer, current transformer and fuse etc., wherein: described current transformer is arranged on the bottom of handcart pedestal short transverse, described voltage transformer is arranged on the top of handcart pedestal short transverse, adopt this mounting means, because the relatively large current transformer of volume is arranged on the bottom of handcart pedestal short transverse, in the time of metering, do not comprise voltage transformer, the power loss of fuse, thereby can there is error in dipping, the accuracy of impact metering.
For this reason, the applicant has done actively and effectively to explore, and has finally found the technical scheme addressing the above problem, and has taked under strict secrecy provision, to the experiment proved that it is practicable.
Utility model content
The purpose of this utility model is to provide that a kind of volume is little, floor space is little, can makes the convenient type metering handcart of the current transformer that metering more accurate top band and contact arm are integral type.
A kind of convenient type metering handcart described in the utility model, comprises handcart skeleton, current transformer, contact arm, fuse and voltage transformer, and described handcart skeleton is combined by chassis vehicle and mounting panel; Described current transformer and contact arm are cast for integral structure, and at right angle setting is on mounting panel; Described voltage transformer is arranged on chassis vehicle, and voltage transformer upper end is provided with fuse, and fuse is connected with the contact arm of the side of being located thereon; Position relative with current transformer on described mounting panel is provided with gauge table, between described current transformer and voltage transformer, links together by cable.
Further improve, on described mounting panel, terminal box is installed.
Further improve, described terminal box is positioned at the below of gauge table.
Further improve, the high order end of described chassis vehicle is provided with guide plate.
The beneficial effects of the utility model are:
Compared with prior art, the utility model is in the limited space of breaker chamber, considering, on the electric clearance of all directions and the basis of creepage distance, the relatively large current transformer of volume to be installed on the top of handcart pedestal, making metering handcart can obtain metering more accurately; In addition, described current transformer and contact arm are cast for integral structure, are the designs of a kind of new structure, saved space, have reduced the volume of handcart.
Brief description of the drawings
Fig. 1 is structural representation of the present utility model.
Embodiment
As shown in Figure 1, a kind of convenient type metering handcart described in the utility model, comprises handcart skeleton, current transformer 4, contact arm 5, fuse 6 and voltage transformer 7, and described handcart skeleton is combined by chassis vehicle 9 and mounting panel 3; Described current transformer 4 is cast for integral structure with contact arm 5, and at right angle setting is on mounting panel 3; Described voltage transformer 7 is arranged on chassis vehicle 9, and voltage transformer 7 upper ends are provided with fuse 6, and fuse 6 is connected with the contact arm 5 of the side of being located thereon; On described mounting panel 9, the position relative with current transformer 4 is provided with gauge table 2, between described current transformer 4 and voltage transformer 7, links together by cable.
On described mounting panel 3, terminal box 1 is installed, described terminal box 1 is positioned at the below of gauge table 2.
The high order end of described chassis vehicle 9 is provided with guide plate 8.
The utility model provides a kind of convenient type metering handcart; the above is only preferred implementation method of the present utility model; should be understood that; for those skilled in the art; do not departing under the prerequisite of the utility model principle; can also make some improvement, these improve and also should be considered as protection range of the present utility model.
