Embodiment
To describe technology contents of the present utility model, the objects and the effects in detail, below in conjunction with embodiment and match somebody with somebody
Accompanying drawing is closed to be explained.
It refer to Fig. 2, a kind of solid insulation withdraw-type scale car that the utility model is provided, including horizontally disposed chassis
10 are provided with electric energy meter 21, the installation with the installing plate 20 for being vertically arranged in chassis upper surface, the side of the installing plate
The opposite side of plate is provided with current transformer 22 and voltage transformer 23；The electric energy meter 21 respectively with current transformer 22 and
Voltage transformer 23 is directly connected to；
The current transformer 22 is located at the underface of voltage transformer 23, and the current transformer 22 is provided with insulator
221st, connecting copper bar 222, tactile wall 223 and fuse 224；One end of the insulator 221 is fixed on current transformer 22, separately
One end is fixedly connected with connecting copper bar 222；The tactile wall 223 is fixed in connecting copper bar 222；Described one end of fuse 224 is consolidated
It is scheduled in connecting copper bar 222 and is connected with current transformer 22, the other end is connected with voltage transformer 23.
