Abstract
The utility model discloses a high-voltage metering handcart which comprises a voltage transformer (2), a fusible core (4), a conductive block (5) and a current transformer (10), wherein the voltage transformer is mounted perpendicularly on a voltage transformer mounting plate (1); the current transformer (10) is mounted perpendicularly on a current transformer mounting plate (11); and the voltage transformer (2) is mounted above the current transformer (10). The high-voltage metering handcart adopting the technical scheme has the advantages of simple structure, reasonable design, and convenience for manufacturing and installation, reduces the manufacturing cost and lowers the contact height; and the handcart main body can be driven reposefully to enter the working position from the test position so long as a chassis screw rod is rocked through a handle, thereby ensuring that the movable contact and the fixed contact of the handcart are reliably jointed.
