Metering handcart convenient to overhaul

The metering handcart comprises a handcart body, a voltage transformer and a current transformer are connected to an installation plate of the handcart body, a fusion tube is connected between the voltage transformer and the current transformer, and rectangular clamping holes in one-to-one correspondence with the four corners of a backboard of the voltage transformer are formed in the installation plate. An L-shaped clamping piece capable of being matched with the clamping hole is connected to the voltage transformer back plate, and the vertical portion of the clamping piece can penetrate through the clamping hole so that the transverse flat portion of the clamping piece can be kept in the clamping hole. According to the metering handcart convenient to overhaul, the operation of connecting and fixing the voltage transformer on the mounting plate is simplified, and an operator can conveniently and quickly disassemble and assemble the voltage transformer for overhaul so as to quickly restore power supply. 本实用新型
