Abstract
The invention provides a metering box, a ground wire hitching method of the metering box, and a replacement method of a current transformer of the metering box. The metering box comprises a meter, multiple current transformers electrically connected with the meter, multiple input cables in one-to-one correspondence and in electrical connection with the input ends of the multiple current transformers, and multiple protective sleeves, wherein each input cable is provided with a first stripping port formed by peeling an insulation layer, and the first stripping port of each input cable is detachably provided with a protective sleeve. When a ground wire needs to be hitched to the input ends of the current transformers, such as when the current transformers in the metering box are replaced, the ground wire can be directly connected with an exposed metal wire at the first stripping port, such that what is needed is only to turn off the knife switches at the input ends of the transformers rather than breaking a high voltage drop fuse at the input ends of a transformer, thus the operation on the high voltage drop fuse is reduced, and the labor intensity of the work personnel is also reduced.
