The invention discloses a metering junction box. The metering junction box comprises a box body, a current wiring operation part and a voltage wiring operation part. The metering junction box can operate a first conductive terminal and a second conductive terminal of a current connection operation part and a voltage operation rod of a voltage wiring operation part outside the box body outside thebox body. A short circuit or an open circuit of a first current connecting piece and a second current connecting piece can be realized; and the open circuit or the short circuit of a first connectingsplit body and a second connecting split body is achieved, screws in the box body do not need to be disassembled in a whole process, operation is easy and convenient, a speed is high, operators can rapidly complete metering junction box wiring operation, and ammeter and terminal replacement efficiency is greatly improved.
Description
technical field [0001] The invention relates to the technical field of electric equipment, in particular to a metering junction box. Background technique [0002] In the operation and maintenance of power supply metering, before replacing the meter and terminal, it is necessary to operate the meter junction box to ensure that the two current wires in each phase inside the meter junction box are short-circuited and the voltage wires of each phase are disconnected. In the junction box of the prior art, when short-circuiting and disconnecting the current wire and the voltage wire, it is necessary to remove the panel covering the upper end of the junction box, and then unscrew the screws on the current wire and the voltage wire, and use the first metal sheet After connecting and shorting the two current wires, and removing the second metal connecting piece on the voltage wire to form an open circuit on the voltage wire, reinstall the screws and the panel. The meter junction box...
