Abstract

The invention discloses a junction box used for safe arc extinguishing of a metering secondary circuit, and relates to the technical field of power equipment; the junction box comprises a box body, an inflow-side current terminal, an outflow-side current terminal, a rotary knob, The arc-extinguishing grid piece, the contact connecting piece and the movable rod on the turning button, the contact connecting piece is electrically connected with the current terminal on the outflow side, the arc-extinguishing grid piece is located next to the contact connecting piece, and one end of the movable rod is connected with the turning button, and the movable rod is connected to the turning button. The other end of the rod is the free end, which is located between the arc-extinguishing grid and the contact connecting piece. The movable rod is in sliding contact with the current terminal on the inflow side and is electrically connected. The rotating knob drives the movable rod to slide on the current terminal on the inflow side. The free end of the rod is overlapped with the contact connecting piece and electrically connected or the free end is separated from the contact connecting piece and is close to the arc chute; Arc quenching grid, contact connecting piece and movable rod, etc., realize the safety of meter installation and electricity connection.

Description

technical field [0001] The invention relates to the technical field of electric power equipment, in particular to a junction box used for safe arc extinguishing of a metering secondary circuit. Background technique [0002] In the power marketing work, when the meter installation and power connection team conducts troubleshooting or replaces the electric energy meter and concentrator, it is necessary to disconnect the voltage terminal and short-sealed current terminal in the secondary circuit first to ensure that there is no voltage in the secondary circuit. After the current is adjusted, start a series of specific tasks such as removing the various terminals at the end of the electric energy meter or the concentrator. [0003] In the opening and closing of the voltage and current connecting pieces, in addition to the need to pay attention to the insulation of tools and people to prevent electric shock, it is also necessary to pay attention to prevent the generation of arcs ...
