The invention discloses an experimental three-phase four-wire electricity meter junction box, which comprises a box body and a winding mechanism, wherein a door body is fixed on one side of the box body; a glass plate is embedded into the door body; an electrode plastic shell is arranged on one side of the box body; a connecting mechanism is arranged in the electrode plastic shell; the winding mechanism is arranged inside the box body; a base is arranged inside the winding mechanism; the base is fixedly connected to the box body; and a groove is embedded into the base. According to the experimental three-phase four-wire electricity meter junction box, a special measuring hole structure is adopted for the first time, so that the experimental three-phase four-wire junction box is connected to an external test plug more safely; the experimental three-phase four-wire electricity meter junction box is made of a high-quality PPS plastic material and a metal copper material and has higher corrosion resistance and oxidation resistance and excellent electrical performance; and a test hole structure penetrating through an external insulating plate is innovatively designed, so that a reliableconnection with an external testing equipment plug without disassembling the external insulating plate is realized.
Description
technical field [0001] The invention relates to the technical field of fixtures, in particular to an experimental three-phase four-wire electric meter junction box. Background technique [0002] The distribution network power supply area of the power system often causes high loss and negative loss problems in the station area due to reasons such as "lost households", "cross-station" and "electricity theft". For the investigation of high-loss station areas, the method of checking the phase of the station area identification instrument is mainly adopted. The three-phase four-wire meter is mainly coupled and connected to the collection terminal concentrator through the junction box. The wiring electrodes of the current three-phase four-wire meter junction box The layout is tight and there are no special measurement points for testing. The alligator clips of the platform identification instrument cannot be reliably connected to the phases, and accidents such as phase-to-phase ...
