Embodiment Construction

[0024] According to the accompanying drawings, it is explained as follows:

[0025] The device structure of the present invention includes: voltage paddle, current paddle, wiring screw, cover plate screw, installation fastening screw, metal groove, plastic insulating shell, incoming and outgoing wire terminals, terminal number, junction box cover plate.

[0026]The plastic insulating shell 1 is made of green insulating plastic and is divided into four voltage units and three current units. Each voltage unit corresponds to two sets of incoming and outgoing line terminals 2 and terminal number 3, and the current unit corresponds to four sets of incoming and outgoing lines. Terminal 2 and terminal number 3, the front of the incoming and outgoing line terminal 2 is fixed with the metal groove 5 on the back by the terminal screw 4 to complete the upper and lower communication of the current and voltage, and the left and right sides of the plastic insulating shell 1 have a pair of co...

Abstract

A multifunctional combined junction box comprises a voltage shift, a current shift, junction screws, cover plate screws, mounting fastening screws, a metal channel, a plastic insulating shell, incoming and outgoing terminals, terminal numbers, and a junction box cover plate. The junction box includes four voltage units and three current units, the voltage shift is mounted on a voltage unit, and the current shift is mounted on a current unit. The junction box can acquire real-time electric quantity uninterruptibly in real time in case of special transformer terminal or concentrator failure or meter replacement; the multifunctional combined junction box supports field inspection of an electricity meter; during meter replacement, the multifunctional combined junction box can meter the electric quantity in real time during meter replacement through connection with a field electricity metering instrument.

Description

technical field [0001] The invention relates to a multifunctional combined junction box, which belongs to the technical field of electric energy measurement such as collection and monitoring of electric energy information in electric power systems, handling of on-site faults of meters, and on-site calibration. Background technique [0002] As of the end of 2016, the State Grid Corporation has achieved full coverage and full collection of smart energy meters. At present, the special transformer and public transformer assessment and metering devices in the urban network use the special transformer terminal and the public transformer concentrator to collect various data and information. sent back to the master station. During on-site installation, the special transformer terminal and concentrator are installed together with the smart meter. In order to reduce customer power outages in the event of a failure, a three-phase combined junction box is generally installed in the spe...
