Abstract

The invention provides a multifunctional joint junction box for electric energy metering. The multifunctional joint junction box comprises a cover, a base, a base cover and a plug-in tooling, whereinthe base is provided with a current connection terminal and a voltage connection terminal; the current connection terminal is provided with a pressing type detection switch and a plug-in type meter change switch; the current connection terminal is also provided with current connection contacts for connection with a field calibrator; the voltage connection terminal is provided with a pressing typevoltage switch; and the voltage connection terminal is also provided with voltage connection contacts for connection with the field calibrator. The field calibrator can be seamlessly connected into atest circuit by setting the pressing type detection switch, the pressing type voltage switch and a pin-type meter-change switch, and fixing the detection switch, the voltage switch and the meter-change switch to the connection terminal on the base, that is, to a copper bar on the base, wherein the detection switch and the voltage switch can switch the current and voltage circuits during meter checking; the meter-change switch is used to replace the electric energy meter and perform short-circuit operation on an electric circuit.

Description

technical field [0001] The invention relates to the technical field of combined junction boxes, in particular to a multifunctional combined junction box for electric energy metering. Background technique [0002] At present, the joint junction box for electric energy measurement is an important part of the secondary circuit of the metering. Its function is to connect the secondary line from the transformer to the terminal of the electric energy meter through the terminal of the joint junction box in series and parallel. By changing the junction box The position of the upper paddle changes the on-off state of the test circuit, which provides necessary conditions for the on-site calibration of the metering device, power inspection and replacement of the electric energy meter. [0003] However, the existing combined junction box for electric energy metering has the following problems in the use process: in the normal working state, the voltage paddle in the junction box is in t...
