Abstract

The invention relates to a test-type watthour meter junction box. More than two conductive wiring devices are arranged in a box body and are mutually insulated; any one conductive wiring device comprises a watt-hour meter incoming end, an electric power circuit incoming end, a first electric conductor and a second electric conductor; in any conductive wiring device, the first electric conductor is isolated from the second electric conductor, a conductive connecting piece is arranged between the first electric conductor and the second electric conductor, and is provided with an operating position and a testing position, the conductive connecting piece in the operating position is connected with the first electric conductor and the second electric conductor simultaneously, the watt-hour meter incoming end is connected with a testing bolt, and watt-hour meter testing can be performed under the condition of powering on; and insulated positioning columns are arranged in a cover cap, and can ensure that all conductive connecting pieces can return to the operating state from the testing state. According to the invention, field on-load watthour meter correction and replacement are convenient, and working efficiency is greatly improved.

Description

Technical field: [0001] The invention relates to the electrical field, in particular to a watt-hour meter, in particular to a test-type watt-hour meter junction box. Background technique: [0002] In the prior art, the watt-hour meter junction box is used to realize the connection of the watt-hour meter. When repairing and checking the watt-hour meter, the junction box needs to be disconnected from the circuit, which reduces the work efficiency and cannot perform on-site meter calibration or meter replacement under load. At the same time, after the terminal is disassembled for maintenance and inspection, errors are prone to occur when it is reconnected to the working state. Invention content: [0003] The purpose of the present invention is to provide a test-type watt-hour meter junction box. The test-type watt-hour meter junction box solves the problem that the watt-hour meter junction box in the prior art cannot carry on-site meter calibration or meter replacement or wo...
