Abstract

The invention relates to a multifunctional three-phase four-wire charge control meter which comprises a bottom shell, a vacuum bubble mounted at the upper part of the bottom shell, and a tripping mechanism arranged in the middle of the bottom shell. The meter is characterized in that a connecting plate is arranged below the vacuum bubble; a positioning plate is arranged below the connecting plate;an energy storage connecting seat plate is arranged below the positioning plate; a left energy storage guide sleeve, a right energy storage guide sleeve and a middle energy storage guide sleeve are arranged between the energy storage connecting seat plate and the positioning plate; the energy storage guide sleeves are mounted on the energy storage connecting seat plate; each energy storage guidesleeve is sleeved with an energy storage spring, an energy storage guide shaft is arranged in each energy storage guide sleeve, the upper end of each energy storage guide shaft penetrates through thepositioning plate to be connected with the connecting plate, the lower end of each energy storage guide shaft penetrates through the energy storage connecting seat plate, and the cost control meter can meter electric energy and can also achieve short-circuit, overload, electric leakage, phase loss, overvoltage and undervoltage protection.

Description

technical field [0001] The invention belongs to the technical field of electrical equipment, and in particular relates to a multifunctional three-phase four-wire toll control meter. Background technique [0002] At present, the three-phase four-wire fee control meter in the market is implemented in the form of a combination of a three-phase four-wire electric energy meter and a three-phase four-wire residual current circuit breaker. On-off function. This method takes up a lot of space, is cumbersome to install, has a single function for a single device, and has limitations in application. [0003] Therefore, in order to fill the gap in the market and realize intelligent grid management, simplify the installation of electric meter equipment and reduce investment costs, a multifunctional three-phase four-wire tariff control meter integrating electric energy metering and residual current circuit breaker functions was developed and designed. Contents of the invention [0004...
