Ring main unit built-in metering system data transmission method

Abstract

The present invention discloses a ring main unit built-in metering system data transmission method. The method is configured to transmit text data and multimedia data, employs three different mode consisting of a high-speed mode, a carrier mode and a terminal query mode to perform data transmission, and a targeted data compression method is designed for the carrier mode; and the query mode performs metering module data query through a reserved wired interface. The ring main unit built-in metering system data transmission method is rapid and convenient to install, save the cost, is comprehensive in function, employs the built-in metering design with no need for separated design of a metering cabinet, and is convenient and rapid; and moreover, the three different transmission modes are veryhigh in adaptation and can be widely applied to places with incomplete base installations.

Description

technical field [0001] The invention belongs to a power supply metering system in the field of high-voltage power supply, and in particular relates to a data transmission method of a built-in metering system of a ring network cabinet. Background technique [0002] At present, the "cable into the ground" of the urban power grid has become the mainstream, the 10 kV line of the distribution network goes deep into the load center, and the outdoor ring main unit is widely used, and the handle switch is located in the outdoor ring main unit. In order to achieve lean management of line loss, complete the goal of refinement of medium and low voltage line loss management and control of the State Grid, and promote the management of 10 kV sub-lines, it is necessary to add metering devices to the ring main unit to realize the 10 kV handle switch of the urban distribution network bidirectional metering. [0003] Most of the current ring network cabinets, especially those involving old u...

Problems solved by technology

[0003] Most of the current ring network cabinets, especially those involving old urban areas and remote areas, were erected earlier, and are only equipped with incoming and outgoing cabinets, but not equipped with metering cabinets, which leads to difficulties in power metering in some areas. Urgent need to revamp these RMUs

[0004] In addition, due to the remote area to which some ring network cabinets belong, communication is difficult, and the signal of ordinary communication methods is difficult to cover, and the communication bandwidth of the power carrier is not high due to its own problems.

[0005] In addition, if a metering cabinet is added to the transformation of the ring network cabinet, the workload will be greatly increased, which will greatly increase the cost
