Problems solved by technology

[0004] 1. Restrict the intensive management of power supply enterprises: the installation of each metering cabinet is a construction site, which requires the participation of many personnel and the cooperation of construction enterprises and production enterprises. Intensive management is not applicable, and the efficiency is low and the construction time is long;
[0005] 2. Seriously affect the establishment of the electric energy measurement quality management system of power grid enterprises: the measurement components of the current measurement cabinet are transported to the construction site in parts, resulting in an open circuit in the measurement management link; and the on-site installation method is easily affected by the construction environment and personnel , causing an error in the metering device
[0009] Because the produced electric energy metering cabinets (boxes) leave the factory in the form of semi-finished products (without installing metering components), the remaining workload is completed by the power supply company, which often results in unclear division of work interfaces

Embodiment 1

[0035] Such as figure 1 As shown, a modular electric energy metering device includes a main body 1 and a metering unit 2. The metering unit 2 includes a metering frame 21 and a metering module 22. The metering frame 21 is installed in the body 1. The metering module 22 is installed in the metering frame 21, wherein: the metering unit 2 can be disassembled and installed from the main body 1 as a whole.

[0036] Such as Figure 2~4 As shown, three upper frame busbars 211 and three lower frame busbars 212 corresponding to the positions are respectively arranged on the top surface and the bottom surface of the metering frame 21, and the upper frame busbars 211 and the lower frame busbars 212 are all A part is inside the metering frame 21, and a part protrudes out of the metering frame 21.

[0037] Such as figure 1 , 5 As shown, the metering module 22 is provided with three module busbars 221, and the ends of the upper frame busbar 211, the lower frame busbar 212 and the module...

Embodiment 2

[0044] Compared with the embodiment, the difference of this embodiment is that two sets of mutual inductance coils and electric meters are installed in the metering module, and the electricity consumption of two electricity prices can be measured in one electric energy metering device. For example, some enterprise users can use An energy metering device measures industrial and residential electricity consumption.

[0045] According to the difference of the electric energy meter, the junction box and the cable, the skeleton 222 in this example can also be a square shape, or a king shape, or other other shapes suitable for installing the electric energy meter, the junction box and the cable.

[0046]With this technical solution, the manufacturer of electric energy metering cabinets can install the metering frame on the body of the metering cabinet and transport it to the construction site as a whole. The power grid company can assemble the metering current transformer, electric e...

Abstract

The invention discloses a modular electric energy metering device. The device comprises a body and a metering unit. The metering unit comprises a metering framework and a metering module. The metering framework is installed in the body. The metering module is installed in the metering framework. The metering unit can be integrally dismounted from and installed on the body. The metering module comprises a skeleton, a junction box and an electric energy instrument installing hole. The junction box and the electric energy instrument installing hole are arranged on the skeleton. A module busbar is connected to the skeleton through an insulator. The skeleton is provided with a metering current transformer installing hole. By using the technical scheme, a power supply enterprise can realize intensive management, a power grid enterprise can establish a perfect electric energy metering quality management system, a construction enterprise only needs to go through the formalities in the power supply enterprise for one time, a work interface with the power grid enterprise is clearly divided and the three parties have no cross operation.

Description

technical field [0001] The invention relates to the field of power distribution equipment, in particular to a modular electric energy metering device. Background technique [0002] With the progress and deepening of the reform of the power enterprise system, the assessment of economic benefits is becoming more and more important, and an important part of it is to ensure the accuracy and reliability of electric energy metering devices. Nowadays, the safety and accuracy of electric energy metering components (transformers, electric meters, etc.) have reached a high level, but the installation process of electric energy metering devices is complicated: first, the manufacturer of electric energy metering devices transports the electric energy metering cabinets without metering elements to After the installation site, and after the intermediate acceptance of the power receiving project, the construction company will go to the local power grid company to go through the relevant pr...
