Embodiment Construction
[0021] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some, not all, embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.
[0022] A fully automatic intelligent fee control metering device, such as figure 1 As shown, it includes a metering control unit 1 and a combined transformer 2 with a switch. The metering control unit 1 is connected to the combined transformer 2 with a switch. The metering control unit 1 is connected to a background system 3 . The background system 3 can monitor the commissioning status of the fee control device in real time, and read the basic information of ...

The invention belongs to the technical field of power high-voltage user distribution network power supply equipment, and particularly relates to a full-automatic intelligent cost control metering device which comprises a metering control unit and a combined mutual inductor with a switch. The metering control unit is connected with the combined mutual inductor with the switch through an interface,and the metering control unit is connected with a background system. In the invention, functions of the device are optimized, the metering control unit is integrally installed in one shell, interfacesand internal wiring are reserved, detection is completed in a workshop, cables are led out of the combined mutual inductor with the switch, and only the interfaces need to be connected during on-siteinstallation so that the device is simple, convenient, safe and reliable. A phase sequence automatic reverse switching device is added, after an intelligent high-voltage electronic dial controller receives a phase sequence reverse connection signal, a phase sequence automatic reverse switching device is controlled to act, phase sequence correct connection is completed, manual participation is notneeded, and the phase sequence reverse connection automatic correction function is completely achieved. The device is used for metering and controlling the electric charge.
Description
technical field [0001] The invention belongs to the technical field of electric high-voltage user distribution network power supply equipment, and in particular relates to a fully automatic intelligent fee control metering device. Background technique [0002] During the installation and wiring of the existing metering meters, 1. There will be 1> the phase sequence label is unclear, resulting in wiring errors; 2> when the phase sequence is reversed, it is easy to short-circuit and cause transformer failure when reversing the line; 3> due to wiring Wiring errors due to unclear principles; 4> Power on when the meter is not connected, and errors that are more serious than incorrect wiring occur. In severe cases, the transformer will explode. 2. Due to factors such as changes in the primary line load, the primary phase sequence changes and the secondary phase sequence changes, resulting in inaccurate billing or loss of electricity billing. [0003] The application o...
