The first switch device is a breaker.
The second switch device is a band undervoltage tripping breaker.
3rd switching device is a breaker.
The load switching unit is a disconnecting switch.
The power information acquisition terminal, including controller, and the network transmission module being connected with controller;It is described to use Power information acquisition terminal carries out spatial load forecasting, electricity charge control and information gathering to user power utilization information and uploaded.
The power information acquisition terminal is identical with generated energy electric energy meter size, and with generated energy electric energy metrical The reserved COM1 of table is connected.
The material of the casing is stainless steel.
Beneficial effects of the present invention are:
(1) electric energy meter possess electric current and information of voltage collection, realize to generated energy, electricity volume, off line electricity and The real-time collection of station-service electric quantity data and normality monitoring;
(2) gauge table collection information is respectively connected to administration of power networks department and acquiring electric energy information system of photovoltaic generation administrative department System, foundation is subsidized as electrical energy metering and electricity price;User can be monitored in real time to be incorporated into the power networks situation, related data is preserved, and checked Grid-connected failure;
(3) present invention will be generated electricity, grid-connected, lower network metering and control device are entirely encapsulated in same cabinet, so as to possess Anti-electricity-theft in complete meaning automatically controls performance.
