According to the principle of " four unifications, convenient and efficients ", accelerate distributed photovoltaic power generation project and net spee, be within the flow time limit
Client completes grid-connected service.
But during grid-connected service, having one and comparing distinct issues is, because of inhabitant distribution formula photovoltaic generation
Project has certain requirement, or ground or roof or the water surface to equipment fabricating yard, therefore possesses the resident point of mounting condition
Small towns, rural area of the cloth photovoltaic generation project polydispersion in each county (area), business area under one's jurisdiction expands to each company of county.Although city,
Each business window of company of county has all carried out the grid-connected service of distributed photovoltaic in time, but enters after the construction stage, because batch meter is
Making is voluntarily invested by client, the batch meter that client provides has plenty of the transformation carried out on the basis of existing family electricity box, had
It is then that client voluntarily has made to order, material, size, reserved epitope, switchgear distribution etc. are relatively more chaotic, without unified technical requirements and configuration
Principle, quality can not also ensure, cause the batch meter of portions of client because the nothing measure of falling power transmission, the more low reason of configuration standard can not
By grid-connected Acceptance application, the service schedule of the grid-connected project of distributed photovoltaic is have impact on, is also easy to cause client to be discontented with.Therefore,
The standard of the batch meter of specification 380 (220) V distributed photovoltaic power generations, as current urgent problem.
The content of the invention

One terminal of gauge table is connected to load switching unit by second switch device;The generated energy electric energy meter and critical point
Another terminal of gauge table is connected to load by the 3rd switching device.
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.
