Invensys MG Series inverter free trial application list released
Recently, the "Industry Free Trial of MG Inverter", which was highly concerned by the industry, took a successful completion in one month. Finally, five PV power station users were granted the qualification for trial application. They are: Shenyang Xidong Control Technology Co., Ltd., Wuhan Rixin Technology Lighting Co., Ltd., Hubei Yingli Green New Energy Co., Ltd., Jiangsu Aihe System Integration Engineering Co., Ltd., and Cixi Selep Photovoltaic Co., Ltd.
As the first in-vehicle photovoltaic grid-connected inverter with the smallest volume and highest conversion efficiency from Inventech, MG single-camera series is a new-generation photovoltaic string inverter developed by Inventronics for distributed home users. It is small and lightweight. , Easy installation and maintenance, high cost performance. At present, the series is mainly divided into two power sections of 1-3kw and 4-5kw. For the same power stage models, the MG single camera series combines the actual operation characteristics of the domestic power grid, in-depth software optimization, and better adaptability to the power grid; at the same time, the machine adapts to an ultra-wide voltage range, can accept extremely low starting voltages and achieve higher performance. The conversion efficiency (minimum starting voltage 50V); and MG single camera series can also be globally integrated management, support for portable mobile devices, and HMI optional; Invensys chose more reasonable components and thermal design on the hardware, Longer life.
In order to give back to domestic customers, Inventronics provides five new MG3KTL inverter products for free to the above 5 user experiences. The trial period is 6 months, and the trial period (August 1, 2016) will be returned to the machine by the deadline, and Submit no less than 1,000 trial reports by the 15th of the month. Inventronics will evaluate the trial report. In regards to the trial opinions and suggestions, Invitek will provide a wealth of gift rewards.

The principle of metal spinning process is to cover the processed metal blank (tube blank) on the mandrel, while the blank is pressed at the end of the mandrel by the tail, and rotates with the mandrel along the spindle, and the rotary wheel moves along the mandrel.
Generally speaking, light automatic spinning machines have structural advantages similar to ordinary lathes. However, in order to meet the requirements of the above spinning process, large spinning machines usually have the following 11 core advantages.
1. The automatic spinning machine bed, main shaft, and transmission system, rotating wheel frame, tailstock and other parts should have sufficient rigidity, and also have a heavier worktable, a thicker guide rail, and a thick wall bearing support And cabinets.
2. The horizontal and longitudinal feed mechanisms of the rotary frame are mostly driven by hydraulic transmission or a combination of mechanical and hydraulic pressure to generate sufficient spinning pressure and balance step-less speed regulation to meet process requirements.
3. Ordinary automatic spinning machines usually use one rotary wheel, but there are multiple auxiliary forming wheels (flanging wheel, curling wheel, etc.). The number of rotating wheels or rotating frame of the powerful automatic spinning machine is 2 to 3 (the general type is 2, and the cylindrical part spinning machine is mostly 2 to 3), and is symmetrical to the spindle axis. Balancing the radial force during spinning, reducing the bending deflection, deflection, and vibration of the spindle and core mold provides a prerequisite for improving the accuracy of spinning parts. This correspondingly requires the rotary wheel to have a higher horizontal (such as a special spinning machine for cylindrical parts) or a longitudinal (such as a general-purpose automatic spinning machine) synchronous feed accuracy. However, a rotary wheel is used for the light and powerful automatic spinning machine.
4. The main shaft has sufficient transmission torque and power. According to the specific process requirements, it can meet the constant torque or constant power adjustment. In addition, it is best to make the spindle speed and the longitudinal feed speed of the rotary wheel steplessly adjustable. On the one hand, it can meet the arbitrary selection requirements of the spinning process; on the other hand, it can maintain the surface rotation speed of the core mold during the spinning process. Possibility of constant feed per revolution.
