High-dynamic DC voltage controller of photovoltaic inverter

Abstract

The invention provides a high-dynamic DC voltage controller of a photovoltaic inverter. The high-dynamic DC voltage controller comprises a box body, nine groups of mounting seats are fixedly connectedin the box body in a rectangular array shape through bolts, electric appliance element mounting seats are fixedly connected on the mounting seats, and electric appliance elements are fixedly connected on the electric appliance element mounting seats through bolts. When the supporting pipe is in contact with the ground, friction between the supporting pipe and the ground can be replaced by rotation between the adjusting seat and the supporting pipe, the frictional resistance during adjustment is reduced, and the bottom plate can be prevented from being abraded by the supporting pipe; comparedwith the existing device, the device can realize horizontal placement of the box body; and the adjusting structure is reasonable and practical, and the problems that time is wasted during dismounting,moving is not convenient enough, and rapid horizontal adjustment cannot be achieved when the controller is placed on the uneven ground due to the fact that the number of electrical components in thecontroller cabinet body is large, the space is narrow, and a plurality of fixing bolts need to be dismounted are solved.

Description

technical field [0001] The invention belongs to the technical field of power distribution cabinet controller structure, and more specifically relates to a high dynamic DC voltage controller of a photovoltaic inverter. Background technique [0002] Ordinary transformers generally can only transmit DC input to DC output in a relatively short period of time. This is due to the limited inductance and the fast saturation of the magnetic core. This practical limitation can be overcome by reversing the terminals of the transformer before saturation occurs. It is a high dynamic DC voltage controller, and the high dynamic DC voltage controller has higher requirements on the working environment during installation and use. [0003] For example, the application number: CN201210402267.4, the present invention provides an electric locomotive electrical screen cabinet, including a cabinet body, an auxiliary converter, a charger, an auxiliary controller and a low-voltage electrical applian...

Problems solved by technology

[0007] In order to solve the above-mentioned technical problems, the present invention provides a high dynamic DC voltage controller for photovoltaic inverters to solve the existing problem that the maintenance is not convenient enough. The electrical components in the above application are all fixed in the cabinet by bolts. When the components need to be repaired after being damaged, because there are many electrical components in the cabinet and the space is small and multiple fixing bolts need to be disassembled, it is time-consuming to disassemble; moreover, the above application is not convenient to move, and when the ground is not smooth enough The problem of not being able to achieve quick level adjustment when placing
