Description

Technical Field

[0001] This utility model relates to the field of SVG technology for photovoltaic power plants, specifically to a pipe sealing structure for an SVG cooling system. Background Technology

[0002] SVG refers to a device that uses a free-commutation power semiconductor bridge converter to perform dynamic reactive power compensation. SVG cooling systems should be installed wherever low-voltage transformers and large electrical equipment are installed. In addition, SVG cooling system equipment is also indispensable in the construction of photovoltaic power plants.

[0003] During the maintenance or testing of the SVG cooling system, it is necessary to close the valves of the coolant pipeline in the cooling system. After closing the valves, the screws of the coolant PE pipe need to be removed. However, in actual operation, a large amount of coolant will still flow out of the pipe during the maintenance process after removing the screws of the coolant PE pipe, which can easily cause coolant loss and waste, reduce the utilization efficiency of coolant, and at the same time, the outflowing coolant will also cause some pollution, which is not environmentally friendly. Therefore, this utility model proposes a pipeline sealing structure for the SVG cooling system. Utility Model Content

[0004] The purpose of this invention is to provide a pipe sealing structure for an SVG cooling system to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: an SVG cooling system pipe sealing structure, including a plug body, the plug body further including a rear plug, the rear plug adopting a cylindrical structure design, a threaded portion provided on the annular outer wall at the front end of the rear plug, a front plug fixedly installed on the front outer wall of the rear plug, a rear stepped plate fixedly installed on the rear end outer wall of the rear plug, and a knob fixedly installed on the front outer wall of the rear stepped plate.

[0006] Preferably, the front plug adopts a tapered structure design.

[0007] Preferably, the rear plug, front plug, rear step plate, and knob are all made of insulating rubber material.

[0008] Preferably, the rear plug, front plug, rear step plate, and knob are designed as an integral molded structure.

[0009] Preferably, the rear step plate is a disc-shaped rubber plate, and the thickness of the rear step plate is 5mm.

[0010] Compared with the prior art, the beneficial effects of this utility model are:

[0011] This utility model, through the use of a plug structure, can complete the coolant sealing work on the coolant PE pipe, effectively preventing coolant leakage and waste, improving coolant utilization efficiency, and effectively preventing coolant leakage and pollution, thus improving environmental protection.

[0012] The threaded connection provides a good seal, preventing coolant leakage from gaps. It also facilitates sealing and disassembly, and its structure is easy to use, with quick installation and disassembly features, effectively improving maintenance efficiency.

[0013] The threaded connection method can also improve the connection strength with the coolant PE pipe. Compared with the direct insertion method, the threaded connection can effectively avoid the phenomenon of the plug spraying out due to excessive internal pressure in the pipeline, effectively improve the sealing connection effect of the plug, with high connection strength and strong internal pressure resistance. Moreover, the plug structure of this utility model has a simple overall structure, low manufacturing cost, and good performance, making it suitable for widespread use. Attached Figure Description
