Description

Technical Field

[0001] The present invention relates to the technical field of transformer substations, in particular to a photovoltaic storage box type transformer substation. Background Art

[0002] The photovoltaic storage box substation is a box-type substation that combines photovoltaic power generation and energy storage systems. It is specially designed to provide power distribution and energy scheduling solutions for photovoltaic projects. Based on the traditional box-type substation, it integrates photovoltaic modules, energy storage equipment, transformers, switchgear and intelligent control systems.

[0003] However, traditional photovoltaic box-type substations are mostly installed outdoors and have a relatively simple structure. Photovoltaic components, energy storage equipment, transformers, switchgear and intelligent control systems are placed in a sealed box, and their heat dissipation and heat preservation effects are average. After long-term use in different seasons, the internal equipment may be damaged due to excessively high or low temperatures in the box, which in turn affects the normal use of the photovoltaic box-type substation. Secondly, when a short circuit occurs in some parts of the box and causes spontaneous combustion, if it is not handled in time, it will cause damage to other equipment and increase the overall maintenance cost of the photovoltaic box-type substation.

The airflow in the top cavity 102 can be introduced into the substation box 1 through the outer guide groove 601, the inner guide groove 602 and the guide frame 63. When fire extinguishing is required, the rotating longitudinal shaft 65 is controlled to rotate and drive the inner guide tube 62 to rotate in the outer guide tube 61, so that the inner guide tube 62 blocks the outer guide groove 601, and the agent guide clamp 64 and the inner guide groove 602 are communicated.

[0048] The bottom of the side wall of the outer frame 12 is fixedly installed with a protective oblique frame 10, which is located above the ventilation and dustproof part 4 at the bottom. By setting the protective oblique frame 10, the ventilation and dustproof part 4 at the bottom is protected from rain.

[0049] Fixing bolts 111 are provided at the four corners of the base 11 , and a door frame is mounted on the front frame 19 .

[0050] Working principle: When in use, multiple electrical devices are installed in the substation box 1. Under high temperature conditions in summer, the temperature inside the substation box 1 is too high and needs heat dissipation treatment. At this time, the first motor 35 is first turned on to drive the first worm 34 to drive the first worm wheel 33 to rotate, thereby controlling the rotation axis 31 to rotate, driving the sealing plate 3 to rotate in the side cavity 101, so that the end of the sealing plate 3 away from the rotation axis 31 contacts the corresponding seal 22, thereby sealing the top and bottom of the side cavity 101;

[0051] The outer guide groove 601 and the inner guide groove 602 are connected, and the inner guide tube 62 blocks the guide pipe 64;

[0052] Subsequently, the refrigeration module 9 is turned on, and the multiple first air guide fans 21 and the multiple second air guide fans 51 are turned on. The external airflow is dust-proofed through the ventilation dust-proof net 42 at the top position and introduced into the top cavity 102 through the ventilation inner groove 201 at the top position. After being cooled by the refrigeration module 9, it is introduced into the substation cabinet 1 through the guide outer groove 601, the guide inner groove 602 and the guide frame 63, and the hot air flow inside the substation cabinet 1 is simultaneously quickly discharged through the ventilation inner groove 201 at the bottom position and the ventilation dust-proof net 42, thereby effectively and quickly dissipating the heat of the internal environment of the substation cabinet 1, and preventing the equipment in the substation cabinet 1 from being damaged due to excessive temperature.

[0053] After the hot air flow inside the substation box 1 is completely discharged, the first motor 35 is turned on again to drive the first worm 34 to drive the first worm gear 33 to rotate in the opposite direction, thereby controlling the rotating horizontal axis 31 to rotate in the opposite direction, driving the sealing plate 3 to rotate in the side cavity 101, so that the sealing plate 3 is movably engaged with the inner end of the ventilation outer groove 301, and the sealing plate 3 closes the ventilation outer groove 301. At this time, the external closure of the substation box 1 is realized, and the side cavity 101 and the top cavity 102 are connected to each other. At this time, the cold air flow in the substation box 1 will be introduced into the side cavity 101 through the ventilation inner groove 201 at the bottom position, and circulated into the substation box 1 through the top cavity 102, realizing the internal circulation of the cold air flow in the substation box 1, and continuously performing heat dissipation treatment on the equipment in the substation box 1;

[0054] When it is winter, the sealing plate 3 is directly movably connected to the inner end of the ventilation outer groove 301, and the sealing plate 3 closes the ventilation outer groove 301. At this time, the outer closure of the substation box 1 is realized, and the side cavity 101 and the top cavity 102 are connected to each other, and the heating module 8 is turned on to quickly introduce the cold air in the substation box 1 into the side cavity 101 through the ventilation inner groove 201 at the bottom position, and circulate it into the substation box 1 through the top cavity 102, so as to realize the internal circulation of the air in the substation box 1. The air flow is heated by the heating module 8, and the internal environment of the substation box 1 is effectively heat-insulated by internal circulation, so as to prevent the temperature in the substation box 1 from being too low and causing damage to the equipment. At the same time, it prevents the external cold air flow from entering the substation box 1 through the ventilation dustproof part 4 and affecting the insulation effect;

[0055] Among them, when a short circuit occurs in the equipment in the substation box 1 and causes spontaneous combustion, the second motor 68 is immediately turned on to drive the corresponding second worm 661 to rotate, and the connection of the common drive shaft 67 is coordinated to drive multiple second worms 661 to rotate synchronously, thereby controlling the rotation of multiple second worm gears 66 and the rotating longitudinal shaft 65, driving the guide inner cylinder 62 to rotate in the guide outer cylinder 61, so that the guide inner cylinder 62 blocks the guide outer groove 601, and the guide agent clamping pipe 64 and the guide inner groove 602 are connected, and the fire extinguishing agent output system 73 is immediately turned on, and the fire extinguishing solvent is introduced into the corresponding guide agent clamping pipe 64 through the guide agent main pipe 71 and multiple guide agent branch pipes 72, and is directly introduced into the substation box 1 through the guide inner groove 602 and the guide frame 63, so that the equipment is promptly extinguished from the inner top of the substation box 1, preventing damage to other equipment in the substation box 1 and reducing the overall maintenance cost.

[0056] While embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions, and variations may be made to these embodiments without departing from the principles and spirit of the invention, and that the scope of the invention is defined by the appended claims and their equivalents.
