The integrated inverter container 100 may preferably have the size of a conventional container to facilitate transportation.
It is understood that the direct current obtained by solar or wind power can be converted into an alternating current for industrial or domestic use by the inverter 111. The inverter 111 and the transformer 121 may be connected by a bus bar so that the transformer 121 can boost the alternating current output from the inverter 111. In addition, the transformer 121 can be connected with the ring main unit 131 through a bus to switch current through the ring main unit 131, and finally output in a grid-connected manner.
In the present invention, the integrated inverter container 100 includes at least one first accommodation chamber 110, at least one second accommodation chamber 120, and at least one third accommodation chamber 130, and the at least one first accommodation chamber 110, the at least one second accommodation chamber 120, and the at least one third accommodation chamber 130 are disposed along a length direction of the integrated inverter container 100. Specifically, in the present embodiment, fig. 1 exemplarily shows that the integrated inverter container 100 includes one first accommodation chamber 110, one second accommodation chamber 120, and one third accommodation chamber 130, and the second accommodation chamber 120 is disposed between the first accommodation chamber 110 and the third accommodation chamber 130. That is, the first accommodation chamber 110 may be located at a first end (i.e., a left end in fig. 1) of the integrated inverter container 100, and the third accommodation chamber 130 may be located at a second end (i.e., a right end in fig. 1) of the integrated inverter container 100.
As shown in fig. 3, the inner sides of the wall surfaces of the first accommodating chamber 110 and the third accommodating chamber 130 are provided with heat insulating layers to seal the first accommodating chamber 110 and the third accommodating chamber 130, respectively, so that the temperature, humidity, and dust-proof effect inside the first accommodating chamber 110 and the third accommodating chamber 130 can be ensured. Specifically, the first receiving chamber 110 is provided at the inner side thereof with an insulation layer 112, and the second receiving chamber 120 is provided at the inner side thereof with an insulation layer 132.
As shown in fig. 3, 5 and 6, the integrated inverter container 100 may further include a first end door 113 disposed at a first end and a second end door 133 disposed at a second end, the first end door 113 being configured as a part of the first receiving chamber 110, the second end door 133 being configured as a part of the third receiving chamber 130. Specifically, the first end door 113 is formed as a sidewall of the first receiving chamber 110, and the second end door 133 is formed as a sidewall of the third receiving chamber 130. The first end door 113 and the second end door 133 may be both of a double door structure to facilitate installation of the transformer 121 and the ring main unit 131 into the first accommodating chamber 110 and the third accommodating chamber 130, respectively. Further, the inner side of the first end door 113 may be provided with the insulation layer 112, and the inner side of the second end door 133 may be provided with the insulation layer 132.
The second accommodating chamber 120 has an opening to communicate the second accommodating chamber 120 with the outside atmosphere, thereby facilitating the hoisting of the transformer 121 and simultaneously being capable of satisfying the heat dissipation requirement of the transformer 121. Specifically, the opening may include a side opening 122 provided at a side of the second receiving chamber 120 and/or a top opening 123 provided at a top of the second receiving chamber 120. Specifically, in the present embodiment, a side opening 122 provided at a side of the second accommodation chamber 120 is illustrated in fig. 1. A top opening 123 provided at the top of the second receiving chamber 120 is shown in fig. 2. Alternatively, the side of the second receiving chamber 120 may not be provided with a side plate to form a side opening 122 completely opened at the side of the second receiving chamber 120. Also, the top of the second receiving chamber 120 may not be provided with a ceiling to form a top opening 123 that is completely opened at the top of the second receiving chamber 120. In one embodiment of the present invention, which is not shown, the side opening may be an opening provided on a side plate of the second receiving chamber, and the top opening may be an opening provided on a top plate of the second receiving chamber, so as to facilitate heat dissipation of the transformer 121.
Referring back to fig. 1, a side of the first receiving chamber 110 may be provided with a side door 114 for a person to enter and exit. The side door 114 may be a single door structure.

Since the weight of the transformer 121 is heavy, the height of the bottom side beam 124 of the second receiving chamber 120 is greater than the height of the bottom side beams of the first receiving chamber 110 and the third receiving chamber 130, so that the strength of the bottom side beam 124 of the second receiving chamber 120 is high to be able to carry a heavy load. Further, correspondingly, the height of the bottom cross member 125 of the second receiving room 120 may be greater than the height of the bottom cross member 117 of the first receiving room 110. Fig. 4 shows an exemplary bottom cross member 125 of the second receiving chamber 120 and the bottom cross member 117 of the first receiving chamber 110.
To facilitate installation of equipment having different installation height requirements, the top surface of the floor of at least two of the first, second, and third containment rooms 110, 120, and 130 is spaced apart from the bottom surface of the integrated inverter container 100 by a different distance. In other words, the distances from the bottom plate of at least two of the first accommodating chamber 110, the second accommodating chamber 120, and the third accommodating chamber 130 to the ground (support surface) may be different. Specifically, the spacing between the top surface of the bottom plate of the second accommodation chamber 120 and the bottom surface of the integrated inverter container 100 is greater than the spacing between the top surface of the bottom plate of the first accommodation chamber and the bottom surface of the integrated inverter container 100. That is, the transformer needs to be installed at a higher position with respect to the inverter.
As shown in fig. 3, the integrated inverter container 100 may further include auxiliary equipment (not shown), and an auxiliary transformer 116 is further disposed in the first accommodating chamber 110, the auxiliary transformer 116 being electrically connected to the inverter 111 to convert ac power output from the inverter 111 into 380V/220V and supply power to the auxiliary equipment. In particular, the auxiliary equipment may include electric equipment such as electric lamps, fans, etc. disposed inside the container. The auxiliary device is connected to an external power source (e.g., mains power accessed) so that the external power source can power the auxiliary device. The auxiliary transformer 116 may also be connected to auxiliary equipment so that the auxiliary transformer 116 can power the auxiliary equipment when the external power source is dead.
The integrated inverter container 100 may also include an unattended monitoring device (not shown). The unattended monitoring device may be electrically connected to an external (remote) workroom so that a worker may monitor the integrated inverter container 100 from within the workroom in real time. The unattended monitoring apparatus may include a smoke sensor, a camera, and the like, so that when an abnormality occurs in the interior of the integrated inverter container 100, such as a fire, the abnormality may be monitored in the work room and may be timely dealt with.
