Abstract

A combined inverter is arranged, which includes at least two separate box bodies connected detachably, all components of the combined inverter are placed into the box bodies separately, and at least one electrical connection terminal is arranged outside each of the box bodies, and the electrical connection terminal of one of the box bodies is capable of being connected to the electrical connection terminal of another of the box bodies. Therefore, a structure connection and an electrical connection of the combined inverter is achieved, weight of the whole combined inverter is dismantled effectively on the premise of ensuring normal operation of the combined inverter, construction difficult of installation and transportation is reduced, and the combined inverter has high applicability even when having high power.

First claim

The invention claimed is:

1. A combined inverter, comprising: at least two separate box bodies connected detachably, wherein
all components of the combined inverter are placed into the box bodies separately,
at least one electrical connection terminal is arranged outside each of the box bodies, and the electrical connection terminal of one of the box bodies is capable of being connected to the electrical connection terminal of another of the box bodies; and
a connector, wherein the box bodies are connected detachably via the connector;
wherein a plurality of fixing holes are arranged onto a back surface of the connector facing toward a wall surface or a supporter, to fix the connector onto the wall surface or the supporter.

2. The combined inverter according to claim 1 , wherein the box bodies are arranged side by side, and a clamping plate extending in a side-by-side arrangement direction is provided for the connector, and a clamping groove is provided for each of the box bodies connected to the connector, the clamping groove of the box body is clamped with the clamping plate in the side-by-side arrangement direction.

3. The combined inverter according to claim 2 , wherein a first baffle and a second baffle are arranged respectively at two terminals of the clamping plate in the side-by-side arrangement direction, and the first baffle and the second baffle are used to limit relative sliding between the clamping groove and the clamping plate in the side-by-side arrangement direction at an installation position of the box body.

4. The combined inverter according to claim 3 , wherein a preset gap exists between the first baffle and/or the second baffle and the clamping plate, to enable a side wall of the clamping groove to slide to the installation position along the preset gap.

5. The combined inverter according to claim 3 , wherein a third baffle matched with the first baffle and the second baffle is provided for the clamping groove of the box body at the installation position; and
bolt holes are opened in the first baffle, the second baffle and the third baffle, to connect the first baffle to the third baffle and connect the second baffle to the third baffle via bolts.

6. The combined inverter according to claim 4 , wherein a third baffle matched with the first baffle and the second baffle is provided for the clamping groove of the box body at the installation position; and
bolt holes are opened in the first baffle, the second baffle and the third baffle, to connect the first baffle to the third baffle and connect the second baffle to the third baffle via bolts.

7. The combined inverter according to claim 1 , wherein the first clamping track and the second clamping track are arranged respectively onto back surfaces of the adjacent two of the box bodies facing toward the wall surface or the supporter, and one of the first clamping track and the second clamping track extends towards the other of the first clamping track and the second clamping track.

8. The combined inverter according to claim 1 , the first clamping track and the second clamping track are arranged respectively at connection faces of the box bodies where the box bodies contact with each other, to enable the first clamping track and the second clamping track to be located between the box bodies.

9. The combined inverter according to claim 1 , wherein the box bodies are arranged left and right, and the electrical connection terminal of each of the box bodies is arranged onto a bottom surface of each of the box bodies.
