Abstract: A stacking power supply cabinet is provided. The stacking power supply cabinet includes a top assembly and at least one battery module. In a case that the number of the battery module is more than one and the multiple battery modules are stacked sequentially from top to bottom, an electric connection path for power supply and/or storage is established among the stacked multiple battery modules, and the electric connection path is conducted via a power transmission line in the top assembly, and then the battery modules are charged. Thus, in the installation process of the power supply cabinet, the electric connection path for the power supply and/or storage among the multiple stacked battery modules is uncharged before the top assembly is installed, thereby reducing the risk of electric shock to the human body and improving the safety during the installation process of the stacking power supply cabinet.

Abstract: The present application discloses an energy storage cabinet, including a battery management module and a battery assembly. The battery management module is located on the side wall of the battery assembly, and the battery management module is electrically connected to the battery assembly. In the energy storage cabinet according to the present application, because the battery management module is located on the side wall of the battery assembly, the mounting height of the battery management module is effectively reduced, which is convenient for workers to control the battery management module, further facilitates the operation of the energy storage cabinet, and improves the safety of workers operating the energy storage cabinet.

Abstract: A magnetic liquid level gauge for measuring a boiler drum water level comprises an external cylinder body having a first upper portion and a first lower portion, and an internal cylinder body having a second upper portion and a second lower portion, the first upper portion and the second upper portion are connected to the boiler drum through a steam side sampling pipe, the second lower portion is connected to a water portion of the boiler drum through the water side sampling pipe, the external cylinder body and the internal cylinder body define a steam heat tracing chamber therebetween. A float inside the internal cylinder body is connected to a magnetic component in a magnetic component cylinder body. A display indicator is connected to a magnetic transmitter and a boiler drum pressure transmitter. A waveguide tube is disposed outside the magnetic component cylinder body and connected to the magnetic transmitter.
