This equipment has the advantages of high efficiency, reliability, safety, and energy saving, and is widely used in power supply systems.

[0003] Existing return flow control cabinets have the following disadvantages when in use: As energy storage develops towards a high energy-to-volume ratio and intelligence, the return flow cabinet needs to be highly integrated and have precise control and monitoring functions. Most return flow cabinets on the market currently only merge batteries, and their control and monitoring functions are missing or imperfect. To this end, we propose a highly integrated return flow cabinet with control and monitoring functions. Utility Model Content

[0004] The main purpose of the present invention is to provide a highly integrated junction box with control and monitoring functions, which can connect the outputs of each cluster of high-voltage boxes in parallel and control the disconnection and closing before outputting them to the PCS, and control and monitor each circuit, which can effectively solve the problems in the background technology.

[0005] In order to achieve the above purpose, the technical solution adopted by the utility model is:

[0006] A highly integrated junction box with control and monitoring functions includes a cabinet frame and a cabinet door. The cabinet door is movably connected to the surface of the cabinet frame. Main beams are vertically arranged inside the cabinet frame, and cross beams are horizontally overlapped between the main beams. Electrical installation plates are horizontally overlapped between the cross beams. A DC high-voltage main circuit, an AC power distribution and monitoring circuit, a battery compartment and a UPS are sequentially arranged inside the cabinet frame. A cooling fan is installed on the top of the cabinet frame.

[0007] Furthermore, the DC high-voltage main circuit includes a DC circuit breaker, a lightning arrester, a DC fuse and a lightning protection fuse. The DC circuit breaker and the DC fuse are electrically connected to the lightning arrester and the lightning protection fuse. The DC high-voltage main circuit is a DC circuit in which the positive and negative poles of each cluster of high-voltage boxes are respectively converged, passed through the DC fuse, and then output to the positive and negative poles of the PCS through the DC circuit breaker. The lightning arrester and the lightning protection fuse play a role in lightning protection.

[0008] Furthermore, an air inlet is provided at the bottom of the cabinet frame, and an air outlet is provided at the exhaust end of the cooling fan; when the cooling fan is in operation, air is sucked in through the air inlet to remove heat inside the cabinet and discharged from the air outlet.

[0009] Furthermore, a mounting hole is opened inside the beam and a beam rivet nut is set inside the mounting hole, and a rivet nut is set on the side of the electrical installation plate; the beam is connected to the cabinet frame and the electrical installation plate through the mounting hole and the beam rivet nut.

[0010] Furthermore, a monitoring screen, a status indicator light and a control button are installed on the surface of the cabinet door; the operating status of the electrical equipment can be monitored by the monitoring screen and the status indicator light, and the control button can regulate the electrical operation.

[0011] Compared with the prior art, the present invention has the following beneficial effects: the cabinet frame is formed by bending and welding sheet metal, the cabinet frame and the cabinet door are connected by hinges and door locks, the cabinet frame is connected to the other three side panels by fasteners, and the main beams of the cabinet frame are connected by welding. During production and assembly, the internal electrical components can be installed first and then the side doors can be installed, which saves the reserved installation space and makes the overall volume of the junction cabinet smaller. The DC high-voltage main circuit, AC power distribution and monitoring circuit, battery compartment, UPS and cooling fan are arranged in sequence from bottom to top inside the junction cabinet. The reasonable and regular layout makes the space utilization higher and thus reduces the overall size of the junction cabinet. A monitoring screen, status indicator lights and control buttons are provided on the surface of the cabinet door.

When the AC power supply is cut off, the battery supplies power to load two through the UPS to ensure that load two will never be out of power, so that internal communication and control will never stop. At the same time, the overall equipment has multi-layer safety control functions. Each circuit is equipped with a circuit breaker for on and off, and a lightning arrester is also provided to provide all-round safety protection for power safety. BRIEF DESCRIPTION OF THE DRAWINGS
