Description

Technical Field

[0001] This invention relates to the field of power distribution, and more particularly to an integrated power distribution device. Background Technology

[0002] Power distribution equipment, especially UPS power distribution equipment, typically has several power distribution circuits. For power distribution safety, a current sensor is installed on each power distribution circuit. Referring to CN200910075274, a UPS integrated power distribution system is disclosed, including several mains input / output interfaces, UPS input / output ports, surge protection modules, switching modules, data monitoring modules, current sensors, power supply modules, etc. In particular, if the several current sensors are arranged too closely, they are prone to mutual interference during detection; if they are arranged too far apart, it wastes space and the wiring is complex. Therefore, the power distribution system in CN200910075274 is very large, costly, and difficult to meet current miniaturization requirements.

[0003] Therefore, there is an urgent need for an integrated power distribution installation framework that can solve the above problems. Summary of the Invention

[0004] The purpose of this invention is to provide an integrated power distribution device mounting frame that can be used in power distribution devices with multiple power distribution circuits, especially in power distribution devices where multiple current sensors are set to detect the current of each power distribution circuit. The current sensors can be installed at an angle with different heights in the same longitudinal area, saving space, making the arrangement compact, and avoiding mutual interference between multiple power distribution circuits.

[0005] To achieve the above objectives, the present invention discloses an integrated power distribution device mounting frame, comprising a housing having a mounting cavity. A plurality of mounting plates are fixed within the mounting cavity along the left-right direction. Each mounting plate is arranged along the front-back direction of the mounting cavity. A mounting area for mounting current sensors is formed between adjacent mounting plates or between a mounting plate and a side plate of the housing. At least one mounting area has multiple mounting structures for mounting current sensors. These mounting structures are arranged along the front-back direction of the mounting cavity and have different heights. Each mounting structure can tilt the current sensor onto the mounting plate, causing the detection hole of the current sensor to tilt upwards, and the multiple current sensors within the mounting area have different heights.

[0006] Compared with existing technologies, this invention is used in power distribution devices with multiple distribution circuits, where multiple current sensors are used to detect the current in each circuit. Multiple mounting plates can be used to set up mounting areas for several current sensors laterally, and at least one mounting area can accommodate current sensors at different heights along the front-to-back direction, saving space and creating a compact arrangement. This results in a smaller final size power distribution device and avoids mutual interference between multiple distribution circuits. Furthermore, the current sensors are tilted upwards, which not only saves space to the maximum extent but also ensures that the cable only passes through the corresponding current sensor, forming an angle with the detection holes of adjacent current sensors, further preventing detection interference.

[0007] Preferably, the mounting structure has two or more mounting holes, and the plurality of mounting holes in each mounting structure are arranged along the front-back direction of the mounting cavity while being inclined relative to the horizontal direction.
