Embodiment 1

[0030] Additional aspects and advantages of embodiments of the present invention will be set forth, in part, from the following description, and in part will be apparent from the following description, or learned by practice of embodiments of the invention.

[0031] A power distribution combination system suitable for limited power supply capacity provided by an embodiment of the present invention includes: three first-level power distribution boxes, the incoming wire ends of the three first-level power distribution boxes are respectively electrically connected to the three-way power supply, and the three first-level power distribution boxes are respectively electrically connected. The outlet ends of each first-level distribution box are electrically connected to two second-level distribution boxes, respectively, and the outlet ends of the second-level distribution boxes are electrically connected to a plurality of electrical devices, wherein the first-level distribution box inc...

Embodiment 2

[0036] The working process of the present invention will be described in detail below with a specific embodiment. It should be noted that this embodiment is only described as a specific embodiment, and the specific implementation is not limited thereto.

[0037] combine figure 1 , the embodiment of the present invention provides a power distribution combination system suitable for limited power supply capacity, such as figure 1 As shown, the power distribution combination system uses three power supplies of the same capacity to distribute power to three rooms with the same load, wherein each room requires incoming power supplies of two power capacities. The three power sources are connected to the three first-level distribution boxes through the first cable 1 respectively, and each first-level distribution box is divided into two distribution circuits, and each distribution circuit is connected to the two distribution boxes through the second cable 5 respectively. The second...

Embodiment 3

[0039] combine figure 2 , an embodiment of the present invention provides a power distribution method suitable for a power distribution combined system with limited power supply capacity, the method comprising the following steps:

[0040] S1: Connect the power cables from the power distribution room to three first-level distribution boxes, each with two outgoing loops, and each outgoing loop is connected to the second-level power distribution box.

[0041] S2: The six secondary distribution boxes are evenly distributed to three room areas to control the load operation in the three room areas respectively.

[0042] S3: Combine the secondary distribution boxes of any two room areas in the three room areas in pairs to obtain three sets of distribution box groups, and the three groups of distribution box groups are respectively powered by three first-level distribution boxes. .

[0043] S4: Set up a two-in-one electrical interlock between the power distribution circuits of the...

Abstract

The invention discloses a power distribution combination system suitable for limited power supply capacity and a power distribution method. The system comprises: three first-level distribution boxes, which are respectively connected with three-way power sources, and outlet ends of the three first-level distribution boxes. They are respectively connected with two secondary distribution boxes, the outlet end of the secondary distribution box is connected with a plurality of electrical equipment, and the primary distribution box includes a first distribution circuit and a second distribution circuit, the first distribution circuit and An electrical interlocking device is arranged between the second power distribution loops, the ends of the first power distribution loop and the second power distribution loop are respectively connected to the secondary power distribution box, and the secondary power distribution box of any two room areas in the three room areas The power distribution boxes are distributed in pairs by three first-level distribution boxes. The system can realize full-load operation of any room load. When a room is fully loaded, the loads in other rooms can be selected to run, and all loads can be run at half-load at the same time. When all loads are running at half-load at the same time, the electrical system still has Selectivity and reliability of protection.

Description

technical field [0001] The invention belongs to the technical field of power distribution system design, and particularly relates to a power distribution combined system suitable for limited power supply capacity and a power distribution method thereof. Background technique [0002] At present, the current power distribution system architecture in my country is usually the terminal distribution box to distribute power to each electrical equipment, and the power supply of the terminal distribution box is drawn from the main power supply box. Industrial projects, etc. (considering the simultaneous full load operation of all devices) are not suitable for application scenarios where the load capacity is much larger than the power capacity. In the form of electricity, the upper-level power supply box will have overload protection tripping. At this time, the traditional power distribution system architecture can no longer meet the selectivity of protection, and there is the defect o...
