Embodiment 1

[0025] Additional aspects and advantages of embodiments of the invention will be set forth in the description which follows, and in part will be obvious from the description, or may be learned by practice of embodiments of the invention.

[0026] A group power distribution system suitable for limited power supply capacity provided by an embodiment of the present invention includes:

[0027] The first-level distribution box is electrically connected to the power supply. The first-level distribution box includes three power distribution circuits, and the three power distribution circuits are respectively connected to multiple secondary distribution boxes. The electrical equipment in each room area is electrically connected, among which multiple secondary distribution boxes are grouped into three groups of distribution boxes with large power capacity, the secondary distribution box is a dual power supply distribution box, and two of the dual power supply distribution boxes The po...

Embodiment 2

[0032] An embodiment of the present invention provides a power distribution method suitable for a group power distribution system with limited power supply capacity, including:

[0033] Lead the power cables from the power distribution room to the first-level distribution box. The first-level distribution box is equipped with three power distribution circuits. Each power distribution circuit is connected to multiple secondary distribution boxes. Multiple secondary power distribution boxes The boxes respectively control the operation of electrical equipment in multiple room areas.

[0034] Group the secondary distribution boxes in multiple room areas according to the power supply capacity to obtain three groups of distribution box groups with large and small power supply capacities, and the two power supplies of the secondary distribution boxes are located in different groups, and the three groups of distribution box groups The power is distributed by the three power distributi...

Embodiment 3

[0038] combine figure 1 and figure 2 , the embodiment of the present invention provides a room area group power distribution system with the same equipment capacity, the group power distribution system is suitable for power supply with limited power supply capacity, and at the same time supplying power to several electrical loads or room area electrical equipment not greater than 1.5 times the power supply capacity electrical systems such as figure 1 and figure 2 As shown, the power supply of the power distribution system is drawn from a certain power transformation and distribution room, and the power supply is electrically connected to the first-level distribution box through the first cable 1, and the first circuit breaker 2 is arranged on the first cable 1. When the circuit fails, the current of the first cable 1 is automatically cut off. The primary distribution box is divided into three distribution circuits, which are electrically connected to the main buses of the ...

Abstract

The invention discloses a grouping power distribution system suitable for limited power supply capacity and a power distribution method thereof. The system comprises a first-stage power distribution box which is electrically connected with a power supply, and the first-stage power distribution box comprises three power distribution loops which are respectively connected with a plurality of second-stage dual-power-supply power distribution boxes; the plurality of second-stage distribution boxes are respectively and electrically connected with electrical equipment in a plurality of room areas, the plurality of second-stage distribution boxes are divided into three groups of distribution boxes with different power supply capacities, two power supplies of each distribution box are located in different groups, and the three groups of distribution boxes are respectively supplied with power by three distribution loops of the first-stage power distribution box. A three-in-one electrical interlocking device is arranged among the three power distribution loops of the first-stage power distribution box, and an interconnection circuit breaker is arranged between any two power distribution loops in the three power distribution loops. Under the condition that the power capacity is limited, the use requirements of electrical equipment in each room in a normal steady state and an extreme operation scene are met, and the system is flexible and has protection selectivity.

Description

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