Embodiment 1

[0025] 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.

[0026] A grouped 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 distribution circuits, and the three distribution circuits are respectively connected with multiple second-level distribution boxes. The electrical equipment in each room area is electrically connected, wherein the multiple secondary distribution boxes are grouped into three groups of distribution boxes with the size of the power supply capacity, the secondary distribution boxes are dual power distribution boxes, and two of the dual power distr...

Embodiment 2

[0032] The embodiment of the present invention provides a power distribution method suitable for a grouped 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 provided with three distribution circuits, each of which is connected to multiple second-level distribution boxes and multiple second-level distribution boxes. The boxes separately control the operation of electrical equipment in multiple room areas.

[0034] The secondary distribution boxes in multiple room areas are grouped according to the size of the power supply to obtain three groups of distribution box groups with the size of the power supply capacity, and the two power supplies of the secondary distribution box are located in different groups, and the three groups of distribution boxes are grouped. The power distribution is carried out by the three distribut...

Embodiment 3

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

Abstract

The invention discloses a grouped power distribution system suitable for limited power supply capacity and a power distribution method thereof. The system comprises: a first-level distribution box electrically connected with the power supply; the first-level distribution box includes three power distribution circuits, which are respectively There are multiple secondary dual power distribution boxes connected, and the multiple secondary distribution boxes are electrically connected to the electrical equipment in multiple room areas, and the multiple secondary distribution boxes are grouped into three groups of power distribution with the size of the power supply capacity. The two power sources of each distribution box are located in different groups, and the three groups of distribution boxes are powered by the three distribution circuits of the first-level distribution box, and three distribution circuits of the first-level distribution box are provided with three All-in-one electrical interlocking device, and a tie breaker is set between any two of the three distribution circuits. The present invention satisfies the use requirements of the electrical equipment in each room under normal steady state and extreme operation scenarios under the condition of limited power supply capacity, 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 particularly relates to a grouped power distribution 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 supply capacity. Since the power of the loaded device is much larger than the power supply capacity, when all devices are running at full load at the same time, if the traditional configuration is used. In the form of electricity, the upper-level power su...
