Embodiment 1

[0027] 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.

[0028] An embodiment of the present invention provides a power distribution interlocking system suitable for limited power supply capacity, including:

[0029] A primary distribution box electrically connected to the power supply, multiple secondary distribution boxes electrically connected to the primary distribution box, the outgoing terminals of multiple secondary distribution boxes are electrically connected to electrical equipment, and secondary The distribution box includes multiple power distribution circuits, and the multiple power distribution circuits are equipped with contactors. The contactors of multiple power distribution circuits are electrically interconnected in pairs to form an electrical interlock power distribution circuit...

Embodiment 2

[0035]An embodiment of the present invention provides a power distribution method suitable for a power distribution interlocking system with limited power supply capacity, including:

[0036] Lead the power cables from the power distribution room to the first-level distribution box. The first-level distribution box is equipped with multiple outlet circuits, and the multiple outlet circuits are respectively connected to multiple second-level distribution boxes. Boxes are allocated to the same room area or to several different room areas.

[0037] Group the electrical equipment at the end of the distribution box in the same room area to obtain two electrical equipment groups with the same load capacity, and set up an electrical interlock device between the power distribution circuits of the two electrical equipment groups. Control any one of the two electrical equipment groups to run at full load, or control some electrical equipment in the two electrical equipment groups to run...

Embodiment 3

[0040] combine figure 1 , the embodiment of the present invention provides a power distribution interlocking system and power distribution method suitable for equipment capacity less than twice the power supply capacity, such as figure 1 As shown, the total power supply capacity of the power distribution interlocking system is 45KW. The power supply of the power distribution system is drawn from a certain substation power distribution room, and the power supply is electrically connected to the first-level distribution box through the first cable 1. The power supply can only meet the operation of some electrical equipment. In order to facilitate the operation and maintenance management, the first-level power distribution box is divided into two power distribution channels, that is, two separate second cables 4 are set in the first-level power distribution box for power distribution, and two sections The ends of the second cable 4 are respectively connected with two groups of el...

Abstract

The invention discloses a power distribution interlocking system suitable for limited power supply capacity and power distribution method thereof. The system comprises a primary distribution box electrically connected with a power supply and a plurality of secondary distribution boxes electrically connected with the primary distribution box, each secondary distribution box is electrically connected with electrical equipment, each secondary distribution box comprises a plurality of distribution loops. And loop outlet ends are provided with contactors to form electrical interlocking. The interlocking system is suitable for an electrical system which has limited power supply capacity and simultaneously supplies power to a plurality of electrical loads or electrical equipment in a room area, wherein the power supply capacity of the electrical system is not greater than two times of the power supply capacity. Contactors are arranged in outlet loops of the same distribution box or different distribution boxes to perform electrical interlocking of different distribution loops, so that full-load operation of electrical equipment in any load or room area can be realized under the condition of limited power capacity, and simultaneous light-load operation of all loads or room area can also be realized; and meanwhile, power distribution of different granularities can be performed according to actual electrical equipment, so that the safety and flexibility of the system are improved.

Description

technical field [0001] The invention belongs to the technical field of power distribution system design, and in particular relates to a power distribution interlocking 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 equipment at the same time), are not suitable for application scenarios where the load capacity is much greater than the power supply capacity. For example, several PDUs (power distribution units) of the same specification are installed in the cabinet of a data center laboratory in a university. , due to the fact that the current power supply cannot be increased, t...
