Description

Technical Field

[0001] This utility model relates to power supply and distribution systems, and more specifically, to a novel public lighting power distribution system for ultra-high-rise residential buildings. Background Technology

[0002] According to Appendix A of the "Standard for Electrical Design of Civil Buildings" GB51348-2019, which classifies the main electrical loads of various types of buildings in civil buildings, corridor lighting and security lighting in Class I high-rise residential buildings with a building height greater than 54 meters are classified as Class I loads. Furthermore, according to the aforementioned standard, Class I loads should be supplied by two low-voltage circuits from a dual power source, switched at the terminal distribution box. The specific power supply and distribution structure is as follows... Figure 1 As shown.

[0003] In the current public lighting power distribution system, a public lighting power distribution system box is set up approximately every 5 floors to supply power to the public lighting, sockets, and air conditioning equipment on the nearest 5 floors. For example... Figure 2 As shown, a normal municipal power supply and a backup generator power supply are drawn from the low-voltage power distribution room as the two main power supply circuits for the public lighting power distribution system. T-junction boxes are installed on the main and backup main circuit cables in front of each floor's public lighting power distribution system box, and cables are led out to the two main and backup circuit breakers in the public lighting power distribution system box. Then, through a dual power transfer switch, power is supplied to the subsequent public lighting, sockets, and air conditioning equipment.

[0004] However, according to Appendix A of the "Standard for Electrical Design of Civil Buildings" GB51348-2019, only the power supply for corridor lighting and duty lighting needs to be guaranteed; the power supply for sockets and air conditioning equipment in the public lighting distribution system box does not need to be guaranteed. Currently, the main and backup circuit cables are configured for maximum load, which means that the cable cross-sectional parameters, circuit breaker parameters, and generator capacity of the main circuit must all be configured according to the maximum load. When the main and backup circuits are activated, the load is often only the lighting load; therefore, configuring the cables, circuit breakers, and generators of the main and backup circuits for maximum load results in wasted resources. Utility Model Content

[0005] The technical problem this invention aims to solve is to address the shortcomings of existing technologies by providing a novel public lighting distribution system for ultra-high-rise residential buildings, which eliminates the need for configuration based on the maximum load of each floor, thereby reducing the overall cost of the system.

[0006] This utility model discloses a novel public lighting power distribution system for ultra-high-rise residential buildings, comprising a cable, a T-junction box, and a circuit breaker in the main circuit, and a cable, a T-junction box, and a circuit breaker in the main and backup circuits. The circuit breaker's output terminal is connected to a socket / air conditioning load busbar, which is connected to an input terminal of a dual-power transfer switch via a power supply line. The circuit breaker's output terminal is connected to the other input terminal of the dual-power transfer switch, and the output terminal of the dual-power transfer switch is connected to a lighting busbar.

[0007] Preferably, the power supply line is equipped with a circuit breaker.

[0008] Preferably, a residual current detector is installed on the cable between the dual power supply switch and the lighting busbar.

[0009] Beneficial effects

[0010] The advantages of this utility model are: by dividing the electrical load in the public lighting distribution system box into two types of loads, namely lighting and socket / air conditioning equipment, the cross-sectional area of ​​the cable in the main and backup circuits and the rated power of the upstream circuit breaker are reduced. The main and backup circuits do not need to be configured according to the maximum load of the floor, thus avoiding the waste of maximum configuration resources and reducing the overall cost of the system.

Detailed Implementation

[0015] The present invention will be further described below with reference to embodiments, but this does not constitute any limitation on the present invention. Any limited modifications made by any person within the scope of the claims of the present invention are still within the scope of the claims of the present invention.

[0016] See Figure 3This utility model discloses a novel public lighting power distribution system for a high-rise residential building, comprising cable 1, T-junction box 2, and circuit breaker 3 in the main circuit, and cable 4, T-junction box 5, and circuit breaker 6 in the main and backup circuits. Cable 1 is connected to the municipal power supply, with the other end connected to T-junction box 2. T-junction box 2 branches into two paths: one connecting to T-junction boxes on other floors, and the other connecting to circuit breaker 3. Similarly, cable 4 is connected to a generator, with the other end connected to T-junction box 5. T-junction box 5 branches into two paths: one connecting to T-junction boxes on other floors, and the other connecting to circuit breaker 6. Furthermore, each connection point between cable 1 and the municipal power supply, and cable 4 and the generator, is equipped with an upstream circuit breaker (not shown in the figure), used to control the on / off state of the power supply circuit. The above wiring method is consistent with existing wiring methods and will not be discussed further.

[0017] The output terminal of circuit breaker 3 is connected to the socket / air conditioning load busbar 9, which is connected to one input terminal of the dual power supply transfer switch 7 via a power supply line 11. Circuit breaker 3 10 is installed in the power supply line 11. The output terminal of circuit breaker 6 is connected to the other input terminal of the dual power supply transfer switch 7, which is connected to the lighting busbar 12. In the main circuit, the circuit input first passes through the socket / air conditioning load busbar 9, which distributes power to each socket and air conditioning load, and also provides power for the lighting circuit. Since the overall load remains constant in this main circuit, the cross-section of cable 1 remains the same as the existing one, and the upstream circuit breaker between cable 1 and the municipal power supply also remains the same as the existing one, i.e., a circuit breaker with a rated current of 160A. In the main and backup circuits, if the main and backup circuits are activated, the circuit input is directly input to the lighting circuit after passing through the dual power transfer switch 7. This eliminates the need for the main and backup circuits, i.e., cable 4, to supply power to the socket / air conditioning load. Consequently, the cross-sectional area of ​​cable 4 can be smaller than that of the existing main and backup circuit cables. Furthermore, in terms of design, the upstream circuit breaker at the connection point between cable 4 and the generator can be changed from 160A to 63A. Due to the reduced end load, the rated loads of cable 4, circuit breaker 2, and generator in the main and backup circuits can all be reduced, eliminating the need for configuration based on the maximum floor load, thus avoiding wasted configuration resources and reducing the overall system cost.

[0018] In this embodiment, a residual current detector 8 is installed on the cable between the dual power supply switch 7 and the lighting busbar 12 to detect residual current.

[0019] The above description is only a preferred embodiment of the present utility model. It should be noted that for those skilled in the art, several modifications and improvements can be made without departing from the structure of the present utility model, and these will not affect the implementation effect of the present utility model or the practicality of the patent.
