[0002] At present, the space in modular buildings is relatively limited, and usually an integrated power box is used to integrate high-voltage and low-voltage equipment into one box to save space and simplify wiring.

[0003] When traditional electrical boxes used for integrated configuration of strong and weak currents are used, the high currents and high voltages in the strong current system will generate strong electromagnetic fields, which will be transmitted through cables, wires, metal structures, etc. However, due to space limitations, when strong and weak currents are integrated in the same electrical box, their positions are relatively close. Therefore, the electromagnetic generated by the strong current system will directly interfere with and affect the weak current system, causing the weak current equipment to fail to operate normally.

[0004] Therefore, a strong and weak current integrated power supply box is needed to solve the above problems. Utility Model Content

[0009] In order to reduce the electromagnetic interference of strong electricity to weak current equipment, unlike the existing integrated power supply box, an anti-electromagnetic component is fixedly installed in the weak current cavity for suppressing the electromagnetic interference of the strong current cavity on the weak current cavity; through the anti-electromagnetic component, the electromagnetic interference from the strong current cavity can be reduced, the weak current equipment can be protected from interference, and its normal and stable operation can be ensured.

[0025] In addition, in order to make the weak current line and the strong current line independent of each other, the partition 11 is a hard PMMA board.

[0026] It should be noted that in order to prevent lightning weather from impacting the electrical components in the power supply box 1, a surge protector is provided in the power supply box 1. The surge protector can monitor and limit the overvoltage in the circuit, thereby suppressing the propagation and interference of overvoltage; therefore, when overvoltage appears in the circuit, the surge protector will respond quickly and guide the overvoltage to flow into the ground wire, dissipating the overvoltage and preventing the overvoltage from causing damage to the equipment.

[0027] In this embodiment, when strong current and weak current are integrated in the same power supply box 1 for use, an electromagnetic interference filter is arranged in the weak current cavity 13, which can selectively pass the required signal frequency band based on the electromagnetic principle and suppress other irrelevant interference signals, thereby achieving the purpose of reducing electromagnetic interference; at the same time, the outer door 2 is arranged to protect the inside of the power supply box 1 to prevent dust or other substances from entering the inside of the power supply box 1 and damaging the equipment.

[0029] In this embodiment, the miniature circuit breaker rail A121 and the miniature short-circuit breaker rail B131 can provide an installation platform for the miniature circuit breaker, thereby facilitating the maintenance, replacement and overhaul of the circuit breaker by operators.

[0030] Furthermore, a zero-row terminal 122 for connecting a neutral line is fixedly installed in the strong current cavity 12 , and independent grounding terminals 14 for connecting a ground line are fixedly installed in both the strong current cavity 12 and the weak current cavity 13 .

[0031] In this embodiment, by providing the zero-row terminal 122 and the independent grounding terminal 14, a grounding protection system for electrical equipment can be established to reduce the risk of leakage and contact current to human safety.

[0032] Furthermore, the strong current chamber 12 and the weak current chamber 13 are both movably hinged with inner doors 15 on one side close to the outer door 2 .

[0033] In this embodiment, inner doors 15 are provided at the strong current chamber 12 and the weak current chamber 13 respectively, so that the strong current chamber 12 and the weak current chamber 13 can form separate spaces, thereby facilitating operators to perform separate maintenance on the strong current chamber 12 and the weak current chamber 13 .

[0034] When in use, an electromagnetic interference filter is installed on the miniature short-circuit guide rail B131 in the weak-current cavity 13. When an integrated power supply box for strong and weak currents is used, the electromagnetic interference filter can selectively pass the required signal frequency band based on electromagnetic principles and suppress other irrelevant interference signals, thereby achieving the purpose of reducing electromagnetic interference and ensuring the normal operation of the equipment in the weak-current cavity 13.

[0035] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
