Description

Technical Field

[0001] The utility model relates to the technical field of modular buildings, in particular to a combined power supply box. Background Art

[0002] Modular construction is a construction method that prefabricates the building's components, also called modules, in a manufacturing plant and then assembles them on site. Each module typically consists of structure, walls, floors, ceilings, etc., and can contain pre-installed electrical, plumbing, and other systems.

[0003] Traditional modular buildings usually use 220V / 32A standard wall-mounted integrated boxes. However, in actual applications of modular buildings, the power of the electrical equipment used is equipped with 380V. If the 220V / 32A standard wall-mounted integrated box is used, it cannot meet the use requirements of 380V electrical equipment, resulting in certain usage limitations. Generally, in order to ensure the normal operation of the 380V electrical equipment, it is necessary to reinstall a 380V electrical box, which is easy to cause electrical safety hazards.

[0004] Therefore, a combined power box with flexible use is needed to solve the above problems. Utility Model Content

[0009] In order to meet the usage requirements of electrical equipment with different power, unlike the existing standard wall-mounted integrated box, a partition is fixedly installed in the box body for dividing the inner cavity of the box into a accommodating chamber A and a accommodating chamber B; by setting up the accommodating chamber A and the accommodating chamber B, 380V and 220V voltages can be integrated in the same box to ensure the normal operation of electrical equipment with different power.

[0010] In order to facilitate the installation of circuit breakers A and B and provide short-circuit protection for the circuit, miniature circuit breaker rails A for installing circuit breaker A and miniature circuit breaker rails B for installing circuit breaker B are fixedly installed in the accommodating chamber A and the accommodating chamber B respectively; an installation platform can be provided for circuit breakers A and circuit breakers B, and circuit breakers A and circuit breakers B can be used to reduce potential safety risks caused by current overload, short circuit and the like.

[0011] Preferably, in order to provide double protection for accommodating chamber A and accommodating chamber B, the accommodating chamber A and accommodating chamber B are respectively movably hinged with inner cover A and inner cover B for sealing on one side close to the outer cover; this can further isolate accommodating chamber A and accommodating chamber B from the external environment, protect the equipment from external factors, and make it easier for operators to perform separate inspection and maintenance of the equipment in accommodating chamber A and accommodating chamber B.

[0012] Preferably, in order to ensure the safety and stability of the equipment's electricity use, zero-row terminals for neutral wire connection are installed in both the accommodating chamber A and the accommodating chamber B; by setting up the zero-row terminals, the risk of incorrect connection during the neutral wire wiring process can be reduced, and the management and maintenance of the neutral wire is also facilitated.

[0013] Preferably, in order to ensure the safety and stability of the equipment's electricity use, grounding terminals for ground wire connection are installed in both the accommodating chamber A and the accommodating chamber B; this can ensure that the lines of the electrical equipment are effectively grounded, reduce safety risks, and facilitate the management and maintenance of the ground wire.

[0014] Preferably, in order to meet the different configuration requirements of modular building circuit breakers, multiple positions are provided on the miniature circuit breaker rail A and the miniature circuit breaker rail B; the number of circuit breakers A and circuit breakers B on the miniature circuit breaker rail A and the miniature circuit breaker rail B can be increased or decreased according to the configuration requirements of modular building electrical equipment to meet different electricity usage requirements.

[0015] (III) Beneficial effects

[0016] The power box is provided with partitions inside the box to divide the inner cavity of the box into a containing chamber A and a containing chamber B. It can integrate 380V and 220V voltages in the same box, thereby meeting the use requirements of electrical equipment with different powers and ensuring the normal operation of electrical equipment with different powers in modular buildings. At the same time, miniature circuit breaker rails A and miniature circuit breaker rails B for installing different circuit breakers are correspondingly provided in the containing chamber A and the containing chamber B, which can facilitate the installation of different circuit breakers in corresponding circuits for use, provide short-circuit protection for different circuits, and reduce potential safety risks caused by current overload, short circuit, etc. BRIEF DESCRIPTION OF THE DRAWINGS
