Description

Low-voltage dual power case

Technical field

The utility model relates to power supply box technical field, is more particularly a kind of low-voltage dual power case.

Background technology

Power supply box is mainly the equipment that power consumption equipment provides operating power, the power supply box existed on the market mostly at present is single supply case, in circuit for generating fault or when there is the specific questions such as power failure, single supply case can not solve the problem for power-off effectively, existing solution arranges multiple single supply case, multiple single supply case makes area occupied comparatively large, adds land used cost, and arranges multiple single supply case and also add cost and drop into.

Summary of the invention

For solving the problem, the utility model devise a kind of when there is fault or power failure time can switch the low-voltage dual power case of power supply, its technical scheme is: described low-voltage dual power case comprises power supply I, power supply II, isolating switch I, isolating switch II, dual-power transfer switch, current transformer, supply module, protection module, it is characterized in that described power supply I and power supply II are connected to the end of incoming cables of dual-power transfer switch respectively by isolating switch I and isolating switch II, the leading-out terminal of dual-power transfer switch is connected to the end of incoming cables of current transformer, the leading-out terminal of described current transformer is connected with supply module, described supply module is minimum arranges two, the leading-out terminal of described current transformer is also connected with protection module.

Current transformer described in the utility model, is characterized in that described current transformer arranges three, is separately positioned on from three wires of dual-power transfer switch leading-out terminal extraction.

Supply module described in the utility model, is characterized in that described supply module is in series with circuit breaker.

Protection module described in the utility model, is characterized in that described protection module is made up of the fuse of connecting and protector.

The beneficial effects of the utility model are that low-voltage dual power case is provided with duplicate supply, can carry out the switching of another power supply wherein during a power failure; The protection module arranged can be protected the circuit in whole casing, equipment is run safer; And be provided with multiple supply module, multiple power supply can be completed simultaneously, supply module is also provided with circuit breaker separately, each supply module can be controlled respectively and power.
