All other embodiments, which can be made by those skilled in the art based on the embodiments of the utility model without making any inventive effort, are intended to be within the scope of the utility model.
In order to facilitate understanding of the technical scheme provided by the utility model, technical terms related to the utility model will be described first.
Ac distribution units refer to the distribution of ac power to different consumers or circuits to meet the power requirements of each device or circuit.
The circuit breaker is a protective electric appliance installed on a terminal distribution line and is mainly used for overload and short-circuit protection of the line and electric equipment.
The fuse is an electric appliance which fuses a melt by heat generated by the fuse when the current exceeds a specified value to break a circuit. The fuse is a current protector which is made up by using the principle that after the current exceeds a specified value for a period of time, the fuse body is melted by the heat generated by the fuse body so as to break the circuit.
Fuse-fuse refers generally to a fuse. The fuse is also known as a current fuse, which is defined by the IEC127 standard as a fuse link. It mainly plays the overload protection role. When the fuse is correctly arranged in the circuit, the fuse can be automatically fused to cut off the current when the current is abnormally increased to a certain height and heat, so that the safe operation of the circuit is protected.
In order to further understand the technical scheme provided by the utility model, the background technology related to the utility model will be described.
In the current daily electricity consumption, the socket is inconvenient to use in many occasions, and a wiring board is used for expanding the socket. The wiring board is one type of socket, and is a multi-hole socket formed by putting together a plurality of sockets. Simply stated, a patch panel receptacle refers to a multi-hole receptacle that has power cords and plugs and is movable. The wiring board socket can be multipurpose, saves space, saves circuits, and is simple and practical.
The patch panel cannot be turned on and off with a switch control, and in industrial power supply, industrial PDU (Power Distribution Unit ) is used. The PDU is a product designed for providing power distribution for cabinet-type installed electrical equipment, has various series specifications of different functions, installation modes and different plug-in position combinations, and can provide a proper rack-mounted power distribution solution for different power supply environments. In a power system, a common industrial PDU cannot meet the power supply requirement, and an ac distribution unit is used to supply power to equipment.
Most of the current power distribution units are 1-way input and 6-8-way output, and the input end is provided with a circuit breaker. Because each output is not provided with an independent breaker, the equipment is inconvenient to overhaul, and the whole power distribution unit is required to be powered off.
And when a certain power supply current is overloaded, the circuit breaker at the upper stage can be directly disconnected, and the normal operation of the whole system is affected.
In order to facilitate understanding of the technical solution provided by the present utility model, an electric power ac distribution unit provided by the present utility model will be described below with reference to the accompanying drawings.
