Compatible with socket and cable output center-mounted power distribution pdu on both sides of the busbar

Abstract

The invention discloses a socket and cable output-compatible centrally-arranged bus-through two-side power distribution high-reliability PDU (Power Distribution Unit), which comprises an end-part waterproof connector, a wire incoming mounting end plate, a wire incoming insulated end plate, a shell, a wire arrangement device, an insulated end plate, a mounting end plate, multiple socket modules, a panel, a circuit breaker protection cover, a clamping-type lossless wiring terminal, a bus support, a circuit breaker, a bus-N, a bus-L, a bus-PE, a branch-N, a branch-L and a branch-PE. The quick punching clamping-type connection is low in resistance, reliable, durable, stable and small in temperature rise, and fire risks are eliminated; the PDU can realize internal annular wiring, single-point fault is eliminated, and the power-off range due to multi-point fault is reduced; no broken connection points exist in the whole bus, and connection is firm and nodes are clean; over high temperature rise can be avoided, and fire risks do not exist; power distribution reliability is high; power does not need to be cut off when the SPD modules are exchanged, working of a power supply object is not influenced, and the hot-plug function of the SPD modules in the PDU power distributor circuit can be realized.

Description

technical field [0001] The invention belongs to the field of cabinet power sockets, in particular to a precision power distribution unit. Background technique [0002] PDU refers to the power distribution unit. It is the acronym for "Power Distribution Unit" in English. It is mainly used in cabinets and other places that require high power supply reliability. Output interface compatibility: national standard, European standard, British standard can be selected as needed Standard, American Standard and other world standard power socket modules, terminal blocks or wires with plugs and other output interfaces can be combined in any way to meet the different needs of customers in many countries; dual power input can be realized; product end input, product front Different input positions such as panel input and product rear input; optional terminal blocks, 16A national standard plugs, various industrial couplers and other input interfaces. SPD module can provide multiple circuit...

Problems solved by technology

[0003] However, the load current of the PDU in the prior art is small; the output port is single and cannot be compatible with the socket and the wire with a plug; The stress effect will cause the temperature rise to be too high and there is a risk of fire; the internal busbar and connection point conductors are exposed to pose a safety hazard; a single point fault disconnection will cause output power failure; there are many busbar breakpoints and connectors, and the reliability is low; a single product can be Fewer output ports are provided; the load current is limited; the overall size is large, occupying valuable effective space in the cabinet; the efficiency of manual production and assembly is low, and the quality consistency is difficult to guarantee

[0004] At the same time, in the prior art, the SPD module in the PDU circuit is fixedly installed in the casing and connected to the circuit. If the SPD module is damaged during work, the entire PDU circuit must be cut off, and the SPD module or the entire PDU must be replaced. circuit, seriously affecting the work of the power supply object
