Abstract

A power supply distributor is provided which can make safely isolation between a power supply distributor sector (32) and a power management network functional sector (31) safely. Secondary side signal lines (33,33a,33b,33c) already isolated, or secondary side signal lines (33,33a,33b,33c) already isolated and secondary side power connection lines connect the two sectors. There is no primary side high voltage electric power connection between the two sectors. The power management network functional sector (31) only has to be exchanged when the power management network functional sector is broken, without exchanging the power supply distributor, thereby without interrupting the power supply of the power supply distributor.

Description

Power distributor

The invention relates to a novel power distributor. Background technique

The traditional power distributor has an input power cable at one end, and an input source to the output socket. It supplies the required 3⁄4 source connected to the output power socket device, such as a computer server. When the power is exceeded, the current exceeds the power supply. When the load current of the distributor can be loaded, the power circuit is cut off by a circuit breaker or a fuse device to avoid overloading the wire. When the overload causes the power circuit to trip, the power connected to the output power outlet device, such as the computer server, is interrupted and cannot be operated. The equipment is shut down due to power failure, and the loss is great. The power distributor with an ammeter is manually checked by hand to check whether the power distributor is approaching full load, which can reduce the power interruption caused by the overload of the power distributor, but can not completely avoid the overload jump caused by human error. Because there is no network communication function, when the number of power circuits is large, it is time-consuming to check the ammeter, and it is impossible to know in real time that the power distributor is approaching full load, or even overloaded with power jump, and it is impossible to know in real time, immediately strain, and reduce power failure time. The traditional 3⁄4 source splitter does not provide the network communication functions required for power management. It can only be manually managed and monitored to avoid overloading.

The conventional network type power distributor adds a network communication function required for power management to a conventional power distributor. It is a two-layer structure of a network processor and embedded operating system and software code, and the microcontroller controls 3⁄4. Source and its software code. The network processor and its associated circuits and software are used as the number of transmissions in the network. I. The microcontroller and its associated circuits and software serve as inputs and outputs, power detection, overload protection, relay control, and transmission of signals to various internal power modules as well as transmitter modules or relay modules. The conventional network type power distributor is a two-layer architecture. The first layer is that the network processor is connected to the network through a network protocol such as network protocol IVHB, TCPIP, HTTP, UDPIP, etc., and the second layer is Microcontroller, between the two layers is serial communication such as UART, RS232, RS485, I2C, SPl, ODBUS or CANBUS. The network processor processes the network information, and the microcontroller processes the power information. The two processors have their own different programs and memories, each processing different information, and serially communicating with each other.

For example, DigiPower Corporation (Taipei, Taiwan) US patent 'US6507273' is based on the use of a network processor and its associated circuits and software to send, receive, and convert network packet information into a microcontroller-available information. The relay module exchanges the microcontroller and the network processor in a serial communication manner. To achieve the function of each power outlet socket switch of the remote control power distributor. A vertical network remote power management socket, as mentioned in U.S. Patent No. 7,171, 461, to U.S. Patent No. 7,043,543, to the name of the entire disclosure of which is incorporated herein by reference. At one end of the unit is the power input, and the power is assigned to the output socket of each of the power modules. Each power module is serially connected to the microcontroller by the I2C bus, and the relay on the power module is controlled by the set address. The network processor and its associated circuitry interact with the operating system to process network data, state and control signals between the external network, the internal I2C bus, and other ports. U.S. Patent No. 7,171,461 is characterized by the use of a microcontroller to process power control and network processors and their associated circuits. The embedded network signals embedded in the operating system and the data are converted into information available to the microcontroller, connected in an I2C serial communication manner. The controller and the network processor are configured to remotely manage each of the power outlets of the power distribution device. The network remotely manages an electric power pick-up device as mentioned in US Pat. No. 7,043,543, which includes a long body and a plurality of independently controllable power outlets. A power input is connected to one end of the unit, and power is distributed to each of the power outlets. The invention utilizes a microcontroller to process a power control and a network interface controller (NIC) and a network processor to process network signals and convert the data into information available to the microcontroller, and to connect the micro-controls in an I2C serial communication manner. And the network processor, to achieve the function of remotely managing the I power distribution and mounting each of the power outlets. Other Severtech patents, such as the US patent US704354318, utilize microprocessors to handle power control and network interface controllers and network processors to process network signals and convert the data into information available to the microcontroller, connected by i2C serial communication. The microcontroller and the network processor are used to remotely manage the function of each power outlet of the power distributor.

In the traditional power distributor, only the passive communication parts have no network communication function required for power management, so the gap is relatively difficult to occur. However, the known network type power distributor has increased the network communication function required for power management, and the electronic components are increased. Therefore, it is easier to send faults, the probability of needing maintenance is greatly increased, and the 3⁄4 force circuit needs to be interrupted for replacement and repair. The device must be disassembled and connected to the output power socket device to cause power interruption to the output power outlet device such as computer server device. .
