Description

Integrated portable -48V communication emergency power supply

technical field

The invention belongs to the field of communication power supply systems.

Background technique

Most of the 110kV and 35kV substations of the State Grid Corporation use integrated power supplies to supply power to communication transmission equipment, and the communication power supply system is not equipped with independent battery packs. When the power is lost in the station or the integrated power supply is repaired, the integrated power supply cannot provide -48V power stably, which will cause the power failure of the communication equipment and affect the stable operation of the service channel. Therefore, the development of an integrated portable -48V communication emergency power supply, which can restore the power supply of the communication equipment in the station in time, has practical significance for solving the current problem.

SUMMARY OF THE INVENTION

The purpose of the present invention is to solve the above problems and provide an integrated portable -48V communication emergency power supply. When the power is lost in the station or the integrated power supply is repaired, it will not cause the power failure of the communication equipment and ensure the stable operation of the business channel. , to restore the power supply of the communication equipment in the station in time.

The technical solution of the present invention is achieved in this way, an integrated portable -48V communication emergency power supply, which is characterized by: including a miniature communication power supply converter, an integrated portable rack, a quick connection port for the communication power supply at the back, and a built-in lithium ion Battery pack, input power quick interface at the back, load terminals at the back.

The present invention has two independent power input functions, the input power can be 110V ~ 220V AC power or DC power; built-in lithium-ion battery pack (capacity 100Ah), to ensure uninterrupted switching to the built-in battery pack for power supply after the input power is cut off , so as to avoid the interruption of communication transmission caused by the loss of power of the communication equipment. Reasonable structure, advanced functions, integrated load output shunt and built-in battery pack function, and provide external wiring terminals, wiring does not need to disassemble the equipment, making installation and maintenance work safer and more convenient. Lightweight structure design, the total mass of this device does not exceed 17KG, equipped with portable handle and shock-absorbing rubber pad, easy to carry and easy to place.

Detailed ways

It can be seen from Figure 1 to Figure 6 that the integrated portable -48V communication emergency power supply includes a micro communication power converter 1, an integrated portable rack 2, a communication power quick connection port 3 at the rear, a built-in lithium-ion battery pack 4, and an input at the rear Power quick interface 5, load terminal 6 at the back.

The present invention: 1. It has the ability to connect to two different power sources, and can be arbitrarily connected to two AC power sources; two DC power sources; one AC power source and one DC power source. 2. The two power sources operate in isolation. When one power source fails, the other power source can still ensure the normal operation of the communication equipment. 3. It has a wide voltage working ability, and the input voltage range is 110V ~ 240V (AC or DC) can work normally. 4. The integrated communication power system is integrated with the power distribution unit, which maximizes the use of structural space and has 6 separate output branches (one of which is equipped with a quick interface, which can be connected to an extended battery pack through a quick interface device). 5. One set of lithium-ion battery pack is integrated inside. 6. When the external power supply is input, the device will charge the built-in lithium-ion battery pack (when an external battery pack is connected to the quick interface), and supply power to the transmission equipment at the same time. 7. After the input power is cut off, the built-in battery pack alone or in parallel with the external battery pack supplies power to the communication equipment.

The invention has reasonable structure and advanced functions, integrates the functions of load output shunt and built-in battery pack, and provides external connection terminals, which does not require dismantling equipment for connection, and is safer and more convenient for installation and maintenance. The equipped output shunt protection switch and rectifier module can be plugged and replaced without disassembling the equipment, without any wiring operation and other redundant work. The built-in battery pack can supply power to the communication equipment when the external power supply is completely interrupted, ensuring the stable and reliable operation of the communication equipment during maintenance operations. Lightweight structure design, the total mass does not exceed 17KG, equipped with portable handle and shock-absorbing rubber pad, easy to carry and easy to place.
