Description

Technical Field

[0001] The invention belongs to the technical field of small power system tools, and in particular relates to a communication power load transfer box. Background Art

[0002] Communication power supply is the basis for the normal operation of communication network, and its stability and reliability are directly related to the stability and reliability of the entire communication system. In communication network, 48V DC power supply is a widely used standard voltage, providing power support for various communication equipment. However, in the routine maintenance and overhaul of communication power supply, how to ensure that the normal operation of communication load is not affected when replacing or overhauling the power supply is an urgent problem to be solved.

[0003] Traditional communication power supply maintenance methods often need to be carried out in a power outage state, resulting in interruption of the communication system and affecting the normal operation of communication services. Especially in some key communication nodes, such as power center computer rooms, communication interruption may bring serious economic losses and social impacts.

[0004] The existing communication power supply maintenance methods have many inconveniences, such as long offline discharge test time, high labor intensity, low efficiency, etc. In addition, offline discharge test may also bring safety hazards, such as large voltage difference between battery packs and difficulty in parallel recovery.

[0005] With the continuous development of communication technology, communication power supply is also developing and innovating. At present, communication power supply has gone through the development process from industrial frequency transformer power supply to switching power supply and then to intelligent power supply. Intelligent power supply has the advantages of intelligent monitoring, unattended operation, automatic battery management, energy saving and environmental protection, high reliability, etc., and is the development direction of communication power supply. However, in the actual application of intelligent power supply, there are still some challenges, such as how to perform maintenance and replacement without power outage.

[0006] Load transfer technology is a technology widely used in power systems to transfer loads from one power source to another without power outages. In the field of communication power supply, load transfer technology can be used to achieve uninterrupted power supply to loads during communication power supply maintenance and replacement. By connecting to normal AC 220V and DC 220V power supplies, and then processing them through the module, a stable DC 48V power supply is finally output, ensuring that the communication load operates normally and reliably during the maintenance process.

[0007] Therefore, in order to solve the above problems, it is particularly important to develop a device that can perform power supply maintenance and replacement without power outages. Summary of the invention

For example, it can be a fixed connection, a detachable connection, or an integral one; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium; it can be the internal connection of two elements or the interaction relationship between two elements. Unless otherwise clearly defined, ordinary technicians in this field can understand the specific meanings of the above terms in the present invention according to the specific circumstances.

[0103] like Figure 1-Figure 2 The present invention discloses a communication power supply load transfer box, which comprises a frame 1. The frame 1 is internally constructed by a rectifier module 2, a monitoring module 3, a shunt, wiring terminals and structural components, and a battery pack 5 is configured as a backup; the device of the present invention has the characteristics of simple structure, convenient power distribution expansion, low cost and easy transportation.

[0104] like Figure 1 As shown, two rectifier modules 2 are provided, and four first rectangular frames are preset, which are adjusted according to actual conditions on site.

[0105] Specifically, it comprises a frame 1, which is a rectangular frame 1 with a hollow interior. The frame 1 is selected to aggregate all modules into one, which is convenient for transportation and use.

[0106] A rectifier module 2, a monitoring module 3, a shunt, an AC input terminal and a DC output terminal 4 are arranged inside the frame 1; the AC input terminal is used to provide an interface for inputting AC power, the rectifier module 2 converts the AC power input into the device into DC power, the shunt divides the DC power into multiple strands to supply different loads, and the DC output terminal 4 is used to connect the load to provide the load with the power required for operation. The entire process from the AC power input to the DC power output is continuously monitored by the monitoring module 3, and the staff will be immediately reminded if there is a fault in the entire device.

[0107] There are ten DC output terminals 4 and ten corresponding DC output switches 119, which divide the current into multiple strands, so that the device of the present invention can supply power to multiple loads.

[0108] like Figure 6 As shown, the overall idea of ​​the device of the present invention is that the AC power enters the power load transfer box from the AC input terminal, passes through the rectifier module 2 and the shunt, and is output from the DC output terminal 4; the monitoring module 3 supervises the above overall process, and the battery pack 5 can also be used for power supply. In this figure, four rectifier modules 2 are set, and the actual adjustment is based on the actual situation on site.

[0109] A battery pack 5 is also provided inside the frame 1; when the rectifier module 2 fails to work, the battery pack 5 can be started urgently to supply power.

[0110] The output end of the battery pack 5 is connected to the output end of the shunt; the direct current of the battery pack 5 is input to the load through the shunt.

[0111] The frame 1 comprises a first side surface 11, a second side surface 12, a third side surface and a fourth side surface. The first side surface 11 and the second side surface 12 are arranged opposite to each other, and the third side surface and the fourth side surface are arranged opposite to each other. The frame 1 is assembled into one body by four side surfaces, and a bottom surface and a top surface are arranged at both ends of each side surface, so that the frame 1 is arranged into a closed

[0112] like Figure 5 As shown, the first side 11 is provided with a first fixing frame 111, a second fixing frame 112, a third fixing frame 113, a fourth fixing frame 114, a fifth fixing frame 115 and a fixing hole 116; the fixing frame and the fixing hole 116 are provided for modules, interfaces or buttons inside the frame 1 to extend out, so that the staff can control the modules inside the frame 1 from the outside of the frame 1 and connect them.

[0113] The first fixed frame 111, the second fixed frame 112, the fourth fixed frame 114 and the fifth fixed frame 115 are rectangular frames, and the third fixed frame 113 is an "L"-shaped frame body 1; corresponding rectangular frames are set according to the shape of the protruding parts as required, and the shape is not fixed and can also be changed.

[0114] in:

[0115] The first fixing frame 111, the second fixing frame 112 and the third fixing frame 113 are fixed with a monitoring module 3 extending from the frame body 1;

[0116] The fourth fixing frame 114 fixes the rectifier module 2 extending from the frame body 1;

[0117] The fifth fixing frame 115 fixes an AC input switch 117, a unidirectional AC lightning arrester 118 and a DC output switch 119 extending from the frame body 1;

[0118] The second side surface 12 is provided with a ventilation hole 121 , a prefabricated hole 122 and a limiting hole 123 .

[0119] The position of the limiting hole 123 corresponds to the position of the DC output terminal 4 in the frame 1;

[0120] The position of the prefabricated hole 122 corresponds to the position of the AC input terminal in the frame 1 .

[0121] The ventilation holes 121 and the vent holes 26 have similar functions, both of which are to ensure the heat dissipation problem inside the structure. The device will generate a certain amount of heat during operation. If the heat cannot be effectively dissipated, it is likely to cause the temperature inside the frame 1 to rise, thereby affecting its performance and life. It is necessary to ensure that there is enough heat dissipation space.

[0122] The prefabricated hole 122 is used for the wire connected to the AC input terminal to enter, and the limiting hole 123 is used for the DC output terminal 4 to extend, so as to realize the connection between the communication power load transfer box of the device of the present invention and the external power supply and load to realize load transfer.

[0123] The prefabricated hole 122 and the limiting hole 123 are both embedded with wear-resistant pads 124 to prevent the cable from being worn out due to being placed on the edge of the hole for a long time.

[0124] The outer side of the DC output terminal 4 is covered with a wear-resistant part 41, which can limit the cable connected to the DC output terminal 4 to a certain extent, thereby preventing the cable connected to the DC output terminal 4 from shifting during the pulling process and causing damage to the internal structure of the interface.

[0125] The wear-resistant part 41 is provided with a connection hole 42 for allowing a cable connected to the DC output terminal 4 to enter.

[0126] The position of the connection hole 42 corresponds to the position of the DC output terminal 4 . Only the portion of the DC output terminal 4 connected to the cable is exposed, and the remaining portion is covered and protected by the wear-resistant part 41 . The cable passes through the connection hole 42 and is connected to the DC output terminal 4 .

[0127] The wear-resistant part 41 is made of rubber material, which is famous for its excellent wear resistance. It can effectively resist physical wear such as friction and extrusion that the cable may encounter during use, thereby extending the service life of the cable and its interface.

[0128] Rectifier module 2 refers to TR48-1800 series high frequency switch rectifier module 2, which is an ACDC module with AC voltage input and adjustable DC voltage output. Rectifier module 2 adopts DSP (digital signal processor) digital control, resonant soft switching, and high power factor.

[0129] TR48-1800 series high frequency switch rectifier module 2 has the following advantages:

[0130] 1. High efficiency

[0131] Resonant soft switching technology reduces energy consumption, meets energy conservation and emission reduction requirements, and saves electricity bills for customers.

[0132] 2. High power density

[0133] It can save customers space and reduce system costs.

[0134] 3.DSP digital control

[0135] Intelligence, fewer components, higher environmental stability, higher reliability, and more convenient capacity expansion.

[0136] 4. Low input harmonics

[0137] Reduce pollution to the power grid and increase the adaptability of the power grid.

[0138] 5. Wide input voltage range, wide output voltage range

[0139] Suitable for most occasions with different input and output voltages.

[0140] 6. Wide operating temperature range

[0141] Wide operating temperature range meets most harsh working environments

[0142] 7. Hot plug

[0143] Suitable for easy use and reduced maintenance costs.

[0144] The communication power load transfer box of the device of the present invention is based on the TR48-1800 series high-frequency switch rectifier module 2, and can quickly and efficiently complete the rectification process on the basis of ensuring that the rectifier module 2 inherits the TR48-1800 series high-frequency switch rectifier module 2, thereby assisting the communication power load transfer box of the device of the present invention to realize its required functions.

[0145] like Figure 4 As shown, the specific structure is: the rectifier module 2 includes a second shell 21, and the rectifier module 2 is integrated into one by the second shell 21, which is convenient for maintenance and can also be transported or replaced separately.

[0146] The second shell 21 extends out of the frame body 1 through the fourth fixing frame 114 , and the rectifier module 2 extends out of the fourth fixing frame 114 as a whole, so that it is convenient to take out and replace it as a whole.

[0147] The second housing 21 extends out of the frame 1 and is provided with an AC power indicator light 22, a current limiting indicator light 23, a fault indicator light 33, a module handle 25, a vent hole 26 and a module lock 27;

[0153] Red light on: input overvoltage, input undervoltage, over-temperature protection, over-current protection, output overvoltage, internal bus overvoltage, internal bus undervoltage;

[0154] Flashing red: Fan failure.

[0155] The module handle 25 is vertically fixed to the side of the second shell 21. When the second shell 21 is taken out from the frame 1, the module handle 25 is pulled to pull out the rectifier module 2 as a whole for replacement or repair. In addition, a buckle can be provided inside the frame 1 so that the module handle 25 is buckled and fixed inside the frame 1 to further fix the frame 1.

[0156] The second shell 21 extends out of one side of the frame 1 and is provided with a vent hole 26 to ensure the heat dissipation problem inside the rectifier module 2. Because the rectifier module 2 will generate a certain amount of heat during operation, if the heat cannot be effectively dissipated, it is likely to cause the module temperature to rise, thereby affecting its performance and life. It is necessary to ensure that there is enough heat dissipation space.

[0157] At the same time, the ventilation holes 26 provided on the side of the second shell 21 also reduce the overall weight of the rectifier module 2. In addition, to ensure the heat dissipation performance of the rectifier module 2, the number of ventilation holes 26 is determined according to the heat dissipated by the rectifier module 2 and can be flexibly adjusted.

[0158] The module lock 27 is fixed at the bottom end of the side of the second shell 21. After the rectifier module 2 enters the frame 1 as a whole, its position is adjusted to ensure that the rectifier module 2 is correctly positioned in the frame 1, and then the module lock 27 is pulled to fix the rectifier module 2.

[0159] The module lock 27 can be specifically referred to the existing locking structures on the market, such as a tongue-type lock, a slide-type lock, a spring-type lock, a rotary lock or a magnetic lock, to ensure that the rectifier module 2 is fixed in the frame 1.

[0160] The installation steps of rectifier module 2 are as follows:

[0161] Align the rectifier module 2 with the fixed frame, push the rectifier module 2 inward, and slide the lock to the right to lock the module. When the buckle is set inside the frame 1, the module handle 25 needs to be pressed inward to connect the module handle 25 with the buckle inside the frame 1.

[0162] The disassembly steps of rectifier module 2 are as follows:

[0163] First, unlock the module lock 27, then pull out the module handle 25, and then pull the module handle 25 to pull out the module.

[0164] The other side of the second housing 21 is provided with signal port pins 28 , module output pins 29 and module input pins 30 .

[0165] like Figure 3 as well as Figure 7 As shown, the signal port pins 28 include pin 1 211, pin 212, pin 3 213, pin 4 214, pin 5 215 and pin 6 216;

[0166] The signal of pin 211 is defined as CAN+.

[0167] The signal of pin 212 is defined as VCC+.

[0168] Pin 3 213 is the first reserved pin.

[0169] The signal of pin 214 is defined as CAN-,

[0170] The signal of pin 215 is defined as VCC-,

[0171] Pin 216 No. 6 is the second reserved pin;

[0173] The signal of pin 217 is defined as VOUT+.

[0177] The signal of pin 221 of No. 11 is defined as PE.

[0178] The signal of pin 222 of No. 12 is defined as single-phase power N or DC input negative.

[0179] The signal of pin 13 213 is defined as single-phase power L or DC input positive.
