Abstract
The utility model relates to a high frequency switching power supply that can on - -spot dilatation, attend rectifier modular unit and the control unit that the lower floor arranged including AC distribution unit, DC distribution unit, a plurality of, rectifier modular unit internally mounted 1~5 rectifier modules, the control unit set up in rectifier modular unit, the capacity of rectifier module be 50A, its rectifier modular unit can according to on -the -spot demand by 1 (the total capacity is 200A), very simply expand to 3 (the total capacity is 700A). The utility model discloses when having kept original switching power supply, as long as increase rectifier unit module on original switching power supply basis, accomplish the dilatation, the construction cost has significantly reduced.
Description
Technical field
The utility model relates to electricity field, relate in particular to a kind of can the high frequency switch power of on-the-spot dilatation.
Background technology
Current wireless communication fast development, steel tower company is when starting to build radio communication rack base station, generally be difficult to the capacity expecting number of users in this base station range in operator's future such as China Mobile, China Telecom, CHINAUNICOM, often radio communication rack base station has just been built up soon just needs dilatation, and high frequency switch power also will increase capacity thereupon.The original power supply if dismantled, changes more jumbo high frequency switch power, not only consumes the time, also can cause very large waste.
Summary of the invention
The purpose of this utility model be to provide a kind of effectively can solve above-mentioned technological deficiency can the high frequency switch power of on-the-spot dilatation.
A kind of can the high frequency switch power of on-the-spot dilatation, comprise Alternating Current Unit, Direct Current Distribution Unit, several levels arrangement rectifier module unit and monitoring unit, 1 ~ 5 rectifier module is installed in described rectifier module unit inside, and described monitoring unit is arranged in rectifier module unit; The capacity of described rectifier module is 50A.
Described rectifier module unit has three layers, is connected and fixed by front column and rear column, and described the superiors' rectifier module unit inside is provided with four rectifier modules and a monitoring unit; Described front column 6 is " L " shape with the cross section of rear column 7.
The female copper bar of positive and negative electrode of described rectifier module unit is connected with the female copper bar of the positive and negative electrode of Switching Power Supply with two dilatation copper bars respectively.
Described Alternating Current Unit is drawn in AC power cord rectifier module unit extremely, receives the alternating current input of rectification module respectively.
The utility model, while remaining original Switching Power Supply, as long as increase rectifier unit module on original power supply basis, completes dilatation, greatly reduces construction cost.

Embodiment
Below in conjunction with accompanying drawing, the utility model is described in further detail:
A kind of can the high frequency switch power of on-the-spot dilatation, comprise Alternating Current Unit 1, Direct Current Distribution Unit 2, rectifier module unit 3 and monitoring unit 4 form, described rectifier module unit 3, as shown in Figure 2, rectifier module unit can install 5 modules, the capacity of rectifier is 50A, because monitoring module installed by 1 needs, therefore 4 rectifier modules can only be installed, rectifier module unit 3 quantity can be 1 to 3, if wherein 1, this power supply complete machine capacity is 200A, if scene is increased to 2, then capacity is corresponding is increased to 450A, maximumly can be increased to 3 in scene, then capacity is 700A.
Embodiment: the dilatation of 450A switch power supply system is to 700A switch power supply system
As Fig. 3, rectifier module unit rack 8 is arranged on below 450A Switching Power Supply, M3 screw is first utilized to be connected by the left side plate of the left and right sides upper plate of rectifier module unit rack 8 with the rectifier module unit rack of top, rectifier module unit rack 8 and 450A Switching Power Supply are fastenedly connected (to 450A, frame connected mode is identical in switch power supply system 200A dilatation) by the L-type front column 6 and the L-type rear column 7 that recycle 19 inches.
After frame being connected, as shown in Figure 4, with two dilatation copper bars 9, female for the positive and negative electrode of 450A Switching Power Supply copper bar is connected (to 450A, busbar connected mode is identical in switch power supply system 200A dilatation) with the female copper bar of the positive and negative electrode of rectifier module unit 3 respectively.
Then, draw AC power cord to the rectifier module unit 3 of dilatation from the Alternating Current Unit 1 of Switching Power Supply, receive the alternating current input of rectifier module 5 respectively.
Finally by from beginning to end for monitor data line, insert rectifier module 5, energising, confirms the operating state of each rectifier module 5 by monitoring unit 4.
