Detailed description of the invention
Referring to Fig. 1 ~ 4, a kind of single-phase high frequency Switching Power Supply that this utility model relates to, described single-phase high frequency Switching Power Supply includes the circuit board being installed in cabinet 1, described circuit board is provided with rectification circuit, High frequency filter anti-jamming circuit, switching power circuit and rectification filtering voltage stabilizing circuit, the outfan of described rectification circuit is connected with the input of High frequency filter anti-jamming circuit, the outfan of High frequency filter anti-jamming circuit is connected with the input of switching power circuit, and the outfan of switching power circuit is connected with the input of rectification filtering voltage stabilizing circuit.
When this utility model accesses electric energy meter, first via rectifier circuit rectifies, again through High frequency filter anti-jamming circuit, filter high frequency spurs, carry out AC-DC conversion by by switching power circuit, then be filtered voltage stabilizing, obtain galvanic current source, the work of supply of electrical energy table various piece;
Further, in described cabinet 1, parallel inserted has two pieces of busbars 2, busbar 2 one end is installed on circuit board, the other end is stretched and is put outside cabinet 1, and the transformator 3 of rectification circuit is installed between two pieces of busbars 2, the water channel 2.1 of U-shaped is had in described busbar 2, and two openings of the water channel 2.1 of U-shaped are positioned at busbar 2 and stretch on the one end being placed in outside cabinet 1, the opening of the water channel 2.1 of the U-shaped of two busbars 2 is connected, and (namely an opening of first busbar 2 is as water inlet end, one opening of another opening and second busbar 2 is connected, another opening of second busbar 2 is as water side), so that cooling water forms a circulation between two pieces of busbars 2,
Simultaneously, during installation, one plugboard 4 is set, this plugboard 4 has two spliced eyes 4.1 matched with busbar 2 size, and the size of the spacing between two spliced eyes 4.1 and transformator 3 matches, described plugboard 4 is secured by bolts on the lateral wall of cabinet 1, and on cabinet 1 through the through hole of busbar 2 more than spliced eye 4.1, thus reducing the requirement to cabinet 1 when processing installation, (hole size is much larger than busbar only to need first to be plugged in the through hole on cabinet 1 by busbar 2, therefore insert very convenient), then again plugboard 4 is inserted on busbar 2, spacing fixation is played by plugboard 4, finally plugboard 4 is bolted on the sidewall of cabinet 1, so for it is also an advantage that be in that, for producing the Switching Power Supply of Different Rule, have employed different size of transformator, owing to the through hole on cabinet 1 is more than the size of busbar, therefore only need to adopt with transformator relative to plugboard still can install on original cabinet, improve the versatility of assembling, reduce the manufacturing cost of power supply manufacturing enterprise.
