But existing rectification filtering power volume is bigger, can not satisfy vehicle-mounted requirement.
The utility model content
The utility model technical issues that need to address just are to provide a kind of novel rectifying filter power supply, its efficient height, and volume is little, and contour structures can satisfy vehicle-mounted requirement.
For addressing the above problem, the utility model adopts following technical scheme:
A kind of novel rectifying filter power supply of the utility model, comprise the power supply main casing and be packaged in the interior power supply internal power device of power supply main casing, described power supply internal power device comprises power supply circuit board, described power supply main casing is a cylindrical housings, and described power supply internal power device is directly installed on the inwall of cylindrical housings after insulation is handled; Circular cylindrical shell intracoelomic cavity central authorities form an air channel, and a side of housing is equipped with blower fan, and opposite side is equipped with power supply terminal, and described power supply terminal and main circuit board are electrically connected.
Described power supply main casing front and back ends is respectively arranged with protecgulum and bonnet, and the front and back ends in the housing is respectively arranged with the sand net.
Described main casing is provided with supply socket.
Described main casing is installed on the vibration absorber.
Described vibration absorber is installed on the base plate.
Described base plate is provided with earth connection.
After all passing through insulation processing, all power supply internal power devices of the utility model are directly installed on the inwall of cylindrical housings; Central authorities in the cylindrical housings form the air channel, and a side of housing is equipped with blower fan, and opposite side is provided with power supply input and output binding post, and the protecgulum and the bonnet in housing and parlor are metal material.The utility model adopts the all-metal shielding, the internal entity encapsulation, and all-sealed integral structure, shock resistance, anti-vibration, moisture proof, anticorrosion, mould proof, anti-salt fog, Nai Gaore, anti-high and cold, tolerance is very strong under adverse circumstances very.
The utility model is for charge in batteries, for generator provides the novel rectifying filter power supply of DC control supply, can be applicable to the start-up control system of heavy-duty motor, circuit; High power DC electric power system in railway, mine, the Industry Control production line; Also can be used for power supply unit that wears out, detects various DC converter etc.Compare with traditional rectification filtering power and to have the following advantages:
1) efficient height, volume is little, and power density is big.
2) contour structures can satisfy vehicle-mounted requirement.
3) has good Electro Magnetic Compatibility.
4) anti-overload ability is strong.
5) ripple voltage is little.
