Overall structure is generally fairly simple, the Pressure-drop instability of many DC generators.
Summary of the invention
The purpose of the utility model is to provide a kind of a kind of three-phase multiplication of voltage circuit direct currents for being able to use and facilitating pressure drop stable
Generator.
The technical solution of the utility model are as follows: a kind of three-phase multiplication of voltage circuit DC generator, on the side of DC generator
It is provided with HT testing transformer, is provided with protective resistance between the HT testing transformer and DC generator, it is described
Protective resistance be configured along the side of DC generator and protective resistance and DC generator are connected with each other, sent out in direct current
Raw device is internally provided with filter condenser, and high-voltage rectification silicon stack, the high-voltage rectification silicon stack are provided with by filter capacitor
The side of filter condenser in DC generator, the company of being provided between the filter condenser and high-voltage rectification silicon stack
Connection device.
The protective resistance is AC charging protective resistance, and the AC charging protective resistance and high-potting become
Depressor is connected with each other.
The attachment device is clutch disk, is provided with connecting pin on clutch disk.
The utility model has the advantages that: the utility model uses three phase rectifier, and obtained direct current output waveform is more smooth,
So that the ripple factor of direct current is lower, while measuring and can find that the pressure drop of a component is relatively low, DC generator can fit
For exporting, electric current is big, ripple factor requires HVDC TEST power supply low, that pressure drop is small.
