Abstract
The invention discloses a three-phase input and three-phase output electro-desalting power supply, a primary side of which is a three-phase input and a secondary side of which is a three-phase output, wherein impedances of 100 percent are serially connected to loops of three phases of the primary side, different taps are arranged on a secondary high-voltage coil, different output high voltages are selected through a selection switch so as to adapt different kinds of crude oil; and in addition, the secondary side is also provided with one group of three-phase 100V measurement coils which are used for measuring actual output voltages of the three phases.
Description
Technical field
The invention belongs to crude oil electro-dewatering, refinery crude oil electric desalting equipment technical field, particularly a kind of a kind of three-phase input three-phase output electric desalting power supply for petroleum chemical industry Crude Oil electric desalting equipment.
Background technology
what crude oil electro-dewatering and refinery crude oil electric desalting all used at present is single phase transformer, mainly contains the AC electro-desalting transformer (patent No.: 97200623.0), alternating and direct current desalting transformer (the patent No.: 93246305.3), high-speed electric desalting transformer (the patent No.: 01201736.1), namely each transformer is only used two-phase electricity (A, B phase or other two-phase), other once being out of use mutually, along with the oil field and refinery more and more higher to the requirement of plant factor, it is three-phase transformer that urgent hope changes present electro-dewatering electric desalting single phase transformer, thereby solve the problem of three-phase imbalance and the capacity that reduces higher level's transformer, especially in the situation that oil property worse and worse, electro-dewatering electro-desalting transformer running current is also increasing, three-phase imbalance is also more and more serious, the load of upper level transformer is also increasing, the such transformer of three-phase input three-phase output can be good at addressing these problems, platform at sea particularly, because most offshore platforms electricity used is all sent out with generator, offshore platform used is higher to the requirement of three-phase equilibrium, do not allow to use powerful single-phase electric devices as the electrical dehydrator transformer, originally in order to satisfy large like this single-phase electric devices, have to select larger generating set, increased facility investment.
Summary of the invention
The objective of the invention is to be to provide a kind of three-phase input three-phase output electric desalting power supply, its primary side is the three-phase input, all alters in the loop of primary side three-phase and has connect 100% impedance.Secondary side is three-phase output, and different taps is arranged on the secondary high-pressure coil, selects different output high pressure by system selector switch K1, to adapt to different crude oils.Secondary side also has one group of three-phase 100V measuring coil in addition, measures respectively the voltage of the three-phase of actual output.
As above said a kind of three-phase input three-phase output electric desalting power supply, is characterized in that once being input as three-phase, and secondary is output as three-phase;
As above said a kind of three-phase input three-phase output electric desalting power supply is characterized in that all altering in three groups of coils of primary side of transformer and has connect 100% impedance;
As above said a kind of three-phase input three-phase output electric desalting power supply, is characterized in that different voltage taps is arranged on second siding ring, can select different output voltages by system selector switch K1;
As above said a kind of three-phase input three-phase output electric desalting power supply, is characterized in that secondary side has three groups of coils to measure respectively the running voltage of three-phase reality.

Embodiment
Below in conjunction with drawings and Examples, content of the present invention is further elaborated.
The alternating-current of the three-phase 380V (6000V) that at first will attract from switchgear building, receive respectively a of transformer, b is on the c terminal, from A, B on the C high-voltage connection terminal guides to high voltage electric in electrical desalter on battery lead plate, by adjusting the position of K1 system selector switch, select different output voltages, form ac high-voltage electric field (as shown in Figure 2) in electrical desalter, by observing the actual measured value of three 100V measuring coils, can calculate the effective electric-field intensity in electrical desalter.Because the load of three-phase is identical, the running current of three-phase is also just identical, thereby has reached the purpose of balance.
