Description
The utility model belongs to the power distribution technical field, is specially a kind of intensive variable capacitance and energy-saving transformer station.
At present, making in the society and use in the transformer station that is used for power distribution, comprise high-tension apparatus, establish depressor and low-voltage equipment three parts combine,, have following unsurmountable defective though this transformer station can realize the task of its power transformation: the one, volume is big, manufacturing cost is high; The 2nd, this transformer station is comparatively economical under the running at full capacity situation, will cause waste of electric energy when seasonal, the intermittent unit that loads is used.
The purpose of this utility model is to provide that a kind of volume is little, low cost of manufacture, can carry out the intensive variable capacitance and energy-saving transformer station of capacity transfer.
The purpose of this utility model is achieved in that it comprises capacitance-adjustable transformer, the capacity transfer switch, high voltage load switch, plug-in fuse, the backup type fuse, fuel tank is formed, it is characterized in that high voltage load switch, plug-in fuse, the backup type fuse, capacitance-adjustable transformer, the capacity transfer switch all places the fuel tank of an all-sealed structure, plug-in fuse wherein, high voltage load switch and capacity transfer switch are fixed on the fuel tank tank wall with securing member respectively, the backup type fuse is fixed on the fixed head on the iron core folder of capacitance-adjustable transformer, on the oil tank wall at capacity transfer switch place, be provided with the mark of six class, wherein the 1-3 shelves are 100% capacity, the 4-6 shelves are 50% following capacity, the contact of each class all connects with the terminal of corresponding coil, low-voltage coil is three sections coileds in the line, I, the II section is respectively 73% circle, the III section is 27% circle, when full capacity 100%, high-tension coil is the wiring of △ type, I in the low-voltage coil, be connected in series with III section 27% circle coil again behind the coils from parallel connection of coils of two section 73% circle of II, 50% during with capacity, high-tension coil is the wiring of Y type, low-voltage coil I, II, III section coil is connected in series.
The utility model since adopted with high voltage load switch, plug-in fuse, backup type fuse, capacity transfer establish depressor, the capacity transfer switch all places a fuel tank, compact conformation, volume are little, the characteristics of low cost of manufacture so have.Because adopted scheme by capacity transfer switch control capacitance-adjustable transformer output capacity, thus the output capacity of capacitance-adjustable transformer can be adjusted according to the size of load, thus realize energy-conservation task.
Below the utility model is further described given with reference to the accompanying drawings embodiment as follows.
Accompanying drawing 1 is capacity transfer switch fixed contact and the winding diagram of moving contact when high-tension coil 100% capacity, and the switch rotating shaft is with moving contact 6 rotations, and 1-5 is a fixed contact, and 6 is moving contact, adopts the wiring of △ type this moment; Accompanying drawing 2 is capacity transfer switch fixed contact and the winding diagram of moving contact when low-voltage coil 100% capacity, and 1-4 is a fixed contact, and 5 is moving contact, and moving contact 5 also rotates with the switch rotating shaft.What adopt is that two sections coils from parallel connection of coils of I, II (promptly 1,2 join, and 3,4 join) are connected with the III coil then.During 50% following capacity, the rotating shaft of rotation capacity transfer switch makes that high-pressure side moving contact 6 contacts with fixed contact 2,3,4 respectively in the rotating shaft, what at this moment adopt is the wiring of " Y " type, and the low-pressure side moving contact also rotates with rotating shaft, respectively with 1,3,2,4 join, i.e. I, II, the series connection of III section coil.According to the size of user's electric weight, control by power supply department; Accompanying drawing 3 has provided electrical schematic diagram of the present utility model; The first head of the high pressure of capacitance-adjustable transformer 11 is drawn respectively on the binding post that is connected on plug-in fuse 10, draw from the other end, be connected on the lower end of backup type fuse 9, draw from the upper end and to be connected on the high voltage load switch 8, lead-out wire is connected on respectively on A, B, the C three-phase high-voltage elbow molded cannula 7 from the binding post of high voltage load switch 8 opposite sides.(plug-in fuse, high voltage load switch are separately fixed on the tank wall, and the backup type fuse is fixed on the fixed head above the iron core folder).High voltage just can pass through the elbow molded cannula like this, is used for cut-offfing load through on-load switch, plays the certain protection effect through overcurrent fuse.The tap lead of high-tension coil and the lead-in wire of low-voltage coil are connected on the capacity transfer switch, and the capacity transfer switch is fixed on the tank wall.Capacity transfer switch upper end is provided with the mark of six class, and 1-8 is 100% capacity, and 4-6 is 50% following capacity, and the contact of each class all is connected with the terminal of corresponding coil, its circuit mesolow coil grading coiled, and I, II section are respectively 73% circle.When full capacity 100%, what high-tension coil adopted is the wiring of △ type, in the low-voltage coil coils from parallel connection of coils of I, two section 73% circle of II is connected with the coil of III section 27% circle again, during 50% following capacity, what high-tension coil adopted is the wiring of " Y " type, and low-voltage coil adopts I, II, the series connection of III section coil.
