Abstract

The utility model relates to an adjustable reactor used for a power distribution system, comprising an iron core and coil curls. The iron core is superimposed by silicon steel sheets with the thickness of 0.35 mm, and the iron core is divided into air gaps by insulating spacers along vertical direction. Two coil curls are respectively arranged on iron core columns, and the coil curls are led out of a tank cover via connecting with a high-voltage bushing. The iron core and the coil curls are arranged in an oil tank holding with transformer oil. The adjustable reactor is characterized in that the tank cover of the oil tank is provided with two tap switches, and four taps are respectively and symmetrically taken out of two coil curls; the taps of two coil curls with the same number are respectively connected with the corresponding contact joints of a tap switch in turn; the rest taps of two coil curls are respectively connected with the corresponding contact joints of the other tap switch in turn.

Description

Adjustable reactor

The utility model relates to a kind of Regulatable reactor that is used for distribution system.

Before the utility model was made, the reactor that is used for electric power networks was made up of unshakable in one's determination and coil.Iron core is that the silicon steel sheet with 0.35 millimeters thick is formed by stacking, and core limb vertically is separated into air gap with insulation spacer, the whole square shape that constitutes sealing unshakable in one's determination.Two coils are installed in respectively on the core limb, and series connection is mutually drawn case lid with the bushing connection, and unshakable in one's determination and coil is put into the fuel tank that fills transformer oil.The capacity of this reactor is fixed, and can't change, and has limited range of application.China's utility model patent " Regulatable reactor " (application number 85203059) has proposed the adjustable reactor of a kind of capacity, this reactor has been installed drive screw in coil rack, rotating screw bolt can make iron core do axial motion, changes the size of air gap, thereby changes inductance value.But, the complex structure of this reactor, and adjustable range is little.

The purpose of this utility model is to propose a kind of Regulatable reactor that can change the coil turns-in-series.

The Regulatable reactor that the utility model proposes is made up of unshakable in one's determination and coil, iron core is that the silicon steel sheet with 0.35 millimeters thick is formed by stacking, core limb vertically is separated into air gap with insulation spacer, 2 coils are installed on the core limb respectively, draw case lid with the bushing connection, unshakable in one's determination and coil is put into the fuel tank that fills transformer oil, it is characterized in that on the case lid of fuel tank 2 shunting switchs being installed, 2 coils are taken out the tap more than 4 respectively symmetrically, and 2 the same number of taps of coil are linked in sequence respectively on 1 corresponding contact of shunting switch, and the tap of 2 coil remainders is linked in sequence respectively on other 1 corresponding contact of shunting switch.

The Regulatable reactor that the utility model proposes is simple in structure, and is easy to operate, rotates the turns-in-series that 2 shunting switchs just can change 2 coils, thereby changes the capacity of reactor.Because coil has the tap more than 4, and is connected on the corresponding contact of shunting switch, change the position of shunting switch pivoted arm, just can realize the multiple combination of coil turns-in-series, thereby this reactor adjustable extent is big, and reliable and stable.

Followingly with reference to accompanying drawing concrete enforcement of the present utility model is further described, shown in Figure 1 is the structure chart of this reactor, Fig. 2 and shown in Figure 3 be the electric hookup of reactor.This reactor is made up of (5) unshakable in one's determination and coil (7), unshakable in one's determination (5) are that the silicon steel sheet with 0.35 millimeters thick is formed by stacking, (5) post vertical direction unshakable in one's determination is separated into air gap (6) with insulation spacer, 2 coils (7) are installed in respectively on iron core (5) post, draw case lid (4) with bushing (3) connection, (5) unshakable in one's determination and coil (7) are put into the fuel tank (8) that fills transformer oil (9), it is characterized in that on the case lid (4) of fuel tank (8) 2 shunting switchs (1 and 2) (being labeled as K1 and K2 on electric diagram) being installed, its model is as follows: K1 is SW-23-35/120, K2 is SWx-17-35/120,2 coils (7) (being labeled as L1 L2 L3 and L1 ' L2 ' L3 ' on the electric diagram) are taken out the tap more than 4 respectively symmetrically, respectively take out 7 taps in the present embodiment, and with the same number of tap (4 of 2 coils (L1 L2 L3 and L1 ' L2 ' L3 '), 2,1,3 and 4 ', 2 ', 1 ', 3 ') be linked in sequence on the corresponding contact of 1 shunting switch (K1) tap (5 that 2 coils (L1 L2 L3 and L1 ' L2 ' L3 ') are remaining respectively, 6,7 and 5 ', 6 ', 7 ') be linked in sequence respectively on the corresponding contact of other 1 shunting switch (K2).

Rotate shunting switch (K1 and K2), when the pivoted arm of K1 and K2 is in position shown in Figure 2, the tap 4 of coil L1 is connected through the tap 3 of shunting switch K1 and coil L2, tap 3 is connected with the tap 5 of coil L3 again, tap 5 is connected through the tap 5 ' of shunting switch K2 and coil L3 ', tap L5 ' connects with the tap 3 ' of coil L2 ', and tap 3 ' is connected through the tap 4 ' of shunting switch K1 and coil L1 '.So just the part number of turn of coil L1 and L2 and the appropriate section of coil L1 ' and L2 ' have been together in series.When the pivoted arm of K1 and K2 was in position shown in Figure 3, then the appropriate section of the part number of turn of coil L1, L2, L3 and coil L1 ', L2 ', L3 ' had been together in series again.
