Embodiment
The utility model will be further described below in conjunction with accompanying drawing.
As shown in Figure 1, the utility model comprise current transformer 13, secondary control cabinet 15, auxiliary switch 19, insulating sleeve 10 and be arranged on current transformer 13 tops contact 12, be arranged on the vacuum interrupter 9 in the insulating sleeve 10 and be arranged on the cabinet 16 that insulating sleeve 10 belows are used to place operating mechanism; Be provided with Monostable permanent magnetic mechanism 14 in described cabinet 16, Monostable permanent magnetic mechanism 14, excess of stroke tube 18, insulating bar 17, vacuum interrupter 9 connect on same axis successively.In cabinet 16, also be provided with and comprise the control board 11 that selects phase control module and mechanism action control module.
As shown in Figure 2, concentrate problem easy to wear for solving insulating bar 17 and 19 drive disk assembly stress of auxiliary switch, end in the switch rotating shaft 20 of auxiliary switch 19 is provided with gear 21, and gear 21 is meshed with tooth bar 22, and an end of tooth bar 22 is connected with insulating bar 17.
As shown in Figure 3, described Monostable permanent magnetic mechanism 14 comprises the porose soft iron core 6 of casing 8 and center, the bottom is provided with the moving iron core 5 of disc in casing 8, center at moving iron core 5 vertically is provided with driving shaft 7, soft iron core 6 is sleeved on the driving shaft 7, its bottom is fixed with moving iron core 5, and the outside of soft iron core 6 is provided with cannelure, and coil 4 is set in the groove; The upper port of casing 8 is provided with the porose cover plate in center 2, is fixed with annular permanent magnet 3 on the bottom surface of cover plate 2; Tripping spring 1 is set on the driving shaft 7, and the upper end of driving shaft 7 is connected with excess of stroke tube 18.
The utility model operation principle is as follows:
As shown in Figure 4, when the utility model closes a floodgate, in the coil 4 of Monostable permanent magnetic mechanism 14, pass to the switching current of specific direction, this electric current produces on soft iron core 6 and identical magnetic field, permanent magnet 3 magnetic fields, magnetic attraction between soft iron core 6 and the permanent magnet 3 is increased, make soft iron core 6 drive moving iron core 5 and driving shaft 7 moves upward, and with permanent magnet 3 adhesives; The driving shaft 7 that moves upward promotes insulating bar 17 by excess of stroke tube 18, and actuating vacuum interrupter 9 is realized closing a floodgate.At this moment, because driving shaft 7 moves upward, make tripping spring 1 pressurized, for separating brake has been laid in energy.
During the utility model separating brake, in the coil 4 of Monostable permanent magnetic mechanism 14, pass to the electric current opposite with the switching current direction, this electric current produces on soft iron core 6 and opposite magnetic field, permanent magnet 3 magnetic fields, magnetic between soft iron core 6 and the permanent magnet 3 is reduced, under the elastic force effect of tripping spring 1, soft iron core 6 is separated with permanent magnet 3, and iron core 5 is moved in promotion and driving shaft 7 moves downward, the driving shaft 7 that moves downward is by excess of stroke tube 18 pulling insulating bars 17, and actuating vacuum interrupter 9 is realized separating brake.In above-mentioned divide-shut brake process, moving up and down of insulating bar 17 rotated switch rotating shaft 20 by tooth bar 22 and the gear 21 that is arranged on the auxiliary switch 19, thereby driven the make and break of auxiliary switch 19.
