Description
The utility model relates to the corollary equipment of power system transformer substation, is a kind of outdoor high-voltage isolating switch.
Isolating switch mainly is used for cutting off circuit, and obvious visible fracture is arranged under the disjunction state, close state in the pass under, conducting system can be by the short circuit current of normal operating current and fault.
Existing this series products existence ground cutter and the alternate drive mechanism complexity of ground cutter, cost height, isolating switch is the plug-type shortcoming of two-step action.
The utility model provides a kind of improved outdoor high-voltage isolating switch, and it can stablize, safely, promptly realize alternate synchronous branch, combined floodgate that operation is steadily reliable.
The utility model is achieved through the following technical solutions: it is by the three pillar type porcelain vase, conduction part and grounded parts are formed, conduction is partly by the operator of the conduction on the porcelain vase in the middle of being installed in bar, the operator static contact seat and the outlet board of side porcelain vase upper end constitute, grounded parts is by a left side that is connected underframe main body both sides, ground cutter static contact seat on right ground knife bar and the porcelain vase constitutes, feature structure: middle porcelain vase is installed on the underframe through bearing pedestal, be connected with flap on the bearing pedestal, three alternate middle porcelain vases link to each other with same operator kinematic link by its flap and constitute the operator of three utmost point coordinated types, and the homonymy ground cutter of phase inter-stage is connected in the ground knife bar rotating shaft and constitutes three utmost point coordinated type ground cuttves.
Described operator static contact seat and ground cutter static contact seat hold together, and the operator static contact seat comprises the conductive pole that links to each other with porcelain vase, the clamp-type static contact that cooperates with conducting rod termination contact block and operator static contact seat cover, is associated with torsion spring between seat cover and the conductive pole; Ground cutter static contact seat comprises touch base cover and the fixing clamp-type static contact that cooperates with ground knife bar end contact block within it, during combined floodgate, the termination of conduction operator bar is inserted in the operator static contact seat and is contacted with static contact, and during separating brake, the termination of ground knife bar is inserted in the ground cutter static contact seat and contacted with the clamp-type static contact.
Described isolating switch spaced apart is not less than 2000mm, and single-phase two ends porcelain vase centre-to-centre spacing is not less than 2400mm, and the porcelain vase height is 1500mm, and creepage ratio is apart from being not less than 28mm/KV.
The product that the utility model provides is applicable to rated voltage 145KV, the outdoor high-voltage electrical equipment of three-phase alternating current 50Hz, the zero load time-division of voltage being arranged, closing circuit usefulness for transformer station, is the pressure-air external insulation formula combined electrical apparatus transformer station corollary apparatus that compact can be prefabricated.
Below in conjunction with embodiment and accompanying drawing thereof utility model is described further.
Fig. 1 is the contour structures schematic diagram of the utility model embodiment.Fig. 2 is the vertical view of Fig. 1.
Fig. 3 is operator static contact seat and the ground cutter static contact seat structural representation that fuses.
Fig. 4 is the A-A cutaway view of Fig. 3.
As Fig. 1, shown in 2, the utility model is three post horizontal rotation type structures, is made up of underframe 4, bar type support insulator 2, conduction part and grounded parts.Underframe 4 is a channel-section steel, and respectively there is a fixing porcelain vase at the channel-section steel two ends, and middle porcelain vase is installed on the channel-section steel through bearing pedestal, and the flap 6 on the bearing pedestal can rotate flexibly, and porcelain vase is in company with turning an angle in the middle of driving.
Conduction comprises that partly conduction operator bar 11, operator static contact seat 1 and outlet board 9 constitute.Middle porcelain vase is alternate with middle porcelain vase to be connected on the operator connecting rod 12 by corresponding flap.
Grounded parts is made of left and right ground knife bar 3 that is connected the channel-section steel two ends and ground cutter static contact seat 10, and the phase that is positioned at the same side cutter indirectly is connected in the same ground knife bar rotating shaft 13.Ground connection form of the present utility model has two ground connection, single ground connection and earth-free.Single ground connection is arranged in right-hand member, and two ground connection are arranged in two ends, the channel-section steel left and right sides.
Fig. 3, shown in 4, operator static contact seat and ground cutter static contact seat connect the face one, comprise conductive pole 14, operator static contact seat cover 15, clamp-type static contact 16, cutter static contact seat cover 17, compression spring 18, torsion spring 19 form.
Operating principle: when 5 actuatings of operator operating mechanism, drive flap 8 by the operator kinematic link, make the middle porcelain vase that is attached thereto rotate 75 °, the conducting rod of its upper end separates with moving contact seat thereupon or is closed, thereby realizes branch, the combined floodgate of isolating switch.When conducting rod carries out branch, when closing a floodgate, drives two concavo-convex interlock plates by the interlocking kinematic link and realize release or interlockings, guarantee earthed switch and operator switch can only close by main branchs → ground → circular order that ground branch → master closed → led branch operates.
The operating mechanism that this isolating switch adopts CJ6 type electrically operated institution to divide, close a floodgate as the control operator, the also available handle of this mechanism carries out manual operation; Ground cutter control switch 7 adopts the control of CS11G-I type hand-power operating mechanism.
When isolating switch closes a floodgate, conduction operator bar 11 turns clockwise with middle porcelain vase 2, the contact block at bar two ends applies inner rotary power to operator static contact seat cover 15 along continuous straight runs, driving operator static contact seat 1 overcomes the active force of torsion spring 19 and rotates an angle, contact block on the conduction operator bar is inserted in the seat cover flexibly, swimmingly contact with contact 16 and realize that operator closes a floodgate, the two mutual pressured spring 18 that contracts of degree of tightness that contacts is regulated automatically.When operator was closed a floodgate, ground cutter static contact seat 10 did not rotate.
When the isolating switch separating brake, conduction operator bar reverse rotation and touch base separating brake, hand-power actuating ground cutter control switch 7, three utmost point coordinated type ground knife bar rotating shafts 13 this moment insert in the ground cutter static contact seat ground cutter of three-phase in company with rotating simultaneously smoothly, realize that the ground cutter closes a floodgate.
Cutter alternate drive mechanism in the utility model ground is squeezed into the formula structure for one step of ground cutter, and structure is compact more, has reduced manufacturing cost.Since increased creepage ratio distance, porcelain vase centre-to-centre spacing and alternate centre-to-centre spacing, rationally distributed, make product design succinct, lines are lucid and lively.Security of operation, reliable, easy to maintenance.
