Description
Technical field
The utility model relates to a kind of isolated switchgear, particularly relates to a kind of indoor high-voltage solid insulation isolating switch.
Background technology
Existing indoor high-voltage solid insulation isolating switch comprises that three parallel three identical isolating switch bodies of installation.Wherein, the isolating switch body is made up of the switch component on top, the breaker assembly at middle part, the switch component of bottom, and the three processes integral type.Wherein, Switch component comprises cover-plate type isolating switch pedestal, embeds on the cover board enterprising output socket, localized immobilization back conductive seat, middle conductive seat, preceding conductive seat on the cover board; And the insulation screw mandrel in contact tube that can between conductive seat, slide and the screw-in contact tube is formed.Insulation screw mandrel rotating band moving conductive pipe moves.The state of conductive seat and middle conductive seat is for closing a floodgate after the contact tube cross-over connection, and the state of conductive seat and preceding conductive seat is separating brake or ground connection in the cross-over connection.Its shortcoming is that the isolating switch pedestal is the cover-plate type structure, therefore need when assembling with connector, carry out large-area sealing to installed surface, and poor sealing causes that humid air gets into the inner possibility of accident that causes and wants big; Switch component and middle part breaker assembly are all-in-one-piece up and down, and be inseparable, can not use separately, when not needing only needing isolating switch to use in the switch cubicle of circuit breaker, can cause the waste of breaker assembly, causes allocation plan dumb; Because back conductive seat, middle conductive seat, preceding conductive seat are that localized immobilization is on isolating switch pedestal cover plate; Carry out one-sided fixing; Therefore the crooked trend that produces arranged at work, therefore have generation, finally possibly cause the life-span to reduce than the possibility of quick-wearing conductive seat with the insulation screw mandrel; Because the isolating switch pedestal of three-phase is identical, a bus can not be staggered apart each other in the enterprising output socket position of A, B, C three-phase isolation switch body, so isolating switch inconvenience very when being connected with the three-phase main bus bar.
The utility model content
The purpose of the utility model is to overcome above-mentioned shortcoming, and a kind of good airproof performance is provided, and it is flexible to join the cabinet mode, and the conductive seat life-span is longer, and the low indoor high-voltage solid insulation isolating switch of cost.
The utility model indoor high-voltage solid insulation isolating switch comprises the isolated Switch main body of A, the isolated Switch main body of B and the isolated Switch main body of C of parallel installation, and the enterprising output socket of this three-phase isolation switch is dislocation arrangement.Wherein, the isolating switch body comprises the fixed sealing type pedestal, embeds the enterprising output socket in the pedestal; Seal the annular back conductive seat that is fixed in the pedestal chamber and is connected with enterprising output socket; Seal in the annular that is fixed in the pedestal chamber conductive seat before conductive seat and the annular, the following turnover line socket that is connected with middle conductive seat, be arranged in the pedestal chamber and with afterwards, in, the contact tube that is slidingly matched of preceding conductive seat; Be arranged on the nut in contact tube one end; The one of which end cooperates with nut, and the other end is supported on the insulation screw mandrel in the bearing, and the ground connection copper bar that is connected with preceding conductive seat.
The operation principle of the utility model indoor high-voltage solid insulation isolating switch is an insulation screw mandrel when rotatablely moving, and drives the contact tube horizontal movement, make its respectively with the back, in, preceding conduction seated connection touches.During combined floodgate, when insulation screw mandrel drive contact tube moves between middle conductive seat and the back conductive seat.Enterprising output socket, back conductive seat, contact tube, middle conductive seat, pass in and out line socket down and form conductive path; During separating brake, when conductive seat reached between the preceding conductive seat during insulation screw mandrel drive contact tube moved to, do not had contact tube between back conductive seat and middle conductive seat, formed isolation fracture; Before conductive seat through ground connection copper bar and the earth UNICOM, behind the isolating switch separating brake, isolating switch turnover line socket, middle conductive seat, contact tube, preceding conductive seat, ground connection copper bar down then forms conductive path, has realized the grounding function of line loop and ground connection.
The advantage of the utility model indoor high-voltage solid insulation isolating switch is (1) because the isolating switch body has adopted the fixed sealing type pedestal, good airproof performance, and it is inner to prevent that extraneous humid air from getting into, and uses more safe and reliable.(2) isolating switch this increased time turnover line socket 8 in stopping, both can use separately, can use with the breaker assembly combination again, it is flexible and cost is low to join the cabinet scheme.(3) fixing around back conductive seat, middle conductive seat, the preceding conductive seat in the isolating switch body for sealing, do not have in the work and produce crooked trend, reduce the wearing and tearing of conductive seat with the insulation screw mandrel, the life-span is longer.(4) the enterprising output socket of three-phase isolation switch body is dislocation arrangement, and the certain distance that staggered each other connects very convenient with the interior three-phase main bus bar parallel to each other of switch cubicle during assembling.Be mainly used in 10kV, the indoor switchgear of 50Hz three-phase alternating current.
