Abstract
A vacuum permanent magnetic outdoor high-voltage circuit breaker is a high voltage electrical device, and comprises a vacuum arc-extinguishing device, an insulating post and a drive device in sequence connection. A vacuum arc-extinguishing chamber is disposed inside an arc-extinguishing chamber porcelain insulator in the vacuum arc-extinguishing device and embedded on the upper end of a seat in the arc-extinguishing chamber. An insulating pull rod in the insulating post is disposed in a post porcelain insulator. In the drive device, a base seat box is provided with a control mechanism, which is fixed below a base seat bracket. And the insulating post is fixed above the base seat bracket. The lower end of the insulating pull rod is connected with the control mechanism by a flexible connector. The insulating pull rod is connected with a moving contact point of the vacuum arc-extinguishing chamber through the upper part of the post porcelain insulator. The vacuum arc-extinguishing chamber is connected with a connecting seat by an insulating post. The utility model has advantages of light weight, less movable components and high whole reliability.
Description
One, technical field:
The utility model is a kind of ac hv breaker, belongs to the technical field that high voltage electric equipment is made.
Two, background technology:
The primary cut-out of existing 40.5kV, all adopt spring operating mechanism or electromagnetic operating mechanism, because the movable member of these two kinds of mechanisms is many, mechanical drive train is loaded down with trivial details, makes because the switch fault probability that operating mechanism causes is very high, so the reliability of sleeve mechanism is low, the maintenance rate height, and energy consumption is many, and noise is big, the Switch main body quality is about 800～1000 kilograms, and is relatively heavier.The vacuum circuit-breaker of present identical electric pressure is the dry construction that does not have the no SF6 of oil between fracture internal surface of sleeve pipe and vacuum extinction chamber enclosure, and the condensation phenomenon happens occasionally, and causes in some cases, and circuit breaker can not normally cut-off.
Three, summary of the invention:
(1) goal of the invention
Goal of the invention of the present utility model provides a kind of quality that as far as possible reduces moving part, alleviates Switch main body weight, realizes single-phase controllable operating and improves the vacuum and permanent magnet outdoor AC high-voltage circuit breaker of the reliability of whole mechanism.
(2) technical scheme
The utility model is a kind of vacuum and permanent magnet outdoor AC high-voltage circuit breaker, formed by driving mechanism and actuator's two parts, this circuit breaker is linked in sequence and is formed by vacuum arc-extinguishing device, insulation column, three parts of drive unit, in the arc control device porcelain vase in vacuum arc-extinguishing device is vacuum interrupter, embeds the upper end that seat is positioned at the arc control device porcelain vase; Insulated tension pole in the insulation column is arranged in support insulator; In drive unit, be provided with operating mechanism in the base member case, operating mechanism is fixed on the bottom of base support, insulation column be fixed on base support above, the lower end of insulated tension pole joins by flexible jumper and operating mechanism, insulated tension pole passes its top of support insulator and is connected with the moving contact of vacuum interrupter, the top and bottom of support insulator mesopore be respectively equipped with increase climb umbrella and under increase and climb umbrella; Be filled with solid-state silica gel between arc control device porcelain vase inwall and the vacuum extinction chamber enclosure.
The above is the phase structure of this circuit breaker, and whole breaker body is by three single-phase compositions, and realizes the three-phase interlock by secondary.
(3) technique effect
35kV vacuum and permanent magnet outdoor AC high-voltage circuit breaker is except the basic fundamental performance with like product in the past, because adapted permanent-magnet manipulating mechanism, form best fit complete operation function with vacuum interrupter, movable member is from up to a hundred, reduce to twenties, the mechanical breakdown probability reduces about 60%, so overall structure reliability height can carry out 10,000 operations and the Maintenance free maintenance.While Switch main body lighter weight, single-phase have only about 160 kilograms.Between arc control device porcelain vase and vacuum extinction chamber enclosure, adopt and fill solid-state silica gel, can prevent condensation fully.The support insulator inwall is taked to increase twice and is increased and climb full skirt, guarantees still can normally move in serious condensation condition.
This product is applicable to that rated voltage is 40.5KV, and rated frequency is the three-phase ac power system of 50HZ, is used for branch, closes load current, and overload and short circuit current also can carry out frequent operation or repeatedly cut-off in the rated current scope.Single-phase product also can be applicable to the control of electric railway traction.The core component of circuit breaker has extensive applicability, can be used in the breaker apparatus of different electric pressures.
Four, description of drawings
Fig. 1 is a general structure schematic diagram of the present utility model, vacuum arc-extinguishing device 1 wherein arranged, embed seat 11, arc control device porcelain vase 12, vacuum interrupter 13, Connection Block 14, moving contact 131, insulation column 2, insulated tension pole 21, support insulator 22, on increase and climb umbrella 23, increase and climb umbrella 24, drive unit 3, base support 31, flexible jumper 32, operating mechanism 33, base member case 34 down.
Five, embodiment
Single-phase circuit breaker integral body is made up of three parts, is vacuum arc-extinguishing device 1, insulation column 2 and drive unit 3 successively from the beginning of structure upper end.Vacuum arc-extinguishing device 1 is formed by embedding seat 11, arc control device porcelain vase 12, vacuum interrupter 13 and being connected aluminium seat 14 4 parts, wherein parts embed seat 11, in vacuum interrupter 13 was in arc control device porcelain vase 12 and is connected the insulator that aluminium seat 14 constitutes, vacuum interrupter 13 was fixed on the arc control device porcelain vase 12 by embedding seat 11.Simultaneously vacuum extinction chamber device 1 constitutes outsides with the support insulator 21 of insulation column 2 and is connected by connecting aluminium seat 14, and 13 of inner vacuum arc control device link together by screw thread and insulated tension pole 21.It below insulation column 2 drive unit 3 that operating mechanism 33 (south is from head factory CPM1) is housed.Operating mechanism 33 is fixed on base support 31 belows, and carries out rectilinear motion by the flexible jumper 32 direct insulated tension poles 21 that drive.And the moving contact 131 that insulated tension pole will drive in the vacuum interrupter 13 is finished the given branch of user, is closed instruction.
Whenever the permanent-magnet manipulating mechanism that matches is taked the direct kind of drive, constitutes synchronous branch, closing operation by electric loop between the three-phase.Special increase creepage distance technology is taked in pillar sleeve inside, and promptly support insulator 21 inwalls are taked to increase twice and increased and climb full skirt and increase promptly and climb umbrella 23, increase down and climb umbrella 24 (being formed by the cast of SMC material), guarantee still can normally move in serious condensation condition.Make length have only the pillar sleeve inner surface creepage distance of 560mm to increase to 1000mm.
Circuit breaker adopts the column support type phase structure, and by three single-phase compositions, alternate mounting center is loaded on electric railway then for single-phase apart from being 600～650mm when being loaded on the electric power system three-phase structure.
The moving iron core of permanent-magnet manipulating mechanism takes Direct Action Type to be connected with the vacuum interrupter moving contact.Space between arc control device porcelain vase 12 inwalls and vacuum interrupter 13 shells is adopted and is filled solid-state silica gel, can prevent condensation fully.
