Abstract
The utility model provides a 126 kV outdoor AC high-voltage isolation switch, wherein the bearing seats of both ends of the base of the isolation switch are respectively and fixedly provided with a post insulator, the two post insulators are provided with a wire incoming end and a wire outgoing end respectively, between the two post insulators there are provided a contact end and a contact finger end, the contact end and the contact finger end are contacted with each other through a conductive tube, and the lower portion between the two post insulators is provided with a between-post pull rod in a stagger manner to form a single-pole isolation switch. The isolation switch can be used as a three-phase AC 50 Hz outdoor high-voltage electrical equipment, can perform switching operation when high-voltage lines are under the condition of being free of carrying current, and can realize the electrical isolation of a high-voltage bus to be troubleshot and a breaker, etc., thereby ensuring the normal power supply and avoiding accident occurrence. The isolation switch is simple in structure, reliable in performance, easy in mounting and adjusting, and safe and convenient in maintenance and troubleshooting.
Description
Technical field
The utility model relates to a kind of 126kV outdoor AC high-voltage isolating switch, switches under no current-carrying situation at high-tension line, to realized the electrical isolation of safety by the high voltage bus that overhauled, circuit breaker etc.
Background technology
The ac high-voltage isolating switch is the necessary product of the normal operation of electric railway traction power transformation system, and deciliter task that it is being born in the immunization with gD DNA vaccine line is the capital equipment that guarantees traction substation of electric railway and the normal operation of contact net system.At present, existing outdoor high-voltage isolating switch product is not enough below existing on the market: conducting system complex structure, poor reliability, maintenance difficult, isolating switch current-carrying part all are full copper electric-conductors, have wasted a large amount of copper resources, have increased the manufacturing cost of product.
Summary of the invention
To structural deficiency in the prior art; The purpose of the utility model provides a kind of 126kV outdoor AC high-voltage isolating switch; Guarantee that high-tension line switches and the high voltage bus to being overhauled under no current-carrying situation; Circuit breakers etc. are realized the electrical isolation of safety, and claimed structure is simple, reduces production costs.
For realizing above-mentioned purpose; The technical scheme that the utility model adopts provides 126kV outdoor AC high-voltage isolating switch; This isolating switch includes base, post insulator, contact end, fingertip end, end of incoming cables, leading-out terminal bearing pedestal, alternate pull bar, intercolumniation pull bar; Wherein: on the bearing pedestal at said base two ends, be fixed with post insulator respectively, end of incoming cables, leading-out terminal are housed respectively on two post insulators, in the middle of two post insulators, be provided with contact end, fingertip end; Contact end, fingertip end contact through contact tube, and the bottom dislocation between two post insulators is provided with the intercolumniation pull bar and forms single-pole isolator.
Effect of the present invention is that this isolating switch is a three-phase alternating current 50Hz outdoor high-voltage electric equipment; Supply high-tension line under no current-carrying situation, to switch and high voltage bus to being overhauled; Circuit breakers etc. are realized the electrical isolation of safety, guarantee normal power supply, avoid accident to take place.That this isolating switch has is simple in structure, dependable performance, be easy to install adjustment, Maintenance and Repair safe ready, advantage such as applied widely.Because this product primacy and economy on the price technically determined that this product must produce good social benefit, specifically may be embodied in following some:
1, electric-conductor copper-aluminium transition form replaces original full copper electric-conductor, not only reduces the production cost of the isolating switch of knowing clearly, and has also practiced thrift a large amount of copper resources for country.
2, compare with other same device, this isolating switch bearing pedestal and base flange plate physical dimension diminish.Be easy to install adjustment, Maintenance and Repair safe ready, reduce system's operation cost.
Description of drawings
Fig. 1 is the isolating switch structure vertical view of the utility model;
Fig. 2 is the isolating switch structural front view of the utility model.
Among the figure:
1, base 2, post insulator 3, contact end 4, fingertip end 5, end of incoming cables
6, leading-out terminal 7, bearing pedestal 8, alternate pull bar 9, intercolumniation pull bar
Embodiment
In conjunction with accompanying drawing the 126kV outdoor AC high-voltage isolating switch structure and the operation logic of the utility model are explained.
Like Fig. 1, shown in Figure 2; The utility model 126kV outdoor AC high-voltage isolating switch structure; This isolating switch includes base 1, post insulator 2, contact end 3, fingertip end 4, end of incoming cables 5, leading-out terminal 6 bearing pedestals 7, alternate pull bar 8, intercolumniation pull bar 9; End of incoming cables 5, leading-out terminal 6 are housed being fixed with respectively on the bearing pedestal 7 at said base 1 two ends on post insulator 2, two post insulators 2 respectively, in the middle of two post insulators 2, are provided with contact end 3, fingertip ends 4; Contact end 3, fingertip end 4 contact through contact tube, and the bottom dislocation between two post insulators 2 is provided with intercolumniation pull bar 9 and forms single-pole isolator.
Three groups arranged side by side of said single-pole isolator becomes three-pole isolator, and the bottom dislocation between two post insulators 2 is provided with intercolumniation pull bar 9, is provided with alternate pull bar 8 between per two utmost point single-pole isolators and is connected with the bearing pedestal 7 of each single-pole isolator.Said single-pole isolator transmission be the bearing pedestal 7 on the console switch base 1, form the isolating switch of double-column horizontal rotation type.
The electric-conductor copper-aluminium transition form of the utility model 126kV outdoor AC high-voltage isolating switch replaces original full copper electric-conductor, and electric-conductor is except that contact end 3, fingertip end 4, and remainder is full aluminium electric-conductor.
Operation logic is: said single-pole isolator transmission be the bearing pedestal 7 on the console switch base 1; Post insulator 2 rotation axiss of a side turn clockwise 90 ° on the bearing pedestal 7; The post insulator 2 that intercolumniation pull bar 9 through 2 of two post insulators drives opposite sides is to being rotated counterclockwise 90 °, makes the conduction plug-in strip separately or closed.Single-pole isolator is listed as parallel three consists of three-pole isolator; Be connected with the bearing pedestal 7 of single-pole isolator through alternate pull bar 8 between the single-pole isolator; Operate the bearing pedestal 7 on arbitrary single-pole isolator base 1, alternate pull bar 8 other the two poles of the earth isolating switches of drive are done and are synchronized with the movement.
The structure of the utility model 126kV outdoor AC high-voltage isolating switch has improved the isolating switch quality, makes electric-conductor be implemented to copper-aluminium transition from full copper spare, and has guaranteed the quality of main electric-conductor from technical matters.
