Abstract
The utility model relates to a corrugated pipe subassembly for a vacuum circuit breaker, which comprises a transmission shaft (1), a corrugated pipe (3), a corrugated pipe welding flange (2) and an mounting flange (6). The lower end of the corrugated pipe(3) is welded with the mounting flange (6) and the upper end of the corrugated pipe(3)is welded with the corrugated pipe welding flange (2). The transmission shaft (1)is welded together with the corrugated pipe, and a mounting hole is arranged on the mounting flange (6). The corrugated pipe subassembly is characterized in that an O-shaped ring groove is arranged on the upper head face of the mounting flange (6), and an O-shaped gasket ring (5) is arranged in the O-shaped ring groove. The corrugated pipe subassembly can realize airtight movable connection between an external mechanism and an internal arc extinguishing chamber of the vacuum circuit breaker, thus satisfying the requirements of a gas insulated switchgear.
Description
Technical field
The utility model relates to the vacuum circuit-breaker field, specifically, relates to a kind of vacuum circuit-breaker bellows component, belongs to inflate the important composition parts of cabinet with vacuum circuit-breaker in the High-Voltage Electrical Appliances.
Background technology
Existing inflation cabinet is that a kind of portion within it charges into the switch cubicle of gas as dielectric, and this has just had the requirement of sealing to switch cubicle.And vacuum circuit-breaker is an important moving component on the switch cubicle, do branch at circuit breaker, close a floodgate when moving, the main shaft rotation can transfer energy to vacuum interrupter, and in the inflation cabinet, must be sealed in the insulating gas as the vacuum interrupter of primary element, the breaker mechanism of front is to be placed on inflation cabinet outside, is convenient to regulate and safeguard; This just needs the parts with seal-moving function to connect breaker mechanism part and vacuum interrupter, thereby realizes whole branch, combined floodgate motion.And the seal-moving parts in the existing inflation cabinet adopt rubber seal to realize rotary seal mostly, have aging easily shortcoming.
Summary of the invention
The purpose of this utility model provides a kind of vacuum circuit-breaker bellows component that can realize that seal-moving is connected between the external agency and inner arc control device in the vacuum circuit-breaker.
The technical scheme that realizes above-mentioned purpose is: a kind of vacuum circuit-breaker bellows component, comprise power transmission shaft, bellows, bellows welded flange and mounting flange, the lower end of bellows and mounting flange welding, the upper end of bellows and the welding of bellows welded flange, power transmission shaft and bellows welded flange weld together, mounting flange is provided with installing hole, has " O " type ring recess on the upper surface of mounting flange, and is placed with " O " RunddichtringO in this " O " type ring recess.
After adopting technique scheme, the upper surface of mounting flange is leaned against on the mounting panel of circuit breaker, installing hole on the mounting flange is enclosed within on the double-screw bolt on the mounting panel, by nut and tight, the upper surface of mounting flange and mounting panel are closely pasted and, owing to have " O " type ring recess on the upper surface of mounting flange, and in this " O " type ring recess, be placed with " O " RunddichtringO, make cabinet internal gas and cabinet outside isolated, and the upper end of bellows component connects vacuum interrupter, the lower end connects mechanism's part of circuit breaker, thereby has realized that the seal-moving between the external agency and inner arc control device connects in the vacuum circuit-breaker.
Description of drawings
Fig. 1 is the utility model master TV structure schematic diagram;
Fig. 2 is the upward view of Fig. 1.
Embodiment
Below in conjunction with drawings and Examples the utility model is described in further detail.
As shown in Figure 1, 2, a kind of vacuum circuit-breaker bellows component, comprise power transmission shaft 1, bellows 3, bellows welded flange 2 and mounting flange 6, the lower end of bellows 3 and mounting flange 6 welding, the upper end of bellows 3 and 2 welding of bellows welded flange, power transmission shaft 1 welds together with bellows welded flange 2, and mounting flange 6 is provided with installing hole, have " O " type ring recess on the upper surface of mounting flange 6, and in this " O " type ring recess, be placed with " O " RunddichtringO 5.
As shown in Figure 1, on the mounting panel 4 of circuit breaker, have the hole that can allow bellows pass, be welded with double-screw bolt 7 around the hole, during installation, bellows component is passed the mounting panel 4 of circuit breaker, installing hole on the mounting flange 6 is enclosed within on the double-screw bolt 7, then mounting flange 6 is had a side of " O " RunddichtringO 5 to lean against on the circuit breaker mounting panel 4, with nut and tight.So just realize the moving component of inflation cabinet inside and being connected of inflation cabinet external movement parts, reached the requirement of gas insulation switch cabinet.
