Abstract
The utility model discloses a crankarm permanent magnet breaker which comprises a box body, a permanent magnet mechanism arranged in the box body and a three-phase vacuum arc extinguish chamber arranged on the box body, and is characterized in that a drive pull rod is arranged below the permanent magnet mechanism; the permanent magnet mechanism is connected with a drive crankarm through a waist hole and connected with the drive pull rod through the drive crankarm; the drive pull rod is provided with a plurality of positioning holes and connected with a pull rod of the three-phase vacuum arc extinguish chamber through the positioning holes; and the drive crankarm is provided with a crankarm drive pin which is inserted into the positioning hole of the drive pull rod. The breaker has novel structure, adopts the driving mode of the drive crankarm to replace the original the direct connection mode of the driving rod, is convenient in use, saves time and effort, and effectively improves the work efficiency.
Description
Technical field
The utility model relates to circuit breaker, particularly a kind of bent-arm permanent-magnet breaker.
Background technology
Permanent-magnet breaker is very extensive in industrial application, Figure 1 shows that the domestic permanent-magnet breaker transmission diagram that generally uses, the circuit breaker model is the ZW32 type, permanent magnet mechanism (01) is the direct coupled structure that adopts a drive link (02) with three-phase vacuum interrupter (04), and the defective that this structure exists is as follows:
I, permanent magnet mechanism (01) diameter arrive the cabinet base distance greater than drive link (02) center, concentric for satisfying drive link (02) with permanent magnet mechanism (01) motion parts, need increase casing, perhaps reduce supporting base, because these all are Standard Module production, change trouble, be unfavorable for quick production.
II, three-phase vacuum interrupter (04) is in nature and just closes the position, and permanent magnet mechanism (01) is because the magnetic attraction effect, be in closing position, the closing retention force of permanent magnet mechanism (01) is general all about 4500N, if the location hole that this moment pull bar (03) of three-phase vacuum interrupter (04) is suspended on the drive link (02) of permanent magnet mechanism (01) is the work that bothers very much, generally three-phase vacuum interrupter (04) firmly need be compressed to closing position respectively could hang over its pull bar (03) on the drive link (02), just close the position and need the power of 4500N nearly and the drive link (02) of permanent magnet mechanism (01) shifted onto from combined floodgate, very difficult.And the parameter adjustment of breaker apparatus repetitive process often needs constantly to adjust the pull bar (03) of three-phase vacuum interrupters (04), like this efficiency of assembling and precision is brought very big influence, is unfavorable for the debugging assembling of producing.
The utility model content
In order to overcome the defective that above-mentioned prior art exists, the utility model provides a kind of bent-arm permanent-magnet breaker, adopts the drive link direct-connected mode of the kind of drive that drives connecting lever before replacing, and is easy to use, during laborsaving joint, effectively improved operating efficiency.
The technical solution of the utility model is as follows:
The bent-arm permanent-magnet breaker comprises casing, is arranged on permanent magnet mechanism, the three-phase vacuum interrupter on the casing in the casing and is positioned at the drive stay of described permanent magnet mechanism below.
The pull bar of described three-phase vacuum interrupter is connected on the location hole of the described drive stay that is positioned at permanent magnet mechanism below, and described drive stay is connected at the pull bar of nature with the three-phase vacuum interrupter.
Further, described permanent magnet mechanism is fixed under the cabinet base, and permanent magnet mechanism adopts the waist hole to connect one and drives connecting lever;
Permanent magnet mechanism is connected with above-mentioned drive stay by above-mentioned driving connecting lever again, drive on the connecting lever connecting lever trundle is set, during the debug circuit breaker device parameter, permanent magnet mechanism need not be dismantled, only described connecting lever trundle and drive stay need be removed, remove described drive stay and just can conveniently debug.
During use, promote above-mentioned drive stay to the combined floodgate side shifting, owing to adopt lever principle, than a lot of easily with the vertical compression arc control device of pre-structure, directly promote drive stay and be drive link behind closing position, hang up the trundle of described driving connecting lever, promptly finished the installation of permanent magnet mechanism, time saving and energy saving, convenient and swift.
The beneficial effects of the utility model are, novel structure adopts the kind of drive of bent-arm structure, uses lever principle, and time saving and energy saving, the debugging that helps producing is installed, and has effectively improved operating efficiency.
Description of drawings
Fig. 1 is the drive mechanism figure of the existing permanent-magnet breaker that generally uses.
Fig. 2 is a structural representation of the present utility model.
Embodiment
For technological means, creation characteristic that the utility model is realized, reach purpose and effect is easy to understand, below in conjunction with embodiment, further set forth the utility model.
Embodiment:
As shown in Figure 1, be the existing permanent-magnet breaker transmission diagram that generally uses, employing be the direct-connected structure of a drive link, when adjusting the parameter of breaker apparatus, unusual effort and inconvenient; Permanent magnet mechanism 01 diameter to the cabinet base distance, requires drive link 02 concentric with permanent magnet mechanism 01 motion parts greater than drive link 02 center during use, need increase casing, perhaps reduces supporting base, because these all are Standard Module production, changes trouble.
Referring to Fig. 2, a kind of bent-arm permanent-magnet breaker of the utility model comprises casing 4, is arranged on permanent magnet mechanism 1, the three-phase vacuum interrupter 5 on the casing 4 in the casing and is positioned at the drive stay 3 of described permanent magnet mechanism 1 below.
Wherein, drive stay 3 is equivalent to the drive link 02 shown in Fig. 1, and its effect is identical.
During debugging permanent-magnet breaker device parameter, permanent magnet mechanism 1 need not be dismantled, and only described connecting lever trundle 21 need be removed with drive stay 3, removes described drive stay 3 and just can conveniently debug.
During use, promote above-mentioned drive stay 3 to the combined floodgate side shifting, owing to adopt lever principle, than a lot of easily with the vertical compression arc control device of pre-structure, directly promote drive stay 3 and be drive link behind closing position, hang up the trundle 21 of described driving connecting lever, promptly finished the installation of permanent magnet mechanism 1, time saving and energy saving, convenient and swift.
More than show and described basic principle of the present utility model, principal character and advantage of the present utility model.The technical staff of the industry should understand; the utility model is not restricted to the described embodiments; that describes in the foregoing description and the specification just illustrates principle of the present utility model; the utility model also has various changes and modifications under the prerequisite that does not break away from the utility model spirit and scope, and these changes and improvements all fall in claimed the utility model scope.The claimed scope of the utility model is defined by appending claims and equivalent thereof.
