Embodiment Construction

[0032] The content of the invention of the present invention will be further described below in conjunction with the accompanying drawings and embodiments.

[0033] like figure 1 As shown, the double moving iron core permanent magnet operating mechanism provided in this embodiment includes a guide rod 1, an active iron core 2, an auxiliary moving iron core 3, a static iron core 4, a permanent magnet 5, a coil 6, a first cover plate 7, and a second cover Plate 8, yoke 9, beam 10 and two opening springs 11.

[0034] The driving core 2, the auxiliary driving core 3 and the yoke 9 are all cylindrical. The first cover plate 7 is arranged on the top end of the magnetic yoke 9 , and the second cover plate 8 is arranged on the bottom end of the magnetic yoke 9 . The driving iron core 2 and the auxiliary driving iron core 3 are disposed in the inner cavity of the yoke 9 facing each other along the axial direction, and a second gap 16 is provided between the auxiliary driving iron cor...

Abstract

The invention discloses a double-acting iron core permanent magnet operating mechanism which comprises a guide rod (1), a primary iron core (2), a secondary iron core (3), a static iron core (4), a permanent magnet (5), a coil (6), a first cover plate (7), a second cover plate (8), a magnet yoke (9), a beam (10) and two breaking brake springs (11). The primary iron core (2), the secondary iron core (3) and the magnet yoke (9) are cylindrical, the first cover plate (7) is arranged on the top of the magnet yoke (9), and the second cover plate (8) is arranged at the bottom of the magnet yoke (9). Compared with a permanent magnet operation structure in the prior art, the double-acting iron core permanent magnet operating mechanism is little in switch-on current, rigid resultant velocity is obviously reduced, and rigid component velocity is increased obviously. Compared with a permanent magnet operation mechanism with a single movable iron core in the prior art, according to the double-acting iron core permanent magnet operating mechanism, the maximum current in the whole switch-on process is reduced by about 50%.

Description

technical field [0001] The invention relates to the technical field of intelligent electrical appliances in electric power systems, in particular to a double-acting iron core permanent magnet operating mechanism, which is used for a vacuum circuit breaker. Background technique [0002] As we all know, the operating mechanism of the circuit breaker is its main source of power, and the operating mechanism plays a vital role in the performance of the circuit breaker. In the prior art, the most common operating mechanism is a spring operating mechanism or an electromagnetic operating mechanism. The disadvantages of the spring operating mechanism and the electromagnetic operating mechanism are: complex structure, resulting in low stability and reliability; high energy consumption, resulting in high cost. [0003] In order to overcome the above-mentioned shortcomings of the spring operating mechanism and the electromagnetic operating mechanism, technicians have designed a permane...
