Four angles of the upper and lower discharge coil of described closing holding mechanism, separating brake maintaining body, eddy current repulsive force mechanism have circular hole, and with four bolts through four holes, said mechanism are fixed on base body.
The switching magnet of described fixed permanent magnet fixes skeleton and separating brake magnet fixes the gap leaving 0.2mm between the bottom of skeleton and permanent magnet, when preventing from keeping suction disc motion direct collision to permanent magnet, because energy is too large, may break permanent magnet; Also prevent from keeping suction disc directly to contact with permanent magnet simultaneously, magnet may be pulled out separately time.
Described maintenance suction disc is circular configuration.
Coil support rod is provided with between described eddy-current disc and closing line girth sheets.
Described splitting lock cushioning mechanism directly contacts with axis screw rod, and splitting lock cushioning mechanism is made up of butterfly spring and butterfly spring locking member, and butterfly spring is installed on locking member inside.
Described combined floodgate buffer gear and insulated tension pole are as one, and for entity can bear overvoltage insulation before this mechanism, latter half inside is hollow, the butterfly spring of in-built buffering.
The invention has the beneficial effects as follows:
1, change the four-pole permanent magnet iron be originally installed on iron plate into hexapole permanent magnet, and arrange according to hexahedral arrangement, every block permanent magnet makes sector structure.
2, for reducing the larger impact on suction of leakage field, original steel plate is encased magnet and change the skeleton making fixed permanent magnet with non-magnetic austenitic stainless steel into, stainless steel insert is fixed with an iron plate in top, makes permanent magnet form magnetic loop.
3, for preventing motion from colliding damage permanent magnet time, collide part joint portion in stainless steel insert fixed permanent magnet part and suction disc, be designed with the anti-collision clearance between poles of 0.2mm, when making collision, active force all acts on stainless steel insert, can not damage permanent magnet.
4, for making maintenance suction disc stress equalization, original suction disc is changed into circular configuration by square structure.
5, for preventing switch sub-switching operation time, because the excessive elastic collision energy of impulsive force discharges nowhere, make mechanism's contingent separating brake that rebounds unsuccessful, in the bottom of axis connecting rod, devise the buffer gear of a set of disc spring type, to shift kinetic energy, reduce lifting force, ensure that the stable of separating brake completes.
