Detailed description of the invention
Fig. 1 is the structural schematic diagram of the utility model embodiment.
In figure: 1- permanent-magnet operating mechanism, 2- vertical connecting, 3- inlet-outlet line copper bar, 4- moving contact, 5- static contact, 6- pressure
Plate, 7- rag iron spring, 8- pressing plate shaft, 9- static contact assembly.
Specific embodiment
In the following with reference to the drawings and specific embodiments, the utility model is described further.
As shown in Figure 1, a kind of high reliability magneto Aftercurrent protecting equipment touching disclosed in the utility model embodiment
Header structure, mainly by permanent-magnet operating mechanism 1, vertical connecting 2, inlet-outlet line copper bar 3, moving contact 4, static contact 5, pressing plate 6, pressing plate
Spring 7, pressing plate shaft 8 and static contact assembly 9 form.
Permanent-magnet operating mechanism 1 mainly by electromagnetic coil, permanent magnet and permanent magnet group of drive rods at.Permanent-magnet operating mechanism 1
Electromagnetic coil is made of QA-1/130 polyester enamelled wire, and the permanent magnet of permanent-magnet operating mechanism 1 selects neodymium iron boron N33H permanent magnetic
Steel material, the working principle of permanent-magnet operating mechanism 1 are that induced magnetic field is generated by electromagnetic coil, which generates suction to permanent magnet
Gravitation, driving permanent magnet moves up and down, to drive permanent magnet drive rod synchronizing moving.Inlet-outlet line copper bar 3 is for connecting open circuit
Two end cable of device, constitutes A, B, C, N three-phase four-wire system major loop copper bar, and the contact part downward bending of inlet-outlet line copper bar 3 is formed
Static contact 5.Vertical connecting 2 be clamped in 3 bending of two sides inlet-outlet line copper bar formation static contact 5 between, and can two sides into
It is moved up and down between the static contact 5 that 3 bending of outlet copper bar is formed, lower end and 4 phase of moving contact of vertical connecting 2 are fixed, vertically
The permanent magnet drive rod of the upper end connection permanent-magnet manipulating mechanism 1 of connecting rod 2, vertical connecting are made of insulating material.In this example
Vertical connecting 2 uses E font structure directed downwardly, and top cross bar is connected with the permanent magnet drive rod of permanent-magnet operating mechanism 1, every road
Vertical bar is separately connected a moving contact 4.
Permanent-magnet manipulating mechanism 1 is located at the top of vertical connecting 2 and is driven when permanent-magnet manipulating mechanism 1 acts by its permanent magnet
Lever drives vertical connecting 2 to move up and down, and then vertical connecting 2 drives all about 4 synchronizing movings of moving contact, works as permanent magnetism
When the permanent magnet drive rod of operating mechanism 1 is attracted upwards, vertical connecting 2 is driven to move up, to drive all moving contacts 4
To be formed by static contact 5 with 3 bending of inlet-outlet line copper bar of 2 two sides of vertical connecting respectively attracted at both ends, complete to close a floodgate dynamic
Make；
One end of pressing plate 6 is mounted on the pressing plate bearing of both ends by the erection of pressing plate shaft 8, and pressing plate bearing is fixed on and static contact
On connected static contact assembly 9, pressing plate 6 is rotated around pressing plate shaft 8, rag iron spring 7 is sleeved on pressing plate shaft 8, is pressed
Flat spring 7 acts on pressing plate 6, and provides downward elastic force for pressing plate 6, and the other end of pressing plate 6 is connected with vertical connecting 2,
And then rag iron spring 7 acts on the elastic force synchronous effect on pressing plate 6 in vertical connecting 2, when permanent-magnet manipulating mechanism 1 is inactive
When, pressing plate 6 is pushed by the way that rag iron spring 7 is synchronous so that moving contact 4 moves down, thus by 3 folding of moving contact 4 and inlet-outlet line copper bar
Bending at static contact 5 separate, complete separating brake movement.
