Embodiment
The invention mainly comprises main contact 1.1, secondary contact 1.2, insulating support 2, transition contact 3.
Embodiment 1：Accompanying drawing 1 is a kind of single resistor transition tapping switch movable contact component, in order to reduce the chi of shunting switch
Very little and saving material, main contact 1.1 are arranged in the diverse location of insulating support 2, this position with secondary contact 1.2, transition contact 3
Put corresponding with the position of static contact 5；Main contact 1.1 electrically connects with secondary contact 1.2, and is symmetrically arranged in the center of static contact 5
Plane；The width of main contact 1.1 and transition contact 3 is more than the width of secondary contact 1.2, the main contact 1.1 and mistake of this technical scheme
Although crossing width of the contact 3 more than known shunting switch respective contacts, the width of static contact 5 is much smaller than known shunting switch phase
The stationary contact head width answered, mutually n static contact, only one group of moving contact, therefore substantially reduce product are provided with because shunting switch is every
Cost；Main contact 1.1, transition contact 3 are staggeredly arranged；Main contact 1.1, secondary contact 1.2 and the no machinery insulated from each other of transition contact 3
Connection；Can be with transposition with transition contact 3 according to the requirement main contact 1.1 of transformer and secondary contact 1.2；Transition contact 3 to
It is less single-tap header structure, sees accompanying drawing 2.
The circuit theory of above-described embodiment is shown in Fig. 5, is the moving contact component of the present embodiment in chain-dotted line.
Embodiment 2：Accompanying drawing 3 is a kind of moving contact component of double resistor transition shunting switch, using point of this technical scheme
It is widely used to connect switch, a variety of requirements of transformer, the Breaking capacity of shunting switch each contact when switching gear can be met
Do not influenceed by electric network swim direction.One main circuit, two mistakes are specially set on insulating support 2 of the shunting switch per phase
Cross circuit, the transition contact 3 of the main contact 1.1 of main circuit, secondary contact 1.2 and transition circuit is arranged in insulating support 2
Diverse location, this position are corresponding with the position of static contact 5；Main contact 1.1 electrically connects with secondary contact 1.2, and is symmetrically arranged in
The central plane of corresponding static contact 5；In order to reduce the volume of shunting switch, reduce cost, the main contact on insulating support 2
1.1st, the position of secondary contact 1.2 is transversely provided with transition contact 3.1 and transition contact 3.2, and main contact 1.1, transition contact 3 stagger
Arrangement, is shown in accompanying drawing 4；Main contact 1.1, secondary contact 1.2, the upper-lower position of transition contact 3 can exchange；Main contact 1.1 and pair are touched
First 1.2 with transition contact 3.1, the no mechanical connection insulated from each other of transition contact 3.2；Transition contact 3.1 and transition contact 3.2 are at least
Using single-tap header structure；The width of main contact 1.1 and transition contact 3 is more than the width of secondary contact 1.2, and the master of this technical scheme touches
Although first 1.1 and transition contact 3 more than the width of known shunting switch respective contacts, the width of static contact 5 is much smaller than known
The corresponding stationary contact head width of shunting switch, mutually n static contact, only one group of moving contact, therefore greatly are provided with because shunting switch is every
It is big to reduce product cost；Circuit theory is shown in Fig. 6, is the moving contact component of the present embodiment in chain-dotted line.
Insulating support 2 in above-described embodiment is installed on the drive means, and during circuit conversion, drive device drives insulation branch
Frame 2 moves (straight line or circular motion) to a specified location, main contact 1.1, secondary contact 1.2, transition contact 3 in motion process
Contacted or separated with the static contact of relevant position by the program of setting, turned so as to complete the circuit in the case of bringing onto load is not powered off
Change.Due to potential difference between each static contact be present, therefore with the short circuit current in transition resistance R limiting circuit transfer processes.
The basic principles, principal features and advantages of the present invention have been shown and described above, the present invention is not by above-described embodiment
Limitation, on the premise of its general principles are not departed from the present invention also have multiple technologies scheme, these technical schemes all will
