Embodiment:
The present invention is further described below in conjunction with drawings and Examples.
Shown in Figure 1A and Figure 1B, be a kind of electric isolating switch, form by fixed contact 1, dynamic/static contact 2, link insulator 3, supporting insulator 4, angle-iron frame 5, motor-operating mechanism 6, rotation axis 7, manual operation handle 8, stop 9, terminal block 11.
Wherein, three moving contacts of described three-phase isolation switch connect three active pull rod insulators of three-phase respectively, and three active pull rod insulators are connected with rotation axis, and the electric operating handle on the rotation axis connects motor-operating mechanism.
When the motor-operating mechanism of described three-phase isolation switch acquires the transmission or not signal, the motor of motor-operating mechanism gets electric operation, and drive pinion, worm gear pole, gear wheel rotate, when running reaches the action of assigned position sensitive switch, motor power is disconnected the motor stall.Isolating switch is carried out in accordance with regulations automatic branch, closing operation.
As shown in Figure 2, be the rotation shaft structure of isolating switch, rotation axis is fixed on the angle-iron frame, and 10 is the electric operating handle; The motor-operating mechanism of described three-phase isolation switch is connected with electric operating handle 10, and the electric operating handle connects rotation axis, rotation axis cylinder lever connecting rod insulator, and link insulator connects three moving contacts.8 is three-phase isolation switch manual operation handle.
