Abstract

The invention provides an operating device for a rapid mechanism switch. The device comprises a shell, a transmission rod, an electromagnetic driving mechanism and a permanent-magnet driving mechanism, wherein the electromagnetic driving mechanism and the permanent-magnet driving mechanism are arranged in the shell, the transmission rod penetrates through the shell in a sliding way, a movable contact is arranged at an upper end of the transmission rod, the permanent-magnet driving mechanism is connected with the transmission rod and is used for driving the transmission rod to upwards move so that the movable contact is in contact with a static contact, and the electromagnetic driving mechanism is connected with the transmission rod and is used for driving the transmission rod to downwards move so that the movable contact is separated from the static contact. In the device, the electromagnetic driving mechanism and the permanent-magnet driving device are arranged, thus, the breaking-closing speed can be greatly increased, and the breaking-closing time is shortened; and moreover, the device is simple in structure and is easy to operate.

Description

technical field [0001] The invention relates to the technical field of switches, in particular to an operating device for a fast mechanical switch. Background technique [0002] At present, the fast vacuum switch based on the electromagnetic repulsion mechanism has simple structure, fast opening and closing speed, and small on-state loss. with broadly application foreground. [0003] The existing rapid vacuum switch of the electromagnetic repulsion mechanism generally adopts a coil-metal disc type operating mechanism, such as figure 1 As shown, the working principle: the capacitor discharges to the opening coil 1' or the closing coil 2', so that the opening coil 1' or the closing coil 2' generates a pulse current, and the pulse current forms a pulsed magnetic field, which is set in the opening coil 1 The metal disc 3' between 'and the closing coil 2' senses the pulse current to generate eddy current, and the eddy current interacts with the pulse current to generate electro...
