Abstract

The invention discloses a super-fast operating mechanism for a high-voltage switch, which comprises a permanent magnetic position-keeping auxiliary drive device (3) and a buffer and energy storage device (4), wherein, one end of a movable core push rod (36) of the permanent magnetic position-keeping auxiliary drive device (3) is connected with a tube-type push rod of the buffer and energy storagedevice (4); the super-fast operating mechanism is characterized in that the other end of the movable core push rod (36) of the permanent magnetic position-keeping auxiliary drive device (3) is connected with an electromagnetic eddy current repulsion main drive device (2) which is used for providing initial operating force for operating the switch; the permanent magnetic position-keeping auxiliarydrive device is used for providing stable and reliable power when a switch contact moves to the position of 5mm and keeping the switch contact in position when the movement of the switch is over; thebuffer and energy storage device is used for reducing the impact of the operating mechanism to the shell of the mechanism and the switch contact during the operating process and storing the energy inthe form of spring energy for next switching operation .

Description

technical field [0001] The invention belongs to switch spare parts, and is a driving device for switching a switch, in particular to an ultra-fast operating mechanism for a high-voltage switch. Background technique [0002] With the improvement of the comprehensive automation level of substations and the acceleration of the green grid construction process, issues such as improving the safety and reliability of the grid, strengthening the protection of electrical equipment in the grid, improving the power quality of the grid, and reducing harmonic pollution have become more and more popular among the public. focus on. And the present switch accessories-the operating machine constitutes the bottleneck to solve the above problems. [0003] The operating speed of the first operating mechanism cannot meet the requirement of an ultra-fast switch. At present, the basic requirement for ultra-fast switching is to ensure that the starting time of the mechanism is less than 5ms, and ...
