Problems solved by technology
However, the switch of the invention has a relatively large acceleration and speed of the conduction element when opening and closing. Due to the limited rigidity of the plate-shaped actuator rod, it is prone to vibration and deformation under conditions of relatively high speed and acceleration, and it is easy to The impact or collision damages the fracture when the brake is opened, resulting in the failure of opening and closing, and the service life of the switch is short

The invention provides an ultra-high speed mechanical switch and a switch fracture thereof. The switch fracture comprises two conductive terminals and two differential board groups located between the conductive terminals, the differential board groups include one or more insulating plugboards which are mutually crisscross plugged, conductive elements capable of mutually staggering or arraying in a line to conduct the conductive terminals are arranged on the insulating plugboards of the differential board groups, insulating guide blocks are arranged at the positions of the front sides of the conductive terminals in the break-brake direction, and guide surfaces guiding the insulating plugboards to move in the break-brake direction and limiting the insulating plugboards to move vertically to the break-brake direction are arranged on the insulating guide blocks. When the switch fracture is in use, side faces of the insulating plugboards are jointly guided through the guide surfaces, vibration and deformation of the insulating plugboards vertically to the direction of the top sides are prevented, plugging stability and precision of the differential board groups during switching and closing movement of the insulating plugboards are improved, and service life is prolonged.
Description
technical field [0001] The invention relates to the field of high-voltage direct current transmission equipment, in particular to an ultra-high-speed mechanical switch and a switch fracture. Background technique [0002] The existing high-voltage switchgear has different parameters such as stroke, opening distance and overtravel according to the different voltage levels. Such a fracture structure determines that the opening time of the switch is mostly above 20ms, and on the basis of the existing structure If you want to increase the opening time, you can only increase the opening speed of the switch. The opening time required by ultra-high-speed mechanical switches is ≤2ms. Therefore, if the existing switch fracture structure is adopted, the opening time of the switch needs to be increased by more than 10 times, that is, the opening speed of the switch must be increased by at least 10 times. However, This speed increase is unrealistic. [0003] The invention patent with t...
