A high-voltage surge arrester with high seismic resistance
ActiveCN121075772BResistor terminals/electrodesResistor mounting/supportingClassical mechanicsSeismic resistance
This invention discloses a high-vibration-resistant high-voltage surge arrester, specifically relating to the field of surge arrester technology. It includes a surge arrester body, a buffer assembly, and an adjustment assembly. Through the buffer assembly, this invention can release the blockage of the vent hole when the surge arrester body experiences severe, large-amplitude vibrations. It can adjust the buffer rigidity, allowing the first piston to continue moving downwards for buffering, thus improving the buffering effect. Furthermore, as the first piston moves to the bottom of the first chamber, it gradually blocks the connecting hole, acting as a throttling device, gradually reducing the oil output within the connecting hole. This further slows the descent speed of the first piston, thus providing multi-stage buffering. This prevents buffer failure and impacts under large-amplitude vibrations, further improving the buffering effect and extending the service life of the surge arrester.

A voltage limiting overvoltage protection assembly with a recoverable electromagnetic drive trip mechanism
ActiveCN116864351B
The application discloses a voltage-limited overvoltage protection component with a recoverable electromagnetic drive tripping mechanism, which is composed of a voltage-limited overvoltage protector and an electromagnetic drive tripping mechanism. In a normal state, the normally closed contact of the electromagnetic drive tripping mechanism is in a closed state, which does not affect the normal working state of the voltage-limited overvoltage protector and the protection state under a normal intensity overvoltage. When an overvoltage occurs, a pulse current flowing through the voltage-limited pressure-sensitive resistor induces a current in the upper metal disc of the electromagnetic drive tripping mechanism, which is opposite to the direction of the spiral conductor coil of the lower electromagnetic drive disc, so that the upper metal disc of the lower electromagnetic drive mechanism induces an electromagnetic repulsive force with the lower electromagnetic drive disc, thereby causing the normally closed contact of the electromagnetic drive tripping mechanism to break, effectively inhibiting the continuous effect of a subsequent power frequency or direct current arc on the voltage-limited protector, prolonging the service life of the voltage-limited overvoltage protection component, and effectively realizing the safe use coefficient and prolonging the service life of the voltage-limited overvoltage protection component.
