Abstract
A switch apparatus having pyrotechnic actuator includes a itch body and the pyrotechnic actuator. The switch body includes a static contact part which is fixed and a movable contact part which is movable. The pyrotechnic actuator is an independent modular construction and is fixedly mounted on the switch body from the outside of the switch body. The pyrotechnic actuator can ignite gunpowder to generate an explosive impact force that pushes the movable contact part away from the static contact part according to the load condition of the switch body, so as to assist the switch apparatus to be quickly disconnected.
Claims13
A switch apparatus having a pyrotechnic actuator, comprising:
- a switch body;
- comprising a static contact part fixedly disposed and a movable contact part movably disposed;
- to perform a switch function;
- and
- a pyrotechnic actuator;
- being an independent modular construction, fixedly installed on the switch body from an outside of the switch body, wherein the pyrotechnic actuator is adapted to ignite gunpowder according to a load condition of the switch body to generate an explosive impact force that pushes the movable contact part away from the static contact part, so as to assist the switch apparatus to disconnect quickly.
A system, comprising:
- a switch apparatus having a pyrotechnic actuator, comprising:
- a switch body comprising a static contact part fixedly disposed and a movable contact part movably disposed to perform a switch function;
- and
- a pyrotechnic actuator having an independent modular construction, the pyrotechnic actuator being fixedly installed on the switch body from an outside of the switch body,
- wherein the pyrotechnic actuator is configured to ignite gunpowder according to a load condition of the switch body to perform a disconnection by generating an explosive impact force that pushes the movable contact part away from the static contact part.
