The invention relates to an emergency energy storing device for a spring mechanism of a sulfur hexafluoride circuit breaker. In the emergency energy storing device, a direct-current motor is connected with a power supply; a rotor of the direct-current motor is connected with one end of an input shaft of a speed reducer; the other end of the input shaft of the speed reducer is connected with a speed reducing gear; the speed reducing gear is connected with an output shaft of the speed reducer; and the output shaft of the speed reducer is provided with a groove. The emergency energy storing device has the advantages of reasonable design and simple structure, 12V or 24V direct current is used for supplying power to the direct-current motor, and a spring energy storing mechanism of a switch is driven to store energy through the speed reducer. The emergency energy storing of the spring energy storing mechanism of the switch is ensured under the condition of power cut, and the power supply reliability is enhanced. The emergency energy storing device can be widely applied to emergency energy storing of spring energy storing mechanisms of sulfur hexafluoride circuit breakers in power plants, power supply companies and transformer substations of industrial and mining enterprises, energy storing of the spring energy storing mechanisms of sulfur hexafluoride circuit breakers in emergency states is guaranteed, and normal operation of the switch is ensured.
Description
technical field [0001] The invention relates to an emergency energy storage device, in particular to an emergency energy storage device for a spring mechanism of a sulfur hexafluoride circuit breaker, which can be widely used in spring energy storage of sulfur hexafluoride circuit breakers in power plants, power supply companies, and substations of industrial and mining enterprises The emergency energy storage of the organization belongs to the field of intelligent power consumption and communication technology. Background technique [0002] At present, known spring energy storage mechanisms such as LW9 sulfur hexafluoride circuit breaker spring energy storage mechanisms rely on 220V AC motors for automatic energy storage, and their energy can only satisfy a cycle of "opening", "closing" and "opening". Once the substation fails to reclose due to a faulty switch protection trip, and there is no AC power supply in the substation during a total power failure, the spring energy ...
