The high-voltage switchgear now generally adopts a spring operating mechanism and uses a high-voltage switch energy storage motor; when the circuit breaker in the high-voltage switchgear is closed or opened, the spring of the high-voltage switch energy storage motor releases energy and relaxes; when the spring relaxes to a certain degree To the extent that the positional contact of the control spring activates the high-voltage switch energy storage motor to store energy for the slack spring;
When the spring is compressed to a certain extent by the high voltage switch energy storage motor, the position contact of the control spring will stop the energy storage motor, stop the spring energy storage; reserve energy for the next switch of the switch. Therefore, in the high-voltage cabinet to which the spring energy storage operating mechanism is applied, it is necessary to store energy before closing before closing.
The energy storage mechanism is driven by a high-voltage switch energy storage motor to drive the gear mechanism to lengthen the spring. There are two methods of operation: electric and manual. Failure to store energy manually should be a mechanical failure of the mechanism. Manual energy storage, but electric energy storage is an electrical fault. Mechanical wear that occurs shortly after use is generally not a mechanical failure.
