Spirng Operation Mechanism LBS

CT Type spring operating mechanism was available for FLRN36-12D/T100-31.5 and FLN36-12D/630-20 indoor high voltage SF6 load switch, rated voltage 12kV indoor switch Auxiliary equipment, this series of mechanisms is made by the principle of compression spring over-release, its work position is three positions: closing, opening and grounding. It has a moderate size and is easy to install and use and has the characteristics of strong applicability. It has the function of fuse breaking and opening and disassembly tripping Coil.

The mechanism complies with GB3804-1990 《3~63kV AC high voltage load switch》,

GB16926-1997 《AC high voltage load switch - fuse combination electric appliance》Technical requirements.

What are the circuit breaker operating mechanisms?

1. Transmission organization: The transmission structure of the circuit breaker is generally four-bar linkage. According to different operation methods, the transmission organization can be divided into five types: handle transmission organization (manual), electromagnet transmission organization, motor transmission organization, pneumatic and hydraulic transmission organization. . In the meantime, the handle transmission structure is generally used for small-capacity circuit breakers; the electromagnet transmission organization and the motor transmission organization are mostly used for large-capacity circuit breakers for long-distance operation. 

According to the different closing methods, the transmission organization is divided into two types: energy storage closure and non-storage energy closure. In the meantime, the energy storage closure is to tighten the spring in advance, and then use the energy released by the spring to close the contact, and the closing speed and force obtained by the spring are independent of the size and speed of the force applied by the operator, ensuring stable closure. Force and closing speed; the closing speed and force obtained by non-energy storage closing transmission tissue, depending on the size and speed of the applied force, requires operation by a skilled operator.
