Contact.
The utility model good effect is as follows: the spring of the utility model can make isolation knife and insulated pull rod move to mechanism
When crossing dead-centre position, movement rapidly, realizes the splitting or integrating lock snap action of disconnecting switch, ensure that people under spring force
Body safety；Spring can be such that when the splitting or integrating gate position of disconnecting switch holding mechanism stablizes motionless simultaneously, ensure that the fortune of disconnecting switch
Row stability.When disconnecting switch is closed a floodgate, isolation knife is separated with grounding contact, and is kept in contact with static contact, and route is connected, can
To carry the rated current under normal running (operation) conditions and the fault current in the abnormal operating conditions lower stipulated time；When keeping apart
When closing separating brake, isolation knife is separated with static contact, and is kept in contact with grounding contact, and route disconnects, and forms enough insulation distances
Meet electric clearance requirement, there is apparent visible cut-off point, on/off switch state is intuitive, while leading-out terminal reliable ground, protects
The personal safety as well as the property safety of High-Voltage Electrical Appliances and device during maintenance is demonstrate,proved.The utility model is structurally reasonable, easy to operate, safe can
It leans on, integral installation mode, inlet-outlet line mode are versatile and flexible, such as can be switched number of poles with left and right sides dress, formal dress, bilateral inlet wire and be matched
It sets flexibly, standardization level is high, and component universality is good.
