Structure of product GW5 Disconnect switch consists of 3 single- pole, operating device and transfer section. Each single-pole is of a "V" structure which consists of bottom ,bearing seat, support insulator, connector, left & right contactor , earthing static contactor and earth knife switch.For this disconnect switch, the main knife can not only match CS17 series manual operating device, but also match CJ6G electric operating device. Earth knife matches CS17 series manual operating device . CS17 series manual operating device is equipped with F9 type auxiliary switch or vacuum auxiliary switch .When manual operating device attach electromagnetic lock, valid electric chain lock will be effected among disconnect switch, earth switch and circuit breaker to avoid mistake operating.4. Operating principle 4.1 operating principle for main knife switch Operating device of GW5 disconnect switch is connected to the oscillating arm through a vertical transfer lever and connector. Synchronous action of 3-pole can be effected through oscillating arm pulling the 3 separate pole.When the device acting, a support insulator is driven to rotate ;another support insulator is driven to rotate through a lever in bottom shelf (leftright contactors are separately fixed on 2 support insulators). Then action of switchin and switchoff of the 2contactors can be effected. 4.2 Operating principle of earth knife switch The 3-pole earth knife are connected by 3-pole transfer lever. Principle axle of operating device is connected to the 3-pole transfer lever through vertical transfer lever ,contactor and a set of space 4-links bar. Switch in and switch off of earth knife can be effected through vertical transfer lever and space 4-links bar when the device acting. 4.3 Auxiliary switch in operating device is connected to principle axle of device. When action (switch in or switch off), related contact will be opened or closed, Then give signals of switch in or switch off.4.4 Mechanical lock-out of main earth knives When the main knife and the earth knife both attach manual operating device, Lock-out between disconnect switch and earth switch is effected through interlock board of the device. When closed the disconnect knife, the earth knife can not be closed ;When earth knife is closed, don't close the disconnect switch. 5.
