Embodiment
Below in conjunction with accompanying drawing the utility model is done explanation clearly and completely:
See also Fig. 1 and Fig. 2: present embodiment three-station operating mechanism is applicable to the switchgear of the electric pressure that 126KV is above.This three-station operating mechanism comprises: reducing motor 1, drive disk assembly 2, output shaft 3 and frame 5.Described reducing motor 1 is the motor of inner band gearbox.Described reducing motor 1 links to each other with output shaft 3 by drive disk assembly 2, and promptly described reducing motor 1 drives output shaft 3 through drive disk assembly 2 and rotates, and makes the position of three regulations of output shaft 3 arrival, i.e. combined floodgate, separating brake, these three stations of ground connection.The difference of present embodiment and existing three-station operating mechanism is: the spring 4 that discharges potential energy when energy storage when described output shaft 3 is provided with a combined floodgate, separating brake.
Shown in Fig. 4-6, described output shaft 3 is arranged in the hold-down support 7.The upper end of described spring is fixed on the described frame, and the lower end links to each other with described output shaft 3 by a connecting lever.Concrete structure is as follows: the lower end of described spring 4 is hinged on an end of described connecting lever 6 by a connecting plate.The other end of described connecting lever 6 is provided with a hole wall and has the hole 61 of circular arc " recessed " groove 611 and be socketed on the described output shaft 3.The outer surface of described output shaft 3 is provided with circular arc " protruding " piece 31 that cooperates with circular arc " recessed " groove 611 of described connecting lever 6, and the arc length of circular arc " recessed " groove 611 is longer than the arc length of circular arc " protruding " piece 31, and described output shaft 3 can rotate relative to connecting lever 6.Can also be provided with a locking mechanism 8 on the described output shaft 3, in order to output shaft 3 is locked in required station position.Described connecting lever 6 is set in the described bearing 7 with that end that output shaft 3 joins, and its other end stretches out from the opening 71 of bearing 7.
