Embodiment
Below, based on illustrated embodiment, solenoid operated opening and closing device of the present invention is described.
[embodiment 1]
The embodiment 1 of solenoid operated opening and closing device of the present invention is represented in Fig. 1 and Fig. 2.As shown in Figure 1, the solenoid operated opening and closing device of the present embodiment comprises substantially: the linkage portion 3 of the main circuit opening/closing portion 1 on right side, the electromagnetic operating device 2 in left side and downside.
Main circuit opening/closing portion 1 equally spaced configures three-phase part on diagram depth direction, is fixed on shutter fixed head 4.The vacuum valve with not shown contact separation pair of contact is freely provided with at main circuit opening/closing portion 1, be connected with fixation side main circuit conductor 5 in fixation side, be connected with drawer at movable side main circuit conductor 7 via flexible conductor 6 at drawer at movable side and Wiping mechanism (ワ イ プ Machine Agencies) be accommodated in inner operation insulating bar 8.The through shutter fixed head 4 in another side of operation insulating bar 8, is rotatably connected to one end of the main circuit opening and closing handle 9 in linkage portion 3.
In addition, electromagnetic operating device 2 is accommodated with in the inside of the housing 10 being formed as box-formed shape: produce the electromagnet 11 of actuating force, the not shown counter that electromagnet is carried out to excitatory capacitor, exports the control substrate of the control command of on-off action, open and-shut mode passed out to outside auxiliary contact, shows the display panel of open and-shut mode, counts on-off action number of times, the driving shaft 12 of electromagnet 11 is rotatably connected to the electromagnetic operating device handle 13 in linkage portion 3.
In addition, linkage portion 3 as shown in Figure 2, spline profile shaft 14 is embedded with main circuit opening and closing handle 9, electromagnetic operating device handle 13 and bearing parts 15 respectively, and the pipe 16 that each handle 9,13 and bearing parts 15 are used to fixed configurations separates, and the two ends of spline profile shaft 14 are configured in for the back-up ring 17 preventing pipe 16, each handle 9,13 comes off, be linked with operation insulating bar 8 at main circuit opening and closing handle 9, be linked with the driving shaft 12 of electromagnet 11 at electromagnetic operating device handle 13.
According to above-mentioned formation, solenoid operated opening and closing device can utilize the electromagnetic force produced by electromagnet 11, driving shaft 12 is driven in the vertical direction, this actuating force is via the electromagnetic operating device handle 13 in the linkage portion 3 being rotating shaft with spline profile shaft 14 and main circuit opening and closing handle 9, be delivered to main circuit opening/closing portion 1, the open state of double-throw contact thus and close state.
And, in the present embodiment, as shown in Figure 2, the length of the housing depth direction (arrow P) of spline profile shaft 14 is shorter than the length of the housing depth direction (arrow P) of framework framework bottom panel 18, and above-mentioned bearing parts 15 is configured in the position more in the inner part, end than spline profile shaft 14.Specifically, between the phase of main circuit opening/closing portion 1 being configured with three-phase (U phase, V phase, W phase), (between U phase with V phase and between V phase and W phase) is configured with bearing parts 15 respectively.
This bearing parts 15 as shown in FIG. 2 and 3, utilizes bolt etc. to fix at this 3 point of framework framework bottom panel 18, back side of shell plate 19 and shutter fixed head 4 ((I), (RO), (HA)).Namely, (I) for bearing parts 15 utilizes bolt etc. to be fixed on the structure of shutter fixed head 4 and back side of shell plate 19, (RO) for bearing parts 15 utilizes bolt etc. to be fixed on the structure of framework framework bottom panel 18, (HA) utilizes bolt etc. to be fixed on the structure of back side of shell plate 19 for bearing parts 15.
