Specific embodiment：
In order to clarify the technical characteristics of the invention, below by specific embodiment, and its attached drawing is combined, to this reality
It is described in detail with novel.
As shown in Figs 1-4, a kind of substation outdoor energy-saving disconnecting switch, including shelving pedestal 1,1 one end of pedestal are equipped with
Left frame 2 is equipped with the first contact 4 by insulating materials 3 on left frame 2, and 1 other end of pedestal is movably equipped with right rack 5, right machine
The second contact 6 being equipped with the first contact 4, separate second contact 6 of right rack 5 are equipped with by insulating materials 3 on frame 5
It is successively arranged separator 7, retarder 8 and motor 9 on the pedestal 1 of side, is also movably equipped on pedestal 1 parallel with pedestal 1
Screw rod 10, right 5 bottom of rack be equipped with screw hole corresponding with screw rod 10, screw rod 10 pass through right 5 bottom of rack screw hole with separate
7 one end of device is connected, and 7 other end of separator is connected by shaft 11 with the output shaft of retarder 8, the input shaft of retarder 8
It is connected with the output shaft of motor 9.The shelving of pedestal 1 designs, and move right support and the second contact 6 can using gravity oliquely downward
It is dynamic, effectively save resource；Screw rod 10 can rotate above pedestal 1, and when right support uplink, motor 9 drives screw rod 10 to rotate, spiral shell
Right support on bar 10 moves upwards.
The separator 7 includes the subcard disk 12 being connected with screw rod 10 and the master card disk 13 being connected with shaft 11, master card
Disk 13 is arranged with sleeve 14 in the shaft 11 far from 12 side of subcard disk, sleeve 14 is equipped with knob 15, is additionally provided in shaft 11
Bulge loop 16 is arranged with spring 17 in the shaft 11 between sleeve 14 and bulge loop 16.Sleeve 14 can drive master card disk 13 along shaft 11
Direction is mobile, while can rotate with shaft 11；When unclamping knob 15, subcard disk 12 engages with master card disk 13, from motor 9
Power passes to master card disk 13 by shaft 11, and master card disk 13 drives subcard disk 12 to rotate, and then screw rod 10 is driven to rotate, and makes the right side
Rack 5 moves obliquely upward along screw rod 10；When pulling knob 15 to 9 direction of motor, subcard disk 12 is separated with master card disk 13, right
Rack 5 is had the trend moved downward by gravity, and for subcard disk 12 without the obstruction of master card disk 13, screw rod 10 can be free
Rotation, the trend that right support moves downward will push the rotation of screw rod 10, and screw rod 10, which rotates, will drive right rack 5 to obliquely downward
Fang Yidong does not need electric energy or manpower, effectively saves resource, improves work efficiency.
First contact 4 is equipped with photo resistance 18, and photo resistance 18 is connected with 9 control circuit of motor.
9 control circuit of motor includes the power supply being sequentially connected in series, first switch 19, second switch 20 and motor 9,
Second switch 20 is also connected by photo resistance 18 with motor 9 simultaneously.When second switch 20 and No. 1 port closure, motor 9
Operation is just related to photo resistance 18, if there is light to be radiated in photo resistance 18,18 resistance value very little of photo resistance, motor 9 can be just
Often operation；If unglazed be radiated in photo resistance 18,18 resistance value of photo resistance is very big, is equivalent to open circuit, and motor 9 then can not be normal
Operation.When second switch 20 and No. 2 port closure, the presence or absence of illumination, will not influence the normal fortune of motor 9 in photo resistance 18
Row.
First contact 4 is static contact, and second contact 6 is Mume flower contact.
The insulating materials 3 includes epoxy resin insulator.
In progress in use, being closed first switch 19 first, and second switch 20 and No. 1 port is closed, it is photosensitive at this time
Resistance 18 has light irradiation, the resistance value very little of photo resistance 18, and motor 9 can operate normally, and motor 9 delivers power to retarder
8, the output shaft of retarder 8 is connected with the shaft 11 of separator 7, in the case where not pulling knob 15, subcard disk 12 and mother
Chuck 13 engages, and the output shaft rotation of retarder 8 drives the shaft 11 of separator 7 to rotate, and then screw rod 10 is driven to rotate, and makes
Right rack 5 moves obliquely upward along screw rod 10, and the second contact 6 moves closer to the first contact 4, until abutted with the first contact 4, when
After second contact 6 is abutted with the first contact 4, the second contact 6 is the photo resistance 18 covered on the first contact 4, photo resistance
Without illumination on 18, resistance value increases, and circuit is made to be equivalent to disconnection, and motor 9 is i.e. out of service, completes substation's use at this time
The closure of outdoor disconnector.
When separating substation's outdoor disconnector, a kind of situation is to pull the knob 15 on separator 7, subcard
Disk 12 is separated with master card disk 13, and right rack 5 is had the trend moved downward by gravity, and subcard disk 12 is without master card disk 13
Obstruction, screw rod 10 can be freely rotated, and the trend that right support moves downward will push the rotation of screw rod 10, and screw rod 10 rotates
It will drive right rack 5 oliquely downward to move, until completing substation at this time with outdoor isolation before reaching separator 7
The separation of switch.Another situation is that if when the first contact 4 and the second contact 6 cannot lean on Gravity Separation completely, by second switch
20 and No. 2 port closures, start motor 9, and invert motor 9, and start motor 9 at this time is not influenced by photo resistance 18, and one
The right beginning of rack 5 of denier oliquely downward moves, and can pull the knob 15 on separator 7, disconnect first switch 19, close motor
9, it moves right support oliquely downward by gravity, repeats the first situation, complete the separation of substation's outdoor disconnector.
Above-mentioned specific embodiment cannot function as the limitation to scope of protection of the utility model, for the skill of the art
For art personnel, any alternate modification or transformation made to the utility model embodiment all fall within the guarantor of the utility model
It protects in range.
Place is not described in detail for the utility model, is the well-known technique of those skilled in the art of the present technique.
