Description

A kind of isolating-switch locking operating mechanism
Technical field
The utility model relates to the lock operation mechanism that a kind of electrical switchgear is used.
Background technology
The isolating-switch locking operating mechanism is disconnecting switch operation and earthed switch, and can satisfy " the anti-mutually interlocking " requirement between interior each components and parts of switch cubicle and the front and back door.Isolating-switch locking operating mechanism commonly used as shown in Figure 1 and Figure 2, last isolating switch 5, following isolating switch 4 and last earthed switch 6 are located in the cabinet 1, the panel of cabinet 1 is provided with three disks 1, disk 1 rotation that action bars 3 moves up and down and drives operating mechanism, disk 1 are rotated by link rod and are made isolating switch or earthed switch connecting lever drive isolating switch or earthed switch close the branch operation; Isolating switch 5 in the operation, down when isolating switch 4 and last earthed switch 6, according to shareholder's order, successively action bars 3 is put into the handle hole of disk 1, disk 1 rotation that drives operating mechanism that moves up and down realizes separating brake and combined floodgate.The isolating-switch locking operating mechanism major defect of this structure has: operate cumbersome, the operation sequence disunity, the thing that misoperation often occurs takes place; In operation isolating switch 5, down isolating switch 4 or on during earthed switch 6, operating operation bar 3 will be in the conversion between the handle hole of corresponding disk 1; Will be when operation according to different scheme of electric power operations, operating sequence is unfixing; Isolate when Installation and Debugging and turn the difficult adjustment of the angle of keeping away angle and operating mechanism, angle cooperates bad meeting to cause the operation effort and closes branch to keep apart the pass not in place.
The utility model content
Technical problem to be solved in the utility model is to overcome the prior art defective, provides a kind of easy to operate, need not memory operation order, simple and reasonable, anti-error performance is good, the reliable isolating-switch locking operating mechanism of handling safety.
Technical solution adopted in the utility model is: a kind of isolating-switch locking operating mechanism comprises support, be rotatably mounted with main shaft on the support, it is characterized in that above-mentioned main shaft secured in parallel is equipped with countershaft, be installed with three cams on the main shaft, cam is provided with dials bar, three corresponding on countershaft cam position places are set with three connecting levers rotationally, and three connecting levers connect corresponding operating side respectively, and connecting lever is provided with and the corresponding chute that bar cooperates of dialling.In use, the position and the angle that are installed with three cams are determined according to the position, operating side of the last isolating switch of correspondence, last isolating switch and earthed switch, the orientation of chute and length can guarantee that the bar of dialling that enters the chute notch breaks away from three operating sides that connecting lever connects corresponding last isolating switch respectively, goes up isolating switch and earthed switch again from this notch after cam turns over certain angle.
Operation principle is described: main shaft clockwise rotates the cam that drives on main shaft and rotates, when forwarding certain angle to, group bar of first cam enters the chute on the connecting lever, drives corresponding connecting lever, the operating side that interlock is corresponding, cam breaks away from from this notch again after turning over certain angle then; The corresponding operating side of the same principle interlock of second cam; The corresponding operating side of the same principle interlock of the 3rd cam realizes sending.Usually send the order of electricity operation to go up earthed switch for dividing earlier, isolation is closed down in the isolation of closing again again.During spindle axis counterclockwise rotation, realize the operation that has a power failure, divide earlier down and isolate, divide again to go up and isolate the ground connection of closing again.
During concrete enforcement, the end of main shaft is connected with operating grip, and during the operating grip rotation, the cam that main shaft is rotated drive on main shaft rotates.
The utility model operating mechanism is when operation upper and lower isolating switch or earthed switch, and operating grip does not need to change the handle hole position, and the anglec of rotation by main shaft realizes operation; Will be when operation according to different scheme of electric power operations, operating sequence is identical; As long as the angle of operating mechanism is constant suitable the isolating switch angle adjustment when Installation and Debugging, and anti-operating mechanism can be connected just by the mistake link rod with isolating switch, but bimanualness is laborsaving; Operation sequence is simple, is convenient to grasp.
The beneficial effects of the utility model are: because only needing control by the rotation of main shaft, the utility model send electricity and the operation that has a power failure, need not the memory operation order, and simple and reasonable, anti-error performance is good, handling safety is reliable.
The utility model is described in further detail below in conjunction with drawings and Examples:
