The transmission device of the outdoor high-voltage earthing switch can preferably ensure contact reliability of the moving contact and the fixed contact of the earthing switch, and ensure the safety of equipment and overhauling staff.
Description
Technical field:
The utility model relates to a kind of transmission device, especially a kind of outdoor high-voltage earthed switch transmission device.
Background technology:
Earthed switch that is assembled into one with outdoor high-voltage isolating switch or the independent earthed switch that uses, ground connection cutter forms of motion adopts ground connection cutter moving contact under the driving of ground connection rotating shaft, rotate, remake the two-step structure of inserting the ground connection fixed contact behind the rectilinear motion earlier, have in electric power, wind-force and external force and do the time spent, the high characteristics of the dynamic and static contact contact reliability of earthed switch help assurance equipment and maintainer's safety.In the prior art, the most employing of the ground connection cutter forms of motion of two-step structure adds the balance pull-spring balance and lives the ground connection cutter on the ground connection knife support, but in the earthed switch that adopts the lever operating mechanism, because releasing of extension spring can and act on the operating grip when separating brake, and the equipment operator is constituted certain potential safety hazard.
The utility model content:
The purpose of this utility model provides a kind of outdoor high-voltage earthed switch transmission device, and it can overcome the deficiency that there is potential safety hazard in existing apparatus.
The purpose of this utility model is achieved through the following technical solutions:
A kind of outdoor high-voltage earthed switch transmission device, by the ground connection knife support, the ground connection cutter, the ground connection fixed contact is formed, it is characterized in that: on the ground connection knife support, two clamping plate are fixedlyed connected with the ground connection cutter down, last, one initiatively connecting lever and rotating shaft is set between two clamping plate down, between active connecting lever and rotating shaft, be hinged with a driven connecting lever, when earthed switch closes a floodgate, driving the ground connection cutter by the active connecting lever rotates, when ground connection cutter moving contact when baffle plate on the ground connection fixed contact contacts, driven connecting lever promotes the ground connection knife support and makes rectilinear motion upwards, make ground connection cutter moving contact insert the ground connection fixed contact, realize closing operation; During separating brake and the combined floodgate reverse movement.
Upper and lower two clamping plate of described ground connection knife support respectively have a square hole, and initiatively connecting lever is loaded between the square hole of upper and lower two clamping plate.
Described active connecting lever and driven connecting lever are equipped with an angle [alpha] at sub-gate position.
The outdoor high-voltage earthed switch transmission device that the utility model provides can guarantee contact reliability, assurance equipment and maintainer's safety of the dynamic and static contact of earthed switch preferably.

Embodiment:
Describe below in conjunction with drawings and Examples.
As Fig. 1～5, the utility model is made up of ground connection knife support, ground connection cutter, ground connection fixed contact, the ground connection knife support is made of active connecting lever 1, driven connecting lever 2, train wheel bridge 6, lower plate 11, support bar 5, pivot pin 8 and rotating shaft 9, and the ground connection cutter is made of ground connection knife bar 3, ground connection cutter moving contact 4 and screw 10.Upper and lower two clamping plate of ground connection knife support and ground connection cutter be for fixedlying connected, and initiatively connecting lever and ground connection swivel axle 7 are for fixedlying connected.On upper and lower two clamping plate of ground connection knife support, respectively have a square hole, the active connecting lever 1 that the end is shaped on the step cover is loaded between the square hole of two clamping plate, and can in square hole, rotate and slide along square hole, between upper and lower two clamping plate one rotating shaft is set, driven connecting lever is articulated and connected with rotating shaft, active connecting lever respectively, is provided with a baffle plate on the ground connection fixed contact.
The ground connection fixed contact is made up of ground connection stationary contact headstock 12, pressing plate 14, spring 15, contact 16 and baffle plate 18, pressing plate and contact are fixedly connected on the ground connection stationary contact headstock 12 with bridge screw 13, be provided with spring 15 between pressing plate and contact, baffle plate is fixedly connected on the ground connection stationary contact headstock with baffle plate screw 17.
The transmission mechanism that adopts above-mentioned active connecting lever and driven connecting lever to constitute, when earthed switch closes a floodgate, ground connection swivel axle rotates under the driving of mechanism, because initiatively connecting lever and ground connection swivel axle are for fixedlying connected, initiatively connecting lever also rotates simultaneously, and then drive driven connecting lever and make whole ground connection knife support solderless wrapped connection ground swivel axis rotation, simultaneously since upper and lower two clamping plate of ground connection knife support and ground connection cutter for fixedlying connected, the ground connection cutter too solderless wrapped connection the swivel axis rotation.When ground connection cutter moving contact and baffle plate on the ground connection fixed contact contact and limit when rotating, the ground connection cutter can not rotate again, but being passed to driven connecting lever, rotatablely moving of active connecting lever rotate around the shaft, because it is main, between driven connecting lever, reach driven connecting lever and ground connection knife support for being articulated and connected, and an angle [alpha] arranged, main, the distance of the pivot of driven connecting lever will increase, simultaneously, because initiatively connecting lever is contained in, down between the square hole of two clamping plate, and can in square hole, rotate and slide along square hole, main, the pivot of driven connecting lever apart from augmenting portion, promote of line do upwards the straight-line displacement of ground connection knife support with being converted to driven connecting lever along active connecting lever pivot and driven connecting lever pivot, be that ground connection cutter moving contact is made straight-line displacement insertion ground connection fixed contact upwards, stop operating until mechanism, realize closing operation.During separating brake and the combined floodgate reverse movement.This transmission device can guarantee the contact reliability of the dynamic and static contact of earthed switch preferably, assurance equipment and maintainer's safety.
