Abstract
Disclosed is a high-pressure rotating disconnecting-switch with three working positions, comprising an upper stationary contact (3), a lower stationary contact (14), and a movable contact (2) mounted on a rotation shaft (1) of the movable contact. The switch is characterized in that a controlling rod (6) and a ground rotation shaft (9) are further disposed, a lever (7) is fixed on the connecting rod, then the lever is hinged with a lever (16) mounted on the rotation shaft of the movable contact and a lever of the ground rotation shaft via a connection rod (15) and a connecting rod (8), and a ground blade (11) is fixed on the ground rotation shaft. The utility model has simple structure, small volume, light weight, and reliable chain locking mechanism. With only one controlling rod, the utility model reaches the functions of switch closing, switch opening and ground connection.
Description
Technical field
The utility model belongs to a kind of three station high voltage rotary isolation switch.
Background technology
The high voltage rotary isolation switch of domestic production at present mostly is two stations, promptly only establish combined floodgate, two positions of separating brake, so also need add the ground connection switch in addition when it is used in the high-tension switch cabinet supporting use, and in order to ensure personal safety, between the rotary isolation switch of the enterprising line operate of cabinet and two action bars of rotation earthed switch, also need to be provided with mechanical interlock mechanism, so just make the high-tension switch cabinet volume big, complex structure.
Summary of the invention
Problem to be solved in the utility model provide a kind of simple in structure, volume is little, the realizing of reliable operation closed a floodgate, three station rotary isolation switch of separating brake, three kinds of functions of ground connection.
The technical scheme that addresses the above problem is (referring to implementing illustration): the utility model comprises upper static contact (3), following fixed contact (14), be positioned at, be positioned on moving contact (2) in the moving contact rotating shaft (1) between the following fixed contact, it is characterized in that: also be provided with action bars (6) and a ground connection rotating shaft (9) parallel with moving contact rotating shaft (1), be fixed with connecting lever (7) on the action bars, connecting lever (7) respectively by with its hinged link rod (15) and link rod (8) and moving contact rotating shaft on connecting lever (16) be connected with connecting lever (10) hinge in the ground connection rotating shaft, be fixed with in the ground connection rotating shaft at moving contact (2) with last, following fixed contact gate-dividing state down can with the ground connection cutter (11) of following fixed contact (14) connection.
Operation principle of the present utility model is: see Fig. 2: on closing position, moving contact (2) will be gone up, following fixed contact (3), (14) connect, ground connection cutter place separates state, during separating brake, rotating operation bar (6), its connecting lever (7) is respectively by link rod (15), connecting lever (16) and link rod (8), connecting lever (10) drives moving contact rotating shaft (1) and ground connection rotating shaft (9) is rotated, moving contact rotates earlier with last with the moving contact rotating shaft, following fixed contact separately, ground connection cutter 12 rotates final and following fixed contact with the ground connection rotating shaft and connects, make down fixed contact (14) ground connection, this moment, moving contact remained on separating brake position (see figure 4); When being closed a floodgate by the separating brake position, the rotating operation bar drives moving contact to the motion of combined floodgate direction by linkage, and the ground connection cutter separates with following fixed contact earlier, reach certain distance after, moving contact moves to closing position, with upper and lower fixed contact connection.
The utility model is simple in structure, and volume is little, and is in light weight, and interlocking device is reliable, only can finish the operation of combined floodgate, separating brake, ground connection with an action bars, is contained in the high-tension switch cabinet, can make the high-voltage board designs simplification, and volume reduces.

Specific embodiments
Present embodiment moving contact rotating shaft 1, action bars 6, ground connection rotating shaft 9 is installed in parallel on the support 4, moving contact rotating shaft 1 and ground connection rotating shaft 9 lay respectively at action bars 6 both sides, being equipped with in the moving contact rotating shaft can be with the moving contact 2 of upper static contact 3 and 14 connections of following fixed contact, following fixed contact 14 is electrically connected with the grounding contact 12 of a side, the ground connection rotating shaft is provided with the ground connection cutter 11 that is nearly 90 degree angles with moving contact, also be provided with the grounding nut 17 that can be electrically connected with ground wire, be fixed with connecting lever 7 on the action bars 6, connecting lever lower end one side is by being connected with connecting lever 10 hinges of ground connection rotating shaft with the link rod 8 of its hinge, and opposite side is by being connected with connecting lever 16 hinges of moving contact rotating shaft 1 with the link rod 15 of its hinge.
Ground connection rotating shaft 9 is provided with spring and connects connecting lever 18, and ground spring 19 1 ends are fixed on the support 4 fast, and the other end is connected connecting lever 18 and connects with spring, make the ground connection rotating shaft be in bistable state under spring action.
In "on" position, moving contact 2 is connected upper static contact 3 and following fixed contact 14, the ground connection cutter 11 that is an angle with moving contact is in gate-dividing state, rotating operation bar 6, can drive moving contact rotating shaft 1 and ground connection rotating shaft 9 simultaneously by link mechanism and rotate, moving contact separates with upper and lower fixed contact earlier, when assigning to reliable insulation distance, ground connection cutter rapid grounding contact 12 with following fixed contact under the effect of quick ground spring 19 closes a floodgate, and makes down fixed contact ground connection.During combined floodgate, the rotating operation bar drives the ground connection rotating shaft and the moving contact rotating shaft is rotated, and the ground connection cutter breaks away from earlier the grounding contact 12 of fixed contact down, when reaching reliable insulation distance, under the ground spring effect moving contact is closed a floodgate fast with upper and lower fixed contact fast.
