Abstract
The utility model discloses a ring main unit fuse/ground integration type operating mechanism. An upper crank arm is mounted on a main shaft of the operating mechanism and connected with a connection rod, a lower crank arm and a rotation handle are respectively fixed on the lower end of the connection rod; the lower crank is connected with a main loop trigger, the rotation handle is connected with a grounding locking device, and the grounding locking device is connected with a grounding trigger. A groove is arranged on the grounding locking device. Aiming at the existing problems, the ring main unit fuse/ground integration type operating mechanism is provided. A spring support column is used to accomplish the opening and closing action of a main loop and the grounding, the locking device is changed into a linkage structure, and when a main loop switch is closed, a ground brake is ensured to be at the open state.
Description
Technical field
The utility model belongs to the ring main unit technical field, relates in particular to the one-piece type operating mechanism of a kind of ring main unit fuse/ground connection.
Background technology
Ring main unit is a kind of electric equipment that is contained in high voltage switchgear in the metal enclosed body or manufactures assembly unit compartment ring network power supply unit, on-load switch and fuse are adopted in its core, have simple in structure, volume is little, price is low, can improve power supply quality and advantages such as performance and power supply safety.It is widely used in electric power such as city and residential quarters, large public building, factory and enterprise for in the power distribution station and box-type substation at center.
Present employed ring main unit switch is the divide-shut brake action of finishing major loop and ground connection with two spring support columns respectively, and the ground connection locking device adopts is manual operation, the cost height, and complex operation, the misoperation probability is big.
The utility model content
The purpose of this utility model is to provide a kind of ring main unit fuse/ground connection one-piece type operating mechanism, being intended to solve present employed ring main unit switch is the divide-shut brake action of finishing major loop and ground connection with two spring support columns respectively, and the employing of ground connection locking device is manual operation, the cost height, complex operation, the problem that the misoperation probability is big.
The utility model is achieved in that the one-piece type operating mechanism of a kind of ring main unit fuse/ground connection, installs connecting lever on the main shaft of the one-piece type operating mechanism of described ring main unit fuse/ground connection; Last connecting lever links to each other with connecting rod, and the connecting rod lower end is fixing connecting lever and turning handle down respectively; Following connecting lever links to each other with the major loop sneek, and turning handle is connected with the ground connection locking device; The ground connection locking device links to each other with the ground connection sneek.
Further, arrangement of grooves on the described ground connection locking device.
At the problem of present existence, this programme has been invented the one-piece type operating mechanism of ring main unit fuse/ground connection.Adopt a spring support column to finish the divide-shut brake action of major loop and ground connection, and locking device changes linkage structure into, when guaranteeing that the major loop switch closes a floodgate, the ground connection lock is in gate-dividing state.
Description of drawings
Fig. 1 is the structural representation of the one-piece type operating mechanism of ring main unit fuse/ground connection that provides of the utility model;

Among the figure: 1, main shaft; 2, go up connecting lever; 3, connecting rod; 4, following connecting lever; 5, turning handle; 6, major loop sneek; 7, ground connection locking device; 8, groove; 9, ground connection sneek.
Embodiment
In order to make the purpose of this utility model, technical scheme and advantage clearer, below in conjunction with drawings and Examples, the utility model is further elaborated.Should be appreciated that specific embodiment described herein only in order to explaining the utility model, and be not used in restriction the utility model.
Fig. 1 shows the structure of the one-piece type operating mechanism of ring main unit fuse/ground connection that the utility model provides.For convenience of explanation, only show the part relevant with the utility model.
This device comprises: install connecting lever 2 on the main shaft 1; Last connecting lever 2 links to each other with connecting rod 3, and connecting rod 3 lower ends are fixing connecting lever 4 and turning handle 5 down respectively; Following connecting lever 4 links to each other with major loop sneek 6, and turning handle 5 is connected with ground connection locking device 7; Arrangement of grooves 8 on the ground connection locking device 7, and ground connection locking device 7 links to each other with ground connection sneek 9.
The beginning major loop is in gate-dividing state, contact of earth.Rotate by manual control main shaft 1, the last connecting lever 2 above the main shaft 1 upwards rotates, and last connecting lever 2 drivening rods 3 move upward; Connecting rod 3 drives the following connecting lever 4 and the turning handle 5 that connect below and clockwise rotates around axle together, thereby the major loop sneek 6 that links to each other with following connecting lever 4 is together clockwise rotated, the ground connection locking device 7 that links to each other with turning handle 5 simultaneously moves right, thereby driving ground connection sneek 9 clockwise rotates, major loop closes a floodgate, the ground connection separating brake.By the effect of ground connection locking device 7, make when major loop is in "on" position that the ground connection disconnecting link is lived by locking.
The one-piece type operating mechanism of ring main unit fuse/ground connection of this programme invention.Rotate by manual control main shaft 1, the last connecting lever 2 above the main shaft 1 upwards rotates, and last connecting lever 2 drivening rods 3 move upward; Connecting rod 3 drives the following connecting lever 4 and the turning handle 5 that connect below and clockwise rotates around axle together, thereby the major loop sneek 6 that links to each other with following connecting lever 4 is together clockwise rotated, the ground connection locking device 7 that links to each other with turning handle 5 simultaneously moves right, thereby driving ground connection sneek 9 clockwise rotates, major loop closes a floodgate, the ground connection separating brake.By the effect of ground connection locking device 7, make when major loop is in "on" position that the ground connection disconnecting link is lived by locking, avoid the ground connection disconnecting link that under the state that the major loop switch closes a floodgate, closes, thus the earth fault of causing.This device has reduced production cost, and is convenient for production, easy to operate, stopped misoperation.
The above only is preferred embodiment of the present utility model; not in order to limit the utility model; all any modifications of within spirit of the present utility model and principle, doing, be equal to and replace and improvement etc., all should be included within the protection range of the present utility model.
