The underframe between the in-out line insulators is provided with a linkage shaft, wherein one end of the linkage shaft is articulated with the underframe and the other end is provided with a handle; the linkage shaft is fixed with a connecting plate, and the other end of the connecting plate is respectively articulated with an insulating tension rod; the other end of the insulating tension rod is articulated between the contact blades; the linkage shaft is provided with an elbow-type spring pedestal; one end of a power assisting selflocking device is fixed on the pedestal of the underframe and other end is fixed on the elbow-type spring pedestal of the linkage shaft. The utility model is capable of separating or switching on the triphase by one time operation; and the utility model has the advantages of simple operation, time and labor saving, high safety, simple structure, high reliability and low cost.
Description
One, technical field
The utility model relates to the electric switch technical field, relates in particular to the outdoor three-phase isolation switch of 10kv.
Two, background technology
In the power transmission and transforming equipment of electric power system, isolating switch is the visual plant of realizing dividing, close conversion line and guaranteeing interruption maintenance safety, the isolating switch that on the power transmission and transformation line of 10kv voltage, uses at present, and three-phase does not link; Therefore can only one when divide-shut brake one disconnect mutually or close mutually, the inconvenience that operates, and also the operating time is long more, and danger is big more, and the distance of threephase switch is very little, operates also inconvenience.
Three, summary of the invention
The purpose of this utility model solves the above-mentioned problems in the prior art exactly, provides a kind of simple in structure, can one-time action realizes three-phase separating brake or combined floodgate, and the high 10kv open air three of the reliability isolating switch that links.
For finishing above-mentioned purpose of the present utility model, technical solution of the present utility model is: a kind of 10kv open air three isolating switch that links, a underframe is arranged, and fix two rows, 3 insulators of every row on the underframe, one row is the inlet wire insulator, and another row is the outlet insulator; On the line insulator, terminal block is housed respectively every, terminal block connects respectively into and out of line, be provided with a contact knife every into and out of between the line insulator, this contact knife one end is hinged with the electric conductor that advances or outlet insulator top is fixing, and the other end is connected with the mobilizable contact of electric conductor that goes out or inlet wire insulator top is fixing; Described electric conductor and terminal block fix; One universal driving shaft is being installed on the underframe between the line insulator, and universal driving shaft one end is hinged on the underframe, and the other end is mounted with handle after passing through the other end of underframe; Universal driving shaft has connecting plate in every fixed-site between the line insulator, the other end of connecting plate is hinged on the insulated tension pole respectively, the other end of insulated tension pole is hinged on the centre of each contact knife, universal driving shaft also is fixed with an elbow type spring pedestal vertical with connecting plate at an end that is hinged on underframe, power-assisted self-locking spring one end is fixed on the base on the underframe, and the other end is fixed on the elbow type spring pedestal of universal driving shaft.
Because the utility model has adopted such scheme, the underframe of isolating switch makes progress during use, and contact knife is downward.When stirring handle counterclockwise or clockwise, universal driving shaft rotates, connecting plate fixed thereon rotates, with the insulated tension pole top down, the elbow of universal driving shaft drive simultaneously type spring pedestal rotatablely moves, compression power-assisted self-locking spring, make it accumulation of energy, after universal driving shaft turned an angle, the power-assisted self-locking spring was in maximum energy accumulating state, continue to stir handle this moment, elbow type spring pedestal fixed thereon rotates, and causes the power-assisted self-locking spring to release energy, and quickens the universal driving shaft rotation, contact knife is moved down fast push away electric conductor, realize separating brake.When needs close a floodgate, stir handle clockwise or counterclockwise, universal driving shaft rotates, and connecting plate fixed thereon rotates, and insulated tension pole is retracted, the elbow of universal driving shaft drive simultaneously type spring pedestal rotatablely moves, compression power-assisted self-locking spring makes it accumulation of energy, after universal driving shaft turns an angle, the power-assisted self-locking spring is in maximum energy accumulating state, continue to stir handle this moment, elbow type spring pedestal fixed thereon rotates, and causes the power-assisted self-locking spring to release energy, the rotation of acceleration universal driving shaft, contact knife is retracted rapidly fast contact with electric conductor, the back power-assisted self-locking spring that puts in place is in free state, and as long as contact knife and electric conductor have the meaning of unclamping, the power-assisted self-locking spring can produce pressure at once, make it to take place compression, so universal driving shaft is difficult to rotation, make contact knife tightly clamping on electric conductor, can not move down, play auxiliary self-locking action.In a word, the utility model can one-time action be realized the separating brake or the combined floodgate of three-phase, and is simple to operate, time saving and energy saving, safe.And simple in structure, reliability is high, cost is low.
Four, description of drawings
Below in conjunction with accompanying drawing the utility model is described further:
Structural representation when Fig. 1 opens a sluice gate for the utility model.
Five, embodiment
As shown in Figure 1, a kind of 10kv open air three isolating switch that links has a underframe 1, fixes two rows on the underframe 1,3 insulators of every row, 3, one rows are the inlet wire insulator, and another row is the outlet insulator.On line insulator 3 terminal block 2 is housed respectively every, terminal block 2 connects into and out of line respectively.Into and out of being provided with a contact knife 5 between the line insulator, these contact knife 5 one ends are connected by bearing pin 14 with the electric conductor 15 that advances or outlet insulator 3 tops are fixing every, and the other end is connected with the electric conductor 7 mobilizable contacts that go out or inlet wire insulator 3 tops are fixed.Described electric conductor 15,7 and terminal block 2 fix.One universal driving shaft 10 is being installed on the underframe 1 between the line insulator 3, and universal driving shaft 10 1 ends are hinged on the underframe 1, after the other end passes through the other end of underframe 1, are mounted with handle 11.Universal driving shaft 10 is welded with connecting plate 9 in every position between the line insulator, and the other end of connecting plate 9 inserts in the groove of insulated tension pole 4, and is fixed on the insulated tension pole 4 by bearing pin 8.The other end of insulated tension pole 4 inserts between two of contact knife 5, and is fixed on each contact knife 5 by bearing pin 6.The end that universal driving shaft 10 is hinged on underframe 1 also is fixed with an elbow type spring pedestal 12 vertical with connecting plate 9, and power-assisted self-locking spring 13 1 ends are fixed on the base on the underframe 1, and the other end is fixed on the elbow type spring pedestal 12 of universal driving shaft 10.
