Specific embodiments
In conjunction with the embodiments the charged extinguishing arc drainage procedure of the utility model bar is described in further detail:
Accompanying drawing has schematically shown the structure of the charged extinguishing arc drainage procedure of the utility model bar, comprises main body insulated tube 8, connection bolt 9, insulated connecting rod 4, separating brake extension spring 16, wire clamp head 1, crowbar switch and deciliter operating mechanism.Connection bolt 9 is fixed on the middle part of main body insulated tube 8, and crowbar switch is arranged on the termination (promptly anterior) of main body insulated tube 8, and deciliter operating mechanism is arranged on the rear portion of main body insulated tube 8.Wire clamp head 1, insulated connecting rod 4, crowbar switch and deciliter operating mechanism are that coaxial state is arranged on the main body insulated tube 8.Main body insulated tube 8 is the epoxy resin pipe that insulation property are good, mechanical strength is high, and insulated connecting rod 4 and separating brake extension spring 16 are arranged on the inside of main body insulated tube 8, and an end and the insulated connecting rod 4 of separating brake extension spring 16 are affixed, and the other end is fixed on the afterbody of main body insulated tube 8.Stretching of separating brake extension spring 16 drives insulated connecting rod 4 and moves in main body insulated tube 8.
Described handguard 10 is arranged on the medium position of main body insulated tube 8, is made hand slippage when preventing to operate by insulating material.
Crowbar switch comprises fixed contact 2, moving contact 3, explosion chamber 6, and moving contact 3 is fixed on the termination of insulated connecting rod 4, and is communicated with connection bolt 9 formations by connecting line 5, and the other end of insulated connecting rod 4 is equipped with contact over travel spring 21.Explosion chamber 6 is outer to be provided with outer cover 7, and the termination of outer cover 7 is provided with wire clamp head 1, and explosion chamber 6 is made by gas exhausted material, and outer cover 7 avoids producing outside arc light, offers heat radiation venthole (not drawing among the figure) on outer cover 7.
A deciliter operating mechanism that is arranged on main body insulated tube 8 rear portions comprises snap close 11, thrust piece 12, tooth bar 13, connecting bolt 14 and deciliter handgrip 15, snap close 11 and thrust key 12 are installed on the tooth bar 13, tooth bar 13 is fixed on the main body insulated tube 8, deciliter handgrip 15 slides before and after being set in and doing on the tooth bar 13, makes the switch branch by being arranged on snap close 11 and thrust keys 12 above deciliter handgrip 15, closes the location of position.Offer oblique tooth 22 on one end of tooth bar 13, inclined-plane slideway 20 and screens groove 17 are set on the other end.The connecting bolt 14 that is arranged on deciliter handgrip 15 is connected with insulated connecting rod 4, by seesawing of deciliter handgrip 15, drives the flexible of insulated connecting rod 4 and moving contact 3 interlocks and separating brake extension spring 16.Torsion spring 19 is set in the thrust key 12, and thrust key 12 can snap in 22 li of the oblique tooths of tooth bar 13 when making switch be in off-state, and could operate after must pressing thrust key 12 when closing a floodgate, to prevent misoperation.Owing to the effect of the oblique flank of tooth, thrust key 12 can be return from tooth bar 13 when disjunction is return.
Snap close 11 is along with deciliter handgrip 15 moves forward when closing a floodgate, smoothly enter screens groove 17 by the inclined-plane slideway 20 of tooth bar 13 bottoms, snap close 11 is positioned under the effect of spring 18 in the screens groove 17 on the tooth bar 3, with accuracy and the reliability that guarantees that switch closes a floodgate.The effect of contact over travel spring 21 is: when dynamic and static contact is in when just beginning contact condition, snap close 11 does not also slip in the screens groove 17, continue to push away deciliter handgrip 15 this moment forward, insulated connecting rod 4 begins to compress excess of stroke spring 21, after entering the screens groove Deng snap close 11, the contact over travel spring 21 that is compressed provides certain pressure to moving contact, makes dynamic and static contact keep excellent contact.Press snap close 11 during the switch separating brake, the separating brake action that finish switch at the effect lower moving contact 3 of tripping spring 16 along with insulated connecting rod 4 retreats rapidly this moment.
Operating process of the present utility model:
1. cable bond work
Charged during to aerial cable and buried cable overlap joint at need, the utility model action bars contact is in disconnected position (structure as shown in Figure 2).Wire clamp head 1 is hung on the aerial cable, and buried cable is connected with connection bolt 9 by other outside shorting stub, presses thrust piece 12, deciliter handgrip 15 is pushed away forward, in snap close 11 is stuck in the screens groove 17 of tooth bar 13; In the process that deciliter handgrip 15 pushes away forward (in the process of combined floodgate), drive insulated connecting rod 4 and moving contact 3 and also travel forward, make moving contact 3 engage (structure as shown in Figure 1) with fixed contact 2.Because deciliter operating mechanism of action bars can close a floodgate apace, so can not produce electric arc when the contact of moving contact 2, fixed contact 3.Simultaneously, capacity current in the buried cable, be introduced on the aerial cable by the connection bolt on outside shorting stub and the action bars 9, connecting line 5, moving contact 3, fixed contact 2, wire clamp head 1, this moment, aerial cable and buried cable formed the equipotential circuit by the utility model action bars, and operating personnel can be good with cable bond safely.After cable bond finishes, in the time of action bars need being withdrawed from, press snap close 11, because separating brake extension spring 16 is in elongated condition when closing a floodgate, separating brake extension spring 16 energy discharge when snap close 11 disengagings are spacing, moving contact 3 on the pulling insulated connecting rod 4 separates with fixed contact 2 rapidly to be return, and takes off and hangs over action bars on the aerial cable, finishes cable bond work.
2. cable is taken work apart
The charged extinguishing arc drainage procedure of the utility model bar is in that need are charged when taking outlet non-loaded cable buttock line apart, and operating personnel are on the insulating frame, and the action bars contact is in disconnected position (as shown in Figure 2).Wire clamp head 1 is hung on the aerial cable, buried cable is connected with connection bolt 9 by external connection line, press thrust piece 12, shift deciliter handgrip 15 onto closing position (as shown in Figure 1) forward, after operating personnel disconnect cable with the insulation scissors, snap close 11 on the push bar is separately return moving contact 2 rapidly, owing to exist capacitance current in the cable that disconnects, moving, fixed contact can produce electric arc separately the time, explosion chamber 6 is made by gas exhausted material, can decomposite gas under the high temperature action at electric arc, and utilize the gas extinguish arcs, the outer cover 7 that is with in the explosion chamber 6 can play the effect that does not produce outside arc light.After confirming that dynamic and static contact is separately, pull down external connection line on the connection bolt 9, take off and hang over action bars on the aerial cable, finish cable and take work apart.
