Description
Technical field
The utility model relates to electric power system isolating switch technical field, the rotatable insulation of the composite type band disconnecting link that especially a kind of isolating switch is used main shaft.
Background technology
The electric power system isolating switch is that the rotation by disconnecting link realizes operating states switchings such as combined floodgates, isolation, generally speaking, the bottom of disconnecting link will be hinged with the binding post on the line bank of isolating switch bottom, disconnecting link rotates along pin joint again, for disconnecting link can be rotated along pin joint, traditional way is to utilize insulated connecting rod mechanism of rotating shaft drive and disconnecting link middle part to be hinged, utilize pushing away and draw disconnecting link being rotated of insulated connecting rod mechanism, the problem that this structure exists is that mechanism is complicated, the reliability of action is lower, and volume is unfavorable for the isolating switch miniaturization greatly; A patent No. is called " three station isolation earthing switch " for the ZL200720008552.2 name utility model patent was disclosed on September 10th, 2008, its content discloses a kind of mechanism that is driven the disconnecting link rotation by an eradication edge main shaft, this mechanism helps the miniaturization of isolating switch, the mould that needs when but this insulation main shaft is made is bigger, manufacturing equipment is required high, rate of finished products is also low, and manufacturing cost is higher.
The utility model content
The technical problems to be solved in the utility model provides the rotatable insulation of a kind of composite type band disconnecting link main shaft, easily makes, cost is low, easy for installation again.
For achieving the above object, the technical solution of the utility model is: the rotatable insulation of a kind of composite type band disconnecting link main shaft, comprise disconnecting link, insulation main shaft, the insulation main shaft is formed by three insulation nodal axisns and two end matchings, each insulation nodal axisn is provided with a connecting lever, through hole perpendicular to the insulation joint axis is arranged on the connecting lever, and disconnecting link partly is installed in the described through hole.
Further, the spring bumper cover of uniform voltage function is equipped with in both sides, described disconnecting link top, and the bottom of disconnecting link is provided with cross through hole, is provided with stage clip between the bottom of disconnecting link and the insulation nodal axisn, makes disconnecting link tightr with engaging of binding post contact, reduces contact resistance.
Further, the through hole on the described connecting lever is a square through hole, makes things convenient for disconnecting link to install.
The rotatable insulation of above-mentioned composite type band disconnecting link main shaft, described insulation nodal axisn one end has docking recess, and the other end has the butt joint projection; Described two first ends of end have docking recess, and one one end has the butt joint projection, convenient splicing mutually.
The utility model thoroughly does away with the edge main shaft to one and is divided into five sections and is formed by three insulation nodal axisns and two end matchings, and each segment body is long-pending less, and required mfg. moulding die is just less, manufacturing equipment is required also low, therefore makes easily, and cost is low.
Because on the connecting lever of each insulation nodal axisn a through hole perpendicular to the insulation joint axis is arranged, disconnecting link is enclosed within and just can drives the disconnecting link rotation on the described through hole, and is therefore easy for installation again.
Utilize the docking recess and the other end of insulation nodal axisn one end to have the butt joint projection, the convenient nodal axisn that insulate in twos splices mutually, two first ends of end have docking recess, and one one end has the butt joint projection, make two terminations easily splice the two ends at the insulation nodal axisn.

Embodiment
Below in conjunction with accompanying drawing and concrete execution mode the utility model is described in further detail.
Fig. 1, Fig. 2, shown in Figure 3, the rotatable insulation of a kind of composite type band disconnecting link main shaft, comprise disconnecting link 1, insulation main shaft 2, insulation main shaft 2 is spliced by three insulation nodal axisns 21 and two terminations 22,23, each insulation nodal axisn 21 is provided with a connecting lever 211, through hole 211a perpendicular to insulation nodal axisn 21 axis is arranged on the connecting lever 211, and disconnecting link 1 part is installed among the described through hole 211a.
The spring bumper cover 3 of uniform voltage function is equipped with in both sides, disconnecting link 1 top, and the bottom of disconnecting link 1 is provided with cross through hole, is provided with stage clip 4 between the bottom of disconnecting link 1 and the insulation nodal axisn 21, makes disconnecting link 1 tightr with engaging of binding post contact.
Fig. 3 shows that further the via design on the described connecting lever 211 is a square through hole, makes things convenient for disconnecting link 1 to install.
Described insulation nodal axisn 21 1 ends have docking recess, and the other end has the butt joint projection; 22,23 1 ends in described two terminations have docking recess, and one one end has the butt joint projection.
When the utility model uses, utilize two termination point casings to be connected on the housing of isolating switch, one of them termination also is connected with rotating mechanism, the binding post of the bottom of disconnecting link and isolating switch bottom is hinged, the insulation main shaft just can be driven by rotating mechanism, thereby makes disconnecting link rotate the switching of the operating states such as combined floodgate, isolation of realization isolating switch.
Below only be preferred embodiment of the utility model, the length of insulation nodal axisn and two terminations can change according to actual needs, and those skilled in the art is so long as make the protection range that the change of unsubstantiality all falls into this case.
