Abstract
The utility model discloses a contact finger structure for the outdoor high voltage disconnected switch in the power transmission and transforming system. The structure is equipped with an arch contact finger support (5) between the two wafers of the contact fingers, and with the holes in the contact finger wafer (3) and the arch contact finger support(5) respectively. The rotation contact for the two is through the axle pin (6) of the hole, and the compressed spring is between the two sides of the axle pin (6) and the two sides of the contact finger(3). This connecting structure uses the pushing compressed spring to provide the pressure to help the connection of the contact and the contact finger, so as to avoid the carrying of the pulling spring and to reduce the heating of the contact and contact finger effectively.
Description
Technical field
The utility model relates to a kind of outdoor high-voltage isolating switch of power transmission and transformation system, and is special relevant with the fingertip structure of this switch.
Background technology
Outdoor high-voltage isolating switch is a circuit deciliter device commonly used in the power transmission and transformation system.At rated voltage 40.5,126,252kV, commonly used in the power transmission and transformation system of three-phase alternating current 50Hz have two kinds of GW4 and GW5.The pressure that pull-type fingertip spring provided in its fingertip sheet of these two kinds of isolating switches that use adopted at present is connected contact with contact, this structure is in the isolating switch long-time running, and the spring current-carrying generates heat the contact of ablating easily.
The utility model content
The utility model is spring current-carrying, the heating that exists at pull-type fingertip spring structure in the above-mentioned switch, and the disadvantage of the contact of ablating is easily designed a kind of easy for installation, isolating switch fingertip structure that can solve the current-carrying problem.
The technical solution adopted in the utility model is that an arc fingertip bracing frame is set between two fingertip sheets, correspondence is provided with through hole on fingertip sheet and arc fingertip bracing frame, and make the two movable contact by the pivot pin that passes through hole, be respectively arranged with stage clip between the two ends of pivot pin and the fingertip sheet outside.
The fingertip structure that the utility model provides adopts the external-compression type structure, and spring does not possess the condition of current-carrying, and contact pressure is steady in a long-term reliable, can guarantee that fingertip and the good of contact contact.Adopt special mould clamp during installation, easy for installation.
Description of drawings
Fig. 1 is the fingertip structural representation of existing GW4, GW5 switch;
Fig. 2 is the structural representation of an embodiment of the utility model isolating switch fingertip structure.
Embodiment
The utility model is described in further detail below in conjunction with accompanying drawing.
Figure acceptance of the bid note is respectively: 1, contact tube (row) 2, spring 3, fingertip sheet 4, contact 5, arch form supporting frame 6, pivot pin
As shown in Figure 2, between the fingertip sheet, be provided with an arc fingertip bracing frame 5, correspondence is provided with through hole on two fingertip sheets 3 and arc fingertip bracing frame 5, and make the two movable contact by the pivot pin 6 that passes through hole, respectively be provided with a stage clip 2 between the outside of the two ends of pivot pin 6 and fingertip sheet 3.Stage clip 2 is a stainless steel spring.This syndeton spring 2 is arranged on the outside of fingertip sheet 3, and spring does not possess the condition of current-carrying, is difficult for heating ablation contact, makes contact pressure steady in a long-term reliable, guarantees system safety operation.
Claims (1)
1, a kind of outdoor disconnector fingertip structure, comprise spring (2), fingertip sheet (3), arch form supporting frame (5), pivot pin (6), it is characterized in that: an arc arch form supporting frame (5) is partly arranged at fingertip, be provided with through hole at two fingertip sheets (3) and the last correspondence of arc fingertip bracing frame (5), and make the two movable contact by the pivot pin (6) that passes through hole, respectively be provided with a stage clip (2) between the outside of the two ends of pivot pin (6) and fingertip sheet (3).
