Abstract
The utility model relates to a static contact of a high-voltage switch, which consists of two rows of relatively-arranged plate contact fingers. A pullback spring is arranged between the two rows of contact fingers. One end of one row of the contact fingers and one end of the other row of the contact fingers are held by the pullback spring and conducted with the relative two sides of the conductor end of a switch. The relative sides of the other ends of the two rows of the contact fingers are the ends contacted and conducted with a moving contact. Locating bracing plates are installed on the relative two sides of the central part of the two rows of the contact fingers in an inserting way. The utility model has the advantages that the contact fingers of the static contact of the high-voltage switch in the proposal are arranged in two rows, the occupied area is small and the structure is compact; and the moving contact is added between the two rows of the contact fingers when the moving contact is at the closing position, the contact area between the static contact and the moving contact is large and the conductibility is good.
Description
Technical field
The utility model relates to a kind of high-voltage switch gear fixed contact, especially for the high-voltage switch gear fixed contact of isolation, earthed switch.
Background technology
The version of isolation, earthed switch mainly contains two kinds in the market: a kind of is that moving contact is done rectilinear motion, and fixed contact adopts the plum blossom fingertip, and this structure is led to good fluidity, but volume is bigger; Another kind is that moving contact rotates, and fixed contact adopts the watchband fingertip, and this structure is through-flow, and the property difference is a little, but volume is less.Obviously, above-mentioned two kinds of forms all can not satisfy the good requirement of the volume rill general character.
The utility model content
The purpose of this utility model provides a kind of high-voltage switch gear fixed contact, can not satisfy the good requirement of the volume rill general character in order to solve existing contact.
For achieving the above object, the utility model adopts following technical scheme: a kind of high-voltage switch gear fixed contact, this fixed contact comprises the fingertip in the form of sheets that two rows are oppositely arranged, be provided with extension spring between two row's fingertips, one end of two row's fingertips is by the relative both sides of extension spring clamping conducting in the switch end conductor, the opposite side of two row's fingertip other ends is to contact conduction terminal with moving contact, and the relative both sides at two row's fingertip middle parts are fitted with the location fagging.
Every row's fingertip comprises at least two branch fingertips that are arranged side by side, and is provided with the fingertip dividing plate between the fingertip in adjacent two minutes on every row's fingertip, and per two are provided with extension spring between the branch fingertip relatively.
Fingertip was in the separating brake position away from the rotation axle head away from the switch conductor end towards moving contact in described minute.
The described fingertip outside is provided with radome.
Be provided with insulating barrier between described fingertip and the radome.
The high-voltage switch gear fixed contact of such scheme, its fingertip are two rows and are provided with, and it is little to take up room, compact conformation; Be sandwiched in when moving contact is in closing position between two row's fingertips, the contact-making surface between dynamic and static like this is big, and circulation is good.
Every row's fingertip of this fixed contact is made up of at least two branch fingertips, is provided with extension spring between the per two corresponding branch fingertips, and extension spring strains at two and divides fingertips relatively, can guarantee to be in high-voltage switch gear fixed contact and moving contact full contact when closing a floodgate.Be provided with a location-plate between two row's fingertips, location-plate is plugged on fingertip, and the location-plate that is plugged on the fingertip has prevented that the situation of dividing fingertip location dislocation to occur from taking place.Divide fingertip to be in the separating brake position away from the rotation axle head towards moving contact, can guarantee like this that moving contact can be conducted with each minute fingertip in the less angle of rotation to contact away from the switch conductor end.The outside of fingertip is provided with radome, and radome has effectively improved the electric field of fixed contact position; Between radome and contact, be provided with insulating barrier, prevent that contact and radome are conducted.Be provided with dividing plate between per two fingertips, dividing plate is kept apart the insulation of per two adjacent fingertips, has avoided situation about reducing by face because of the electric current that connection caused between the fingertip like this, thereby has strengthened the current lead-through of this contact.
Description of drawings
Fig. 1 is a structural representation of the present utility model;
Fig. 2 is the B-B sound view of Fig. 1;
Fig. 3 is that the A of Fig. 2 is to view.
Embodiment
Fig. 1, Fig. 2, high-voltage switch gear fixed contact shown in Figure 3 comprise the fingertip that two rows are connected with switch conductor 1, every row's fingertip is formed by five branch fingertips 4, two rows divide and to be provided with between the fingertips 4 and each minute location-plate 3 of being connected of fingertip 4, location-plate 3 is plugged in the location-plate mounting groove of each minute fingertip, and the position-limiting action by location-plate can prevent from the position changing of the relative positions to occur between five branch fingertips 4 of every row.Be provided with extension spring 7 between the per two relative branch fingertips 4, link together by pin 8 between extension spring 7 and the branch fingertip 4, extension spring is in extended state always, per two relative branch fingertips 4 all have the inside trend of tightening up under the effect of extension spring, can guarantee the reliability that moving contact contacts with fixed contact when closing a floodgate like this.Each minute, fingertip 4 all was in the separating brake position away from the rotation axle head towards moving contact 6 away from the switch conductor end, and moving contact rotates a less angle and can be conducted with each minute fingertip 4 and contact when closing a floodgate like this.Divide the outside of fingertip 4 that the radome 2 that is fixed on the switch conductor 1 is installed two rows, radome insulate mutually with fingertip and switch conductor, and radome has effectively improved the voltage characteristic at fixed contact place.Location-plate 3 is fixed together with radome 2.Be provided with first dividing plate 9 between radome and the branch fingertip, be provided with second partition 5 between the per two adjacent fingertips.
