Abstract
The utility model discloses a bar-type self-operated conductive structure used for a high-voltage disconnecting switch. Connecting terminals are clamped on a left wire holder and a right wire holder; the right end of the left wire holder is fixedly connected with a left conductive tube; the left end of the right wire holder is fixedly connected with a right conductive tube; a contact finger seat is fixed at the right end of the left conductive tube; a contact terminal seat is fixed at the left end of the right conductive tube; a contact finger fixed on the contact finger seat adopts an elastic bar-type structure with a curve front end; a contact terminal fixed on the contact terminal seat adopts a pillar-type structure with a groove; and when the conductive structure is switched on, the contact finger is pressed on the groove of the contact terminal. The utility model has the advantages of simple structure, stable and reliable conductivity, and convenient debugging and maintenance.
Description
Technical field
The utility model relates to a kind of conductive structure, the conductive structure that especially a kind of high voltage isolator is used.
Background technology
The conductive structure that existing high voltage isolator is used, fingertip and contact blade keep in touch pressure with spring, and because of the through-flow heating of spring makes isolating switch fingertip, contact generate heat, and the surface area of contact is less, heat dispersion is bad, and the stability and reliability of conduction can not get guaranteeing.
Summary of the invention
For solving the problem of above existence, the utility model provides a kind of high voltage isolator bar type self-operated type conductive structure, and its technical scheme of taking is:
This structure comprises binding post, left side junction block, left side contact tube, the fingertip seat, fingertip, contact, contact base, right contact tube and right junction block, binding post is connected to respectively on left junction block and the right junction block, the fixedly connected left contact tube of right-hand member of left side junction block, the fixedly connected right contact tube of left end of right junction block, the right-hand member of left side contact tube is the fingertip seat fixedly, the left end fixed contact seat of right contact tube, the fingertip that is fixed on the contact base is front end bending and rubber-like bar type structure, the contact that is fixed on the contact base is the pole structure that has groove, and fingertip is crimped on the groove of contact during combined floodgate.
Fingertip guarantees contact pressure by the strain of itself, has cancelled and has utilized spring to keep in touch the structure of pressure, thereby thoroughly solved the problem because of the through-flow heating isolating switch of spring fingertip, contact heating.The surface area of contact is bigger, has good heat-sinking capability, has eliminated the influence of kelvin effect, has good automatically cleaning ability simultaneously, and it is darker that this structure contact inserts the degree of depth of fingertip, has favorable conductive stability and reliability.
Therefore the utlity model has simple in structure, conduction is stable and reliable, debugging maintenance advantage easily.
Description of drawings
Accompanying drawing is a structural representation of the present utility model.
Embodiment
Below in conjunction with accompanying drawing the utility model is described further:
As shown in the figure, binding post 1 is connected to respectively on left junction block 2 and the right junction block 9, the fixedly connected left contact tube 3 of right-hand member of left side junction block 2, the fixedly connected right contact tube 8 of left end of right junction block 9, conducting rod adopts aluminium-alloy pipe high-intensity and that have a high conductivity to make, adopt welding manner between conducting rod and the junction block, the right-hand member of left side contact tube 3 is fingertip seat 4 fixedly, the left end fixed contact seat 7 of right contact tube 8, fingertip 5 is fixed on the contact base 7, fingertip 5 is the bandy bar type structure of front end, the Cu alloy material that employing has good and stable elasticity and excellent conducting performance and thermal stability processes, and contact 6 is fixed on the contact base 7, and contact 6 is for having the pole structure of groove, form through cold working by red copper bar, have excellent mechanical intensity.
In the divide-shut brake process, when post insulator drove contact 6 and fingertip 5 half-twists, they were by a kind of sliding motion divide-shut brake.When closing a floodgate, contact 6 rotates with fingertip 5 and contacts, the front end of the two groups of fingertips 5 in front and back is crimped in the groove of contact 6, their folders tightly surround contact 6, therefore have automatically cleaning and clamp function certainly in the making process, when short circuit current passed through, the electromagnetic force that fingertip 5 is subjected under effect of electric field also was a clamping direction, thereby can guarantee optimum performance under the electrodynamic action that is caused by short circuit current.
