Abstract
The utility model relates to a touch finger for an AC high-voltage isolating switch, consisting of a transmission connecting rod, a conductive tube, touch fingers, a contact, a wiring board and an original-phase transmission connecting rod. The method is as follows: the transmission connecting rod is arranged above the conductive tube, the touch fingers are arranged at two sides of the conductive tube, the touch fingers are connected with the contact, and the wiring board and the original-phase transmission connecting rod are respectively arranged below the contact, so that the defects that the pressure of the touch finger is reduced, the overheat is caused by the rising of the contact resistance, the temperature of the conductive tube is increased and the like are solved. The touch finger is simple in structure and convenient in installation.
Description
Technical field: the utility model relates to a kind of isolating switch, refers more particularly to a kind of GW4 (35kV-110kV) ac high-voltage isolating switch fingertip that applies to use in the high-voltage fence.
Background technology: at present, the defective of the GW4 that uses in electric power system (35kV-110kV) isolating switch maximum is: the poor durability that goes up conducting position, because of its fingertip spring is in tension state fatigue for a long time, water inlet easily in the fingertip in the middle of adding, make spring seriously get rusty, cause sensing finger pressure to descend, it is overheated that the contact resistance rising causes, the temperature rise of last conduction increases.Former stripe shape fingertip is in gate-dividing state for a long time and is subjected to air pollution, forms the higher cover layer of resistivity on the contact-making surface because surface oxidation and soil act on, and causes contact overheated after making combined floodgate.
Summary of the invention: it is more stable that the purpose of this utility model just provides a kind of performance, the high voltage isolator fingertip that durability is stronger.The purpose of this utility model is achieved in that ac high-voltage isolating switch fingertip, formed by kinematic link, contact tube, fingertip, contact, terminal block, this phase kinematic link, it is characterized in that: the top of contact tube is provided with kinematic link, both sides at contact tube are provided with fingertip, described fingertip is connected with contact, is respectively arranged with terminal block and this kinematic link mutually below contact.
The utility model is simple in structure, and is easy for installation, and effectively having solved because of fingertip pollutes increases this problem of loop resistance.
Description of drawings: Fig. 1 is the utility model structural representation
1, kinematic link 2, contact tube 3, fingertip 4, contact 5, terminal block 6, this phase kinematic link
Embodiment: utility model is described further below in conjunction with accompanying drawing
In the drawings, the utility model ac high-voltage isolating switch fingertip, formed by kinematic link, contact tube, fingertip, contact, terminal block, this phase kinematic link, it is characterized in that: the top of contact tube is provided with kinematic link, both sides at contact tube are provided with fingertip, described fingertip is connected with contact, is respectively arranged with terminal block and this kinematic link mutually below contact.The material of fingertip adopts chromium-bronze during concrete enforcement, good springiness, and the fusing point height, material is hard, has self clamping force when folding clamps, and material itself resiles behind the separating brake, is out of shape little.These parts are main core technology in the isolating switch design, have improved durability, the stability of isolating switch.The conduction fingertip is made by original common copper material, changes into the chromium-bronze forming materials forming, and material itself has characteristics such as high resiliency high-melting-point.The fingertip external form makes finger type fingertip into by original stripe shape fingertip, and originally line contact design changes a contact design into, has improved the automatically cleaning ability of fingertip.
