Abstract
The utility model relates to a drive connecting rod for a high-voltage isolating switch, which consists of a positive screw bolt, a positive screw nut, a negative screw bolt, a negative screw nut and a connecting rod, wherein the connecting rod is a steel pipe with a hollow structure, and the two ends of an inner cylinder of the steel pipe with the hollow structure are provided with screw threads which are respectively connected with the bolts; and the left side of the connecting rod is provided with the positive screw bolt, and the right side of the connecting rod is provided with the negative screw bolt. The parts of the drive connecting rod is changed into the direct connection by the inner screw thread of the circular steel pipe from the original outer threaded connection, thereby preventing the usability from being influenced since the screw threads are corroded when the screw threads run for a long time. The length of the drive connecting rod is adjusted by an outer screw hot galvanizing bolt, so that the operation is simple and convenient.
Description
Technical field: the utility model relates to a kind of isolating switch, refers more particularly to a kind of GW4 (35kV-110kV) high voltage isolator kinematic link that applies to use in the high-voltage fence.
Figure viewed from behind technology: at present, the GW4 that uses in electric power system (35kV-110kV) isolating switch has a bigger defective to be: the underdrive linkage component is with being threaded, and rust is dead easily, the normal use that influences kinematic link difficult in maintenance.
Summary of the invention: the purpose of this utility model just provides the strong high voltage isolator kinematic link of the good durability of a kind of performance.The purpose of this utility model is achieved in that a kind of high voltage isolator kinematic link, formed by positive silk bolt, forward leading nut, anti-silk bolt, anti-silk nut, connecting rod, it is characterized in that: connecting rod is the steel pipe of hollow-core construction, is respectively arranged with the screw thread of connecting bolt at the two ends of hollow-core construction steel pipe inner core; The left side of connecting rod is provided with positive silk bolt, is provided with forward leading nut between described positive silk bolt and the connecting rod; The right of connecting rod is provided with anti-silk bolt, is provided with anti-silk nut between described anti-silk bolt and the connecting rod.
The utility model effectively and has reasonably solved connecting rod screw thread corrosion phenomena, and cost remains unchanged, and has prolonged the useful life of isolating switch usefulness connecting rod greatly.
Description of drawings: Fig. 1 is a structural representation of the present utility model
1, positive silk bolt 2, forward leading nut 3, connecting rod 4, anti-silk nut 5, anti-silk bolt
Embodiment: the utility model is described in further detail below in conjunction with accompanying drawing
In the drawings, a kind of high voltage isolator kinematic link of the utility model, formed by positive silk bolt, forward leading nut, anti-silk bolt, anti-silk nut, connecting rod, it is characterized in that: connecting rod is the steel pipe of hollow-core construction, is respectively arranged with the screw thread of connecting bolt at the two ends of hollow-core construction steel pipe inner core; The left side of connecting rod is provided with positive silk bolt, is provided with forward leading nut between described positive silk bolt and the connecting rod; The right of connecting rod is provided with anti-silk bolt, is provided with anti-silk nut between described anti-silk bolt and the connecting rod.During concrete enforcement, kinematic link is connected with bolt and is also tight with nut.Connecting rod length can be appointed easy adjusting, and switch folding synchronism is regulated simple.Adopt this structure to effectively raise the durability at underdrive position.These parts are attached most importance to and are wanted parts in isolating switch design, have improved durability, the stability of isolating switch.Can not use because of surrounding environment corrosion influence.The kinematic link parts are made into directly to be connected by the round steel pipe internal thread by original external screw thread connection, have avoided screw thread corrosion in long-time running, influence serviceability.Because in the threaded adjusting process, original hot galvanized layer is destroyed on the connecting rod, at short notice can corrosion, it is difficult in maintenance to be directed at switch, regulates dumbly, now changes the pipe internal thread into and connects, by outer silk hot galvanizing bolt adjusting length, simple and convenient.
