Abstract
A hooking type grounding wire for a power transmission line comprises a grounding wire body. A hook is arranged at one end of the grounding wire body, a lifting press mechanism is arranged on the hook, a retaining sheet is hinged on one side at the lower end of the lifting press mechanism corresponding to a hook opening, and a pull rope is arranged at an operation end of the lifting press mechanism. A method for achieving flexible connection through the hooking type grounding wire comprises keeping the lifting press mechanism in a lifting state, and vertically extending the hooking type grounding wire downwards; enabling the power transmission line to enter the hook; putting the lifting press mechanism down; achieving sealing connection of the power transmission line; lifting the lifting press mechanism, and opening the hook opening; and withdrawing the hooking type grounding wire for the power transmission line. Due to the distance between the adjustable retaining sheet and the tail end of the hook, that the retaining sheet cannot retain the hook caused by power transmission line interference in the hook is prevented, the connection is reliable, and requirements of dynamic stability tests can be met. The hook connection is used, so that a gap exists between the hook and the power transmission line in the hook, and damage to cables due to abrasion is avoided.
Description
Technical field
The present invention relates to a kind of power transmission line hook-hang type earth connection.
Background technology
Being flexible coupling is the connected mode of a kind of power transmission line earth connection and power transmission line.Make the front end of power transmission line earth connection in this way with earthing clamp, during connection, hold power transmission line to realize being connected of power transmission line earth connection and power transmission line by earthing clamp.
The shortcoming of this syndeton is: it is unreliable with being connected of power transmission line that the holding of earthing clamp puted forth effort little then power transmission line earth connection, is difficult to satisfy the requirement of moving stability test; Holding of earthing clamp puted forth effort greatly then to be difficult at the power transmission line extension, torn power transmission line earth connection and the wearing and tearing that can strengthen wire open.
Summary of the invention
The technical problem to be solved in the present invention provides reliable, the satisfied moving stability test requirement of a kind of connection, hangs, tears open easily, the power transmission line hook-hang type earth connection that the power transmission line wearing and tearing are little and the method that is flexible coupling with its realization.
A kind of power transmission line hook-hang type earth connection, comprise the earth connection body, its special character is: the end at the earth connection body is provided with hook, be provided with and lift pressing mechanism at hook, a side corresponding with the hook opening in the lower end that lifts pressing mechanism is hinged with catch, is provided with stay cord in the operating side that lifts pressing mechanism.
The described pressing mechanism that lifts is by pressing seat, press pressing cap, press core, press wheel, press bar and being sleeved on the spring of pressing on the bar in the seat and form by placing successively on lower, along the circumferential direction be provided with projection pressing the wheel outside, along the circumferential direction be misplaced the different axial notch of length pressing an inwall.
Described stay cord with press cap and be connected, described hook is with to press the cap lower surface affixed, described earth connection body is electrically connected with pressing.
Described catch with press the seat hinged.
Lifting under the state that pressing mechanism puts down, the length of catch greater than catch with lift the distance of pressing mechanism pin joint with the hook distal point; Under the state that lifts the pull-up of pressing mechanism, the length of catch is less than catch and the distance that lifts pressing mechanism pin joint and hook distal point place horizontal plane.
A kind of method that is flexible coupling with the realization of power transmission line hook-hang type earth connection, its special character is that concrete steps are as follows:
1, make and lift pressing mechanism and keep the pull-up state, towards power transmission line position to be connected, downward drawdown power transmission line hook-hang type earth connection;
2, when the hook distal point was positioned at the power transmission line below, mobile power transmission line hook-hang type earth connection made the opening of hook towards power transmission line, upwards lifts power transmission line hook-hang type earth connection, and power transmission line is entered in the hook;
3, the pulling stay cord lifts pressing mechanism and is put down;
4, slowly carry the earth connection body, make the earth connection body beat arc, hook moves towards to change with the earth connection body and reverses, and the opening direction of hook is downward, and catch hangs under action of gravitation, and rides on the hook, realizes the sealing of power transmission line is connected;
5, after electric operating is finished, reclaim the earth connection body, make the earth connection body perpendicular to the ground;
6, the pulling stay cord lifts pressing mechanism and is raised, and catch hangs under action of gravitation, and the opening of hook is opened;
7, put down hook, make the hook distal point be positioned at the power transmission line below, to the mobile power transmission line hook-hang type earth connection in one side, regain this power transmission line hook-hang type earth connection.
The invention has the beneficial effects as follows:
1, lifts pressing mechanism owing to being provided with, can regulate the distance between catch and the hook end, avoid causing catch can't pin hook because linking up with interior power transmission line interference, connect reliably, can satisfy the requirement of moving stability test.
2, owing to adopt hook to connect, there is the slit between the power transmission line in hook and the hook, avoided because of the friction damage cable.
