Description
Technical Field
The utility model relates to a transmission line tool, concretely relates to insulator chain prevents falling cluster device.
Background
Insulator strings of the power transmission line are generally made of porcelain insulators or composite insulators, and the bulb is fixed in the bowl head by the aid of locking pins of the insulator strings made of the porcelain insulators or the composite insulators. However, with the continuous enlargement of the scale of the power transmission line, the external environment is increasingly complex, and the extreme severe weather happens occasionally, the connection hardware fitting of the insulator string bears the compression and bending loads, the locking pin is pressed to deform and loses the limiting function, so that the ball head is separated from the socket head, and the insulator string falls. A large amount of manpower and time are spent by transmission line operation and maintenance personnel every year to regularly check whether the locking pins of the insulator strings are pressed and deformed so as to prevent the occurrence of disconnection accidents. Therefore, the anti-string-falling device for preventing the locking pin from losing efficacy is developed from the aspects of ensuring the safe and reliable operation of the power transmission line and improving the working efficiency, and has very important significance.
Chinese patent with publication number CN203276974U discloses a single-linkage V-shaped suspension string of +/-800 kV extra-high voltage direct current line anti-drop string composite insulator, which relates to the technical field of electric power, and comprises two suspension insulator strings, wherein the upper end of each suspension insulator string is connected with a lining type closed socket, the upper end of the lining type closed socket is connected with an EB hanging point hardware fitting through a right-angle hanging plate, the lower end of each suspension insulator string is connected on the lining type closed socket, the other end of the lining type closed socket is connected on the same suspension connecting plate through the right-angle hanging plate, the two suspension insulator strings are arranged in a V shape on the suspension connecting plate, an equalizing ring is respectively installed on a ball head rod of each suspension insulator string, and the suspension connecting plate is connected with a suspension clamp. Due to the stress specificity of the suspension insulator strings arranged in a V shape, if the suspension insulator strings are pressed seriously and inconsistently under the working condition of strong wind, the deformation ball socket connection of the locking pin can be caused to fail, the string falling accident of the steel feet of the composite insulator string from the socket hanging plate can be caused, and the stability under various working conditions can be enhanced. However, the insulator string structure is improved, the manufacturing cost is high, the insulator string is limited to a specific voltage class and a specific structure form, and the application range is limited.
