Abstract
The utility model relates to a monitoring failure indicator for line lightning arresters. The utility model solves the problem that the prior art can not obviously prompt the failure position and the present status of the lightning arrester to effectively ensure nonserviceable line lighting arresters to be found, maintained and replaced in time and to ensure the security of the normal operation of the transmission lines. The utility model aims to develop a novel and practical fault indicator for line lightning arresters, and the utility model has the technical structure that the utility model comprises a disengaging device and an upper and a lower wire connecting terminals 7 and 1, wherein the periphery of the disengaging device 3 is wound with an indicating ribbon 4, and the outer side of the disengaging device 3 is also provided with a housing 5; the upper and the lower wire connecting terminals 7 and 1 are separately through arranged on the upper and the lower end surfaces of the housing 5.
Description
Affiliated technical field:
The utility model relates to lightning arrester monitoring, the faulty indication instrument on the circuit, specially refers to a kind of leakage conductor fault detector.
Background technology:
Usually on transmission line, adopt the method that lightning arrester is installed at present both at home and abroad, ensure the security of operation of transmission line, improve the lightning withstand level of transmission line, reduce the power outage that causes because of thunderbolt.Fault detector is the equipment that is used for lightning arrester is carried out faulty indication.Because transmission line is built personnel's rareness, area with a varied topography mostly in, so the monitoring of the leakage conductor of installing on the transmission line just becomes a difficult problem, and whether leakage conductor can operate as normal become hidden danger again simultaneously.But the problem that existing faulty indication exists: can not observably point out the position of the lightning arrester that is out of order, therefore can not effectively ensure when leakage conductor is nonserviceabled, in time be found with maintenance in time and change, can't guarantee the normal security of operation of transmission line.
Summary of the invention:
The purpose of this utility model is to develop a kind of leakage conductor fault detector, to overcome the position present situation problem that can not observably point out the lightning arrester that is out of order that prior art exists, thereby can effectively ensure when leakage conductor is nonserviceabled, in time be found and maintenance replacing in time, guarantee the normal security of operation of transmission line.
Technical solution of the present utility model:
The fault detector that leakage conductor is used, comprise release unit and upper and lower binding post 7,1, it is characterized in that: release unit 3 peripheries are arranged with indication ribbon 4, and release unit 3 outsides also are provided with housing 5, and upper and lower binding post 7,1 is arranged in the upper and lower end face of housing 5 respectively.
The lower surface of above-mentioned housing 5 is bottom end cover 2 independently.Be more convenient for coming off.
Technical solution of the present utility model also comprises:
Socket insulation full skirt 6 on upper connecting terminal 7, it is arranged at the outside, upper surface of housing 5.
Above-mentioned release unit 3 is heat explosion type release units.
Advantage of the present utility model and effect: when transmission line produces the high voltage heavy current because of thunder lightning or other reasons, the lightning arrester work of installation has ensured the security of operation of transmission line; When transmission line produces the high voltage heavy current, during the lightning arrester cisco unity malfunction installed, the fault detector that leakage conductor is used is at the initial stage that produces the high voltage heavy current, just start working and ignite heat explosion type release unit 3, the warning of being scattered of indication ribbon 4, people can in time be found, the maintenance personal overhauls the replacing lightning arrester as early as possible.The utility model can make lightning arrester withdraw from the circuit operation when the lightning arrester fault, does not influence the normal operation of circuit, has further improved the lightning withstand level of transmission line, has guaranteed the security of operation of transmission line.
Description of drawings:
Accompanying drawing is whole sectional block diagram.
Number in the figure explanation: the 1-lower connecting terminal, the 2-end cap, the 3-release unit, 4-indicates ribbon, 5-housing, the 6-full skirt that insulate, 7-upper connecting terminal.
Embodiment:
Referring to accompanying drawing, the high and low pressure circuit connects upper and lower binding post 7,1 respectively, connect heat explosion type release unit 3 between the upper and lower binding post 7,1, release unit 3 periphery sockets, bonding or other modes are arranged with can open the colour indication ribbon 4 that is scattered, adorn the upper and lower end face that is arranged in housing 5 on the upper and lower binding post 7,1 respectively, the lower surface of said housing 5 is the bottom end cover 2 that independently is connected with housing 2.Socket insulation full skirt 6 on upper connecting terminal 7, it is arranged at the outside, upper surface of housing 5.Need to prove: when the housing 5 that has upper end cover during for insulator, when perhaps its upper end cover is insulator, omit the outside socket connect insulation full skirt 6 can simplified structure.
Operation principle is: when the lightning arrester cisco unity malfunction installed, the fault detector that leakage conductor is used is at the initial stage that produces the high voltage heavy current, just start working and ignite heat explosion type release unit 3, upper and lower binding post 7 separates, simultaneously because of gas moment expanded by heating in the housing, cause bottom end cover 2 under impulsive force, to break away from housing, colored indication ribbon 4 is scattered and reports to the police, people at a distance can in time be found, lightning arrester is changed in maintenance personal's maintenance in time in the shortest time, guarantees the security of operation of transmission line.
