Description
Technical field
The utility model belongs to power transformer field, relates in particular to a kind of insulator chain monitoring equipment.
Background technology
The safe operation that insulator chain is transmission line of electricity provides insulation support, but because porcelain vase surface long term is exposed in air, often can be subject to the pollution of filthy material, industrial and mineral smelting pollution source are along with the development of enterprise synchronously rises, the filthy directorial area of dividing can be used the liberalization of function and transition along with region, automobile exhaust pollution is also more on the rise along with the increase at full speed of the vehicles, its reason is that porcelain vase surface is under the effect of high voltage electric field, the very easily charged particle in absorbed air, in the time of environment and meteorological deterioration, along with the increase of humidity, airborne moisture will dissolve these charged particles, make the hurried decline generation of the insulation flashover fault on porcelain patticoat surface.Because foggy weather often occurs in boundless region, so the harm that this pollution flashover accident causes to society and mankind's activity is very serious.
Utility model content
Technical problem to be solved in the utility model is to provide one on insulator chain, to move, and can determine the insulator chain monitoring equipment of the position range on the insulator chain of current break.
The utility model is to realize like this, a kind of insulator chain monitoring equipment, this monitoring equipment comprises the first leakage current sensor and the second leakage current sensor, described the first leakage current sensor and described the second leakage current sensor are arranged on the diverse location with the fixture of guide rail, described the first leakage current sensor and described the second leakage current sensor are connected to the input end of single-chip microcomputer, the size of current of test insulator chain diverse location is also passed to single-chip microcomputer, the output terminal of single-chip microcomputer arranges communication module, by communication module, current value is transferred to remote monitoring indoor, described the first leakage current sensor and described the second leakage current sensor are for having forceps constructions formula, comprise the semi-circular tweezer arm of both sides, two tweezer arms connect by the free-ended plug terminal of tweezer arm.
Further, the first leakage current sensor and the second leakage current sensor are arranged on guide rail by slide block, the slide block of the first leakage current sensor and the second leakage current sensor is driven and is slided on guide rail by the first motor and the second motor respectively, described the first motor and the second motor are connected to respectively the output terminal of single-chip microcomputer by the first driving circuit and the second driving circuit, input end at single-chip microcomputer is connected with displacement transducer, described displacement transducer is arranged on and on guide rail, detects the first leakage current sensor and the position of the second leakage current sensor on guide rail.
The utility model compared with prior art, beneficial effect is: the utility model is set on insulator chain by two leakage current sensors, movement by two leakage current sensors on guide rail, thereby the electric current in the scope that two leakage current sensors of mensuration insulator chain limit, by dwindling two distances between leakage current sensor, further determine the position that leakage current occurs, between two leakage current sensors, one of them plays and corrects and the effect of limited range another, the utility model is installed on by insulator chain, simple in structure, practical, can effectively prevent the hurried decline generation of the insulation flashover fault on porcelain patticoat surface.
