Abstract
The utility model relates to a structure for measuring the temperature of a lightning arrester. The structure comprises an insulating jacket for the lightning arrester, a nonlinear varistor core, and upper and lower flanges for fixing and sealing the core. The lower flange is equipped with a temperature measurement sensor thereon. By means of the structure, the change of the temperature in the lightning arrester can be measured in real time, enhancing the safe operation factor of the lightning arrester. In addition, the structure is convenient to assemble and manufacture.
Description
Technical field
The utility model relates to the lightning arrester technical field, more particularly relates to a kind of lightning arrester temperature survey structure, and it mainly is to cause that temperature increases problem after solving monitoring lightning arrester internal wetted.
Background technology
Lightning arrester uses at power transmission and transformation system in a large number as the power high voltage electric prospection equipment of a comparative maturity.But the explosion accident of lightning arrester happens occasionally, and the explosion accident more than 95% all causes owing to bad the making moist of lightning arrester self seal.Taked to continue to optimize hermetically-sealed construction, adopted the measure such as new material although respectively design production division, effect is not very remarkable, causes Explosion of on Arrester after operating lightning arrester sealing property forfeiture is usually arranged, and causes electric system ground connection power outage to occur.
Summary of the invention
Technical problem to be solved in the utility model is to provide a kind of lightning arrester inside temperature measurement structure for above-mentioned prior art present situation, measure in real time the temperature variation situation of lightning arrester inside by this structure, grasp lightning arrester and make internal temperature increase situation of change because making moist.
The utility model patent solves the problems of the technologies described above the technical scheme that adopts: this lightning arrester temperature survey structure, the insulating coating that comprises lightning arrester, place the non-linear voltage dependent resistor (VDR) core body at insulating coating center and the upper lower flange that is used for the fixing seal core body, its feature is equiped with temperature measurement sensor at described lower flange.This structure can be used to measure in real time the temperature variation situation of lightning arrester inside, has improved the safe operation coefficient of lightning arrester, is convenient to again Assembling Production.
Compared with prior art, the utility model has the advantage of: it can measure the temperature variation situation of lightning arrester inside in real time, judges whether the integral sealing of lightning arrester lost efficacy.The way of measuring leakage current of an arrester than traditional the time is more timely, quick, in order to take more ahead of time effective corrective action.
Description of drawings
Fig. 1 is the structural representation of the utility model embodiment.
Embodiment
Below in conjunction with accompanying drawing the utility model is described in further detail.
The utility model is to have set up a temperature measurement sensor at its lower flange on the basis of existing lightning arrester, can measure in real time the temperature variation situation of lightning arrester inside by this sensor, increase situation of change with the inner internal temperature that makes because making moist of timely grasp lightning arrester.
Concrete with reference to shown in Figure 1, this lightning arrester temperature survey structure, include the insulating coating 1 of lightning arrester, the inside center of insulating coating 1 is equipped with non-linear voltage dependent resistor (VDR) core body 2, upper and lower flange 3,4 fixing seals of this core body 2 by being contained in insulating coating two, and temperature measurement sensor 5 is contained on the lower flange 4.
