Abstract
The utility model discloses a protective cover of an arrester online monitor. The protective cover is characterized in that the protective cover is composed of an umbrella-shaped rubber cap and an annular aluminum strip, two side walls of the aluminum strip are fixed onto the middle of the inner wall of the umbrella-shaped rubber cap through insulating screws, the bottom end of the annular aluminum strip is open and is provided with downward bending mouth edges, a screw fixed with the housing of an arrester online monitor is disposed on the downward bending mouth edges, and a hoisting hole is disposed on the top end of the umbrella-shaped rubber cap. The protective cover of the arrester online monitor is simple in structure, low in manufacturing cost and easy to install, and can be used for effectively preventing the arrester online monitor from being eroded or damaged when wind, rain, snow and dropping objects occur, thereby ensuring reliable operation of the arrester online monitor.
Description
Technical field
The utility model relates to a kind of protective device that transformer substation arrester on-line monitoring instrument is used, a kind of lightning arrester on-line monitoring instrument protective cover specifically, be mainly used on the main equipment such as bus, main transformer, in the time having wind, sleet and object to fall, can prevent erosion and destruction to lightning arrester on-line monitoring instrument and coupling bolt thereof, the replacing when guaranteeing the sensitive work of lightning arrester on-line monitoring instrument and breaking down.
Background technology
The lightning arrester on-line monitoring instrument using at present, generally to be serially connected in arrester ground loop, be lifted on mounting bracket, by the variation of milliammeter and operation counter, can judge whether lightning arrester inside makes moist, the situations such as whether element is abnormal, provide reliable data to the running quality of lightning arrester, the generation of Accident prevention.The existing deficiency of this lightning arrester on-line monitoring instrument is: the one, due to being exposed in air of entirety, be subject to for a long time the erosion of wind, sleet, the set bolt of lightning arrester on-line monitoring instrument can get rusty, the replacing of lightning arrester on-line monitoring instrument when impact has fault; The 2nd, to there being individually the lightning arrester on-line monitoring instrument of poor sealing, if rainwater enters its inside, also can cause the corrosion of inner precision element and damage and affect use; The 3rd, in maintenance process, can run into unavoidably the objects such as Work tool and fall to monitor at the scene, the destruction that it is caused to strike, can cause breaking of lightning arrester on-line monitoring instrument screen when serious.
Known by retrieving, have not yet to see the report that lightning arrester on-line monitoring instrument is added to protective cover.
Summary of the invention
The purpose of this utility model be to provide a kind of simple in structure, cost of manufacture is low, easily install, in the time there is wind, rain, snow and dropped object, can effectively prevent that lightning arrester on-line monitoring instrument from suffering erosion and destroying, guarantee the lightning arrester on-line monitoring instrument protective cover of lightning arrester on-line monitoring instrument reliability service.
In order to reach above object, the technical scheme that the utility model adopts is: this lightning arrester on-line monitoring instrument protective cover, it is characterized in that: it is made up of umbrella shape rubber cap and annular aluminum strip, the two side of annular aluminum strip is fixed on the inwall middle part of umbrella shape rubber cap by insulation screw, described annular aluminum strip bottom end opening, and be provided with lower curved mouth edge, on lower curved mouth edge, be provided with the bolt fixing with lightning arrester on-line monitoring instrument housing; The top of described umbrella shape rubber cap is provided with hole for hoist.
The utility model is also implemented by following measure: in described umbrella shape rubber cap, angle is 40-60 degree, is highly 15-25cm.
The beneficial effects of the utility model are: this lightning arrester on-line monitoring instrument protective cover, simple in structure, cost of manufacture is low, easily install, in the time there is wind, rain, snow and dropped object, can effectively prevent that lightning arrester on-line monitoring instrument from suffering erosion and destroying, guarantee lightning arrester on-line monitoring instrument reliability service.
Brief description of the drawings
Fig. 1 is that axis of no-feathering of the present utility model is to cross-sectional schematic.
In figure: 1, umbrella shape rubber cap; 2, annular aluminum strip; 3, insulation screw; 4, lower curved mouth edge; 5, bolt; 6, hole for hoist.
Embodiment
Make the utility model with reference to Fig. 1.This lightning arrester on-line monitoring instrument protective cover, it is characterized in that: it is made up of umbrella shape rubber cap 1 and annular aluminum strip 2, the two side of annular aluminum strip 2 is fixed on the inwall middle part of umbrella shape rubber cap 1 by insulation screw 3, described annular aluminum strip 2 bottom end openings, and be provided with lower curved mouth along 4, be provided with the bolt 5 fixing with lightning arrester on-line monitoring instrument housing in lower curved mouth on along 4; The top of described umbrella shape rubber cap 1 is provided with hole for hoist 6.While using the utility model, the lower curved mouth that the housing of lightning arrester on-line monitoring instrument is put into annular aluminum strip 2 bottoms is along 4, fixing by bolt 5, the hole for hoist of umbrella shape rubber cap 16 is lifted on mounting bracket, the extension line of lightning arrester on-line monitoring instrument is serially connected in arrester ground loop, install, like this, because center of gravity is lower, no matter wind blow, sleet, can not enter in lightning arrester on-line monitoring instrument, meanwhile, avoid Work tool in the time of maintenance to drop on lightning arrester on-line monitoring instrument yet.
As improvement of the present utility model: the described interior angle of umbrella shape rubber cap 1 is 40-60 degree, is highly 15-25cm, so that be advisable in the middle and lower part that lightning arrester on-line monitoring instrument can be in umbrella shape rubber cap 1.
