Abstract
The utility model discloses an expander oil level monitoring device for a current transformer. The expander oil level monitoring device comprises an upper limit switch, a lower limit switch, an upper indicator light, a lower indicator light and a power supply, wherein the upper limit switch can be triggered by a corrugated pipe of a corrugated pipe expander when the corrugated pipe moves upwards to the highest oil level, the lower limit switch can be triggered by the corrugated pipe of the expander when the corrugated pipe contracts downwards to the lowest oil level, the upper indicator light and the lower indicator light are controlled by the upper limit switch and the lower limit switch respectively to be turned on, and the power supply is used for supplying power to the upper indicator light and the lower indicator light. When the corrugated pipe of the expander moves upwards and reaches the highest oil level of a product, the upper limit switch is triggered to act, and the upper indicator light is turned on to remind a user that the oil level is high; when the corrugated pipe of the expander contracts downwards and reaches the lowest oil level of the product, the lower limit switch is triggered to act, and the lower indicator light is turned on to remind the user that the oil level is low and oil needs supplementing. In this way, the purpose of monitoring the oil level of the current transformer is achieved, the probability of occurrence of accidents caused by an over-high oil level or over-low oil level is reduced, and the safety of the current transformer is improved.
Description
Technical field
The utility model relates to high-tension electricity current measure device, particularly a kind of current transformer expander level monitoring device.
Background technology
High-tension current inductor is generally arranged on about two meters of high supports, the height of product is more than two meters, device whole height is higher, cause like this oil level of current transformer to be difficult to think observation, secondly, current transformer is after using several years, due to outdoor filth, cause oil level glass smudgy, oil level indication is also difficult to observe.And current transformer is long-time is prone to the problem of oil seepage after using, if can not monitor the timely supplementary insulation oil of oil level, can cause potential safety hazard to the safe operation of electric system, thus be necessary existing oil-immersed current transformer to be improved, to improve the performance of product.
Utility model content
The utility model object is to overcome the defect of prior art, provides a kind of oil level of monitoring to change, and improves the current transformer expander level monitoring device of current transformer security.
For achieving the above object, the utility model is by the following technical solutions:
A kind of current transformer expander level monitoring device, comprise the upper limit position switch that corrugated tube by bellow expander touches while moving up to the highest oil level, the lower position switch touching while being contracted to minimum oil level downwards by the corrugated tube of expander, by upper limit position switch and lower position switch, controlled respectively upper pilot lamp and the lower pilot lamp of lighting, and be the power supply of upper and lower pilot lamp power supply.
Described upper pilot lamp and lower pilot lamp lay respectively at bellow expander outer upper ends and lower end.
Described power supply is connected with lower pilot lamp with upper pilot lamp respectively by electric wire, is upper pilot lamp and the power supply of lower pilot lamp simultaneously.
Described upper limit position switch and lower position switch lay respectively at bellow expander outer upper ends and lower end.
Described upper pilot lamp and lower pilot lamp are light emitting diode.
Current transformer expander level monitoring device of the present utility model, when expander corrugated tube moves upward, while arriving the highest oil level of product, touches upper limit position switch action, switches on power, and upper pilot lamp is bright, and prompting user oil level is high; Carry out Oil drain operation.When expander corrugated tube shrinks downwards, while arriving the minimum oil level of product, touch lower position switch action, switch on power, lower pilot lamp is bright, and prompting user oil level is low, carries out repairing operation; By the flexible pilot lamp prompting oil level of lighting of corrugated tube, change, play the object of monitor current mutual inductor oil level, reduce because oil level is too low or the too high contingency occurrence probability causing, improve current transformer security.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model;
Fig. 2 is the structural representation of current transformer in the utility model;
In figure: the upper pilot lamp of 11-; Pilot lamp under 12-; 21-upper limit position switch; 22-lower position switch; 3-power supply; 4-electric wire; 5-bellow expander.
Embodiment
Below in conjunction with accompanying drawing, the utility model will be further described.
Referring to Fig. 1 and Fig. 2, current transformer expander level monitoring device, comprise the upper limit position switch 21 that corrugated tube by bellow expander 5 touches while moving up to the highest oil level, the lower position switch 22 touching while being contracted to minimum oil level downwards by the corrugated tube of expander, by upper limit position switch 21 and lower position switch 22, controlled respectively upper pilot lamp 11 and the lower pilot lamp 12 of lighting, upper pilot lamp 11 and upper limit position switch 21 are positioned at the upper end of bellow expander outside, lower pilot lamp 12 and lower position switch 22 are positioned at the lower end of bellow expander outside, power supply 3 is connected with lower pilot lamp 12 with upper pilot lamp 11 respectively by electric wire 4, be upper pilot lamp 11 and 12 power supplies of lower pilot lamp simultaneously, described upper pilot lamp and lower pilot lamp are light emitting diode.
On the expander of interiors of products, increase machine control unit, upper and lower travel switch and pilot lamp have been installed, expander corrugated tube move flexible in, after associated with upper and lower travel switch, start pilot lamp, current transformer internal transformer oil is with temperature generation volume change, the corrugated tube of expander stretches with the variation of transformer oil volume, when changing, corrugated tube touches upper and lower lead limit switch, after travel switch action, connect upper circuit, pilot lamp is bright, prompting oil level height, so that monitor staff operates in time accordingly, reduce the generation of mutual inductor accident.
