Abstract
The utility model discloses a portable protection device pilot lamp detects instrument, including the cage, be equipped with 5V battery jar, switch, small bulb and photo resistance that series connection is in proper order looped in in the cage, the photo resistance is the pilot lamp to being surveyed just. The beneficial effects of the utility model are that: 1, meet the strong weather of light and can't judge that the pilot lamp is bright and go out the time, cover portable protection device pilot lamp detects instrument outside the pilot lamp, transport the dimension personnel and can confirm the pilot lamp condition of going out of shining, 2, when pilot lamp luminance is more weak, also usable portable protection device pilot lamp detects instrument, photo resistance sensitivity is high, has enlargied pilot lamp luminance through small bulb is indirect, makes clear the pilot lamp condition.
Description
Technical field
The utility model belongs to pilot lamp testing tool, relates to a kind of Portable protection device pilot lamp testing tool particularly.
Background technology
Depend on the identification of operation maintenance personnel naked eyes at present and seal hand and observe.1, when light is strong, naked eyes cannot accurately judge.2, seal manual manipulation and need two hands, it is not convenient to operate.3, when pilot lamp light is weak, pilot lamp light on and off cannot be judged.
Utility model content
The purpose of this utility model overcomes deficiency of the prior art, provides a kind of rational in infrastructure, Portable protection device pilot lamp testing tool safely and effectively.
This Portable protection device pilot lamp testing tool, comprises cage, and in cage, be provided with the 5V battery case in series connection formation loop successively, switch, miniature bulb and photoresistance, described photoresistance is just to tested pilot lamp.
As preferably: described photoresistance is provided with inner photoresistance cover, and described inner photoresistance cover covers on tested pilot lamp.
The beneficial effects of the utility model are: when the weather that 1, chance light is strong cannot judge pilot lamp light on and off, cover on outside pilot lamp by Portable protection device pilot lamp testing tool, operation maintenance personnel can determine pilot lamp light on and off situation; 2, when pilot lamp brightness is more weak, also can utilize Portable protection device pilot lamp testing tool, photoresistance is highly sensitive, is indirectly exaggerated pilot lamp brightness by miniature bulb, specifies pilot lamp situation.
Accompanying drawing explanation
Fig. 1 is the utility model front view;
Fig. 2 is the utility model left view;
Fig. 3 is the attached view of the utility model;
Description of reference numerals: cage 1,5V battery case 2, switch 3, miniature bulb 4, photoresistance 5, inner photoresistance cover 6, electric wire 7.
Embodiment
Below in conjunction with drawings and Examples, the utility model is described further.Although the utility model will be described in conjunction with preferred embodiment, should know, not represent the utility model restriction in the described embodiment.On the contrary, the utility model will contain can be included in attached claims limit scope of the present utility model in alternative, modified and equivalent.
As shown in Figure 1 to Figure 3; this Portable protection device pilot lamp testing tool of the present embodiment; comprise cage 1, in cage 1, be provided with the 5V battery case 2 in series connection formation loop successively, switch 3, miniature bulb 4 and photoresistance 5, described photoresistance 5 is just to tested pilot lamp.Described photoresistance 5 is provided with inner photoresistance cover 6, and described inner photoresistance cover 6 covers on tested pilot lamp.
When operation maintenance personnel carries out protective device tour; when meeting high light weather or pilot light power; this Portable protection device pilot lamp testing tool is covered on pilot lamp; close a switch, if pilot lamp is bright, photoresistance 5 conducting can make miniature bulb 4 luminous; if pilot lamp goes out; photoresistance 5 is large, and miniature bulb 4 does not work, and operation maintenance personnel just can confirm pilot lamp instruction circuit deciliter situation.
Principle of the present utility model: due to fine day particularly summer, light was strong time and pilot lamp brightness more weak time; operation maintenance personnel often encounters the situation that protective device pilot lamp is difficult to recognize in substation inspection process, and Portable protection device pilot lamp testing tool can effectively address this problem.First cover on around pilot lamp by cage, effective isolating exterior light source, opens switch, if pilot lamp is bright, due to the effect of light, photoresistance 5 resistance diminishes, circuit turn-on, make extraneous miniature bulb 4 luminous, if pilot lamp goes out, then photoresistance 5 resistance is large, circuit breaker, miniature bulb 4 does not work, and add an inner photoresistance cover 6 again outside photoresistance 5 and guarantee that photoresistance 5 does not affect by external light source, the discussion of above two kinds of situations can realize the judgement of pilot lamp light on and off.
