Abstract
The utility model relates to a kind of test pencil with self-test function; comprise test contact and connected insulated handle; the neon bulb and protective resistance and hand touched electrode of mutually connecting is provided with in insulated handle inner chamber; insulated handle end connects an annular groove; be provided with known power source and the cleaning device for clean test contact in annular groove, annular groove end connects an annular bonnet.The utility model structure is simple, easy to use, go out the dirt of test contact by cleaning device to prevent from it from forming insulation course affecting test result and whether to be damaged test pencil by known power source and test, improve the safe reliability of test pencil, ensured the personal safety of electric power personnel.
Description
Technical field
The utility model relates to a kind of electrician tool, is specifically related to a kind of test pencil with self-test function.
Background technology
In electrical repair process, staff judges whether charged usually with test pencil, but at present test pencil is not high as a kind of reliability of security tool: one, test contact or occupy dirt thus form insulation course under Long-Time Service, accurately can not judge that whether test point is charged; If two by this judgment device without electricity, easily judge by accident when not knowing whether test pencil damages, thus cause security incident.
Summary of the invention
For the problems referred to above, the utility model provides a kind of security performance high, can ensure the test pencil of the band self-test function of work about electric power person's safety.
For solving the problem; the technical scheme that the utility model is taked is: a kind of test pencil with self-test function; comprise test contact and connected insulated handle; the neon bulb and protective resistance and hand touched electrode of mutually connecting is provided with in insulated handle inner chamber; insulated handle end connects an annular groove; be provided with known power source and the cleaning device for clean test contact in annular groove, annular groove end connects an annular bonnet.Go out the dirt of test contact by cleaning device to prevent from it from forming insulation course affecting test result and whether to be damaged test pencil by known power source and test, add the safe reliability of test pencil, ensured the personal safety of electric power personnel.
Dirt for ease of wiping test contact prevents it from forming insulation course, and described cleaning device is sand paper.
The voltage of described known power source is adjustable by 70V to 220V, power supply from the starting voltage of neon bulb to full test voltage adjustable, not only test pencil can be checked whether to damage but also can prevent the excessive neon bulb of voltage from puncturing, harm personal safety.
For the ease of dismounting, described insulated handle and annular groove and annular groove are with annular bonnet and are threaded.Annular groove can be backed out during test, thumb contact hand touched electrode is tested, if neon bulb does not all send aura when detecting each test point, then need to turn on annular bonnet, whether the test pencil taking out sand paper and known power source detection zone self-test function damages, if be connected to known power source still do not send aura, then prove that test pencil damages.
The utility model structure is simple, easy to use, go out the dirt of test contact by cleaning device to prevent from it from forming insulation course affecting test result and whether to be damaged test pencil by known power source and test, improve test pencil and starve safe reliability, ensured the personal safety of electric power personnel.
