Abstract
The utility model relates to a tool for detecting electrified states of electric equipment and wires, in particular to a multifunctional electrification detecting pen for maintenance of electric instruments and equipment. The technical scheme includes that the multifunctional electrification detecting pen comprises a screwdriver head (1), a pen body (2), a neon bulb (3), a square-wave driven passive electromagnetic buzzer (4), a conducting base (6), a current-limiting resistor (7), a diode (8) and a pressurizing spring (10), the screwdriver head is arranged at the end of the pen body and sequentially connected with the current-limiting resistor, the diode, the neon bulb, the square-wave driven passive electromagnetic buzzer and the pressurizing spring which are arranged inside the pen body, and the conducting base is disposed at the other end of the pen body. The multifunctional electrification detecting pen for maintenance of electric instruments and equipment has the advantages that on the basis of the existing illuminating electrification detecting function, an audible alarming function is integrated inside the pen body so as to eliminate hidden safety hazards, an LED miniature strong torch light is disposed on the rear side of the pen body to be integrated with the pen body for providing illumination, and the screwdriver head made of vanadium-chromium alloy materials with high strength and high torsion is adopted so as to meet rigidness and torsion requirements and prolong service life of the multifunctional electrification detecting pen.
Description
Affiliated technical field:
The utility model relates to a kind of instrument that detects electric equipment, circuit electriferous state, particularly the multi-functional electroscope of instrument electricity plant maintenance.
Background technology:
In instrument electricity equipment daily servicing process, electroscope is a kind of security tool commonly used of indispensability, and it is by the above voltage of 100V on the inner neon bulb luminous detection of the rear equipment, and the prompting personnel prevent electric shock accidents, supplementary means when simultaneously, also being instrument electricity equipment failure investigation.
At present, simple in structure, the function singleness of electroscopes all on the market, there is following some deficiency: in the ⑴ line service by day, because solar radiation, in the electroscope use, the inner neon bulb of rear is luminous very faint, especially faradic existence in the alternating current circuit, the maintenance personal is judged by accident the electriferous state of equipment and circuit, and potential safety hazard is very big.⑵ in the daily servicing, usually substituting small-bore screwdriver with electroscope uses, space of planes is narrow and small behind most of power distribution cabinet, two people's operations are very crowded during plant maintenance, people work, a human flashlight lighting, connection terminal on the connecting terminal block number does not see at all, make the mistake tear open, wiring, influence equipment failure investigation progress, restriction is produced.⑶ along with industrial expansion, the raising of instrument electric automation level, the widespread use of PLC control system, the input and output connecting terminal block connection terminal aperture of PLC controller is little, and structure is quite compact, in the daily servicing, usually substitute small-bore screwdriver with electroscope and use, still, electroscope edge of a knife material is softer at present, can not substitute small-bore screwdriver and frequently use, easy deformation is scrapped.
The utility model content:
The utility model purpose provides the multi-functional electroscope of a kind of instrument electricity plant maintenance, and is multiple functional, and accurately the electriferous state of judgment device and circuit substitutes small-bore flat mouthful of screwdriver, and long service life solves the problems referred to above that exist in the background technology.
The technical solution of the utility model is: the multi-functional electroscope of a kind of instrument electricity plant maintenance, comprise driver bit, a body, neon bulb, square wave drive passive electrical magnetic-type hummer, conductive seat, current-limiting resistance, diode, holddown spring, driver bit is arranged on the end of a body, be connected successively with a current-limiting resistance of body inside, diode, neon bulb, square wave drive passive electrical magnetic-type hummer, holddown spring, the other end of a body is provided with conductive seat.
Neon bulb and square wave drive passive electrical magnetic-type hummer front and back layout, electric in parallel in electroscope afterbody cavity.
The utility model also is provided with the miniature high light torch of LED, torch switch, is arranged on a body outside, and the tube head of the miniature high light torch of LED also is provided with button cell towards the driver bit direction, is the miniature high light torch power supply of LED.
Pen also is provided with pen card on one's body, is easy to carry the cutter head that driver bit Wei Fan Chrome alloy is made.
The beneficial effects of the utility model are: the 1. multi-functional electroscope of the utility model, on original luminous electroscope function basis, adopt passive electrical magnetic-type hummer, body inner integrated the audible alarm function, thoroughly having solved in the line service on daytime makes inner neon bulb luminous faint because of solar radiation, the maintenance personal has eliminated potential safety hazard to the electriferous state generation erroneous judgement problem of equipment and circuit.2. the multi-functional electroscope of the utility model, adopt integral structure, sidepiece and a body are integrated after one's death in pen with the miniature high light torch of LED, avoided in the line service at night, because of space of planes behind the power distribution cabinet narrow and small, the plant maintenance space is crowded, underlit make the mistake tear open, wiring, influence equipment failure and investigates the progress problem.3. the multi-functional electroscope of the utility model, the electrical verification end adopts high strength, high moment of torsion De Fan Chrome alloy material to be made into the flat mouthful driver bit of 2mm * 100mm, substituting small-bore screwdriver uses, solved because small-bore screwdriver carries inconvenience, the problem of losing easily, Fan Chrome alloy material is durable in use simultaneously, satisfies high-quality screwdriver stiffness and torsion requirement, improves serviceable life.
