Abstract
The utility model discloses a low voltage electroscope which includes an insulating body, a detection circuit which is arranged in the insulating body, a metal screw which is arranged on the left end of the insulating body and is connected with the output terminal of the detection circuit, an insulating sleeve which is arranged on the right end of the insulating body, and a testing pen which is arranged in the insulating sleeve. The left end of the testing pen is connected with the input terminal of the detection circuit. The detection circuit is composed of a first neon tube, a second neon tube, and a resistor. A switch includes an insulating button and a metal sheet. The first neon tube and the second neon tube are arranged in the insulating body, and a branch of the second neon tube is provided with the switch, so when the electroscope is used frequently and the first neon tube has a fault, the insulating button can be pressed down, the second neon tube works, and the detection circuit in the insulating body returns to normal, and the electroscope can work normally, and the service lifetime of the electroscope is greatly prolonged.
Description
Technical field
The utility model relates to a kind of low pressure electrical verification instrument, is specifically related to a kind of low pressure electroscope.
Background technology
The low pressure electroscope is mainly by probe, resistance.The parts such as neon tube and spring form, when whether checkout equipment is charged, electric current will be successively forms the loop by the working contact of electroscope, dropping resistor, neon tube and human body, there is weak current just can make neon tube luminous and electroscope is indicated, but because the work about electric power personnel can often use electroscope, can have a strong impact on the serviceable life of neon tube, thereby affect the serviceable life of electroscope.
Summary of the invention
Technical problem to be solved in the utility model provides a kind of low pressure electroscope that improves the serviceable life of electroscope.
The utility model is achieved through the following technical solutions: a kind of low pressure electroscope, comprise an insulation body, and be installed in the testing circuit of insulation in the body, and the metallic screw and the metallic screw that are installed in an insulation body left end link to each other with the testing circuit output terminal, and be installed in the insulation body right-hand member the insulating bar cover, and be arranged on the interior probe pen of insulating bar cover, and described probe pen left end links to each other with the testing circuit input end, and described testing circuit is comprised of the first neon tube, the second neon tube and resistance.
As preferably, described the first neon tube and the second neon tube are in parallel, and described the first neon tube and the second neon tube are connected with resistance.
As preferably, also be provided with switch on the branch road at described the second neon tube place.
As preferably, described switch comprises insulation button and sheet metal.
The beneficial effects of the utility model are: by being arranged on the first neon tube and the second neon tube in the insulation body, wherein be provided with switch on the branch road at the second neon tube place, when frequent use electroscope causes the first neon tube to break down, can press insulation button, the second neon tube is started working, make the testing circuit in the insulation body recover normal, electroscope can use as usual, can greatly improve like this serviceable life of electroscope.
Description of drawings
In order to be easy to explanation, the utility model is done to describe in detail by following specific embodiment and accompanying drawing.
Fig. 1 is the structural representation of a kind of low pressure electroscope of the present utility model.
