Abstract

The utility model discloses a novel electroscope. Two metal probes are connected to one end of a light emitting diode and one end of a current-limiting resistor respectively and fixed in an insulating shell, wherein the light emitting diode and the current-limiting resistor are connected in series, and the metal probes extend out from an end portion of the shell. The novel electroscope has the advantages of simple structure, low manufacturing cost, convenient operation, easy carrying, stability and reliability. Furthermore, the luminance performance of the novel electroscope is superior to that of an ordinary electroscope neon indicator when detecting an electriferous object. There is no need to form a loop by a human body and the ground when detecting electricity by using the novel electroscope. In addition, the novel electroscope is capable of detecting a live line and a zero line simultaneously, thereby improving the safety and accuracy of electricity detection, improving judging speed of faults in electricity utilization. Therefore, a high precision instrument is not needed, thereby reducing the cost of detecting instruments.

Description

A kind of novel electroscope
Technical field
The utility model relates to electrician's testing tool, relates to a kind of electroscope in particular.
Background technology
At present; The single-phase bipolar low-voltage air switch be widely used in that industrial civilian low-voltage power panel box, dwelling house and business premises are concentrated and branchs family panel box in, wall is slotting, insert and movable multipurpose power source, conversion socket etc. also number of applications in various household electricities and industrial and agricultural production electricity consumption.
When above-mentioned parts operation irregularity we whether often lean on common low pressure electroscope to test live wire charged, existing electroscope mainly is made up of parts such as working contact, dropping resistor, neon bulb, springs.It is to utilize electric current to pass through electroscope, human body, the earth formation loop for this electroscope; Its leakage current make the neon bulb build-up of luminance luminous and work; But neon tube is the easily gas leakage and losing efficacy of an inflation glass tube, and electric power safety working regulation regulation is before the electrical verification; Should be earlier make an experiment having on the electric equipment, the conclusive evidence electroscope is good.When using test pencil, also must touch the metal section and part of test pencil tail end with hand, nib metal probe contact electrification equipment; Otherwise because of electrified body, test pencil, human body and the earth do not form the loop; Neon bulb in the test pencil can be not luminous, causes erroneous judgement, thinks that electrified body is not charged.So for safety, stipulate that wet hand can not go electrical verification, this all is very to bother to installing and keeping in repair.
We know that it is to lean on the observation neon bulb with zero line that electroscope is distinguished phase line in addition, and what neon bulb was shinny is phase line, and what do not work possibly be zero line, but work as zero line break and just often neon bulb is not shinny, so common electroscope can not accurately be concluded the zero line duty.Can only judge that multimeter is many gears multirange precision instrument this moment by multimeter, and the high volume of price carries inconvenience greatly, operates also more complicated.
The utility model content
The utility model technical matters to be solved is to realize a kind of two probe electroscopes easy to use.
To achieve these goals; The technical scheme that the utility model adopts is: a kind of novel electroscope; Two metal probes of electroscope connect the light emitting diode and the current-limiting resistance two ends of series connection and are fixed in the insulation shell, and described metal probe is stretched out by shell end.
Described housing is column, and the one of which end is provided with the metal probe other end and is provided with light emitting diode.
Two described metal probes are parallel to each other, and on spacing and the single-phase bipolar air switch pile crown or down two binding posts of pile crown between left and right apart from identical, also insert with wall, insert and movable multipurpose power source conversion socket in two socket spacings match.
Described current-limiting resistance resistance is 100K-120K Ω.
The advantage of the utility model is that novel electroscope is simple in structure, and low cost of manufacture is easy to use, is easy to carry about with one, and is reliable and stable, and test when electricity is arranged luminosity be superior to common electroscope neon tube indication; Do not need human body and the earth to form the loop when using this electroscope electrical verification; And detect live wire and zero line simultaneously, improved electrical verification process safe property and accuracy, improved electricity consumption failure judgment speed; Therefore do not use high precision instrument, reduce measuring instrument cost input.
Description of drawings
Face the content of every width of cloth accompanying drawing expression in the utility model instructions and the mark among the figure down and make brief description:
Fig. 1 is the electroscope structural representation;
Fig. 2 is the electroscope circuit diagram;
Mark among the above-mentioned figure is: 1, housing; 2, metal probe; 3, light emitting diode; 4, current-limiting resistance.
Embodiment
Can know referring to Fig. 1,2; The light emitting diode 3 of series connection is connected two metal probes 2 of electroscope respectively with current-limiting resistance 4 two ends; Electroscope is provided with column insulation shell 1, and foregoing circuit is fixed in the housing 1, and wherein two metal probes 2 are held capable stretching out level with both hands by housing 1 one; Housing 1 other end is fixed with light emitting diode 3, checks from the end whether equipment is charged thereby make things convenient for when using the electroscope electrical verification.Light emitting diode 3 can be selected the redness pipe of diameter 5 millimeter, requires WV 1.8~2.7V, working current 2~20mA, and current-limiting resistance 4 resistances are selected 100K-120K Ω, and power selects more than the 1/2W.
Two metal probe 2 spacings just in time with the single-phase bipolar air switch on pile crown or down two binding posts of pile crown between left and right apart from identical; Also insert with wall, insert and movable multipurpose power source conversion socket in two socket spacings match, do not need human body and the earth formation loop during electrical verification, so during with the electrical verification of this electroscope; Not requiring that the operator points keeps dry; Operation is very simple, when therefore using this electroscope, with metal probe 2 insert on the bipolar air switch pile crown or down in two binding posts of pile crown or two sockets electrical verification get final product; This moment, voltage signal arrived another metal probe 2 through a metal probe 2, light emitting diode 3, current-limiting resistance 4; If equipment under test Live line Zero line normal power supply, testing circuit forms the closed-loop path through outside line, makes light emitting diode 3 luminous; Any side's abnormal electrical power supply of Live line Zero line, then light emitting diode does not have indication.
Combine accompanying drawing that the present invention has been carried out exemplary description above; Obviously the concrete realization of the utility model does not receive the restriction of aforesaid way; As long as adopted the improvement of the various unsubstantialities that method of the present invention design and technical scheme carry out; Or design of the present invention and technical scheme are directly applied to other occasion without improving, all within the protection domain of the utility model.
