Abstract
The utility model discloses a grounding-type low-voltage electroprobe, which is specifically suitable for low-voltage electric detection in outdoor power grid maintenance work. The grounding-type low-voltage electroprobe comprises a test contact, a plastic shell, a neon tube, a resistor, a small spring, and a fastener. The grounding-type low-voltage electroprobe is characterized in that the tail end of the fastener is connected with an insulating soft copper wire, and the tail end of the insulating soft copper wire is connected with an insulating alligator clip. During the using process, a loop is formed by grounding through the insulating alligator clip, and whether equipment or lines are electrified or not is determined based on whether the neon tube gives out light or not. Moreover, multiple-point detection can be realized by one-time grounding of the insulating alligator clip; the efficiency is increased; and the outdoor power grid maintenance work is benefited. The grounding-type low-voltage electroprobe is safe and highly efficient, and is simple in structure, low in manufacture cost, low in price, convenient to use and carry, and easy to be accepted by the majority of users.
Description
Technical field
The utility model relates to a kind of grounding type low-voltage electroscope, is specially adapted to the electrical verification of outdoor electrical network maintenance activity low pressure.
Background technology
The low pressure electroscope is to judge live wire in lighting circuit and zero line, the whether charged common tool of check low voltage electrical equipment.Its profile is divided into pen type, screwdriver type and combined etc. multiple, is mainly for checking the whether charged a kind of specific purpose tool of low voltage electrical equipment and circuit.The metal penpoint of low pressure neon tube formula electroscope contacts with the single line in circuit, holds the metallic object part of a tail.If at this moment the neon tube in electroscope is luminous, that root line that metal penpoint contacts is exactly live wire, and another root is zero line.
At present, service worker is used common low-voltage electroscope when whether the check of outdoor electrical network maintenance low-voltage equipment has electricity, usually to stand on good (bamboo) ladder of insulation, adding the low pressure job requirements wears insulated shoes and also will wear cotton gloves, at this moment the pressure common electroscope is not because having the loop neon bulb will be not luminous or luminous very weak, especially outdoor, light becomes clear and is difficult for identification, and electric shock accidents especially easily occurs in operation without authorization.
The utility model content
Technical problem to be solved in the utility model is to provide a kind of low pressure electrical verification accuracy, grounding type low-voltage electroscope that reliability is high, has met the security requirement of low pressure electrical verification technical measures when outdoor low pressure electrical verification operation.
For solving the problems of the technologies described above, technical solution adopted in the utility model is: a kind of grounding type low-voltage electroscope, comprise test contact, plastic casing, neon tube, resistance, little spring and securing member, it is characterized in that: described securing member tail end connects an insulation annealed copper wire, and described insulation annealed copper wire tail end connects the insulation crocodile clip.
Described insulation annealed copper wire peripheral hardware insulating sheath.
Described insulation annealed copper wire and the welding of described securing member, its other end welds or is threaded with insulation crocodile clip tail end.
The beneficial effect that adopts technique scheme to produce is: grounding type low pressure electroscope of the present utility model is by connecting insulation annealed copper wire and insulation crocodile clip at the securing member tail end, in use by insulation crocodile clip and device housings, zero line or the idiostatic greatly temporary grounding utmost point connect, form loop, when checking low voltage electrical equipment and circuit whether charged, the neon bulb of low pressure electroscope is luminous normal, principle of work is clear, easy to use, cost of manufacture is low, except the accurate reliability that meets the low-voltage equipment electrical verification, can also search equipment failure for factory, electrical maintenance personnel hand-held electroscope easily carry out the checkout equipment fault, can judge very rapidly and accurately trouble spot, safe and efficient.
The accompanying drawing explanation
Below in conjunction with the drawings and specific embodiments, the utility model is described in further detail.
Fig. 1 is the structural representation of the utility model grounding type low pressure electroscope.
As shown in Figure 1: 1 plastic casing, 2 test contact, 3 resistance, 4 neon tubes, 5 little springs, 6 securing members, 7 insulation annealed copper wires, 8 insulation crocodile clips.
Embodiment
The low pressure of grounding type shown in Fig. 1 electroscope is by plastic casing 1, plastic casting test contact 2 in the enclosure, and securing member 6, insulation annealed copper wire 7, insulation crocodile clip 8 forms, and resistance 3 is equipped with in plastic casing 1 inside, neon tube 4, little spring 5; Set up insulation annealed copper wire 7 and insulation crocodile clip 8 on existing electroscope basis, after in use making insulation crocodile clip 8 ground connection, can utilize 2 pairs of device lines that break down of test contact progressively to be surveyed, if the shinny proof of neon tube 4 has electricity herein, if build-up of luminance not illustrate that fault is created in herein and the last time sensing point between, can detect rapidly fault and be got rid of.
The utility model is for existing electroscope, and it is by securing member 6 tail ends, setting up guiding device, when test contact 2 with after check point contacts, if there is voltage to exist, test contact 2, resistance 3, neon tube 4, little spring 5, securing member 6, insulation annealed copper wire 7 and insulation crocodile clip 8 form the conducting loop, thereby neon tube 4 is luminous, and insulation crocodile clip 8 ground connection can realize that multiple spot detects, raise the efficiency, be convenient at outdoor electrical network maintenance activity.
Grounding type low pressure electroscope of the present utility model is by connecting insulation annealed copper wire and insulation crocodile clip at the securing member tail end, in use by insulation crocodile clip and device housings, zero line or the idiostatic greatly temporary grounding utmost point connect, form loop, when checking low voltage electrical equipment and circuit whether charged, the neon bulb of low pressure electroscope is luminous normal, principle of work is clear, easy to use, cost of manufacture is low, except the accurate reliability that meets the low-voltage equipment electrical verification, can also search equipment failure for factory, electrical maintenance personnel hand-held electroscope easily carry out the checkout equipment fault, can judge very rapidly and accurately trouble spot, safe and efficient.
Because the utility model is simple in structure, easy to use, cost of manufacture is low, be specially adapted to the electrical verification of outdoor electrical network maintenance activity low pressure, this device carries also conveniently simultaneously, and the cheap users of being easy to accept, in addition can also precise and high efficiency detect the device line fault.
