Abstract
The utility model provides a short -term test circuit switches on device. It detects technical field to belong to the cable break -make. It is solved the exactness that adopts instrument and meter inspection wiring such as universal meter in current large project job site and circuit continuity test and has the problem that increases economic burden. Its leading features is: including dry battery box, loudspeaker, connecting wire and just, negative pole fastener, the dry battery box is anodal connects anodal fastener through the wire, dry battery box negative pole passes through the wire to be connected with the one end of loudspeaker, and the other end of loudspeaker passes through the wire and is connected with earth connection and negative pole fastener. The utility model has the characteristics of use simple structure, convenient to use, low cost, suitable job site, the exactness and the circuit continuity test of the wiring of mainly used large project construction field inspection.
Description
Technical field
The utility model belongs to cable break-make detection technique field, is specifically related to a kind of for the quick detection line of power industry debugging and maintenance, the device of equipment conducting.
Background technology
In electric power debugging, wiring, maintenance, a cable has many heart yearns, and special picture control cables even nearly more than 10, in wiring process, often easily mix up, two rear line heads can not be differentiated.In addition, need to check the correctness of wiring when debugging, maintenance, test whether conducting etc., all need a kind of device of quick detection, and the instrument and meters such as existing multimeter, expensive, and the quantity that large project executes man-hour requirement is more, virtually adds financial burden to company.
Summary of the invention
The purpose of this utility model is to provide the quick detection line conducting device that a kind of structure is simple, easy to use, with low cost, be applicable to working-yard use.
The utility model realizes the technical solution that above-mentioned purpose takes: a kind of detection line conducting device fast, is characterized in that: comprise dry cell batteries box, loudspeaker, connection wire and positive and negative electrode wire clamp; Dry cell batteries box positive pole connects positive pole wire clamp by wire; Dry cell batteries box negative pole is connected with one end of loudspeaker by wire, and the other end of loudspeaker is connected with ground wire and negative pole wire clamp by wire.
Loudspeaker described in the utility model technical solution are a compact horn, and dry cell batteries box is the power pack of in-built 6 joint 1.5V dry cells.
The utility model is owing to adopting by battery box, loudspeaker, connect wire and just, the quick detection line conducting device that negative pole wire clamp is formed, wherein, dry cell batteries box positive pole connects positive pole wire clamp by wire, dry cell batteries box negative pole is connected with one end of loudspeaker by wire, the other end of loudspeaker is connected with ground wire and negative pole wire clamp by wire, thus the correctness of wiring is checked in large project working-yard, when testing whether conducting, only need by one end ground connection of each heart yearn in cable, with the other end of each heart yearn in electrode line clamping connection cable, can judge according to the sound that loudspeaker send.Circuit in short-term, directly can be connected to the two ends of the utility model positive pole wire clamp, negative pole wire clamp, can judge according to sound.
The beneficial effects of the utility model are: the utility model solves on-the-spot wireline inspection conduction problem, improve the convenience of field maintemance work.
The utility model has the advantages that structure is simple, easy to use, with low cost, be applicable to working-yard use.The utility model is mainly used in correctness and the line conduction test that large project working-yard checks wiring.
Accompanying drawing explanation
Fig. 1 is device schematic diagram of the present utility model.
In figure: 1-dry cell batteries box, 2-loudspeaker, 3-wire, 4-wire clamp, the tested cable of 5-.
Embodiment
As shown in Figure 1.The quick detection line conducting device of the utility model comprises dry cell batteries box 1, loudspeaker 2, connects wire 3 and positive and negative electrode wire clamp 4.Dry cell batteries box 1 is the power pack of in-built 6 joint 1.5V dry cells.Dry cell batteries box 1 positive pole connects positive pole wire clamp 4 by wire 3, and positive pole wire clamp 4 is convenient to be connected with each heart yearn termination in tested cable.Dry cell batteries box 1 negative pole is connected with one end of loudspeaker 2 by wire 3, and the other end of loudspeaker 2 is connected with ground wire and negative pole wire clamp 4 by wire 3.Loudspeaker 2 are conventional compact horn.When positive pole wire clamp is connected with one end of tested cable 5, by the other end ground connection of tested cable 5, can judge according to the sound that loudspeaker 2 send.When positive pole wire clamp, negative line clamping connection are when the tested cable 5 of same conducting, loudspeaker 2 can be sounded; When obstructed, can not sound.
