Abstract
The utility model relates to an electric test tool, which is composed of two electric test pencils and a metallic joint piece. The metallic tail ends of the two electric test pencils are mutually connected by metallic joint pieces, so that the circuit between the two test pencils can be mutually communicated. The electric test tool can be used for electric power construction and line maintenance. Besides the functions of common electric test tool, the utility model has the functions of testing whether an earth wire is in good condition, identifying whether a fuse is blown and differentiating line voltage from phase voltage.
Description
The electricity measurer whether electricity measurer, particularly test voltage exist.
At present, the electricity measurer that uses in power construction is a test pencil as shown in Figure 1.Whether this test pencil can have voltage by test lead, but the function singleness of this test pencil, and particularly when ground wire broke down, this test pencil can not judge whether ground wire is intact.When the fusing insurance of a circuit was fused, this test pencil can not be judged the failure cause that the fusing insurance is fused.This test pencil can not be differentiated phase voltage and line voltage on the power electricity transfer line of three-phase four-wire system.Because this test pencil can not finish above-mentioned function, for power construction and fault diagnosis are brought difficulty.
The objective of the invention is to design the electricity measurer whether a kind of electricity measurer, particularly test voltage exist, this electricity measurer has fault diagnosis functions, uses flexibly, and is simple in structure, is convenient to use in the power construction.
The method that realizes electricity measurer of the present invention is to adopt metal connecting piece (12) that the metal tail end (11,13) of two test pencils (18,19) is interconnected.
On the metal tail end (11,13) of test pencil (18,19) the metal joint pin (20,24) that is connecting metal connecting rod (21,23) can be installed, metal connecting rod (21,23) can connect by flexibly connecting knot (22).Test pencil (18, the 19) mast axis (25,27) on its metal tail end (11,13) respectively rotates, and metal connecting rod (21,23) can rotate around the axis (26) that flexibly connects knot (22).
Can there be the oat tail groove structure (28,29) of pairing mutually can dock two test pencils (18,19) on the test pencil (18,19) by oat tail groove structure (28,29), test pencil (18,19) can slide after docking by dovetail groove relatively, another test pencil is in the position after leaning on when making a test pencil job, like this, the test pencil in back neither influences the work of the test pencil in front, and a test pencil is carried out the moment that increase turns when turning operation in front again.
Realize that electric principle of the present invention is to utilize conductor that the metal tail end of two test pencils of electricity measurer is interconnected, the circuit series connection of two test pencils is connected.
Use electricity measurer of the present invention to judge when whether solid conductor has voltage, can use the test pencil (18) of electricity measurer or (19) and the repetition measurement examination is carried out in another test pencil (18) or (19), increase the reliability of test.
When using electricity measurer of the present invention to judge the ground wire fault, at first to measure live wire voltage is arranged, contact (7,17) with two test pencils (18,19) of electricity measurer contacts live wire and ground wire simultaneously respectively again, operating personnel's hand does not contact the metal tail end (11,13) and the bonding conductor thereof of test pencil (18,19), when pilot lamp (9,15) is bright, expression ground wire non-fault, pilot lamp (9,15) be not when working, and the expression ground wire is opened a way.
Use electricity measurer of the present invention to judge when the reason that is fused is insured in the fusing of circuit, the contact (7,17) of test pencil (18,19) can be contacted the insurance two ends that fused simultaneously respectively, operating personnel's hand does not contact the metal tail end (11,13) of test pencil (18,19) and is communicated with conductor.When the pilot lamp of test pencil (9,15) was bright, expression load end circuit had short trouble or serious overload.
When using electricity measurer of the present invention to judge the phase voltage of power transmission line of three-phase four-wire system and line voltage, the contact (7,17) of test pencil (18,19) can be contacted simultaneously any two lines in four leads respectively, when pilot lamp (9,15) is bright, the voltage that expression is surveyed is line voltage, display lamp (9,15) is luminous when dark, and the expression voltage of surveying is phase voltage.

The structure of the test pencil that uses as shown in Figure 1 at present.It is by contact (1), resistance (2), and pilot lamp (3), spring (4), metal tail end (5) is composed in series.When contact (1) the contact electrification lead of test pencil, when operating personnel contacted its metal tail end (6), pilot lamp (4) can be luminous.
Fig. 2 is the structural drawing of electricity measurer of the present invention.It is made up of two test pencils (18,19), and two test pencils (18,19) are respectively by contact (7,17), resistance (8,16) pilot lamp (9,15), and spring (10,14), metal tail end (11,13) series connection is connected into.The metal tail end (11,13) of two test pencils (18,19) is interconnected by metal connecting piece (12).Distance between the contact (7,17) of two test pencils (18,19) can change, in order to the different wire pitch of adaptive testing.
Fig. 3 is an embodiment of electricity measurer of the present invention.The metal joint pin (20,24) that connects metal connecting rod (21,23) is installed on the metal tail end (11,13) of two test pencils (18,19), metal connecting rod (21,23) connects by flexibly connecting knot (22), metal connecting rod (21,23) can rotate around the axis (26) that flexibly connects knot (22), and test pencil (18, the 19) mast axis (25,27) on its metal tail end (11,13) respectively rotates.
