Abstract
The utility model relates to a two-phase AC quartz fiber electroscope. A metal contact button is installed at the left end of an insulating pencil vase, two sets of neon bulbs and resistors are installed in the insulating pencil vase in parallel, and a metal pencil head and a measuring terminal are installed at the right end of the insulating pencil vase in parallel. The metal pencil head is electrically connected with the metal contact button after the metal pencil head is connected with the resistor R1 and the neon bulbs in series and in turn, and the measuring terminal is electrically connected with the metal contact button after the measuring terminal is connected with the resistor and the neon bulbs in series and in turn. When the utility model is used, the single-phase AC can be measured, the two-phase AC of a circuit can be detected simultaneously, the broken circuit fault of the circuit can be detected, and the fault point can be ascertained.
Description
The utility model relates to a kind of two cross streams electroscopes, can measure simultaneously two-phase alternating-current circuit.
Test pencil commonly used is be installed in series on the insulation pen container metal touching button, neon bulb, resistance and metal nib, and whether charged this test pencil only can carry out measurement, function singleness to single-phase circuit.
The purpose of this utility model is to propose a kind of two cross streams electroscopes, and this electroscope can not only be measured single-phase alternating current, the two-phase alternating current in the testing circuit simultaneously, but and the open circuit fault in the testing circuit.
The purpose of this utility model is achieved in that a kind of two cross streams electroscopes, left end at the insulation pen container is equipped with described metal touching button, two groups of neon bulbs and resistance are installed in the insulation pen container side by side, the right-hand member of insulation pen container is installed metal nib and measurement terminal side by side, the metal nib is connected successively with resistance R 1 and neon bulb and then is electrically connected with the metal touching button, and measurement terminal is connected successively with resistance R 2 and neon bulb and then is electrically connected with the metal touching button.When quarter-phase circuit being measured with the utility model, when the metal nib is touched A point in the circuit, when measurement terminal is touched B point in the circuit, though gauger's hand contacting metal touching button whether, when two neon bulbs of this electroscope are all bright.Just can determine that this circuit is a quarter-phase circuit.When gauger's hand contacting metal touching button, when the neon bulb of connecting with the metal nib was lighted, then the point of the B in the circuit was a bit on the zero line.When single-phase circuit was measured, when gauger's hand contacting metal touching button, two neon bulbs of this electroscope were all bright, and when gauger's hand not during the contacting metal touching button, two neon bulbs of this electroscope all do not work, and then this circuit is a single-phase circuit.When quarter-phase circuit breaks down, can use said method to measure piecemeal, just can find the trouble spot.
It is more that compared with the prior art the utility model has function, advantage easy to use.
The utility model is described in further detail below in conjunction with drawings and Examples.
Fig. 1, structural representation of the present utility model
Fig. 2, electrical schematic diagram of the present utility model
Two (Fig. 1 C point enlarged drawings) of Fig. 3, embodiment of the present utility model
Referring to accompanying drawing, the left end of the insulation pen container 4 of two cross streams electroscopes is equipped with described metal touching button 1, the insulation pen container is transparent plastic body, two groups of neon bulbs and resistance are installed in it side by side, the right-hand member of insulation pen container is installed metal nib 6 and measurement terminal 8 side by side, this measurement terminal is a metal clip, and the binding post that is embedded in the insulation pen container by lead 7 and notes is electrically connected, the metal nib is connected the back by sheet metal 3 successively with resistance R 1 and neon bulb 5, spring 2 is electrically connected with the metal touching button, measurement terminal with pass through sheet metal after resistance R 2 and neon bulb 5 are connected successively, spring is electrically connected with the metal touching button.For easy to use, install and measure terminal mount pad 9 side by side in right-hand member and the metal nib of insulation pen container, its internal thread connection measurement terminal plug 10, this plug is electrically connected with measurement terminal.When being used as common electroscope, can take off measuring plug and measurement terminal.
