Abstract
The utility model relates to a multipurpose electrometric device, composed of a shell, two testing contact heads, a resistor, a hand contact electrode, a neon tube, a lamp bulb, a diode, a converting switch and a lamp bulb elevating mechanism. Indicator lights with two different forms are used in a circuit simultaneously for detecting, so the utility model can quickly recognize the positions of the zero line and the fire line no matter when the electric power is supplied normally or the electric power in the zero line is cut off, can detect two different kinds of voltage of 220V and 380V, can be used for temporary lighting, and thus, has multifunction; the utility model has simple structure, accurate detection, and small size good for carrying.
Description
The normal charged or zero line powering-off state multi-purpose type electricity measurer of identification zero, live wire position down when the utility model relates to a kind of energy measurement 220V and two kinds of voltages of 380V.
The electricity measurer of Chu Shouing has test pencil and multimeter in the market, and the former can only survey 220V voltage, and can't to discern which root lead when zero line cuts off the power supply be zero line, thus the time when surveying zero live wire neon tube all bright; Though the different voltages in latter's energy survey time road, but when zero line cuts off the power supply, have only the veteran in the loop, to add reliable ground wire and can measure zero live wire, the layman is difficult to grasp, its also powerless (having only the on-load test) its price height simultaneously when causing false voltage in case run into loose contact, inconvenience is carried again.
The purpose of this utility model is the multi-purpose type electricity measurer that provides the pilot lamp (bulb and neon tube) of two kinds of forms of a kind of usefulness to detect in a circuit simultaneously in order to overcome above-mentioned deficiency, when realizing measuring fast, accurately, simply and easily in 220V or the 380V circuit normal power supply and zero line outage zero, the live wire position.
The utility model is achieved in that the multi-purpose type electricity measurer is by two test contact, resistance, hand touched electrode, diode, switch, two kinds of form pilot lamp (induction type pilot lamp-neon tube, direct measuring type pilot lamp-bulb), bulb elevating mechanism and shell composition.Its bulb elevating mechanism by renovate, rotating shaft, slider, slide plate constitute.In a circuit, detect simultaneously with two kinds of form pilot lamp.Its connected mode is that bulb one end links to each other with a contact of switch, the other end links to each other with a test contact, diode is connected between another contact and bulb of switch, resistance (R) be connected on a test contact and switch after neon tube is connected in the middle of, when swinging to a contact, switch can survey 220V voltage, when swinging to another contact by surveying 380V voltage after the diode step-down, with the bulb elevating mechanism bulb is risen to shell upper during work and judge with pilot bulb whether power supply is normal, promptly pilot lamp is bright when electricity, otherwise does not work.Pilot lamp is bright, and the lead of the also bright then black of neon tube contact overlap joint is a zero line, and the do not work lead of then red contact overlap joint of neon tube is a zero line.When zero line cut off the power supply, pilot lamp did not work, pull out in two test contact any one by the luminous variation of neon tube just can determine zero, the live wire position.
The utility model has the advantages that: can survey that two kinds of different voltages (220V, 380V) can make out zero when normal power supply especially zero line cuts off the power supply, the live wire position, it is simple in structure, be convenient to maintenance, failure judgement is quick, high efficiency, accurately, effect is directly perceived, the ordinary person just can operate, function many except that be used for surveying electric when time outside the bulb release housing can also be used for temporary lighting, cheap, volume is little, be easy to carry, bring convenience to the electrician not only that also to be suitable for family standby.
Below in conjunction with embodiment and accompanying drawing the utility model is further described

Fig. 3 the utility model bulb elevation and subsidence mechanical sketch
This multi-purpose type electricity measurer is by plastic casing (1) as shown in Figure 2, two test contact (A) (H), 2M Ω resistance (R), neon tube (LN), pilot bulb (L) (220V15W), diode (IN4007), switch (S) (KN01-102), renovate (2), rotating shaft (3), slider (4), slide plate (5), hand touched electrode (6), left cap (7), dividing plate (8) is formed, C point on bulb (L) the termination switch (S), another termination test contact (A), diode (D) is connected on switch (S) and goes up between b point and the bulb (L), all electric elements are placed on shell (1) (in wide * length * thick=5 * 7.5 * 2.4cm), and housing is divided into two spaces with dividing plate (8), the left side has side cover (7) to be open-type, leftward space is put two test contact (A, H) and line, other electric elements are placed on rightward space, have elongated slot (9) on shell (1) right flank, bulb (L) is fixed on slide plate (5) left surface, slide plate (5) right flank and slider (4) are fixing, slider (4) can be in elongated slot (9) on, lower slider, as shown in Figure 3 slide plate (5) upper end by rotating shaft (3) with renovate (2) the formation bulb elevating mechanism that links into an integrated entity, hand touched electrode (6) is placed on shell (1) bottom and links to each other with neon tube (LN), when when work as shown in Figure 2, upwards pushing away then along elongated slot (9) slider (4), slide plate (5) makes progress, renovate (2) around the shaft (3) rotate and upset opens meanwhile that bulb (L) rises to shell (1) top, when measuring 220V voltage, switch (S) is swung to the C point, switch (S) is swung to the b point when measuring 380V voltage, by diode (D) step-down to guarantee 220V, 15W pilot lamp (L) is not burnt out.Open left cap (7) and take out test contact (A.H), the right hand is held shell (1), directly to the positive hole, ellipse garden of opening of shell (1) in neon tube (LN) position, right hand small thumb contact hand gets an electric shock and reports (6), pilot bulb (L) is bright during (linking to each other with neon tube) normal power supply, determine that the zero line method is: the lead of black test contact overlap joint is a zero line if neon tube (LN) is bright, neon tube does not work then, and the lead of red test contact overlap joint is a zero line, when phase line was cut off the power supply, pilot bulb (L) and neon tube (LN) did not all work.When zero line cuts off the power supply, pilot bulb (L) does not work, and neon tube (LN) is bright, pull out red test contact (H) this moment, the change lead of red test contact (H) overlap joint that then pulls out of still bright or brightness is a zero line as neon tube (LN), is zero line as the do not work lead of black test contact (A) overlap joint that explanation end then pulls out of neon tube (LN).Its Changing Pattern sees Table 1.
