Abstract

The utility model relates to an electricity tester which can replace a universal meter to use, mainly comprising a circuit which is compose of neon bulbs L1, L2, and L3 and a resistor R4, in order to measure the high and low of the voltage. After light emitting diodes LED2 and LED3 are connected with a resistor R5 in series, the light emitting diodes LED2 and LED3 are jointed in parallel on both ends of the circuit. According to the light emitting situations of the light emitting diodes LED2 and LED3, the A. C. and the D. C. are measured. Triodes BT1, BT2, and BT3 are directly coupled in sequence to constitute a composite pipe. A light emitting diode LED2 is jointed in series between the triode BT3 and the positive pole of a battery E. The negative pole of the battery E is jointed between the emitting pole of the triode BT3 and a resistor R1. The circuit on the part can measure the on-off of the circuit. The utility model has the advantages of simple structure, low cost, convenient use and maintenance, etc.

Description

Multi-function electricity tester

The utility model is a kind of Multifunction electricity measurer.

The multi-functional electricity measurer of the utility model is a kind of maintenance tool.

Existing multi-functional electroprobe function is few, complex structure.As the multifunction test pencil of announcing on the novel communique of practicality, notification number CN2071342U has adopted the electronic circuit replacing neon bulb to show complex structure, cost height.Notification number CN207679U multifunction test pencil, gear is too much, and is also unreliable, and ceiling voltage can only be surveyed 260V, so and the present supply voltage of China mostly is 110V, 220V, 380V is not welcome by numerous electricians.

The purpose of this utility model is to provide a kind of multi-functional electricity measurer, and it can easily measure whether phase shortage of 110V, 220V, 380V distribution voltage, has alternating current-direct current simultaneously and shows, energy measurement electric wire, coil break-make, logical circuit, two, the PN junction of triode.

The technical solution of the utility model is:

A kind of multi-functional electricity measurer, main probe A, secondary probe B connects by insulated conductor, it is characterized in that: being used to install on the bar shell of main probe A has the LED of appearing 1, LED2, LED3 and neon bulb L1, L2, the position, hole of L3, above-mentioned neon bulb L1, L2, L3 and resistance R 4 connect successively, neon bulb L2 wherein, the two ends of L3 are parallel with resistance R 2 and R3 respectively, neon bulb L1 is connected with main probe A, resistance R 4 is connected with secondary probe B, the LED 2 that polarity is opposite and in parallel, LED3 be connected in parallel on neon bulb L1 after resistance R 5 is connected, L2, L3 and resistance R 2, R3, the circuit two ends that R4 constitutes, BT1, BT2, BT3 forms complex pipe series connection R1 and also is connected in parallel on neon bulb L1, L2, L3 and resistance R 2, R3, the circuit two ends that R4 constitutes, LED 1 is connected between BT3 emitter and the battery E positive pole, and battery E negative pole is connected between BT3 collector and the resistance R 1.

The multi-functional electricity measurer of the utility model is compared with existing electroprobe, and it is many to have function, simple in structure, dependable performance, advantage such as easy to maintenance.

Below in conjunction with accompanying drawing the utility model is further described.

Two ends metal part branch with main probe A and secondary probe B contacts tested electrode two ends, differentiate tested voltage by the bright number of neon bulb, the bright demonstration of neon bulb L1 110V power supply is normal, L1, L2 two neon bulbs are simultaneously bright, show that the 220V power supply is normal, L1, L2, three neon bulbs of L3 are simultaneously bright, show that the 380V power supply is normal, LED 2, LED3 are simultaneously bright, show that tested voltage is alternating current.LED2, LED3 have only one bright, show that tested voltage is direct current.

The most advanced and sophisticated metal part of main probe A and secondary probe B is contacted tested wire or coil two ends, LED 1 bright demonstration tested wire or coil path respectively.LED1 does not work and shows that then electric wire or coil open circuit.Whether Measuring Object charged two kinds of methods: the one, with main probe A contact electrification object, secondary probe B is unsettled need not, LED1 is bright to show that then testee is charged, LED1 does not work, and then testee is not charged, the 2nd, with the insulating outer layer of main probe A contact electrification object, secondary probe B contact ground wire or center line, LED1 is bright to show that then object is charged, LED1 does not work and shows that then testee is not charged.

The multi-functional electricity measurer of the utility model is particularly useful for vast factory, and machine-operated electrician uses, and also can use for broad masses.

The multi-functional electricity measurer shell of the utility model can for ease of carrying, keep in repair with the method for injection mo(u)lding, and main probe A shell is injection molded into two hemizygotes, and secondary probe B is placed on main probe A enclosure interior.
