Description

Novel electricity meter

Technical Field

The utility model relates to the technical field of instruments, specifically a novel ammeter.

Background

The ammeter is a meter used for measuring current in an alternating current circuit and a direct current circuit. In the circuit diagram, the symbol of the ammeter is "circle a". The current value is in standard units of "ampere" or "a". The ammeter is made by the action of magnetic field force applied to the current conductor in the magnetic field. The ammeter is internally provided with a permanent magnet, a magnetic field is generated between poles, a coil is arranged in the magnetic field, two ends of the coil are respectively provided with a balance spring, the springs are respectively connected with a connecting clamp of the ammeter, the springs and the coil are connected through a rotating shaft, and the front end of the rotating shaft, which is opposite to the ammeter, is provided with a pointer. When current flows, the current passes through the magnetic field along the spring and the rotating shaft, and the current cuts the magnetic induction line, so that the coil deflects under the action of the magnetic field force to drive the rotating shaft and the pointer to deflect. Since the magnitude of the magnetic field force increases with increasing current, the magnitude of the current can be observed by the degree of deflection of the pointer.

A voltmeter is an instrument for measuring voltage, and is commonly used in electric meters — the voltmeter symbol: v, a permanent magnet is arranged in the sensitive ammeter, a coil formed by a lead is connected in series between two jointing clamps of the ammeter, and the coil is placed in the magnetic field of the permanent magnet and is connected with a pointer of the meter through a transmission device. Most voltmeters are divided into two ranges. The voltmeter is provided with three jointing clamps, a negative jointing clamp and two positive jointing clamps, wherein the positive pole of the voltmeter is connected with the positive pole of the circuit, and the negative pole of the voltmeter is connected with the negative pole of the circuit. The voltmeter must be connected in parallel with the electrical appliance to be tested. The voltmeter is a fairly large resistor, ideally considered as an open circuit. The range of the voltmeter commonly used in the junior middle school stage laboratory is 0-3V and 0-15V. The traditional pointer type electric meter comprises a sensitive ammeter, a permanent magnet is arranged in the sensitive ammeter, a coil formed by a conducting wire is connected between two wiring clamps of the ammeter in series, and the coil is placed in a magnetic field of the permanent magnet and is connected with a pointer of the meter through a transmission device. Most electricity meters are divided into two ranges. The voltmeter is provided with three jointing clamps, a negative jointing clamp and two positive jointing clamps, wherein the positive pole of the ammeter is connected with the positive pole of the circuit, and the negative pole of the ammeter is connected with the negative pole of the circuit.

Current and voltage are basic quantities in electricity, a current meter and an electricity meter are basically divided into two types, namely a pointer type meter and a digital type meter, and the pointer type electricity meter is a traditional meter and is applied to various departments. The pointer type electric meter consists of a shell, a dial, a magnet, a coil and a pointer. The magnitude of the current passing through the coil is represented by the magnitude of the angle of rotation of the coil mounted in the magnet, and the voltage value is represented by the product of the current passing through the coil and the resistance connected in series with the electricity meter line. Traditional pointer-type ammeter base and casing volume are great, and the panel board can not remove, and the user reading is inconvenient when using the ammeter.
