Overview of Q96-RZC Q72-RZC Q144-RZC Ammeter AC

AC ammeter refers to the ammeter embedded in the power equipment installed on ships or other occasions and measuring the rated working frequency of 50Hz and 60Hz.

Ammeter refers to the instrument used to measure the current in AC and DC circuits. In the circuit diagram, the symbol of ammeter is "circle a". The current value takes "a" or "a" as the standard unit.

The ammeter is made according to the action of magnetic field force on the energized conductor in the magnetic field. There is a permanent magnet inside the ammeter, which generates a magnetic field between the poles. There is a coil in the magnetic field. There is a hairspring at both ends of the coil. Each spring is connected to a terminal of the ammeter. Between the spring and the coil, it is connected by a rotating shaft, and there is a pointer at the front end of the rotating shaft relative to the ammeter. When a current passes through, the current passes through the magnetic field along the spring and rotating shaft, and the current cuts the magnetic induction line. Therefore, under the action of the magnetic field force, the coil deflects and drives the rotating shaft and pointer to deflect. Since the magnitude of the magnetic field force increases with the increase of the current, the magnitude of the current can be observed through the deflection degree of the pointer. This is called magnetoelectric ammeter, which is the kind we usually use in the laboratory. In junior high school, the range of ammeter used is generally 0 ~ 0.6A and 0 ~ 3a

The ammeter is made according to the action of magnetic field force on the energized conductor in the magnetic field. There is a permanent magnet inside the ammeter, which generates a magnetic field between the poles. There is a coil in the magnetic field. There is a hairspring at both ends of the coil.

Features of Q96-RZC Q72-RZC Q144-RZC Ammeter AC

1. The AC ammeter shall be connected in series with the electric appliance in the circuit (otherwise, the ammeter will be burned due to short circuit).

2. The measured current shall not exceed the range of the ammeter (the method of touch test can be used to see whether it exceeds the range).

3. The current should enter from the "+" terminal and exit from the "-" terminal (otherwise, the needle will be easily bent if the pointer is reversed).

4. It is not allowed to connect the ammeter to the two poles of the power supply without passing through the electrical appliance (the internal resistance of the ammeter is very small, which is equivalent to a wire. If the ammeter is connected to the two poles of the power supply, the pointer will be crooked, or the ammeter, power supply and wire will be burned out).
