    Description

    AC overload ammeter 45L1-A1 is embedded in a ship or other occasion power equipment installation, and measures AC voltage with a rated operating frequency of 50Hz and 60Hz, and a wide-angle AC current meter.

    The AC current meter mainly adopts the measurement mechanism of the electromagnetic system electric meter, the electric system electric meter and the rectifier type electric meter. The lowest range of the electromagnetic measuring mechanism is about tens of milliamps. In order to increase the range, it is necessary to reduce the number of coil turns and thicken the wire. When an electric current measuring mechanism is used to form an ammeter, the moving coil and the static coil are connected in parallel, and the lowest range is about several tens of milliamps. In order to increase the range, if you want to reduce the number of turns of the static coil and thicken the wires, or change the two static coils from series to parallel, the range of the ammeter will be doubled. When using a rectifier meter to measure AC current, the ammeter reading is correct only when the AC has a sinusoidal waveform. A shunt can also be used to increase the range. In addition, high-frequency currents can also be measured with thermoelectric meter measurement mechanisms. The large-range AC ammeters used in power systems are mostly 5A or 1A electromagnetic system ammeters, and are equipped with current transformers with appropriate current conversion ratios.
    1. Uses:
    Embeddedly installed on ships, locomotives, power stations, mines, metallurgy, petrochemicals or other mobile power equipment, measuring AC current voltages with rated operating frequencies of 50, 400, and 427 Hz.
    2. Main technical performance:
    Class 2.5, splash proof and vibration resistant.
    3. Conditions of use:
    Ambient temperature: -25 ~ + 55 ℃, relative temperature: <98% RH
