AN APPARATUS FOR DETECTING A CURRENT AND A VOLTAGE INTERGRATED WITH PROBE AND THAT FO WIRELESS TRANSMITTER

摘要

A probe integrated current/voltage detecting device and a wireless transmitter are provided to facilitate installation, maintenance, and repair by removing a connection wire between a probe and a terminal. A probe integrated current/voltage detecting device and a wireless transmitter are comprise a coil part(200), a control part(210), an analog input interlock part(220), a DC power supply part(230), an A/D converter(240), a power managing part(250), a serial communications part(260), a memory part(280), RTC(Real Time Clock, 270), a display part(290), and a wireless communications part(300). The coil part is connected to a secondary side wire of a transformer, and measures a current flowed in the wire. The control part controls operation of a current/voltage measuring probe(100). The analog input interlock part converts an output of the current/voltage measured in the coil part into a DC. The DC power supply part converts an AC signal flowed in the coil part into a DC signal. The A/D converter converts an analog signal of the current/voltage of the wire into a digital signal. The power managing part controls a charging/discharging of a battery(330) formed in one side inside the probe. The serial communications part transmits the measured current/voltage. The memory part stores setting information and driving information for measuring the current/voltage. The RTC provides visual information required in operation of the probe. The display part distinguishes states of normal, abnormal, overload, and power failure of the probe. The wireless communications part transmits a signal to a terminal(310).
