Description

Voltage detecting method and voltage detecting device using the same

The present invention mainly discloses a voltage detecting method, in particular, a voltage detecting method that utilizes the principle of electromagnetic induction to achieve a safe detection of a high voltage electric voltage.

The most commonly used voltage detection method is to use a three-meter electric meter for detecting, and the three-meter electric meter is detected by connecting two pins to both ends of a circuit loop in the operation of the electric appliance to be tested, so that it can be obtained. The voltage consumed by the appliance to be tested. The operating principle when measuring the voltage with a three-meter is to use a galvanometer to connect a resistor with a high resistance value. When the two pins of the three-meter are connected to the two ends of the device to be tested, they can form with the electric appliance. In parallel, the current flowing through the galvanometer is reduced by the resistance at the high resistance, and the voltage measured by multiplying the current measured by the galvanometer by the resistance of the series resistor is obtained.

However, when the three-meter meter is used to measure the voltage, the range is not high, so that the three-meter meter is only suitable for non-high-voltage electricity, and it is impossible to measure the voltage exceeding 1000 volts.

Moreover, when the three-meter is connected to both ends of the circuit of the electrical circuit to be tested, the three-meter also forms a part of the circuit loop, and the current in the circuit flows into the three-meter, and the original circuit is dispersed. The current in the loop affects the operation of the appliance under test, making the three-meter meter unable to perform long-term continuous measurement.

Furthermore, the three-meter meter must be connected to the circuit loop during the operation of the circuit loop during use. During the connection process, the conductive part is exposed, if the user is in the process of connecting. Improper operation may result in leakage or even the risk of electric shock to the user.
