Abstract

The invention belongs to the field of live detection of electrical equipment, particularly relates to a novel double-antenna electromagnetic wave acquisition device for detecting arc extinguishing characteristics of a circuit breaker, and discloses a double-antenna electromagnetic wave acquisition device for detecting arc extinguishing characteristics of a circuit breaker in electric power engineering. The device is characterized in that two ultrahigh-frequency sensors are simultaneously installed at positions right opposite to an arc extinguishing chamber of the circuit breaker, the two sensors are simultaneously connected with a data acquisition card through BNC cables, and the data acquisition card is connected with a computer through a double-end USB cable. The device is advantaged inthat two same electromagnetic wave signals can be collected, and reliability is higher compared with an original single signal; a problem that the single-antenna electromagnetic wave acquisition device cannot acquire effective and reliable radiation electromagnetic wave signals due to serious interference of on-site electromagnetic signals is effectively avoided; the two collected electromagneticwave signals can be compared on a computer, the test result is clearer, and the test conclusion is more reliable.

Description

technical field [0001] The invention belongs to the field of live detection of electrical equipment, and in particular relates to a novel dual-antenna electromagnetic wave acquisition device for detecting the arc-extinguishing characteristics of a circuit breaker, which is a dual-antenna electromagnetic wave acquisition device for detecting the arc-extinguishing characteristics of a circuit breaker in electric power engineering. Background technique [0002] High-voltage circuit breakers are widely used in practical power engineering. In power systems, high-voltage circuit breakers are not only an electrical component that breaks circuits, but also play a certain role in controlling the power system. It can cut off and connect the load circuit, and at the same time, it can cut off the circuit when a serious fault occurs, such as a serious short circuit fault, a serious voltage loss fault, etc., to ensure the normal operation of the non-faulty part of the power system. Theref...
