Problems solved by technology

The voltage amplitude of the signal source used in this method is at the highest level of hundreds of V, and the volume is relatively large. Compared with the GTEM cell, the on-site real GIS will cause greater attenuation of the signal, so this signal source cannot be used
On the other hand, although this method can obtain the theoretical equivalent height of the sensor, it cannot obtain the measurement sensitivity when the electromagnetic propagation environment is a true GIS, that is, it cannot carry out the calibration work under the actual working conditions on site.

Description

technical field [0001] The invention belongs to the technical field of calibrating partial discharge sensors of gas-insulated and enclosed combined appliances (GIS), in particular to a fast pulse generating device for calibrating partial discharge sensors, in particular to a portable fast pulse generating device and a manufacturing method thereof. Background technique [0002] Partial discharge is the most important and effective method for evaluating the insulation state of gas-insulated combined electrical equipment (GIS). When partial discharge occurs in GIS equipment, signals such as light, sound, mechanical vibration and electromagnetic waves will be generated. The current partial discharge detection technology carries out corresponding research work around the above characteristic parameters. The pulse current method given by IEC-60270 is one of the most widely used detection methods at this stage, but the bandwidth of its detection equipment is tens to several thousa...
