Abstract

The invention provides a simulator for partial discharge modes. The simulator comprises a partial discharge mode generator and a power amplification circuit; the partial discharge mode generator is connected with the input end of the power amplification circuit, and is used for storing various partial discharge modes recorded in advance, and when a selection instruction sent out to any partial discharge mode by a user is acquired, a partial discharge signal in a selected partial discharge mode is converted into a simulation signal for output; the output end of the power amplification circuit is connected with a distribution cable, and is used for acquiring the simulation signal, and after being amplified, the simulation signal is output as an electromagnetic wave, and is propagated along the distribution cable. By implementing the simulator provided by the invention, the partial discharge mode of any position in the distribution cable can be simulated for partial discharge monitoring equipment to be measured and analyzed; the simulator has the characteristics of being safe, portable and easy in operation; difficulties existing in the aspects of influence factor evaluation, product assessment, field application, personnel relevant skill training and the like in application practice are solved.

Description

technical field

[0001] The invention relates to the technical field of power distribution cable state monitoring, in particular to a partial discharge mode simulation device. Background technique

[0002] Distribution cables are used to transmit electric energy in the power system, and their safe operation has a major impact on the reliability of the distribution network of the power system. The monitoring of the operating status has become the focus of daily work, and the monitoring of the insulation status is the focus of the monitoring of the operating status of distribution cables.

[0003] At present, the insulation state monitoring technology of distribution cables is divided into two categories: on-line and off-line monitoring. By connecting the core of the distribution cable with a coupling capacitor voltage divider or installing a high-frequency current mutual inductance on the shielded grounding wire of the distribution cable Measures such as high frequency curren...
