Abstract

The invention discloses a partial discharge detection device, and the device comprises a controller. The controller is connected with an amplification sampling circuit, and the amplification sampling circuit is connected with an A / D conversion circuit. The A / D conversion circuit is connected with a supersonic wave sensor and a pulse generator. The controller and the A / D conversion circuit are connected with a storage unit, and the controller is also connected with a display. The controller is connected with a server through a communication unit. The device can detect the partial discharge of power equipment in real time, and prevents a condition that a fault of the power equipment cannot be known from causing a severer result.

Description

technical field [0001] The invention belongs to the technical field of electric power detection, and in particular relates to a partial discharge detection device. Background technique [0002] The so-called partial discharge refers to the phenomenon that under the action of an electric field, only a part of the electrical equipment insulation system discharges, but does not penetrate between the conductors to which the voltage is applied, that is, no breakdown has yet occurred. The main reason for partial discharge is the inhomogeneity of the dielectric. The electric field intensity of the insulator is not uniform in each area. In some areas, the electric field intensity reaches the breakdown field strength and discharge occurs, while other areas still maintain the characteristics of insulation. In electrical products, the commonly used solid or liquid insulation cannot always be made very pure and dense, and usually contains some dispersed foreign matter to varying degrees...
