Abstract

The invention relates to the technical field of power capacitor testing, and discloses a power capacitor test line measurement and control system that comprises the following modules which are connected in sequence: a low-voltage capacitance meter module; a power frequency alternating current voltage withstanding module that is used for carrying out an alternating current voltage withstanding teston the pole-to-shell; a power-frequency direct-current voltage-withstanding module that is used for carrying out an interpolar voltage-withstanding test and a fuse discharge test; a series resonancemodule that is used for carrying out an inter-electrode alternating-current withstand voltage test and carrying out a partial discharge test in a voltage boosting and reducing process; a low-voltagehigh-resistance meter module that is used for measuring discharge resistance; and a data processing subsystem that is used for comparing test data with standard values in a database after the test isfinished to judge whether the test data are qualified or unqualified. The power capacitor is subjected to delivery detection through the low-voltage test before the test, the pole-to-shell power frequency withstand voltage test, the partial discharge test, the inter-pole direct-current fuse discharge test, the inter-pole direct-current fuse discharge test and low-voltage fuse measurement test after the test in sequence, and the system has the advantage that unqualified power capacitors can be accurately detected.

Description

technical field [0001] The invention relates to the technical field of power capacitance testing, more specifically, it relates to a power capacitance test line measurement and control system. Background technique [0002] Power capacitors are capacitors used in power systems and electrical equipment. Any two metal conductors separated by an insulating medium form a capacitor. The size of the capacitance of the capacitor is determined by its geometric size and the characteristics of the insulating medium between the two plates. When the capacitor is used under AC voltage, its reactive power is often used to represent the capacity of the capacitor, and the unit is var or kvar. [0003] As more and more power capacitors are put into operation, damage to power capacitors and explosions often occur. The reasons for the damage are the breakdown of the internal components of the capacitor, damage to the insulation of the capacitor to the shell, and poor sealing and oil leakage. ...
