Abstract

The invention discloses a testing system and method for aging of a three-phase cable. The system comprises a testing operation subsystem, a calculation subsystem and a panel operation subsystem, the testing operation subsystem comprises the three-phase cable, and the three-phase cable is fixed through a cable bayonet; one end of the three-phase cable is fixed to a cable body supporting column, theother end of the three-phase cable is fixed to multiple cable terminal supporting columns, and a grounding line is connected with a negative electrode interface; a shielding ring sleeves the outer side of the three-phase cable and is connected with a grounding electrode interface through conductor connection lines, and a temperature control operation table is connected with a temperature increaseresistor and a temperature sensor separately; the calculation subsystem comprises a controllable frequency-conversion constant-current device, a voltage measurement module and a calculation circuit connected with the voltage measurement module; the panel operation subsystem comprises an image displaying table and a switch position selector, and the calculation circuit is connected with the imagedisplaying table and the switch position selector separately. According to the system, through the three subsystems, the aging process of the three-phase cable can be accurately simulated, the acquired aging result is directly analyzed, and the testing efficiency is improved.

Description

technical field [0001] The present application relates to the technical field of insulation testing of high-voltage equipment, in particular to a three-phase cable aging testing system and method. Background technique [0002] Power cables are used to transmit and distribute electrical energy, and are widely used in power systems due to their advantages of convenient laying, small footprint, and high reliability, and are an extremely important part of the power system. However, in the actual operation process, due to the thermal effect of the current, when the load current passes through the cable, it will inevitably cause the conductor to heat up. At the same time, the skin effect of the charge, the eddy current loss of the steel armor, and the loss of the insulation medium will also generate additional heat. Overload operation will cause the temperature of the cable to rise, which will cause the insulation material of the cable to age, affect the life of the cable, and gre...
