Abstract

The present invention discloses an electric field sensitive type insulation material static performance test device and system and belongs to the technical field in which electric, electrochemical or magnetic methods are adopted to test and analyze materials. The test system comprises an electric field sensitive type insulation material static performance test device. The test system further comprises a high-voltage direct-current power source, a current limiting resistor, a first pneumatic time delay high-voltage switch K1, a high-voltage non-inductive capacitor, a second pneumatic time delay high-voltage switch K2, a sampling resistor, an oscilloscope, a third pneumatic time delay high-voltage switch K3 and a discharge resistor. According to the test system, capacitor charging and discharging design is utilized, and therefore, damage to a power source caused by the change of the performance of a tested insulation material can be avoided, and the power source can be protected; and the postposition discharging resistor in the test system can fully discharge the residual electric quantity of the capacitor at the end of testing, and the safety of operation can be ensured.

Description

technical field [0001] The invention relates to the technical field of methods for testing or analyzing materials using electrical, electrochemical or magnetic methods, in particular to an electric field sensitive insulating material static performance testing device and system. Background technique [0002] The ideal electric field-sensitive material is an insulating material in the case of low field strength at ordinary times. When the material is excited by an external strong electric field, that is, when the external electric field suddenly increases significantly and exceeds a certain critical field strength, due to the material's unique electrochemical and energy Structural features, able to sense changes in the external electromagnetic environment and quickly adjust its electromagnetic properties, and the insulating / conducting phase transition phenomenon can occur instantly within micro-nanoseconds, and the conductivity can be increased by 10 2 ~10 5 The order of mag...
