Description

Technical Field

[0001] The utility model relates to the technical field of insulation protection devices for flexible power transmission and transformation instantaneous power consumption detection, in particular to an insulation protection device for flexible power transmission and transformation instantaneous power consumption detection. Background Art

[0002] Flexible DC power transmission and transformation capacitor is a power electronic capacitor used in flexible DC power transmission (VSC-HVDC) technology. It can provide energy buffering, filtering and voltage stabilization for the DC side of the commutation system. Flexible DC power transmission and transformation capacitors usually use metallized film capacitors because they have the advantages of high voltage and high ripple current resistance, low stray inductance and equivalent series resistance, long life, dry explosion-proof, non-polarity, and good high-frequency performance; the internal series high square resistance film is a new type of metallized safety film, which separates and deposits regular safety film patterns on the insulating material, but the patterns themselves do not cross each other, but are connected to each other through tiny fuses. When the local weakness of the metal film forms a discharge channel, energy quickly rushes in from all directions, and the fuses around the weak small module vaporize and quickly heal themselves without affecting the normal operation of the overall metal film. The internal series high square resistance film can improve the withstand voltage and ripple current capability of the metallized film capacitor, reduce the loss of the fuse part, and work more reliably and safely.

[0003] However, flexible power transmission and transformation generally work in a relatively harsh environment, which may easily cause the flexible power transmission and transformation to malfunction, resulting in reduced reliability of the flexible power transmission and transformation. Therefore, a flexible power transmission and transformation instantaneous power consumption detection fault detection device is needed to detect the flexible power transmission and transformation. The existing flexible power transmission and transformation instantaneous power consumption detection fault detection device has no insulation protection, and the sensor probe is in contact with various sensors for a long time. Long-term use may lead to slow response and other phenomena, and replacement requires replacement of the entire line, which is relatively wasteful. Based on this, an insulation protection device for flexible power transmission and transformation instantaneous power consumption detection is proposed. Utility Model Content
