Abstract

The invention discloses an isolation device for a power electronic device. The isolation device comprises an isolation box body sleeving an isolation object; the isolation box body is internally provided with an insulation fixing device used for fixing the isolation object; the isolation box body is filled with insulating oil; the isolation box body is made of a metal material; the isolation object comprises a power electronic power device and a control driving unit; the isolation box body is provided with an external communication hole which can be insulated and sealed, and an external connecting wire of the isolation object is connected with one or any combination of a power supply, a load and a superior controller through the external communication hole. According to the invention, thepower electronic device can be effectively isolated from an external severe environment under the condition that the temperature of the power electronic device is prevented from being too high due toisolation, therefore the problem that the service life of the power electronic device is shortened due to the fact that the power electronic device breaks down in a severe environment is solved.

Description

technical field [0001] The invention relates to the field of petrochemical equipment, in particular to an isolation device for power electronic devices. Background technique [0002] With the continuous improvement and advancement of various power electronic devices and related technologies, the continuous expansion of their application scenarios has led to more diverse working environments. As a result, some power electronic devices need to work in harsh environments with dust, humidity, low temperature, high temperature or severe air pollution. [0003] The inventor found through research that when some power electronic devices (such as frequency converters, SVG, UPFC, rectifiers, DC power supplies, etc.) Thus affecting the safety and reliability of power electronic devices and their systems. Contents of the invention [0004] Aiming at the deficiencies of the prior art, the present invention provides an isolation device for power electronic devices. The invention can...
