First Claim
1. An inverter power cabinet, comprising a cabinet body and power devices arranged in the cabinet body, wherein the cabinet body has a low-protection grade installation cavity and a high-protection grade installation cavity, the high-protection grade installation cavity is an airtight cavity;
- the power devices comprise high protection grade power devices arranged in the low-protection grade installation cavity and low-protection grade power devices arranged in the high-protection grade installation cavity, wherein;
the low-protection grade installation cavity has an outer cold air inlet and an inner hot air outlet which are in communication with outside world, and a first fan is further provided in the low-protection grade installation cavity; and
the inverter power cabinet further comprises a heat exchanger configured to dissipate heat of the high-protection grade installation cavity; and
wherein at least one second fan is further arranged in the high-protection grade installation cavity; and
the cabinet body comprises a DC cabinet and an AC cabinet, wherein;
the DC cabinet has the low-protection grade installation cavity and a first high-protection grade installation cavity, and the low-protection grade installation cavity is hermetically separated from the first high-protection grade installation cavity;
the AC cabinet has a second high-protection grade installation cavity; and
the high-protection grade installation cavity comprises the first high-protection grade installation cavity and the second high-protection grade installation cavity.

Abstract
An inverter power cabinet includes a cabinet body and power devices arranged in the cabinet body. The cabinet body includes a low-protection grade installation cavity and an airtight high-protection grade installation cavity hermetically isolated from each other; the power devices include high protection grade power devices arranged in the low-protection grade installation cavity and low-protection grade power devices arranged in the high-protection grade installation cavity; the low-protection grade installation cavity has an outer cold air inlet and an inner hot air outlet in communication with outside world, and a first fan is provided in the low-protection grade installation cavity; and the inverter power cabinet includes a heat exchanger configured to dissipate heat of the high-protection grade installation cavity. The inverter power cabinet can avoid direct contact of the low-protection grade power devices with a harsh environment, thereby preventing the contaminated cold air from damaging the low-protection grade power devices.
