Abstract

Disclosed is a current transformer cabinet with a heat dissipation structure. The current transformer cabinet comprises a power cabinet, a function cabinet and a cooling system, wherein the power cabinet and the function cabinet are connected, and the cooling system is installed in the power cabinet. The power cabinet comprises a cabinet body A and a current transformer heating component installed inside the cabinet body A. The function cabinet comprises a cabinet body I, a power distribution component and a grid connection component, wherein the power distribution component and the grid connection component are installed inside the cabinet body I. The cabinet body I is communicated with the lower portion of the side wall of the cabinet body A. The cooling system comprises evaporator fans, a condenser fan, an evaporator, a compressor and a condenser, wherein the evaporator, the compressor and the condenser are sequentially connected to form a closed loop. The closed loop comprises a cooling agent. The evaporator fans comprise the evaporator fan A and the evaporator fan B. The evaporator fan drives airflow internal circulation in the power cabinet. The evaporator fan B is communicated with the ventilation face of the evaporator, and the evaporator fan B and the upper portion of the function cabinet form the airflow internal circulation inside the power cabinet or internal circulation of the function cabinet and the power cabinet. According to the current transformer with the heat dissipation structure, the cooling efficiency of the whole current transformer and the protection level of the whole current transformer are improved, occurrences of condensation of the heat dissipation structure of the current transformer are reduced, the integration of the cooling system and a main machine of the current transformer is achieved, and the structure is compact and reasonable.

Description

technical field [0001] The invention relates to a converter cabinet integrated with a cooling system. Background technique [0002] There are two main cooling methods for existing converter cabinets (including wind power converter cabinets and photovoltaic inverter cabinets). One is that the outside air enters the converter cabinet under the impetus of the fan to form forced convection cooling. It belongs to the open cooling system; the other is that the liquid flows through the radiator under the push of the water pump to form a closed cycle to achieve the purpose of cooling high-power devices, which belongs to the closed cooling system. [0003] like figure 1 As shown, the defect of the open cooling system using air cooling is that some high-power devices (such as frequency converters) are open systems, which must allow material and energy exchange with the outside world, so that dust and sand from the outside are unavoidable. The ground will enter the interior of these ...
