Energy-saving heat dissipation type photovoltaic combined switch cabinet

Abstract

The invention discloses an energy-saving and heat-dissipating photovoltaic combined switchgear, which includes a cabinet body, the cabinet body is hinged with a cabinet door, and a plurality of grid plates are fixedly connected to the inner cavity of the cabinet body, and the grid plate separates the cabinet body from top to bottom with bus bars Room, switch room and installation room, the top of the busbar room is provided with a cover plate, both sides of the cover plate are provided with exhaust ports, the top of the cover plate is provided with a trumpet-shaped air inlet, the bottom of the air inlet is provided with a water pipe, and the air inlet is close to the end of the cover plate A first ventilation pipe is fixedly connected, and the first ventilation pipe penetrates through the cover plate and the grid plate and enters the bottom of the installation room. Several first air outlets are opened on the outer wall of the first ventilation pipe, and the first ventilation pipe is fixedly connected with a second ventilation pipe. The side of the outer wall of the second ventilation pipe close to the top of the installation room is provided with a number of second air outlets, a water tank is provided at the bottom of the inner cavity of the cabinet, and ammonium nitrate particles are provided above the water tank. The invention has the beneficial effects of reducing power energy consumption and better effectively cooling the cabinet.

Description

technical field [0001] The invention relates to the technical field of electrical equipment, in particular to an energy-saving and heat-dissipating photovoltaic combined switchgear. Background technique [0002] Switchgear is a kind of electrical equipment, its main function is to open and close, control and protect during the process of power generation, transmission, distribution and cable conversion in the power system. Because there are a large number of electrical components in the switchgear, these components generate a lot of heat. At the same time, when the switchgear is installed outdoors, it is also vulnerable to sunlight, and the air circulation is not smooth, which will cause the temperature to rise. If there is no good heat dissipation facility, it is easy to cause Lines and components are damaged, and may burn out and cause a fire in severe cases. Therefore, the heat dissipation measures of the switchgear are very important and necessary. However, the current h...
