Description
TECHNICAL FIELD
[0001] The application relates to the technical field of power distribution cabinets, and discloses a stacked switch system. BACKGROUND
[0002] In the field of power distribution, an intelligent power distribution cabinet is a key device for distributing, controlling and protecting circuits, and a plurality of circuit breakers and copper bars for connection are usually installed in the cabinet. The circuit breakers include grid-side circuit breakers, bypass-side circuit breakers, diesel generator-side circuit breakers and load-side circuit breakers. In order to save installation space, the circuit breakers are usually arranged in a vertical stacking manner in the cabinet.
[0003] However, due to the heat generated by the circuit breakers and the heat dissipation efficiency in the cabinet, the vertical stacking number of the circuit breakers in the cabinet on the market is limited to three. If the stacking number is forcibly increased, the cabinet will be overheated due to poor heat dissipation, which will seriously affect the reliability and service life of the electrical components. Therefore, in order to achieve necessary heat dissipation, some circuit breakers need to be arranged separately, and the size of the cabinet needs to be increased to increase the heat dissipation space and distance. Based on this setting, the horizontal size of the cabinet is forced to increase, occupying more installation space. In addition, the length of the connecting copper bars between the circuit breakers and between the circuit breakers and the busbars is greatly increased, which not only increases the material cost and the overall weight of the cabinet, but also increases the line impedance and energy consumption. Therefore, improvement is needed. CONTENT OF THE UTILITY MODEL
