Abstract

The invention discloses an energy saving superposition power distribution cabinet. The power distribution cabinet comprises several sub-power-distribution-cabinet shells which are successively superposed from bottom to top. A lower portion of a left side wall plate of each sub-power-distribution-cabinet shell is provided with an air inlet pipe which is extended to the outside world respectively. An upper portion of a right side wall plate of each sub-power-distribution-cabinet shell is provided with an exhaust pipe which is extended to the outside world respectively. The energy saving superposition power distribution cabinet also comprises a negative pressure fan. An air inlet end of the negative pressure fan is connected to and is provided with one negative pressure wind pipe. Tail ends of the exhaust pipes are connected to the negative pressure wind pipe respectively. The air inlet pipes are provided with regulation valves respectively. Through the above mode, by using the energy saving superposition power distribution cabinet of the invention, one negative pressure fan can be used to simultaneously carry out induced draft and heat dissipation on the several sub-power-distribution-cabinet shells; energy saving performance is good; an air input amount of each sub-power-distribution-cabinet shell is easy to control; adjusting is convenient; a superposition model is realized; the size is small and a suitable scope is wide.
