Double-layer ultra-silence power source

Abstract

The invention discloses a double-layer ultra-silence power source. The double-layer ultra-silence power source is structurally characterized in that a diesel engine, an electric generator, an integrated control switch cabinet and an exhaust silencing system are fixed into a power control output layer, the inner wall of the periphery of a double-layer ultra-silence box, a top plate and an air inlet and exhaust partition plate are evenly laid with sound absorption materials, an air inlet and an exhaust opening are formed in the two sides of an air way extension noise reduction layer and are separated through the air inlet and exhaust partition plate, and the air way extension noise reduction layer is divided into an air inlet channel and an exhaust channel; the air inlet channel is communicated with the rear end of the power control output layer, the exhaust channel is communicated with the front end of the power control output layer, and an air inlet and exhaust loop is formed; flow guide plates are arranged on the upper portion and the lower portion of an exhaust cavity; the front portion and the rear portion of each of double sides of the double-layer ultra-silence box are each provided with a climbing ladder stand, the front portion and the rear portion of the top of the box are each provided with a lifting lug and a rope buckle, the two sides of a box body are provided with an overhauling door and an observation door, and an external emergent stop button is arranged at the end; and the power source has the beneficial effects that the double-layer ultra-silence box is adopted, the occupied area is small, mounting is convenient, outdoor use can be directly achieved, a machine room does not need to be constructed, and the use cost is reduced.

Description

technical field [0001] The invention relates to an emergency standby power generation and distribution system, in particular to a double-layer ultra-quiet power supply for providing power to designated equipment after the power system loses the power supply of the power grid outside the plant. Background technique [0002] The double-layer ultra-quiet power supply is mainly used in the emergency backup power system. After the power system loses the power supply of the off-site power grid, it provides power to the designated equipment to ensure its normal operation. However, when ordinary silent diesel generator sets are running, they usually produce relatively loud noises. The current silent power supplies use ordinary silent boxes with only one power control output layer, and the noise leakage from the air intake and exhaust outlets is serious. Contents of the invention [0003] The purpose of the present invention is to make up for the defects of the prior art, and provi...
