Abstract
The utility model discloses a low-noise transformer box which comprises box body. Support cushion feet are arranged at the bottom of the box body. A polyurethane plate is arranged at the bottom of the box body. The support cushion feet are inserted into the polyurethane plate. By utilization of shock absorption character of the polyurethane plate, shock generated when elements work in the transformer box is absorbed so that noise pollution generated by the transformer box can be obviously decreased.
Description
Technical field
The utility model relates to a kind of transformer-cabinet of low noise.
Background technology
In known technical field, transformer tank belongs to a kind of protective device of railway communication signals equipment; the noise that some high-power transformer case produces when work is larger, can produce noise pollution to environment, especially at inhabited environment; in floor, dormitory, affect the comfort of human body.
