Abstract
The utility model provides a front cover assembly of a double PM (Permanent Magnetism) power frequency brushless synchronous generator. The front cover assembly includes a front generator cover, front cover blinds, and a front cover bottom shade. Side air vents are arranged in a left side and a right side of the front generator cover. A bottom air vent is arranged in a lower part of the front generator cover. The front cover blinds are arranged in the side air vents of the front generator cover. The front cover bottom shade is arranged on the bottom air vent of the front generator cover. The side air vents and the bottom side air vent arranged in the front generator cover in the utility model are all used for ventilation. Only when the ventilation is good, the heat dissipation can be good. Thus, the heat dissipation effect of the front cover assembly of the double PM power frequency brushless synchronous generator in the utility model is good, thereby enabling the generator to work normally in a long term. By installing the front cover blinds in the side air vents and installing the front cover bottom shade bottom air vent, foreign matters can be prevented from entering into the generator, thereby accidents of the generator. And fingers or other parts of a human body can be prevented from entering into the generator, thereby avoiding the danger.
Description
Technical field
The utility model relates to the preceding cap assembly of a kind of pair of permanent magnetism power frequency no-brush synchronous generator, belongs to technical field of generators.
Background technology
All seal between the protecgulum of existing generator and bonnet and the shell, cause relying on the fin heat radiation on the shell, radiating effect is relatively poor, makes generator overheating easily, influences the normal use of generator.
Summary of the invention
The purpose of the utility model is in order all to seal between the protecgulum that solves existing generator and bonnet and the shell; Cause to rely on the fin heat radiation on the shell; Radiating effect is relatively poor; Make generator overheating easily, influence the normal problem of using of generator, and then provide a kind of pair of permanent magnetism power frequency no-brush synchronous generator preceding cap assembly.
The purpose of the utility model realizes through following technical scheme:
The utility model comprises: cover at the bottom of preceding cover, protecgulum shutter and the protecgulum; The left and right sides before said on the cover has the avris ventilating opening; The downside of preceding cover has the bottom side ventilating opening; Avris ventilating opening on the preceding cover is provided with the protecgulum shutter, and the bottom side ventilating opening on the preceding cover covers at the bottom of being provided with protecgulum.
Can find out by the above-mentioned technical scheme that provides; Cover is provided with before the utility model avris ventilating opening and bottom side ventilating opening all are used for ventilating; And ventilation effect is good, so the good heat dissipation effect of the utility model, makes generator operate as normal for a long time.Can to prevent that foreign matter from getting into generator inner for cover at the bottom of protecgulum shutter and protecgulum are installed on avris ventilating opening and the bottom side ventilating opening, avoids generator to have an accident, and it is interior and cause danger that finger and other limbs that also can prevent the people get into generator.
