Description
Technical field
The utility model relates to a kind of ventilation filter window, relates in particular to a kind of external maintenance formula ventilation filter window.
Background technology
The cabinet of the equipment such as existing grid-connected current transformer, wind-electricity integration current transformer, power distribution cabinet all needs ventilation and heat, its structure is on cabinet, to be fixedly installed conventional plastics ventilating window, and its maintenance of conventional plastics ventilating window is inconvenient, its material has determined that it there will be aging cracked problem, and plastics ventilating window can make dust enter cabinet, components and parts in attached body are worked the mischief, and plastics ventilating window can't ensure cabinet to carry out effective electromagnetic shielding.
Utility model content
Technical problem to be solved in the utility model is to provide a kind of external maintenance formula ventilation filter window, this ventilation filter window can fast be arranged on cabinet door-plate, this ventilation filter window is easy to maintenance, just can carry out cleaning without opening cabinet, stop plastic ageing embrittlement phenomenon, and ventilation filter window can ensure cabinet to carry out effective electromagnetic shielding, and (first condition code in IP20 refers to prevent dust to make cabinet shell reach the degree of protection of IP20, expression can prevent that diameter is greater than the solid foreign materials that 12mm length is not more than 80mm and enters in shell, can prevent that finger from touching live part or moving component in shell, second condition code refers to waterproof).
For solving the problems of the technologies described above, the utility model adopts following technical proposals: a kind of external maintenance formula ventilation filter window, and it comprises mounting flange, venetian blind type dodge gate, filter web and releasing screw not, described mounting flange is made up of frame and middle part cell structure one, described venetian blind type dodge gate can be fixed on mounting flange in folding, to facilitate in the situation that not opening cabinet, only open dodge gate, just can clear up the mounting flange in dodge gate, this venetian blind type dodge gate size shape is corresponding with cell structure coupling, shutter can avoid liquid splash to enter in cabinet, filter cotton network folder is located between cell structure and venetian blind type dodge gate, make cabinet shell can reach the degree of protection of IP20, between venetian blind type dodge gate and mounting flange, be detachably fixedly connected with by releasing screw not.
Between described venetian blind type dodge gate and mounting flange, for being rotationally connected, be convenient to clear up maintenance.
Between described venetian blind type dodge gate and mounting flange, be rotationally connected by the rotation axis being symmetrical set.
The frame of described mounting flange is provided with link, in order to be fixedly connected with cabinet, the frame coupling of mounting flange is corresponding to the cabinet window of the equipment such as grid-connected current transformer, wind-electricity integration current transformer or power distribution cabinet, realizes being fixedly connected with of mounting flange and cabinet window by the link on mounting flange frame.
Described mounting flange and venetian blind type dodge gate are metal material, to ensure that cabinet is carried out to effective electromagnetic shielding.
The aperture of described filtration web is 30PPI-35PPI (PPI refers to the hole number on per unit inch).The beneficial effects of the utility model are as follows:
The utility model ventilation filter window can fast be arranged on cabinet door-plate, this ventilation filter window is easy to maintenance, just can carry out cleaning without opening cabinet, stop plastic ageing embrittlement phenomenon, and ventilation filter window can ensure cabinet to carry out effective electromagnetic shielding, and make cabinet shell reach the degree of protection of IP20.
