Description
Technical Field
The utility model relates to an electric appliance cabinet field especially relates to a automatically controlled cabinet of dust protected crosses line protector.
Background
Electrical cabinets are an important component of power distribution settings. In some occasions, the electric appliance cabinet needs to have higher explosion-proof and dust-proof requirements to prevent external flammable and explosive particles or gas from entering the cabinet body along with air and causing explosion in the cabinet body due to electric sparks; therefore, the requirement on the sealing performance of the electric appliance cabinets is high generally, however, the problem of sealing a bus inlet of an electric control cabinet is still a great technical problem, in the prior art, a wire passing protective sleeve is mostly adopted, the structure is compact and the threading is very difficult for the purpose of sealing effect, and if the number of wires is increased, the trouble is heavy; after threading is completed, the two ends of the rubber sleeve are sleeved, but the operation is complex, the rubber sleeve is easy to age and break in the open air, and the rubber sleeve is very troublesome to replace. Therefore, a dustproof wire passing protection device is needed.
SUMMERY OF THE UTILITY MODEL
The utility model provides a automatically controlled cabinet of dust protected crosses line protector can have fine dustproof effect.
The utility model discloses a realize through following technical scheme:
a dustproof type electric control cabinet wire passing protection device comprises an electric appliance cabinet wall, wherein a through hole is formed in the electric appliance cabinet wall and is provided with an internal thread, a wire passing protection sleeve is screwed in the wire passing hole, and a wire passing hole is formed in the center of the wire passing protection sleeve; the wire passing protective sleeve is of a step-shaped structure, an external thread is arranged at the thinner end of the wire passing protective sleeve to be matched with the via hole, and the thicker end of the wire passing protective sleeve is pressed on the outer wall of the electric appliance cabinet; an annular groove is arranged on the wall of the wire passing hole, and a primary sealing air bag is arranged in the annular groove; an annular groove is arranged on the step surface which is contacted with the outer wall of the electric appliance cabinet, and a secondary sealing air bag is arranged in the annular groove; the first-stage sealing air bag and the second-stage sealing air bag are respectively connected to one side, opposite to the annular groove, of the wire passing protective sleeve and are respectively communicated with the first inflation valve and the second inflation valve.
Preferably, the sharp corners in the annular groove and the annular groove are both in fillet transition.
Preferably, the inflation valve is provided with a plurality of inflation valves.
Preferably, the gap between the air bag and the annular groove is filled with foam material.
The utility model has the advantages that:
1) the built-in air bag is adopted for sealing, the dustproof effect is better than the normal rubber sleeve effect, and the air bag is positioned inside,
the aging is not easy;
2) due to the airtight effect, the structure of the wire passing protective sleeve is not compact, and the wire passing during assembly or the addition of a wire during later maintenance is facilitated.
