Description
Technical field
A kind of switchgear is the utility model is related to, is specifically a kind of switchgear inlet-outlet line rain-proof scraping preventing device.
Background technology
When laying the inlet-outlet line cable of high and low voltage switchgear, JP cabinets, outdoor cabinet, cable is easily in the position of wire inlet/outlet hole
Scratch and cause insulating layer damaged；And the leakproofness of wire inlet/outlet hole is poor, there is the defects of roof leaking infiltration, transport for a long time
The security risks such as insulation decline, fever can be produced after row, there is also when serious and burn out even explosion accident.
Utility model content
The purpose of the utility model is to overcome the deficiency in above-mentioned background technology, there is provided a kind of switchgear inlet-outlet line rain-proof is prevented
Device is scraped, which should be able to avoid cable insulation from being damaged when mounted, and have preferable water resistance.
The technical solution of the utility model is：
A kind of switchgear inlet-outlet line rain-proof scraping preventing device, it is characterised in that：The device includes being used to dock switchgear disengaging
The rain cover of string holes and the collar on switchgear wire inlet/outlet hole；The rain cover is curved pipe, one end of curved pipe
Screw hole is equipped with equipped with installing plate and installing plate, the other end of curved pipe sets elastic tape；The internal diameter of the curved pipe with
And the outside diameter of collar and the internal diameter of switchgear wire inlet/outlet hole match；The both ends of the collar have been equipped with the flange of fixation.
The endoporus hole wall of the collar is equipped with some past center position extensions so as to the dust retaining piece for closing endoporus.
The flange includes in-flanges and flanging, and the width of the flanging is more than the width of in-flanges.
The beneficial effects of the utility model are：
The utility model can be occurred by the cooperation of rain cover and collar to avoid during cable laying at wire inlet/outlet hole position
Scratch, extend the service life of cable, be also prevented from rainwater with inside dust access switch cabinet, ensureing the operation peace of equipment
Entirely.
Brief description of the drawings
Fig. 1 is the dimensional structure diagram of the utility model.
Fig. 2 is the main structure diagram of the utility model.
Fig. 3 is the main structure diagram of collar.
Fig. 4 is the dimensional structure diagram of collar.
Embodiment
Below in conjunction with Figure of description, the utility model is described in further detail, but the utility model be not limited to
Lower embodiment.
As shown in Figure 1, a kind of switchgear inlet-outlet line rain-proof scraping preventing device, including rain cover 1 and collar 2.
The rain cover is curved pipe, and the internal diameter of the internal diameter and switchgear wire inlet/outlet hole of curved pipe matches, curved pipe
One end edge is fixed and (is welded and fixed) with installing plate 3 after outwards turning down and is integrated, and installing plate is equipped with some screw holes 31, arc
The pipe other end sets elastic tape 4, and elastic tape wraps the edge of curved pipe.The rain cover is made of stainless steel.
The outside diameter of the collar and the internal diameter of switchgear wire inlet/outlet hole match, shape after the outside fold in both ends edge of collar
Into in-flanges 21 and flanging 22, spacing (i.e. groove 2-1 width) and the cabinet wall thickness of switchgear between flanging and in-flanges
Degree matches, and the width of flanging is more than the width of in-flanges；Therefore after collar is installed on switchgear, groove is with closing cabinet cabinet wall
The edge insertion of the wire inlet/outlet hole of (stainless steel wooden partition) coordinates, and the burr on edge and gap are all blocked covering, avoided
Damage caused by when cable penetrates.The hole wall of collar endoporus is equipped with some dust retaining pieces 23 and (4 gear ashes is shown as in figure at the same time
Piece).The dust retaining piece extends for fan-shaped and toward collar endoporus center position, axis of each dust retaining piece perpendicular to collar endoporus
Line direction, under natural conditions dust retaining piece close the endoporus of collar.The collar is made of rubber.
The installation method of the utility model is as follows：First collar is installed in the wire inlet/outlet hole of switchgear, the both sides of collar
Flange is close to the two sidecar walls (flanging touch the cabinet wall in outside) of outlet hole, then is fixed the installing plate of rain cover with screw
On switchgear, the endoporus of rain cover needs to be directed at the opening down setting of the other end of wire inlet/outlet hole and rain cover.
During non-cabling, dust retaining piece can stop in extraneous dust access switch cabinet.During cabling, cable is filled in
In the opening that rain cover is set downward；As shown in Figure 1, a part for collar protrudes from the inner wall of curved pipe, therefore, collar at this time
It is avoided that the aperture edge of cable and wire inlet/outlet hole scratches, is damaged so as to avoid cable insulation；Meanwhile cable is logical
Dust retaining piece can be pushed when crossing wire inlet/outlet hole open automatically, the collar for wrapping wire inlet/outlet hole is avoided that in exterior dust access switch cabinet,
To keep cleaning in cabinet.
