The utility model has the advantages that: the device simple structure of this inlet wire shutoff, convenient to use adopts insulation resin board and the mixed shutoff of fireproofing mud, avoids massive fireproofing mud to drop, absolute can prevent toy access switch cabinet such as mouse inside, avoid high tension switchgear to take place short to ground, switch explosion, threaten equipment, the person is pacified congruent and is endangered.
Description
Technical field
This utility model relates to a kind of power cable field, a kind of device being applicable to the closure of power cable inlet wire.
Background technology
High-tension switch cabinet refers to play break-make for power system generating, transmission of electricity, distribution, electric energy conversion with in consuming, control or the effect such as protection; high-tension switch cabinet is by making the electric pressure electric equipment products at 3.6kV ~ 550kV; high voltage isolator and earthed switch, high voltage load switch, high pressure automatic reclosing and sectionaliser, several big classes such as high-voltage actuating mechanism, high-voltage explosion-proof power distribution equipment and high-tension switch cabinet.Traditional high-voltage switch cabinet wire inlet closure uses fire-proof mud, and (this material is mainly used in electric wire, the holes blocking of cable, to prevent electric wire, cable breaking out of fire from being spread to adjacent room by hole, reduces fire damage.The expansion avoiding accident has resistance cigarette, fire prevention, the function such as dust-proof.Therefore, the electric wire of rectilinear level, the closure of cable penetration hole during DR-A3-JH-1 type fire prevention calking is widely used in the system engineerings such as power plant, industrial and mining establishment, skyscraper, shipbuilding electric power, post and telecommunications, electric substation, metallurgy.), due to the time with expand with heat and contract with cold reason, easily come off, cause inside the toy access switch cabinets such as mouse so that high-tension switch cabinet is short-circuited ground connection, switch blast, jeopardizes equipment, personal safety.
Summary of the invention
The purpose of this utility model is to provide a kind of device being applicable to the closure of power cable inlet wire, the apparatus structure of this inlet wire closure is simple, easy to use, it is prevented from inside the toy access switch cabinets such as mouse, avoid high-tension switch cabinet be short-circuited ground connection, switch blast, jeopardize equipment, personal safety etc. harm.
This utility model adopts the following technical scheme that, a kind of device being applicable to the closure of power cable inlet wire, mainly includes insulating resin plate, fire-proof mud, bracing wire；It is characterized in that: enter cable collar extension position at high-tension switch cabinet and be provided with two pieces of insulating resin plate, enter cable internal orifice position at high-tension switch cabinet and be provided with two pieces of insulating resin plate, arranging fire-proof mud in the middle of collar extension position and internal orifice position, bracing wire is separately positioned in two pieces of insulating resin plate of collar extension position and internal orifice position.
Four pieces of insulating resin plate middle edges of the present utility model dig a little semicircle orifice, and the little semicircle orifice of two pieces of insulating resin plate is combined into a circular hole；This Circularhole diameter size enters cable collar extension openings of sizes according to high-tension switch cabinet and high-tension switch cabinet enters cable internal orifice size and arranges.
Each insulating resin plate of the present utility model is provided with two little projections, is arranged on the insulating resin plate opposite side away from little semicircle orifice, and each bracing wire is separately positioned in two little projections, and the effect of bracing wire is to fix two pieces of insulating resin plate.
This utility model is provided with an insulation sleeve on the cable entering at cable collar extension, and the effect of insulation sleeve is to limit into cable collar extension opening size further so that the toys such as mouse can not be inside access switch cabinet.
The utility model has the advantages that: the apparatus structure of this inlet wire closure is simple, easy to use, use insulating resin plate and fire-proof mud mixing closure, the fire-proof mud avoiding bulk comes off, absolute is prevented from inside the toy access switch cabinets such as mouse, avoid high-tension switch cabinet be short-circuited ground connection, switch blast, jeopardize equipment, personal safety etc. harm.
Accompanying drawing explanation
Fig. 1 is construction profile schematic diagram of the present utility model.
Fig. 2 is the structural representation that two pieces of insulating resin plate of the present utility model combine.
In the drawings, insulating resin plate 1, fire-proof mud 2, bracing wire 3, high-tension switch cabinet 4, enters cable collar extension position 5, enters cable internal orifice position 6, little semicircle orifice 7, little projection 8, insulation sleeve 9, cable 10.
Detailed description of the invention
As shown in Figure 1-2, the utility model is achieved like this, a kind of device being applicable to the closure of power cable inlet wire, mainly include insulating resin plate 1, fire-proof mud 2, bracing wire 3；It is characterized in that: enter cable collar extension position 5 at high-tension switch cabinet 4 and be provided with two pieces of insulating resin plate 1, enter cable internal orifice position 6 at high-tension switch cabinet 4 and be provided with two pieces of insulating resin plate 1, arranging fire-proof mud 2 in the middle of collar extension position and internal orifice position, bracing wire 3 is separately positioned in two pieces of insulating resin plate 1 of collar extension position and internal orifice position；Four pieces of insulating resin plate 1 middle edges dig a little semicircle orifice 7, and the little semicircle orifice 6 of two pieces of insulating resin plate 1 is combined into a circular hole；This Circularhole diameter size enters cable collar extension openings of sizes according to high-tension switch cabinet and high-tension switch cabinet enters cable internal orifice size and arranges；Each insulating resin plate 1 is provided with two little projections 8, is arranged on the insulating resin plate 1 opposite side away from little semicircle orifice 7, and each bracing wire 3 is separately positioned in two little projections 8, and the effect of bracing wire 3 is to fix two pieces of insulating resin plate 1；Being provided with an insulation sleeve 9 at cable collar extension on the cable of 5 entering, the effect of insulation sleeve 9 is to limit into cable collar extension opening size further so that the toys such as mouse can not be inside access switch cabinet.
During use, first according to previous experiences fire-proof mud 2 it is placed in cable collar extension position 5 at high-tension switch cabinet 4 and enters in the passage of cable internal orifice position 6, two pieces of insulating resin plate 1 it is separately positioned on into cable collar extension position 5 and enters cable internal orifice position 6, staff can be according to hole size and the thickness of cable, the on-the-spot size adjusting plugging plate and opening, and material easily obtains, the electric drill of insulating resin plate, common wiring, boring only need to be prepared.
