Abstract
The utility model discloses a ring main unit with an internal combustion arc grade lifting reinforcing structure, which comprises a ring main unit body and a cable chamber arranged in the ring main unit body, wherein a cable chamber door of the cable chamber is connected with the side wall of the ring main unit body through a plurality of hooks, and an internal reinforcing door is arranged in the cable chamber door; the looped netowrk cabinet internal side is equipped with epoxy board SMC insulation board with cable chamber door inside, and the cable chamber is equipped with independent pressure release passageway. The utility model provides a current equipment structure unreasonable, the lower not enough defect even of internal combustion arc grade, promote the internal combustion arc grade of looped netowrk cabinet to 20kA 1s, fully improve the protection level to near operation equipment personnel personal safety.
Description
Technical Field
The utility model relates to a power equipment field especially relates to an internal combustion arc grade promotes additional strengthening's looped netowrk cabinet.
Background
The internal combustion arc fault test is a test for protecting personnel in the process of verifying the dangerous electrical effect, and provides a tested protection level for personnel nearby normal operation equipment when the metal closed switch and the control equipment are in normal working positions and an arc fault occurs inside the metal closed switch and the control equipment. Therefore, for the ring main unit, the higher the internal arc grade is, the higher the protection level for personnel near the operation equipment is.
In the prior art, the requirement of the ring main unit internal arc level is not lower than 20kA/0.5s, the ring main units of most manufacturers have unreasonable structures, when the equipment has an internal arc fault, the pressure can not be quickly and effectively relieved, meanwhile, the cable chamber structure of the ring main units can not bear huge heat and pressure generated when the internal arc fault occurs, the cable chamber sheet metal cabinet body is easy to burn through or the cable chamber door plate is washed away, the requirement of the internal arc level can not be met, and the personal safety of personnel near the operating equipment can not be guaranteed. Some manufacturers make certain reinforcing measures on the ring main unit structure, but the internal combustion arc grade can only reach 20kA/0.5s, and although the minimum requirement of the internal combustion arc grade is met, the protection level of the ring main unit structure cannot be further improved, and the protection level of personnel nearby operating equipment cannot be improved.
SUMMERY OF THE UTILITY MODEL
Utility model purpose: the utility model provides a ring main unit of internal combustion arc grade promotion additional strengthening solves the defect that current equipment structure is unreasonable, the internal combustion arc grade is lower not enough even, promotes the internal combustion arc grade of ring main unit to 20kA 1s, fully improves the protection level to near operation equipment personnel personal safety.
The technical scheme is as follows: the utility model discloses a looped netowrk cabinet of inner combustion arc grade promotion additional strengthening, its characterized in that: the cable chamber is internally provided with an inner reinforced door; the looped netowrk cabinet internal side is equipped with epoxy board SMC insulation board with cable chamber door inside, and the cable chamber is equipped with independent pressure release passageway.
Wherein, the looped netowrk cabinet body be the panel beating matter cabinet body.
Wherein, cable chamber door be connected with looped netowrk cabinet body lateral wall through 2 more than couples.
Wherein, cable chamber door all be equipped with a plurality of handle with interior enhancement door.
Wherein, the pressure relief channel is a downward channel with an opening at the bottom.
Has the advantages that: compared with the prior art, the utility model has the following apparent advantage: the utility model discloses a reasonable additional strengthening type, solve the current equipment structure unreasonable, the lower defect not enough even of internal combustion arc grade, promote the internal combustion arc grade of looped netowrk cabinet to 20kA 1s, fully improve the protection level to near operation equipment personnel personal safety.

Detailed Description
The technical solution of the present invention will be further described with reference to the accompanying drawings and the detailed description.
The utility model discloses a looped netowrk cabinet of interior arc grade promotion additional strengthening, including the looped netowrk cabinet body 1 and the looped netowrk cabinet body 1 is equipped with the cable chamber, and cable chamber's cable chamber door 5 is connected with looped netowrk cabinet body 1 lateral wall through a plurality of couple 6, and the cable chamber is equipped with interior enhancement door 4 in cable chamber door 5; the ring main unit 1 is inboard to be equipped with epoxy board SMC insulation board 3 with cable chamber door 5 inside, and the cable chamber is equipped with independent pressure release passageway 2. Wherein, the ring main unit 1 is a metal plate cabinet. Cable chamber door 5 is connected with 1 lateral wall of looped netowrk cabinet body through 2 more than couple 6. Cable chamber door 5 all is equipped with a plurality of handle with interior enhancement door 4. The pressure relief channel 2 is a downward channel with an opening at the bottom.
During the use, the cable chamber inside wall of the looped netowrk cabinet body 1 and the 5 inboard increase installation epoxy board SMC insulation boards 3 of cable chamber door, can effectively reduce the impact of the huge heat that the interior arcing trouble produced to the cable chamber panel beating cabinet body and cable chamber door 5, prevent that the cable chamber panel beating cabinet body and door plant from being burnt through. Adopt the couple mounting means between cable chamber door 5 and the looped netowrk cabinet body 1, the couple firmly fixes on looped netowrk cabinet body 1, can firmly hold cable chamber door 5 when taking place inside arcing trouble, increase simultaneously and install indoor enhancement door 4 of cable, further reduce the huge heat and the direct impact of pressure to cable chamber door 5 that the arcing trouble produced, prevent cable chamber door 5 by burn-through or dash out, further promote the looped netowrk cabinet internal combustion arc grade on the basis of 2 quick pressure releases of pressure release passageway, can effectively promote the looped netowrk cabinet internal combustion arc grade to 20kA 1s, fully improve the protection level to near operation equipment personnel personal safety.
