Abstract
The utility model discloses a main bus -bar splint in modified low -voltage distribution cabinet who belongs to low -voltage distribution and energy -saving equipment field. These main bus -bar splint are that mainly female copper bar clamp of arranging is in upper and lower insulating material splint with regarding as among the low pressure alternating current power distribution cabinet, and a metal gusset plate is respectively placed on upper and lower insulating material splint both sides to step up with fixing bolt. The utility model discloses make solid fixed splint metalwork and fixing bolt temperature by dropping to 40~45 DEG C up to 80~95 DEG C, the generating line storehouse does not have the sound, because the temperature reduces, insulation of equipment is ageing slow, and extension equipment life reduces the copper bar and generates heat, increases the copper bar current -carrying capacity, reduces the copper loss.
Description
Technical field
This utility model belongs to low-voltage distribution and energy-saving equipment field, particularly to main bus-bar clamping plate in the low-voltage distribution cabinet of a kind of improvement.
Background technology
Low-voltage distribution cabinet is applicable to exchange 50Hz, rated voltage is for being used as by electricity, feed, mother, illumination, motor and reactive-load compensation in the low-voltage distribution system of 380V, it comprises power center (PC) and motor control center, and is designed to fixing cabinet and drawout cubicle hybrid system to reach different power demands.The middle main bus-bar of traditional low-voltage distribution cabinet is typically arranged on the iron bar support of power distribution cabinet by insulant, when main bus-bar there being electric current pass through, electromagnetic field is produced around main bus-bar, electromagnetic field can produce faradic current on fixing screw and iron bar support, thus cause iron bar backings heated, distribution in-cabinet temperature rises, cabinet drums sound in actual motion, front and back panel vibration cashier's office in a shop, strap metalwork and screw temperature are up to about 80～95 degree on inspection, may result in power distribution cabinet job insecurity and affect working life.
Utility model content
The purpose of this utility model is for producing electromagnetic field around main bus-bar in prior art, electromagnetic field can produce faradic current on fixing screw and iron bar support, thus cause iron bar backings heated, distribution in-cabinet temperature rises, cabinet drums sound in actual motion, front and back panel vibration cashier's office in a shop, may result in power distribution cabinet job insecurity and affects the deficiency of working life, and proposing main bus-bar clamping plate in the low-voltage distribution cabinet of a kind of improvement；It is characterized in that, be clipped in upper and lower insulant clamping plate by copper bar as main busbar in low-voltage alternating-current power distribution cabinet, a nugget genus securing plate is respectively placed on upper and lower insulant clamping plate both sides, and with fixing bolt, nut clamping.
Described metal reinforced plate, fixing bolt, nut are non-magnet material.
Described metal reinforced plate is 304# rustless steel or aluminum alloy plate materials.
Described fixing bolt, nut are rustless steel or copper.
Described insulant is phenolic resin insulant or pottery.
The beneficial effects of the utility model are to make strap metalwork and fixing bolt temperature be dropped to 40～45 DEG C by up to 80～95 DEG C, bus storehouse silent, owing to temperature reduces, apparatus insulated aging slowly, extension device service life, reduce copper bar heating, increase copper bar current-carrying capacity, reduce copper loss.
Accompanying drawing explanation
Fig. 1 is main bus-bar clamp region schematic diagram in low-voltage distribution cabinet.
Detailed description of the invention
The utility model proposes main bus-bar clamping plate in the low-voltage distribution cabinet of a kind of improvement.It is explained below in conjunction with the accompanying drawings.
Fig. 1 show main bus-bar clamp region schematic diagram in low-voltage distribution cabinet.
Copper bar 5 as main busbar in low-voltage alternating-current power distribution cabinet is clipped in the insulant clamping plate 4 being divided into upper and lower two pieces, respectively places a nugget genus securing plate 3 on insulant clamping plate 4 both sides, and clamp with fixing bolt 1, nut 2.The most metal reinforced plate uses the 304# rustless steel of non-magnet material or aluminum alloy plate materials to be processed into.Described fixing bolt, nut all use the rustless steel of non-magnet material or Copper fabrication to make.Make strap metalwork and fixing bolt temperature be dropped to 40～45 DEG C by up to 80～95 DEG C, bus storehouse silent, owing to temperature reduces, apparatus insulated aging slowly, extension device service life, reduce copper bar heating, increase copper bar current-carrying capacity, reduce copper loss.
