Abstract
The utility model discloses a busbar system with air-draft and heat-radiation channels and a corresponding low-voltage switch cabinet. The busbar system is characterized in that the outer wall of an air-draft cylinder structure of the busbar system comprises a busbar-system outer cover (1) and a function-unit-chamber backboard or (laminate board) (8). L-shaped vertical busbars (3) are supportively fixed in the air-draft cylinder through a busbar-clamp base (9), a busbar-clamp cover board (2) and hexagon bolts (5) with insulating sleeves. Structurally formed air-draft and heat-radiation channels (4) (10) are through in a vertical direction. Heat generated during work of the switch cabinet is radiated upwards along the L-shaped vertical busbars (3) through the air-draft and heat-radiation channels. The cylindrical structure makes use of a pressure difference of hot air and cold air in the cylinder and outside the cylinder to speed up upward flow of the hot air in the cylinder and cold air is continuously supplemented at a lower part so that heat radiation of the vertical busbars is speeded up. The busbar system realizes a heat-radiation effect of forced ventilation through a structure of natural air draft so that a temperature rise in an operation of the busbars is reduced. Moreover, installation of a draught fan is not required so that a long-term and reliable operation of the low-voltage switch cabinet is facilitated.
Description
Technical field
The utility model belongs to low-voltage complete switch equipment and control appliance manufacturing technology field, particularly with multifunction board, does the installation of L-type vertical bus, manufacture and the use of insulating and fixing and doing the low pressure drawer-type switch cabinet of a socket use.
Background technology
Along with increasing year by year of power consumption and increasing of power consumption equipment, more and more be used widely as low pressure drawer-type switchgear assembly and the control appliance (low pressure drawer-type switch cabinet) of low-voltage distribution apparatus.
The low pressure drawer-type switch cabinet structure, its drawer unit (functional unit) is all upper and lower vertical pile, several at least, thirties at most.Because the power supply of individual each drawer unit is all taken from the L-type vertical bus, therefore, vertical bus is just carrying whole electric loads of this drawer-type distribution box.In service, the heating at the main circuit plug position plugged with vertical bus and the heating of vertical bus itself have formed the main heating region of low pressure drawer-type switch cabinet.
Position is fixed for vertical bus is carried out, electric insulation, interval isolation and be convenient to each drawer unit main circuit incoming line plug and obtain power supply from vertical bus, people, for MNS type in the past is provided with vertical branch bar system with the most widely used low pressure drawer-type switch cabinet of this class of GCS type, are commonly called as " multifunction board "." multifunction board " is " shell-type " structure, and L shaped vertical bus is enclosed in its airtight housing, only stays minimum jack to insert for the main circuit incoming line plug.Should " multifunction board " be main the composition by outside case, inner " liner plate " two large parts, L shaped vertical bus was embedded in wherein; Be somebody's turn to do the upper and lower port of " multifunction board " also by upper and lower shrouding sealing, around L shaped vertical bus, there is no the space of Air Flow.
Like this, the large factor of radiating requirements two when this class low pressure drawer-type switch cabinet " multifunction board " structure of MNS type in the past and GCS type and operation just is absorbed in the contradiction condition: on the one hand, the vertical bus position has formed the main heating region of low pressure drawer-type switch cabinet, on the other hand, the structure of L shaped vertical bus makes again in its sealing " shell-type " structure that is wrapped in " multifunction board " composition, makes on its plugging position and entire length because the heat that flows through the operating current generation is difficult for distributing.The high temperature that thermal accumlation produces further causes the region of interest ageing of insulation, and the equipment that gently affects is exerted oneself, heavy easily cause the catastrophe failures such as insulation breakdown, electric short circuit.Therefore, how to make the cooling of vertical bus position, be that industry is felt a puzzled difficult problem deeply always.
Summary of the invention
The utility model provides a kind of vertical bus system structure that is easy to dispel the heat, the heat produced while making on L shaped vertical bus plugging position and entire length to flow through operating current very easily distributes, can not produce high temperature rise, thereby guarantee that low pressure drawer-type switch cabinet can move reliably and with long-term.
The utility model is achieved in that at the bus clamping plate of the inner fixed L shape of bus-bar system vertical bus and a plurality of exhausting heat radiation passages is set on every side, this channel vertical direction perforation bus-bar system integral body; On the shrouding up and down of bus-bar system, be provided with the ventilation fence hole.Such bus-bar system structure has formed " suction tube " structure of surrounding L shaped vertical bus.When on L shaped vertical bus plugging position in service and entire length, producing heat, the acceleration that " suction tube " structure that bus-bar system forms utilizes the pressure differential of the outer hot cold air of cylinder inner core to form hot gas in cylinder is upwards flowed, the continuous supplements cold of bottom meeting of " suction tube " structure, thereby accelerated the heat radiation of L shaped vertical bus, reduced temperature rise.The utility model has been realized the radiating effect of forced ventilation by the structure of natural air exhaust, and blower fan need not be installed, and is conducive to low-tension switch cabinet and moves reliably and with long-term.
Second target of the present utility model is the assembling sequence that has changed former multifunction board, L shaped vertical bus, position, functional unit chamber, to facilitate organization of production, reduces manufacturing cost.MNS type and this position assembling sequence of GCS type low pressure drawer-type switch cabinet were in the past: the first step, assembled multifunctional plate case; Second step, assemble L shaped vertical bus; The 3rd step, assembled multifunctional plate liner plate; The 4th step, the assembling function element cell.Use the given structure of the utility model, can first assembling function element cell, then assemble bus-bar system shell and L shaped vertical bus.Its effect is that assembling and replacing parts are easy, facilitate organization of production and on-site maintenance.
The utility model has adopted following technical scheme:
