Abstract
The utility model discloses a 12kV switching station structure in a power distribution system. Insulating supports (4) support and fix main busbars (2) on the upper side of a suspended ceiling on the top of a switching station case. The maintenance of the 12kV switching station structure is more convenient, heat-dissipating performance is better, the cost of the case is low, the height of the case is moderate, and the safety is good.
Description
Technical field
The utility model relates to a kind of switchyard in the electrical power distribution system, particularly a kind of 12kV switchyard structure.
Background technology
A kind of switchyard commonly used is equipped with switch cubicle in such switchyard in the electric power power transmission and transformation system of rated voltage 12kV, three-phase alternating current 50Hz.Main bus bar in the switchyard is arranged on the inside of switch cubicle at present, this structure exists many technology and safety problem: 1, when wherein a switch cubicle breaks down, because of switch cubicle also can't be shifted out by the main bus bar string together, very cumbersome to the service work that makes switchyard; 2, the ventilation and heat performance is poor, greatly reduces the current-carrying performance of bus; 3, the height of switch cubicle is higher, and the whole height of switchyard also can't be reduced, and casing furred ceiling volume inside is made casing cost height by idle simultaneously, and brings inconvenience for transportation and installation; 4, main bus bar can not separate fully with switch cubicle, makes the poor safety performance of whole switchyard.
The utility model content
The utility model be at above-mentioned switchyard structure being unfavorable for of existing overhaul, heat dispersion is poor, casing becomes height and drawback such as height superelevation, poor safety performance and design a kind ofly make that the switchyard maintenance is more convenient, heat dispersion is more superior, the casing cost is low and the 12kV switchyard structure highly moderate, that security performance is good.
The technical solution adopted in the utility model is: main bus bar is installed in switchyard furred ceiling top, by the insulation column support fixation.
The 12kV switchyard structure that the utility model provides, because main bus bar is installed in switchyard furred ceiling inside, main bus bar separates fully with switch cubicle, make that switchyard maintenance is more convenient, heat dispersion is more superior, the casing cost is low, make full use of the idle space of switchyard casing furred ceiling inside, reduced the switchyard box height, security performance is good.
Description of drawings
Accompanying drawing 1 is a prior art 12kV switchyard architecture schematic diagram.
Accompanying drawing 2 is the structural representation of an embodiment of the utility model 12kV switchyard structure.
Embodiment
The utility model is described in further detail below in conjunction with accompanying drawing.
In the accompanying drawing: 1, switch cubicle 2, main bus bar 3, casing furred ceiling 4, insulation column
As shown in Figure 2, the main bus bar 2 in the switchyard is installed in furred ceiling 3 tops at switchyard casing top, by insulation column 4 support fixation.
The 12kV switchyard structure that the utility model provides, because main bus bar is installed in switchyard furred ceiling inside, by the insulation column support fixation, main bus bar separates fully with switch cubicle.Do not have main bus bar in the switch cubicle, make each interior switch cubicle of switchyard not by the main bus bar string also not together, it is good conveniently to shift out maintenance and security performance; Because of main bus bar is positioned at casing furred ceiling top, help cross-ventilation, heat dispersion is more superior; Make full use of space in the casing simultaneously, the casing cost is low, and highly moderate.
Claims (1)
1, a kind of 12kV switchyard structure comprises switch cubicle (1), main bus bar (2), casing furred ceiling (3) and insulation column (4), it is characterized in that: main bus bar (2) is supported and fixed on furred ceiling (3) top at switchyard casing top by insulation column (4).
