Description
Technical Field
The utility model relates to a cubical switchboard cabinet body and cubical switchboard.
Background
Along with the popularization of the intelligent power grid, relevant intelligent equipment is urgently needed in the market, and the intelligent transformation of the traditional transformer substation and the intelligent application of a newly designed transformer substation are imperative. The switch cabinet is one of the most common devices in the power field, and the reliability, the controllability and the safety of the switch cabinet directly influence the safe operation and the fault prevention of a power system. KYN28A-12 cubical switchboard is often used in power system electricity generation, distribution and electric energy conversion, plays the effect such as break-make, control or protection. The KYN28A-12 switch cabinet is an electric appliance product with the voltage grade of 10KV, and mainly comprises a high-voltage circuit breaker, a grounding switch, a mutual inductor and the like.
The cabinet top of cubical switchboard need set up be used for with the cubical switchboard that sets up side by side is connected female arranging, female arranging for three and be a row and open, like the utility model patent of the grant bulletin number CN205231606U discloses a cubical switchboard. As certain air insulation distance (the minimum value of 10kV is 125 mm) is required between the busbars on the top of the switch cabinet. At present, due to the limitation of the width of a busbar, the loaded rated current of a domestic KYN28A-12 switch cabinet with the cabinet width of 800mm cannot exceed 1250A (at the moment, the width of the busbar is about 80 mm). When the loaded rated current of the KYN28A-12 switch cabinet exceeds 1250A, if the rated current is 4000A (at the moment, the specification of the busbar is 125mm x 10 mm), in order to meet the requirement of the air insulation distance between the three-phase busbars on the top of the switch cabinet, the cabinet width of the KYN28A-12 switch cabinet needs to be 1000 mm. However, some substations are limited by installation space and arrangement sequence of cabinets, the cabinet width of a KYN28A-12 switch cabinet which requires loading rated current to exceed 1250A is 800mm, but the existing switch cabinet cannot meet the requirement of the insulation distance of busbar air.
