Embodiment
By reference to the accompanying drawings to of the present utility model with thus the structure sentencing the armored withdraw type metal enclosed switch cabinet of device be illustrated.
As shown in Figure 1, 2, of the present utility model with thus the armored withdraw type metal enclosed switch cabinet structure sentencing device be, this switch cubicle include upper static contact 3 thus sentence handcart 5, lower fixed contact 6, second connects copper bar 7, high-tension insulator 8, second main bus bar 9, first main bus bar 15, first connects copper bar 16; Described therefore sentence handcart 5 and be directly connected copper bar 16, second with first by upper static contact 3, lower fixed contact 6 and connect copper bar 7 and connect; Described first connects copper bar 16 is connected with the first main bus bar 15; Described second connects copper bar 7 realizes being electrically connected by the support of high-tension insulator 8 and the second main bus bar 9.
Of the present utility model with thus the armored withdraw type metal enclosed switch cabinet structure function sentencing device be achieved in that
As shown in Figure 1, 2, for KYN-27.5KV with thus sentence the armored withdraw type metal enclosed switch cabinet of device; Fig. 2 is the primary circuit sketch of switch cubicle, shows the major electrical equipment element that cabinet is in-built and copper busbar connected mode.
This switch cubicle include control room 1, handcart room 2, upper static contact 3, cabinet 4 thus sentence handcart 5, lower fixed contact 6, second connect copper bar 7, high-tension insulator 8, second main bus bar 9, wall bushing 10, outlet room, side 11, outlet room, side decompression cover 12, main bus bar room 13, main bus bar room decompression cover 14, first main bus bar 15, first connect copper bar 16, handcart room decompression cover 17; Described control room 1, main bus bar room 13, handcart room 2, outlet room, side decompression cover 12 are interconnected, and are separated by metal foil; Described therefore sentence handcart 5 and be directly connected copper bar 16, second with first by upper static contact 3, lower fixed contact 6 and connect copper bar 7 and connect; Described wall bushing 10 is arranged on the side plate of outlet room 11, side, and the second main bus bar 9 realizes being electrically connected by itself and adjacent cabinet simultaneously.
1, cabinet 4 aluminizing zine plate compacting also assembled formation, cabinet 4 is made up of control room 1, handcart room 2, outlet room, side 11,13 4, main bus bar room compartment.Separate with metallic plate between each room in cabinet 4, spread expansion with Accident prevention.
2, handcart room 2 built with thus sentence handcart 5, wall bushing 10 is equipped with in outlet room, side 11 and wall bushing 10 is equipped with in high-tension insulator 8, main bus bar room 13.Owing to adopting the electric connecting mode of handcart-type, so when there is electric fault, handcart directly can be pulled out cabinet and overhaul again outward, and not affect 27.5KV high-tension circuit normal power supply, namely realize service without power-off.
3 therefore the upper static contact 3 sentencing handcart 5 connects copper bar 16 by first is connected with the first main bus bar 15 of main bus bar room 13; First main bus bar 15 is connected with other cabinet through wall bushing 10; Therefore the lower fixed contact 6 sentencing handcart 5 is connected copper bar 7 with second connects; Second connects copper bar 7 frame on high-tension insulator 8, is connected, realizes electrical connection thus by wall bushing 10 with adjacent cabinet.
4, be arc fault in anti-switch cubicle, handcart room 2, outlet room, side 11, main bus bar room 13, on be respectively equipped with handcart room decompression cover 17, outlet room, side decompression cover 12, main bus bar room decompression cover 14; Handcart room 2, outlet room, side 11, main bus bar room 13 are equipped with arc stream pressure release passage, and passway is located at the top of cabinet 4; Prevent air-flow from being washed open by cabinet front/rear door and injure human body, ensure operator safety.
5, finally do delivery test, can pack after qualified and be transported to in-site installation.
The utility model with thus sentence the armored withdraw type metal enclosed switch cabinet of device, because cabinet adopts aluminizing zine plate, appearance and modeling is more attractive in appearance than welding cabinet, and antiseptic property improves.Owing to realizing closing door operation, after only having high voltage power-off, front/rear door can be opened, and reaches the interlocking functions such as prevention personnel mistakenly entering charged chamber, and security reliability improves.And accurately can judge the character (permanent or transient fault) high-tension line existing fault, expansion accident scope and unnecessary fault is avoided to occur, extension device time between overhauls(TBO) and useful life, effectively can improve the running environment of power supply unit and High-Voltage Electrical Appliances.This will lead a class on electric railway special equipment, and can import substitutes, lay a good foundation for exporting to international market from now on.
According to China's electric railway operation mileage medium-term and long-term plans, about 30,000 kilometers will be increased again to the year two thousand twenty National Electrical mileage of railways.Build a traction substation for approximately every 60 kilometers, each traction substation approximately will install about 30 KYN-27.5kV armored metal enclosed switch equipments.Due to the economy in this product primacy technically and price, determine this product and must produce good market prospects.
