          2017年5月7日,國家電網公司公示了變電項目2017年夏季變電設備的招標情況。從今年3批招標整體來看,二次設備招標量同比都有明顯增長,一次設備中變壓器、隔離開關和開關柜穩定增長,消弧線圈、直流電源類、避雷器和電容器大幅度增長,組合電器、斷路器、互感器和電抗器小幅度下滑。此次招標66kV及以下電壓等級大部分產品招標量均大規模放大,主要由于國家電網集中招標范圍進一步擴大到中低壓配電設備。

          變壓器:本次變壓器中標總容量合計38591MVA,環比下降-38.49%,同比上升13.20%,2017年3批次招標數量達到去年全年數量的55.73%。由于國家電網擴大招標范圍,66kV及以下招標數量明顯上漲,環比上升105.37%,同比上升106.27%,2017年3批招標達到去年全年數量的94.37%。110kV及以上招標數量環比下滑45.22%,同比上漲14.38%,2017年3批招標達到去年全年數量的54.12%,保持穩定增長。

          開關類產品:總體而言,2017年前3批招標組合電器和斷路器都有明顯的下滑,隔離開關上漲幅度較大。組合電器:本批共招標組合電器1349間隔,環比下降27.43%,同比增長23.65%。隔離開關:本次共招標隔離開關6107組,環比下降3.39%,同比增長91.20%,不過主要是由于66KV及以下招標增長,110KV及以上隔離開關同比招標量增加11.88%。斷路器:本次共招標斷路器1979臺,環比上升5.10%,同比上漲83.58%,但其中110kv及以上同比下降9.61%。開關柜:共招標開關柜10766臺,環比下降6.11%,同比增長39.65%。

          保護類:此次共招標常規站保護設備2394套,環比上升17.81%,同比上升39.35%。其中以線路保護招標最多,共招標1356套。本次共招標智能站保護設備1528套,環比下滑38.98%,同比上漲7.61%。前3批占去年招標總量55.06%。

          變電站監控:此次共中標變電站監控618套,環比上漲7.29%,同比上升42.07%。前3批占去年招標總量79.30%。

          其中,變電站監控系統為448套,相比上一批次有爆發式增長。智能變電站監控系統170套,環比下滑較多。

          互感器:此次共招標6879臺互感器,環比下滑60.10%,同比增長40.02%。消弧線圈:本次國家電網共招標消弧線圈756套,環比下滑13.60%,同比上漲217.65%。避雷器:此次共招標避雷器23496套,環比下滑3.72%,同比上升651.87%。電抗器:電抗器本批招標量與上批相當,為141臺,環比持平,同比下降33.80%。電容器:本次電容器共招標4979套,環比增長9.40%,同比增長492.74%。直流電源類:此次共招標直流電源類設備516套,環比下滑1.90%,同比增長11.45%。 


    On May 7, 2017, the state grid corporation has revealed the bidding for the transformer substation in the summer of 2017. From march tender group as a whole, the secondary equipment tendering has obvious growth, compared to the amount of an equipment transformer, isolating switch, and stable growth of switchgear, arc suppression coil, dc power supply, lightning arrester and capacitor increase by a wide margin, and electric appliances, circuit breaker, transformer and reactor in small increments. Below 66 kv voltage class most of the products in the bidding tender quantity are large amplification, mainly due to the national grid centralized bidding scope to further expand to the low voltage power distribution equipment.

    Combined transformer, this transformer won the bid for the total capacity of 38591 mva, fell to 38.49%, rose 13.20% from a year, in 2017 the number 3 batches tender quantity for all of last year's 55.73%. Due to the national grid for expanding the scope of the tender, tender quantity rise apparently 66 kv and below, rose by 105.37%, rose 106.27% from a year, in 2017, three group of tender quantity for all of last year's 94.37%. The number of bids for 110kV and above was down 45.22 per cent from the previous month, up 14.38 per cent year on year, and the number of tenders in 2017 reached 54.12 per cent for the full year of last year, maintaining steady growth.

    Switching class products: in general, there is a significant decline in the three series of bidding and circuit breakers in 2017, and the isolation switch increases significantly. Combined electrical appliances: the total number of combined bidding and composite appliances was 1349 intervals, down 27.43 percent from the previous month and 23.65 percent year on year. Isolating switch: the tender and isolating switch 6107 group, fell 3.39%, year-on-year growth of 91.20%, but is mainly due to the bidding growth, 66 kv and below 110 kv and above isolating switch bidding quantity increased by 11.88% year-on-year. Circuit breaker: the total bidding breaker in 1979 was up 5.10 percent month-on-month, up 83.58 percent year on year, but 110kv and above were down 9.61 percent year on year. Open ark: total tendering open ark 10766, down 6.11% from month-on-month, up 39.65 percent year on year.

    Protection: the total of 2,394 protective equipment was raised, up 17.81 percent from the previous month, up 39.35 percent year on year. Among them, the bidding for the line protection was the most tendering, with a total of 1,356 tenders. The total number of intelligent stations was 1,528, down 38.98 percent from the previous month, up 7.61 percent year on year. The first three groups accounted for 55.06 per cent of the tender last year.

    Monitoring of substations: the total of 618 units were monitored by the substation, up 7.29% from the previous month, up by 42.07 percent year on year. The first three groups accounted for 79.30% of last year's total.

    Among them, the substation monitoring system was 448 sets, compared with the previous batch of explosive growth. The monitoring system of intelligent transformer substation is 170, which has been down more than the previous month.

    The total of 6,879 transformers, down 60.10% from the previous month, up 40.02% year on year. The arc of the arc: 756 sets of arc of the national power grid, down 13.60 percent from the previous month, up 217.65 percent year on year. Lightning arrester: the total bidding arrester is 23496, down 3.72 percent month-on-month, up 651.87 percent year on year. Electric reactor: the amount of the electric reactor is equal to that of the previous batch, which is 141, which is unchanged from the previous month, and is down 33.80% year on year. Capacitors: the capacitor was tendered for 4,979 units, up 9.40% from the previous month, up 492.74% year on year. Dc power supply: 516 sets of dc power supply, down 1.90% from the previous month, up 11.45% year on year.
