浏览次数:14  日期:2017/5/7 2020-05-27

      2017年5月7日,国家电wanggongsi公示了变电项目2017年夏季biandianshe备的招biaoqingkuang。从今年3批招标整体来看,二次设备招标量同比都有明显增长,一次设备中金沙ag,gelikaiguanhekai关柜稳定增长,消弧线圈,直流电源类,避雷器和电容器大幅度增长,zuhedian器,断路器,互感器和电抗器小幅度下滑。此次招标66kV及以下电压等jidabu分产品zhaobiaoliang均大规模放大,主要由于国家电网集中招标范围进一步扩大到中低压配电设备。

      金沙ag:bencijin沙agzhongbiaozong容量合计38591MVA,环比下降-38.49%,同比上升13.20%,2017年3批次招标数量达到去年全年数量的55.73%。由于国家电网扩大招标范围,66kV及以下招标数量明显上涨,环比上升105.37%,同比上升106.27%,2017年3批招标达到去年全年数量的94.37%。110kV及以上招标数量环比下滑45.22%,同比上涨14.38%,2017年3批招标达到去nianquannian数量的54.12%,保持稳定增长。

      开关类产品:总体而言,2017年前3批招标组合电器和断路器都有明显的下滑,隔离开关上涨幅度较大。组合电器:本批共招标组合电器1349间隔,环比下降27.43%,同比增长23.65%。隔离开关:本次共招标隔离开关6107组,环比下降3.39%,同比增长91.20%,不过主要是由于66KV及以下招标增长,110KV及以上隔离开关同比招标量增加11.88%。断路器:本次共招标断路器1979台,环比上升5.10%,同比上涨83.58%,但其中110kv及以上同比下降9.61%。开关柜:共招标开关柜10766台,环比下降6.11%,同比增长39.65%。

      baohulei:此次共招标常规站保hushebei2394套,环比上升17.81%,同比上升39.35%。其中以线路保护招标***多,共招标1356套。本次共招标智能站保护设备1528套,环比下滑38.98%,同比上涨7.61%。前3批占去年招标总量55.06%。

      biandianzhan监控:cicigong中标变电站监控618套,环比上涨7.29%,同比上升42.07%。前3批占去nianzhaobiao总量79.30%。

      其中,变电站监控系统为448套,相比上一批次有爆发shizengchang。智能变电站监控系统170套,环比下滑较多。

      互感器:此次共招标6879台互感器,环比下滑60.10%,同比增长40.02%。消弧线圈:本次国家电网gongzhaobiao消弧线圈756套,环比下滑13.60%,同比上涨217.65%。避雷器:此次共招标避雷器23496套,环比下滑3.72%,同比上升651.87%。电抗器:diankangqi本批招标量与上批相当,为141台,huanbichi平,同比下降33.80%。电容器:本次电容器共招标4979套,环比增长9.40%,同比增长492.74%。直流电源类:此次共招标直流电源类设备516套,环比下滑1.90%,同比增长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.
