In the accompanying drawings: 1, slide block, 2, spring, 3, U-shaped seat, 4, locking iron plate fixing hole, 5, locking iron plate, 6, cover plate, 7, locking iron plate draw-in groove, 8, latch, 9, hook stick.
Embodiment
Below in conjunction with the drawings and specific embodiments, the utility model is described in further detail.
As shown in Figure 1, grounding switch combined floodgate assistor, comprises slide block 1, U-shaped seat 3 and latch 8, and the material of slide block 1, U-shaped seat 3 and latch 8 is iron, and ferrous material low price, should not damage, be easy to cutting processing.Slide block 1 is cuboid, and it has the locking iron plate fixing hole 4 that vertical direction runs through slide block 1, this hole is circular hole, and it is corresponding with locking iron plate 5 that its position is positioned at A face, and its diameter is identical with locking iron plate 5 size, and slide block 1 upper surface is provided with arc groove.A face on slide block 1 has the locking iron plate draw-in groove 7 of horizontal direction, and locking iron plate 5 gos deep into this locking iron plate draw-in groove 7.The inner side of two side arms of U-shaped seat 3 has groove, and two side arm tops are all fixed with cover plate 6 with bolt.Cover plate 6 is cuboid, and its length and width are consistent with the length and width of U-shaped seat 3 two side.The position corresponding with groove of cover plate 6 has hole, is provided with spring stack in groove, spring stack is cylindrical, and on spring stack, cover has extension spring 2, and one end of spring stack is passed the hole of cover plate 6 and is fixed on cover plate 6, and the other end is fixed on the bottom of groove.The both sides of slide block 1 are slidably matched with spring stack by protruding, support below projection with spring 2.Latch 8 is T-shaped, and latch 8 can through the hole on locking iron plate fixing hole 4 and locking iron plate 5.
The locking iron plate 5 of the grounding switch access hole of a certain switch cubicle is between upper and lower two cabinet doors, and upper-lower door spacing is 70mm, and therefore U-shaped seat 3 is of a size of: wide 70mm, high 70mm, thick 30mm.In actual applications, the position of U-shaped seat 3 and size are determined by the actual range between switch cubicle.
Using method of the present utility model is:
The first step, as shown in Figure 2, is positioned over 10kV switch-cabinet grounding knife-switch operating mechanism place by the utility model, locking iron plate 5, facing to switch cubicle, is inserted locking iron plate draw-in groove 7 by A, inserts hole on locking iron plate 5 and locking iron plate fixing hole 4 with latch 8.Because the utility model is ferrous material, badly will causes secondary injury to operating personnel if fixing, lose more than gain, so must by the utility model and locking iron plate 5 fixation.
Second step, presses slide block 1(Vertical dimension in the process of compressing tablet downwards with hook stick 9 and presses down and note not overexerting), until expose grounding switch handle hole.Take advantage of a situation and carry out grounding switch closing operation by hook stick 9 update hole.The utility model takes off by end of operation, carries out the operation of next group switch cubicle.
Use the utility model, operator can complete separately grounding switch closing operation, saves the operating time, improves operating efficiency.
Table 1 and table 2 use Contrast on effect before and after the utility model for certain transformer station 88 10kV dead lines:
Before table 1 uses the utility model, situation is added up
As shown in Table 1,88 10kV line outages in June-2014 years in January, 2014, the conjunction ground cutter used time is longer, and extension device interruption duration, makes operating efficiency reduce.
Table 2 closes ground cutter time and injured number of times statistical form after using the utility model
Can be found out by table 2, average every bar line outage time shortened to 5.3 minutes by 10.7 minutes, and the conjunction grounding switch time shortened to 2 minutes by 5.8 minutes, improve operating efficiency, decrease potential safety hazard, substantially reduce the operating time, thus shorten interruption duration.
