Abstract
An electrified pressure seal clamp for oil charged electrical equipment comprises an upper hoop plate and a lower hoop plate which are mounted correspondingly to form a ring. Wing plates which are arranged at two ends of each of the upper annular hoop plate and the lower annular hoop plate are in mutual correspondence and connected through bolts. The electrified pressure seal clamp is characterized in that the inner surface of the ring formed by the upper and lower hoop plates is provided with an annular groove, and the outer surface of the ring formed by the upper hoop plate and the lower hoop plate is uniformly provided with a plurality of glue filling holes communicated with the annular groove. The electrified pressure seal clamp for oil charged electrical equipment can timely and rapidly handle the defect of leakage and is safe and reliable, degradation, impurity generation and dampening of insulating oil in the oil charged electrical equipment caused by the defect of leakage of the oil charged electrical equipment can be avoided, and accordingly normality in operation of a whole electrical system is guaranteed.
Description
Technical field
The utility model relates to a kind of leakage-baffling device, and particularly oil-filled electrical equipment is with charged pressure sealing anchor clamps.
Background technique
At present, in electric power system, oil-filled electrical equipment occupies quite great proportion, and its stable operation plays crucial effects to whole electric power system.Oil-filled electrical equipment generally uses days longer; Old equipment occupies the majority in the electric substation; The oil-filled electrical equipment of part such as transformer and reactor; Damage, wear out owing to sealing gasket in positions such as its adpting flange, weld seam and valve or the oil circuit weld has reasons such as trachoma, have the seepage oil condition to take place successively.Not only pollute, cause oil level to reduce to device external; More serious is to cause the water content of insulating oil and impurity to increase; Hydrogen content, total hydrocarbon content, air content, breakdown voltage value etc. do not meet the relevant criterion standard in the oil; Influence the equipment state evaluation, equipment safety operation is constituted direct threats.Like untimely leak stopping, device interior possibly break down, and causes taking place protection action, switch trip, causes equipment accident, even might expand as power grid accident, endangers extremely serious.
In a single day oil seepage phenomena appears in oil-filled electrical equipment, needs usually to have a power failure to handle, and needs to change the position that leak source occurs again after the oil extraction, has influenced the normal operation of electric power system greatly, causes heavy losses.In order to address the above problem, at the leak source position leakage-baffling device is set usually, disclose among CN 202118441 U a kind of " Pipe leakage stopper "; It comprises two semi-circle plates, and two arc plate both wings utilize bolt to connect, and arc plate inboard is provided with rubber plate; The corresponding leak source of rubber plate position during leak stopping; Yet rubber plate can not seal the leak source position fully, still can have leak gap, thereby relatively poor to the plugging effect of leak source position.
Summary of the invention
The utility model technical problem to be solved provides a kind of discovery seepage defect in time, handle rapidly, and is safe and reliable, and the good oil-filled electrical equipment of plugging effect is with charged pressure sealing anchor clamps.Avoided causing built-in electrical insulation oil to make moist, produce the generation of situation such as impurity, deterioration, guaranteed that whole electric power system normally moves owing to seepage defect appears in oil-filled electrical equipment.
The technological scheme of the utility model is:
This oil-filled electrical equipment is with charged pressure sealing anchor clamps; Comprise two corresponding upper and lower hoop plates of installing in the form of a ring; Upper and lower hoop plate two ends are respectively equipped with wing plate, and wing plate is corresponding each other and utilize bolt to connect, and its special way is: offer annular groove on the annular inner surface that said upper and lower hoop plate forms; Evenly offer a plurality of hole for injecting glue on the annular outer surface that said upper and lower hoop plate forms, said hole for injecting glue communicates with said annular groove.
Said hole for injecting glue is a tapped hole, to be connected with the firm of injecting glue Tool Room in the assurance injecting glue process.
The beneficial effect of the utility model is:
1, annular groove of offering on the annular inner surface that upper and lower hoop plate forms and leak source and region of interest form chamber; Then this chamber communicates with the hole for injecting glue of hoop plate outer surface; Utilize the high-pressure injection plastic instrument that the leak stopping sealer is injected hole for injecting glue, sealer gets in the chamber and is full of whole cavity space, and the process flowability of sealer and heat cure characteristic make it form closely knit filler; Reach the obstruction leak source, block the purpose that medium leaks; Safe and reliable, plugging effect is good, has avoided causing built-in electrical insulation oil to make moist, produce the generation of situation such as impurity, deterioration owing to seepage defect appears in oil-filled electrical equipment.
2, when seepage defect appears in oil-filled electrical equipment; Can directly utilize these anchor clamps that leak source is carried out rapid shutoff; Most generation leakage defect place is flange, weld seam and valve; If do not have special shape and obstacle, tens minutes to four, five hours just can be leakage cancellation, operating procedure is simple, reliable.
3, owing to do not need to have a power failure, guarantee the requirement of power equipment reliability of operation, and then guaranteed that whole electric power system normally moves, avoided the mistake expenses of surfing in Internet loss that causes because of the elimination defective that has a power failure.
4, owing to do not need oil extraction to handle, greatly reduce maintenance cost.

Fig. 1 is the structural representation (corresponding embodiment 1) of the utility model;
Fig. 2 is along the sectional drawing of A-A among Fig. 1;
Fig. 3 is the structural representation (corresponding embodiment 2) of the utility model.
Among the figure: on bind round plate 1, bind round plate 2, annular groove 3, hole for injecting glue 4, bolt 5, wing plate 6 down.
Embodiment
Embodiment 1
Like Fig. 1, shown in Figure 2; This oil-filled electrical equipment comprises two corresponding installations upward hoop plate 1 in the form of a ring and binds round plate 2 down that upper and lower hoop plate is the semi-circular arc plate with charged pressure sealing anchor clamps; Last hoop plate 1 is respectively equipped with wing plate 6 with the two ends of binding round plate 2 down, and wing plate 6 is corresponding each other and utilize bolt 5 to connect.Offer annular groove 3 on the annular inner surface of last hoop plate 1 and hoop plate 2 formation down; Evenly offer a plurality of hole for injecting glue 4 on the annular outer surface of last hoop plate 1 and hoop plate 2 formation down; Present embodiment is an example with 4; Hole for injecting glue 4 communicates with annular groove 3, and hole for injecting glue is a tapped hole, is used for being connected with the rifle mouth of colloid-injecting gun.
During operation; Hoop plate 1 on these anchor clamps and hoop plate 2 down are sleeved on power equipment leak source place and tight a bolt 5 fixingly, the rifle mouth of colloid-injecting gun is screwed in the hole for injecting glue 4, then high-pressure injection plastic; In the injecting glue process; By the distribution of hole for injecting glue 4 injecting glue successively, the leak stopping sealer is full of in the chamber that annular groove 3 and leak source and region of interest form, form closely knit filling sealer.Because oil-filled electrical equipment working environment of living in is different, in application region not simultaneously, should select suitable leak stopping sealer for use.
As shown in Figure 3, on bind round on plate 1 and hoop plate 2 forms down the annular outer surface and evenly offer 2 hole for injecting glue 4, other are with embodiment 1.
