Coil-type equipment oil leakage plugging device and method

Abstract

The invention discloses a coil-type equipment oil leakage plugging device and method. The coil-type equipment oil leakage plugging device includes a docking base, the docking base is provided with a through hole and a docking cylinder communicating with the through hole, the docking cylinder and the through hole are coaxial, the docking cylinder is fixed to a docking base through the end, the side, far away from the docking cylinder, of the docking base is used for being attached to the outer wall of a to-be-plugged workpiece, a fastening piece is arranged on the docking cylinder in a matchedmanner, a ring-shaped gasket is arranged between the fastening piece and the outer wall of the to-be-plugged workpiece, the fastening piece cooperates with the docking cylinder to press the gasket tothe periphery of the leakage position, and therefore discharged insulating oil can be drawn out into the fastening piece, the leaked insulating oil is prevented from flowing out from a gap between thedocking base and the outer wall, pollution to a binder applied to the exterior is avoided, the good solidification and sealing performance of the binder is ensured, and the efficiency and the sealingeffect of entire hinge on-line plugging are effectively improved.

Description

technical field [0001] This application relates to the field of electrical maintenance, in particular to a device and method for oil leakage plugging of coil equipment. Background technique [0002] Power grid coil equipment, such as transformers and reactors, often use oil medium to achieve insulation and cooling functions. In actual operation, due to the influence of manufacturing quality, operation and maintenance management, service environment, etc., oil leakage often occurs. Such problems can affect the appearance of the equipment and increase the cost of equipment operation and maintenance. safety; therefore, the treatment of oil leakage from coil equipment has become an important task for the operation and maintenance management of substation equipment; and the conventional treatment method is to pump out the insulating oil and then repair the damaged parts, such as bushings and flanges. After replacement, the insulating oil is purified and then injected into the tr...

Problems solved by technology

In actual operation, due to the influence of manufacturing quality, operation and maintenance management, service environment, etc., oil leakage often occurs. Such problems can affect the appearance of the equipment and increase the cost of equipment operation and maintenance. safety; therefore, the treatment of oil leakage from coil equipment has become an important task for the operation and maintenance management of substation equipment; and the conventional treatment method is to pump out the insulating oil and then repair the damaged parts, such as bushings and flanges. After replacement, the insulating oil is purified and then injected into the transformer. The maintenance process generally takes a long period, and requires high manpower and material costs, which is difficult to meet the current maintenance efficiency requirements; and the glued on-line plugging technology is used , It has obvious advantages to complete the oil leakage plugging of the transformer equipment without power off. This technical method will not affect the normal operation of the equipment. Generally, the local defects of the oil leakage equipment are repaired, so the cost is low. If the material and process are selected reasonably, the equipment after plugging can meet the requirements of long-term service

[0003] The inventor found that although the glued on-line plugging technology can overcome the problems caused by power outage maintenance, it also has inconvenience during the plugging process. , so that the adhesive repair agent will be polluted by the leaked insulating oil, which will lead to a decrease in its sealing ability and reduce the success rate of sealing; at present, some other sealing methods, such as filling the oil leakage gap through plasticine, Apply adhesive repair agent on the outside of the plasticine and the oil leak to isolate the insulating oil to prevent the insulating oil from polluting the adhesive repair agent. However, it is difficult to completely fill the oil leakage gap by the sealing of the plasticine, and it is still unable to achieve a good anti-corrosion effect. Pollution effect; and by sticking the outer wall of the equipment to form an isolation area to accommodate the oil leakage gap and increase the pressure to be equal to the internal pressure of the equipment for sealing, it is necessary to accurately adjust the air pressure to achieve isolation, which is difficult to meet the high efficiency requirements during emergency repairs
