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

Example Embodiment

[0034] Example 1

[0035] In a typical implementation of the present application, such as figure 1 As shown, a device and method for oil leakage plugging of coil type equipment applied to the outer wall of a planar workpiece are proposed.

[0036]The blocking device mainly includes three parts, a docking base, a gasket and a fastener. In this embodiment, the docking base is a bonding base 3 provided with a through hole and a docking cylinder communicating with the through hole. The bonding base is a planar plate, which is used to fit the planar outer wall of the workpiece to be blocked. The butt joint is arranged coaxially with the through hole and fixed on the joint base through the end. The joint joint and the fastener To cooperate, an annular gasket is provided between the fastener and the outer wall of the workpiece to be blocked. In this embodiment, the fastener is selected from a cylindrical fastening bolt cap 1 with one end closed, which has a A cavity, after cooperat...

Example Embodiment

[0047] Example 2

[0048] In a typical implementation of the present application, such as figure 2 As shown, a device and method for oil leakage plugging of coil type equipment applied to the outer wall of arc-shaped workpieces is proposed.

[0049] The difference from Embodiment 1 is that in this embodiment, the bonding base 4 is an arc-shaped plate, and while the sealing ring 5 is arranged between the fastening bolt cap 7 and the outer wall of the workpiece, a sleeve 6 is also added as a The middle fastener, the fastening bolt cap is a cylindrical structure with one end blocked, and a sleeve is fitted inside, one end of the sleeve contacts the fastening bolt cap, and the other end fits the sealing ring, and the fastening bolt cap Press the sealing ring through the sleeve to make the sealing ring close to the outer wall of the workpiece;

[0050] Further, one end of the sleeve fitting the gasket is an arc-shaped structure matching the outer wall of the workpiece to be seal...

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...
