Replacement device for sealing ring at oil discharge port of transformer radiator

Abstract

The invention relates to a replacement device for a sealing ring at an oil discharge port of a transformer radiator. The replacement device comprises a fixed element, a support rod and a movable rod,wherein a left clamping block and a right clamping block are arranged above the fixed element; a worm is fixedly arranged below the left clamping block; a fixing screw is arranged at the left side ofthe fixed element; the worm is engaged with a worm gear; the support rod is fixedly arranged below the fixed element; a rotary part is arranged on the lower part of the support rod; a handle is hingedto the rotary part; a rubber ring is arranged on the upper surface of the handle; a location column is arranged at the middle part of the rubber ring; an arc-shaped groove is formed in the lower surface of the handle; the movable rod is arranged at the left side of the support rod; a first adjustment screw rod is arranged on the lower part of the movable rod; a lower clamping shaft is arranged onthe lower part of the first adjustment screw rod; a first adjustment ring is connected to the first adjustment screw rod; a lifting element is connected below the first adjustment ring; and a fixed hook is connected to the lifting element. The replacement device has the advantages of being reasonable in structure, good in blocking effect, and high in replacement efficiency.

Description

technical field [0001] The invention relates to a replacement device for a sealing ring of an oil discharge port, in particular to a replacement device for a sealing ring of an oil discharge port of a transformer radiator. Background technique [0002] The temperature difference between the four seasons where the substation is located is large. The maximum temperature in summer can reach above 40°C, while the temperature in winter can drop below -10°C. Therefore, the expansion and contraction of the metal of the substation is relatively large. Especially in winter, the temperature difference between day and night is extremely high. The temperature is extremely low at night, the elasticity of the sealing rings at the transformer joints is reduced, and the volume shrinks, resulting in oil leakage, and more than 95% of the oil leakage is caused by the sealing rings, so it is necessary to replace the sealing rings in time to prevent oil leakage , but at present, when replacing t...

[0002] The temperature difference between the four seasons where the substation is located is large. The maximum temperature in summer can reach above 40°C, while the temperature in winter can drop below -10°C. Therefore, the expansion and contraction of the metal of the substation is relatively large. Especially in winter, the temperature difference between day and night is extremely high. The temperature is extremely low at night, the elasticity of the sealing rings at the transformer joints is reduced, and the volume shrinks, resulting in oil leakage, and more than 95% of the oil leakage is caused by the sealing rings, so it is necessary to replace the sealing rings in time to prevent oil leakage , but at present, when replacing the sealing ring, since there is no specific replacement device for sealing the oil drain port, it is necessary to temporarily block the oil drain port with rubber sleeves or plugging objects, and then replace the sealing ring manually, but the sealing method is relatively random It may cause oil leakage, and it is time-consuming and laborious to replace; therefore, it is very necessary to provide a transformer radiator oil outlet sealing ring replacement device with reasonable structure, good sealing effect and high replacement efficiency
