Problems solved by technology

However, today's casing processing devices and methods adopt complex structures and cumbersome operations, which are not convenient for mass industrial production. Most importantly, the degree of infiltration of fillers such as epoxy resin is low and the distribution is uneven. , the loss of processing medium is relatively large, which makes the pouring and processing effect of dry casing poor, which greatly limits the pass rate and practical application of nonlinear casing production

Abstract

The invention discloses a processing device and method for a dry casing. The device includes a vacuum cavity, a conveying wheel conveying mechanism, a soaking mechanism, a winding mechanism and a curing mechanism; the soaking mechanism and the winding mechanism are both arranged in Inside the vacuum cavity; the vacuum cavity is provided with a feed port and a discharge port; the transfer wheel transport mechanism includes a first transfer wheel, a second transfer wheel and a third transfer wheel located at specific positions; The winding mechanism, which is arranged at the discharge port, is used to wind the soaked crepe paper and aluminum foil, and transport the wound crepe paper and aluminum foil to the curing mechanism . The dry bushing processing device and method provided by the present invention solve the problem of non-uniform distribution of non-linear fillers during the processing of the dry bushing, improve the degree of infiltration, and ensure the relevant electrical performance of the dry bushing. At the same time, the structure topology of the whole set of processing device is clear, and the operation method is simple, which greatly improves the processing efficiency of dry casing.

Description

technical field [0001] The invention relates to the field of manufacturing dry bushings in the electric power industry, in particular to a processing device and method for dry bushings. Background technique [0002] As an important component of power transformers, high-voltage bushings play an important role in transmitting electric energy in high-point fields. They are widely used in power grid systems and other power-related equipment. Their operating conditions directly affect the safe and reliable operation of power systems. In recent years, electrical accidents caused by bushing failures have occurred frequently, and the problem of bushing insulation has gradually attracted the attention of both inside and outside the industry. [0003] The nonlinear bushing can reduce the accumulation of charges inside the bushing, suppress the distortion of the electric field inside the bushing, and reduce the aging and failure probability of the insulation system. Therefore, the insu...
