Abstract

The invention relates to an air-heated internal circulation oven for insulator curing, which comprises a box body. The left and right sides of the box body are provided with a left air duct plate anda right air duct plate which are hollow internally; the left air duct plate and the right air duct plate are internally provided with heating devices and fans; the box body is provided with an air inlet hole corresponding to the fan; the bottom of the box body is provided with a rolling mechanism and a base placed on the rolling mechanism for mounting an insulator mold; and the lower end of the box body is provided with an air outlet communicated with the left air duct plate and the right air duct plate. According to the air-heated internal circulation oven for insulator curing disclosed in the invention, the structure is simple, temperature control in the box body can be realized conveniently, and due to the symmetrical fan design, hot air is blown to the insulator mold at different windspeeds to achieve control on the temperature gradient.

Description

technical field [0001] The invention relates to an oven, in particular to an air-heat internal circulation oven for curing insulators. Background technique [0002] Insulators are the weak link in high-voltage switchgear, especially epoxy cast insulators are widely used in equipment, so its performance will directly affect the operation reliability of switchgear. Experiments have proved that the temperature requirements during the curing and molding process of epoxy resin are relatively strict, which directly affects the curing and molding quality of the insulator. [0003] According to the existing theory and practice, during the curing and molding process of epoxy resin, due to the large volume and mass of UHV insulators, and the entire insulator is in an upright state when curing, the influence of gravity must be considered in actual production . When the insulation is solidified sequentially from bottom to top, the lower insulator solidifies first and shrinks in volume...
