Abstract

The invention discloses a device for curing memory resin for repairing a circuit breaker. The device is used for solving the problem that no replacement part exists. The device comprises a shell and an electric heating sheet, a water cooling system and a lateral door arranged in the shell, wherein the electric heating sheet is arranged in an upper shell at a joint of a horizontal part and an inclined part; a water cooling pipe in the water cooling system is arranged on the upper side of the electric heating sheet; the water cooling pipe is connected with cold water through a water pump; a first pressing unit and a second pressing unit are mounted in a lower shell; an air blower is fixed in a second cavity; the lateral door can be opened and locked. The resin sheet can be prepared according to the requirements, can be used for replacing a punctured insulating part, and can be on-site manufactured. A special device is adopted for manufacturing, so that the manufacturing standard is increased.

Description

technical field [0001] The invention relates to a spare part for repairing an SF6 circuit breaker and its production equipment, in particular to a raw sheet of special-shaped resin and its curing device. Background technique [0002] The shape memory polymer material is endowed with a certain shape (initial state) under certain conditions. When the external conditions change, it can change the shape accordingly and fix it (such as temperature, electrical stimulation). If the external environment Change again in a specific way and rule, and the shape memory polymer material will reversibly return to the initial state. The whole process completes a cycle: from memory initial state→fixed deformation form→restoring initial state. [0003] For example, the thermotropic type, when the resin is at room temperature, is in a glassy or crystalline state, showing characteristics similar to plastics, and when the temperature rises to a certain stage, such as the soft segment, it shows ...
