Abstract

The invention discloses an epoxy resin pouring tooling for a skeleton coil. The epoxy resin pouring tooling is characterized by comprising a rubber sleeve arranged outside the skeleton wound with thecoil, and a space to be filled with epoxy resin is arranged between the coil and the rubber sleeve. The bottom boss of the rubber sleeve is matched with the inner surface of the skeleton. The two endsof the setting and fixing shell a and the setting and fixing shell b of a setting and fixing device are provided with fixing stops, and the fixing strips of the outer side of the stops are clamped and fixed by dovetail clamps. The pouring process comprises the following steps: preheating and mixing the epoxy resin and the curing agent, vacuum inhaling the epoxy resin and the curing agent with anautomatic potting machine and vacuum defoaming; and pouring is performed from the pouring ports a and b on the skeleton; and placing on a curing platform for curing and demoulding after completion ofpoursing. The advantages are that demoulding saves time and labor, greatly improves demoulding efficiency and effectively avoids mold sticking during demoulding; the tooling can be reused so as to reduce the use cost; and the pouring process is simple, easy to operate, good in pouring effect and high in efficiency.

Description

technical field [0001] The invention relates to the field of epoxy resin pouring, in particular to an epoxy resin pouring tool for a skeleton coil and a pouring process. Background technique [0002] In order to improve the quality and management level of distribution network power supply, promote the construction of smart grid. In recent years, power systems across the country have accelerated the pace of distribution network automation transformation. As an important component, the low-voltage split current transformer is widely used in low-voltage power distribution system automation transformation projects for metering, measurement, comprehensive protection, system monitoring, grounding protection and data analysis. The split-type low-voltage current transformer is easy to install, does not need to be disassembled and installed once, and can be operated live without affecting normal power consumption. It saves time, manpower, and material resources for renovation projec...
