[0002] The casting coil mould of a dry-type transformer is a special tool for forming the casting coil of a dry-type transformer. It is usually made of materials with high temperature resistance and good insulation performance to ensure that during the production process of the transformer, the casting coil can be accurately formed according to the design requirements and maintain good insulation performance during operation. The design and manufacture of the casting coil mould require precise engineering calculations and strict process control to meet the electrical performance and mechanical strength requirements of the transformer.
[0003] The casting coil mould of a dry-type transformer is used to ensure that the shape and size of the casting coil meet the design requirements. It helps to maintain the geometric shape of the casting coil, ensure the correct position and tight arrangement of the casting coil inside the transformer, thereby ensuring the performance and reliability of the transformer. The mould can also help improve production efficiency and realize batch production of casting coils. After the casting coil is formed, it needs to be demoulded by a demoulding device. The coil demoulding device demoulds by fixing the casting coil and then using a crane to lift and pull the mould. The problems existing in the above technology are: when encountering products that are difficult to demould, it is easy to cause the crane to be overloaded and damage the products, and sometimes it is impossible to demould. At the same time, it increases personnel operation and there are certain safety hazards, and it will also cause certain damage to the equipment. Summary of the Utility Model
