Single pole assembly tool for immobilized and encapsulated post terminal and casting method for immobilized and encapsulated post terminal

Abstract

The invention relates to a single pole assembly tool for an immobilized and encapsulated post terminal and a casting method for the immobilized and encapsulated post terminal. The single pole assembly tool for the immobilized and encapsulated post terminal comprises a wire outgoing base support frame. the wire outgoing base support frame is provided with an upper wire outgoing base positioning structure and a lower wire outgoing base positioning structure, wherein the upper wire outgoing base positioning structure and the lower wire outgoing base positioning structure are used for enabling an upper wire outgoing base and a lower wire outgoing base for the single pole assembly of the immobilized and encapsulated post terminal to meet a preset positional relationship. The single pole assembly tool further comprises a wire outgoing base connecting piece. The wire outgoing base connecting piece is provided with a fixation part fixedly connected with one of the upper wire outgoing base and the lower wire outgoing base, and a positioning part in axial and circumferential location fit with the other one of the upper wire outgoing base and the lower wire outgoing base. By using the above tool, the single-pole assembly of the above immobilized and encapsulated post terminal is prevented from relatively rotating or axially moving to cause the relative position change during the transferring and preheating process. Therefore, the assembling efficiency and the die-filling efficiency of the single-pole assembly of the immobilized and encapsulated post terminal are ensured. Meanwhile, the yield and the production efficiency of the immobilized and encapsulated post terminal are ensured. The cost is lowered.

Description

Technical field [0001] The invention relates to a solid-sealed pole unipolar assembly tooling and a solid-sealed pole pouring method. Background technique [0002] The solid-sealed pole is the core component of the vacuum circuit breaker. It is used to replace the previous unipolar structure of the insulating cylinder and is installed on the solid-sealed indoor high-voltage vacuum circuit breaker. The APG epoxy resin casting process is used in the production of the solid-sealed pole. The unipolar assembly needs to be assembled before pouring, that is, the vacuum interrupter and the upper and lower outlet sockets are assembled into an assembly with a certain positional relationship, and then the unipolar assembly Install into the mold for pouring. [0003] For solid-sealed poles with a rated voltage of 12kV and a rated current of more than 2000A, for example, the solid-sealed pole disclosed in the Chinese patent with application number 201510814167.6, application publication number...
