Abstract

An integrated transformer relates to the technical field of production of outdoor high-voltage permanent-magnet vacuum circuit breakers. A voltage transformer and a current transformer are arranged in an epoxy resin insulating cylinder, and signal outlet terminals of the voltage transformer and the current transformer are arranged at the bottom of the epoxy resin insulating cylinder. Compared with the conventional integrated transformer, the integrated transformer has the advantages that actual current and voltage values on the primary line can be accurately converted into low secondary current and low secondary voltage which cannot interfere with each other to bring convenience to measurement during running due to the fact that the current transformer and the voltage transformer are hermetically cast in a casting body provided with a vacuum arc-extinguishing chamber. Accordingly, error caused by complicated wiring of mounted integrated transformer during mounting on sites can be avoided on the premise of keeping function constant, the mounting process is simplified and the integrated transformer is more attractive in appearance.

Description

technical field [0001] The invention relates to the technical field of outdoor high-voltage permanent magnet vacuum circuit breaker production. Background technique [0002] The current transformers used in medium-voltage vacuum circuit breakers include voltage transformers and current transformers, which are independent of each other. The voltage transformer and current transformer are used in conjunction with the vacuum circuit breaker as an external type, which is large in size, cumbersome in wiring, and consumes installation costs. Contents of the invention [0003] The purpose of the invention is to propose a comprehensive transformer which is convenient to install. [0004] In the present invention, a voltage transformer and a current transformer are arranged in the epoxy resin insulating cylinder, and the signal connection terminals of the voltage transformer and the current transformer are arranged at the lower bottom of the epoxy resin insulating cylinder.
