Abstract

The invention relates to a terminal unit, a solid-sealed pole and a circuit breaker using the solid-sealed pole. The terminal unit includes a casting case and terminals arranged in the casting case, and a wireless transmitting module and a sleeve For the power-taking coil on the terminal, a temperature sensor for detecting the temperature of the terminal and electrically connecting with the power-taking coil and the wireless transmitting module is arranged beside the terminal in the pouring shell. The invention solves the problem that in the prior art, because the temperature sensor is arranged outside the pouring shell, it is necessary to install an electrical connector between the temperature sensor and the power-taking coil, the temperature sensor and the wireless transmitting module, resulting in a complex structure of the solid-sealed pole, Technical problem with thick cast shell. The purpose of the present invention is also to provide an embedded pole and a circuit breaker using the embedded pole.

Description

technical field [0001] The invention relates to a terminal unit, a solid-sealed pole and a circuit breaker using the solid-sealed pole, belonging to the technical field of electric equipment. Background technique [0002] The vacuum circuit breaker is an important electrical component in the power system. It plays a role of control and protection in the power system. The solid-sealed pole is an important part of the vacuum circuit breaker. It embeds the vacuum interrupter and the conductive parts related to the circuit breaker into the insulation A pole is formed in the cladding. For example, the Chinese invention patent application with the application number 201210340230.3 discloses a solid-sealed pole, which mainly includes a cast case, an upper terminal, a lower terminal and a vacuum interrupter. The upper terminal and the lower terminal are respectively connected to the vacuum interrupter. At the upper and lower ends, the casting shell is made of epoxy resin material, ...
