Problems solved by technology

[0002] At present, high-voltage vacuum circuit breakers are widely used in complete sets of switchgear for power transmission and distribution. The vacuum interrupter generally adopts the sleeve assembly form, which is easily restricted by pollution, moisture, wind and sand, etc., which reduces the electrical performance of the product and has a short service life.

Embodiment Construction

[0009] Such as figure 1 As shown, the present invention is a novel solid-sealed pole vacuum circuit breaker, which includes a vacuum interrupter 1, an upper contact arm 2 and a lower contact arm 3, and the vacuum interrupter 1 is connected to the upper contact arm 2 and the lower contact arm respectively. The arms 3 are solid-sealed together, and the solid-seal is specifically made of epoxy resin material and poured through automatic pressure gelling process (APG).

[0010] In the present invention, the vacuum interrupter 1, the upper contact arm 2 and the lower contact arm 3 are sealed together by epoxy resin, which not only reduces the oxidation of the conductive parts of the circuit breaker, reduces the circuit resistance, but also improves the connection of the main circuit. Reliability, and at the same time, the vacuum interrupter 1 is provided with more sufficient mechanical protection after adopting solid seal casting.

Abstract

The invention relates to a novel vacuum circuit breaker with a fixedly encapsulated pole. The vacuum circuit breaker comprises a vacuum arc-extinguishing chamber (1), an upper contact arm (2) and a lower contact arm (3) and is characterized in that the vacuum arc-extinguishing chamber and the upper contact arm (2) are fixedly encapsulated. The novel vacuum circuit breaker with the fixedly encapsulated pole adopts a high performance epoxy resin material, utilizes the automatic pressure gel (APG) process to fixedly encapsulate the vacuum arc-extinguishment chamber, the upper contact arm and the lower contact arm, is suitable for working environment with large sand, dryness, plateau highness and coldness, moisture, foul, underground and power stations, simultaneously reduces oxidation of conductive parts of the circuit breaker, reduces circuit resistance and improves main circuit connection reliability. Experiments prove that mechanical service life can reach 30000 times.

Description

technical field [0001] The invention relates to a novel solid-sealed pole vacuum circuit breaker. Background technique [0002] At present, high-voltage vacuum circuit breakers are widely used in complete sets of switchgear for power transmission and distribution. The vacuum interrupter generally adopts the sleeve assembly form, which is easily restricted by pollution, moisture, wind and sand, etc., which reduces the electrical performance of the product and has a short service life. . Contents of the invention [0003] The purpose of the present invention is to provide a novel solid-sealed pole vacuum circuit breaker, which can be used in harsh working environments and improves the reliability of the main circuit connection. [0004] A novel solid-sealed pole vacuum circuit breaker includes a vacuum interrupter, an upper contact arm and a lower contact arm, and its special feature is that the vacuum interrupter and the upper contact arm are sealed together.
