TH166325A - A circuit breaker that facilitates rapid shifting and arc elongation. - Google Patents

Abstract

The circuit breaker that facilitates rapid movement and arc elongation is composed of a static contact (1), a moving contact (3), and an arc quench (2) contact surface (14) of the contact. Electricity (13) of the static and electrical contact (32) of the moving contact and the lower plane (4) of the acute-angled base placed in the first quadrant. Moving contact parts included With conductive rod (31) and electrical contact The conductive rod has a protrusion (314). The electrical contact is Welded on the distal surface of the protrusion in the direction facing the electrical contact of the static contact, the arc quench is a grid-plate arc quenching hole. The bottom and top of the arc quenching were arranged. There shall be an arc-ignite grid plate (24, 22), respectively, the arc-ignite grid plate on the bottom of the outage box. The arc is more aligned than the electrical contact of the static contact. Plate, grid, grid, ignite the arc on the top. Of the arc quenching cavity is arranged higher than the maximum position of the electrical contact of the moving contact when The moving contact part is opened. The circuit breaker facilitates rapid movement and elongation of the generated arc. Up on the electrical contact of the moving contact and the static contact when the moving contact is opened. With the use of a circuit breaker The arc travel speed and the arc suction length of the circuit breaker can be Are effectively improved without altering the operating mechanism and the housing of the existing circuit breaker Live in the present When a circuit breaker is used in a photovoltaic direct current breaker Working pressure of The circuit breaker can be added. And problems with high volume and high power consumption can be resolved.
