Document Type and Number:
WIPO Patent Application WO/2020/073847
Kind Code:
A1
Abstract:
A circuit breaker and a double-action transmission device thereof. The double-action transmission device (2) of the circuit breaker comprises a connection rod (21), a connection plate (22), and a connection plate transmission assembly. The connection plate transmission assembly comprises a first connection plate (24) and a second connection plate (25) hinge-connected to the first connection plate (24). An end of the first connection plate (24) away from the second connection plate (25) is hinge-connected to the connection rod (21) by means of a first rotary pin (23). An end of the second connection plate (25) away from the first connection plate (21) is hinge-connected to a driven-side connection member (3) by means of a second rotary pin (26). A first guide hole (221) for the movement of the first rotary pin (23) and a second guide hole (222) for the movement of the second rotary pin (26) are provided on the connection plate (22). In the double-action transmission device, the connection plate transmission assembly comprises the first connection plate (24) and the second connection plate (25), and the length of the first connection plate (24) and the length of the second connection plate (25) are adjusted according to transmission speed requirements, such that the movement speed and the transmission of the connection plate transmission assembly are not affected by the distance between the driven-side connection member (3) and a driving-side connection member (1). Therefore, the invention is applicable to performing breaking at a high voltage level, and the versatility of the double-action transmission device is improved.
