Title:
SINGLE-POLE CIRCUIT BREAKER
Document Type and Number:
WIPO Patent Application WO/2022/062214
Kind Code:
A1
Abstract:
A single-pole circuit breaker. The single-pole circuit breaker comprises: a circuit breaker main body (100), which is provided with a main circuit input terminal, a main circuit output terminal (110) and a switch assembly (120), wherein the main circuit input terminal, the switch assembly (120) and the main circuit output terminal (110) are connected to form a main circuit, and a clamping groove (101) for mounting the circuit breaker main body on a guide rail (50) is provided in the bottom of the circuit breaker main body; a circuit control board, which is arranged in the circuit breaker main body (100) and is provided with a first voltage measurement end and a second voltage measurement end, the first voltage measurement end being electrically connected to the main circuit; and a power taking member (200), which is arranged on the circuit breaker main body (100), wherein one end of the power taking member (200) is electrically connected to the second voltage measurement end, the other end of the power taking member (200) is arranged in the clamping groove (101), so as to be electrically connected to the guide rail (50) when the circuit breaker main body (100) is mounted on the guide rail (50), and the guide rail (50) is grounded and connected to the other pole of a power supply, such that a voltage difference between the first voltage measurement end and the second voltage measurement end is formed.
