The invention provides a circuit breaker control device and a circuit breaker, and relates to the technical field of low-voltage electrical switches, and the control device is characterized in that a first terminal is connected with a travel switch, a normally closed contact of the travel switch is connected with a normally closed contact of a first change-over switch, and the first change-over switch and a second change-over switch are respectively connected with an action assembly; a normally closed contact of the second change-over switch is connected with the second terminal; a normally open contact of the travel switch is connected with a normally open contact of the second change-over switch, and a normally open contact of the first change-over switch is connected with the second terminal and used for controlling the action assembly to keep moving in the same direction when the first terminal and the second terminal receive positive and negative electric signals or negative and positive electric signals. A power circuit and a control circuit in an existing circuit breaker are integrated, so that the circuit layout number of the circuit breaker is reduced, the circuit is simplified, and the circuit layout difficulty is reduced.
Description
technical field [0001] The invention relates to the technical field of low-voltage electrical switches, in particular to a circuit breaker control device and a circuit breaker. Background technique [0002] With the rapid development of the economy and the rapid improvement of people's living standards, there is a higher demand for the safety of household electricity. Because of its small size, miniature circuit breakers can be installed in terminal distribution lines. At the same time, it can also connect, carry and break the current under normal or abnormal circuit conditions, forming effective protection for lines and electrical equipment. With the in-depth research on circuit breakers, the technology of remote control circuit breaker opening and closing has gradually matured. [0003] When the existing remote circuit breaker realizes remote action, it needs to connect the power line and the motor to provide power for it. In order to realize remote action, it is also n...
