Abstract
Embodiments of the present specification relate to a circuit breaker control device, a circuit breaker, and a circuit breaker test system, in which: communication is performed with a test device in a data communication manner so as to receive, from the test device, data on information of a test signal for testing a blocking operation of the circuit breaker; a relay element of the test signal is analyzed on the basis of the data; and whether to perform the blocking operation is determined according to an analysis result, and the blocking operation is thus performed according to a determination result.
Claims14
A circuit breaker control device, comprising:
- a communication unit in which communication is performed with an external test device in a data communication manner so as to receive, from the external test device, data on information of a test signal for testing a blocking operation of the circuit breaker;
- and
- a control unit in which a relay element of the test signal is analyzed on the basis of the data, and it is determined whether to perform the blocking operation according to an analysis result, and the blocking operation is thus performed according to a determination result,
- wherein the data is sampling data in which the test signal is sampled at 128 [Bit] by the external testing device.
A circuit breaker which is installed in a switchboard, comprising:
- a blocking operation unit for connecting or disconnecting a circuit between a supply side for supplying electric power and a load side for receiving the electric power;
- a detection unit for detecting at least one of a current and a voltage of the circuit;
- and
- a blocking control unit for determining whether to perform the blocking operation depending on a detection result of the detection unit, or communicating with an external test device in a data communication manner to receive sampling data of a test signal for testing a blocking operation of the circuit breaker from the external test device, and analyzing a relay element of the test signal on the basis of the sampling data to determine whether to perform the blocking
- operation according to an analysis result to control the blocking operation unit according to a determination result, and
- wherein the external test device generates the sampling data by sampling the test signal at 128 [Bit].
A circuit breaker test system, comprising:
- a test device for communicating with a circuit breaker through a wireless data communication manner or a wired data communication manner through a connection of a communication cable to generate sampling data of a test signal for testing a blocking operation of the circuit breaker and transmit the sampling data to the circuit breaker;
- and
- a circuit breaker for receiving the sampling data from the test device, analyzing relay elements of the test signal on the basis of the sampling data, and determining whether to perform the blocking operation according to the analysis result to operate according to a determination result, and
- wherein the test device generates the sampling data by sampling the test signal at 128 [Bit].
