[0002] Relay protection is widely used in electric power, transportation, communication and other industries. Before the relay device is officially put into use, the circuit breaker needs to be tested many times. This traditional circuit breaker mainly has the following disadvantages: the circuit breaker is relatively large, and it is difficult to move it. Inconvenient, complicated wiring, time-consuming and labor-intensive; and repeating the whole set of tests, the high-voltage circuit breaker repeatedly trips and closes the test action, shortens the life of the high-voltage circuit breaker, and has an adverse effect on the mechanical structure of the high-voltage circuit breaker

The invention discloses a simulation breaker. The simulation breaker comprises a detection device, a processor, a display and an input button, wherein the processor internally comprises a DC power source circuit, a manual tripping circuit, a manual closing coil circuit and a tripping prevention coil circuit, wherein the detection device is connected with the processor, the processor is connected with the display, and the processor is connected with the input button. The simulation breaker has properties of small volume and convenient use. The simulation breaker module can realize whether external manual closing, external manual tripping, breaker anti-tripping and the tripping loop have maintenance functions and whether the closing loop has the maintenance function. The module is formed by an electronic circuit, can completely simulate motion logic of a breaker mechanism, can specifically detect whether the maintenance loop in a microcomputer device is normal, greatly reduces the volume of matching test equipment, greatly improves production and detection efficiency and greatly reduces cost of the matching test equipment.
Description
technical field [0001] The invention relates to a circuit breaker, in particular to a simulated circuit breaker and a testing method thereof. Background technique [0002] Relay protection is widely used in electric power, transportation, communication and other industries. Before the relay device is officially put into use, the circuit breaker needs to be tested many times. This traditional circuit breaker mainly has the following disadvantages: the circuit breaker is relatively large, and it is difficult to move it. Inconvenient, complicated wiring, time-consuming and laborious; and repeating the whole set of tests, the high-voltage circuit breaker repeatedly trips and closes the test action, shortens the life of the high-voltage circuit breaker, and has an adverse effect on the mechanical structure of the high-voltage circuit breaker. [0003] Therefore, there is a need for an analog circuit breaker that can replace the circuit breaker. Contents of the invention [000...
