Protection device for electrical life test of circuit breaker and operating mode of protection device

Abstract

The invention discloses a protection device for an electrical life test of a circuit breaker and an operating mode of the protection device, and relates to a testing device for a circuit breaker. The device comprises a counter, a start button, a stop button, a timer TI, a timer TII, a timer TI output contact, a timer T II output contact, a timing output contact, a TI buzzer alarm, a TII buzzer alarm, a signal source and a power supply CHI. The operating mode comprises the following steps: executing a function debugging method, to be specific, establishing three corresponding failure models, and establishing corresponding mathematical function models for the three failure models for function debugging; then, starting the electrical life test of the circuit breaker. According to the device and the operating mode, an electrical life test process of the circuit breaker can be targetedly monitored and protected in real time, so that the defects in the prior art that the electrical life test process of the circuit breaker cannot be monitored and protected and no protection measures are provided in case of failures in the test process are overcome.

Description

technical field [0001] The technical solution of the invention relates to a circuit breaker testing device, in particular to a circuit breaker electrical life test protection device and its operating mode. Background technique [0002] Circuit breakers are widely used in industrial and agricultural production. Enterprises are developing and producing new circuit breakers every year, and the products are constantly updated. The electrical life test of circuit breakers is a mandatory type test required by the state, and a large number of circuit breakers need electrical life tests every year. The electrical life test of the circuit breaker needs to be carried out under the rated voltage and rated current provided by the test system, and the test process is a cycle test. According to the national standard, the circuit breaker "closing-opening" is a cycle. Taking the circuit breaker conforming to GB10963.1 as an example, the electrical life test is performed at a rated voltage ...
