The Circuit breaker

Circuit breaker is to point to to close, bearing and open circuit loop current under the condition of normal and can close, within the prescribed time and open circuit under the condition of abnormal loop current switch devices.Circuit breaker according to its use range was divided into high voltage circuit breaker with low voltage circuit breaker, high and low pressure boundary is fuzzy, divided into general called 3 kv high-voltage electrical appliances.


Circuit breaker can be used to allocate electricity, not frequent start asynchronous motor, the protection of power line and motor, when they happen serious overload or short circuit and under-voltage fault can automatically cut off the circuit, its function is equivalent to fuse switch to owe the combination of thermal relay, etc. And after the breaker fault current generally do not need to change parts. At present, has obtained the widespread application.

The generation of electricity, transportation, use, distribution is a very important link. Distribution systems including transformers, and various high and low voltage electrical equipment, low-voltage circuit breaker is a kind of use bedding face of electrical appliances.

Australian standard circuit breaker development prospects

Although some work has been done in the above aspects for Circuit breaker product reliability research in China, made some progress, but due to the Australian standard residual current circuit breaker reliability research in China started late, many circuit breaker had not carry out the reliability research and the inspection work, at the time of new product development has not yet been reliability design and reliability in manufacturing, especially in our country most enterprise in the industry of circuit breaker do not very attaches great importance to the reliability, reliability work is not serious, the reliability level of circuit breaker products product reliability level is generally lower than developed countries.

In market economy competition, in order to win, win by quality and reliability, will become a consensus. In order to further develop the work of the reliability of the circuit breaker products, in order to improve the reliability level of circuit breaker products in our country, should further do a good job of the following:
(1) As the reliability test device is necessary for reliability verification and test, we should develop all kinds of main circuit breaker products reliability test device.
(2) In addition to the above have made or are making several circuit breaker product reliability test method standard, should be as soon as possible to develop other main circuit breaker products industry standards of reliability test method.
(3) Carry out the circuit breaker product failure analysis work. Failure analysis is to point to analyze the failure products, find out its failure mode and failure mechanism. Find out the problems in the failure analysis, put forward the improvement measures, in order to improve the circuit breaker product reliability.
(4) We should strengthen the popularization of basic knowledge of circuit breaker product reliability work and reliability of talent training, conditional circuit breaker products research institutions and large enterprises can develop some appropriate circuit breaker reliability of master and doctor.
Berise System Integration Co., Ltd.

In order to collect the failure products or the information in the field use, we also need to improve the reliability of the management organization; Failure analysis in order to feedback the information to the department of design department, production department and test, more need to improve the reliability of management organization. Australian standard switch Circuit breaker manufacturing enterprises should strengthen the reliability management. In order to carry out reliability design, reliability test and failure analysis, reliability, production work, must have a sound reliability management organization; therefore, to strengthen the reliability management is very necessary and important.
