A pull-on circuit breaker for improving safety performance and its realization method

Abstract

The invention provides a switching-off and switching-on breaker for improving safety performance and an implementation method of the switching-off and switching-on breaker. The breaker comprises a contact system, an arc extinction system, an operation mechanism, a tripper and an outer shell, and the switching-off and switching-on breaker comprises a power module 1, a power source module 2, a control module 3, a communication module 4 and a safety module 5. The power source module 2 is respectively connected with the power module 1, the control module 3 and the communication module 4. The control module 3 is respectively connected with the power module 1 and the communication module 4. The safety module 5 is connected with the control module 3. The implementation method comprises the steps that (1), a host sends information to the control module; (2), the control module sends the information to the safety module; (3), the safety module selects a private key, and ciphertext is decrypted and transmitted back to the control module; (4), the control module judges whether cleartext is legal or not; (5), the control module executes corresponding instructions.

Description

technical field [0001] The invention relates to a circuit breaker control device, in particular to a pull-on circuit breaker for improving safety performance and a realization method thereof. Background technique [0002] A circuit breaker is a current switching device that can open and close normal and abnormal circuits, and is a commonly used electrical device in circuits. The traditional circuit breaker has a single function, neither can recognize the complex control commands sent by the host, nor can it feedback the execution results of the commands. Many accidents on the existing circuit breakers are all caused by the failure of the circuit breaker to complete the action after the host computer sends the control command. With the development of science and technology, more complex control requirements are put forward for circuit breakers. [0003] The inventors have done a lot of research and observed that traditional circuit breakers cannot communicate with the host,...

Problems solved by technology

[0003] The inventors have done a lot of research and observed that traditional circuit breakers cannot communicate with the host, and the host cannot obtain the current state of the switch and the execution of control commands, so it is necessary to develop a circuit breaker with an encryption function to realize switch control. Two-way communication between the device and the host, so that on the one hand, the host can understand the current state of the switch more conveniently, and on the other hand, the switch can also timely feedback to the host after executing the command, so as to overcome the traditional circuit breaker that cannot adapt to the development requirements of modern equipment A new type of circuit breaker that can receive control commands sent by the host and can also feedback the execution of the commands in time to achieve two-way interaction with the host
