Problems solved by technology

In addition, the current smart circuit breakers all use external protocol converters for protocol conversion. Good consistency, for example, the performance parameters and settings of smart circuit breakers from different manufacturers are different, and the performance and price of protocol converters from different manufacturers are also quite different, making it difficult for customers to find a circuit breaker that is more suitable for them. And the supporting protocol converter, resulting in the final cost and performance are always unsatisfactory

Abstract

The invention discloses an intelligent molded case circuit breaker which comprises a molded case circuit breaker body. The molded case circuit breaker body comprises a base and an upper cover, wherein the upper cover comprises a panel and a side wall; the panel and the side wall are provided with gaps which are connected, and a first communication interface socket arranged exactly facing to the gap on the side wall is arranged in the upper cover; the intelligent molded case circuit breaker further comprises a communication protocol converter; the inner side end of a communication protocol converter shell body is located in the upper cover, the communication protocol converter shell body is provided with a first communication interface plug matched with the first communication interface socket, and a second communication interface plug matched with a second communication interface socket is arranged at the outer side end of the communication protocol converter shell body; and the communication protocol converter is located in the gap. The communication protocol converter used by the intelligent molded case circuit breaker is convenient to install and use.

Description

technical field [0001] The invention belongs to the technical field of circuit breaker structure design, and in particular relates to an intelligent molded case circuit breaker. Background technique [0002] Compared with most other buses, the Modbus bus itself has many limitations, mainly reflected in low efficiency, poor real-time performance of the system, low communication reliability, high maintenance costs, complex network engineering debugging, unsatisfactory transmission distance, single There are few nodes that can be connected to the bus, and the application is not flexible. However, in the application of industrial field bus, RS485 used by Modbus protocol has a slight advantage in hardware cost and development difficulty, and it is still widely used in China, so it is unrealistic to completely abandon Modbus at this stage, so in practical applications Most of the smart circuit breakers are developed and designed using the Modbus protocol, and then applied to othe...
