A low-voltage electrical appliance is a component or device that can switch on or off a circuit or non-electrical object manually or automatically according to external signals and requirements to achieve switching, control, protection, detection, conversion, and adjustment of a circuit or non-electrical object. The development of low-voltage electrical appliances depends on the economic development and the needs of the development of modern industrial automation, as well as the research and application of new technologies, new processes and new materials. In terms of worldwide applications, low-voltage electrical appliances are currently developing in the direction of high performance, high reliability, miniaturization, modularization, combination, and generalization of parts.

Communicable

With the development and application of computer networks, low-voltage electrical appliances controlled by computer networks are required to be able to communicate with a central control computer. To this end, various low-voltage electrical appliances have emerged as the times require. Communication low-voltage electrical appliances will become one of the important development directions of low-voltage electrical appliances in the future. In order to achieve the connection between low-voltage electrical components and computer networks, the following three solutions are generally used. One is the development of new interface appliances that connect between the network and traditional low-voltage electrical components. The second is to derive or add computer network networking interface functions to traditional products. The third is the direct development of new appliances with computer interfaces and communication functions.

Intelligent

In order to achieve two-way communication between low-voltage electrical appliances and the central control computer, low-voltage electrical appliances must develop electronically and mechatronics. At the same time, some electrical appliances must have intelligent functions. At present, the development of intelligent electrical appliances is mainly carried out on products such as circuit breakers, molded case circuit breakers, and motor control and protectors. The main feature of the intelligent flower circuit breaker is that it is equipped with an intelligent release. The main feature of the intelligent AC contactor and starter is that it is equipped with an intelligent point system. The control circuit includes a voltage detection circuit, a pull-in signal generation circuit and a hold signal generation circuit. With the development of science and technology, more and more intelligent low-voltage machines have begun to appear in large factories.

High performance, energy saving, miniaturization

除了 In addition to improving the main technical performance of the new low-voltage electrical appliances, it will also focus on pursuing comprehensive technical and economic indicators, such as low-voltage circuit breakers and molded case circuit breakers. In addition to improving short-circuit segmentation capabilities, special attention will be given to reducing the arcing distance. At the same time, its miniaturization is required, which is also very important for the development of a new generation of compact low-voltage complete equipment. For AC contactors, it is no longer a one-sided pursuit of improving the mechanical and electrical life, but the focus of research is on product function combination and derivation, breaking reliability, motion reliability, contact reliability, and energy saving.

Prospect analysis:

In the future, wires and cables and low-voltage electrical appliances will develop together under the impetus of national policies and market conditions.

First, with the continuous and rapid growth of the Chinese economy, it has provided a huge market space for cable products, and the strong temptation of the Chinese market has made the world focus on the Chinese market. In the short decades of reform and opening up, The huge production capacity formed by China's cable manufacturing industry has caught the eye of the world.

Second, in the context of the grand development goals set out in the 12th Five-Year Plan and the sustained macroeconomic growth, investment in fixed assets, industrial production and overall consumption, especially the rapid growth of urban population, will surely drive power generation and electricity Therefore, the future market development space for low-voltage electrical appliances will continue to expand.
