KingSi KSiSA1 Series Electronic Equipment Circuit Breakers Help Made in China 2025 and Industry 4.0

21 Aug,2023


As a crucial component for ensuring the safety of system operation, circuit breakers have been widely used worldwide. As a power system with numerous components, circuit breakers can be used to protect power lines, subsystems, and equipment. When they encounter severe overload or short circuit faults, they can automatically cut off the circuit. Their function is equivalent to the combination of fuse switches and over/under heat relays. Moreover, it is generally not necessary to change the components after breaking the fault current.

With the rapid development of urbanization and industrialization in society, the emergence of intelligent circuit breakers has to some extent alleviated the problem of increasingly precise and integrated equipment and instruments becoming particularly vulnerable to overcurrent and surge. However, complex power systems with multiple components require more reliable load protection. In daily work, our on-site engineers will install various devices in the circuit of the system to protect the load equipment, but the equipment still often encounters some headache equipment failures. These equipment failures may be caused by various factors: increasingly complex circuit systems, aging equipment, humid and polluted environments, mechanical defects that cannot be ignored, insulation failures caused by long-term application of cables, etc. It is not easy for engineers to provide comprehensive protection for the system through traditional methods.

What does intelligent production require?

The demand for high quality and efficiency in intelligent production is constantly increasing, which puts higher demands on the safety and availability of equipment. The downtime of such large-scale systems or the failure of equipment components can cause huge economic losses.

In the control circuit, the switching power supply provides DC voltage for various loads (such as PLC, sensors, actuators, auxiliary relays, solenoid valves, etc.). If the load itself does not have overcurrent protection, corresponding protection needs to be provided. When overload occurs in the circuit, the switching power supply can respond quickly; When a short circuit occurs in the circuit, if the switching power supply cannot provide sufficient short-term overcurrent, common fuses or circuit breakers cannot provide reliable and fast protection for the secondary circuit. Choosing a sufficiently powerful and reliable power supply and suitable protective devices has become an important part of the intelligent production and construction process. The improvement of power selection standards will also add additional costs to enterprises. The traditional circuit breaker or fuse heating protection method cannot adapt to the increasingly intelligent production line requirements due to its inaccurate protection current and breaking time.

Electronic circuit breakers can solve these problems.

When a short circuit or overload occurs in the system, the response speed of downstream protection devices (such as MCBs) is slower than that of switching power supplies, so the faulty circuit cannot achieve selective protection. In this case, it may cause dangerous situations such as voltage drop and even cable fire.

The multi-channel electronic circuit breaker product helps to solve these problems: it can check whether the output current exceeds the rated current, and once such a phenomenon occurs, the semiconductor switch will electronically cut off the output. The tripping time depends on the magnitude of the overcurrent. The measurement of output current, processing and calculation of tripping time, and triggering of semiconductor switches are all achieved through a microprocessor. At the same time, the processor can also monitor one or more output channels, and some models also provide active current limiting function, effectively reducing the power supply pressure of the switching power supply and improving system availability in case of fault.

What is an electronic device circuit breaker?

In industrial control applications, it is usually provided by a DC switching power supply, and electronic equipment circuit breakers are the ideal solution for selective protection of system components in the DC field. It has a selective tripping function, which can provide optimal overload or short circuit protection for various loads, and ensure the normal operation of non fault circuits without being affected, thus ensuring the uninterrupted operation of the production process.

Electronic circuit breakers actually have more flexible and rich tripping curves to match different load characteristics of customers. At the same time, as the optimization of power quality and energy consumption is becoming increasingly important today, low-voltage systems have put forward higher requirements for ordinary circuit breakers. In addition to providing the most basic protection functions, equipment circuit breakers also add a series of convenient functions such as analysis, measurement, and communication. It can be seen that as more intelligent circuit breakers, electronic device circuit breakers can help you optimize and protect your system to a greater extent:

Protect the system from overload and short circuit effects.

Improve electrical energy reliability and optimize circuit allocation

Rich tripping curves, suitable for devices with different sensitivity levels

Accurate tripping without being affected by the length of the front-end line of the load

By using semiconductor power electronic devices to connect and disconnect the power supply circuit, the breaking and closing action time can reach hundreds of us, which can completely solve the arc problem.

The extremely fast fault current cut-off ability can minimize the impact of faults on the power grid while greatly reducing the probability of load damage and improving the safety of the power system.

 

In the new era, electrical products are beginning to emphasize simple installation, exquisite design, and green environmental protection. The multi-channel electronic device circuit breaker has a stable structure, providing reliable protection to you, reducing the frequency of downtime maintenance and equipment replacement caused by load and line conditions, and reducing operation and maintenance costs. At the same time, even with a significant reduction in width and volume, a single channel can still ensure a rated current of 10A. Each channel comes with its own LED light and also has a button function for channel on/off. The independent channel also has measurement and analysis functions, allowing you to comprehensively monitor the current of the entire system and easily achieve the distribution and management of electricity.

Therefore, multi-channel electronic device circuit breakers are no longer traditional circuit breakers in terms of functions, communication, safety monitoring, and system maintenance. They are products that integrate comprehensive energy management and meticulous protection. Jingsi Intelligent continues to be committed to becoming a leader in solid-state circuit breaker products. In the future, we will continue to research and develop key issues, launch more leading and reliable products, contribute to industry development and technological progress, and provide solutions for electrical worry free.
