Description

Technical Field

[0001] This utility model relates to the field of circuit breaker technology, specifically a multifunctional intelligent frame circuit breaker. Background Technology

[0002] Frame circuit breakers are core devices in power systems, responsible for circuit switching and fault protection, and are widely used in industrial production, building power distribution, and new energy fields. Current traditional products suffer from limitations such as single functionality, limited sensing dimensions, and reliance on manual operation and maintenance. Furthermore, some intelligent products still lack capabilities in multi-parameter collaborative monitoring, remote precise control, and fault prediction. With the advancement of smart grid construction and increasing demands for power reliability, there is an urgent need to develop a multi-functional intelligent frame circuit breaker integrating multiple protection and intelligent management functions.

[0003] Based on the above, the applicant believes the following deficiencies exist:

[0004] The existing temperature monitoring accuracy is insufficient, making it difficult to accurately capture temperature differences at different locations within the enclosure. This can easily lead to missed detections of localized high temperatures, failing to provide comprehensive and accurate temperature data for heat dissipation control. Under prolonged operation or high-temperature environments, the temperature inside the enclosure is prone to exceed the standard, which can cause malfunctions such as failure of electronic components and jamming of mechanical parts in the circuit breaker. This cannot guarantee the continuous and stable operation of the circuit breaker and affects the normal power supply of the power system. Utility Model Content

[0005] The purpose of this invention is to provide a multifunctional intelligent frame circuit breaker to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a multifunctional intelligent frame circuit breaker, comprising a frame circuit breaker, a main control box mounted on the back of the frame circuit breaker, an automatic heat dissipation mechanism provided on the surface of the main control box, and auxiliary protection mechanisms provided on the surfaces of the frame circuit breaker and the main control box.

[0007] The automatic cooling mechanism includes a fan vent located at the top and bottom of the left and right sides of the main control box. Natural air inlets are located at the center of the left and right sides of the main control box. A fixed frame is fixedly connected to the outer ends of the fan vent and the natural air inlets. A dustproof net is installed inside the fixed frame. Temperature sensors are installed at the top and bottom of the left and right sides of the main control box. A cooling fan is installed inside the fan vent. The automatic cooling mechanism includes four sets of temperature sensors, installed at the top and bottom of the left and right sides of the main control box, enabling precise monitoring of the temperature at different locations within the box. The cooling fan is controlled by a temperature sensor and can automatically start and stop according to temperature changes. Together with four sets of fan vents and two sets of natural air inlets, it forms a good air circulation channel to quickly dissipate heat from the main control box, preventing equipment failure due to high temperature and ensuring stable operation of the circuit breaker. At the same time, dustproof nets are installed in the fixed frames at the outer ends of the fan vents and natural air inlets, and the dustproof nets are located outside the cooling fan. This effectively prevents external dust from entering the main control box and prevents dust from adhering to the cooling fan, temperature sensor and other precision components, reducing component wear and the probability of failure, and extending the service life of the entire device.

[0008] Preferably, the dustproof net is installed on the outer end of the cooling fan, the fan cooling vents are provided in four sets, and the natural air inlets are provided in two sets.

[0009] Preferably, four sets of temperature sensors are provided, and the cooling fan is controlled by the temperature sensors.

[0010] Preferably, the auxiliary protection mechanism includes an arc-extinguishing device installed on the top of the main control box. A control gate is located on the front of the arc-extinguishing device, and a top junction box is fixedly connected to the top of the arc-extinguishing device. A terminal block is provided on the surface of the top junction box. A voltage sensor and a current sensor are installed on the top of the front of the frame circuit breaker. These sensors can monitor voltage and current changes in the circuit in real time, promptly detecting abnormal voltage increases or decreases, current overloads, and other abnormal conditions, providing accurate data for subsequent protection actions and facilitating timely detection of potential circuit hazards by personnel. The arc-extinguishing device on the top of the main control box is connected to the control gate. When an arc occurs in the circuit, the arc-extinguishing device can quickly extinguish the arc, preventing fires and other dangers. Simultaneously, the control gate can promptly cut off the circuit to prevent the danger from escalating. Furthermore, the terminal blocks on the surface of the top junction box are equipped with insulating protective sleeves to effectively prevent leakage at the wiring points, reduce the risk of electric shock to operators, and further improve equipment safety.

[0011] Preferably, the output end of the arc extinguishing device is connected to the input end of the control gate, and an insulating protective sleeve is provided on the outside of each terminal block.

[0012] Preferably, the frame circuit breaker is provided with a control panel on the front, and bottom mounting bases are fixedly connected to the bottom of the left and right sides of the main control box, and a back mounting base is fixedly connected to the back of the bottom mounting bases.

[0013] Compared with the prior art, this utility model provides a multifunctional intelligent frame circuit breaker, which has the following beneficial effects:

[0014] 1. This multi-functional intelligent frame circuit breaker is equipped with an automatic heat dissipation mechanism. Four temperature sensors are installed on the top and bottom of the left and right sides of the main control box, accurately monitoring the temperature at different locations within the box. The cooling fans, controlled by the temperature sensors, automatically start and stop according to temperature changes. Combined with the four fan vents and two natural air inlets, this creates a good airflow channel, quickly dissipating heat from the main control box and preventing equipment malfunctions due to high temperatures. This ensures stable operation of the circuit breaker. Furthermore, dust filters are installed inside the fixed frames at the outer ends of the fan vents and natural air inlets, effectively preventing external dust from entering the main control box and adhering to precision components such as the cooling fans and temperature sensors. This reduces wear and tear, lowers the probability of malfunctions, and extends the overall lifespan of the device.

[0015] 2. This multi-functional intelligent frame circuit breaker is equipped with auxiliary protection mechanisms. Voltage and current sensors mounted on the top front of the circuit breaker can monitor voltage and current changes in the circuit in real time, promptly detecting abnormal voltage increases or decreases, current overloads, and other anomalies. This provides accurate data for subsequent protection actions, facilitating timely detection of potential circuit hazards by personnel. The arc-extinguishing device on the top of the main control box is connected to the control switch. When an electric arc occurs in the circuit, the arc-extinguishing device can quickly extinguish the arc, preventing fires and other dangers. Simultaneously, the control switch can promptly cut off the circuit to prevent the danger from escalating. Furthermore, the outer sides of the terminal blocks on the top junction box surface are equipped with insulating protective sleeves, effectively preventing leakage at the wiring points, reducing the risk of electric shock to operators, and further improving equipment safety.
