Description

Technical Field

[0001] This utility model relates to the field of circuit breaker equipment, and in particular to a novel circuit breaker equipment with metering function. Background Technology

[0002] Circuit breakers are important protective devices in power distribution systems. They can quickly disconnect the circuit when faults such as overload and short circuit occur, ensuring electrical safety. They are switching devices that can close, carry, and interrupt current under normal circuit conditions, and can carry and interrupt current under abnormal circuit conditions within a specified time.

[0003] Chinese Patent Publication No. CN206619555U discloses an automatic reclosing circuit breaker with metering function, including a circuit breaker housing and a reclosing housing connected together. The circuit breaker housing has an inlet terminal and an outlet terminal at both ends. A metering device for measuring electricity consumption is electrically connected to the inlet terminal. However, existing devices have some shortcomings. Existing circuit breakers generally adopt an integrated structure design, integrating the metering device, display device, and circuit breaker into one unit. However, during use, circuit breakers are prone to damage due to poor line contact, overload, short circuit, improper arc handling, installation problems, etc., which requires replacement. However, replacing the entire circuit breaker results in high operating costs. Therefore, we propose a new type of circuit breaker device with metering function to solve the above problems.

[0011] In a further embodiment, the mounting assembly includes a mounting plate located on the back of the protective housing, and the outer surface of the mounting plate has a plurality of mounting holes.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] This utility model discloses a novel circuit breaker device with metering function. By adopting a split design, the circuit breaker body is separated from the display component and protective shell. When the circuit breaker body is damaged due to a fault, only the circuit breaker body needs to be replaced, without replacing the entire device, which greatly reduces the cost of use. At the same time, the connecting component enables quick circuit connection, and the bolt fixing structure of the fixing component makes the installation and replacement of the circuit breaker body without the need for professional tools, making the operation convenient.

Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] Please see Figure 1-4 In this utility model, a novel circuit breaker device with metering function includes a protective shell 1, which serves as the main frame of the device. The front of the protective shell 1 integrates display and circuit breaker installation functions, while the back is provided with a structure for overall fixation. The front of the protective shell 1 is respectively equipped with a display component 3 and a device component 4. The front of the device component 4 is equipped with a fixing component 5 for stably fixing the circuit breaker body 8 inside the device component 4. The back of the device component 4 is equipped with a connecting component 6 for quickly connecting the circuit breaker body 8 to an external circuit. The back of the protective shell 1 is equipped with an installation component 2. The display component 3 is used to display electricity metering data and device status in real time, and the device component 4 is used to install the circuit breaker body 8. The installation component 2 is used to fix the entire device to a wall or mounting bracket.

[0023] The display component 3 includes a display screen 11 and a warning light 12. Both the display screen 11 and the warning light 12 are located on the front of the protective housing 1. The display screen 11 can display metering data such as current, voltage, and power consumption in real time. The warning light 12 includes three status indicator lights: normal operation, overload, and short circuit, which are indicated by different colors. When an abnormality occurs in the circuit, the warning light 12 of the corresponding color will light up, making it easy to quickly identify the type of fault.

[0024] The equipment component 4 includes a mounting slot 9, which is located on the front of the protective housing 1. The circuit breaker body 8 is installed inside the mounting slot 9. The size of the mounting slot 9 matches that of the circuit breaker body 8, and an insulating pad is provided inside the slot to avoid the risk of leakage caused by direct contact between the circuit breaker body 8 and the protective housing 1. The circuit breaker body 8 adopts a modular design and integrates short-circuit protection, overload protection and metering sampling functions. Its metering data can be transmitted to the display component 3 through the internal circuit.

[0025] The fixing assembly 5 includes a fixing plate 15 and two fixing holes 18. The fixing plate 15 is located on the outer surface of the circuit breaker body 8. Two connecting holes 16 are opened on the outer surface of the fixing plate 15. Fixing bolts 17 are placed inside the two connecting holes 16. The two fixing holes 18 are located on the front side of the mounting groove 9. The two fixing bolts 17 are threaded to the two fixing holes 18 respectively. The fixing plate 15 is integrally formed with the circuit breaker body 8. The two connecting holes 16 on its outer surface correspond to the fixing holes 18 on the front side of the mounting groove 9. By passing the fixing bolts 17 through the connecting holes 16 and threading them to the fixing holes 18, the circuit breaker body 8 can be firmly fixed in the mounting groove 9. The bolt connection method facilitates disassembly and replacement in the future.

[0026] The connection assembly 6 includes a connector 13 and a connector slot 14. The connector 13 is located inside the mounting slot 9, and the connector slot 14 is located on the back of the circuit breaker body 8. The connector 13 is adapted to the connector slot 14. The connector 13 is a conductive pin with an insulating shell, which connects to the external incoming and outgoing circuits. The connector slot 14 is provided with an elastic conductive sheet inside. When the circuit breaker body 8 is installed in the mounting slot 9, the connector 13 can be accurately inserted into the connector slot 14 to achieve circuit conduction. This design eliminates the need for manual wiring, which improves installation efficiency and avoids faults caused by wiring errors.

[0027] Mounting component 2 includes mounting plate 7, which is located on the back of protective housing 1. Multiple mounting holes 10 are provided on the outer surface of mounting plate 7. Mounting plate 7 is made of cold-rolled steel plate and is fixed to protective housing 1 by welding. The multiple mounting holes 10 on its outer surface are distributed at the four corners and can be fitted with expansion screws or bolts for fixing, meeting the needs of different installation scenarios.

[0028] The working principle of this utility model is as follows:

[0029] This novel circuit breaker device with metering function is first fixed to the distribution box or wall using expansion screws through the mounting holes 10 of the mounting component 2. Then, the external incoming and outgoing lines are connected to the circuit breaker body 8. Next, the circuit breaker body 8 is pushed in along the slide rail of the mounting groove 9, so that the connecting plug 13 is inserted into the connecting slot 14 and fixed with the fixing bolt 17. After the device is powered on, the metering module installed in the circuit breaker body 8 collects the power consumption data in real time and transmits it to the display screen 11 for display. When the circuit is overloaded or short-circuited, the circuit breaker body 8 quickly cuts off the circuit, and the warning light 12 lights up accordingly. Finally, if the circuit breaker body 8 needs to be replaced, simply unscrew the fixing bolt 17, pull out the old body along the slide rail, insert the new body and fix it. There is no need to disassemble the external wiring, making the operation efficient and cost-effective.
