Description

Technical Field

[0001] This utility model relates to the field of energy-saving circuit breaker technology, and in particular to a dual-break energy-saving molded case circuit breaker with intelligent temperature control. Background Technology

[0002] A circuit breaker is a switching device that can close, carry, and interrupt current under normal circuit conditions and can close, carry, and interrupt current under abnormal circuit conditions within a specified time.

[0003] Circuit breakers can be used to distribute electrical energy, infrequently start asynchronous motors, and protect power lines and motors. They automatically disconnect the circuit when serious overloads, short circuits, or undervoltage faults occur, functioning similarly to a combination of a fuse switch and over / under-temperature relays. Furthermore, they generally do not require component replacement after interrupting a fault current. Currently available circuit breakers operate normally by controlling the opening and closing of the circuit through the interaction between the moving contact and the stationary contact.

[0004] Circuit breakers will develop towards "intelligent and digital" in the future. With the planning of Industry 4.0 and Made in China 2025, the digital trend of circuit breakers will become more and more obvious. Moreover, as the power grid's requirements for the performance and function of circuit breakers continue to increase, the performance of existing circuit breakers is gradually failing to meet market demands. Based on this, this application proposes a double-break energy-saving molded case circuit breaker with intelligent temperature control, which can solve the above problems. Utility Model Content

[0014] The present invention will be further described below with reference to the accompanying drawings, but the scope of protection of the present invention is not limited to the following description.

[0015] like Figures 1 to 4 As shown, a dual-break energy-saving molded case circuit breaker with intelligent temperature control includes a circuit breaker body 1. A through groove 7 is provided inside the rear side of the circuit breaker body 1. A U-shaped seat 2 is slidably installed inside the through groove 7. Temperature control components 3 are installed on both sides inside the U-shaped seat 2. A fixing post 9 is installed in the middle inside the U-shaped seat 2. A temperature control probe 4 is slidably installed outside the fixing post 9 and is electrically connected to the temperature control components 3. The temperature control probe 4 extends into the working space of the circuit breaker body 1.

[0016] As an optional technical solution of this utility model, the U-shaped base 2 has mounting slots 10 on both sides, and the temperature control component 3 is installed in the two mounting slots 10 respectively. This facilitates the installation of the temperature control component 3. At the same time, the temperature control component 3 can be selected according to the actual situation, and it works with the temperature control probe 4 to monitor the temperature inside the circuit breaker.

[0017] As an optional technical solution of this utility model, a spring 5 is sleeved on the outside of the fixing column 9, which is located behind the temperature control probe 4. Under the action of the spring 5, the temperature control probe 4 can always be in the extended state so that it can be inserted into the circuit breaker.

[0018] As an optional technical solution of this utility model, guide seats 8 are installed on both sides of the inner wall of the through groove 7, and guide grooves 11 are opened on both sides of the closed side of the U-shaped seat 2. One end of the guide groove 11 is closed and the other end is open. The two guide grooves 11 are respectively slidably engaged with the two guide seats 8. This makes it easy to combine the U-shaped seat 2 with the circuit breaker body 1. The size of the U-shaped seat 2 needs to be adapted to the internal size of the through groove 7 to ensure that the U-shaped seat 2 can seal the through groove 7. In order to ensure a good sealing effect of the U-shaped seat 2 on the through groove 7, a sealing element can be added to the U-shaped seat 2.

[0019] As an optional technical solution of this utility model, the closed ends of the two guide grooves 11 are provided with mounting holes 12, and locking parts 6 are threadedly installed in the two mounting holes 12, which are respectively threaded with the two guide seats 8. In this way, the position of the U-shaped seat 2 can be fixed by the locking parts 6 to prevent the U-shaped seat 2 from loosening.

[0020] In summary, the features, assembly method, usage process, and functions of each component in this utility model are as follows: A through groove 7 is provided on the rear side of the circuit breaker body 1, and a U-shaped seat 2 is slidably installed inside it. A temperature control component 3 is installed inside the U-shaped seat 2. A fixing post 9 is installed in the middle of the U-shaped seat 2, and a temperature control probe 4 is slidably installed on it. The temperature control probe 4 is electrically connected to the temperature control component 3. In use, the U-shaped seat 2 is placed into the through groove 7 so that the temperature control probe 4 contacts the component of the circuit breaker body 1, and it monitors the internal temperature of the circuit breaker body 1 to prevent the circuit breaker temperature from becoming too high and affecting normal use.
