Description

Technical Field

[0001] This utility model relates to the field of mining electronic equipment, and in particular to a mining control circuit breaker. Background Technology

[0002] In the mining industry, mining control circuit breakers are one of the core devices ensuring the safe and stable operation of the power system. They bear the critical responsibility of controlling the connection and disconnection of circuits and quickly cutting off circuits in case of overload, short circuits, or other abnormal conditions. In daily mining operations, numerous electrical devices, such as mining equipment, hoisting equipment, and ventilation equipment, rely on mining control circuit breakers for precise power control. Through their accurate control of current, they ensure that each piece of equipment operates normally under rated voltage and current conditions, greatly improving the safety and efficiency of mining operations. For example, in the event of a short circuit, the mining control circuit breaker can instantly cut off the circuit, preventing electrical fires or damage to expensive electrical equipment caused by excessive current, ensuring the safety of personnel and equipment, and maintaining the orderly progress of mining production.

[0003] Existing mining control circuit breakers have many problems in dealing with the complex environment of mines. The high humidity in the mining environment can easily cause the electrical components inside the circuit breaker to become damp, leading to a decrease in insulation performance and increasing the risk of leakage and short circuits. A large amount of dust can enter the circuit breaker and accumulate in key parts such as contacts and transmission components, affecting their normal contact and operation, leading to poor contact, overheating, or even malfunction. Corrosive gases can gradually erode the metal parts and circuit boards of the circuit breaker, reducing its mechanical strength and electrical performance, and shortening the service life of the equipment. Therefore, a mining control circuit breaker is proposed. Utility Model Content

[0004] The purpose of this invention is to provide a mining control circuit breaker to solve the aforementioned problems, addressing numerous issues that existing mining control circuit breakers face when dealing with the complex environment of mines. The high humidity in the mining environment easily causes moisture to accumulate in the electrical components inside the circuit breaker, leading to decreased insulation performance and increasing the risk of leakage and short circuits. Large amounts of dust can enter the circuit breaker and accumulate in critical parts such as contacts and transmission components, affecting normal contact and operation, resulting in poor contact, overheating, or even malfunction. Corrosive gases can gradually erode the metal parts and circuit boards of the circuit breaker, reducing its mechanical strength and electrical performance, and shortening the equipment's service life.
