Description

Technical Field

[0001] The utility model relates to the technical field of circuit breakers, in particular to a leakage indicating mechanism for circuit breakers. Background Art

[0002] Small circuit breakers, also known as miniature circuit breakers, are suitable for overload and short-circuit protection of AC 50 / 60Hz rated voltage 230 / 400V, rated current not exceeding 125A lines. They can also be used for infrequent line operation conversion under normal circumstances. Small circuit breakers are mainly used in various places such as industry, commerce, high-rise and residential buildings. Small leakage circuit breakers are switches that can automatically operate when the leakage current in the circuit exceeds a predetermined value, which can protect the safety of people and electrical appliances.

[0003] In the disclosure of the Chinese utility model patent application publication specification CN209708919U, the leakage indication mechanism and circuit breaker for circuit breakers are disclosed. Although in the second position of the indicator, the indicating part of the indicator is pressed to overcome the elastic force of the second elastic member to move the indicator to the first position, at this time, the engaging part of the indicator moves from the groove into another groove, and the moving iron core returns to the initial position under the action of the first elastic member, but during use, due to the high demand for household electricity, multiple circuit breakers are often set for protection work, which easily leads to a large amount of heat accumulation at the connection of the circuit breaker, which is difficult to dissipate heat, and thus easily leads to damage to the circuit breaker, resulting in certain economic losses. When the circuit breaker alarms, it is necessary to close several circuit breakers one by one, otherwise it is easy to cause workers to be electrocuted when repairing the line, causing certain safety hazards, and greatly affecting the workers' maintenance efficiency. Therefore, a leakage indication mechanism for circuit breakers is proposed to solve this problem. Utility Model Content
