Description

Technical Field

[0001] The utility model relates to the technical field of air switches, in particular to a protection device for preventing misoperation. Background Art

[0002] Air switch, also known as air circuit breaker, is a type of circuit breaker. It is a switch that will automatically disconnect as long as the current in the circuit exceeds the rated current. Air switch is a very important electrical appliance in low-voltage distribution network and electric traction system. It integrates control and multiple protection functions. In addition to completing contact and disconnecting circuits, it can also protect circuits or electrical equipment from short circuits, severe overloads and undervoltages. It can also be used to start motors infrequently. Air switches are widely used in power supply systems in various places such as homes, factories, businesses and public facilities. The selection of air switches should be determined according to the rated voltage, rated current and required protection functions of the circuit. In actual applications, attention should also be paid to the installation and maintenance of air switches to ensure their normal operation.

[0003] Although the application of circuit breakers is very extensive, they still have some shortcomings. For example, they lack the ability to protect against misoperation. Since the circuit breaker operation button is exposed, it is easy to accidentally touch the operation button and misoperate the circuit breaker during normal installation or maintenance work. If a person misoperates or touches it by mistake, it may not only damage the equipment, but also cause personal injury to the staff. Therefore, a protection device against misoperation is proposed to address the above problems. Utility Model Content
