Description

Technical Field

[0001] The utility model relates to the technical field of universal circuit breakers, in particular to a safe universal circuit breaker. Background Art

[0002] A circuit breaker is a switch device that can close, carry and disconnect the current under normal circuit conditions and close, carry and disconnect the current under abnormal circuit conditions within a specified time. Circuit breakers are divided into high-voltage circuit breakers and low-voltage circuit breakers according to their scope of use. The boundary between high and low voltage is relatively vague. Generally, those above 3kV are called high-voltage electrical appliances. Circuit breakers can be used to distribute electrical energy, start asynchronous motors infrequently, and protect power lines and motors. When they have serious overloads or short circuits and undervoltage faults, they can automatically cut off the circuit. Its function is equivalent to the combination of fuse switches and over-underheating relays. Moreover, it is generally not necessary to change parts after breaking the fault current. It has been widely used. Power distribution is an extremely important link in the generation, transmission and use of electricity. The power distribution system includes transformers and various high and low voltage electrical equipment, and low-voltage circuit breakers are a kind of electrical appliances with a large number of uses.

[0003] However, most existing circuit breakers require workers to manually push the opening and closing switches to perform opening and closing operations. When the circuit breaker has insulation damage or is used for a long time in a humid environment, leakage may occur. Since workers need to touch the circuit breaker when performing opening and closing operations, electric shock may occur, which reduces the safety of its use. Utility Model Content
