Description

Technical Field

[0001] The utility model mainly relates to the technical field of circuit breakers, in particular to a combined leakage protection circuit breaker. Background Art

[0002] The leakage protection circuit breaker is mainly used to protect the equipment from leakage faults and personal electric shock with fatal danger. It has overload and short-circuit protection functions, which can be used to protect the line from overload and short circuit. It can also be used as an infrequent switching start of the line under normal circumstances. Most of the existing leakage protectors are used in series with air switches. When connected in series, it is often necessary to select multiple leakage protectors for use due to the large number of switches.

[0003] For example, the utility model patent with application number: CN216015224U discloses a combined leakage protection circuit breaker, including a neutral wire junction box, a side wall at one end of the neutral wire junction box is movably connected to a live wire junction box, and the other side wall of the neutral wire junction box is movably connected to a fixed shell, and both the neutral wire junction box and the live wire junction box are provided with a closing and opening handle. The utility model sets an independent neutral wire junction box and a live wire junction box, uses a cylindrical slide groove and a cylindrical slide rod to clamp and position the neutral wire junction box and the live wire junction box, and then uses screws and threaded holes to tightly fix the neutral wire junction box and the live wire junction box together. It is not only easy to assemble, but also can be replaced independently when the neutral wire junction box or the live wire junction box is damaged, which is convenient for maintenance and reduces maintenance costs. At the same time, by setting an audible and visual alarm, when the closing and opening handle is tripped, the insulating plug is driven by the ribbon to leave the slot, so that the audible and visual alarm is triggered, which is convenient for personnel to repair the faulty circuit in time.

[0004] The inventor believes that although the above device has the advantage of being convenient for personnel to repair faulty circuits in a timely manner, in actual use, multiple adjacent devices cannot be spliced ​​together. When there are too many switches, multiple devices can only be installed by themselves for use, which has certain limitations in use. At the same time, the device is relatively inconvenient to disassemble and assemble as a whole. Utility Model Content
