[0002] At present, the main switchboards of small and medium-sized ships mostly use frame-type air circuit breakers as the protection switch of the generator. When the power grid transmission or load distribution is unbalanced, the power transmission to the input terminal of the electrical equipment is prone to phase loss and overvoltage. or undervoltage and other abnormal power supply conditions, in order to ensure the normal operation of three-phase loads, current relays, voltage relays, time relays, thermal protection relays, phase loss protectors and leakage protectors are usually used to protect the three-phase loads from undervoltage and failure Overvoltage, overvoltage and phase loss protection, because the above method uses many low-voltage electrical components, the wiring is complicated, takes up a lot of panel installation space, and the function is still not perfect, and the versatility is not strong, which limits its popularization and use.

The invention discloses a three-phase multifunctional protector, which belongs to the field of electronic technology. A three-phase multifunctional protector, including a housing, a control assembly, an opening assembly, and a locking assembly; the invention is combined with a molded case air circuit breaker with high capacity to form a low-cost, small-volume, light-weight, high-performance Superior, it is a reasonable choice for ship design, manufacture and use departments. The present invention also installs the cover-opening assembly inside the casing, and utilizes the drive of the cover-opening assembly to control the opening and closing of the assembly, thereby facilitating the maintenance of the protection circuit inside the casing and the replacement of electronic components, thereby avoiding the traditional protector from being bulky and It is heavy and inconvenient to install in places with dense equipment. The present invention also installs a locking assembly on the front side of the housing, and the wires connected to current transformers, voltage transformers and other equipment can be locked by using the locking assembly, so as to avoid the vibration stress generated by the ship's navigation from causing the wires to break and ensure the safety of the present invention. normal operation.
