Description

Technical Field

[0001] The utility model relates to the technical field of electrical safety protection equipment, in particular to a surge protector. Background Art

[0002] Surge protector is a widely used electrical safety protection device. Its function is to limit overvoltage and discharge surge current, thereby providing safety protection for various electronic equipment, instruments and meters, and communication lines.

[0003] Surge protectors are usually connected in parallel with the equipment being protected. For ease of maintenance, workers usually connect a fuse in series above the surge protector. When the power distribution system is struck by lightning, the button in the trip window of the surge protector will pop out, reminding the worker that the surge protector needs to be replaced. When replacing the surge protector, the surge protector can be replaced by disconnecting it from the power supply through the fuse, thus avoiding power outages caused by disconnecting the main switch, and when encountering a short circuit with high current, the surge protector can be disconnected from the main circuit through the fuse, so as not to affect the normal operation of other equipment.

[0004] However, in actual power distribution operations, many workers mistakenly use circuit breakers in series with surge protectors. Although circuit breakers can disconnect circuits more conveniently, they can easily trip due to the impact of lightning current, causing the surge protector to be cut off, making it unable to play a protective role. In addition, after the power distribution system is struck by lightning, workers tend to ignore the pop-up of the button in the trip window of the surge protector, thereby blindly supplying power to the circuit, causing damage to electrical components. Utility Model Content

[0010] A further improvement of the utility model is that the buzzer alarm is an "L"-shaped structure as a whole, and the buzzer alarm is arranged above the surge protector module so that the top of the surge protector module can be placed in the opening of the buzzer alarm.

[0011] A further improvement of the utility model is that a clamping block is provided on the buzzer alarm, and a clamping groove corresponding to the clamping block is opened on the protector base above the surge protector module, and the protector base and the buzzer alarm are clamped together through the clamping groove and the clamping block.

[0012] A further improvement of the utility model is that the clamping block and the clamping groove are T-shaped structures corresponding to each other.

[0013] A further improvement of the utility model is that the tripping window is arranged on the top of the surge protector module, and the touch switch is arranged on the opening side wall of the buzzer alarm at a position corresponding to the tripping window.

[0014] A further improvement of the utility model is that a sound amplification port is arranged at the top of the buzzer alarm.
