Description
TECHNICAL FIELD
[0001] The utility model relates to backup protection switch round type gap tripping technical field especially relates to backup protection switch round type gap tripping big device. BACKGROUND
[0002] Backup protection refers to the protection that is used to remove the fault when the main protection or circuit breaker refuses to act. When the circuit fails, the protection on the circuit will send a signal to disconnect the breaking element of the circuit in an instant. This immediate action protection is the main protection. When the main protection does not act due to various reasons, another protection will start and act to trip the fault circuit after a very short time delay. This protection is the backup protection. Multiple sets of protection can be provided for a circuit to ensure the safe operation of the circuit. For example, the Chinese utility model patent with the patent number CN203967742U proposes a surge protector with a fuse. The utility model improves the original surge protector with a fuse by changing its structure so that the current first enters the fuse module from the incoming line end in the surge protector, flows into the chip module through the thickened connecting copper sheet, and then flows out from the outgoing line end. The distance between the incoming line end, the fuse module, the chip module and the outgoing line end is shortened, thereby reducing the impedance and residual voltage when the current passes through. Moreover, when the current flowing through the surge protector is too large or the chip module is short-circuited due to thermal explosion caused by lightning strike, the fuse module can quickly disconnect the fault chip module from the power supply, eliminate the accident, and greatly improve the safety of the surge protector.
[0003] The above device still has some problems in use. When the device acts, it usually passes through a large current. When the large current breaks down the device, it will melt the connecting copper wire in the device, melt the welded solder joint, and even cause damage to some parts. However, the device is difficult to disassemble and maintain. Once damaged, the device must be replaced as a whole, which has high maintenance cost. UTILITY MODEL CONTENTS
