An anti-misoperation device combining a circuit breaker and a surge protector in series

Abstract

The invention discloses an anti-misoperation device for series combination of a breaker and a surge protection device. The anti-misoperation device comprises the breaker and the surge protection device. The lower outgoing line end of the breaker is electrically connected with the upper incoming line end of the surge protection device. The surge protection device comprises a base and a plugin, wherein the plugin is inserted in the base; a telescopic baffle is arranged on the lower portion of the breaker and is connected with a manual combination and separation operating mechanism of the breaker in a linkage mode; when the manual combination and separation operating mechanism of the breaker is in a closing state, the telescopic baffle stretches out, and the bottom end of the telescopic baffle is lower than the top end of the plugin; when the manual combination and separation operating mechanism of the breaker is in an opening state, the telescopic baffle retracts, and the bottom end of the telescopic baffle is higher than the top end of the plugin. The anti-misoperation device can prevent electric shock accidents and load faults from occurring, and is simple in structure, high in reliability and safe and convenient to use.

Description

technical field [0001] The invention relates to a surge protector, in particular to an anti-misoperation device in which a circuit breaker and a surge protector are combined in series. Background technique [0002] Surge protection device (Surge protection Device) is an indispensable device in the lightning protection of electronic equipment. It used to be called "lightning arrester" or "overvoltage protector". The English abbreviation is SPD. The function of the surge protector is to limit the instantaneous overvoltage that enters the power line and signal transmission line within the voltage range that the equipment or system can withstand, or to leak the powerful lightning current into the ground, so as to protect the protected equipment or system from being damaged. Damaged by impact. Overvoltage will cause direct damage to circuits and components in electrical or electronic devices. Surge protector (also known as surge protector) is an important protection device to l...

AI Technical Summary

Problems solved by technology

The circuit breaker is connected in series with the above two surge protectors. Usually, the circuit breaker and the base of the surge protector are combined and installed in series. When replacing the surge protector, the circuit breaker needs to be in the off state. The operating mechanism is prone to disassembly and replacement of the surge protector when the circuit breaker is on. At this time, the incoming terminal of the surge protector is still charged, and electric shock accidents and load failures are prone to occur.
