Problems solved by technology

The tripping structure of some existing surge protectors has a single tripping position. If the tripping structure fails, the leakage current will increase, resulting in protection failure. The increase in leakage current may even cause the power supply to short-circuit and catch fire.

Abstract

The invention discloses an arc-avoiding surge protection device with multiple insurances, which includes an inner shell, an outer shell, an arc-proof component, a voltage sensitive component, an electrode lead-out pin and a response switch component; the inner shell is provided with two electrodes hole, two track platforms and a partition wall; the arc protection assembly includes four elastic elements and two separators; the voltage sensitive assembly includes more than one voltage sensitive element; the response switch assembly includes two A separate electrode, a heat sensitive element, a first electrode and a second electrode; the invention is used to suppress the instantaneous overvoltage and overcurrent in the circuit, and when the voltage sensitive component continues to heat up due to a fault short circuit, the response switch component prompts the action of the arc protection component to separate , to prevent the short-circuit overload caused by the electric breakdown caused by the arc generated when the switch is ejected and separated, and set up multiple fusing separation points, multiple insurances, effectively avoiding fire hazards.

Description

technical field [0001] The invention relates to a circuit protection device, in particular to an arc-avoiding surge protection device with multiple insurances. Background technique [0002] Surge protectors are suitable for power supply systems or communication systems to protect against indirect lightning and direct lightning effects or other instantaneous overvoltage surges, and are suitable for family residences, tertiary industries and industrial fields. Surge protection has protection modes such as phase-to-phase, phase-to-ground, neutral-to-neutral, neutral-to-ground and combinations thereof. Surge protector is an indispensable device in lightning protection of electronic equipment, and it used to be called "lightning arrester". 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 discharge the powerful lightning c...
