The quality of its state then directly affects its lightning protection effect, thus the safety of protected equipment is brought hidden danger.

Present stage SPD is generally of Thermal protection and two kinds of protection devices of overcurrent protection (internal or external), Thermal protection in use Device is used for protecting lightning protection component deterioration heating, and overcurrent protective device is used for the lightning protection device preventing transient over-current or overvoltage from causing Part puncture short, overcurrent protection simultaneously is as a kind of back-up protection mode of Thermal protection, so can act as in most of occasions Effective protective action.

But owing to conduction of heat is a relatively slow process, the sensitivity of thermel protection device is low, still may be used for slow temperature-rise period Play effective protection, but for low (in) in pressure system due to the steep temperature rise situation caused under sustained over voltage condition, heat Protection trip gear can not this process of perception in time and there is not action, cause lightning protection component breakdown, power current entrance SPD Circuit, when this power frequency electric flow valuve is not reaching to the initiation value of overcurrent protective device, overcurrent protective device also will not occur action, Thus cause SPD on fire；If selecting little by the initiation value of overcurrent protective device, though can start, but it is difficult to resist the impact of lightning current, SPD is caused cannot normally to release lightning current.There is serious action blind area in the overcurrent protective device of existing SPD and thermel protection device.

Prior art " the detection device of device of surge protector " (patent No.: 200910069431.2) and " a kind of surge guarantor Protect the on-Line Monitor Device of device " in (patent No.: 200910069594.0), it is proposed that two kinds are come by measuring electrodynamic mode The method of the state of detection device of surge protector.Wherein " the detection device of device of surge protector " (patent No.: 200910069431.2) propose metal spring leaf is arranged on device of surge protector side or is connected by wire, utilize pressure sensing The deformation of metal spring leaf measured by device, thus learns the state of device of surge protector, this method pressure transducer and metal spring leaf it Between without connect, measure inaccuracy, furthermore the mode of texturing of metal spring leaf is single, also makes the signal source of pressure sensor senses very Faint." on-Line Monitor Device of a kind of Surge Protector " (patent No.: 200910069594.0) proposes hardware and wave Gushing suppression device series connection, the shape of hardware is bending, when electric current is by surge suppression device and hardware, and electricity Stream makes the hardware of bending become straight effect, and consequent electric power passes through pressure sensor senses, and then learns electric current Information and the degradation of surge suppression device, this measuring method certainty of measurement is higher, but hardware is sealed in surge and lets out Put passage, the ability of the surge current of releasing on surge suppression device brought the biggest impact, cause Surge Protector residual voltage to raise, Reduce the level of protection to its claimed equipment.And, in these two prior aries, for the spy of electric power physical quantity Survey and be only limitted to understand the current information flowing through device of surge protector or surge suppression device, thus understand device of surge protector or surge The state of suppression device, to I am above-mentioned " overcurrent protective device of existing SPD and thermel protection device exist serious action blind area " Problem not do not solve, I am by being modified the deficiency of this electric power method of testing and innovate, so that it can interpolate that Current type in surge protector circuit, the power current that overcurrent protective device and thermel protection device exist action blind area is carried out Instant disjunction.

The thermel protection device of existing surge protector can not be grasped by user in time with the operating state of overcurrent protective device, simultaneously The use state of surge protector internal lighting protection element can not be known by user, thus results in and can not safeguard that surge is protected timely Protect device or change inner member or device, causing thunderbolt or other accidents.

In sum, there is serious action blind area in the overcurrent protective device of existing SPD and thermel protection device, and SPD is by this During the electric current in region, the SPD that thermel protection device and overcurrent protective device all can not damage departs from main circuit, thus occurs tight The potential safety hazard of weight；The working condition of the action situation of overcurrent protective device and thermel protection device and lightning protection component can not be by simultaneously User is learnt in time, brings serious potential safety hazard equally.

Summary of the invention

In order to effectively solve problem above of the prior art, the present invention proposes a kind of easy for installation and dependable performance, highly sensitive The Novel electric surge protector for power-supply system, the basic action blind area solving existing thermel protection device and overcurrent protective device and The working condition of overcurrent protective device, the action situation of thermel protection device and lightning protection component is unknowable, the potential safety hazard brought Problem.
