Technical field
The present invention relates to surge protector, relate in particular to a kind of by the self-monitoring surge protector of parameter setting.
Background technology
(Surge Protective Device is in order to a kind of equipment of restriction transient overvoltage and guiding surge current SPD) to surge protector, which comprises at least a kind of non-linear element.Because it not only possesses the function that lightning protection is arranged, but also have the superpotential effect of inhibition, so SPD is widely used in a lot of fields, such as the meteorological disaster field.When surge occurring, the characteristic of SPD by self limiting transient overvoltage and dividing to walk the surge electric current will will be limited in below the withstand voltage of equipment from the transient overvoltage that circuit is come in, thus the purpose of the equipment that is protected.But when surge voltage surpassed the maximum bearing ability of SPD design and capacity discharge current, SPD may lose efficacy or be damaged, and therefore need replace the SPD of inefficacy before next surge arrives.Yet, when SPD is in open loop failure mode, be to be difficult to find that SPD lost efficacy, the no longer shielded consequence of protected equipment appears thus; What is more, when SPD was in short circuit or low-impedance failure mode, normal working power can cause the SPD heating of losing efficacy by the SPD that had lost efficacy, if untimely cutting off the electricity supply causes that fire etc. causes the incident of heavy losses to take place to people's life and property.Therefore, in the use of SPD, need monitor,, and when SPD lost efficacy, can in time handle so that understand the operating state of SPD to SPD.
At present, the method for supervising that SPD is commonly used mainly contains following several:
First kind of method for supervising be by professional monitor staff to on-the-spot, dismounting SPD measures, to determine whether SPD needs to change.This method for supervising needs SPD to quit work to cut off the power supply measurement, not only waste time and energy and also efficient very low, the most important thing is, in the outage measuring process, bring disadvantageous consequence then can for protected setting if surge occurs.
Second kind of method for supervising be by the attendant to on-the-spot, check by visual or special-purpose monitoring equipment whether SPD exists damage.Special-purpose monitoring equipment is very expensive, and the cost of monitoring is very high, and therefore, whether most of attendants can only exist visible damage by the visual SPD of inspection, can not understand the operating state of SPD more, are easy to occur checking the situation of makeing mistakes.
Above-mentioned two kinds of methods if the gap periods of monitoring is long, then occurs SPD easily and damage and not timely situation about finding, if the monitoring gap periods is short, the human cost that need drop into will increase, and then increase the monitoring cost of SPD.
The third method for supervising is to check that by special laying circuit monitors SPD, when taking place as the thread off module indication window that causes of SPD is jumped redly when waiting mechanical destruction, checks that link tester crosses the warning device that activates in the control room and reach the purpose of monitoring SPD.This method for supervising needs special the laying to check circuit, and cost is expensive and construction is complicated, and many control rooms are the machine rooms of unattended duty, and this method for supervising just can not be suitable for.
China Intellectual Property Office on July 20th, 2005 disclose that application number is 200510006002.2, the applying date is a kind of surge protector with prior-warning device on January 2nd, 2005.This SPD comprises the SPD body, and SPD body end of incoming cables is every to be provided with a zero-sequence transformer mutually, and zero-sequence transformer connects integrated circuit, and integrated circuit connects LCD, and integrated circuit also connects the circuit breaker tripping device.It can inform which phase piezo-resistance of user is damaged and the thunderbolt number of times.The attendant also can reach the purpose of monitoring SPD by the SPD that uses foregoing invention.
In sum, there is following defective in existing SPD:
At first, can't accomplish SPD is monitored in real time, understand the operating state of SPD in real time.Such as, when SPD thread off wait until the self-protection mechanism action after, can only arrive and find just now in making regular check on next time, if surge occurred before making regular check on next time, the accident of the damage equipment that causes easily being struck by lightning.
Secondly, can't predict and understand the operating state of SPD, whether SPD has damaged etc. and to have had no way of also can't understanding when arriving for surges such as a certain thunderbolts, insurance company does not have reliable foundation for the compensation of this type of insurance kind, at present only can be qualitative the understanding accident whether information such as thunderbolt took place the same day, and can not recognize the state of SPD when thunderbolt takes place, and for example whether online, whether thread off etc.
At last, taking place when unusual even monitor SPD, also is to need the special messenger to on-the-spot it to be changed or in time cut off the power supply of SPD.This (is not easy to change or have little time replacing as SPD) under some emergencies or special state, SPD initiatively cutoff circuit avoid fire to take place.

Below the working condition of SPD when just introducing signal picker respectively and adopting temperature sensor, current monitor and voltage monitor.
1) about temperature sensor, signal converter and active tripper:
Prior art is not done monitoring or is adopted the low temperature welding, changes by the fusing point temperature sensor of welding with scolding tin, finishes the solder joint action of cutting off the electricity supply by mechanical devices such as springs.Its shortcoming is 1〉fusing point of scolding tin and unstable, delay of response; 2〉the mechanical mechanism easy deformation is aging, and the thunderbolt energy is very huge, sees mechanical destruction more, in case mechanical destruction such as deform, the solder joint release mechanism just performs practically no function; 3〉influenced by environmental temperature; 4〉heat generating spot needs heat-transfer device to bump, can not really respond to the actual state of nonlinear device body.
Processor real-time is gathered the scene temperature of nonlinear device heating part among the present invention by temperature sensor, preserve by storing in the memory cell after the signal converter conversion, do contrast with default temperature threshold simultaneously, surpass alarm points in case find temperature, then control field alert and report to the police, and alarm signal is delivered to communication interface; Cause at the unattended duty state or because of other reasons under the situation that temperature continue to raise, may cause the limit of igniting in case temperature is elevated to, processor is controlled active tripper and is cut off the electricity supply, and the situation that prevents further worsens.
2) current monitor, signal converter and active tripper:
Prior art is not done real-time monitoring, generally is during by every year or season routine inspection, by special test equipment SPD is lifted down from circuit and carries out static test, and whether perhaps monitor by induction coil has lightning current to pass through.Shortcoming: 1〉can't understand the operating state of nonlinear device in real time, particularly at the tours of inspection device, the nonlinear device incident that is damaged probably, and cause that the front describes possible disaster (referring to that lightning protection function lost efficacy or disaster hidden-trouble); 2〉SPD is lifted down test from circuit, can not really understand the online dynamical state of SPD, may take place just to monitor qualified product, approaching inefficacy the under the dynamic operating condition of connection line through static state; 3〉to enough auxiliary improvement lightning protection scheme and supports that follow-up insurance responsibility is screened of the record of lightning current number of times.
The present invention crosses the leakage current or the thunder-strike current of nonlinear device by the current sensor acquisition stream by middle processor real-time, preserve by storing in the memory cell after the signal converter analog-to-digital conversion, do contrast with default leakage current threshold value simultaneously, surpass alarm points in case find leakage current, then control field alert and report to the police, and alarm signal is delivered to communication interface; Cause leakage current to continue under the situation of rising at the unattended duty state or because of other reasons; in case leakage current is elevated to the limit that may cause surge protector to lose efficacy and ignite; the active tripper of processor may command is cut off the electricity supply, and the situation that prevents further worsens.
3) voltage monitor, signal converter and active tripper:
Prior art is not done monitoring.
The present invention is applied to the voltage (normal working voltage or surge voltage) at nonlinear device two ends by the voltage sensor collection by middle processor real-time, preserve by storing in the memory cell after the signal converter analog-to-digital conversion, allow operating voltage Uc threshold value to do contrast with default maximum simultaneously, surpass Uc in case find voltage, then control field alert and report to the police, and alarm signal is delivered to communication interface.Voltage indexes is as the parameter of active tripper action generally speaking, can be used as analysiss protection such as insurance company and loses efficacy that to come from that voltage exceeds standard still be the foundation of surge voltage.But under some specific situations, also can be set by the user an absolute rating and control active tripper by processor and cut off the electricity supply, the situation that prevents further worsens.
See also Fig. 4, it is the flow chart of the self-monitoring method of a kind of surge protector.It may further comprise the steps:
S110: gather the operating state data that shows surge protector body operating state in real time; When thunderbolt or other surges generation, the SPD body is in low resistive state and big electric current occurs on the circuit simultaneously, and big electric current triggers processor and interrupts counting after the overcoupling transformation; At this moment, can look different requirements, can write down real-time time, lightning surge size of current or above-mentioned whole state parameter and store in the memory cell.
S120: operating state data and canonical parameter or the preset value preserved are in advance compared, and make the action of output alarm and/or this body running of control SPD according to comparing result.
Step S120 further comprises:
Comparing result shows when surge protector enters unusual condition; preservation shows the operating state data of current surge protector bulk state, and sends warning message or export warning message to external equipment by output device output or communication interface by warning device.
Step S120 further comprises:
Comparing result shows that surge protector has entered fatal type when unusual; according to active tripper enable decision be set whether carry out ACTIVE CONTROL; if do not allow to carry out ACTIVE CONTROL, then send danger warning, otherwise control SPD disconnects from electric power loop or signal circuit.
Below just the present invention is described with an example.
After surge protector powers up beginning, at first judge whether be power up first (step 11), if, time of powering up for the first time of record (step 12), and carry out step 14, otherwise record powers up number of times, and (step 13) carry out step 14 then;
Step 14, the canonical parameter in the reading cells is finished the initialization setting of various functions.
Step 15, under the control of processor, sampling shows the operating state data of SPD body operating state, and the record operating time;
Step 16: the various threshold values of operating state data with storage are in advance compared respectively, judge whether SPD enters abnormality, otherwise, then enter step 18, otherwise normal show (step 17) enters step 15;
Step 18: note down unusual operating state data, and output alarm information is to display and communication interface (step 19).Detecting the SPD body when unusual, also can adopt repeatedly repeated authentication result's method to avoid false alarm;
Step 20: judge further whether exceptional value goes beyond the limit of setting, unusually whether promptly described is that fatal type is unusual, if then enter step 22, otherwise dangerous show (step 21) closed in alarm indication;
Step 22: judge whether to allow ACTIVE CONTROL, if then send danger warning, otherwise control SPD disconnects (step 24) from electric power loop or signal circuit; Otherwise, send hydropac.
In this process, processor also needs to receive the interruption that accident takes place, such as, thunderbolt etc. also have to take place and interrupts in the interruption controls of keyboard interrupt, external equipment, when processor receives interrupt requests, at first judge whether to interrupt, in this way, then note down surge or thunderbolt operating state data for surge.If not, then will carry out the control command of keyboard or external equipment.
More than disclosed only be several specific embodiment of the present invention, but the present invention is not limited thereto, any variation of having carried out no creative work on basis of the present invention all should drop in protection scope of the present invention.
