Description
Technical field
The present invention relates to a kind of novel surge protective device, belong to the carrying out surge protection technical field of electronic electric equipment.
Background technology
The line surge protection that a variety of causes such as thunder and lightning causes causes the major reason that electronic electric equipment is aging or damage, and it is one of taked important safeguard procedures that the metallic circuit such as power line, holding wire, control line of electronic electric equipment is installed Surge Protector.In this technical field; current Problems existing is: Surge Protector is while proterctive equipment; himself device can gradually deterioration or directly damage under excessive surge impact; switching device then can produce afterflow; all have a strong impact on the normal work of equipment or system; especially device failure causes the situation of short circuit even more serious, now should be departed from circuit in time, otherwise just there will be the phenomenons such as burning, switch trip, power failure, Signal transmissions fault.
Current solution to the problems described above is connect on the circuit being provided with Surge Protector independently circuit breaker or a fuse, as the backup protection of Surge Protector.There are the following problems for this method: series trip device or fuse on Surge Protector circuit, takes up room large, cause insufficient space; The various coiling of connection line, circuit induction reactance strengthens, and causes the Surge Protector response time slack-off, and equipment end residual voltage raises, and overall surge protection effect is declined.
And because user does not know the current state of each Surge Protector, the lightning protection safety of electronic information just becomes unknowable thing.And for those equipment to thunder and lightning sensitivity; this can't stand especially; so caused the demand that user is urgent: one is to know whether each Surge Protector is now also playing due protective effect in time; if not; then should change immediately: two is the situations will knowing that Surge Protector has been struck by lightning; that is, Surge Protector be predicted and whether soon lost efficacy, to safeguard in advance.
The existing technical method shortcoming that solves the problem at present is as follows:
One, the method that Surge Protector is regularly detected generally is adopted; to detect before and after thunderstorm season generally every year, but this method usually can not play a role, this is because after making regular check on; possible Surge Protector is just broken by thunder and lightning at once, and follow-up thunderbolt will smash equipment.In addition, for the Surge Protector be installed in signal circuit, interrupt signal can not be shut down, even if so periodic detection can not be effective.
Two, at the sensitive switch that power source surge protector inside arranges thermal release device and is connected with it, export a switching value when cause thermal damage occurred power source surge protector, reported to the police by the fault of this switching value to Surge Protector.This method Problems existing has:
1, device of surge protector deterioration or damage may not produce the energy being enough to make trip gear action, and at this moment alarm unit can not carry out warning output.
2, device failure just possibility output alarm signal, can not predict in advance, unknowable to the state in its damage process.
3, class signal Surge Protector is not suitable for.
Three, get involved Surge Protector circuit with electronic device to detect.Its defect is: measuring circuit itself there occurs with Surge Protector circuit and is electrically connected, and causes measuring circuit by lightning surge premature degradation.
Four, series trip device or fuse on Surge Protector circuit, takes up room large, the various coiling of connection line, and circuit induction reactance strengthens, and makes its response time slack-off, and circuit two ends residual voltage raises, and causes overall surge protection effect to decline.
Summary of the invention
In order to effectively solve the above prior-art problems, the present invention proposes a kind of novel surge protective device.
The object of this invention is to provide a kind of novel surge protective device, short circuit protection module grafting or be crimped on base, short circuit protection module is connected with surge suppression device, and both are integrated in one by base.When surge suppression device deterioration or when damaging, short circuit protection module to controller, is disconnected by controller by light-metering unit by signal converting transmission, so the surge suppression device that may break down just spins off from circuit.
The present invention realizes by the following technical solutions: Surge Protector of the present invention, forms primarily of surge suppression device, light-metering unit, signal converting transmission unit, control unit, short circuit protection module, base and shell.Light-metering unit is just installed surge suppression device, and light-metering unit is connected with signal converting transmission unit, and control unit is connected with signal converting transmission unit, and short circuit protection module is connected with control unit.
Described surge suppression device is surge suppression device that can be luminous when conducting, is connected with connected in electrical series between described short circuit protection module.
Described light-metering unit is just installed surge suppression device, with surge suppression device electrically not conducting.
Described signal converting transmission unit comprises A/D change-over circuit and circuit for transmitting digital signals.
Described control unit can be microprocessor or single-chip microcomputer.
Described short circuit protection module comprises short-circuit protection device, shell, electrical connector.
Described short circuit protection module can be fuse or short-circuiting device or relay.
The invention has the advantages that:
1, decrease length and the induction reactance of connection line, therefore improve integral protection performance; The protection of the various circuits such as power supply, signal, control can be applied to.
2, can grasp the situation that device of surge protector had suffered to be struck by lightning in time, thus whether precognition Surge Protector soon lost efficacy, to carry out maintenance work in advance, solving existing detection method only could the difficult problem of output alarm signal after device failure.
3, measuring unit adopts light measuring method; itself with Surge Protector circuit without being electrically connected; avoid measuring unit by the problem of lightning surge premature deterioration, the intervention that it also avoid measuring circuit makes the work of class signal Surge Protector occur new loss of signal and the problem of fault point.
4, transform transmission unit by signal and carry out necessary process or conversion to the information parameter after collection, making to transmit rear data accuracy increases, and is conducive to next step analyzing and processing.
5, can the reason of state in real time in detection record surge suppression device damage process and damage, for lightning protection provides full and accurate data message.
