Mainly by two classes, there is in the market the signal Surge Protector of life-span monitoring function: a class is contactless on-line monitoring, its feature is mainly ID and the state that using radio frequency recognizing technique is determined protector, and its shortcoming has and do not have remote signaling function, circuit complicated, high in cost of production defect; Another kind of is that leakage current and discharge time by detection signal Surge Protector carries out early warning to its life-span; it adopts internal cell power supply, and major defect is: cost is high, can not indicate exactly the state of protector; and do not there is remote signaling function, not environmental protection of the utmost point yet.
Utility model content
Technical problem to be solved in the utility model is to provide a kind of signal Surge Protector with Indication of Losing Efficacy and remote signaling function, is intended to solve the state that existing signal Surge Protector can not be indicated protective circuit exactly.
The utility model is achieved in that a kind of signal Surge Protector with Indication of Losing Efficacy and remote signaling function, comprises surging protection circuit and condition indication circuit;
Described condition indication circuit is pressed close to described surging protection circuit, and when described surging protection circuit excess Temperature, described condition indication circuit automatic shutdown circuit also provides Indication of Losing Efficacy and output remote signals.
Further, described surging protection circuit comprises some protective elements, lightning protection component and decoupling component; Described protective element, described lightning protection component and described decoupling component are connected in series and form series loop.
Further, described condition indication circuit comprises some Thermal Cutoffs, indicator light and supply socket; Described Thermal Cutoffs, described indicator light are in series and are connected with described supply socket.
Further, described condition indication circuit also comprises relay, and described relay road is in parallel and is connected with described indicator light, thereby makes condition indication circuit output remote signals for adhesive or open circuit.
Further, described condition indication circuit also comprises optocoupler, and described optocoupler is in series and is connected with described supply socket with described Thermal Cutoffs, described indicator light, thereby makes condition indication circuit output remote signals for one-way conduction or open circuit.
Further, described Thermal Cutoffs and surging protection circuit are close together.
Compared with prior art, beneficial effect is the utility model: the described signal Surge Protector with Indication of Losing Efficacy and remote signaling function can not only be indicated the quality of surging protection circuit exactly, also has long-range remote signaling function.
Accompanying drawing explanation
Fig. 1 is that the utility model signal Surge Protector is exported dry contact as the embodiment schematic diagram of remote signalling with relay;
Fig. 2 is that the utility model signal Surge Protector is exported single-way switch signal as the embodiment schematic diagram of remote signalling with optocoupler.
Embodiment
In order to make the purpose of this utility model, technical scheme and advantage clearer, below in conjunction with drawings and Examples, the utility model is further elaborated.Should be appreciated that specific embodiment described herein is only in order to explain the utility model, and be not used in restriction the utility model.
The signal Surge Protector with Indication of Losing Efficacy and remote signaling function described in the utility model is avoided Lightning Over-voltage, switching overvoltage and device interior overvoltage for the protection of device signal port; and there is state indication and long-range remote signaling function, provide dry contact and optocoupler two kinds of remote signalling modes simultaneously.
As shown in Figure 1 and Figure 2, a kind of signal Surge Protector with Indication of Losing Efficacy and remote signaling function, comprises surging protection circuit 100 and condition indication circuit 200.Described condition indication circuit 200 is pressed close to described surging protection circuit 100, and when described surging protection circuit 100 excess Temperature, described condition indication circuit 200 automatic shutdown circuits also provide Indication of Losing Efficacy and output remote signals.
Combine with above-described embodiment, described surging protection circuit 100 comprises some protective elements 101, lightning protection component 103 and decoupling component 102.Described protective element 101, described lightning protection component 103 and described decoupling component 102 are connected in series and form series loop.Described surging protection circuit 100 is by gas discharge tube, resistance, transient voltage suppressor diode, piezo-resistance, solid discharging tube, thermistor and their various forms of combinations.The form that is described surging protection circuit 100 can have: gas discharge tube, gas discharge tube add decoupling resistance, gas discharge tube and add decoupling resistance and add transient voltage suppressor diode, gas discharge tube and add piezo-resistance or gas discharge tube and add the resistance compound modes such as quick resistance of pressurizeing.
Described condition indication circuit 200 comprises some Thermal Cutoffs 201, indicator light 202 and supply socket 204.Described Thermal Cutoffs 201, described indicator light 202 are in series and are connected with described supply socket 204.
Combine with above-described embodiment, a kind of embodiment of condition indication circuit 200 is that as shown in Figure 1, described condition indication circuit 200 also comprises relay 203.By one or more Thermal Cutoffs 201, relay 203 and supply socket 204, be in series and connected and composed loop, indicator light 202 is in parallel with relay 203.Together with Thermal Cutoffs 201 and protective element 101 in surging protection circuit 100 and decoupling component 102 fit tightly.
