The early stage main core of votage limit type lightning protection device is piezo-resistance substrate and version thereof, and lightning current is a probability event, and piezo-resistance is after repeatedly being struck by lightning; Its performance degradation, lightning protection properties disappears, and leakage current can increase rapidly; The product pressure sensitive voltage that has descends; The then rising that has, thus the piezo-resistance heating produces a temperature rise Δ t1; When circuit generation sustained overvoltage (becoming 380V), also can produce big leakage current greatly on the other hand, cause the heating of piezo-resistance temperature like 220V; Produce temperature rise Δ t2, this leakage current that is maybe be less than the operating current of circuit breaker, and circuit breaker can not move; The piezo-resistance persistent fever, lightning protection device will produce coking because of long-pending heat, even blast naturally; On fire, a series of accidents such as burning equipment are so be all the more to seem important and necessary for the Failure Alarm of lightning protection device.
Summary of the invention
The utility model technical problem to be solved is exactly to provide a kind of safe and reliable pressure limiting can plug deterioration display power supply lightning protection device for the defective that overcomes above-mentioned prior art existence.
The purpose of the utility model can realize through following technical scheme: pressure limiting can plug deterioration display power supply lightning protection device, it is characterized in that, comprises protection module, base and is used for and the loop that is connected by protection equipment; Described protection module comprises red module housing, flap, piezo-resistance, copper sheet and spring; Described module housing is provided with a window, is provided with one in this module housing, and the neck of described flap is sheathed on the axle; Its underpart is provided with a projection; Its afterbody one side is provided with a green direction board over against window, and described copper sheet is sheathed on the projection and with the loop and is connected, and the one of which end is through the pin L1 welding of low temperature welding wire and piezo-resistance; The pin L2 of this piezo-resistance is connected with the loop, and the two ends of described spring stretch and are fixed on flap afterbody and the module housing.
The utility model also comprises the signal output mechanism; Described signal output mechanism comprises transmission button, sensitive switch and signal output terminal; The head end of described flap is in transmission connection through transmission button and sensitive switch, and described sensitive switch is connected with the signal output part subsignal.
Product is installed on the 35mm guide rail easily, and protection module can carry out deterioration and show, and can conveniently plug replacing.
Compared with prior art, the utlity model has following advantage:
1, current in the lightning protection device industry, the discharging current of lightning protection for power supply is generally less than normal, and the utility model product discharging current can reach 65KA, can both play a very good protection for the induction thunder;
2, adopt the structure of hot dropout protective device, avoided a series of accidents that lost efficacy and produce because of lightning protection device;
3, adopt the modular connect-disconnect structure, it is convenient to change, and practices thrift cost, and more environmental protection;
4, module can snap in the wide guide rail structure of 35mm, conveniently assemble and disassemble, and fully with international and national standard unification, and general, quick, reliable and convenient.
Description of drawings
