Abstract
The utility model relates to a full electronic lightning protection surge protector comprising at least one discharging circuit. The discharging circuit is connected between any two of a live wire, a null line, and a ground wire and is characterized by comprising a piezoresistor in series with a temperature fuse. The temperature fuse is abutted against the piezoresistor. The full electronic lightning protection surge protector has advantages of a full electronic structure, small size, large thunder and lightning current flow, and low residual voltage. In addition, the surge protector has a thermal detachment protection function, a computer network management remote communication signal interface, a function of operation indication, a function of failure alarm indication, conspicuous indication signals, and a self-checking function of a failure alarm signal and a computer network management signal. No open fire generates when thermal detachment happens. The full electronic lightning protection surge protector is accurate, reliable, and safe and has an explosion-proof function.
Description
(1) technical field
The utility model relates to a kind of full electronic thunder proof surge protector; in particular a kind of can be within the shortest time (nanosecond), the high energy pulse overvoltage that produces because of sense thunderbolt or other reason (such as industrial operation) on the low-voltage distributing line of releasing is to the full electronic thunder proof surge protector of protecting on the ground wire.
(2) background technology
Along with the progress of science and technology, the popularizing of a large amount of sophisticated electronicses, electric home appliances, computer data equipment, the loss that the surge that damage to crops caused by thunder and other reason form causes is year by year ascendant trend, has caused the great attention of academia and authorities.The development of China's lightning-protected product, production have obtained fast development on the basis of introducing, digest, absorbing.The raising of people's lightning protection consciousness makes Thunder Protection form a kind of industry, and has possessed certain scale.
The low-tension supply thunder proof surge protector that generally uses on implementation and the engineering in the market is the external technology of introducing mostly; it is a kind of lightning protection device of accurate electronic type; heat disengaging, webmaster signal, Indication of Losing Efficacy; all realize by machinery control contact; operation precision is poor, reliability is low; when in the lightning discharge process, going out heat and now breaking away from, break away from contact and will produce spark and cause that easily lightning protection device bursts, especially will bring out secondary disaster in inflammable and explosive environment.
(3) summary of the invention
The purpose of this utility model is that pin aims at the technological deficiency of electronic type thunder proof surge protector, and a kind of do not damaged by surge than the power consumption equipment on safer more reliable, the protection low-voltage supply line of accurate Electronic Lightning Protection Surge Protector, full electronic thunder proof surge protector is provided.
The utility model is achieved by the following technical solution:
A kind of full electronic thunder proof surge protector; comprise that at least one is connected to the wherein discharge circuit between two lines of power firestreak, zero-power line and ground wire; it is characterized in that: described discharge circuit is composed in series by a piezo-resistance and a Temperature protection, and this Temperature protection is close to piezo-resistance.
Above technical scheme can be further improved by following measures:
It also comprises the fault alarm circuit, and the Temperature protection of fault alarm circuit is close to the piezo-resistance of discharge circuit.
Described fault alarm circuit comprises resistance, self check button, Temperature protection, Indication of Losing Efficacy lamp and run indicator, resistance, Indication of Losing Efficacy lamp and run indicator are connected into the indication loop, indication loop one termination power live wire, another termination zero-power line or ground wire, the self check button is normally closed switch, and the self check button is with in parallel with the Indication of Losing Efficacy lamp again after Temperature protection is connected.
Described piezo-resistance and one can provide the Temperature protection of webmaster signal to be close to.
Abovementioned technology can be selected a use, also can be used in combination.
In the full electronic thunder proof surge protector core discharge paths be connected across between protected low-tension supply live wire L or zero line N and the ground wire PE.Under normal circumstances, full electronic lightning protection device Surge Protector is in high-impedance state, does not affect the normal operation of electrical network.When electrical network meets indirect lightning strike or transient overvoltage appears in switching manipulation; the thunder proof surge protector of this full electronic is discharged rapidly by the resistance of high resistant step-down within the time of nanosecond immediately; powerful pulse current is released into ground, thereby play the purpose of protecting power consumption equipment.After the thunderbolt pulse, the full electronic thunder proof surge protector returns to again high-impedance state, and electrical network normally moves.
The heating if full electronic thunder proof surge protector discharge device lost efficacy, when heating temp reached 115 ℃, the Temperature protection that heat breaks away from temperature control electronic device-discharge circuit cut off being connected of inefficacy discharge device and protected circuit automatically.Temperature control electronic device-the Temperature protection of signal system is sent fault alarm and computer webmaster signal.
The utility model has the advantages that: the full electronic structure, volume is little, the thunder and lightning through-current capacity is large, residual voltage is low, have heat breaks away from defencive function, has computer webmaster remote signals interface, and it is eye-catching to have an operation indication, fault alarm indication, index signal.Have fault alarm, computer webmaster signal self-checking function.Heat does not have naked light to produce when breaking away from.Has explosion prevention function accurately, reliably, safely.
