Description
Technical field
The utility model relates to floating roof tank thunder and lightning tripper, especially a kind of Novel Lightning circuit breaker.
Background technology
Voltage-limiting surge protector belongs to easy aging class thermal breakdown product, and thunder and lightning and overvoltage can cause the progressively increase of its inner power frequency leakage current frequently, final generation thermal breakdown phenomenon.For reducing voltage-limiting surge protector, above-mentioned fault occurs, Industry code requirements is series trip device on voltage-limiting surge protector, stops and reduces because surge protector damages the generation of the user's power-off illegally accident caused.
Owing to clearly not specifying and the tripper technology category of connecting and parameter on specification surge protector in industry standard, the broken circuit protecting equipment that surge protector popular is at present connected in series has two classes: miniature circuit breaker and fuse.But many problems have been there is in actual motion.The circuit breaker that surge protector is connected disjunction because bearing lightning impulse, causes surge protector to lose efficacy, or when selecting the circuit breaker of larger through-current capacity; under power current; cannot disconnect, cause surge protector generation thermal breakdown, even cause fire incident.Lack a kind of thunder and lightning circuit breaker reliably at present.
Utility model content
In order to solve the deficiencies in the prior art, the utility model provides a kind of Novel Lightning circuit breaker.This thunder and lightning circuit breaker can realize the safety relief of lightning current when there is thunderbolt, power current release value exceed load current value time, disconnect fast, ensure the safe operation of equipment.
The utility model adopts following technical scheme:
A kind of Novel Lightning circuit breaker, comprise gap discharge module, inductor module and breaker module, described inductor module is connected with breaker module, and inductor module is connected with breaker module afterwards and gap discharge wired in parallel forms Novel Lightning circuit breaker;
The gap discharge module of Novel Lightning circuit breaker, inductor module and breaker module are encapsulated in the shell of Novel Lightning circuit breaker, and the shell of Novel Lightning circuit breaker is identical with the normal circuit breaker shell sizes of same model.
A kind of Novel Lightning circuit breaker of the utility model, described gap discharge module comprises the minimum discharging gap in gap, ensures that lightning current passes through from gap discharge module.
A kind of Novel Lightning circuit breaker of the utility model, described discharging gap is 2mm-25mm.
A kind of Novel Lightning circuit breaker of the utility model, described breaker module comprises the circuit breaker that transfinites, and circuit breaker is by being less than the power current of load current value, and disrupts is greater than the power current of load current value.
A kind of Novel Lightning circuit breaker of the utility model, the two ends of described Novel Lightning circuit breaker are in series with surge protector, and surge protector comprises discharging gap, gas-discharge tube, piezo-resistance, twin zener dioder and choking-winding.
The utility model adopts the Advantageous Effects as above acquired by technical scheme:
A kind of Novel Lightning circuit breaker, comprise gap discharge module, inductor module and breaker module, inductor module is connected with breaker module afterwards and gap discharge wired in parallel forms Novel Lightning circuit breaker, achieves the quick switching that thunder and lightning is released and power current is released.
Accompanying drawing explanation
Fig. 1 is Novel Lightning breaker connection schematic diagram.
Embodiment
1 embodiment of the present utility model is described further by reference to the accompanying drawings:
A kind of Novel Lightning circuit breaker, comprises gap discharge module, inductor module 2 and breaker module 3.Inductor module 2 and breaker module 3 wired in series, inductor module 2 forms Novel Lightning circuit breaker with gap discharge wired in parallel after connecting with breaker module 3, and Novel Lightning circuit breaker achieves the quick switching that lightning current is released and power current is released.The gap discharge module of Novel Lightning circuit breaker, inductor module and breaker module are encapsulated in the shell of Novel Lightning circuit breaker, and the shell of Novel Lightning circuit breaker is identical with the normal circuit breaker shell sizes of same model.The shell of Novel Lightning circuit breaker is provided with air trip switch, and air trip switch and circuit breaker respond.
Gap discharge module comprises the minimum discharging gap in gap 1, and discharging gap is 2mm-25mm, ensures that lightning current passes through from gap discharge module and releases.When being struck by lightning, portable protective gaps is first breakdown because of overvoltage, is released by a large amount of lightning current, and overvoltage is significantly declined, thus plays the effect of protection circuit and electric equipment.
Breaker module 3 comprises the circuit breaker that transfinites, and circuit breaker is by being less than the power current of load current value, and disrupts is greater than the power current of load current value.When power frequency leakage current exceedes load current value, circuit breaker disconnects immediately, ensures device security, can realize the defencive function of normal circuit breaker.
Inductor module 2 can pass through electric current when power current, and when lightning impulse, induction reactance is very large, and lightning current cannot pass through smoothly, and lightning current is passed through from gap discharge module 1.
The two ends of Novel Lightning circuit breaker are in series with surge protector, protection Novel Lightning circuit breaker.Surge protector comprises discharging gap, gas-discharge tube, piezo-resistance, twin zener dioder and choking-winding.When the interference in the external world produces suddenly peak current or peak voltage, surge protector can be shunted within the extremely short time in conducting, thus avoids peak current or peak voltage to cause damage to the equipment in loop.
The normal circuit breaker of Novel Lightning circuit breaker and same model measure-alike, directly can replace use.
Above-mentioned Novel Lightning circuit breaker is one pole simply connected thunder and lightning circuit breaker, is connected in the loop needing protection.Above-mentioned Novel Lightning circuit breaker is bipolar simply connected thunder and lightning circuit breaker, is connected on respectively in the different circuit needing protection.Above-mentioned Novel Lightning circuit breaker is three pole simply connected thunder and lightning circuit breakers, is connected on respectively in the three-phase loop needing protection.
Certainly; more than illustrate and be only preferred embodiment of the present utility model; the utility model is not limited to enumerate above-described embodiment; should be noted that; any those of ordinary skill in the art are under the guidance of this specification; made all equivalently to substitute, obvious variant, within the essential scope all dropping on this specification, protection of the present utility model ought to be subject to.
