Description
Technical field
The utility model belongs to the surge protection technical field of electronic electric equipment.
Background technology
Thunder and lightning is a kind of special weather phenomenon of by charged cloud, aloft being discharged and being caused.Thunder and lightning is the major reason that causes electronic equipment to damage, and it threatens the safe and stable operation of the every field electronic informations such as building, railway, civil aviaton, communication, industry control, military affairs.On the metallic circuits such as the power line that is connected with electronic equipment, holding wire and control line, surge protector (SPD) being installed is one of important measures of lightning protection.Surge protector has been widely used in various fields, has important effect in lightning protection.The quality of its state directly affects its lightning protection effect, thereby the safety of protection equipment is brought hidden danger.
The backup protection equipment of existing SPD comprises heat protection and overcurrent protective device, and overcurrent protective device adopts fuse or circuit breaker usually.But when power system failure, SPD cross flow short-circuit, power current by the time, its current value does not likely reach the startup value of overcurrent protective device, overcurrent protective device is failure to actuate; Thermel protection device, due to heat conducting speed restriction, also is failure to actuate, and causes power current to continue to pass through, and SPD is on fire in the lightning protection component heating.If the startup value of overcurrent protective device is selected little,, though can start, be difficult to resist the impact of lightning current, cause the SPD lightning current of can't normally releasing.Therefore there is serious blind area in existing overcurrent protective device to the protection of SPD, overcurrent protective device and thermel protection device all are failure to actuate in this zone, can't disjunction SPD fault paths, and the protected equipment of serious threat.
The utility model content
The overcurrent protective device that the utility model integrates lightning protection component, consist of the electromagnet with electric current sort channel and tripping mechanism, with the thermel protection device that is formed by bimetal leaf and tripping mechanism; residual voltage is lower; improve lightning protection effect, effectively solve the problem that above-mentioned backup protection equipment is failure to actuate.
The utility model is by the following technical solutions: the utility model is the surge protector for the power electronic circuits system; described surge protector comprises section breaker, tripping mechanism, has the electromagnet of electric current sort channel, bimetal leaf, lightning protection component and upper and lower terminals; all being arranged in a housing, is the Novel electric surge protector of an integral body.
Described upper terminals and section breaker, the electromagnet with electric current sort channel, lightning protection component, lower terminals are connected in series; Electromagnet with electric current sort channel can be controlled the tripping mechanism motion, thereby drives section breaker; The temperature of lightning protection component reaches bimetal leaf by hot conductive patch, and during excess Temperature, bimetal leaf can be out of shape the motion of drive tripping mechanism, drives section breaker.
Of the present utility model being characterised in that:
1. this Novel electric surge protector is integrated in one lightning protection component and thermel protection device and overcurrent protective device, and is easy for installation;
2. this Novel electric surge protector efficiently solves the problem of existing overcurrent protective device protection blind area.
3. when the deteriorated power frequency leakage current of lightning protection component reached certain value, the lightning protection component shell temperature also rose to certain altitude, and the intensification that causes due to the power frequency leakage current is the process of a slow gradual change, and the requirement of dangerous SPD path is cut off in the distortion that can meet bimetal leaf.The material of this bimetal leaf, size can be calculated according to the displacement of lightning protection component dangerous temperature value and promotion tripping mechanism;
4. work as power system failure, power current flows through, during lightning protection component inefficacy short circuit, has the electromagnet of electric current sort channel because coil flows into power current, push rod is ejected, and the displacement that ejects and dynamics are enough to drive the tripping mechanism motion, drive section breaker, in time cut off the SPD path, prevent excess Temperature lightning protection component (displacement and the dynamics that push rod ejects and flow through the size of current of coil on fire, the thickness of coil, the design of the number of turn of coil and electromagnet inside is relevant, can the ejection that determine push rod promote tripping mechanism, this a series of parameter value is by calculating), this moment, the temperature of lightning protection component can rise, but because temperature conduction is excessively slow, the deformation velocity of bimetal leaf is difficult in the front action on fire of lightning protection component fault,
5. when lightning current flows through, its current value is very high to the rate of change of time, coil on described electromagnet with electric current sort channel has certain inhibitory action to this high-frequency current, cause only having the small part electric current to flow through soon coil, produced very high voltage between two spheric electrodes, two electrode moments were punctured, and lightning current passes through rapidly; The electric current that flow through the small part of coil this moment also can make the electromagnet push rod eject and regain rapidly, but the displacement of this moment can not promote tripping mechanism, and the assurance lightning current is released smoothly.
