Description
Technical field
The utility model relates to a kind of overvoltage protection, relates in particular to a kind of novel surge protector with two tripping functions with greater security and reliability.
Background technology
Surge protector (SPD) is a kind of low-voltage variation device commonly used; under normal circumstances; it is in high impedance status; in case and circuit is because of thunderbolt or other reason when surge occurring; its meeting conducting in the extremely short time; lightning current or overvoltage are introduced the earth by earth connection, come equipment on the protection circuit with this.When surge protector causes deterioration because of a variety of causes, can swash acute the heating in the surge protector at this moment, thereby make the trip gear action in the surge protector, surge protector and circuit are broken away from, prevent surge protector " short circuit ", make the line accident extension.
Along with the extensive use of various device, people have proposed more and more higher requirement to the stability of power supply, simultaneously the performance of surge protector are also had higher requirement.The SPD of Shi Yonging has only a tripping function and the function of cutting off the electricity supply automatically in the market, has certain safety and stable hidden danger.
The utility model content
The utility model is exactly to provide a kind of have greater security and reliability for the problem that solves above-mentioned prior art existence, has two tripping functions and novel surge protector simple in structure.
The purpose of this utility model is achieved through the following technical solutions:
A kind of novel surge protector with two tripping functions, comprise a module carrier, also comprise two releasing structures, described pair of releasing structure comprises a graphite assembly and at least two the dropout electrodes that are sleeved in this module carrier, and described dropout electrode and graphite assembly are fixed by soldered; Described pair of releasing structure also comprises the trigger notice device, and described trigger notice device is installed on the module carrier, and the positioning of electrode of being threaded off limits.
Described dropout electrode is installed in the relative or adjacent side of module carrier.
Described trigger notice device is the indicator board that driven by elastomeric objects.
Described pair of releasing structure also comprises the remote signalling notifying device, and described remote signalling notifying device is installed in the module carrier, and is subjected to trigger notice device alignment restrictions.
Described remote signalling notifying device is the remote signalling push rod, described remote signalling push rod comprises the remote signalling push rod position location of remote signalling push rod elastomeric objects and at least two symmetries, described remote signalling push rod is driven by remote signalling push rod elastomeric objects, and is subjected to trigger notice device alignment restrictions by remote signalling push rod position location.
Compared with prior art, the utlity model has following beneficial effect:
A kind of novel surge protector that the utility model provides has two releasing structures; two tripping functions have been realized and the function of cutting off the electricity supply automatically; solved cut off the electricity supply automatically problem and believe distant output problem of two dropouts; fail safe, sensitivity and the reliability of SPD have been increased; and simple in structure, be suitable for suitability for industrialized production.

Embodiment
Describe the utility model in detail below in conjunction with accompanying drawing.
Shown in Fig. 1-2, a kind of novel surge protector with two tripping functions, comprise a module carrier 6, also comprise two releasing structures, this pair releasing structure comprises that a graphite assembly 1 and at least two dropout electrode 3(of being sleeved in this module carrier 6 are example with two dropout electrodes 3 here), two dropout electrodes 3 are installed in two sides module carrier 6 relative or adjacent (here to be example relatively), and fix by soldered with graphite assembly 1; This pair releasing structure also comprises the trigger notice device, and the trigger notice device is installed on the module carrier 6, and electrode 3 alignment restrictions of being threaded off.The trigger notice device specifically has various ways, here be example with two indicator boards that driven by elastomeric objects that are distributed in module carrier 6 relative both sides, indicator board 2 is driven and electrode 3 alignment restrictions of being threaded off by elastomeric objects 4, and elastomeric objects 4 also is two, is installed in two indicator board 2 the insides respectively.
When surge protector is under the normal condition; what faulty indication window window showed is the green position 11 of graphite assembly 1; two dropout electrodes 3 weld together by soldered and graphite assembly 1, and indicator board 2 promotes by elastomeric objects 4 and limited by dropout electrode 3.
Violent heating in the graphite assembly 1 under being in abnormality, soldered place 31 temperature increase, when reaching uniform temperature, will thread off, dropout electrode 3 flicks the restriction to indicator board 2, elastomeric objects 4 will promote indicator board 2 and up move, and the red position 21 on the indicator board 2 will appear at faulty indication window window place, and the green position 11 of graphite assembly is instructed to the red position 21 of plate and covers, give User Alarms, as shown in Figure 3.
This pair releasing structure also comprises the remote signalling notifying device, and the remote signalling notifying device is installed in the module carrier 6, and is subjected to trigger notice device alignment restrictions.The remote signalling notifying device specifically has various ways, is example with the remote signalling push rod 5 that is installed in the module carrier 6 here, and remote signalling push rod 5 is installed in below the graphite assembly 1 and by module carrier 6 and two indicator boards 2 and locatees; Remote signalling push rod 5 comprises the remote signalling push rod position location 51 of remote signalling push rod elastomeric objects 41 and at least two symmetries, remote signalling push rod 5 is driven by remote signalling push rod elastomeric objects 41, and is subjected to trigger notice device (being indicator board 2 here) alignment restrictions by two remote signalling push rod position locations 51.
The key that the utility model is realized is an equilibrium principle of having utilized lever, and when surge protector is under the normal condition, remote signalling push rod 5 can not be moved by the restriction of two indicator boards 2, and remote signalling push rod position location 51 is in poised state, as shown in Figure 4.When being under the abnormality, the soldered place 31 on arbitrary limit is because of the product abnormal heating or electric current is excessive threads off, dropout electrode 3 flicks the restriction to indicator board 2, indicator board 2 moves upward under the promotion of elastomeric objects 4, will make remote signalling push rod position location 51 disequilibriums, as shown in Figure 5, remote signalling push rod elastomeric objects 41 will promote remote signalling push rod 5 and move upward and produce inefficacy, and the switch that remote signalling push rod 5 is controlled also can corresponding actions and can in time warning message be told to the user.
More than disclosed only be several specific embodiments of the application, but the application is not limited thereto, any those skilled in the art can think variation, all should drop in the application's the protection range.
