Standard components of the TMOV as Surge Protector can not only be used for an independent surge suppressor mounted on equipment
In, and the component of Surge Protector (such as SPD, TVSS) can be used as.The classical insulation of TMOV and common MOV parameters
It is completely the same.MOV (metal oxide varistor) is concatenated with TCO (Thermal Cutoffs), has no effect on the electric property of MOV.
Wherein, the first branch is：The branch that one TMOV1 of resistance, one G1 of gas-discharge tube connect with two TMOV2 of resistance, energy
It is enough realize respectively firewire input terminal L10 and ground wire input terminal PE be isolated and zero curve input terminal N10 and ground wire input terminal PE

Thermal protection.The second branch is：The branch that three TMOV3 of resistance connects with two G2 of gas-discharge tube.Third branch is：Resistance four
The branch that TMOV4 connects with three G3 of gas-discharge tube.
It is more reliable than only with single TMOV using multiple TMOV parallel connections, because being protected using single TMOV, once
The TMOV fails, then will just lose protection by protection equipment, and after using several TMOV parallel connections protection, in TMOV doublets
In, if one is damaged, other intact persons can still undertake protective effect.And in the protection field applied to larger transient state overcurrent
During conjunction, multiple TMOV parallel connections can provide relatively low clamping voltag, improve the ability for transient state overcurrent of releasing.Similarly, is taken
The mode of one branch, the second branch and third branch circuit parallel connection, it is more reliable than single branch.
In the circuit of TMOV and GDT tandem compounds, GDT seems to play on-off action, when not having transient overvoltage effect
When, it can keep apart TMOV and supply voltage, not apply power-frequency voltage, can be with almost without leakage current in TMOV
Effectively solve the problems, such as that the leakage current in TMOV constantly increases.If individually GDT using in a power, GDT can be generated
Afterflow, however, when TMOV is concatenated with GDT, TMOV therebetween can just cut off afterflow.
In order to observe the working condition of surge protection unit in time, it is provided with indicator light.The temperature of one TMOV1 of resistance

Another pin of Thermal Cutoffs be connected.Indicator light LED is also what is connected with each Thermal Cutoffs, when MOV is worked normally
When, indicator light is bright, internal to be presented short-circuit condition when MOV excess temperatures, and entire MOV becomes a good conductor, and excessive electric current
MOV and fuse are flowed through within the extremely short time, so as to cause blown fuse, indicator light extinguishes.In addition sound can also be utilized
Sound alarm unit or sound and light warning unit carry out alert operation during Thermal Cutoffs fusing.
For this surge protection unit when breaking down, device had thermal tripping defencive function, can disconnect immediately and electric
The connection of net improves protective capability and reliability, protects subsequent cell.
