Description
Technical field
The present invention relates to protection technical field of electric equipment, especially a kind of new hot plug for overvoltage protection are continuous
Electric-type surge protector.
Background technology
Traditional surge protector is referred to as the titles such as Surge Protector, lightning protection grid.Its main effect contributes to protect
Class signal detects and control device, prevents the external disturbance such as electrical surge, transient voltage as caused by thunderbolt or high-voltage switch gear.
In the surge impact of one relative brevity, by the way that transient current is released into ground, by the voltage clamping between signal wire at one
Level of security, and ensure the signal normal transmission on signal wire, escort safely for industrial automation equipment.Inside it at least
Formed comprising a non-linear element, before transient state surge future, high resistance is presented in this element, to not had by protection circuit
Influence；And during transient state surge arrival, this element is changed into rapidly low resistance, and surge current is released, will be by protection equipment two
The voltage at end is limited in relatively low level.When terminating to surge, self- recoverage is high-impedance state to the non-linear element again.It is wide at present
It is general be used for process industry, oil-gas exploration and exploitation, draining and sewage disposal technology, energy technology, traffic technique and building from
The protection of the systems such as dynamicization.
At present, the surge protector of class signal equipment protection is commercially it is well known that more traditional is the knot of integral type
Structure.In recent years, also there is the surge protector structure of plug type, i.e., protect connection terminal module and overcurrent/overvoltage
Shield module makes two parts, can be rapidly performed by installing and changeing, but when changing product protection module, transmission channel occurs
Signal transient interrupt, often bring very big broken string blind spot, the presence pair of the unreliable phenomenon of swapping process to real-time monitoring system
High-precision real-time monitoring system causes very big loss.But the Surge Protector structure of traditional monoblock type, in damage of product more
When changing, all wiring are not only dismantled, also needs to carry out complete machine dismounting, then more renews surge protector up again, and do again
Wiring works.Such a integral type surge protector dismounting is complicated, when increasing quantities, and changing complete machine surge protector, nothing
Increase cost in shape.Traditional Integral electric surge protector and plug type surge protector lack in the switch board of installation level of confidentiality
Weary label dust cap and industrial position number mark, huge trouble is brought to instrument protection and physical cabling installation discrimination.
Such as Chinese invention patent《Plug the continual Surge Protector of protection module signal》, Application No.
201320354122.1, a kind of unbroken Surge Protector of signal is disclosed, can when Surge Protector damage needs to change
To have connected the binding post base of intact wire without pulling down, it is only necessary to change and insert superincumbent hot plug module.But mesh
Preceding hot plug module is complicated, without clearly instrument protective cover and industrial position number etc., the contact of the product plug-in module
Point reliability is not high.If module is in contact loosening in plug, when interior contact is bad, surge protector can be caused to plug
The forfeiture of the uninterrupted function of module by signal, in a disguised form lose the performance of product in itself.
