Description
Technical field
The utility model is related to protection of technical field of electric equipment, and a kind of Novel hot for overvoltage protection plugs not electricity cut-off type surge protector.
Background technology
Traditional surge protector is referred to as the title such as Surge Protector, lightning protection grid.Its main effect contributes to protect class signal detection and control equipment, prevents electrical surge, the external disturbance such as transient voltage caused by thunderbolt or high-voltage switch gear.In the surge impact of a relative brevity, by transient current being released to ground, by the voltage clamping between holding wire a level of security, and guaranteeing the signal normal transmission on holding wire, escorting safely for industrial automation equipment.It is internal including at least a non-linear element composition, and before transient state surge future, this element presents high resistance, does not affect by protection circuit；And during transient state surge arrival, this element is changed into rapidly low resistance, is released by surge current, relatively low level will be limited in by the voltage at protection equipment two ends.When terminating to surge, this non-linear element self-recoverage again is high-impedance state.It is now widely used in the protection of the systems such as process industry, oil-gas exploration and exploitation, draining and sewage disposal technology, energy technology, traffic technique and building automatic.
At present, the surge protector of class signal equipment protection is commercially it is well known that relatively more traditional is the structure of integral type.In recent years; also the surge protector structure of plug type is occurred in that; two parts will be made by connection terminal module with overcurrent/over-voltage protection module; can be rapidly performed by installing and changeing; but when changing product protection module; the signal transient that transmission channel occurs is interrupted, and often brings the biggest broken string blind spot, the existence of swapping process unreliable phenomenon that high accuracy real-time monitoring system is caused the biggest loss to real-time monitoring system.But traditional all-in-one-piece Surge Protector structure, when damage of product is changed, not only to dismantle all wiring, also need to carry out complete machine dismounting, the most more renew surge protector up, and do the work of wiring again.This kind of integral type surge protector dismounting complexity, increases quantities, and when changing complete machine surge protector, virtually increases cost.In the switch board installing level of confidentiality, traditional Integral electric surge protector and plug type surge protector shortage label dust cap and industry item identify, and distinguish instrument protection and physical cabling installation to bring huge trouble.
Such as Chinese utility model patent " the plug protection continual Surge Protector of module by signal "; Application No. 201320354122.1; disclose a kind of unbroken Surge Protector of signal; when Surge Protector damage needs to change; the binding post base having connected intact wire can be pulled down, it is only necessary to change the superincumbent hot plug module of plug-in mounting.But hot plug module structure is complicated at present, instrument protective cover and industry item etc. the most clearly, the contact safety of this product plug-in module is the highest.If module comes in contact when plug loosening, when interior contact is bad, the forfeiture of the surge protector uninterrupted function of plug-in module signal can be caused, in a disguised form lose the performance of product itself.
