Description
Technical field
The present invention relates to the technical field of surge protector equipment, particularly relate to a kind of surge protector standby
Protection intelligence release unit.
Background technology
The research of low-voltage distribution system shocking preventing technology in recent years is developed rapidly with application.Surge protection
Device (SPD) is main protective device, and disconnector and voltage dependent resistor chip (MOV) in SPD
It is two parts of core the most.The most inevitably be short-circuited fault due to SPD,
The additionally core devices MOV meeting ageing failure of voltage restricted type SPD, if do not taked safeguard procedures, it will
Bring the catastrophic consequences such as fire, so SPD is protected greatly by the disconnector of design configurations difference in functionality
Important.
Disconnector be a kind of can during SPD degradation failure from power-supply system disconnect device, have built-in and
Two kinds of major functions of external, have heat protection function and excess current protective function.It is described below the most domestic
Outer hot release unit technology status and overcurrent disengaging technology status:
1, current domestic and international hot release unit technology status
The disconnector with heat protection function is built-in structure, according to GB18802.1-2011 " low pressure
Surge protector (SPD) Part I of distribution system: performance requirement and test method " standard,
Requirement in IEC61643.1: A, bear operating duty cycle test ability；B, transient overvoltage ability；C、
Limit the ability of MOV degradation in SPD；D, SPD surface temperature 120K to be less than.Therefore, depart from
The heat protection function of device is that SPD is prerequisite.
The disconnector of heat protection function mainly control when MOV is deteriorated to a certain degree in time SPD from electricity
Origin system breaks.MOV deterioration is characterized as that power frequency leakage current increases.MOV heating aggravation makes caloric value
With heat dissipation capacity disequilibrium.When deteriorating leakage current ＞ 40mA through experimental results demonstrate as SPD, in temperature
Rise and cause burning.
The disconnector of heat protection function is by having a material of hot operating chacteristics or element detects metal electricity
Temperature fusing at pole.Ensure at SPD shell disconnector deenergization before combustion.Currently used
Hot melt performance materials of breaking is low melting point alloy, and low alloy material must have good physical and chemical performance
While solderability, mechanical strength to be had and temperature characterisitic, due to the uniformity of low melting point alloy
Poor, the discreteness of welding procedure and manufacture structural manufacturing process precision, spring tension, low-temperature alloy adhesion
Deng, this is all the reason of current hot disconnector performance extremely unstable.Therefore, often there is the weight that SPD burns
Major break down produces.
2, overcurrent departs from technology status the most both at home and abroad
The overcurrent of SPD departs from for external, general select breaker and fuse to be short-circuited at SPD therefore
SPD and electrical network is made to depart from during barrier.Selection gist according to SPD overcurrent protective device finds.Guarantee thunder and lightning
When stream flows through overcurrent protection be failure to actuate with power supply main switch QF1 and SPD overcurrent protection main switch (with
It is referred to as down surge protector back-up protection) there is the selective problem of the superior and the subordinate, owing to QF2 is SPD in QF2
It is short-circuited what fault shielded.And fault to be short-circuited is to deteriorate due to MOV chip mostly,
Thermal protection disconnector departs from thorough and that temperature rise is burnt and caused short circuit and account for exhausted major part.Therefore, often
Protection after protection can only play fault after rule, and the function without external hot protection is maximum defect.
